This paper proposes a general way to conceive public policy when there is no consensual account of the situation of interest. The approach builds on an extension and dual formulation of the traditional theory of economic policy. It does not need a representative policymaker’s utility function...

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...

This paper examines the key design mechanisms of existing and proposed cap-and-trade markets. First, it is shown that the hybrid systems under investigation (price floor using a minimum price guarantee, price collar, allowance reserve, options offered by the regulator, and offset relaxation) can...

We exploit a unique panel of 75 metro areas (‘cities’) across the globe and employ a cityfixed effects model to identify the determinants of within-city changes in air pollution concentration between 2005 and 2011. Increasing car and population densities significantly reduce air pollution...

We present a modified open monocentric city model that assumes that land is available for conversion into new housing throughout the city. The model predicts that positive local income shocks (i) increase the city’s share of multi-family housing in new construction and (ii) lead to the...

A simple model of offshoring is used to integrate the complex gallery of results that exist in the theoretical offshoring/fragmentation literature. The paper depicts offshoring as ‘shadow migration’ and shows that this allows straightforward derivation of the general equilibrium effects on...

The Long-Term Consequences of Regional Specialization* What are the consequences of resource-based regional specialization, when it persists over a long period of time? While much of the literature argues that specialization is beneficial, recent work suggests it may be costly in the long run,...
