A structural life-cycle retirement model with an improved specification over previous models is used to analyze and compare the long-run effects on the labor supply of older workers of the 1983 Social Security reforms. The effects of separate provisions from the 1983 amendments are examined. These include the raising of the normal retirement age to 67, the increase in the delayed retirement credit to 8%, and the lowering of the reduction rate for earnings over the test amount to $1.00 for every $3.00 of earnings.

Even when only labor is scarce, the validity of a labor theory of value depends on reducing all labor to a homogeneous equivalent. The various implicit or explicit efforts of Smith, Ricardo, and Marx to do so are shown to fail on more counts than previously recognized. The labor theory is also shown to fail when laborers are not indifferent among alternative occupations.

Results based on pooled time series and cross section data are presented, which indicate that state and local tax increases significantly retard economic growth when the revenue is used to fund transfer payments. However, when the revenue is used instead to finance improved public services (such as education, highways, and public health and safety) the favorable impact on location and production decisions provided by the enhanced services may more than counterbalance the disincentive effects of the associated taxes. These findings underscore the importance of considering the incentives provided by a state's expenditures as well as by its taxes. I N the past several years a number of states have implemented limitations on taxes or expenditures, while others have raised tax rates in response to the revenue shortfalls of the early 1980s. Although much of the ongoing debate over state fiscal structures revolves around expressed preferences over tax-expenditure combinations per se, the question of how state and local taxes may affect economic growth is often central to the discussion. Nonetheless, the empirical evidence remains sparse. Previous studies can be divided into two broad categories: assessments of the magnitudes of tax costs, and statistical analyses of the relationship between tax rates and growth. Cost studies have tended to minimize the role of taxes in business location decisions, either because state and local taxes are a relatively small component of total costs for most businesses, or because interstate tax differences are small relative to other cost differences between states.' Although these results suggest that the role played by taxes is a minor one, describing how large the tax disparities may be is not the same as ascertaining their economic effect. Of the statistical studies many, including Bloom (1955), Thompson and Mattila (1959), and Carlton (1979,1983), find no relationship between taxes and growth. However, Kleine (1977), Grieson (1980) and, generally, Grieson et al. (1977) report negative correlations. Romans and Subrahmanyam (1979) find growth to be negatively related to the fraction of revenues devoted to transfer payments and a variable which they claim measures personal tax progressivity, but positively related to business taxes. With the exception of Carlton (who estimates models of the birth and size of firms within metropolitan areas) and the Grieson et al. (1977) and Grieson (1980) studies (which consider taxes in New York City and Philadelphia), these authors use data from a single cross section of states. More recently, Newman (1983) and Plaut and Pluta (1983) both use cross sectional data from two time periods, the former finding negative effects of corporate tax rates and the latter yielding mixed results. In this study we utilize a time series (from 1965 through 1979) of cross sections of 48 states. Exploiting the richness of this data set, we are able to allow for otherwise unexplained differences between states which could be expected to bias results based on a single cross section. Moreover, this much larger sample provides the statistical power necessary to disentangle the separate effects of different categories of taxes, public expenditures, and transfer payments; a distinguishing feature of this paper is that we explicitly recognize the government budget constraint linking these fiscal variables and the deficit or surplus. In addition, we have taken account of the effects of labor force characteristics by including variables for wage rates, unionization, and population density. Our results indicate that tax increases significantly retard economic growth when the revenue is used to fund transfer payments; as a result, programs of income redistribution are more effectively undertaken at the federal than at the state and local level.

This paper examines real wage measures that include leisure and nonlabor income in consumption decisions with respect to the advantages and disadvantages of partial versus complete welfare orderings and of utility-based versus utility-free wage indices. In addition, we argue that the usefulness of a real wage measure beyond welfare comparison has been ignored. To test the robustness of utility-based indices, these real wage measures are calculated for two different utility-function specifications, the indirect addilog system and the linear expenditure system. Further comparisons are made against index bounds that are independent of the functional form for preferences.
