In an OLG (overlapping generations) economy with only two risky factors of production, human capital and physical capital, a social security system that optimally shares risks among generations was incorporated. By allowing for physical capital acumulation, this paper extends John Compbell's fixed supplies of asset economy into a dynamic environment. Under certain conditions, this new system has milder effects than Campbell's on risk-free interest rate, and prices and risk premium of physical capital. We also find that the level of human capital could make the system's effects on asset markets ambiguous and steady state physical capital stock is lower in the long run equilibrium.

In the presence of overlapping generations, markets are incomplete because it is impossible to engage in risksharing trades with the unborn. In such an environment the government can use a social security system, with contingent taxes and benefits, to improve risksharing across generations. An interesting question is how the form of the social security system affects asset prices in equilibrium. In this paper we set up a simple model with two risky factors of production: human capital, owned by the young, and physical capital, owned by all older generations. We show that a social security system that optimally shares risks across generations exposes future generations to a share of the risk in physical capital returns. Such a system reduces precautionary saving and increases the risk-bearing capacity of the economy. Under plausible conditions it increases the riskless interest rate, lowers the price of physical capital, and reduces the risk premium on physical capital.

An introduction to the theory and methods of empirical asset pricing, integrating classical foundations with recent developments. This book offers a comprehensive advanced introduction to asset pricing, the study of models for the prices and returns of various securities. The focus is empirical, emphasizing how the models relate to the data. The book offers a uniquely integrated treatment, combining classical foundations with more recent developments in the literature and relating some of the material to applications in investment management. It covers the theory of empirical asset pricing, the main empirical methods, and a range of applied topics. The book introduces the theory of empirical asset pricing through three main paradigms: mean variance analysis, stochastic discount factors, and beta pricing models. It describes empirical methods, beginning with the generalized method of moments (GMM) and viewing other methods as special cases of GMM; offers a comprehensive review of fund performance evaluation; and presents selected applied topics, including a substantial chapter on predictability in asset markets that covers predicting the level of returns, volatility and higher moments, and predicting cross-sectional differences in returns. Other chapters cover production-based asset pricing, long-run risk models, the Campbell-Shiller approximation, the debate on covariance versus characteristics, and the relation of volatility to the cross-section of stock returns. An extensive reference section captures the current state of the field. The book is intended for use by graduate students in finance and economics; it can also serve as a reference for professionals.

Edited by Rajnish Mehra, this volume focuses on the equity risk premium puzzle, a term coined by Mehra and Prescott in 1985 which encompasses a number of empirical regularities in the prices of capital assets that are at odds with the predictions of standard economic theory.

We provide a systematic analysis of the properties of individual returns to wealth using twelve years of population data from Norway’s administrative tax records. We document a number of novel results. First, during our sample period individuals earn markedly different average returns on their financial assets (a standard deviation of 14%) and on their net worth (a standard deviation of 8%). Second, heterogeneity in returns does not arise merely from differences in the allocation of wealth between safe and risky assets: returns are heterogeneous even within asset classes. Third, returns are positively correlated with wealth: moving from the 10th to the 90th percentile of the financial wealth distribution increases the return by 3 percentage points - and by 17 percentage points when the same exercise is performed for the return to net worth. Fourth, wealth returns exhibit substantial persistence over time. We argue that while this persistence partly reflects stable differences in risk exposure and assets scale, it also reflects persistent heterogeneity in sophistication and financial information, as well as entrepreneurial talent. Finally, wealth returns are (mildly) correlated across generations. We discuss the implications of these findings for several strands of the wealth inequality debate.

Two leading economists develop a theory explaining the demand for and supply of liquid assets. Why do financial institutions, industrial companies, and households hold low-yielding money balances, Treasury bills, and other liquid assets? When and to what extent can the state and international financial markets make up for a shortage of liquid assets, allowing agents to save and share risk more effectively? These questions are at the center of all financial crises, including the current global one. In Inside and Outside Liquidity, leading economists Bengt Holmström and Jean Tirole offer an original, unified perspective on these questions. In a slight, but important, departure from the standard theory of finance, they show how imperfect pledgeability of corporate income leads to a demand for as well as a shortage of liquidity with interesting implications for the pricing of assets, investment decisions, and liquidity management. The government has an active role to play in improving risk-sharing between consumers with limited commitment power and firms dealing with the high costs of potential liquidity shortages. In this perspective, private risk-sharing is always imperfect and may lead to financial crises that can be alleviated through government interventions.

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.
