This paper proposes a nonparametric procedure to estimate market power for first-price auction data and applies the procedure to cattle procurement markets. Most previous studies have used parametric methods, which require specific functional forms for retail demand, input supply and processors'...

Many recent studies have evaluated potential market power in the U.S. cattle procurement market using either new empirical industrial organization (NEIO) models or auction models. The model derived here shows the NEIO model holds in some cases, while the auction theory can fully describe market...

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...

Agronomic research on crop response to nitrogen fertilizer suggests that a plateau function may be appropriate, but the plateau varies across fields and years. Available models that treat the plateau as a stochastic variable are not readily extendable to handle field or year random effects as...

The impacts of market reforms on prices volatility in developing countries are not well understood because analysts have not been able to predict the impacts. This study investigates whether the reforms have exacerbated the degree of spatial volatility of maize price in Tanzania using ARCH-M...
