Risk Management, Capital Budgeting and Capital Structure Policy for Financial Institutions: An Integrated Approach

Abstract: We develop a framework for analyzing the capital allocation and capital structure decisions facing financial institutions such as banks. Our model incorporates two key features: i) value-maximizing banks have a well-founded concern with risk management; and ii) not all the risks they face can be frictionlessly hedged in the capital market. This approach allows us to show how bank-level risk management considerations should factor into the pricing of those risks that cannot be easily hedged. We examine several applications, including the evaluation of proprietary trading operations, and the pricing of unhedgeable derivatives positions.

The Consumption Smoothing Benefits of Unemployment Insurance

Abstract: Previous research on unemployment insurance (UI) has focused on the costs of the program, in terms of the distorting effects of generous UI benefits on worker and firm behavior. For assessing the optimal size of an unemployment insurance program, however, it is also important to gauge the benefits of increased UI generosity, in terms of smoothing consumption across periods of joblessness. I do so through a reduced form approach which directly measures the effect of legislated variations in UI benefits on consumption changes among individuals becoming unemployed. I use annual observations on food consumption expenditures for 1968-1987 from the Panel Study of Income Dynamics, matched to information on the UI benefits for which unemployed persons were eligible in each state and year. I estimate that a 10 percentage point increase in the UI replacement rate leads to a consumption fall upon unemployment which is 2.7% smaller. Over this period, the average fall in consumption for the unemployed was 7%; my results imply that, in the absence of unemployment insurance, this fall would have been over three times as large. I also find that the positive effect of UI only extends for one period, smoothing consumption during initial job loss but having no permanent effect on consumption levels; that individuals who anticipate layoff see a smaller consumption smoothing effect; and that UI appears to somewhat crowd out other forms of public consumption insurance. Despite the substantial estimated consumption smoothing effect, however, my results imply that the optimal UI benefit level is within the range of current replacement rates only at fairly high levels of risk aversion.

Innovations and Technological Spillovers

Abstract: In this paper we analyze the evidence from a large number of studies on three specific questions pertaining to RD the social rates of return of RD the channels of transmissions have been exports, foreign direct investment, and multinational enterprises' research operations, the latter being the most dynamic agents of technology transfer. With the further globalization of business activities, international technology transfers will be a major source of new R&D spillovers.

Expected Option Returns

Abstract: This paper examines expected option returns in the context of mainstream asset pricing theory. Under mild assumptions, call options have expected returns which exceed those of their underlying security and which are increasing in their strike prices. Likewise, put options have expected returns which are below the risk-free rate and which are also increasing in their strike prices. Across a variety of time periods and return frequencies, S&P 500 and 100 index option returns strongly exhibit these characteristics. Under stronger assumptions, expected option returns are a linear function of option betas. Fama-MacBeth-style option return regressions produce risk premia close to the expected market return. However, the regression intercepts are significantly below zero. As a result, zero-beta, at-the-money straddle positions produce average losses of approximately three percent per week. Zero-beta straddles in other markets also lose money consistently. These findings suggest that some additional factor, such as systematic stochastic volatility, is priced in option returns.
