ABSTRACT. Using firm-level panel data, this article examineswhether spillovers from foreign direct investment (FDI) make acontribution to productivity growth in Chilean manufacturingfirms. The main contribution of this work is to apply a methodologyto estimate, in a consistent manner, the productivity impactof investment climate variables, such as FDI. With this aim, thespillover effects from FDI are analyzed using a stochastic frontierapproach (SFA). Productivity growth is decomposed using a gener-alized Malmquist output-oriented index. The results show positiveproductivity spillovers from FDI; higher competition is associatedwith larger spillovers; and firms with high R&D effort gain morespillover benefits compared to those with less R&D effort.

INTRODUCTION

Foreign direct investment (FDI) is believed to provide recipient countries withknowledge transfer as well as capital. The expectations to obtain productivityspillovers through knowledge transfers have led to the development ofpolicies oriented toward the generation of favorable framework of FDI innumerous countries. In this situation, it is important to ask ourselves, doesFDI lead to productivity spillovers? In order to answer this question, severalstudies have been conducted in Latin American countries. For example,Kokko, Tansini, and Zejan (2001) examined intra-industry spillovers fromFDI in Uruguayan manufacturing plants in 1988. Chudnovsky, Lopez, andRossi (2008) assessed the amounts of FDI inflows in Argentina during the1990s; Waldkirch (2010) analyzed the FDI in Mexico since the inception ofthe North American Free Trade Agreement; and Fernandes and Paunov(2012) examined the impact of substantial FDI inflows of producer service sec-tors in relation to the total factor productivity of Chilean manufacturing firms.

Taking into account these findings and motivated by additional resultsin the extant literature, this article specifies the conditions under whichindustries added efficiency (productivity of the factors) as well as whetherspillovers from FDI contribute to productivity growth. In others words, ouranalysis extends this research and sheds light on the need to distinguish localestablishment characteristics when discussing potential benefits from FDI.

The main contribution of this work is to apply a methodology in order toestimate, in a consistent manner, the productivity impact of investment climatevariables, such as FDI. To do this, we apply the methodology to the data col-lected for investment climate assessments (ICA) surveys at firm level in Chile(focusing on the industrial sector).1 We have panel data (T¼ 3) for 2001, 2002,and 2003 from Chile’s ICA survey. Methodologically, we make use of thestochastic frontier analysis (SFA) as a robust parametric approach to estimateFDI productivity spillovers in Chilean manufacturing firms. To measure Chile’sIT services productivity we apply the method of data envelopment analysisand compute the Malmquist index to decompose the total factor productivity(TFP) growth into technical efficiency change (TEC), technological progress(TP), and scale efficiency change (SEC). The results show positive productivityspillovers from FDI—such that higher competition is associated with largerspillovers, and firms with high research and development (R&D) effort gainmore spillover benefits compared to those with less R&D effort.

This research is organized as follows. First, we present the frameworkproposed to analyze the relationship between technical FDI and productivityspillovers in the context of the Chilean industrial sector. Following is a criticalreview of the theoretical and empirical studies on productivity spillovers.Next, we develop a methodology of analysis: we will discuss estimation tech-niques followed by data sources and variable construction. The followingsection presents the main empirical results obtained. The main conclusionsand a brief discussion end the article, which leads into an explanation ofcertain policy implications.

THEORETICAL BACKGROUND AND HYPOTHESIS

Productivity—understood as the capacity an economy (company or business)has to obtain the greatest advantage of inputs with respect to the generatedoutput—is a long-existing concern. A first approach was to try to understand,in the most thorough way possible, the productivity of production factors,since this allowed us to evaluate the quality of an economy’s growth or theproduction of a company. In this context, the empirical literature studyingthe relationship between FDI, productivity, and growth is voluminous andconstantly expanding. Recent works, such as Contessi and Weinberger(2009) or Wooster and Diebel (2010), reviewed the empirical literatureon technology spillovers from FDI in developing countries. Contessi and

Weinberger reviewed the empirical literature that studies the relationshipbetween FDI, productivity, and growth using aggregate data; they focusedon two main questions: (i) whether there is evidence of a positive relationshipbetween FDI and national growth, and (ii) whether the output of ‘‘multina-tional sectors’’ exhibits higher labor productivity. The authors discussedhow microeconomic evidence and a number of aggregation and compositionproblems might help explain the ambiguous results obtained in this literature.Wooster and Diebel used a sample of 32 studies to determine which aspects ofstudy design and data characteristics explain the magnitude, significance, anddirection of spillovers from FDI. Results suggest (i) that spillover effects aremore pronounced when studies measure the effect of FDI spillovers on out-put, and they are more likely to be significant and positive for Asian countries;(ii) and that the possibility that the documented spillover effects from FDI indeveloping countries may be partly a product of model misspecification.

Most of the previous studies on FDI spillovers treat the specific mechan-isms of productivity spillovers as occurring in a ‘‘black box’’ (Gorg & Strobl,2001). These studies often assume that productivity spillovers from FDI occurautomatically because of foreign firms’ presence in domestic markets. Chan-nels of productivity spillovers are not explicitly taken into account in suchstudies. However, some studies make serious attempts to take into accountthe channels of productivity spillovers from FDI. According to Blomstromand Kokko (1998) and Kokko (1996), four fundamental mechanisms forproductivity spillovers have been derived:

1. Demonstration-imitation effect: Foreign firms in domestic markets cancreate demonstration effects upon domestic firms through direct imitationand reverse engineering (Das, 1987), or by means of innovation arisingfrom R&D (Cheung, 2010). In the words of Ornaghi (2002),demonstration-imitation effects occur if there are arms’ length relation-ships between multinational corporations (MNCs) and domestic firms.Domestic firms absorb more advanced production technologies and otherknowledge from MNCs. Ornaghi pleaded for the differentiation betweenchannels of technology spillovers in the case of process and productinnovations. The most important forms are imitation of managerial andorganizational innovation as well as imitation of technology.

2. Competition effect: The entry of MNCs may lead to greater competition indomestic markets, which then forces domestic firms to use their resourcesand technology in more efficient ways, thus leading to productivitygains (Wang & Blomstrom, 1992). According to Smarzynska (2003), thecompetition effect is when competition from MNCs force domestic rivalsto update production technologies and techniques to become more pro-ductive. The foreign linkage effect relates to export spillovers. Finally,Smarzynska distinguished between knowledge (copying technologiesof foreign affiliates, observation, or hiring workers trained by foreign

subsidiaries) and competition spillovers (MNC entry leads to more severecompetition and forces domestic firms to higher efficiency and search fornew technologies).

3. Foreign linkage effect: Foreign firms in domestic markets may also createproductivity spillovers to domestic firms through foreign linkage effects.According to Rodriguez-Clare (1996), foreign linkage effects may occurbecause MNCs give access to new specialized intermediate inputs orbecause domestic firms use local intermediate goods’ suppliers, whoseproductivity has been raised through the expertise of the MNC.

4. Training effect: Knowledge may spillover to domestic firms via labor turn-over; that is, when workers trained by multinational corporations move todomestic firms and bring with them the knowledge and other crucialintangible assets (Fosfuri, Motta, & Rønde, 2001). Gorg and Greenaway(2004) distinguished two mechanisms of the training effect: direct spil-lovers through complementary workers, and indirect mechanism whenworkers move and transfer knowledge between foreign and domesticfirms. According to Gorg and Strobl (2005), training effects take place ifthere are movements of highly skilled personnel from MNCs to domesticfirms. These employees may take with them knowledge that may beusefully applied in the domestic firm.

Heterogeneity of Domestic Firms and Industry Competition: SomeHypotheses

Industry competition and heterogeneity of domestic firms as determinants ofknowledge and FDI spillovers relates primarily to their technological capacity,human capital, and productivity. According to the empirical evidence, thesefactors determine domestic firms’ absorption capacity for knowledge andFDI spillovers. Our hypotheses are:

H1: High levels of competition (in terms of low Herfindahl-Hirschmanindex of industry concentration), positively influences spilloversfrom FDI (measured by the share of foreign firms’ output over totaloutput in the sector of activity).

Our first hypothesis relates to industry competition. According tothis hypothesis, higher competition is associated with larger spilloversfrom foreign presence in the industry; that is, positive productivity throughcompetition.

Competition may result in either positive or negative productivityspillovers for domestic firms. Aitken and Harrison (1999) argued that in theshort-run, the presence of foreign firms in an imperfect competition domesticmarket might raise the average cost of production of domestic firms throughthe ‘‘market stealing’’ phenomenon. Foreign firms with a lower marginal cost

have an incentive to increase production relative to their domestic compet-itors. The productivity of domestic firms will fall, as they have to spread fixedcosts over a smaller amount of output.

However, in the end, when all costs can be treated as variable costs, thereis a possibility for domestic firms to reduce their costs by allocating theirresources more efficiently and imitating foreign firms’ knowledge (Wang &Blomstrom, 1992). If the efficiency effect from foreign presence is larger thanthe competition effect, there can be positive productivity spillovers.

The predominance of liberalization-oriented policies over the past yearsversus policies oriented toward engaging FDI have meant a huge decrease interms of market concentration. However, industry structure remains animportant control variable to be included in this study of FDI and productivityspillovers.

Some studies found country-by-country empirical evidence supportingthis hypothesis in relation with industry competition. For example, in a studyconducted in Morocco, although Haddad and Harrison (1993) found noevidence of technology spillovers, the increased competition by foreigninvestors seemed to push local firms toward the best practice frontier inindustries with a low level of technology. On the other hand, Blomstrom,Kokko, and Zejan (1994), in a study conducted in Mexico, found that localcompetition correlates positively to imports of technology by MNEs.

H2: The level of R&D effort (defined as the total expenditures on R&Ddivided by the total sales) positively influences spillovers from FDI(measured by the share of foreign firms’ output over total outputin the sector of activity).

Our second hypothesis relates to the level of technological devel-opment=technological capacity. According to this hypothesis, firms withR&D expenditure gain more productivity spillovers from FDI than thosewithout R&D expenditure.

The mixed evidence of productivity spillovers leads to the argument thatfirm-specific characteristics (or absorptive capacity) may influence the abilityof domestic firms to gain productivity spillovers from FDI (Findlay, 1978;Glass & Saggi, 1998; Wang & Blomstrom, 1992). The most commonly usedmeasure of absorptive capacity is expenditure on R&D. Kathuria (2000) foundevidence in a study on an Indian manufacturing firm that local firms that investin learning or R&D activities receive high productivity spillovers, whereas thenon-R&D local firms do not gain much from the presence of foreign firms.This result indicates that productivity spillovers are not automatic conse-quences of the presence of foreign firms; rather, they depend on the effortsof local firms investing in R&D activities. Kinoshita (2001) found similar evi-dence in a study on Czech manufacturing firms, during 1995–1998. In a morerecent study of 12 Organisation for Economic Co-operation and Development

countries, Griffith, Redding, and Van Reenen (2004) confirmed that R&Dplays an important role in knowledge transfer, besides its role as a meansof innovation.

Some studies found country-by-country empirical evidence of thishypothesis, in relation with the level of technological development=techno-logical capacity. For example, Perez (1998), in a study conducted in the Uni-ted Kingdom and Italy, found that firms with a lower technological gap thantheir competitors experienced positive effects of increased foreign presence.Girma, Gong, and Gorg (2006), in a study conducted in China, found thatfirms that invest in R&D have positive FDI spillovers. Halpern and Murakozy(2007), in a study conducted in Hungary, found that firms with technology orR&D spending that is more advanced are likely to benefit more from the pres-ence of foreign firms. Finally, Abraham, Konings, and Slootmaekers (2010), ina study conducted in China, found that firms far away from the technologicalfrontier do not benefit from the presence of foreign firms, while firms operat-ing close to the frontier enjoy positive spillovers (manufacturing).

H3: The level of human capital (defined as the percentage of theworkforce with some university or higher education level) positivelyinfluences spillovers from FDI (measured by the share of foreignfirms’ output over total output in the sector of activity).

Our third hypothesis relates to the level of human capital. According tothis hypothesis, there is a positive productivity spillover from FDI. Accordingto Caves (1971), when MNCs establish subsidiaries overseas, they experiencedisadvantages in the form of access to resources and domestic demand,when compared to their local counterparts. In order to compete with dom-estic firms, MNCs need to possess superior knowledge. With this superiorknowledge, MNCs are often assumed to have higher performance levels thandomestic firms, in particular being more efficient and productive.

Some studies found country-by-country empirical evidence of thishypothesis, in relation to human capital. For example, Girma and colleagues(2006), in a study conducted in China, found that firms that invest in humancapital experience positive FDI spillovers. Gorodnichenko, Svejnar, andTerrell (2007), in a study conducted in Eastern Europe, found that firms witha higher educated workforce gain from the presence of foreign firms in theirindustry. Finally, Damijan, Rojec, Majcen, and Knell (2008), in a study conduc-ted also in Eastern Europe, found that Spillovers substantially depend on theabsorptive capacity of local firms measured by the level of human capital.

H4: The level of spillovers from FDI (measured by the share of foreignfirms’ output over total output in the sector of activity) positively influ-ences the change in the productivity growth and in their components(technical efficiency, technological progress, and scale efficiency).

Finally, our fourth hypothesis relates to productivity level. According tothis hypothesis, there are positive FDI spillovers to each component of pro-ductivity growth (TEC, TP, and SEC). According to Salim and Bloch (2009),the empirical studies usually assume that productivity advantage from FDIis exclusively contributed by technology transfers, because it is consistent withthe use of a conventional approach of production function. However, techni-cal and scale efficiencies have scarcely been studied in relation to productivitygains from FDI. In this context, Smeets (2008) argued that productivityspillovers from FDI should be defined broadly, as they are the result of newknowledge and not of new technology alone. Smeets defined knowledge asincluding technological managerial and production skills, which may contrib-ute to technical efficiency and the ability to exploit scale efficiency.

Some studies have found country-by-country empirical evidence of thishypothesis in relation to level of productivity. For example, Haskel, Pereira,and Slaughter (2007) in a study conducted in the United Kingdom, found thatless productive (and smaller) plants received, on average, stronger FDI spil-lovers than more productive (and larger) plants. Castellani and Zanfei, (2003)in a study conducted in Southern Europe, found that high productivity gapstended to favor positive effects of FDI. Examining Southern European firms,Damijan and colleagues (2008) found that FDI spillovers depend on theproductivity level of individual firms. Finally, Keller and Yeaple (2009), ina study conducted in the United States, found that relatively high productivityis required for a firm to acquire FDI-related spillovers.

METHOD

Estimation Techniques: Stochastic Frontier Analysis andMalmquist Index

This subsection proposes a brief assessment methodology for productivityspillovers in order to examine when spillovers from FDI contribute to pro-ductivity growth. The spillover effects from FDI will be analyzed using anSFA approach (Kumbhakar & Lovell, 2003). This approach uses the stochasticfrontier production function, following the guidelines set by Battese andCoelli (1988, 1993, 1995), and a generalized Malmquist output-oriented indexto decompose productivity growth (Orea, 2002). For more detailed andformal discussion, see Appendices A and B.

According to a number of authors (Aigner, Lovell, & Schmidt 1977;Meeusen & Van den Broeck, 1977), the production frontier model withouta random component can be written as yi¼ f(xi; b) � TEi, where yi is theobserved scalar output of the producer i, xi is a vector of N inputs used bythe producer i, f(xi; b) is the production frontier, and b is a vector of tech-nology parameters to be estimated. Finally TEi denotes the technical efficiencydefined as the ratio of observed output to maximum feasible output.2

A stochastic component that describes random shocks affecting theproduction process is added. These shocks are not directly attributable tothe producer or the underlying technology. These shocks may come fromweather changes, economic adversities, or plain luck. We denote theseeffects with expfvig. Each producer is facing a different shock, but weassume the shocks are random and are described by a common distribution.The stochastic production frontier will become: yi¼ f(xi;b) � TEi � expfvig. Ifwe assume that TEi is also a stochastic variable, with a specific distributionfunction, common to all producers, we can also write it as an exponentialTEi¼ expf�uig, where ui� 0, since we required TEi� 1. As a result, weobtain the equation: yi¼ f(xi; b) � expf�uig � expfvig.

Finally, if we also assume that f(xi;b) takes the log-linear Cobb-Douglasform,3 the model can be written as ln yi¼ b0þ

Pnbn ln xiþ vi�ui, where vi

is the ‘‘noise’’ component, which we will almost always consider as atwo-sided normally distributed variable, and ui is the non-negative technicalinefficiency component. Together they constitute a compound error term,with a specific distribution to be determined, hence the name of ‘‘composederror model’’ to which it is often referred.

On the other hand, the Malmquist Productivity Index (MPI) is a bilateralindex that can be used to compare the production technology of two firms.This index is also based on the concept of production function. In otherworks, the MPI is a function of maximum possible production, with respectto a set of inputs pertaining to capital and labor.

If we define Sa as the set of labor and capital inputs to the productionfunction of firm A, and Q as the production function of firm A, we could writeQ¼ fa(Sa). To calculate the MPI of firm A with respect to firm B, we must sub-stitute the labor and capital inputs of firm A into the production function of B,and vice versa. The expression for MPI is MPI ¼

Variables and Instruments

Table 1 presents a summary of the key variables used to empirically validatethe combined stochastic-inefficiency model for Chilean manufacturingindustries. Similar variables have been used by Escribano and Guasch(2005), who compared cross-country performances in Guatemala, Honduras,and Nicaragua. As shown in Table 1, the variables used in this study wereclassified into three groups: (1) variables that define the production frontier,(2) variables that define the term of inefficient production frontier, and (3)control variables for the second stage analysis.

In the first group, value added was collected (in terms of value of grossoutput minus intermediate inputs) as output and as inputs, capital stock (interms of Net book value of Machinery and equipment), and work (in termsof total number of permanent workers). In the second group the existence

dividing the capital stocks for each industry by labor input), and Real wage(defined as the total expenditures on personnel divided by the total numberof permanent workers) were included.

Statistical Source and Sample

These sections deal with the characteristics of the business and the investmentclimate in which firms operate. The statistical source used for this analysis isthe World Bank’s Enterprise Surveys (WBES). The WBES collects data fromkey manufacturing and service sectors in every region of the world. TheWBES use standardized survey instruments using a uniform sampling meth-odology to minimize measurement error and to yield data that are comparableacross the world’s economies. It is worth noting that the sample covers estab-lishments in nine industries, including six manufacturing sectors, informationtechnology, biotechnology, and fish farming. Furthermore, the sampleincludes firms of all sizes: micro (<16), small (16–49), medium (50–249)and large (250þ workers) firms.

The Core instrument comprises 11 sections. The first eight sectionscontain qualitative questions, which are based on a manager’s opinion onthe business environment and on motivation for business decisions. The nextsection, only included in the Manufacturing Module, contains questionsabout capacity (use of production capacity and hours of operation). The lastthree sections of the questionnaire deal with data specific to the transactionsbusinesses make in order to operate.

From Chile’s ICA survey we are able to form a balanced data panel (seeTable 2). We have observations for 2001, 2002, and 2003.

Table 3 shows the descriptive statistics of the variables taken intoaccount in order to conduct the empirical analysis for the entire sample.

Table 4 shows the descriptive statistics of the variables considered inorder to conduct the empirical analysis by sectors. It presents importantdifferences in terms of value added during the period considered.

RESULTS

When observing the whole of the Chilean industry (Table 5), we observevery similar values across sectors during the periods studied in terms oftechnical efficiency levels.4 In this context, improvement in the use of theirproductive inputs is close to 53%.

In terms of convergence the dynamic between the years considered isshown in Figure 1, and it illustrates the trends in convergence (divergence)and persistence (mobility) in the level of technical efficiency attained.For Chilean industry technical efficiency over the whole period, we detecta pattern of divergence and mobility.

Competition, Absorptive Capacity, and Productivity Spillovers

In this section hypotheses H1 and H2 are tested by estimating two alternativetechnical inefficiency functions to avoid the possibility of multicollinearity.The test of H1 includes a spillover variable, a competition variable (HHI),and an interacting variable of spillover and HHI (see Table 6). In order toevaluate the absorptive capacity of spillovers in the industry, the test of H2includes a spillover variable, an R&D effort variable, and an interactingvariable of R&D effort and spillover (see Table 7).

The estimation results of a translog stochastic production frontier (seeTable 6) show that the coefficients of labor and capital are expected to havepositive signs (in models 4 and 5). The positive and highly significant coeffi-cients confirm the expected positive and significant output effects of laborand capital. On the other hand, if we take into account the squared variableof labor [ln(Lt)]

2 in models 1, 2, and 3 we will observe a negative and statisti-cally significant 1% level, which indicated a decrease regarding labor perfor-mance. This cannot be confirmed in the case of the variable squared capital.However, the same is not true for the squared capital. The squared variableof capital [ln(Kt)]

2 in models 1, 2, and 3 is positive and statistically significantat a 5% level, which indicates an increasing return to capital. Furthermore,the estimated coefficient of the interacting variable between labor and capitalln(Lt)

�ln(Kt) in models 1, 2, and 3 is positive and significant at a 1% level, sug-gesting a substitution effect between labor and capital. The last finding isconsistent with classic works from Arrow, Chenery, Minhas and Solow(1961). These authors found empirical evidence that the elasticity of substi-tution between capital and labor in manufacturing may typically be less thanunity. However, these authors also found that there are weaker indicationsthat this conclusion is reversed in primary production.

An interesting result of this study is the estimated coefficients of the inef-ficiency function in the second part of the models in Table 6. The negativeand significant coefficient on the spillover variable (spillover) in Models 1,2, 3, and 4 in Table 6 implies a positive and significant efficiency spilloverin the Chilean industrial sectors. This result suggests that in the Chileanindustrial sectors foreign investments result in domestic firms utilizing theirresources in a more efficient way, which then leads to gains in productivity.

The positive coefficient of the interacting variable between concen-tration and spillovers S�HHI in Models 1, 2, 3, and 4 suggests that a lower con-centration is associated with larger spillovers from foreign presence. Fromthese findings, it may be inferred that domestic firms operating in a non-concentrated subsector of the Chilean industrial sectors may gain spilloverbenefits from foreign firms.

According to Salim and Bloch (2009), higher concentration is an inversemeasure of static competition that can protect inefficient firms. However, ahigher concentration can also be the result of dynamic competition amongfirms of differential efficiency that removes inefficient firms from the industryas argued by Demsetz (1973) and Peltzman (1977). The first argumentsuggests that HHI is associated with greater inefficiency, while the latterargument suggests that HHI is associated with lower inefficiency.

Table 7 presents the estimated parameters of productivity spillovers andabsorptive capacity.

In Table 7, the estimated parameters of production functions have asimilar sign and significance as in the baseline models shown in Table 6.The coefficient of the R&D dummy is positive and significant at the 1% level,

suggesting that firms with high R&D effort, on average, have lower efficien-cies compared to those with low R&D effort. The negative coefficient of theinteracting variable between R&D and spillovers (S�R&Dt) suggests that firmswith high R&D efforts gain more spillovers from foreign firms. Given thisresult, it is possible to infer that firms with high R&D effort can reap greaterbenefits from foreign firms’ presence by upgrading their knowledge and cre-ating innovation. This finding confirms that firms’ absorptive capacity (orfirms’ specific characteristic) determines productivity spillovers from FDI,as argued in some previous studies, for example, by Kathuria (2000).

Sources of Productivity Growth and FDI Spillovers

In this section, hypotheses H3 and H4 are tested estimating the indices ofTEC, TP, SEC and G0 using Equations [7] and [14] (see Appendix B); theaverage of these indices for the selected period (2001–2003) is presentedin Table 8.

Table 8 shows that a major contribution to productivity growth in theChilean industrial sectors comes from TP and from TEC—with the exceptionof the biotechnology sector. In contrast, the SEC indices are relatively low,suggesting that this component does not contribute much to productivitygrowth.

After obtaining the indices of Malmquist total productivity growth index(G0), TEC, TP, SEC, the next step is to estimate the contribution of FDIspillovers on the total factor productivity growth and its sources. Using theindices of TEC, TP, SEC, and G0 obtained from the decomposition, we thenestimate the impact of FDI spillovers on total factor productivity growth andits sources (see Table 9).

Similar to Salim and Bloch (2009), we propose a second step analysisproposed for these indices. To conduct the analysis, we include several

control variables, such as Foreign, Age, Human Capital, TechnologicalInnovation Subsidies, Depth of Capital, Real Wage, and Industrial sectors.

Table 9 reveals the effects of ‘‘spillovers’’ over different productivitycomponents in association with other factors such as market concentrationor R&D. For example, it can be seen how the interaction between marketconcentration and spillovers has a negative and statistically significant effecton TEC and (G0). Along the same lines, the interaction between R&D activityand spillovers has a negative and statistically significant effect on SEC. Thenegative and statistically significant estimate of the interacting variablebetween spillover and R&D effort indicates that firms with high R&D efforttend to gain less technological spillovers on SEC. The estimate for aninteracting variable between spillover and concentration is negative andstatistically significant, suggesting that competition is associated with higherspillovers on TP, TEC, and G0.

DISCUSSION

At least two reasons make Chile an interesting case study: First, because from1994 to 2007 the country’s average rate of economic growth was close to 5%,with most of this growth experienced in the decade before 1994. ExaminingChile is also relevant due to its relative importance in the subcontinent. Infact, most of the economic variables have presented good behavior (inflation,public deficit, external balance, finances, etc.). In this sense, this economyappears to be an excellent candidate to test the hypothesis concerning theexistence of productivity spillovers in the manufacturing sector because ofFDI. This study examines the productivity spillovers from FDI in the Chileanindustrial sector by using unique and extensive firm-level panel data cover-ing 2001–2003. This article uses the stochastic frontier production functionfollowing the technique used by Battese and Coelli (1995) and a generalizedMalmquist output-oriented index to decompose productivity growth.

The intra-industry productivity spillovers are examined through thespillover variable, and the roles of competition and R&D in extending spil-lovers from FDI are evaluated to test a channel of productivity spillovers.The empirical results show that intra-industry productivity spillovers arepresent in the Chilean industrial sector. Firms with R&D expenditure receivemore productivity spillovers than those without R&D expenditure. These find-ings support our second hypothesis H2 and, in line with works by Girma andcolleagues (2006) for the Chinese industry, we can add empirical evidencethat Chilean firms that invest in R&D have positive FDI spillovers. Results alsoshow that technological progress is the major driver of productivity growth inthe Chilean industrial firms. FDI spillovers have been found to be positive butnot significant for scale efficiency change, technological progress change,technical efficiency change, and total productivity growth change.

In addition to the empirical evidence found, we think that the maincontribution of our study is to have applied a parametric methodology,which allows performing robust estimates and using the firm as the unit ofanalysis. We believe that the limited empirical literature on this topic in thecontext of Latin America and the Caribbean gives value to this work.

On the other hand, the main limitation of this work stems from restricteddata. This circumstance makes it necessary to be cautious with the results, butalso opens the door to future studies that use other methodologies based ondynamic panel models. (See, for example, Arellano & Bond, 1991; Arellano &Bover, 1995; Bover & Arellano, 1997; Blundell & Bond, 1998.) These meth-odologies allow the use of time series with a number of shorter periods andset multiple lagged endogenous variables among the explanatory variables.Alternatively, albeit less robust, possibly helpful in validating our results isthe use of nonparametric techniques to assess efficiency and productivity.

Policy Implications

Despite the presence of positive spillovers from FDI, the policy implicationsof these findings are not straightforward. However, certain policy reflectionsdo follow from the findings. The findings of positive productivity spillovers atthe aggregated manufacturing level suggest that the government should con-tinue to provide FDI-friendly environment and deregulation policies relatedto FDI. This could include simplifying the administrative processes for FDIinflows, additional incentives for foreign firms that are willing to transfer theirknowledge to domestic firms, and further trade policy reforms to promote amore competitive environment in the manufacturing sector. Outcomes fromthe decomposition analysis suggest that incentives should be provided to FDIthat generate advanced managerial knowledge as well as those that provideup-to-date technology transfer. Results suggest the importance of improvingthe capacity of domestic firms in order to update the spillover benefits fromFDI. For instance, it is worth noting that Salim and Bloch (2009) suggestedthat policies for strengthening the absorptive capacity of domestic firmsthrough investing in knowledge and human capital formation might besuperior to policies that provide concessions for FDI.

Preferential policies that solely consist of opening up some selectedregions are not optimal for Chile. In order to reap more benefits from foreignpresence, coordinated industrial policies that reinforce regional comple-mentarities are needed. In addition, the removal of restrictions to the freemovement of production factors across regional borders appears to becrucial to improve productivity levels.

Such policies also reveal the importance of controlling for those localcapacities related to the macroeconomic and institutional environment. Thus,host country governments should develop a set of policies that are notonly focused on inward FDI promotion but also on the improvement of their

political and economic framework. According to Alguacil, Cuadros, and Orts(2011), more general policies such as building modern infrastructure orincreasing and strengthening the institutions should be pursued, which notonly attract FDI but also benefit domestic firms.

APPENDIX ADETERMINISTIC FRONTIER PRODUCTION FUNCTIONS:THE STOCHASTIC FRONTIER-INEFFICIENCY MODEL

The approaches linked to the analysis of the productivity are well known: onone hand, we have a descendent vision of the analysis of the productivityassociated with the concept of residual factor that this tied to the questionsraised by Solow in his well-known article of 1957. On the other hand, we havean ascending approach that attempts a measurement of the productivity froma heterogeneity that is inherent to the different production units (companies).

This work line finds its basis in the pioneer works of Farrel, whosearched for a measurement of the efficiency through the decompositionof the productivity’s growth. Both approaches have resulted in multipleworks and important technical developments that allow, in one way oranother, one to get to know the bases on which the change in productivityof the factors stand.

Following Battese and Coelli (1995), the stochastic frontier approachis used to estimate a production function and an inefficiency functionsimultaneously. The Battese–Coelli model can be expressed as follows:

yit ¼ f xit; t; bð Þ � exp vit � uitð Þ ð1Þ

where yit implies the production of the ith firm (i¼ 1, 2, . . . , N) in the tthperiod (t¼ 1, 2, . . . , T), xit denotes a (1� k) vector of explanatory variables,and b represents the (k� 1) vector of parameters to be estimated. The errorterm consists of two components: vit and uit, which are independent of eachother. In addition, the vit denotes the time-specific and stochastic part, withidd N 0;r2v

� �, and the uit represents technical inefficiency, which is normal

distribution, but truncated at zero with mean zitd and variance r2u.The technical inefficiency effects, uit, are assumed as a function of a

(1� j) vector of observable nonstochastic explanatory variables, zit, and a(j� 1) vector of unknown parameters to be estimated, d. In a linear equation,the technical inefficiency effects can be specified as follows:

uit ¼ zitdþ wit ð2Þ

where wit is an unobservable random variable, which is defined by thetruncation of the normal distribution with zero mean and variance, r2u, suchthat the point of truncation is �zitd.

Equation (1) shows the stochastic production function in terms of theoriginal production value, and Equation (2) represents the technical inef-ficiency effects. The parameters of both equations can be estimated simul-taneously by the maximum-likelihood method. The likelihood function isexpressed in terms of variance parameters r2s � r2v þ r2u and c � r2u=r

2s e. If

c equals zero, then the model reduces to a traditional mean response functionin which zit can be directly included into the production function.

Based on the theoretical model in Equations (1) and (2), we start with aflexible functional form, namely, a translog production function. By adoptinga flexible functional form, the risk of errors in the model specification can bereduced. Moreover, the translog form is useful for decomposing the totalfactor productivity growth. The functional form of the translog productionfunction is as follows:

APPENDIX BDECOMPOSING PRODUCTIVITY GROWTH:

A GENERALIZED MALMQUIST INDEX

According to Orea (2002), if firm i’s technology in time t can be representedby a translog output-oriented distance function D0(yit, xit, t) where yit, xit, andt are defined previously, then the logarithm of a generalized output-orientedMalmquist productivity growth index, Gt;tþ1

Given the technical efficiency measure in Equation (5), the technicalefficiency change between periods tþ 1 and t can be estimated by followingCoelli and colleagues (2005):

TECt;tþ1i ¼ ln TEi;tþ1 � ln TEit ð8Þ

The technical progress index can be obtained from Equations (6), (9),and (11) as follows:
