On Hotelling's competition with non-uniform customer distributions

Hotelling's competition in a two-stage (location, price) game is examined with increasing densities of consumers towards the centre. It is shown that there is a range of, rather even, distributions for which firms locate at opposite ends of the market. As the distribution becomes more concentrated, duopolists will tend to move inside the market.     

Minimum safety standard,consumers’ information and competition

This paper explores the effects of a standard influencing care choice with an endogenous market structure. Under duopoly, firms compete either in prices or in quantities. Firm(s) may increase the probability of offering safe products by incurring a cost. A standard may correct a safety underinvestment by firms. It is shown that the market structure (duopoly or monopoly) linked to the standard depends on the available information. Under perfect information about safety for consumers, the selected standard is always compatible with competition. The absence of standard due to safety overinvestment by firms only emerges under competition in quantities and a relatively low cost of safety improvement. Under imperfect information about safety for consumers, the selected standard often leads to a monopoly situation, essential for covering the cost of safety improvement. However, for relatively high values of this cost, a standard cannot impede the market failure arising from the lack of information.      

Spatial competition with intermediated matching

This paper studies a two-sided market where the one type of agents needs the service of a middleman or matchmaker in order to be matched with the other type. The matchmakers compete for agents of both types by means of commission fees. In addition to the fee, the agents also lose a certain transaction cost in case of a match, which may differ among agents. Furthermore, agents have a limited willingness to pay for the service provided by the matchmakers. In certain cases the matchmakers are willing to subsidize one side of the market. Then one of the types of agents is free-riding.     

Price distributions and competition

This paper utilizes an equilibrium search model to investigate market structure and price dispersion. In a market with one large firm and a competitive fringe, the large firm offers the highest price. Fringe firms offer a distribution of lower prices.     

Hotelling's competition with general customer distributions

Hotelling and his critics assumed uniformly distributed demand. In this note the solution is characterized for any distribution F and some propositions follow. For any F an equilibrium does not exist if the duopolists are located too closely together, but another distribution can be always found for which an equilibrium does exist. When we observe duopolies in equilibrium with closer and closer proximity we can expect the density in the area of contention to go up and prices and profits to go down. Hotelling's known suggestion that any duopolist has an advantage to move his location towards the other, and thus creating a tendency for the differentiation to diminish, holds whenever an equilibrium exists.

Strategic delegation in asymmetric tax competition

This study examines asymmetric tax competition under representative democracy systems. The findings show that the degree of asymmetry between countries affects the result of elections in each country, where the citizens select a policy‐maker to set a tax rate for the country. In particular, under certain conditions, a decisive voter in the election can select a citizen whose share of the country's capital is higher than the decisive voter's own share.     

Standards vs. labels with imperfect competition and asymmetric information

I demonstrate that providing information about product quality is not necessarily the best way to address asymmetric information problems when markets are imperfectly competitive. In a vertical differentiation model I show that a Minimum Quality Standard, which retains asymmetric information, generates more welfare than a label, which provides full information.     

Spatial dispersion in cournot competition

This paper considers the spatial model used by Anderson and Neven (1991) to study firms' decisions on locations without restricting the consumers' reservation price. We note that the pattern of locations varies as the reservation price for a fixed transportation rate decreases. For a high enough reservation price, we find Anderson and Neven (1991)'s result where firms group at the center of the market and serve all consumers. As the reservation price falls, firms start to move away from each other, increasing the quantities shipped to the consumers close to their locations.     

Spatial monopolistic competition versus spatial monopoly

This paper compares the equilibrium firm output, market area, price of services, and level of net benefits in monopolistically competitive spatial equilibrium versus the multiplant monopolists spatial equilibrium. Through a computer simulation, it is found that the welfare comparisons depend on population density—the monopolists equilibrium is superior to the monopolistically competitive equilibrium in high density areas and vice versa, contrary to traditional economic theory in which distance is assumed costless.     

Implementing partial tax harmonization in an asymmetric tax competition game with repeated interaction

This paper investigates the conditions under which partial harmonization for capital taxation is sustained in a repeated interactions model of tax competition when there are three countries with heterogenous capital endowments. We show that regardless of the structure of the coalition (i.e., full or partial tax coordination), whether partial tax harmonization is sustainable or not crucially depends on the extent to which the capital endowment of the medium‐sized country is similar to that of the large or small country. The most noteworthy finding is that the closer the capital endowment of the median country is to the average one, the less likely the tax harmonization including the median country is to prevail and the more likely the partial tax harmonization excluding the median country is to prevail. We also show that partial tax harmonization makes the member countries of the tax union better off and non‐member countries worse off, which stands in sharpe contrast with previous studies, such as Konrad and Schjelderup (1999) and Bucovetsky (2009).     

Policy competition for foreign direct investment between asymmetric countries

The present paper analyses policy competition for foreign direct investment between countries of different size and different market structure. We demonstrate how policy competition affects the location decision of the foreign investor and derive welfare implications. The key variables in our analysis are intra-regional trade costs, differences in market size, and minimum wages.     

Welfare effects of competition for FDI between technologically asymmetric countries with varying trade costs

Given the traditional argument that host countries' excessive competition for FDI (foreign direct investment) deteriorates the host countries' welfare, this paper examines the impact of policy competition for FDI on social welfare considering varying trade costs. Based on a model where two technologically asymmetric countries compete for FDI, we determine an equilibrium where a multinational firm relocates to a less efficient country. Moreover, we demonstrate that the policy competition for FDI between less integrated economies might improve social welfare when the multinational firm relocates to a country with a lower technology and a less competitive market. Nonetheless, we show that the traditional argument can be true when the policy competition for FDI between highly integrated economies deteriorates host countries' welfare, as supported by the empirical evidences of moderated competition for FDI within EU member countries.     

Endogenous timing in tax competition: The effect of asymmetric information

This study explores the effects of asymmetric information on endogenous leadership in a simple tax competition environment. The study models a two-country economy where one country is informed about its own and opponent's productivity of private goods, while the other country only knows its productivity. The results show that each type of informed country has an incentive to pretend to be the other type, which leads to a Stackelberg outcome endogenously, while the simultaneous move is the unique outcome under complete information. Under the Stackelberg outcome, the uninformed country moves first and the informed country moves second. Moreover, ex-post social welfare under asymmetric information can become larger than that under complete information, because the uninformed country chooses a less aggressive tax rate under asymmetric information. These results depend on the type of uncertainty, and capital ownership and share.     

Spatial Cournot competition in a circular city with more than two dispatches

This paper investigates spatial Cournot competition in a circular city, where the maximal service range of a vehicle is less than half of the perimeter, and a firm needs to initiate more than two dispatches to serve the whole market. We examine a multi‐stage game of location and transportation mode choices, and the subsequent quantity competition between duopoly firms. The findings reveal that non‐maximum dispersion is the unique location equilibrium when duopoly firms deliver products in different transportation modes or when the transportation mode decisions are made endogenously and the fixed cost of a transportation instrument is relatively high.     

Interconnection and competition among asymmetric networks in the Internet backbone market

We examine the interrelation between interconnection and competition in the Internet backbone market. Networks that are asymmetric in size choose among different interconnection regimes and compete for end-users. We show that a direct interconnection regime, peering, softens competition as compared to indirect interconnection since asymmetries become less influential when networks peer. If interconnection fees are paid, the smaller network pays the larger one. Sufficiently symmetric networks enter a Peering agreement while others use an intermediary network for exchanging traffic. This is in line with considerations of a non-US policy maker. In contrast, US policy makers prefer that relatively asymmetric networks peer.     

Sequential equilibria of asymmetric ascending auctions: The case of log-normal distributions

Summary. The sequential equilibrium of an ascending-price auction of a single item is derived explicitly for the case of log-normal distributions and a multiplicative valuation model comprising both common and private factors, and allowing asymmetries. If the prior distribution on the common factors is diffuse, or of the form obtained by Bayesian updating from a diffuse prior distribution, then the equilibrium strategies are log-linear with coefficients obtained by solving a set of linear equations. A similar construction applies to normal distributions and additive terms in the valuation model. An example illustrates the predictions derived from the model.

Perfect competition in asymmetric information economies: compatibility of efficiency and incentives

The idea of perfect competition for an economy with asymmetric information is formalized via an idiosyncratic signal process in which the private signals of almost every individual agent can influence only a negligible group of agents, and the individual agents’ relevant signals are essentially pairwise independent conditioned on the true states of nature. Thus, there is no incentive for an individual agent to manipulate her private information. The existence of incentive compatible, ex post Walrasian allocations is shown for such a perfectly competitive asymmetric information economy with or without “common values”. Consequently, the conflict between incentive compatibility and Pareto efficiency is resolved exactly, and its asymptotic version is derived for a sequence of large, but finite private information economies.     

Learning in asymmetric duopoly markets: competition in information and market correlation

This paper explores experimentation and learning in asymmetric duopoly markets with product differentiation and demand uncertainty. We define the concepts of strategic substitutability and strategic complementarity in information and we show how both the mode of information competition and the transmission of information across markets affect duopoly experimentation. We relate information competition with market competition and we find that, when goods are substitutes and the correlation between market shocks is negative, firms will have a higher incentive to experiment in asymmetric markets than in symmetric ones. The opposite result follows when such correlation is positive. Also, when goods are complements the above findings are reversed.JEL Classification: D83, C72The authors thank partial financial support from the Spanish Ministry of Science and Technology under project B2000-1429, from the Spanish Ministry of Education and Science under project SEJ2004-07554 and from the “Generalitat Valénciana” under project GRUPOS04/13.
