Natural and agricultural resources for which there is a substantial black market, such as coca, opium, and diamonds, appear especially likely to be exploited by the parties to a civil conflict. On the other hand, these resources may also provide one of the few reliable sources of income in the...

Transport costs play a key role in agricultural markets in developing countries and are one of the causes of poverty amongst farmers that are geographically isolated. Another characteristic of agricultural markets is that they often involve interlinked transactions. However, the existing...

We use a North-South model with property right differences and resource dynamics to study the effects of trade on resource use and welfare. Autarky is likely to Pareto-dominate free trade in the long run when the environment is quite fragile, and the result is reversed when the environment is...

This paper estimates a structural model of economic geography using cross-country data on per capita income, bilateral trade, and the relative price of manufacturing goods. More than 70% of the variation in per capita income can be explained by the geography of access to markets and to sources...

Gender-based discrimination is a pervasive and costly phenomenon. To a greater or lesser extent, all economies present a gender wage gap, associated with lower female labour force participation rates and higher fertility. This paper presents a growth model where saving, fertility and labour...

We propose a market-for-offenses model of property crime, which explicitly accounts for protection expenditures among heterogeneous individuals. The crime equilibrium is modeled as a free-access equilibrium in which the match between criminals and victims equates the average returns to crime. We...

A new round of WTO negotiations on agriculture, services and perhaps some other issues is expected to be launched in late 1999. To what extent should those negotiations include so-called "new trade agenda" items aimed at ensuring that domestic regulatory policies do not discriminate against...

The industrialization of labour is the main engine of growth during the early stages of economic development. In less developed countries, equipment investment has played a less important role than non-equipment investment; and it has only proved growth enhancing when it either encountered a...

In the late 1980s many developing countries experienced something of a paradigm shift, in that governments began to pursue more market oriented domestic policies. There was increasingly a perception that liberalizing access to service markets was a potentially low cost and effective method of...

This paper reviews the empirical evidence on the relationship between economic output and various dimensions of air and water quality. Pollution may rise with growth, because an increased scale of economic activity means more emissions, ceteris paribus. Economic growth may be associated with a...
