Creator: Jagannathan, Ravi and Wang, Zhenyu Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 517 Abstract:
In empirical studies of the CAPM, it is commonly assumed that (a) the return to the value weighted portfolio of all stocks is a reasonable proxy for the return on the market portfolio of all assets in the economy, and (b) betas of assets remain constant over time. Under these assumptions, Fama and French (1992) find that the relation between average return and beta is flat. We argue that these two auxiliary assumptions are not reasonable. We demonstrate that when these assumptions are relaxed, the empirical support for the CAPM is surprisingly strong. When human capital is also included in measuring wealth, the CAPM is able to explain 28 percent of the cross sectional variation in average returns in the 100 portfolios studied by Fama and French. When, in addition, betas are allowed to vary over the business cycle, the CAPM is able to explain 57 percent. More important, relative size does not explain what is left unexplained after taking sampling errors into account.

Creator: Braun, R. Anton Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 506 Abstract:
This paper investigates the macroeconomic effects of cyclical fluctuations in marginal tax rates. It finds that systematically including tax variables in a standard real business cycle model substantially improves the model's ability to reproduce basic facts about postwar U.S. business cycle fluctuations. In particular, modeling fluctuations in personal and corporate income tax rates increases the model's predicted relative variability of hours and decreases its predicted correlation between hours and average productivity. Fluctuations in tax rates produce large substitution effects that alter the leisure/labor supply decision.

Creator: Green, Edward J. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 501 Abstract:
I consider two theories of the determination of political institutions. One of these theories stresses effects of changes in the balance of military power between the ruler and subjects on the distribution of property rights which the political system enforces. The other theory emphasizes the effect of changing informational constraints which require institutional changes to be made in order to maintain efficiency. I examine how each of these theories would apply to explaining the development of parliamentary government in thirteenth-century England. My general conclusion is that both theories are required to understand fully the process by which liberal political institutions emerge.

Creator: Aiyagari, S. Rao and Peled, Dan Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 503 Abstract:
It is often argued that with a positively skewed income distribution (median less than mean) a majority voting over proportional tax rates would result in higher tax rates than those that maximize average welfare, and will accordingly reduce aggregate savings. We reexamine this view in a capital accumulation model, in which distorting redistributive taxes provide insurance against idiosyncratic shocks, and income distributions evolve endogenously. We find small differences of either sign between the tax rates set by a majority voting and a utilitarian government, for reasonable parametric specifications. We show how these differences reflect a greater responsiveness of a utilitarian government to the average need for the insurance provided by the tax-redistribution scheme. These conclusions remain true despite the fact that the model simulations produce positively skewed distributions of total income across agents.

Creator: Boyd, John H. and Smith, Bruce D. (Bruce David), 1954-2002 Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 522 Abstract:
We consider a two country growth model with international capital markets. These markets fund capital investment in both countries, and operate subject to a costly state verification (CSV) problem. Investors in each country require some external finance, but also provide internal finance, which mitigates the CSV problem. When two identical (except for their initial capital stocks) economies are closed, they necessarily converge monotonically to the same steady state output level. Unrestricted international financial trade precludes otherwise identical economies from converging, and poor countries are necessarily net lenders to rich countries. Oscillation in real activity and international capital flows can occur.

Creator: Smith, Bruce D. (Bruce David), 1954-2002 Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 230 Abstract:
An overlapping generations model is developed that contains labor markets in which adverse selection problems arise. As a response to these problems, quantity rationing of labor occurs. In addition, the model is capable of generating (a) random employment and prices despite the absence of underlying uncertainty in equilibrium; (b) a statistical (nondegenerate) Phillips curve; (c) procyclical movements in productivity; (d) correlations between aggregate demand and unemployment (and output); (e) an absence of correlation between unemployment (employment) and real wages. In addition, the Phillips curve obtained typically has the "correct" slope. Finally, the model reconciles the theoretical importance and observed unimportance of intertemporal substitution effects, and explains why price level stability may be a poor policy objective.
