PRICE COMPETITION UNDER COST UNCERTAINTY: A LABORATORY ANALYSIS

We study the relation between the number of firms and price-cost margins under price competition with uncertainty about competitors' costs. We report an experiment in which two, three, and four identical firms repeatedly interact in this environment. In line with the theoretical prediction, market prices decrease with the number of firms, but on average stay above marginal costs. Pricing is more aggressive than in equilibrium. Absolute and relative surplus increases with the number of firms. Total surplus is close to the equilibrium level, because enhanced consumer surplus through lower prices is counteracted by occasional displacements of the most cost-efficient firm.

AIRLINE PRICING BEHAVIOR UNDER LIMITED INTER‐MODAL COMPETITION

This paper empirically analyzes airline pricing for short‐haul flights in contexts with no credible threat of inter‐modal competition. To this end, we explore the southern Italian market since it is less accessible by other transport modes and thus fares are the direct outcome of air‐related competition. We show, in fact, that market power matters, depending on the level of intra‐modal competition, and that airlines apply differentiated mark‐ups. Besides, consistent with the implementation of inter‐temporal price discrimination (IPD), we find a non‐monotonic inter‐temporal profile of fares with a turning point included in the interval of the 43rd to 45th days before departure. Finally, we provide evidence that in more competitive markets, airlines are more likely to engage in IPD. (JEL L11, L13, L93)     

COMPETITION AND TEACHER PAY

Competition‐based school reform could have a significant impact on teacher earnings. If school districts behave as typical oligopsonists, then increased competition could lead to higher salaries. However, if teachers receive a share of the economic rents generated by the monopoly power of school districts, then increased competition could lower teacher salaries. This study uses panel data from 670 Texas school districts and more than 335,000 teachers to examine the relationship between school competition and teacher pay. The analysis suggests that an increase in competition results in higher wages for most teachers but lower wages for teachers in relatively concentrated markets. (JEL I2, J3)     

FOREIGN TRADE AND DOMESTIC COMPETITION

This paper contains estimates of the determinants of the commodity composition of U. S. trade flows and of price-cost margins in U. S. domestic manufacturing in a simultaneous context. Above-competitive profits in U. S. manufacturing appear to provide a powerful incentive to import competition. These imports, in turn, provide a check on the ability of domestic firms to earn monopoly rents. The estimates indicate that failure to account for imports leads to a substantial underestimation of the impact of market structure on price-cost margins. The linkages between exports and domestic market conditions appear to be of second-order importance.     

SURVIVING CREDIT MARKET COMPETITION*

Empirical studies have documented that improvements in credit supply have important effects on entry in nonfinancial industries. This article shows that changes in credit supply conditions have much deeper effects on firms' population dynamics, well above and beyond the experience of entry. I explore the hypothesis that changes in credit supply have important effects on the demand side as well. I conjecture that when financial capital is difficult to obtain, while fewer firms may enter, those entering are drawn from a population with a better distribution of entrepreneurial quality. In an environment where financial capital is easily obtainable instead, the population of loan applicants changes as well, including those in a tougher environment who would not have tried entrepreneurship in the first place. These changes in the population of applicants imply significant effects on firms' life expectancy profile, and these effects are heterogeneous across firms of different vintage. Modifications in life expectancy are likely to affect firms' incentives in undertaking future capital investment and likewise investments in technological innovation. Hence, these changes in overall firms' population dynamics characterize an explicit mechanism through which finance can affect real economic activity. (JEL G21, L11, L16)     

IMPERFECT COMPETITION AND BASING-POINT PRICING

This article investigates the relationship between imperfect competition and basing point pricing. Basing-point pricing can emerge if firms at the base site are Bertrand competitors, firms at non-base locations are less than perfectly competitive with each other and are von Stackleberg leaders with respect to base site production, and the products produced at the base and non-base locations are perfect substitutes. Basing-point pricing is associated with competitive prices by base site firms but with markups by non-base site firms equal to their phantom freight charges.     

BERTRAND COMPETITION WITH ASYMMETRIC MARGINAL COSTS

This article tests the prediction of three discrete asymmetric duopoly price competition games in the laboratory. The games differ from each other in terms of the size of the cost asymmetry that induces a systematic variation in the difference between the firms' marginal costs. While the standard theory requires the low‐cost firm to set a price just equal to the high‐cost firm's marginal cost, which is identical across all three games, and win the entire market, intuition suggests that market price may increase with a decrease in the absolute difference between the two marginal costs. We develop a quantal response equilibrium model to test our competing conjecture. (JEL L11, L12, C91, D43)     

IMMIGRATION,SKILL HETEROGENEITY,AND QUALIFICATION MISMATCH

We investigate the effects of U.S. immigration in a comprehensive search and matching framework that allows for skill heterogeneity, imperfect substitutability between skilled and unskilled inputs, different search cost between natives and immigrants, cross‐skill matching, and imperfect transferability of foreign human capital. When we simulate the effects of the U.S. immigration that took place between the years 2000 and 2009, we find that both skilled and unskilled natives, as well as skilled and unskilled immigrants, gain in terms of income and employment. We also investigate the effects of an improvement in the transferability of human capital across borders and find that, although it has some redistributive effects, overall it benefits both immigrants and natives. (JEL F22, J61, J64)     

FIRM HETEROGENEITY AND THE PATTERN OF R&D COLLABORATIONS

We consider an oligopoly setting in which firms form pairwise collaborative links in research and development with other firms. Each collaboration generates a value that depends on the identity of the firms that collaborate. First, we provide properties satisfied by pairwise equilibrium networks and efficient networks. Second, we use these properties in two types of situation: (1) there are two groups of firms, and the value of a collaboration is higher when firms belong to the same group; (2) some firms have more innovative capabilities than others. These two situations provide clear insights about how firms' heterogeneity affects both equilibrium and efficient networks. We also show that the most valuable collaborative links do not always appear in equilibrium, and a public policy that increases the value of the most valuable links may lead to a loss of social welfare.

ANTITRUST and COMPETITION, HISTORICALLY CONSIDERED

Although antitrust laws enjoy wide support among economists, there was almost no such support during the early years of the Sherman Act. One reason for this transformation is a change in the theory of competition. Until the 1920s most economists viewed competition as a dynamic, rivalrous process that would be stifled by antitrust laws. Once the perfect competition model–which largely ignores rivalry–was accepted, economists' opinions of antitrust grew more favorable. To the extent that antitrust interferes with rivalry and enterprise, the competitive model has very likely misdirected the profession, at least as far as antitrust policy is concerned.     

SPATIAL COMPETITION AND STRATEGIC FIRM RELOCATION

Firms compete spatially for customers who have some degree of brand loyalty. The number and attractiveness of the alternatives available to these customers dictates the level of competition facing firms. In this study, data on ticket pricing in four professional sports leagues are used to empirically examine the existence of spatial competition in sports, and the impact of space on team relocations. Results, allowing for structural breaks over time while using spatial autoregressive techniques, suggest that sports franchises spatially compete when pricing their tickets, and that spatial characteristics, including the level of spatial competition, have influenced the relocation of teams. (JEL D40, L11, R30, L83)     

THEORY AND EXPERIMENTS ON SPATIAL COMPETITION

We present theoretical and experimental results on spatial competition between two firms. Firms choose locations simultaneously along a line representing a linear market. Identical consumers with non-increasing demand functions are uniformly distributed along this line. We solve for symmetric equilibrium payoffs in an infinitely repeated game for the case of linear demand and an arbitrary discount factor. The set of equilibriums found includes both competitive and collusive payoffs. In laboratory experiments in which the final period was unknown to the players in advance, we observed both competitive and collusive outcomes. Non-binding communication led to collusion.     

INTERNATIONAL TAX COMPETITION AND THE DEFICIT BIAS

I analyze the dynamic effects of tax competition on public budget deficits. I find that stronger tax competition leads to a fiscal deficit bias at the early stages of financial liberalization. When countries differ in terms of capital mobility, further liberalization leads to external imbalances and diverging fiscal deficits while corporate tax rates converge. Consistent with theory, I find that stronger tax competition increases deficits in a sample of OECD countries, controlling for tax revenues and other standard determinants of fiscal deficits.

COMPETITION AND THE CIGARETTE TV ADVERTISING BAN

The 1970 ban on television advertising for cigarettes constitutes a quasi-experiment allowing the effect of advertising on competition to be evaluated. Assuming the ban reduced the efficacy of industry advertising, an analysis of various proxies for competition before and after the ban enables one to deduce whether advertising promotes or limits competition among cigarette firms. The results indicate that in this case the restriction of advertising reduced competition.
