Microeconomic influences on operating leverage

The concept of operating leverage generally has been visualized in the context of linear break-even analysis. This paper evaluates the properties of two measures of the degree of operating leverage using a more general short-run microeconomic model of the firm. In this model, the degree of operating leverage is related positively to the price elasticity of demand for a firm's output, to its elasticity of supply for an input, and to its output elasticity. In addition, operating leverage measures are usually derived from models inconsistent with firm wealth maximizing behavior and are too simplistiic for complex models with stochastic demand, supply, and production functions.     

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.     

Form and content of replacement cost information: The impact upon investment criteria

The Securities and Exchange Commission (SEC) has recently required that certain registrants disclose specific current replacement cost information when filing their 10-K's. In the current research, unsophisticated investor surrogates were asked to perform an investment task using historical cost and/or variations of actual current replacement cost data for several companies. It was found that neither the content nor the form of the alternative information sets significantly affected the investor decisions.     

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.     

Increases in energy prices,costs of production,and plant size

A translog cost function is estimated for U.S. manufacturing in order to investigate plant size differences in responses to increases in energy prices. Smaller plants were more intensive users of energy in the early 1970s but were also better able to substitute out of energy and into other inputs during the first round of energy price increases. As a result, by the mid-1970s larger plants had become more intensive energy users. Thus, later energy price increases probably had a greater adverse impact on the production costs of larger plants in manufacturing.     

Comparison processes in task perceptions,evaluations, and reactions

The primary objective of this article is to present a social comparison model of how employees perceive, evaluate, and react to tasks. The model represents a synthesis of recent findings in the task design area and three social comparison theories. A three-stage process is described which suggests that employees first understand their tasks at an informational level, then understand their tasks at an evaluative level, and finally react to their tasks both affectively and behaviorally. Managerial implications and future research directions are discussed.     

Uncertainty,organizational form,and x-efficiency

When the firm is uncertain about the efficiency units of labor that it employs, some organizational forms—franchise, owner-operated, and multiplant firms— may be more profitable than others. As a result, particular organizational forms may dominate an industry with uncertain inputs. Conversely, various organizational forms may be selected by a company selecting producing units that will maximize the decision maker's expected utility of profits. This paper offers an alternative view of firm attributes associated with x-efficiency.     

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.     

A “Pure” long-term interest rate and the demand for money

This article presents the appropriate rate by which to discount a constant, certain, infinite stream of future payments: that is, the yield on a noncallable perpetuity or consol. The American consol series is a daily risk-free “pure” long term interest rate which is undistorted by tax effects, call premiums, and varying duration and reinvestment assumptions. If Hamburger had used the American consol series instead of the U.S. Government Long Term Bond Rate in his money demand function, he would have found more of the “missing money.” His average error (actual minus predicted money demand) as a percentage of actual money demand would have been reduced from 1.43% to 0.93% a 35% error reduction.     

Bargaining in distribution channels

This study empirically assesses the impact two fundamental dimensions of distribution channels have on channel member bargaining behavior, namely, (1) the expected duration of the channel bargaining relationship and (2) the channel member dependence on the bargaining. The following findings were observed from a laboratory study using 160 business students: low dependence produced fewer bargaining sessions ending in agreement compared to high dependence among buyer-seller dyads. Low dependence bargainers made more extreme initial offers, conceded less, and used the pronoun we less than did high dependence bargainers. The sellers emerged better off than the buyers from the negotiations. Sellers achieved this advantage by making more extreme initial offers than buyers, conceding more than buyers, but emerging with the better deal.     

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.     

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.     

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.     

The determinants of occupational mobility patterns among blue-collar jobs

Barriers to mobility are commonly believed to partition blue-collar jobs into skilled, semiskilled, and unskilled components. This paper develops a model based in large measure on the classical gravity model for purposes of ascertaining mobility pattern determinants and for testing for the presence and form of mobility barriers. The model is implemented on a 1965–1970 sample data of male mobility among 60 intermediate-detailed blue- collar occupations. The empirical results reveal that mobility patterns in the blue-collar component conform well with neoclassical theoretical expectations. Very little support is found for the view that the blue-collar labor market is highly structured or segmented in its operations through the mobility process.     

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.     

Automatic adjustment clauses and allocative efficiency in public utilities

This paper presents a formal analysis of the efficiency effects of automatic adjustment clauses (AACs) is regulated industries. Using a two-input model of ex ante/ex post input choice and a general putty-clay technology, we analyze the relative extent of allocative distortions due to each of three alternative regulatory policies—periodic rate review with and without an AAC, and an AAC without any rate review—for the case of a regulated firm that chooses an ex post technology to maximize the present value of future profits.Our results indicate that the economic rationale for using AACs in industries already subject to intermittent rate review is not unambiguous, even in the face of severe cost inflation, and is particularly sensitive to the magnitude of the price elasticity of demand for output and the rate and direction of input price changes. We are forced to conclude that the use of AACs in regulated industries such as electric power, while originally justified on the basis of financial viability, may well carry significant economic costs in the form of allocative inefficiency that may outweigh the benefits.     

Sales: Demand-supply variation or price discrimination?

The objective of this paper is to test the relative importance of price discrimination as an explanation for sales on major appliances. Using data on sales by Sears stores in San Diego, we conclude that for major appliance sales, price discrimination seems to be the most important explanation. The second section describes briefly the theoretical explanations for sales. The third section describes the test and the results. The fourth section presents more stylized facts about appliance sales. The last section presents the conclusion.     

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.     

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.
