Effective agricultural policymaking requires the accurate estimation of the production technology and efficiency of farms. However, several methodological issues should be considered when modelling production and estimating technical efficiency. In this paper, we focus on two of...

We study the monotonicity of sender's equilibrium strategy with respect to her type in signalling games. We use counterexamples to show that when the sender's payoff is non-separable, the Spence-Mirrlees condition cannot rule out equilibria in which the sender uses non-monotone strategies. These...

We present necessary and sufficient revealed preference conditions to verify whether a finite data seton nonlinear budget sets is consistent with the maximization of a quasi–concave utility function. Ourresults can be used to test for convexity of the underlying preference relation. We also...
