The EU agenda for improving competitiveness is missing in action. Economic competitiveness has been a central plank in the development of the European Union - a relentless quest for policies that lead to more prosperity and that make European companies in world markets more successful. However,...

Realized volatility is a nonparametric ex-post estimate of the return variation. The most obvious realized volatility measure is the sum of finely-sampled squared return realizations over a fixed time interval. In a frictionless market, the estimate achieves consistency for the underlying...

We study how total factor productivity (TFP), energy prices, and the Great Moderation are linked. First we estimate a joint stochastic process for the energy price and TFP and establish that until the second quarter of 1982, energy prices negatively affected productivity. This spillover has...

This paper discusses a theoretical framework to study the issues of competition and incentives without relying on the standard profit-oriented “market” model in the context of the debates about public service reform in the UK. It uses the idea that the production of public services coheres...

According to the previous literature on hiring, ?rms face a trade-off when deciding on external recruiting: From an incentive perspective, external recruiting is harmful since admission of external candidates reduces internal workers’ career incentives. However, if external workers have high...

We study the effects of communication in an experimental tournament between teams. When teams, rather than individuals, compete for a prize there is a need for intra-team coordination in order to win the inter-team competition. Introducing communication in such situations may have ambiguous...

We present a model in which the media provide voters with information that is tainted by their own preferences, and derive an equilibrium in which media endorsements influence voting behavior. Competition for media endorsement causes political parties to adopt more centrist policies, which...

This paper introduces a method for solving numerical dynamic stochastic optimization problems that avoids rootfinding operations. The idea is applicable to many microeconomic and macroeconomic problems, including life cycle, buffer-stock, and stochastic growth problems. Software is provided.

In reviewing the theoretical and empirical literature on collusion, this paper distills methods for detecting cartels and distinguishing collusion from competition.
