This study involves an empirical analysis of the effect of social security wealth on wealth accumulation. My analysis takes as its point of departure a study by Feldstein and Pellechio on this subject. Their study used the same data source as analysed in this paper. Feldstein and Pellechio found strong support for the notion that increases in social security wealth caused families to reduce their wealth accumulation. My resuts indicate the strong conclusions reached by Feldstein and Pellechio are not robust. In particular, first, when I excluded a group, of farmers from our sample increases in social security wealth did not result in families reducing their wealth accumulation. Second, Feldstein and Pellechio calculated social security wealth using income measures from a single year. When I applied their methodlogy to income measures from a different year results were markedly affected.

We demonstrate how an auction model can be used in a traditional capital budgeting context to assign a value to the strategic advantage of long‐term forward contracts. Research in the field of industrial organization has pointed to the danger of ex post opportunistic bargaining as a motivation for the use of forward contracts in natural resources and manufactured products, but no operational procedure exists for estimating the value secured by these contracts. Arbitrage methods for valuing forward contracts assume a competitive market in which the factors creating the bargaining problem and motivating the use of long‐term contracts are not present. Use of the model is illustrated in the case of take‐or‐pay contracts for natural gas.

The relative importance of amenity and productivity differences in explaining wage differentials across metropolitan areas is estimated by utilizing the land and labor market clearing conditions for locational equilibrium of household and firms. Estimates of equilibrium wages and rents, along with estimates of households' budget shares and national income to land and labor rations, are used to identify amenity and productivity components of wages for each metropolitan area in the sample. While both components are found to be important, the productivity component, on average, accounts for a larger share of the intermetropolitan wage differentials.

A central question in development economics is, how can we account for differences in the levels of income and the rates of growth between the developed and less developed economies?

The ability of capital markets to distinguish firms of different value by the size of their initial equity offerings is attenuated when insiders can sell equity more than once. A model is developed in which there is price risk from holding equity between periods. When the uncertainty is small, there must be pooling in the first period. When uncertainty is large, the pooling equilibria dominate the separating equilibrium.
