Concentration and Market Structure in Local Real Estate Markets

The competitiveness of the residential real estate brokerage industry has attracted much attention. Anecdotal evidence suggests some local markets are concentrated, yet no systematic market structure study has been conducted. We collected cross‐sectional data on real estate brokers in 90 diverse markets across the United States and collected longitudinal data for Louisville, Kentucky. In medium and large markets, no evidence exists that market concentration might create problems for competition. Small markets, on average, have higher Herfindahl‐Hirschman Indexes than medium and large markets. The longitudinal data reveal that many small brokers sell a house or two one year and none the next year.     

Entry in Local Telecommunication Markets

In this paper, we explore the determinants of recent entry into local exchange service, and the role that regulatory policies have had in aiding this policy objective. Our results suggest that the 1996 Telecommunications Act did lead to some entry, but that strategic non-price behavior by incumbents may have offset this impact to some extent. We also find that regulatory policies and market fundamentals play an important role in determining entry. Clearly, market size (measured in various ways) is an important determinant of entry, while there is empirical support for the role of more flexible regulatory mechanisms in promoting new entry.     

A New Perspective on Entry in Horizontal Merger Analysis

I analyze horizontal mergers in procurement settings in which sellers incur costs to participate. Considering existing sellers’ contest-level entry differs from antitrust authorities’ typical emphasis on new sellers’ market-level entry to counteract a merger’s anticompetitive harm. I show that profitable mergers can increase consumer and total surplus by inducing more and stronger contest-level entry by the merged seller, which echoes common claims from merging parties that their merger is beneficial because it creates a stronger competitor. This finding suggests caution by antitrust authorities: when contest-level entry costs matter, standard models that ignore those costs prescribe blocking procompetitive mergers.

Price Controls and Market Structure: Evidence from Gasoline Retail Markets

In this paper we study the effect of price floor regulations on the organization and performance of markets. The standard interpretation of the effects of these policies is concerned with short‐run market distortions associated with excess supply. Since price controls prevent markets from clearing, they lead to higher prices. While this analysis may be correct in the short‐run, it does not consider the dynamic equilibrium consequences of price controls. We demonstrate that price floor regulations can have important long‐run effects on the the structure of markets by crowding them and creating endogenous barriers to entry for low‐cost retailers. Moreover, we show that these factors can indirectly lower productivity and possibly even prices. We test this in the context of an actual regulation imposed in the retail gasoline market in the Canadian province of Québec and show that the policy led to more competition between smaller/less efficient stations. This resulted in lowered sales, and, despite the reduction in efficiency, did not increase prices.     

Market Definition and the Merger Guidelines

The recently issued revision of the US Horizontal Merger Guidelines, like its predecessors and mirrored by similar guidelines throughout the world, devotes substantial attention to the market definition process and the implications of market shares in the market that is selected. Nevertheless, some controversy concerning the revised Guidelines questions their increased openness toward more direct, economically based methods of predicting the competitive effects of mergers. By contrast, this article suggests that, as a matter of economic logic, the Guidelines revision can only be criticized for its timidity. Indeed, economic principles unambiguously favor elimination of the market definition process altogether.

Pseudo-Generic Products and Barriers to Entry in Pharmaceutical Markets

This paper examines incentives for brand-name pharmaceutical producers to market pseudo-generic versions of their own branded products upon the expiry of patent protection.Using a two-stage game model, we determine that under plausible demand and cost conditions, brand-name incumbents can find it profitable to produce pseudo-generics as a means of blocking rivals' entry even when independent firms producing true generics face low entry costs.The model shows that social welfare can be higher when firms use pseudo-generics instead of capacity for entry deterrence as long as substitutability between brand-name and generic products is sufficiently high.     

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.     

Entry into Swedish Retail and Wholesale Trade Markets

This paper examines, using a zero-inflated negative binomial regression model, what determined entry into the Swedish retail and wholesale trade markets between 1990 and 1996. According to the results, high returns on equity and low sunk costs seemed to attract more entry into retail trade industries, while recent entry and higher total industry sales were associated with more entry into both retail and wholesale trade local markets.     

Switching Costs in Vertically Related Markets

In the presence of switching costs, firms are ofteninterested in expanding current market shares toexploit their customer base in the future. However, ifthe product is sold by retailers, manufacturers mayface the problem of extracting too much surplus fromthe retailer. If this happens, then the latter has notan incentive to build a subscriber base. This paperwould like to connect two streams in the literature,on switching costs and vertical restraintsrespectively. An upstream–downstream duopoly model ispresented to analyse the mutual incentive for firms toenter into particular trading relationships. Whenswitching costs are high, then integrated structuresare predicted. On the other hand, when lock in effectsare not too relevant, mixed structures withindependent and integrated firms emerge as anequilibrium in growing industries. The results arediscussed with reference to the UK mobiletelecommunications industry.

Differential Pricing in Intermediate Good Markets

This paper studies differential pricing by an upstream monopolist whose cost to supply the intermediate good differs across buyers in the downstream. It is shown that, different from demand‐based price discrimination, cost‐based differential pricing shifts production efficiently. If total output (and consumer welfare) is weakly increased under differential pricing as opposed to uniform pricing, as is true for weakly convex final market demand functions, social welfare is strictly improved. The analysis is extended to the case in which both the upstream monopolist's cost to serve the downstream firms and the downstream firms’ cost to produce the final good differ.     

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.
