Focusing on developments of the last twenty years, the author analyzes the achievements and the shortcomings of business history in Germany and offers some suggestions for its future.

At the end of World War II, by far the most significant pressure for integrating the aviation industry into national defense planning came neither from the major aircraft firms nor from the military. Instead, the Truman administration played the leading role in forging an important link in what later came to be called the “military-industrial complex.” Smaller businessmen and local politicians proved constant and eager supporters of that policy.

Utilizing data from a single state, Professor Keehn examines a number of important hypotheses about banking history and the role of banking in the process of economic growth and development in America from the Civil War to the creation of the Federal Reserve System.

Ceteris paribus, investors prefer to purchase municipal bonds selling close to their par value. That is, investors are willing to purchase at the lowest yield a municipal bond alike in all respects to other municipal bonds, but with a coupon that permits it to be sold at or near its par value. Conversely, investors are willing to purchase municipal bonds with coupons that cause them to be sold at prices either greatly above or greatly below par only at penalty or premium yields relative to similar par bonds.

There have been many efforts in recent years to explain differences in the performance of commercial banks. Interest has centered on the extent to which changes in a selected group of indices of bank performance are related to the structure of banking markets and selected other factors thought to influence bank behavior. While various techniques have been used, the most common has been multiple linear regression. The measures of performance entered into the regression equations have included the price and quantity of bank services and bank profitability, while the explanatory variables have included, to name only a few, the one-, two-, or three-bank concentration ratio, the number of banks in the market, the existence of competition from nonbank financial institutions, bank costs, bank size, and proxies for the demand for banking services. Generalizations then have been made about the impact of market structure and other variables on bank performance, generalizations based upon the regression coefficients of the explanatory variables. The consensus appears to be that the demand for banking services and bank costs are significant determinants of the performance of individual commercial banks; market structure appears to be much less important. However, the conclusions are by no means unanimous.

Professor Melicher has conducted an interesting study of the effects of financial factors on beta coefficients and their variations. He reduced the perennial multicollinearity problem by using a factor analysis to screen the financial variables used in the statistical analysis. This study is another in the growing body of literature concerned with beta coefficients as measures of risk. My comments on this paper will consider separately (1) the research design (i.e., what the study directly covered), and (2) the inferences drawn by the author versus what the beta coefficients and their variation really do measure.

The study initially examined the immediate effects that conglomerate acquisitions have on the beta level of conglomerate and nonconglomerate acquiring firms. An analysis was then made of the long-run beta trends of firms that actively engage in conglomerate mergers. The results of the short-term comparative analysis have indicated that systematic risk behavior tends to be responsive in varying degrees to major conglomerate merger activity—with betas changing as a function of the combined premerger values and ρ2 measures showing improvement upon acquisition. At the same time, the regression results clearly revealed that the responsiveness of β to premerger marketrelated variables was considerably greater for the nonconglomerate firms. In contrast, the results of the comparative long-term analysis suggested that the differential effects of conglomerate merger activity on systematic risk are more of a marginal or limited nature. That is, unless the firm conducted extensive merger activity, the long-run performance of β and ρ2 indicated that conglomerate mergers have only contributed to increased absolute and relative systematic risk levels—the same pattern exhibited by the nonconglomerate, nonmerging sample.

The purpose of this research is to develop a model for determining the credit worthiness of commercial loan applicants in a particular troubled industrial sector of France. The model is developed with the assistance of Banque de France, which serves tne central banking function in a banking environment that has become increasingly competitive in recent years. The research assesses the combined potential of traditional financial statement analysis with several relatively modern statistical procedures to aid the commercial loan officer.
