This article considers bilateral imperfect competition between processors and retailers to estimate the trade off between market power and cost efficiency. The model is based on pricing rules from a firm's profit maximization and nests both oligopoly and oligopsony models. An empirical analysis...

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'...

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...
