Economic Impacts of Improved Connectivity for ASEAN: An Application of the Geographical Simulation Model

We compare the prioritized projects of the Master Plan on ASEAN Connectivity (MPAC) and the Comprehensive Asia Development Plan (CADP) by utilizing the Institute of Developing Economies/Economic Research Institute for ASEAN and East Asia Geographical Simulation Model. The prioritized projects of the MPAC mainly focus on specific hard or soft infrastructure projects connecting one remote area of an ASEAN member state to another and thus fail to capture the full potential of the infrastructure because of neglected important links within a state. On the other hand, the CADP emphasizes the importance of economic corridors or linkages between a large cluster and another cluster. Our simulation analysis shows that CADP projects will result in an addition to gross domestic product (GDP) of

AGGLOMERATION AND DISPERSION IN CHINA AND ASEAN: A GEOGRAPHICAL SIMULATION ANALYSIS

US 1544bn over the period from 2021 to 2030 (in 2010 dollars) or an impact on ASEAN countries that is 12 times larger than MPAC projects. The results strongly suggest that the CADP projects should be adopted and implemented to fully realize the potential economic growth of the ASEAN countries. Moreover, the CADP will contribute more to narrowing the development gaps among the ASEAN countries than MPAC prioritized projects.

Long-Run Economic Impacts of Thai Flooding on Markets and Production Networks: Geographical Simulation Analysis

Spatial designing of economic development with enhancing connectivity has become essential to pursue both sustained growth and the narrowing of development gaps. The issue of agglomeration and dispersion in China and its neighboring countries is an example of requiring such an approach. This paper introduces the Geographical Simulation Model (GSM) based on the new economic geography setting and presents illustrative simulations on Asian Highway No. 3 and Kyaukpyu deep sea port development in order to analyze the economic implication of developing hard and soft infrastructure as well as lowering national border barriers for inclusive growth at the sub-national level.

Geographical simulation analysis for logistics enhancement in Asia

We discuss the long-run economic impact of natural disasters on affected countries by examining the case of flooding in Thailand in 2011. If the damage caused by disasters is really serious, industries will move out from the countries in question, and this outflow leads to a negative impact on the national economies in the long run. By using IDE/ERIA-GSM modeling and utilizing short-run forecasts for the basic setting, we estimate the seriousness of the flooding in terms of the long-term economic performance. Simulation results show that negative long-run impacts of the flood will likely be moderate as many companies’ first reaction to the flood was to seek possible relocation of their production sites within Thailand.
