The distributional impact of unification and the 1992–93 recession on West German households

The 1992–93 recession in the western states of Germany has been attributed, in substantial measure, to the macroeconomic consequences of policies to finance unification. Studies of the costs of unification have not attempted to measure the burden of the recession. We estimate a dynamic, panel model of household incomes using data from the German Socio-Economic Panel (GSOEP) and use it to forecast what these incomes would have been in 1992–94 without a recession. Using a ratio of actual to forecast incomes, we compare the relative burden of the recession across households. Our findings suggest that western households below the median income bore the brunt of the combined impact of unification and the recession of 1992–93.

Demographic change and income inequality in the United States, 1976-1989

"The U.S. economy experienced significant increases in the degree of income inequality over the past two decades.... In this paper we consider the effects of race, age, female headship, and college education on the distribution of family income by developing a multivariate methodology that allows us to gauge the influence of one factor while holding other determinants of family incomes constant. Over the period studied we find that race had only a minor effect on the overall size distribution of income. Age had a somewhat greater effect than race. In contrast, the impact of female heads and college education were quite substantial. The multivariate estimates reveal that the effects of female heads and college education both increase the Gini to a much greater extent than the progressivity of federal income taxes decreases it. The effects of college education and female headed families on inequality have grown larger across time, while the influence of age has declined. We find that the effects of race on inequality have changed little over the 1976 to 1989 period."     

Collusion,entry, and market shares

This paper analyzes market entry and collusion in a model of duopoly with product-specific-set-up costs. The analysis demonstrates that collusion can alter the incentives for entry deterrence. We find conditions under which an established firm will permit entry and collude with a potential entrant even though entry deterrence is a viable option under noncooperative oligopoly rules. Conditions are also specified in which entry will be effectively impeded and collusion will not be undertaken.     

Regional Income Inequality and Welfare in China: A Dominance Analysis

Inference-based dominance analysis is applied to micro data containing comprehensive measures of rural and urban incomes in seven major regions of China. Ordinal inequality rankings are estimated for Lorenz curves of household income, per capita household income and square root equivalences scale adjusted income. Regional inequality is shown to be sensitive to the treatment of household size. The lack of reliable regional cost of living measures leads us to propose that entire food expenditure share quantile distributions be used as indicators of differences in well-being within and across regions. The results indicate that statistical rankings of Lorenz dominance and food share dominance are very different indicators of regional disparities in income and welfare in China. One urban region is shown to have been in the unenviable position in 1988 of being at the bottom of the Lorenz dominance ranking and tied for last in terms of food share dominance.

Allocative inefficiency and measures of market power

Conclusion This paper has shown that under conditions of both linear and constant price elasticity demand functions, market power as measured by the Lerner index and profit rates may easily move in the opposite direction of the welfare losses from monopoly. This means that changes in monopoly power, as measured by either Lerner indexes or profit rates, are not adequate to predict qualitative changes in allocative inefficiency.More (less) market power does not necessarily imply more (less) allocative inefficiency whether one is comparing different industries at a point in time or a given industry at different points in time. For these reasons, interpretation of the relation between market power as measured by the Lerner index or profit rates and market performance must proceed with caution.     

R&D spillovers and the case for industrial policy in an open economy

In this paper we consider the case for subsidies towards firmswhich generate R&D spillovers in open economies. We showthat in the presence of strategic behaviour by firms many expectedresults are overturned. Local R&D spillovers to other domesticfirms may justify an R&D tax rather than a subsidy; R&Dcooperation by local firms over-internalises the externalityand also justifies an R&D tax; and international spilloverswhich benefit foreign firms may justify a subsidy, even thoughthe government cares only about the profits of home firms.     

WATER BANKING AND RESTORATION OF ENDANGERED SPECIES HABITAT: AN APPLICATION TO THE SNAKE RIVER

Most river basins have experienced development of water projects to promote flood control, recreation, and hydropower and agricultural production. Though the projects helped establish stable economies, there have been adverse impacts to the natural environment and wildlife that reside in these river basins. One of the key policy tools for habitat restoration is management of instream flows. Alternative water banking policies for restoring habitat are compared using a spatial optimization model to identify which policies work best to augment instream flows for habitat restoration. Results indicate that policy goals dictate what type of water bank is preferred.     

POVERTY, NON-WHITE POVERTY, AND THE SEN INDEX

This paper investigates the impact of economic growth, and more specifically robust economic growth along with other macroeconomic determinants, on poverty levels using both the U.S. official measure of poverty and an estimated time series of Sen indices of poverty. The results reveal that the period of robust economic expansion that the U.S. economy experienced during the 1990s did not have a significant impact on poverty using either measure. In addition, we find that the impact of growth and other macro controls is dramatically different when a subset of the poverty population, namely non-white poverty, is investigated. The percentage of households headed by women is shown to be a significant factor in examining poverty for this subgroup.
