Mergers in Emerging Markets with Network Externalities: The Case of Telecoms
This paper develops a unifying framework to understand competition issues in networkindustries. It focuses on the telecom(munication) industry and takes two specific effectsof this industry into account. First, the telecom industry is in continuous evolution andalliances affect not only the current market power of the firms but also the evolution ofthe industry. Second, the production of services in the industry is evolving towards theprovision of integrated services in a "system" that benefits from strong "networkexternalities". The analysis suggests that the antitrust authorities should capture as wellsuch effects as the magnitude of the installed bases, the compatibility of the allianceâssystem with other systems, the switching costs for customers and application writers,and the "credibility" of the alliance to offer the service. The developed frameworkbuilds on the existing models of networks and combines the different network effects. The relevance of the framework is shown for two important merger cases (WorldCom-MCI and MSG cases), involving respectively an existing market and an emerging one. ZUSAMMENFASSUNG - (UnternehmenszusammenschlĂŒsse in entstehenden MĂ€rkten mit NetzexternalitĂ€ten: Das Beispiel der Telekommunikationsindustrie) In diesem Beitrag wird ein einheitlicher Bezugsrahmen zur Analyse des Wettbewerbs in Netzwerkindustrien entwickelt. Er zielt auf die Analyse der Telekommunikationsindustrie ab und berĂŒcksichtigt dabei spezielle Effekte dieser Industrie. Erstens ist die Telekommunikationsindustrie durch eine stetige Evolution gekennzeichnet und Allianzen zwischen den Unternehmen beeinflussen nicht nur die aktuelle Marktmacht der Unternehmen, sondern auch die Entwicklung der Industrie. Zweitens entwickelt sich die Produktion der Dienste in dieser Industrie immer stĂ€rker in Richtung auf das Angebot integrierter Dienste (Systemangebote), die Vorteile aus NetzexternalitĂ€ten nutzen. Die Analyse zeigt auch, daĂ die Wettbewerbsbehörden ebenfalls Merkmale wie die Anzahl der verfĂŒgbaren AnschlĂŒsse, die KompatibilitĂ€t des Systems der Allianz mit anderen Systemen, die Wechselkosten der Kunden sowie die GlaubwĂŒrdigkeit der DienstleistungsqualitĂ€t der Allianz berĂŒcksichtigen sollten. Der entwickelte Bezugsrahmen stĂŒtzt sich auf die vorhandenen Netzmodelle und kombiniert die unterschiedlichen Netzeffekte und -merkmale. Die Bedeutung des Ansatzes wird am Beispiel von zwei wichtigen FusionsfĂ€llen aufgezeigt (WorldCom-MCI und MSG), bei denen es sich jeweils um einen existierenden und einen entstehenden Markt handelt.
Competing for Ownership
We develop a tractable model of the allocation of ownership and control in firms in competitive markets that permits study of how the scarcity of assets in the market translates into control allocations inside the organization. The model identifies a price-like mechanism whereby local liquidity or productivity shocks propagate and lead to widespread organizational restructuring. Firms will be more integrated when the terms of trade are more favorable to the short side of the market, when liquidity is unequally distributed among existing firms and following a uniform increase in productivity. Shocks to the first two moments of the liquidity distribution have multiplier effects on the corresponding moments of the distribution of ownership.
Managerial Firms, Vertical Integration, and Consumer Welfare
We show that vertical integration decisions of managers may affect adversely consumers even in the absence of monopoly power in either supply or product markets. This effect is most likely to come about when demand is initially high and there is a negative supply shock or when demand is low and there is a positive demand shock. The results are robust to the introduction of active shareholders and to other extensions.
Competitive Prices and Organizational Choices
We construct a price-theoretic model of integration decisions and show that these choices may adversely affect consumers, even in the absence of monopoly power in supply and product markets. Integration is costly to implement but is effective at coordinating production decisions. The price of output helps to determine the organizational form chosen: there is an inverted-U relation between the degree of integration and product prices. Moreover, organizational choices affect output: integration is more productive than non-integration at low prices, and less productive at high prices. Since shocks to industries affect product prices, reorganizations are likely to take place in coordinated fashion and be industry specific, consistent with the evidence. Since the price range in which integration maximizes productivity generally differs from the one in which it maximizes managerial welfare, organizational choices will often be second-best inefficient. We show that there are instances in which entry of low-cost suppliers can hurt consumers by changing the terms of trade in the supplier market, thereby inducing reorganizations that raise prices.
How to Win Twice at an Auction. On the Incidence of Commissions in Auction Markets
We analyze the welfare consequences of an increase in the commissions charged by the organizer of an auction. Commissions are similar to taxes imposed on buyers and sellers and the economic problem that results looks similar to the question of tax incidence in consumer economics. We argue, however, that auction markets deserve a separate treatment. Indeed we show that an increase in commissions makes sellers worse off, but some (or all) buyers may gain. The results are therefore strikingly different from the standard result that all consumers lose after a tax or a commission increase. We apply our results to comment on the class action against Christieâs and Sothebyâs and argue that the method used to distribute compensations was misguided.Auction, Intermediation, Commissions, Welfare
Rock and roll bands, (in)complete contracts and creativity
Members of a rock and roll band are endowed with different creativity. They match and eventually obtain credit for song writing as well as a share of the returns from sales. More creative members increase the probability of success but may also claim a larger share of the pie. In our theoretical model, the nature of matching (postive or negative assortative) as well as the covariation between the probability of having a âhitâ and the dispersion of credits given to individual members are a function of the completeness of contracting. When members adopt a âgentlemanâs agreementâ to share credits equally, the covariation between the probability of a hit and the dispersion of credits is negative, which is the consequence of positive assortative matching in creativity. The data show that the relation between dispersion and success is significantly negative, and that rock bands are thus likely to sign incomplete contracts.overlapping generations, resource management, common pool resource, spatial interdependence, strategic behaviour, cooperative behaviour
Moral Hazard and Capital Structure Dynamics
We base a contracting theory for a start-up firm on an agency model with observable but nonverifiable effort, and renegotiable contracts. Two essential restrictions on simple contracts are imposed: the entrepreneur must be given limited liability, and the investorâs earnings must not decrease in the realized profit of the firm. All message game contracts with pure strategy equilibria (and no third parties) are considered. Within this class of contracts/equilibria, and regardless of who has the renegotiating bargaining power, debt and convertible debt maximize the entrepreneurâs incentives to exert effort. These contracts are optimal if the entrepreneur has the bargaining power in renegotiation. If the investor has the bargaining power, the same is true unless debt induces excessive effort. In the latter case, a non-debt simple contract achieves efficiency â the non-contractibility of effort does not lower welfare. Thus, when the non-contractibility of effort matters, our results mirror typical capital structure dynamics: an early use of debt claims, followed by a switch to equity-like claims.Moral hazard, renegotiation, convertible debt, capital structure
Trade Liberalization and Organizational Choice
We embed a simple incomplete-contracts model of organization design in a standard two-country, perfectly-competitive trade model to examine how the liberalization of product and factor markets affects the ownership structure of firms. In our model, managers decide whether or not to integrate their firms, trading off the pecuniary benefits of coordinating production decisions with the private benefits of operating in their preferred ways. The price of output is a crucial determinant of this choice, since it affects the size of the pecuniary benefits. In particular, non-integration is chosen at "low" and "high" prices, while integration occurs only at moderate prices. Organizational choices also depend on the terms of trade in supplier markets, which affect the division of surplus between managers. We obtain three main results. First, joint product and factor market integration leads to the convergence of organization design across countries. Second, even in the absence of factor movements, the price changes triggered by liberalization of product markets can lead to significant organizational restructuring within countries. Third, the removal of barriers to factor mobility can induce further organizational changes, sometimes adversely affecting consumers, which suggests a potential complementarity between trade policy and corporate governance policy.

Third, âdeep integrationâ the liberalization of both product and factor markets  leads to the convergence of organizational design across countries.Firms, Contracts, Globalization
