The objectives of this article are to illustrate theoretically and empirically how to incorporate an <italic>ad valorem</italic> tariff in spatial equilibrium models and show the equivalence of three approaches (primal, dual and MCP) of spatial equilibrium trade modelling. The article lays out in detail the...

We implement a neoclassical growth model that incorporates investment-specific technology (IST) modifying capital investment in the law of motion of capital and bifurcates productivity into human capital and total factor productivity (TFP) in the production function. We focus on the role of...

This paper develops an econometric model of stochastic production functions to quantify the impacts of climatic variables on the mean, variance, and covariance of crop yields. The estimates of the production function parameters and their elasticities are utilized to analyse the impacts of the...

Since 1950s India has advocated import substituting industrialization policies to promote its manufacturing sector. The end result was creation of a dual economy: highly favored manufacturing sector with high and rigid wages and neglected agricultural sector with low wages and poverty. Because...

Since a few countries produce most of the world's wheat, and consumption is widespread across the world, wheat is one of the most commonly traded agricultural commodities. In recent years, the wheat market has been going through difficult phases as wheat prices are depressed. The fall in wheat...

In April 2000, India eliminated the quantitative import restriction of apples and instituted a trade barrier in the form of lower ad valorem tariffs. This study examines the impacts of Indian trade policies on the apple market by reviewing the government policies, discussing mathematical and...

This study develops a world spatial equilibrium softwood lumber model comprised of the major importing and exporting countries/regions to analyse the impacts of global trade reform on the world softwood lumber market. The results show that free trade leads to an increase in lumber trade, and...

This study computes technical efficiency for Idaho sugarbeet farms and decomposes it into pure technical efficiency, scale efficiency, and congestion efficiency using nonparametric procedures. The results indicate that the average efficiency is 0.88 with 45% of the farms in the sample exhibiting...

Apples are the third most valuable fruit in the United States and account for 18% of US fruit exports. Chile is a major competitor to the United States in the MERCOSUR market, since it is one of the leading apple producing countries and enjoys the tariff reductions as a member of MERCOSUR....

This study demonstrates the crucial role the specification of the cost function plays in identifying the market power parameter in autarky models. For constant marginal cost or marginal cost with quantity interacting with input prices, the market power parameter in autarky models in identified...
