This paper extends the Ramsey model's normative analysis to issues of generational welfare and intergenerational transfers. A planner, who maximizes the discounted welfare of an endless stream of generations, is intrinsically biased against larger cohorts, which are more costly to provide...

This paper reviews fundamental concepts in environmental economics and explores theoretical results regarding the choice of the key policy instruments for the control of externalities: taxes, subsidies and marketable permits. The paper explains why today market mechanisms are increasingly being...

A levy on the Clean Development Mechanism and other carbon trading schemes is a potential source of finance for climate change adaptation. An adaptation levy of 2% is currently imposed on all CDM transactions which could raise around $500 million between now and 2012. This paper analyses the...

This paper studies the estimation of a semi-strong GARCH(1,1) model when it does not have a stationary solution, where semi-strong means that we do not require the errors to be independent over time. We establish necessary and sufficient conditions for a semi-strong GARCH(1,1) process to have a...

Many important models utilize estimation of average derivatives of the conditional mean function. Asymptotic results in the literature on density weighted average derivative estimators (ADE) focus on convergence at parametric rates; this requires making stringent assumptions on smoothness of the...

We propose a model of equilibrium contracting between two agents who are “boundedly rational” in the sense that they face time costs of deliberating current and future transactions. We show that equilibrium contracts may be incomplete and assign control rights: they may leave some...

We present a survey of recent contributions in empirical organizational economics, focusing on management practices and decentralization. Productivity dispersion between firms and countries has motivated the improved measurement of firm organization across industries and countries. There appears...

This paper develops a new estimation procedure for characteristic-based factor models of security returns. We treat the factor model as a weighted additive nonparametric regression model, with the factor returns serving as time-varying weights, and a set of univariate non-parametric functions...

Although the operation of national coordinated wage-bargaining systems in EMU has produced low inflation rates, EMU-wide inflation has been above the ECB target rate for the last 3 years. By contrast, under the ERM, inflation rates declined steadily after 1992 to below 2 per cent in both the...

In a model with heterogeneity in managerial talent, we compare the economic and political consequences of reforms aimed at reducing fixed costs of entry (deregulation) and improving the efficiency of financial markets (financial reform). The effects of these reforms depend on the market where...
