MotivationEmerging markets are enlarging their participation in world GDP and trade, especially BRICS.
Some of them have financial institutions to provide long term loans.
BRICS are not exception to this rule (all have at least one)
Brazilian Government provide those long term loans through its Brazilian Development Bank (BNDES).
BNDES mandatory goal is to burst Brazilian economy without neglecting social aspects.
Therefore, it is important to evaluate whether their financial support has been able to improve firms’ competitiveness, which will be measured by productivity.
Why productivity?
“Productivity isn’t everything, but in the long run it is
almost everything. ..... Compared with the problem of slow
productivity growth, all other long-term economic
concerns - foreign competition, the industrial base, lagging
technology, deteriorating infrastructure and so on - are
minor issues”
(Krugman, 1992)
Asumption:
In order to implement one project, firms decide on whether using:
1. Old (Low) Technology – lower fixed cost, but higher marginal cost
2. New (High) Technology – higher fixed cost, but lower marginal cost
According to our model, credit constraints might affect those two fixed costs asymmetrically.
1. If it is more towards new technology, productivity increases.
2. If it is towards old technology, productivity reduces.
3. If it affects them symmetrically, productivity remains constant
Theoretical Foundation
BNDES finances different types of firms, from micro to multinationals.
In 2009, its disbursements reached US$ 78 billion (representing 13,3% of aggregate investment).
We investigate two types of loans:
1. FINEM (direct – over US$ 5 millions);
2. Automatic BNDES (indirect – below this threshold);
Both cover: creation of new plants; enlargement of existing ones; restructuring and modernization of processes; and
innovation and technological development
Why BNDES?
• From 1995 to 2007, 9,828 firms were granted one of these loans;
• These two loans represents around 40% of BNDES resources.
Some figures
Using different data sources,
some firms are discarded:
• Too small (no information in main data source where we measured productivity);
• If two firms merge, the loan will be registered to the new company, which didn’t exist before when there is the information;
• There is a time-lag for a firm to take part in the survey.
Empirical Strategy
1. Choosing treated group (1995 to 2007)
a. Previous Period to find a reasonable counterfactual group
b. Post Period to evaluate impact
2. Finding counterfactual groups by PSM or by other method.
3. Verify whether treated firms perform differently from non-treated firms.
4. Estimating by Naive Model (OLS) and Sophisticated Model (Dif-in-Dif) governments’ impact.

Main Results from Econometrics
Control Groups or Counterfactual Groups
a) Firms which have survived and invested (6 thousand firms)b) Firms first granted in 2007c) Paired Firms using PSM
Regardless which control group is considered, results are the same.
1. Naive Model (OLS)• Labour Productivity - Positive• Total Factor Productivity - Negative
• Sophisticated Model (Difference-in-Differences)a) Non Significant Results
Main Conclusions
BNDES Loans might be able to relax credit constraintsHowever, it seems that it is not impacting productivity
Reasons:
1. Projects selected might not be the most prominent
2. Loans may be reducing implementation costs for both old and new technology projects symmetrically, therefore not impacting average firms’ productivity
Increase number of manufacturing firms in Brazil from 20 thousand to more than 40 thousand during 1996 to 2006.
