This paper examines the relationships among capital regulation, deposit insurance, and the optimal bank interest margin. In a model where loan losses are the source of uncertainty, changes in capital regulation or deposit insurance premiums have direct effects on the bank's interest margin. An increase in bank capital requirement or in deposit insurance premiums results in a reduced interest margin under nonincreasing risk aversion. Comparative static analysis also explores the relation between asset quality and interest margin. It is shown that a mean-preserving spread of the distribution of loan losses results in a reduced margin.

This paper provides closed form solutions for futures and European futures options on pure discount bonds under the Ornstein-Uhlenbeck (normal) process. A significant difference between Black's model (1976) and the model in this paper for futures options is discussed.

Previous research has separately addressed the problem of estimating risk in the presence of infrequent trading and the problem of estimating quality-adjusted returns in markets with quality variation in the observed price series. This paper simultaneously addresses both problems by applying a signal extraction method for unequally spaced data to decompose the observed price series with varying times between transactions into a quality-adjusted, permanent component (which would be observable in the absence of quality variation) plus a stationary, transitory quality variation component. Stamp auction transaction prices provide an application. Auction quality grading is treated in a manner analogous to bond ratings. Almost all of the observed variance is attributed to the auction quality variation. The observed auction returns and stock index returns are not well related.

This paper reexamines long-horizon stock returns and finds that previous work overstates the evidence of mean reversion. The overstatement is largely due to the implicit weighting of ordinary least-squares tests, which place more weight on the Depression and World War II observations, which have both large error variances and stronger mean-reverting tendencies. Additionally, the reliance on asymptotic statistics and the improper focus on only the most negative estimates of mean reversion contribute to the overstatement. Using generalized least-squares randomization tests on the 1926 to 1987 period, the random walk cannot be rejected for value- or equally-weighted real returns at any of 10 return horizons or by joint tests over all 10 horizons simultaneously. Additionally, the random walk cannot be rejected for the extended 1871 to 1987 period.

This paper develops a specialized principal-agent model of the investor-investment advisor relationship and embeds the standard advisory compensation schedule in the model. Advisors are endowed with information-gathering abilities and investors are endowed with funds. Information-gathering services are traded indirectly through the investor's receipt of portfolio returns net of advisory fees. Model results show that the parameters of the compensation schedule are both a function of the idiosyncracies of an advisor's information services and the degree of risk sharing between the advisor and investor. Several predictions of the model are supported using data on mutual fund advisors. Unsupported predictions may be due to self-selection of advisors by risk tolerance.

Even if true abnormal returns are uncorrelated, estimated abnormal returns are not. This paper presents a simple formula for the variance of estimated cumulative abnormal returns. Both returns and dummy variable procedures for estimating the standard error correctly, taking account of both intertemporal and contemporaneous correlation of estimated residuals, are discussed. They are then applied to an event study of post-merger performance. It is shown that ignoring either the intertemporal or contemporaneous correlation of residuals can result in significant underestimates of standard errors.

This paper provides a theoretical and empirical investigation of the role of the secondary market in the pricing of initial public offerings. We argue that incomplete spanning of the primary issues in the secondary market and limited investor access play an important role in the pricing of initial public offerings. Utilizing a segmented market approach wherein IPO offering values are determined in the primary market and after-market bid prices are determined in the centrally accessed secondary market, we derive a price differential in the primary and secondary markets that is consistent with the received notion of IPO underpricing. Empirical tests on a large sample of IPOs provide results that are consistent with the predictions of our theoretical analysis.

This paper identifies five universal currency hedge ratio (UHR) definitions. These are hedge positions in foreign bonds, stated as a fraction of national or global equity portfolios, that are the same for all investors, regardless of nationality. The first three involve the total demand for foreign bonds and depend on equities not being held for hedging purposes. The last two are associated with variance-minimizing regression hedges. These hold, in general, but are designed exclusively for hedging other traded asset positions. Jensen's inequality makes the choice of measurement currency irrelevant and makes the HRs universal without affecting their values.

This study examines the average abnormal returns, average abnormal trading volume, and reported insider trading of corporate control target firms during a period of possibly informed trading. This period begins on the unpublicized initiation date (as reported in a postannouncement date proxy statement or 14-D1) and ends on the publication date of the first Wall Street Journal story signalling an impending change in corporate control. We find that the preannouncement date average abnormal return noted by other researchers begins after the unpublicized initiation date of the transaction. We find no evidence of the preannouncement date average abnormal trading volume noted by previous researchers; instead, we find average abnormal volume beginning with the first public information regarding the transaction.

The author sets out a realist defense of the claim that in the absence of an international enforcement agency, multinational corporations operating in a competitive international environment cannot be said to have a moral obligation to contribute to the international common good, provided that interactions are nonrepetitive and provided effective signals of agent reliability are not possible. Examples of international common goods that meet these conditions are support of the global ozone layer and avoidance of the global greenhouse effect. Pointing out that the conclusion that multinationals have no moral obligations in these areas is deplorable, the author urges the establishment of an international enforcement agency.

This paper deals with the genesis, development, and impact of Military Keynesianism in the U.S. Its impact on the civilian sector is examined in terms of: geographical distribution of military spending, sectoral militarization, labor market and occupational distortion, the militarization of R & D, R & D's impact on American competitiveness in the international market, the parasitic role of the military contract system and the unethical and exploitative role of military contractors.

This paper examines the issues related to disarmament and economic conversion with special reference to bills pending before the Congress. The author suggests a redefinition of “national security” in tune with the INF Treaty and the end of cold-war ideology.

Child labor in the U.S. economy declined significantly between 1880 and 1920. This case study of the fruit and vegetable canning industry examines variations in laws, technology, and income across states and time to assess the relative importance of legal and economic factors in reducing the employment of children. The authors find that economic factors, especially a technologically driven shift toward a greater demand for adult labor, were relatively more important. While economic development was often a precondition for legal restrictions on child labor, compulsory schooling and child labor laws restricted the employment of children in technologically backward canneries.
