This paper characterizes optimal consumption and investment policies for investors with asset return predictability, stochastic labor income and endogenously-determined retirement. We find that the ratio of total wealth-to-labor income (normalized wealth) is the primary determinant of the retirement decision and that at all ages, there exists a critical normalized wealth such that above this wealth, investors retire. We further consider the implications of endogenous retirement on portfolio choice. It is well known that human capital plays a large role in the determination of optimal equity proportion in financial portfolios. By endogenizing retirement, human capital becomes dependent on savings and investment decisions, which in turn depend on human capital. When compared to investors who exogenously retire at age 65, we find that low-wealth investors with the option to time retirement invest more aggressively while investors with slightly greater normalized wealth invest less aggressively prior to retirement. Investors with high normalized wealth behave almost the same as in the exogenous retirement case. This result contrasts the results in two recent papers and is due to the existence of stochastic labor income. Finally, we consider the impact of asset return/labor income correlation and find that equity holdings are nearly completely crowded-out by increased labor income (background) risk.

In this paper we study the consumption, labor supply, and portfolio decisions of an (infinitely-lived) individual who receives a certain wage rate and income from investment into a risky asset and a risk-free bond. Uncertainty about labor income arises endogenously, because labor supply evolves randomly over time in response to changes in financial wealth. We derive closed-form solutions for optimal consumption, labor supply and investment strategy. We find that deferring the retirement age stimulates optimal consumption over time and discourages optimal labor supply during the working life. We also find explicitly that optimal portfolio allocation becomes more 'conservative' when the individual approaches his prescribed retirement age. The effects of risk-aversion coefficients on optimal decisions are examined.

In this paper we consider a general consumption, portfolio and retirement optimization problem in which a working investor has borrowing constraints. Closed-form solutions are obtained for the utility maximization problems, and numerical procedures are given for the general utility function under borrowing constraints. Moreover we apply the results to the special utility function, the constant elative risk aversion (CRRA) utility function, and its numerical results suggest that the restriction to borrow future labor income makes the investor retire in a lower critical wealth level than in the case of no borrowing constraints.

I study optimal consumption and investment for retirement in an economic environment where an individual has retirement flexibility and borrowing constraints. I show that Friedman's (1957) permanent income hypothesis (PIH) is generalized with retirement and constrained borrowing against future labor income. In particular, a linear consumption rule in financial wealth and human wealth does not hold, and the non-linearity feature of option associated with retirement is of great importance to the consumption policy. Further, the first-order effect of inability to borrow money with human wealth on consumption and savings for retirement is captured by the generalized PIH rule. Finally, I find that an individual's aggressive risk taking by increasing stock investment turns out to be somewhat rational for retirement.

This book looks at the distribution of income and wealth and the effects that this has on the macroeconomy, and vice versa. Is a more equal distribution of income beneficial or harmful for macroeconomic growth, and how does the distribution of wealth evolve in a market economy? Taking stock of results and methods developed in the context of the 1990s revival of growth theory, the authors focus on capital accumulation and long-run growth. They show how rigorous, optimization-based technical tools can be applied, beyond the representative-agent framework of analysis, to account for realistic market imperfections and for political-economic interactions. The treatment is thorough, yet accessible to students and nonspecialist economists, and it offers specialist readers a wide-ranging and innovative treatment of an increasingly important research field. The book follows a single analytical thread through a series of different growth models, allowing readers to appreciate their structure and crucial assumptions. This is particularly useful at a time when the literature on income distribution and growth has developed quickly and in several different directions, becoming difficult to overview.

Optimal tax design attempts to resolve a well-known trade-off: namely, that high taxes are bad insofar as they discourage people from working, but good to the degree that, by redistributing wealth, they help insure people against productivity shocks. Until recently, however, economic research on this question either ignored people's uncertainty about their future productivities or imposed strong and unrealistic functional form restrictions on taxes. In response to these problems, the new dynamic public finance was developed to study the design of optimal taxes given only minimal restrictions on the set of possible tax instruments, and on the nature of shocks affecting people in the economy. In this book, Narayana Kocherlakota surveys and discusses this exciting new approach to public finance. An important book for advanced PhD courses in public finance and macroeconomics, The New Dynamic Public Finance provides a formal connection between the problem of dynamic optimal taxation and dynamic principal-agent contracting theory. This connection means that the properties of solutions to principal-agent problems can be used to determine the properties of optimal tax systems. The book shows that such optimal tax systems necessarily involve asset income taxes, which may depend in sophisticated ways on current and past labor incomes. It also addresses the implications of this new approach for qualitative properties of optimal monetary policy, optimal government debt policy, and optimal bequest taxes. In addition, the book describes computational methods for approximate calculation of optimal taxes, and discusses possible paths for future research.

In the past several decades, pension plans have become one of the most significant institutional influences on labor and financial markets in the U.S. In an effort to understand the economic effects of this growth, the National Bureau of Economic Research embarked on a major research project in 1980. Issues in Pension Economics, the third in a series of four projected volumes to result from thsi study, covers a broad range of pension issues and utilizes new and richer data sources than have been previously available. The papers in this volume cover such issues as the interaction of pension-funding decisions and corporate finances; the role of pensions in providing adequate and secure retirement income, including the integration of pension plans with social security and significant drops in the U.S. saving rate; and the incentive effects of pension plans on labor market behavior and the implications of plans on labor market behavior and the implications of plans for different demographic groups. Issues in Pension Economics offers important empirical studies and makes valuable theoretical contributions to current thinking in an area that will most likely continue to be a source of controversy and debate for some time to come. The volume should prove useful to academics and policymakers, as well as to members of the business and labor communities.

This volume represents the extension of Keynes' General Theory by a group of eminent economists. Each essay takes Keynes' work as a frame of reference for criticism, explorations and insights, whilst adding to the superstructure on the foundation of the General Theory. The essays also provide the necessary sense of perspective with a view to examining the Keynesian contribution to economic thought and also the limitations of Keynesian economics. The international contributors include: Dudley Dillard, Martin Bronfenbrenner, Mabel F. Timlin, William S. Vickrey, Don Patinkin, Howard R. Bowen, Gerald M. Meier, R.C.O. Matthews, Shinichi Ichimura, Anatol Murad, Lawrence R. Klein, Shigeto Tsuru, Paul P. Streeten, Lorie Tarshis and Franco Modigliani.

This book provides valuable information and analysis to managers, policymakers, and investment counselors in the rapidly expanding field of pension funding. American workers, too, need answers and insights on how to invest their money and plan for their retirement. fifteen of America's leading financial analysts address such pressing questions as -What is the current financial status of the elderly, and how vulnerable are they to inflation? -What is the impact of inflation on the private pension system, and what are the effects of alternative indexing schemes? -What roles can the social security system play in the provision of retirement income? -What is the effect of the tax code and the Employee Retirement Income Security Act of 1974 (ERISA) on corporate pension policy? -How well funded are corporate pension plans, and is a firm's unfunded pension liability fully reflected in the market value of its common stock? Many of the conclusions these experts reach contradict and challenge popular views, thus providing fertile ground for innovation in pension planning.
