This paper analyses the impact of labor market conditions on a firm's incentive to train its workers. In an equilibrium model of the labor market in which firms use both untrained and in-house trained workers, we show that the incidence of training increases with the tightness of the labor...

This paper was presented as the 2006 W.A. Mackintosh Lecture at Queen's University. I consider some of the leading arguments for assigning an important role to tracking the growth of monetary aggregates when making decisions about monetary policy. First, I consider whether ignoring money means...

If consumers wholly or partially control a firm with market power they will charge less than the profit maximising price. Starting at the usual monopoly price, a small price reduction will have a second order effect on profits but a first order effect on consumer surplus. Despite this desirable...

This paper asks whether the results obtained from using the standard approach to testing the influential Grossman and Helpman "protection for sale" (PFS) model of political economy might arise from a simpler setting. A model of imports and quotas with protection occuring in response to import...

We propose a new methodology for structural estimation of dynamic discrete choice models. We combine the Dynamic Programming (DP) solution algorithm with the Bayesian Markov Chain Monte Carlo algorithm into a single algorithm that solves the DP problem and estimates the parameters...

We use mechanism design to study efficient intertemporal payment arrangements when the ability of agents to perform certain welfare-improving transactions is subject to random and unobservable shocks. Efficiency is achieved via a payment system that assigns balances to participants, adjusts them...

Individual leaders have been central to the transformation of organizations, political institutions and many instances of social and economic reform. In this paper we take a first step towards analyzing the role of leadership to ask: when and how does a leader engineer change? We show that while...
