As the pipeline of new biotech crops has continued to expand, regulatory approvals of such crops across different countries have become less synchronized. As a result, some biotech crops can be cultivated in one or more countries but may not be approved for use in others. Under such...

County-level yield data are used in applied research and crop insurance policy in place of farmlevel yield data, which are likely sparse, not broadly representative, and subject to selection bias. We exploit the fact that county-level yields are the aggregate of farm-level yields to derive...

The topic of this paper is the relationship between relative income and health. We examine whether people whose incomes are high relative to others who live in the same geographic area have lower or higher mortality. This analysis holds own income fixed, so the question is not only whether own...

Parametric stochastic frontier models have a long history in applied production eco- nomics, but the class of tractible parametric models is relatively small. Consequently, researchers have recently considered nonparametric alternatives such as kernel den- sity estimators, functional...

Conditional Markov chain models of observed aggregate sharetype data have been used by economic researchers for several years, but the classes of models commonly used in practice are often criticized as being purely ad hoc because they are not derived from microbehavioral foundations. The...
