The purpose of
having multiple data sources readily available and easily
accessible is to further research on the microeconomic foundations
of the macro economy, that is, to develop microeconomic and
macroeconomic models, ideally combining the two. Specifically,
these data can be used to construct and estimate general equilibrium
models with impediments to trade and with heterogeneity across
households and firms. The user can choose the appropriate
degree of aggregation of the microeconomic data, or go back
and forth between micro and macro. Indeed, this archive facilitates
fact-finding missions. Several of the individual databases
have automated search and data extraction facilities. Several
of the microdata files include geographic identifiers at the
plot, village, sub-county (tambon), county (amphoe), or province
(changwat) level, thus enabling use of an accompanying
Geographic
Information System.
The larger goal
of this web-based archive is to facilitate the integration
of theory with measurement. Frequently the data a theorist
might need to calibrate or estimate a model is not available
in the single database on hand, hence the inclusion of multiple
databases here. Frequently, the necessary data are not available
at all. That is, existing surveys do not include variables
critical to theoretical models. For example, until recently,
there were no longitudinal data for Thailand. A key component
of this website is a panel database derived from micro surveys
designed from a theoretical perspective. This collection,
know as the
Townsend
Thai Project, is available from this site. The other databases
Related Thai
data are also available.
The project was
funded primarily by US government foundations, specifically,
the National Institute of Health (NICHD) and the National
Science Foundation (NSF), with Robert M. Townsend as principal
investigator. Grants from the Ford Foundation, Melon
Foundati on and the University of Chicago are also gratefully
acknowledged.
Papers
and publications that use the data available in this archive
and describe the details of the models are also available
from this site, along with professional abstracts and executive
summaries for policy makers. Additionally, a
Theoretical
Overview is available.
