Charging for social marginal costs is efficient regardless of price elasticities, but the importance of getting prices"right"is greater the more manageable, or elastic, the demand. In efficient pollution control programs, options to make cars cleaner are combined optimally with demand...

The authors explore the relationship between economic growth and environmental quality by analyzing patterns of environmental transformation for countries at different income levels. They look at how eight indicators of environmental quality evolve in response to economic growth and policies...

Traditional specifications of money demand have commonly been plagued by persistent overprediction, implausible parameter estimates, andhighly autocorrelated errors. The authors argue that some of these problems stem from the failure to account for the impact of financial innovation. They...

Price and income elasticities estimated from a country's export demand function are used both to predict and to prescribe effective export strategies. But the focus on elasticities has led to the neglect of an important empirical regularity: a strong persistencein the growth rate of a country's...

The author provides theoretical and empirical evidence of a negative association between income inequality and real exchange rates. First, he builds a theoretical model showing the transmission mechanism from inequality to real exchange rates. Second, using cross-country data, he demonstrates...

The median voter hypothesis is important to endogenous growth theories because it provides the political mechanisms through which voters in more unequal countries re-distribute a greater proportion of income and thus (it is argued), by blunting incentives, reduce the country's growth rate. But...

The authors compare three approaches to linking representative-household macro models with micro household income data in terms of their implications for measuring the poverty and distributional effects of policy shocks. These approaches are a simple micro-accounting method, an extension of that...

Policy recommendations to reduce the growth of public spending are haunted by the inevitability of two factors. First Wagner's law, the hypothesis that with economic development an increasing share of GDP is devoted to public spending, and secondly, Baumol's effect, that as economies develop,...

The difficulties most Latin American countries have experienced in returning to sustained growth after the world recession and debt crisis of 1982 have surprised and frustrated many observers. Concern is increasingly expressed about the social costs of this period of recession and adjustment,...

A recent but rapidly growing empirical literature focuses on the relationship between public and private capital. But for the most part, it ignores the heterogeneity of public investment. In many countries, especially in the developing world, public investment includes not only basic...
