This research explores the origins of the distribution of time preference across regions. It advances the hypothesis, and establishes empirically, that geographical variations in natural land productivity and their impact on the return to agricultural investment have had a persistent effect on...

Why do developing countries fail to specialize in products in which they appear to have a comparative advantage? We propose a model of agricultural trade with intermediation that explains how hold-up resulting from poor contracting environments can produce such an outcome. We use the model to...

A large agronomic literature models the implications of climate change for a variety of crops and locations around the world. The goal of the present paper is to quantify the macro-level consequences of these micro-level shocks. Using an extremely rich micro-level dataset that contains...

We study the effects of globalization on agricultural productivity across countries. We develop a multi-country general equilibrium model that incorporates choices of crops and technologies in agricultural production at the micro-level of fields covering the surface of the earth. We estimate our...

This paper examines interactions between market power and agricultural policy in the U.S. wheat flour milling industry using a non-parametric approach. The analysis focuses on marketing loan and pre-1986 deficiency payment programs; farmers' payments from these programs are dependent on whether...

Grain shippers and political figures in North Dakota and nearby states have voiced concern that the dramatic increases in shipments of crude oil by rail have caused service delays and higher costs. We investigate the potential impact of crude shipments on grain markets accounting for harvest...

In this paper we develop a new approach to measuring the gains from economic integration based on a generalization of the Ricardian model in which heterogeneous factors of production are allocated to multiple sectors in multiple local markets based on comparative advantage. We implement this...

This paper evaluates the influence of diverse U.S. agricultural interest groups on the North American Free Trade Agreement (NAFTA). Under NAFTA, licenses and quotas that restricted agricultural trade between Mexico and the United States were converted to tariffs in January 1994 and all tariffs...

This paper explores the role of export costs in the process of poverty reduction in rural Africa. We claim that the marketing costs that emerge when the commercialization of export crops requires intermediaries can lead to lower participation into export cropping and, thus, to higher poverty. We...

Starting with Romer [1987] and Rivera-Batiz-Romer [1991] economists have been able to model how trade enhances growth through the creation and import of new varieties. In this framework, international trade increases economic output through two channels. First, trade raises productivity levels...
