Regulatory Protection And The Role Of International Cooperation, Yuan Mei Nov 2023

Regulatory Protection And The Role Of International Cooperation, Yuan Mei

Research Collection School Of Economics

I develop a general equilibrium framework to analyze the welfare consequences of product regulations and their international harmonization. In my model, raising product standards reduces a negative consumption externality, but also increases the marginal and fixed costs of production. When product standards are set noncooperatively, the effects of standards on other countries' wages and number of firms are not internalized, giving rise to an international inefficiency. The World Trade Organization's nondiscrimination principle of national treatment only partly addresses this inefficiency. Welfare losses from abandoning national treatment average 2.8%, whereas the maximum welfare gains from efficient cooperation average 11.8%.


The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang Sep 2020

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang

Research Collection School Of Economics

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.


The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang Sep 2020

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao-Li Chang

Research Collection School Of Economics

This paper characterizes the optimal reciprocal trade policy in the environment of Melitz (2003) with firm productivity heterogeneity. In particular, without making parametric assumptions on firm productivity distribution, this paper derives the optimal degree of reciprocal tariff reductions that maximize the world welfare. A reciprocal import subsidy raises the industry productivity, lowering aggregate price; a reciprocal import tariff helps correct the markup distortion, increasing nominal income. With all the conflicting effects of import tariffs on welfare considered, the optimal degree of reciprocity in multilateral tariff reduction is shown to be free trade.


Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu Apr 2020

Foreign Direct Investment And Industrial Agglomeration: Evidence From China, Wen-Tai Hsu, Yi Lu, Xuan Luo, Lianming Zhu

Research Collection School Of Economics

This paper studies the effect of foreign direct investment (FDI) on industrial ag-glomeration. Using the differential effects of FDI deregulation in 2002 in China on different industries, we find that FDI actually affects industrial agglomeration neg-atively. As FDI brings technological spillovers and various agglomeration benefits, other forces must be at work to drive our empirical finding. We propose a simple theory that FDI may discourage industrial agglomeration due to fiercer competition pressure. We find various evidence on this competition mechanism. We also examine an alternative theory based on spatial political competition, but find no evidence sup-porting it. On industrial growth, …


Competition, Markups, And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu Jan 2019

Competition, Markups, And Gains From Trade: A Quantitative Analysis Of China Between 1995 And 2004, Wen-Tai Hsu, Yi Lu, Guiying Laura Wu

Research Collection School Of Economics

This paper provides a quantitative analysis of gains from trade in a model with head-to-head competition using Chinese firm-level data from Economic Censuses in 1995 and 2004. We find a significant reduction in trade cost during this period, and total gains from such improved openness during this period is 7:1%. The gains are decomposed into a Ricardian component and two pro-competitive ones. The procompetitive effects account for 20% of the total gains. Moreover, the total gains from trade are 13 31% larger than what would result from the formula provided by ACR (Arkolakis, Costinot, and Rodríguez-Clare 2012), which nests a …


Macroeconomic Effects Of Energy Price Shocks On The Business Cycle, Bao Tan Huynh Apr 2016

Macroeconomic Effects Of Energy Price Shocks On The Business Cycle, Bao Tan Huynh

Research Collection School Of Economics

This paper proposes a framework of endogenous energy production with convex costs to investigate the general equilibrium effects of energy price shocks on the business cycle. This framework explicitly models the consumption of durables and nondurables and implements a high complementarity between energy and the usage of durables and capital. The model predicts energy price elasticities of various consumption variables that fall within reasonable agreement with empirical estimates. Convex costs in energy production produce energy price and energy supply dynamics that tallies well with empirical behavior. Our analysis confirms in a theoretical setting recent observations that not all energy price …


Exchange Rates And Export Structure, Wen-Tai Hsu, Yi Lu, Yingke Zhou Sep 2014

Exchange Rates And Export Structure, Wen-Tai Hsu, Yi Lu, Yingke Zhou

Research Collection School Of Economics

This paper studies whether changes in the exchange rate affect a country’s export structure, using an arguably exogenous sudden appreciation of renminbi on July 21, 2005 as the main source of identification. Employing combined regression discontinuity and difference-in-differences approach, we show that China’s export structure became more similar to that of the developed countries after the currency appreciation. We also find that the majority of the appreciation effect comes from the inter-firm resource reallocation rather than the inter-region or intra-firm resource reallocation.


Trade, Firm Selection, And Industrial Agglomeration, Wen-Tai Hsu, Ping Wang Nov 2012

Trade, Firm Selection, And Industrial Agglomeration, Wen-Tai Hsu, Ping Wang

Research Collection School Of Economics

We develop a model of trade and agglomeration that incorporates trade in both intermediate goods and final goods and allows all firms to choose their locations. There are two types of labor: skilled labor, which is mobile, and unskilled labor, which is immobile. Upon choosing its factory site, a final goods firm that is managed by skilled labor can produce these goods using local unskilled labor and a variety of intermediate goods produced by productivity-heterogeneous producers. We characterize world equilibrium and establish the conditions under which industrial agglomeration arises as a stable equilibrium outcome. We show that when the unskilled …
