  2. TODAY, ONE PART, ONLY • TO UNDERSTAND POVERTY, UNEVEN DEVELOPMENT AND THE POTENTIAL FOR TERRORISM LOCALLY • NEED ECONOMIC MODELS TO UNDERSTAND UNDERLYING FORCES WITH FINE TUNED PREDICTIVE POWER • ASSESS POLICY CHANGE

  3. Data: • Socio-Economic Data: Thai Community Development Department (CDD) biannual census data • More than 3000 villages in four provinces, 1986-1996 • Focus on four Thai provinces specifically chosen to represent a cross-section of Thai economic development: fertile central plains versus poorer northeast- same as Townsend Thai project. Adding South/unrest • Supplemental: GIS spatial data collected from a variety of sources, including a number of Thai government agencies. Also utilized an archive of Landsat satellite imagery from 1979-2004

  4. 1986-1996: Thai high growth period Thai economy experienced some of the highest growth rates in the world, ranging from 7 to 12 percent, often attributed to financial liberalization • Average wealth doubled, rapid industrialization • Extensive deforestation and urbanization

  5. A Satellite View Of Industrialization

  6. Wealth Index Spatial Distribution Chachoengsao, Lop Buri, Buriram and Sisaket 1986-1996

  7. GIS, Road Networks, and “Accessibility”: • Highly detailed geo-referenced data on road networks was used to calculate travel-time along road networks taking into account varying road speeds • This allowed for the creation of variables as proxies for “access” to economic agglomerations, which could then be used in the testing and correction of simulation models

  8. Sisaket Province, - Road Network withAverage Road Speed

  9. Dynamic Simulation of the Occupational Choice Model: • villages as the data points • Simulation begins with base year wealth distribution 1986 and produces results through 1996 • Financial intermediation “index” imposed or not exogenously in each year of the simulation (binary from CDD)- occupation choice and end of period wealth a function of initial and talent (costs) • The credit sector is weighted according to the exogenous intermediation fraction, and an equilibrium obtained giving a common market clearing wage and interest rate in credit mkt • trace path of individual villages given the prices

  10. Spatial and Temporal Testing of the Financial Deepening Model: The simulation did an excellent job of capturing overall dynamic trends

  11. Residuals structural models regressed onto covariates: • Occupation choice onto • wealth, education, an intermediation access and the agglomeration access proxies • Results: • Wealth and education are never significant • However, time-travel to nearest major intersections is positive and significant as model is over predicting with distance • credit intermediation index is positive, as if in the model credit/saving access is too good

  12. An Experiment: • Policy Simulation: create new, hypothetical road networks and impose spatially varying estimated costs via m parameter – • does superior accessibility increase simulated entrepreneurial activity for villages close to new roads? • Roads intersections were created using the GIS according to 2 criteria: • Located far from existing roads and major intersections • Located in areas with low levels of entrepreneurial activity • Model was re-simulated using the spatially modified model (with new estimated m parameter values with distance to new road intersections) • Result: dramatically higher levels of entrepreneurial activity near to the new major road intersections

  13. Financial deepening model • Model over predicts closer to spatial agglomerations • Confirmed with Local Moran spatial statistical cluster detection • Residuals also regressed onto agglomeration proxies, wealth and education, and significant and negative results for all 3 direct agglomeration proxy variables, and significant and positive results for wealth and education • In sum, the simulation is over-predicting close to economic agglomerations- both wealth and credit

  14. Spatial Modification • Again, full sample stratified into bins – 3 bins by equal number of villages – along the axis of time-travel to major intersections • Also, model simulated separately for commercial banks only, and then for BAAC only • This allowed for the estimation across space of the variation in costs of using each major financial provider as captured by the q parameter

  15. Graph above displays relative costs by bin (results plotted in data wealth units) • Note that for BAAC, costs are systematically lower than for commercial banks

  18. Conclusions: • We begin with the assumption that spatial proximity acts to minimize transmission costs for ideas: can we test whether spatial proximity to economic agglomerations facilitates the spread of entrepreneurial activity, wealth or access to credit? • Consequently, we estimate transaction costs as a function of decreasing accessibility to economic agglomerations • For the entrepreneurial choice model, the testing reveals that spatial proximity matters greatly in determining the cost of going into entrepreneurial activities – the model performs much better after estimation of spatially varying entrance costs • For the financial deepening model, the testing reveals an apparently policy distortion due to government support of the public credit provider, resulting in higher estimated costs closer to agglomerations
