Neutrality in the choice of number of firms or level of fixed costs in calibrating an Armington-Krugman-Melitz encompassing module for applied general equilibrium models

This paper shows how an Armington-Krugman-Melitz encompassing module based on Dixon and Rimmer (2012) can be calibrated, and clarifies the choice of initial levels for two kinds of number of firms, or parameter values for two kinds of fixed costs, that enter a Melitz-type specification can be set freely to any preferred value, just as the cases we derive quantities from given value data assuming some of the initial prices to be unity. In consequence, only one kind of additional information, which is on the shape parameter related to productivity, just is required in order to incorporate Melitz-type monopolistic competition and heterogeneous firms into a standard applied general equilibrium model. To be a Krugman-type, nothing is needed. This enables model builders in applied economics to fully enjoy the featured properties of the theoretical models invented by Krugman (1980) and Melitz (2003) in practical policy simulations at low cost.

Trade obstacles, inventory level of inputs, and internationalization of enterprise activities : a comparison between Southeast Asia and Latin America

This paper investigates the impact of trade barriers such as customs clearance, subjective trade obstacles (customs and trade regulations), and inventory of inputs on the internationalization of enterprises in Southeast Asia and Latin America, using the World Bank's enterprise surveys. Empirical results show a negative association between the internationalization of enterprises and subjective trade obstacles, while the impact of subjective trade obstacles is not significant on enterprises already internationalized. An international comparison between Southeast Asia and Latin America suggests that enterprises in Latin America face unfavorable conditions that discourage them from becoming more closely inserted into international production networks.

Service liberalization in Lao PDR

Service liberalization is emerging as a high-priority issue in various parts of the world for mega free trade agreements as well as national policy. Lao PDR is no exception. To examine the level of service liberalization in Lao PDR, we first compare the Hoekman Indices of Lao PDR, Cambodia, and Vietnam on the ASEAN Framework Agreement on Services (AFAS 8). Lao PDR has lower commitment in many subsectors. In particular, we list the sectors in which Lao PDR made a lower commitment than Cambodia and Vietnam in Mode 3 (supply of services through commercial establishments abroad). Second, a simulation analysis using the Geographical Simulation Model (IDE-GSM) from the Institute of Developing Economies at the Japan External Trade Organization (IDE-JETRO) reveals how service liberalization benefits the economic development of Lao PDR. The two analyses clearly reveal that it is essential for Lao PDR to promote further service liberalization since such liberalization will contribute to the country's development.
