The legal framework of the EC single market

The European single market is underpinned by Community law, which is supreme and directly applicable in national courts. But the UK loses out because of disparities between national legal systems, and because Community law is interpreted to serve the political objective of European unity. There are several possible intermediates between full EU membership and complete withdrawal.
There is no legal barrier to the UK's exit from the EU should it wish to take that step.     

Import competition and market power: Canadian evidence

This study estimates price–marginal cost mark-ups for Canadian manufacturing industries during the 1970s in order to assess the impact of import competition on domestic market power. The results are mixed. Based on the analysis, there is no consistent evidence that imports reduced the mark-ups of Canadian firms during that period.     

Platform competition: Betfair and the UK market for sports betting

We examine two episodes of strategic interaction in the UK betting industry: (a) Betfair (an entrant multisided platform, or MSP) versus Flutter (also an MSP), and (b) Betfair versus traditional bookmakers. We find that although Betfair was an underfunded second mover in the betting exchange space, it was able to attract punters at a much faster rate than the better‐funded first mover, Flutter. Moreover, while Betfair and traditional bookmakers competed aggressively for market share, they also developed a highly complementary relationship that favored all parties. We discuss implications for research in the economics and management of MSPs. Specifically, we argue that the literature would benefit from work that endogenizes platform design and that considers the possible competitive and cooperative interactions between the business models of traditional incumbents and those of potential innovative MSP entrants.     

Labour market oligopsonistic competition: The effect of worker immobility on wages

We suggest that firms in a local labour market may be able to exploit worker mobility costs and offer immobile workers wages that are lower than their marginal product. If so, the ability of employers to exploit worker immobility in setting wages would decline in the competitiveness of the local labour market. We test this intuition using a measure of individual mobility costs and measures of local labour market competition. Our findings suggest that worker immobility causes substantial wage variation across workers in small, weakly competitive markets, and in occupations where wages are individually bargained.     

会计师事务所的进入、退出与审计市场的竞争

本文主要从进入、退出的角度研究审计市场的竞争。本文的分析表明,审计市场的市场占有率变动率更为合理地衡量市场的动态变化,审计市场的进入壁垒主要是准入壁垒(管制壁垒),而结构性壁垒和流动性壁垒主要存在于大客户市场,对于小客户市场的影响作用很小。为了防止进入者的进入,在位者通过各种流动性壁垒的设置以提高进入者的成本。但从总体看,审计市场仍然是高度竞争的。     

Incomplete regulation, market competition and collusion

Regulators often do not regulate all firms competing in a given sector. Due to product substitutability, unregulated competitors have incentives to bribe regulated firms to have them overstate their costs and produce less, thereby softening competition. The best collusion-proof contract entails distortions both for inefficient and efficient regulated firms (distortion ‘at the top’). But a contract inducing active collusion may do better by allowing the regulator to ‘team up’ with the regulated firm to indirectly tax its competitor. The best such contract is characterized. It is such that the unregulated firm pays the regulated one to have it truthfully reveals its inefficiency. We finally compare those contracts.     

Hierarchies in organisations and labour market competition

This paper studies the endogenous determination of hierarchies in firms. Firms can design a hierarchy with a continuum of ranks, one for each ability level. Nevertheless, in the market equilibrium, they choose to have only a finite number of ranks, so that in each rank there are workers of different abilities, who produce different output, and receive the same wage. It is also shown that an increase in the extent of labour market competition reduces the number of ranks in the hierarchy.     

The relationship between product market competition and unemployment with profit sharing

We investigate the implications of product market imperfections on negotiated wages and equilibrium unemployment under profit sharing. We show that intensified product market competition reduces equilibrium unemployment in a strictly monotonic way when the trade union's bargaining power exceeds the profit share. If the profit share exceeds the trade union's bargaining power, the effect of product market competition is ambiguous: there is a threshold for the benefit–replacement ratio above (below) which intensified product market competition increases (decreases) equilibrium unemployment. The profit share and the union's bargaining power affect the wage mark-up, and thereby equilibrium unemployment, in different directions.     

Intermodal competition in the London-Paris passenger market: High-Speed Rail and air transport

This paper studies inter- and intramodal competition in the London-Paris passenger market during the period 2003-2009. We identify the degree to and conditions under which High-Speed Rail is a viable substitute for airline travel. Using pooled cross-sectional data we estimate multinomial and mixed logit models to examine actual travel behaviour. Our model allows us to analyse the reaction of passenger behaviour on the withdrawal of aviation alternatives and the completion of the High-Speed Rail link between the two cities in November 2007. The results show that travel time and frequency are the main determinants of travel behaviour. The valuation of total travel times changes over the years following the opening of the High-Speed Rail link. Furthermore, we show that the direct elasticity of market share with respect to frequency for a number of aviation alternatives is above 1, indicating that these alternatives are not able to maximise profits. These alternatives subsequently left the market in our sample period. For the remaining aviation alternatives, except for easyJet, we find elasticities of market share with respect to frequency close to 1. Therefore, we conjecture that competition in this market will decline in the long run.     

The greening of industry: needs of the field

This article takes stock of some of the advances research on the greening of industry has made over the last decade and sets out an agenda for the next one. Obviously, a thorough review of all of the work on the greening of industry is outside the scope of this article. Instead we will only outline the evolution of the field and focus on the area of inquiry situated at the centre of greening of industry studies: the determinants and consequences of greening. These two questions were the focus of some of the first greening of industry studies and a multitude of works, especially on the determinants of greening, subsequently has identified numerous important insights. Yet, this area of inquiry also exemplifies major weaknesses within research in data on the greening of industry. Progress in our understanding of greening has been hampered by a lack of theoretical and methodological rigour. This article points out the resulting gaps in the scientific analysis of greening and lays out research necessary to improve our understanding of its causes and consequences. © 1998 John Wiley & Sons, Ltd and ERP Environment.     

Effect of Certificate of Need Law on the intensity of competition: The market for emergency care

PurposeThis article aims to contribute to the academic literature in better understanding the impact of Certificate of Need (CON) Law on Emergency Department (ED) care. Impact of CON Law on ED competition remains an unanswered empirical question.MethodsWe examine the impact of CON Law and its stringency on the intensity of competition (rivalry among competitors) between EDs measured by the Herfindahl-Hirschman Index (HHI). We then estimate the effects of CON Law on HHI by treating CON as an exogenous (endogenous) variable.FindingsOn average the CON legislation enhances ED competition. A possible reason is that the law hinders predatory behavior, and therefore acts as an effective anti-trust tool. Other findings indicate that competition is found to be positively related to a state's population size and median income and negatively related with the prevalence of employer provided insurance and magnitude of illegal immigration in a state.Practical implicationsThis article sheds some light on how political regulations could affect healthcare market and hence may provide public policy makers some insights on reducing healthcare cost.OriginalityOur analysis of the impact of CON regulation on ED competition significantly contributes to the healthcare and strategy literature. The law potentially serves as an anti-trust tool in the hands of the government. We extend the empirical literature by treating CON Law and its stringency as exogenous (endogenous). Our comprehensive analysis considers a host of control variables such as population demographics, their health status and access to health care, healthcare facilities, political environment, in addition to the CON features.     

Imitation and price competition in a differentiated market

We study the stable market outcome that evolves in a spatially differentiated market when price-competing firms choose actions by imitation of the most profitable firm. We compare and contrast the stable outcomes under two imitation procedures: one, where each firm immediately imitates the most profitable firm, and the other when a firm imitates another firm only if it is more profitable while being “sufficiently similar” (in context of the market segment it operates in) or “sufficiently close”. In either case, the symmetric pure strategy Nash equilibrium is always a stable outcome. However, when imitation of the most profitable firm is immediate and market differentiation is ‘moderate’, states with prices lower than the Nash equilibrium are also stable. In contrast, when imitation of the most profitable firm is more gradual and market differentiation is below a threshold, states with prices above the Nash equilibrium are also stable. Thus, while competitive evolutionary pressure in this imitation based model does result in the Nash equilibrium always being stable, other outcomes may be stable as well. Interestingly, the states that are stable under gradual imitation give the firms a higher profit than the stable states under immediate imitation.

Spatial price competition in the Manhattan hotel market: The role of location,quality, and online reputation

We investigate whether and to what extent price competition among hotels in Manhattan is driven by geographic location, quality, and online reputation. We investigate (a) which of the three product differentiation dimensions matters most for hotels' pricing decisions and (b) whether and to what extent competition is localized. Results show that hotel quality and geographic location matter the most for price competition. Whereas hotels of similar reputation also react to each other's prices, the effect is less important. Also, results indicate that hotels' prices react most aggressively to prices set by the four nearest hotels in the area.     

Acquisitions in the biopharmaceutical IPO market: Collaboration,competition and co‐opetition

The present paper explores the little studied area concerning the acquisition of recent biopharmaceutical initial public offering firms. We examine the nature of the relationship between the acquiring firm and the acquired initial public offering firm prior to the acquisition and from the perspective of the resource‐based view. We find to some extent that firm specific‐resources affect the prospect that the firm will be acquired. Furthermore, our findings show that firms with more of these types of resources are likely to be acquired by firms engaged in co‐opetition rather than by firms engaged solely in collaboration, competition, or (to a limited extent) with no prior relationship.     

Capital structure,product market competition and firm performance: Evidence from South Africa

This paper investigates the relationship between capital structure and firm performance, paying particular attention to the degree of industry competition. The paper applies a novel measure of competition, the Boone indicator, to the leverage-performance relationship. Using panel data consisting of 257 South African firms over the period 1998–2009, this paper examines the effect of capital structure on firm performance and investigates the extent to which the relationship depends on the level of product market competition. The results suggest that financial leverage has a positive and significant effect on firm performance. It is also found that product market competition enhances the performance effect of leverage. The results are robust to alternative measures of competition and leverage.

Regulation in the market for education and optimal choice of curriculum

We analyze educational institutions’ incentives to set up demanding or lax curricula in duopolistic markets for education with endogenous enrolment of students. We assume that there is a positive externality from student achievement to the local economy. Comparing the case of regulated tuition fees with an unregulated market, we identify the following inefficiencies: Under regulated tuition fees schools will set up inefficiently lax curricula in an attempt to please low-quality students even if schools internalize some of the externality. On the other hand, unregulated schools set up excessively differentiated curricula in order to relax competition in tuition fees. Deregulation gets more attractive if a larger fraction of the externality is internalized.
