Scale economies,entry, and welfare

This study shows how scale economies, initial size differences among firms, potential competition, and adjustment costs may influence the entry of firms into a dynamic oligopoly. It also examines the effects of these factors on the final size distribution of firms in an industry, and on the welfare levels of consumers and producers. We find that low to moderate scale economies are insufficient for Cournot-Nash competition to drive small firms from the market. Only when scale economies are quite high will the distribution of firm sizes become degenerate. Potential competition and the size of incumbent firms' capital stocks are additional barriers to entry. The welfare conclusion is that there may be a government role to preserve potential competition, but also to dissuade small firms from entering certain markets where there are economies of scale.     

The determination of corporate optimal capital structure under value maximization and informational asymmetry

In this article we examine the optimal capital structure of the firm under conditions of informational asymmetry, i.e., when the manager of the firm is viewed by the market as possessing inside information about the firm's future profitability. Unlike previous research on this topic, in this study we preserve the objective of value maximization when examining the signaling property of corporate capital structure. We also recognize explicitly the other consequences of debt financing on the value of the firm. An integrated analysis of the capital structure problem within the context of rational expectation is presented, and a signaling equilibrium is derived and discussed. The nature of the welfare costs that emerge from the existence of informational asymmetry is also analyzed.     

The optimal size of the competitive firm

In this article a simple derivation of the optimal long-run size of the competitive firm is given under general assumptions about the organization of the enterprise, and in a world where production occurs only under constant or increasing returns to scale. To do this, only the basic notion of a firm as some form of central coordinating agency is relied on.     

The optimal policy rule under rational expectations and multiplier uncertainty

This paper shows the role of macro policy under multiplier uncertainty when expectations are rational and the supply structure is affected by price level variance. Policy less is a function of price level variance and possibly of the expected price level. If the letter argument is omitted from the less function, optimal policy simply minimizes the horizontal variance of the aggregate demand curve. If it is not omitted, the level of policy depends on the responsiveness of the supply structure to price level variance, and there may be multiple local policy optima.     

Labor market differentials and the expected gain from search

Several recent empirical studies have used the residuals from estimated earnings equations as explanatory variables in models of on-the-job search and quit behavior. It has often been argued that the coefficients on these “market differential” variables are biased downward because estimated residuals overstate the “true” quasi-rent or disincentive to search for alternative employment. This argument—that observed wages include implicit payments for workplace and person-specific characteristics not fully specified in earnings models— ignores an opposing bias associated with the value of being able to reject unattractive wage offers. As a consequence, there is no unambiguous a priori relationship between estimated wage residuals and the theoretical expected gain from search. Some evidence bearing on the relative magnitudes of the two biases is discussed.     

Some evidence on the role of money illusion in labor supply behavior

The Keynesian idea that workers are subject to money illusion in their labor supply decisions is tested by estimating a labor supply function that includes the price level as an independent variable. The model is estimated with data drawn from various BLS publications and is aggregated by SMSA. The results indicate a significant negative supply response to price-level changes after controlling for the nominal wage rate, income, and the SMSA's unemployment rate. There is no significant difference between workers' supply response to the price level and the nominal wage rate, which suggests that workers are not subject to money illusion.     

Regularity and diversity in firm size distributions in U.S. industries

The size distribution of firms in manufacturing industries has long been a matter of interest in industrial organization. Distribution in different industries show considerable regularity that static economic theory fails to explain. Stochastic growth models appear to provide some insights, but empirical tests of the log-normal or Pareto distributions have been inconclusive. This paper draws on market share data for over three hundred U.S. manufacturing industries and analyses the distribution of largest firm sizes. A statistical test of the Pareto hypothesis, rather different from previous tests in the literature, decisively rejects that hypothesis as a general explanation for the upper tail of the distribution. Instead, great diversity among distributions is found, and the regularities that do emerge imply a greater clustering of large firms than predicted by theory.     

Optimal dynamic behavior of a market maker in choosing bid and asked prices

Dynamic programming is used to describe a specialist's choice of bid and asked prices given uncertainty about both limit and market orders. The role of limit orders is emphasized. Optimal quotes depend on the composition of limit orders, the size of the specialist's position, and the time of day. The optimal bid-ask spread, however, depends only on the composition of the book. The capitalized value of the specialist's franchise is studied. Long-run probability distributions for bid and ask prices are obtained, which show that the variances of these prices increase as the end of the day approaches.     

Asset preference,skewness, and the measurement of expected utility

This article shows that serious analytical errors may occur in expected utility theory when Taylor series approximation methods are used without careful attention to underlying mathematical assumptions. Recent studies have developed theory incorporating skewness of return into expected utility calculations based on a Taylor series approximation. It is apparent that this theory is invalid if assumptions for application of a Taylor series cannot be met. Errors may occur if returns fall outside the region of convergence of the utility function ot if the partial sums of the Taylor series provide poor approximations to the utility function. Stylized examples are presented to illustrate miscalculation of utility when the various assumptions are violated. These examples are motivated by the use of Taylor series approximations in current literature which deal with the new spectrum of financial securities.     

Price adjustment strategy under conditions of high inflation: An empirical examination

Price adjustment strategy is a central problem to businesses operating under conditions of high inflation. Three different approaches to the problem are presented and some of their implications tested empirically by means of a unique data set. The empirical observations do not support any of the three traditional approaches.     

Multibank holding company activity and local market structure: Some implications for intra- and interstate banking

This paper presents new evidence on the effects of multibank holding companies on the structure of local commercial bank markets for deposits. A distinguishing feature of this study is the use of pooled cross-section and time-series data. It is concluded that multibank holding company activity has had a procompetitive effect on the local banking markets in the sample. This finding, which is quite robust under alternative model specifications, has important implications for state and federal policy toward this organizational form and toward intra- and interstate banking.     

Agency costs in banking firms: An analysis of expense preference behavior

Behavioral approaches to the theory of the firm contend that the agency relationship that must develop when a separation exists between management and ownership may have various agency costs. One such cost is the cost of monitoring managers to avoid expense preference behavior on their part. Managers may engage in expense preference behavior any time they manage firms in noncompetitive markets and ownership of the firm is dispersed enough to put control in the hands of management. This research reports on an analysis of the existence and influence of expense preference behavior on the salaries of chief operating officers of banks. Various studies have resulted in conflicting conclusions about the effect of expense preference behavior on various input costs facing banks. Only the study by Hannan and Mavinga (1980) includes an explicit measure of the separation of ownership from control of the firm. However, that study does not analyze executive compensation. Using such a measure, this study reports that the salaries of chief operating officers in banks are significantly higher if both the necessary and sufficient conditions for expense preference behavior are satisfied.     

Capital market efficiency and the relationship between equity returns, interest rates, and monetary aggregates in Australia

This paper examines the efficiency with which the Australian share market incorporates new information relating to interest rates and the monetary aggregates into share prices. It finds a strong relationship between medium term government security yields and equity returns although little relationship could be found between unanticipated changes in the monetary aggregates and share returns. Furthermore, the interest rate relationship involved long lags and suggests inefficiency in stock market pricing in Australia.     

Oil prices and world inflation

In this paper we attempt to address the nature of the causal relationships between oil prices and U.S. inflation. We use a procedure developed by Granger to assess “causality” or, more precisely stated, “informativeness.” Our results confirm that higher oil prices have increased the U.S. WPI. Our results also support OPEC's contention that their price increases have in part been a result of worldwide inflation.     

Polymorphism in competitive strategies: Trading stamps

This paper uses the example of trading stamps to examine a model of competitive nonprice marketing strategies. A concept borrowed from ethology, polymorphic equilibrium, is developed and used to explain salient features of trading stamp use by retail firms. The results contribute to an understanding of why virtually identical firms may optimally choose quite different competitive strategies. The paper also demonstrates the possibility of cyclical movements in the proportion of firms that adopt nonprice strategies such as the use of trading stamps.     

An econometric assessment of the Canadian wage and price control program: 1975:4–1977:4

This paper presents an econometric assessment of the Canadian Wage and Price Control Program. The assessment is specifically designed to determine whether controls have been effective in reducing the long-run inflation rate in Canada. The method of evaluation of the control program is to compare the behavior of inflation under controls to the behavior which would have occurred in the absence of controls. In addition, the paper analyzes inflation in the post-control period to test for the “catch-up” phenomenon. The results suggest that the control program exercised a permanent effect on the inflation rate.     

Price-Anderson act declared unconstitutional: The decision and its effects on nuclear power

In March 1977, the $560 million limit on liability in the Price-Anderson Act was declared unconstitutional. The Price-Anderson Act sets forth a combination private-public insurance and compensation system for handling risks associated with commercial nuclear operations. The limit was found to violate the due process and equal protection provisions of the Fifth Amendment of the U.S. Constitution. This paper examines the salient points of the decision which include: (a) the effects of nuclear plant operations on the plaintiffs; (b) the dependence of nuclear power development on the Price-Anderson Act; (c) the plaintiff's right to bring suit; and (d) the rationale for declaring the Act unconstitutional. The potential effects include the possibility that many utilities and suppliers of nuclear plant components will terminate their nuclear business, the availability of capital funds for nuclear plants will be reduced, and that cost of capital will be increased to reflect the greater risk of nuclear development.     

Bank structure and mortgage rates: Implications for interstate banking

Competition in financial markets has been the subject of many studies in the area of market structure and performance. This paper analyzes the differences in mortgage rates between unit banking and branch banking states to consider the likely outcome of interstate banking on competition. A model of interest rate determination is developed which suggests that, at least in the mortgage market, interstate banking will, ceteris paribus, decrease competition if it lowers the number of competing firms and increases deposit concentration levels. Support is provided for the argument that only those states under statewide branching laws may receive more competitive environments from the spread of interstate banking.     

Entry inclinations under uncertainty

This paper considers the market entry decision of a potential entrant that behaves as if it knew the future market demand and its own cost schedules, and formulates a set of probability judgements as to the unknown output rates that its future rivals will maintain. The special case where entry is free and each in-market seller, as well as the potential entrant, assumes that the others will not alter their production provokes the classic Cournot-Stackelberg situation. Although one might suspect that uncertainty would tend to inhibit entry as compared with an equivalent, in the expected-value sense, certainty situation, this is not at all the case. The suspucion is not necessarily true even when management is risk averse.     

The monetary explanation of inflation: The experience of three major OPEC economies

The purpose of this paper is to analyze and to test empirically the monetary explanation of inflation in the case of the moderate inflationary experience of three major OPEC economies over the last two decades. The estimated model takes into account the underlying money demand relationship and pays careful attention to the model's lag specifications. The empirical results show that the monetary model of inflation adequately explains the inflationary process in each of the countries studied. These empirical results, furthermore, are econometrically valid insofar as they are not plagued with significant simultaneous-equation bias. In addition, the estimated equations are also found to exhibit structural stability over time.
