Abstract:

These data are a subset created by the ICPSR from the Direction of Trade (DOT) dataset prepared and distributed by the International Monetary Fund. They consist of only the annual time series on the distribution of all countries' exports and imports by partner countries. Data are provided for 220 countries and geographical areas, with the earliest entries beginning in 1948. The time series include data estimates derived from the reports of partner countries for non-reporting and slow-reporting countries. All series are expressed in millions of U.S. dollars. Data originally reported in national currencies are converted by the IMF with the exchange rates (line rf) published in the IMF's International Financial Statistics. All exports are valued f.o.b. and all imports c.i.f. (with a 10 percent adjustment for those countries reporting imports f.o.b.). The data are ordered by ascending subject country code (V1) and within each country they are grouped by trade code (V3), first exports, then imports. Within each trade type the time series are organized by ascending partner country code (V2). Each time series, or subject country/trade type/partner country combination, is a single case. For example, the data potentially contain each of the following four cases: 1) exports from Canada to France, 2) imports by Canada from France, 3) imports by France from Canada, and 4) exports from France to Canada. Every pair of countries, however, may not always have four entries. The user should also note that countries have data covering a variety of time spans with the maximum span being 1948-1978. Note that while sometimes series begin in 1948, other may begin as late as 1970. User's should consult the IMF's Direction of Trade publication if they wish to determine which data have been derived from partner country data. See Direction of Trade, International Monetary Fund, Washington, D.C., March 1979.

Kind of Data:

AGGREGATE DATA

Notes:

The term ''country,'' as used in this dataset, does not in all cases refer to a territorial entity that is a state as understood by international law and practice. The term also covers some territorial entities that are not states but for which statistical data are maintained and provided internationally on a separate and independent basis.

Methodology and Processing

Time Method:

time-series

Data Collector:

International Monetary Fund

Frequency of Data Collection:

yearly

Sources Statement

Data Sources:

Central bank reports and bulletins, IMF area departments, Organization for Economic Cooperation and Development, International Labor Organization, IMF Treasurer's Department, the United Nations, the National Bureau of Economic Research, and information from national authorities.

Cleaning Operations:

In preparing this subset of annual time series from the DOT dataset the ICPSR converted the data from zoned decimal storage mode to standard character numeric storage mode. The original zoned decimal version of these data which contains monthly and quarterly data in addition to the annual data continues to be available from ICPSR. This version, as obtained from the IMF, requires the use of a special COBOL processing program, which ICPSR supplies, on a special program written by the user. These data were processed for ICPSR distribution by B. Ruth Montgomery and William K. Domke.

Data Access

Location:

Citation Requirement:

Publications based on ICPSR data collections should acknowledge those sources by means of bibliographic citations. To ensure that such source attributions are captured for social science bibliographic utilities, citations must appear in footnotes or in the reference section of publications. The bibliographic citation for this data collection is: International Monetary Fund. DIRECTION OF TRADE, 1948-1978 [Computer file]. 1st ICPSR Ed. Ann Arbor, MI: Inter- university Consortium for Political and Social Research [producer and distributor], 1979.

Deposit Requirement:

To provide funding agencies with essential information about use of archival resources and to facilitate the exchange of information about ICPSR participants' research activities, users of ICPSR data are requested to send to ICPSR bibliographic citations for each completed manuscript or thesis abstract. Please indicate in a cover letter which data were used.

Disclaimer:

The original collector of the data, ICPSR, and the relevant funding agency bear no responsibility for uses of this collection or for interpretations or inferences based upon such uses.

File Description--CARD-IMAGE

File: da7628s.gz

  • File Structure: rectangular

  • Number of cases: 40,026

  • No. of variables per record: 37

  • Logical Record Length: 80

  • Records per Case: 4

  • Overall Number of Records: 160,104

  • Type of File: raw data

  • Data Format: card-image  (link)

Notes:

The card-image file contains 4 decks per case in a format based on 80-column punched cards. Each case consists of a subject country/trade type/partner country combination (e.g., exports from Canada to France is one case, imports by Canada from France is another, and imports by France from Canada is yet another). The data are sorted with subject country (V1) as the major sort field, trade code (V3) as the second sort field, and partner country (V2) as the third sort field. In the card-image file all decks for each case are together in ascending order.

Notes:

There are two components in the OSIRIS dataset: the OSIRIS dictionary and the OSIRIS data file. The OSIRIS dictionary gives the variable name and number, tape location, width, and missing data values for each variable in the OSIRIS data file. The dictionary is used in conjunction with the OSIRIS software package. The OSIRIS data file has a logical record length of 230 characters. It can also be accessed directly by software packages which do not use the OSIRIS dictionary by specifying the tape locations for the desired variables.

Notes: Variables V5-V35, identify the amount of trade that occurred between the subject country (V1) and its partner country (V2) in the year specified by the variable name. The trade amounts are always given in Millions of U.S. Dollars and decimal places are as specified in Variable 4. Variable 3, TRADE CODE, identifies whether the data are for the yearly total of exports from the subject country to the partner country, or for the yearly total of imports by the subject country from the partner country. Each datum is seven columns wide with the first column allocated for the algebraic sign. Positive numbers are assumed unless a quotation mark sign is given in the first column.
