This paper proposes a methodology for analyzing nonlinear pricing data with an illustration on cellular phone. The model incorporates consumer exclusion. Assuming a known tariff, we establish identification of the model primitives using the first-order conditions of both the firm and the...

We examine the extent to which vertical and horizontal market structure can together explain incomplete pass-through. We develop a model that highlights the interactions between horizontal and vertical structure and their effects on pass-through from commodity to wholesale prices and wholesale...

Coinage debasement in medieval and early modern Europe remains an ill-understood topic; and indeed an often cited article ("The Debasement Puzzle": Velde and Weber, 1996) sought to demonstrate that coinage debasements were both impractical and economically futile. The purpose of this study is to...

We assess the effects of a major land-policy change on farm size and agricultural productivity using a quantitative model and micro-level data. We study the 1988 land reform in the Philippines that imposed a ceiling on land holdings and severely restricted the transferability of the...

In this paper, we discuss the key conditions for the identification and estimation of the local average treatment effect (LATE, Imbens and Angrist, 1994): the valid instrument assumption (LI) and the monotonicity assumption (LM). We show that the joint assumptions of LI and LM have a testable...
