This Essay describes an approach for designing antitrust rules for assessing whether firms have engaged in anticompetitive unilateral practices that is based in part on the error-cost framework pioneered by Judge Easterbrook. We focus particularly on the role of economic theory and evidence in...

Two-step instrumental variable estimators for dynamic panel data models are considered that are asymptotically efficient under some auxiliary assumptions, but remain consistent when the assumptions are violated. Asymptotic efficiency is defined in relation to the information bound for the...

The purpose of this paper is to review recently development methods of estimation of nonlinear fixed effects panel data models with reduced bias properties. We begin by describing fixed effects estimators and the incidental parameters problem. Next the explain how to construct analytical bias...

The age at which children leave the parental home differs considerably across countries. We present a theoretical model predicting that higher job security of parents and lower job security of children may delay emancipation. We then provide aggregate evidence wich supports this hypothesis for...

The Spanish electricity spot market is highly concentrated both on the seller and the buyer side. Furthermore, unlike electricity spot markets in other deregulated electricity systems, large buyers and sellers are typically vertically integrated. This allows both large net sellers and large net...

The protection that innovators obtain through intellectual property rights crucially depends on their incentives and ability to litigate infringers. Taking patents as a notable example, we study how the financing of legal costs can alter the incentives to litigate in defense of a petent and,...

We apply stochastic stability to study the evolution of bidding behaviour in private-value second-price, first-price and k-double auctions. The learning process has a strong component of inertia but with a small probability, the bids are modified in the direction of ex-post regrets. We identify...

We derive the statistical properties of the SNP densities of Gallant and Nychka (1987). We show that these densities, which are always positive, are more general than the truncated Gram-Charlier expansions of Jondeau and Rochinger (2001), who impose parameter restrictions to ensure positivity....

This article describes the basic elements of the cooperative approach to game theory, one of the two counterparts of the discipline. After the presentation of some basic definitions, the focus will be on the core and the Shapley value, two of the most central solution concepts in cooperative...

In this paper we estimate the causal effect of providing “intensive” informal care to elderly parents on labour market participation decisions for European women who are themselves approaching retirement. In particular, we consider the frequency or intensity of this help and we focus on...
