Risk aversion, wealth, and the DARA hypothesis: A new test

The Pratt-Arrow hypothesis of decreasing absolute risk aversion (DARA) is widely invoked in economic models of uncertainty but empirical tests, especially those using nonexperimental data, have yielded mixed results. This paper reexamines the DARA hypothesis using an expected utility model of life insurance demand and a 23-year sample of aggregate time series data from the U.S. After controlling for household size, age, income, loss probabilities, premium expenses, and inflation, the effect of wealth on insurance demand is found to be positive and statistically significant in linear and loglinear regressions, explaining more than 93 percent of the variation in coverage. Thus, in contrast to the prevailing theory, this empirical test presents evidence of increasing absolute risk aversion. This research was completed during a sabbatical at the University of Pennsylvania's Wharton School of Business. The financial support of the S. S. Huebner Foundation for Insurance Education is greatly appreciated.

MEASURING MULTIDIMENSIONAL POVERTY: AN EMPIRICAL COMPARISON OF VARIOUS APPROACHES

This paper makes a systematic comparison of four approaches to multidimensional poverty analysis based respectively on the theory of fuzzy sets, information theory, efficiency analysis and axiomatic derivations of poverty indices. The database was the 1995 Israeli Census that provided information on the ownership of various durable goods. There appears to be a fair degree of agreement between the various multidimensional poverty indices concerning the identification of the poor households. The four approaches have also shown that poverty decreases with the schooling level of the head of the household, first decreases and then increases with his/her age and with the size of the household. Poverty is higher when the head of the household is single and lower when he/she is married, lowest when the head of the household is Jewish and highest when he/she is Muslim. Poverty is also higher among households whose head immigrated in recent years, does not work or lives in Jerusalem. These observations were made on the basis of logit regressions. This impact on poverty of many of the variables is not very different from the one that is observed when poverty measurement is based only on the income or the total expenditures of the households.     

Audit personnel salaries and audit quality

This study examines the relation between audit personnel salaries and office-level audit quality. We measure audit personnel salaries at the associate, senior, and manager ranks for Big 4 audit offices from 2004 to 2013, using unique individual-auditor-level data obtained from the U.S. Department of Labor. We find that offices that pay lower salaries have a higher percentage of clients that experience restatements. In related analyses, we also find lower levels of audit quality when audit employees are paid less, relative to other lines of service in accounting firms. Finally, we document positive and significant associations between salary and fees, suggesting that audit offices pass some of the cost of higher labor onto their clients. Overall, our findings provide important initial evidence on the role of audit salary and its relation to audit quality and audit fees.     

Assessing impact of regulatory risk on shareholders’ wealth

Research indicates that regulatory risk increases required return on investment by investors and causes underinvestment in industries with high sunk costs. The effects of regulatory changes may be measured by estimating the abnormal returns associated with the event. The results may suggest to regulators what should be encouraged or avoided. This article utilizes a fixed effects regression to examine abnormal returns from changes in Philippine nationalization regulations. The results are consistent with extant literature. Supreme Court decisions, which increased uncertainty and regulatory risk, produced negative abnormal returns. The initial release of draft implementing rules did not produce statistically significant effects, but a succeeding draft favouring liberalization, produced positive abnormal returns.     

The Capital Structure of PE‐Funded Companies (and How New Debt Instruments and Investors Are Expanding Their Debt Capacity)

The capital structures and financial policies of companies controlled by private equity firms are notably different from those of public companies. The concentration of ownership and intense monitoring of leveraged buyouts by their largest investors (that is, the partners of the PE firms who sit on their boards), along with the contractual requirement of PE funds to return their capital within seven to ten years, have resulted in capital structures that are far more leveraged than those of their publicly traded counterparts, but also considerably more provisional and “opportunistic.” Whereas the average U.S. public company has long operated with roughly 30% debt and 70% equity, today's typical private‐equity sponsored company is initially capitalized with an “upside‐down” structure of 70% debt and just 30% equity, and then often charged with working down its debt as quickly as possible. Although banks supplied most of the debt for the first wave of LBOs in the 1980s, the remarkable growth of the private equity industry in the past 25 years has been supported by the parallel development of a new leveraged acquisition finance market. This financing innovation has led to a general movement away from a bankcentered funding base to one comprising a relatively new set of institutional investors, including business development corporations and hedge funds. Such investors have shown a strong appetite for new debt instruments and risks that banks have been unwilling or, thanks to increased capital requirements and other regulatory burdens, prohibited from taking on. Notable among these new instruments are second‐lien loans and uni‐tranche debt—instruments that, by shifting the allocation of claims on the debtor's cash flow and assets in ways consistent with the preferences of these new investors, have had the effect of increasing the debt capacity of their portfolio companies. And such increases in debt capacity have in turn enabled private equity funds—now sitting on near‐record amounts of capital from their limited partners—to bid higher prices and compete more effectively in today's intensely competitive M&A market, in which high target acquisition purchase prices are being fueled by a strong stock market and increased competition from corporate acquirers.     

Downside Risk

Economists have long recognized that investors care differentlyabout downside losses versus upside gains. Agents who placegreater weight on downside risk demand additional compensationfor holding stocks with high sensitivities to downside marketmovements. We show that the cross section of stock returns reflectsa downside risk premium of approximately 6% per annum. Stocksthat covary strongly with the market during market declineshave high average returns. The reward for beasring downsiderisk is not simply compensation for regular market beta, noris it explained by coskewness or liquidity risk, or by size,value, and momentum characteristics.

Rising marginal cost and concavity of the production function

Suppose a production function, f, is continuous, quasi-concave and weakly monotone on the non-negative orthant of Euclidean n-space. Let c(·, ·) be the associated cost function. Then it is shown that f is concave if and only if for each w, c(w, ·) is convex.     

Macroeconomic Policy Interaction under EMU: A Dynamic Game Approach

In this article, we study macroeconomic stabilization in the Economic and Monetary Union (EMU) using a dynamic game approach. With the aid of a stylized macroeconomic model, this article analyzes the transmission and interaction of national fiscal policies and monetary policy of the European Central Bank (ECB) in the EMU. A special focus is on the effects of labor market institutions in the participating countries and of the introduction of fiscal stringency criteria like those imposed in the Stability and Growth Pact.
