CountiesWe analyze the impact of fiscal decentralization on U.S. county population, employment, and real income growth. Our findings suggest that government organization matters for local economic growth, but that the impacts vary by government unit and by economic indicator. We find that single-purpose governments per square mile have a positive impact on metropolitan population and employment growth, but no significant impact on nonmetropolitan counties. In contrast, the fragmentation of general-purpose governments per capita has a negative impact on employment and population growth in nonmetropolitan counties. Our results suggest that local government decentralization matters differently for metropolitan and nonmetropolitan counties.JEL Classification: E62, H7, R11

A dynamic labor market model is used to motivate the inclusion of population characteristics and industrial structure as determinants of regional employment instability. We examine how these factors influence regional employment instability using data from both metropolitan and nonmetropolitan regions in the United States. We find that population characteristics are important determinants of employment volatility and that increased industrial specialization (reduced diversification) increases employment volatility, but the magnitude of that influence drops substantially once population characteristics are considered. We also find that the influence of population characteristics and industrial specialization varies significantly across metropolitan and nonmetropolitan regions.

This article analyzes determinants of growth across labor markets in the United States, using a production function approach based on four inputs: labor, manufacturing investment, human capital investment, and public capital investment. We find little role for public capital investment in growth, but that manufacturing investment spurred growth in nonmetropolitan areas, in contrast to metropolitan areas. We also find that human capital investment mattered more for metropolitan areas than for nonmetropolitan areas. Further, the presence of more colleges and universities, more household amenities, and lower tax rates are all found to have encouraged human capital accumulation in U.S. labor markets.

The loss of the exchange rate as an independent policy instrument implied by European monetary union calls for an insurance scheme as a bu¡er against asymmetric shocks. We study the performance of such a system using historical data. A reasonable insurance scheme can be implemented on the basis of a fairly complex econometric formula. Simplifying the computation of the transfers severely worsens the performance of the system. Forcing the system to balance ¢nancially is not a critical constraint. The simulations show that stabilizing asymmetric shocks around a common trend may amplify the univariate variance of GDP for some member countries.* Manuscript received 30.3.95; ¢nal version received 4.12.96. 1 Atkeson and Bayoumi (1993) explore the extent to which capital markets provide households with insurance against asymmetric shocks in a monetary union. They ¢nd that this insurance is very limited empirically. 332The Manchester School
