Protection For Sale Under Monopolistic Competition: An Empirical Investigation, Pao Li Chang, Myoung-Jae Lee Aug 2006

Protection For Sale Under Monopolistic Competition: An Empirical Investigation, Pao Li Chang, Myoung-Jae Lee

Research Collection School Of Economics

This paper proposes a general empirical framework to estimate the protection-for-sale model, where the protection regime shifts according to a sector's market structure (perfectly or monopolistically competitive). We base the protection structure on Grossman and Helpman (1994) for the subset of perfectly competitive sectors and on Chang (2005) for the subset of monopolistically competitive sectors. The two protection regimes are simultaneously estimated with joint constraints. The results of the J-test consistently reject the homogeneous (perfect competition) protection-for-sale model often adopted in previous literature and suggest a direction of improvement toward the proposed heterogeneous protection structure model.


Green Revolutions And Miracle Economies: Agricultural Innovation, Trade And Growth, Brishti Guha Jun 2006

Green Revolutions And Miracle Economies: Agricultural Innovation, Trade And Growth, Brishti Guha

Research Collection School Of Economics

The purpose of this paper is to develop a simple model of an economy in which growth is driven by a combination of exogenous technical change in agriculture and a rising world demand for labor-intensive manufactured exports. We explore the relative roles of an exogenous agricultural productivity shock and rising export demand in a model with two traded industrial goods and a non-traded agricultural good, food. When the non-traded sector uses a specific factor, we show that technical change in agriculture may be the key to factor migration into industry, in particular driving intersectoral labor migration. A key assumption is ...
