The author examines whether trade liberalization should create a greater incentive for countries to invest in transportation infrastructure. He pays special attention to the case of preferential trade liberalization between neighboring countries, where investments in roads or railroads are...

The combination of distance, poor infrastructure, and being landlocked by neighbors with poor infrastructure, can make transport costs many times higher for some developing countries than for most others. Drawing on two traditions of economic modeling --Heckscher-Ohlin trade theory and von...

Although it is commonly believed that aggregate economic growth must be associated with public infrastructure stocks, the possible infrastructure needs and effects are different from industry to industry. The agriculture sector is typical. Various infrastructures would affect agriculture growth...

Argentina is one of the world's largest biodiesel producers and the largest exporter, using soybeans as feedstock. Using a computable general equilibrium model that explicitly represents the biofuel industry, this study carries out several simulations on two sets of issues: (i) international...

The paper identifies the impact of physical barriers to trade within Central America through the use of an augmented and partially constrained Gravity Model of Trade. Adjusting the Euclidian distance factor for Central America by real average transport times, the model quantifies the impact of...

The paper proposes a modification of Baulch's parity bounds model to measure the market integration of food markets in developing countries. Instead of extrapolating a single observation of transaction costs, it estimates transaction costs. Predicted transaction costs compare well with survey...

Numbers ranging from half a trillion to two trillion dollars have been cited in recent years for global subsidies for fossil fuels. How are these figures calculated and why are they so different? The most commonly used methods for measuring subsidies are the price-gap approach -- quantifying the...

"Getting the prices right"is a good starting point but is not sufficient for achieving environmentally efficient outcomes. Other policy interventions are often necessary to complement pricing policies. Moreover, when pricing is not at all feasible, regulatory and command-and-control policies...

This paper analyzes the scale and productivity consequences of varied input use in Indian manufacturing using detailed plant-level data. Counts of distinct material inputs are higher in urban settings than in rural locations, unconditionally and conditional on plant size, and they are also...

Inappropriate regulation can influence productivity performance by affecting incentives to invest and adopt new technologies, as well as by directly curbing competitive pressures. Results of a labor productivity growth model for European countries suggest that improving the regulatory...
