This paper develops a measure of efficiency when data have been aggregated. Unlike the most commonly used efficiency measures, our estimator handles the heteroskedasticity created by aggregation appropriately. Our estimator is compared to estimators currently used to measure school efficiency....

A Cox nonnested test with parametric bootstrap is developed to select between the linearized version of the First Difference Almost Ideal Demand System (FDAIDS) and the Rotterdam model. The Cox test with parametric bootstrap is expected to be more powerful than the various orthodox tests used in...

This article provides a framework to compare market outcomes among vertically integrated monopsonies in the cotton sector of West Africa and alternative, more competitive market structures. Based on a principal agent framework, in the presence of factor market constraints, as well as capital...

Plant-based precision nitrogen fertilizer application technologies have been developed as a way to predict and precisely meet nitrogen needs. Equipment necessary for precision application of nitrogen, based on sensing of growing wheat plants in late winter, is available commercially, but...

Recent research has found that men trade stocks more frequently than women and receive a lower price as a result. The behavioral finance literature attributes this greater trading activity to men's overconfidence. Women's lack of overconfidence and past agricultural economics research suggest...

Maize ("Zea mays") shortages and maize price instability continue to occur in Mozambique in spite of policy reforms and great capacity for increased production in northern Mozambique. This study measured the efficiency of spatial maize price arbitrage in Mozambique's post-reform period. Spatial...
