A note on the market share-profitability relationship

This study extends earlier empirical work to determine whether there is a breakpoint or critical level in the frequently observed relationship between firm market share and profit rate. The analysis focuses on the banking industry and uses a sample of 10,690 firms located in 2165 different local geographic markets. Though the results apply directly only to banking, the similarity of findings on various other industrial organization topics in banking and the industrial sector suggests that the results of this study will be broadly relevant to the industrial sector.The main findings of the study are that (1) in general, firm market share is directly related to profitability; (2) the firm market share variable remains positive and significant when controlling for market concentration either with concentration as a separate independent variable or by conducting tests with subsamples of firms that are in markets with similar concentration ratios; and (3) while there is no sharp breakpoint in the market share-profitability relationship, the results indicate that profit rates of firms increase at a decreasing rate up to a share of about 55 percent. Since numerous studies have found that economies of scale are not particularly important in banking, it appears that the observed relationship is not due to greater efficiency with larger shares.     

Market Share Inequality,the Number of Competitors,and the HHI: An Examination of Bank Pricing

This paper seeks to determine whether the Herfindahl--Hirschman index (HHI) adequately accounts for the roles of market share inequality and the number of competitors in explaining bank deposit and loan rates. This is been done by estimating deposit-rate and loan-rate equations in which the HHI is decomposed into components that reflect share inequality and number of competitors and, alternatively, by adding measures of share inequality and the number of competitors as additional explanatory variables. Results are inconclusive in the case of deposit rates but suggest that the HHI does not give sufficient weight to the number of competitors in explaining loan rates.     

Structure and Profitability in Banking Markets

We use the structure-performance model and regression analysis to investigate a number of analytical issues that often arise in evaluating competition in connection with bank mergers and that are generally relevant to mergers in other industries. Perhaps our most consistent and strongest finding is that the local market HHI is positively and significantly related to profitability. We also find that the number of organizations and the level of recent deposit growth may provide some additional information on the level of competition. Finally, several variables including market size, the number of large banking firms, deposits per office, and resident migration rates exhibit similar relationships to profitability in the bivariate analysis, suggesting that there may be some characteristic associated with market size, density, or attractiveness that is important for competition.     

Does the ‘persistence of profits’ persist?: a study of company profits in Japan, 1964–97

Earlier, in a time-series study of the profit rates of Japanese manufacturing firms, Odagiri and Yamawaki concluded that profits persist. With the addition of 15 more years of data up to 1997, this conclusion is shown to stand the test of time. In particular, those firms estimated to earn higher-than-average long-run profit rates in the early study were again estimated to earn higher-than-average long-run profit rates. The force of convergence was also found to be at work; for instance, the firms most profitable in Period 1 (1964–82) were most likely to face a decline in estimated long-run profit rates from Period 1 to Period 2 (1983–97). With the use of two sets of data, the firm’s profit performance was found to be positively related to measures of market share. First, among a smaller sample of firms for which reliable market share data could be matched, market share was estimated to have a significant positive effect on long-run profit rate in either period. Secondly, among the entire sample of 357 firms, the long-run profit rate in either period was estimated to be positively associated with firm sales relative to industry sales, which presumably is a crude measure of market share.     

Market structure and market outcomes in deregulated rail freight markets

Using cross-section data on a national sample of city-pair markets for rail freight, I examine correlations between prices, quantities, and the number of single-line and interline firms serving markets. I estimate the reduced form of a structural model in which rail rates and quantities depend on the number of firms. I find that rates increase as the number of firms serving the market falls, and quantities shipped rise as the number of firms falls. The result is consistent with market power for rail freight shippers that causes markups to rise when fewer firms serve the market, and is not consistent with other explanations of the relationship between number of firms and rates and quantities. Interline shipment is much more costly than single-line, suggesting that mergers may be desirable even if they exacerbate market power problems.     

Global corporate competition: Who's winning,who's losing,and the R&D factor as one reason why

This study summarizes the major changes over the period 1960–86 in the shares of world markets of the world'S leading American, European and Asian corporations based in 15 major industries. It relates the differential sales growth rates of the gaining and losing firms to national trends in industrial competitiveness, to employment change and to long-term returns to shareholders. One principal determinant of firms' global growth rates, and thence gains and losses in ‘world market share’, corporate research and development (R&D) intensity, is examined and tested on an 83-firm, six-industry subset of the overall data base. The proportion of corporate sales revenues allocated to commercially oriented R&D emerges as a, perhaps the, principal indicator of subsequent sales growth performance relative to competition over 5–10-year periods. Insofar as many U.S. and U.K. firms have lost global market share relative to Asian and European competitors over the past two decades, a significant contributory factor would appear to have been negligence on the part of many U.S. and U.K. firms of investment in technology as a factor determining strategic, competitive advantage.     

Strategy,structure and performance of major U. S. Oil companles: Evidence from line of business data

In this paper we assess the influence of size, market share, and vertical integration on upstream (oil and gas production) and downstream (refining and marketing) profit rates for twenty-five large petroleum companies. We use pooled time series and cross section line of business data collected by the Financial Reporting Service of the Energy Information Administration. We employ a fixed effects model which allows for firm specific characteristics and a proxy variable to control for firm efficiency. We find that firm structure has differential impacts on performance between upstream and downstream lines of business and that lending firms are differentially impacted by structural variables, compared to other firms in the industry. Firm specific factors are also found to be significant determinants of profit raten.     

On commodity taxation in vertically differentiated markets

We examine the impact of commodity taxation on vertically differentiated product markets when entry is allowed. We show that an ad valorem tax may have a dramatic effect on market structure by inducing the entry of a large number of firms in what was previously a natural monopoly. The producers of high quality products reduce market share after an increase in their unit production cost, leaving more room for lower quality products. While within a given market structure aggregate quality decreases monotonically with the tax rate, quality jumps upwards at tax rates that cause a change in market structure.     

INEFFICIENCIES AND MARKET POWER IN FINANCIAL ARBITRAGE: A STUDY OF CALIFORNIA'S ELECTRICITY MARKETS*

For two years prior to the collapse of California's restructured electricity market, power traded in both a forward and a spot market for delivery at the same times and locations. Nonetheless, prices in the two markets often differed in significant and predictable ways. This apparent inefficiency persisted, we argue, because most firms believed that trading on inter‐market price differences would yield regulatory penalties. For the few firms that did make such trades, it was not profit‐maximizing to eliminate the price differences entirely. Skyrocketing prices in 2000 changed the major buyers' (utilities') incentives and exacerbated the price differentials between the markets.     

Determinants of Entry and Profits in Local Banking Markets

This paper estimates a two equation model of market entry and profits, utilizing data on entry into over 2,000 banking markets over the period 1977--88. The entry equations measure whether entry depends on incumbent firms' profits and other market attributes that reflect the long-term attractiveness of markets for entry. Market profits, assumed to follow a partial-adjustment process, are affected by entry directly and indirectly through market structure. The model also corrects for an unavoidable source of error in market-level profits for the banking industry. The estimates suggest that a competitive process is at work in banking markets that limits the ability of supra-normal profits to persist. Entry is more likely in markets that have high profits, consistent with previous empirical results that market structure adjusts more quickly when profits are supra-normal. Population and population growth are also strong determinants of entry. Entry, in turn, reduces profits in rural markets.     

The licensing dilemma: understanding the determinants of the rate of technology licensing

The licensing of technology entails a trade‐off: licensing payments net of transaction costs (revenue effect) must be balanced against the lower price–cost margin and/or reduced market share implied by increased competition (profit dissipation effect) from the licensee. We argue that the presence of multiple technology holders, which compete in the market for technology, changes such a trade‐off and triggers more aggressive licensing behavior. To test our theory, we analyze technology licensing by large chemical firms during the period 1986–96 for 107 chemical products. We find that the rate of technology licensing displays an inverted U‐shaped relationship with the number of potential technology suppliers and is negatively related to the licensor's market share and to the degree of technology‐specific product differentiation.

Equity‐based incentives and collaboration in the modern multibusiness firm

Research summary : This paper examines the role of equity‐based incentives in fostering cross‐business‐unit collaboration in multibusiness firms. We develop a formal agency model in which headquarters offers equity and profit incentives to business‐unit managers with the objective of maximizing total expected firm returns. The resulting compensation contract provides a rich mechanism for aggregating value from collaborative interactions across business units, aligning managers' efforts with the firm's growth prospects and organization structure and managing the dual risks in profits and firm market value. The inclusion of equity incentives elicits higher levels of own‐unit and collaborative efforts over the profits‐only contract. Our results suggest that equity‐based incentives are most beneficial when profitability is uncertain relative to long‐term growth prospects, in firms pursuing related diversification strategies, and in periods of rising equity markets. Managerial summary : Equity‐based compensation such as restricted stock grants and options are increasingly common, not only for CEOs and other top executives, but also for business unit managers and other non‐C‐suite employees. The paper studies the role of such “global” incentives in enabling multibusiness firms to benefit from cross‐unit collaboration. Results from our model show that managerial contracts that include appropriate levels of equity incentives, in addition to profit‐based incentives, generate higher own‐unit and collaborative efforts. We also find that equity incentives are likely to be most beneficial for large firms in high‐growth sectors, for firms pursuing a related diversification strategy, and in periods of rising stock markets. The model can also provide useful guidance on designing return‐maximizing compensation contracts for business unit managers in different firm, organizational, and industry contexts.

Regime Effects of EU Market Integration Policies on the UK Financial Sector

Standard equity capital market methods are used to estimate the share price effects in the UK market of the recent change in regime implied by passage of key provisions implementing the European single banking market. Empirical results indicate that events associated with increasing the likelihood of passage of the new Merger Control Regulation and the Second Banking Directive had positive valuation effects for the portfolio of UK firms involved in banking services.     

Surviving the gales of creative destruction: the determinants of product turnover

Innovative industries are often characterized by rapid product turnover. Product longevity may be driven by both a product's position within a market as well as its position within a firm's larger product portfolio. However, we have little understanding of the relative importance of these factors in determining product turnover and how they interact as an industry evolves. Although researchers have invested substantial effort in analyzing firm survival and turnover, there are far fewer studies of the determinants of product survival and turnover. We use hazard rate models and count regression models to describe the behavior of firms and their products with a new and detailed database on the laser printer industry. We show, first, that competition and market structure variables have a large impact on both speeding product exit and delaying product entry. Second, there is some evidence that firms that have maintained a high market share for a number of years keep their products on the market longer than those with lower market share. Finally, firms with high innovative capacity tend to enter markets frequently, but withdraw their products at average rates. Firms with strong brands tend to introduce few products and withdraw their products slowly. With these findings, the paper links product entry and exit decisions to the broader literature on firm strategic and product management. Copyright © 2006 John Wiley & Sons, Ltd.     

Market Share in the Real Estate Brokerage Industry

This paper is concerned with the factors that determine the market share of listings and the market share of sales for brokerage firms. Models are developed and tested in a SMSA that conveniently corresponds exactly to a particular Multiple Listing Service area. Indices of firm specialization and market concentration were computed in addition to more conventional characterizations of the market and the data used in the study.
The regression results reveal a small degree of consistency in the impacts of the explanatory variables over the two years of the study and over the listing and sales markets. The number of salespeople is the most consistently significant variable. Indeed, market share per salesperson appears to be a non-monotonic function of the number of salespeople. The presence of a franchise and the quantity of display advertising are occasionally significant. Classified advertising, Yellow Pages advertising, and open houses all do not significantly affect market share per salesperson.     

Multimarket contact and sales growth: evidence from insurance

Research on pricing, profits, and firm survival has shown that multimarket contact causes mutual forbearance against competition, but has not considered the consequences of imperfect observability of competitive moves. Here, predictions are developed to explain how mutual forbearance occurs—but sometimes fails—in markets with imperfect observability. Mutual forbearance means that firms do not seek to take market share from each other through price cuts or nonprice competition, and thus that sales grow at uniform rates. Firms defect from mutual forbearance, and hence have higher sales growth, if the potential rewards are high and the likelihood of being discovered is low. This theory is tested on a panel of firms operating in the Norwegian general insurance industry. The evidence suggests that sales growth is most rapid in firms that do not meet many multimarket competitors in a given market and firms that are economically troubled. Growing or highly concentrated markets have higher heterogeneity of growth rates. Copyright © 2007 John Wiley & Sons, Ltd.     

The independent submarkets model: an application to the Spanish retail banking market

The aim of this paper is to test the predictions of Sutton’s independent submarkets model with data on the Spanish retail banking market. The prediction of this model for aggregates of submarkets is that the form of equilibrium outcome must involve some minimal degree of size inequality. However, within each submarket, when three conditions hold, the only form of equilibrium outcome will be an extreme ‘fragmented’ structure. To test these predictions, firstly I propose methods to identify independent submarkets. Then I analyze the degree of inequality in bank sizes for markets with different levels of aggregation (submarkets, regions and national market). Using concentration by towns’ data, I find that in single submarket towns the degree of inequality of the size among banks is zero. Moreover, multimarket towns with a significant degree of concentration are shown to be formed by a different number of independent submarkets where each bank owns one branch. Nonetheless, when the regional and the national bank markets are considered, the degree of inequality in bank sizes becomes high. These results are consistent with the predictions of the theoretical model.     

Potential competition and the factors influencing banking concentration

Multiple regression analysis is used to study the factors influencing market concentration in urban banking markets. The results indicate that independentde novo entry and shifts in population from the central city to the suburbs can be important deconcentrating factors in urban banking markets. In terms of the potential competition doctrine, the results suggest that attractive banking markets are likely to attract enough actual and potential entrants to mitigate any problems associated with a leading bank acquisition by a potential entrant. On the other hand, potential competition is more likely to be an issue in less attractive banking markets where the probability of entry is low.     

Research notes and communications first-mover effects in multiple dynamic markets

A study of first-mover effects in semi-submersible oil-drilling suggests that first-entrants in international markets maintain higher market share after controlling for market localization and life cycle. Examining only surviving entrants at a point in time inflates this pioneering-market share relationship. Pioneering has an inter-market effect on market share, greater than the intra-market effect. Multinational firms may use market pioneering to resist localization pressures and enhance survival in foreign markets. The study suggests the importance of careful first-mover identification and market definition, a wider examination of first-mover effects over multiple markets, and control for measurement timing.     

Characteristics of Innovative Firms in the Brazilian Computer Industry

A number of studies have reported characteristics of innovative firms; however, these studies have typically been conducted in freely competitive markets. Angela da Rocha, Carl Christensen and Newton Paim have studied firms within the Brazilian computer industry. The Brazilian government regulates the entrance of foreign competitors to this market. Thus, the authors are able to ask whether the characteristics of innovative firms in a protected market differ from characteristics previously reported in competitive markets. With only a few minor exceptions, the reported profiles of innovative firms are quite similar. These results suggest that characteristics of innovative firms are generalizable across certain industry and environmental conditions, including protected markets.
