Balance of payments (BOP) – responsibility of LB since 2000

Foreign investments business survey – carried out by LB since 2001

Balance of payments

• In economics, the balance of payments (BOP) measures the payments that flow between any individual country and all other countries.

• It is used to summarize all international economic transactions for that country during a specific time period, usually a year.

• The BOP is determined by the country's exports and imports of goods, services, and financial capital, as well as financial transfers.

• It reflects all payments and liabilities to foreigners (debits) and all payments and obligations received from foreigners (credits).

• Balance of payments is one of the major indicators of a country's status in international trade, with net capital outflow

• (From Wikipedia, the free encyclopedia).

Quarterly and annual by BOPSY codes (by positions used in the IMF

balance of payments statistics yearbook), by country, by type of industry (NACE code) Monthly only few main positions (mainly for

internal use) IIP by country, by type of industry

Balance of payments compiled at LB

companies MFI statistics statistics on non-bank external payments (ITRS)

Financial and Capital Market Commission aggregated data on investment in banks’ share capital aggregated data on banks’ annual profit/loss and its

distribution

Quarterly business survey on foreign investment – data collected

Data source for FDI, portfolio investments, other investments and related accrued income flows of other sectors

Divided in three parts – FDI in Latvia, FDI abroad, other foreign assets and liabilities

Country breakdown

Full reconciliation of positions and changes in positions reflecting net flows, price changes, exchange rate changes and other adjustments

8

Quarterly survey on foreign investment – sampling frame

Stratified simple random sampling is used

The sampling frame is built up using: Quarterly survey data of the previous year State Register of Enterprises Information obtained from the CSB ITRS data Annual survey data on foreign investment Other sources (mass media, etc.)

The sampling frame is updated annually just before sampling (significant changes discovered during the survey year are updated as soon as they have been identified)

9

Quarterly survey on foreign investment – stratification

The activity indicator is calculated for each company in accordance with the BOPSY breakdown by taking the max transactions value either from the survey or ITRS data for the previous year

The companies are arranged in a descending order according to the activity indicator and divided into size groups

The target population is further stratified depending on the company’s NACE

10

Quarterly survey on foreign investment – sample allocation

The Neyman’s optimum allocation over strata according to the activity indicator is determined

Some adjustments in the sample allocation are made to reach satisfaction quality demands for main domains of interest

Within each stratum the list of companies to be included in the sample is drawn by using the simple random sampling approach

11

Quarterly survey on foreign investment – dealing with non-response

Reminders by phone allow to reach near to 100% of response rate among the significant units

Response rate ~95%

Dealing with non-response Big units: imputation based on survey data on

previous periods + ITRS data (case by case) Other units: adjustment of weights

Response level, 4th quarter, 2008

Quarterly survey - estimation

HT estimates for totals Unweighted survey data are used for country and

NACE breakdown Grossing up part of the survey data to the whole

population is showed as “Country not specified” and “Kind of activity not classified” in output tables by country and by NACE breakdown

Annual survey on foreign investment – why needed?

Sample design and the total sample size of the quarterly survey allows to reach the necessary quality of estimates anly for flows (and not for stocks). Therefore additional annual sample survey on foreign investments is carried out

From units not included in the sample of the quarterly survey another stratified simple random sample is taken as a sample for annual survey on foreign investment. Sampled companies are surveyed using a simplified questionnaire

15

Annual survey on foreign investment – usage of data

Data of the annual survey are used for:

Production of high quality estimates of IIP annual positions of other sectors

Production (by combining of the annual IIP estimates with the estimates of quarterly flows) of quarterly estimates of IIP positions of other sectors at the end of quarters

Updating of the quarterly sampling frame

16

Usage of ITRS data

Data source for compilation of the monthly BoP

As a supplementary data source For building of the sampling frame of the

quarterly survey of foreign investments Updating of the sampling frame during the

survey year For cleaning of quarterly survey data For imputation

17

Dissemination of data

Monthly – T+30 business days

Quarterly – last business day of the next quarter FDI flows and positions by:

• country• kind of activity by country• inflow and outflow components
