Investments in technology have yielded large gains for agriculture, and the benefits have been passed on to consumers in the form of lower prices. Thus history justifies public spending on agricultural research.A comprehensive examination of data from many countries shows that in 1967-92, 81...

A comprehensive examination of data from many countries shows that in 1967-92, eighty-one percent of the world's population lived in countries where agricultural growth exceeded population growth. Moreover, that growth occurred as agricultural prices declined. Productivity gains are a dominant...

This report is part of an attempt to model the global markets for primary commodities and to use these models for forecasting purposes as well as for policy analysis. In a free market, domestic prices on agricultural products could be expected to vary with world prices. But intervention is so...

farm size inequality is a natural outcome of farm specialization and the advantages of scale economies for more successful farmers, but it could weaken the common interests among farmers and thus their political power. This is especially true for farms that are organized in cooperatives, such as...

This paper analyzes the effect of family composition, and in particular the number of children, the age gap between the oldest and youngest child and the age of the youngest child, on parents’ involvement in social networks. The predictions of a simple theoretical model are confirmed by an...

Abstract We develop an empirical framework for evaluating the profitability of the use of barn owls to control rodent populations by locating nesting boxes in agricultural areas. Barn owls’ behavior is incorporated into the analysis by estimated functions that relate agricultural production to...

When a nonpoint source pollution process involves many polluters, each taking his own contribution to aggregate pollution to be negligible, ambient-based policies become ineffective due to lack of strategic interactions between dischargers. We offer a regulation mechanism for this case. The...

Democracy tends to cultivate short-sighted politicians, for whom the horizon extends more or less till next election. This feature gives rise to a discrepancy between the time rate of discount of a country’s polity and the interest rates at which the country borrows. I show how this...

Prior to 1996, Israelis in collective communities (kibbutzim) shared the costs of raising children equally. This paper examines the impact of the privatization of kibbutzim on fertility behavior among members. We find that fertility declined by 6-15 percent following the shift to privatization....

We develop a method to characterize the location as well as the time of approach of optimal steady states in single-state, infinite-horizon, autonomous models. The method is based on a simple function of the state variable which is defined in terms of the model's primitives. The actual...
