We consider a simple multi‐period model where the entry cost varies with respect to the number of firms that have entered previously. In the non‐cooperative outcome, there is clustered entry among the firms in the last period; hence, the full potential of learning is not expropriated. When firms are allowed to form coalitions, the non‐cooperative outcome is dominated; thus, there is a gain in efficiency. We also find that full efficiency is obtained when a grand coalition is formed. The implications of policies on coalitions as well as on individual firms are also discussed. 相似文献

This paper provides an economic analysis on the choice of backward compatibility by a durable goods monopolist in the presence of network effects. We examine the time inconsistency problem faced by a monopolist in its dynamic provision of two compatible products. We suggest an economic reason why, and when it will be strategically optimal, for the monopolist to choose backward compatibility even though it is socially undesirable, and not to choose forward compatibility even though it is technologically possible. We also investigate the compatibility choices with and without price discrimination, and compare market outcomes with the social optimum. Two different social inefficiencies (planned obsolescence) which arise from the viewpoints of optimal consumption and optimal compatibility are discussed. 相似文献

We show that if agents are risk‐neutral, prizes outperform wages if and only if there is sufficient pride and envy relative to the noisiness of performance. If agents are risk‐averse, prizes are a necessary supplement to wages (as bonuses). 相似文献

We investigate the endogenous choice of roles by managerial firms in the presence of unilateral externality. The choice over timing can be taken either by managers or by owners. It is shown that: (i) the choice of the timing by managers entails the same profit that owners would have achieved by specifying the timing in the delegation contract; and (ii) firms move simultaneously if the degree of unilateral externality is small, while sequentially if the degree of unilateral externality is large, with the firm generating unilateral externality as a follower; the owner of the follower firm delegates to restrict output, while his/her counterpart does not delegate it. 相似文献

This paper investigates finitely repeated prisoners' dilemma games with explicit contractual devices. It shows that full collusion can be achieved in a unique manner by incentivizing the players' final‐period play with small fines. The incentivizing modality is the penance contract, by which a player is penalized if and only if he deviates from the penance strategy in the final period. Using this contractual agreement brings the penance strategy profile into unique subgame perfect equilibrium in the entire game and achieves full collusion without being invalidated by renegotiation. 相似文献

Concerning industrial location, the home market effect (HME) predicts that a large country is a net exporter of industrial goods. Recent literature shows that high transport costs in the traditional sector may obscure the HME in an early model of two sectors à la Helpman and Krugman. This paper presents an alternative model that displays the relationship between the HME and arbitrary transport costs while allowing for the derivation of analytical results by simple algebra. Our results show that the transport costs in the traditional sector do not obscure the HME but constitute a dispersion force that decreases the impact of the HME. 相似文献

We analyse the implications of quality differences in a vertically differentiated product market for social welfare by employing an endogenous quality choice model. We find that in of Bertrand and Cournot duopolies, the degree of quality differentiation at equilibrium in an unregulated market is larger or smaller, respectively, than that of the socially second‐best optimum. This implies that a reduction in quality difference, respectively, increases or decreases social welfare in the case of Bertrand or Cournot duopolies. 相似文献

In this paper, we explore whether heterogeneity among union members could threaten the stability of the European Monetary Union. The types of heterogeneity we consider are (1) asymmetries in the transmission of monetary and fiscal policies, and (2) differences in national preferences for price stability, output growth, and income redistribution. Our results show that the costs of membership can be significant for countries whose transmissions, structure, or preferences deviate from those underlying the common monetary policy. In part, these costs arise because monetary policy imposed by an independent central bank automatically constrains the use of fiscal policy by national governments. 相似文献

To sustain constant consumption, Hartwick's rule prescribes reinvesting all resource rents in reproducible capital. However, Hartwick's rule is not necessarily the result of optimization. In this paper, we address this insufficiency by deriving a constant consumption path endogenously in a semi‐open economy with an exhaustible resource, which has full access to world goods and capital markets, while the resource flows are not internationally tradable. Our findings show that, due to the essentiality of both capital and resource to the production process, the economy transforms its domestic assets into foreign ones, consuming a constant interest flow from the latter. 相似文献

The existence of a pure‐strategy subgame‐perfect equilibrium in qualities and prices is investigated in a duopoly model of vertical differentiation where quality improvements require a quadratic variable cost and network externalities operate. We show that there exists a parameter region where the incentive to predate at the quality stage prevents firms from reaching a pure‐strategy non‐cooperative equilibrium with prices above marginal costs. If network externalities are sufficiently large, a Bertrand equilibrium with zero profits may arise, although the amount of product differentiation is strictly positive. 相似文献

This paper provides an econometric analysis of a duopoly game in the Japanese domestic airline market. We establish a novel Bayesian estimation approach for the entry game, which allows the incorporation of flexible inference techniques. We find asymmetric strategic interactions between Japanese firms. This result implies that competition is still influenced by the former regulation regime. Furthermore, our prediction analysis indicates that the new Shizuoka airport will suffer from a lack of demand in the future. 相似文献

We present a model of incomplete information games, where each player is endowed with a set of priors. Upon arrival of private information, it is assumed that each player “updates” his set of priors to a set of posterior beliefs, and then evaluates his actions by the most pessimistic posterior beliefs. So each player's preferences may exhibit aversion to ambiguity or uncertainty. We define a couple of equilibrium concepts, establish existence results for them, and demonstrate by examples how players’ views on uncertainty about the environment affect the strategic outcomes. 相似文献

We develop dual approaches to quantity and price relationships of production in a general multisectoral model with sector‐specific externalities. The production of each good exhibits socially constant returns to scale but privately decreasing returns. We find that the Stolper‐Samuelson theorem holds for factor intensity ranking from the social perspective and that the Rybczynski theorem holds for factor intensity ranking from the private perspective. The price‐output dual fails to hold in general. Moreover, we re‐establish the Heckscher‐Ohlin theorem in the two‐sector case, as well as the factor endowment–factor price and price‐output comparative statics in the high‐dimension case under proper conditions. 相似文献

We study experimental two-sided markets in which the information structure is endogenous. When submitting an offer, a trader decides which other traders will be informed about the offer. This setup allows both a decentralized bargaining market (Chamberlin, J. Polit. Econ. 56 (1948) 95), and a double auction market (Smith J. Polit. Econ. 70 (1962) 111) as special cases. The results show that offers are typically directed to all traders of the other side of the market, but to none of the traders of the same side of the market. Even though traders receive much less information, the resulting market institution leads to the same outcomes in terms of prices and efficiency as a double auction market. In two additional treatments we examine the robustness of these results. First, it is found that the market institution adapts predictably, but not necessarily efficiently, to the imposition of transaction costs. Second, we find that the preference of sellers to conceal offers from competitors is strict. At the same time, sellers benefit collectively when they reveal offers to each other. 相似文献

A REVISIT OF INTERNATIONAL STOCK MARKET LINKAGES: NEW EVIDENCE FROM RANK TESTS FOR NONLINEAR COINTEGRATION 总被引:1,自引:0,他引:1

Based on a theory proposed for the possible link between financial market integration and nonlinear cointegration, this study reinvestigates international stock market linkages by performing both conventional linear cointegration tests and newly developed rank tests for nonlinear cointegration. The stock price indexes of Australia, Japan, New Zealand, the United Kingdom and the United States are used, with daily data spanning from 29 May 1992 to 10 April 2001. Much more evidence of market integration emerges from nonlinear than linear cointegration analysis, suggesting that comovements among various national stock markets may well take nonlinear forms. Our findings challenge the conclusion of market segmentation reached in some previous studies that only conducted linear cointegration analysis. 相似文献

This note re‐examines the previous results on durable goods monopolists under the time inconsistency problem that the firm tends to make its goods less compatible as a “planned obsolescence” strategy in the presence of network effects. We find that the possibility of the commitment to forward compatibility is profitable to the monopolist, depending upon the degree of technological progress and network effects. Therefore, contractual commitments that are frequently feasible and observed in real‐world markets make the society better off. 相似文献

We present results on undiscounted optimal policies in the Leontief two‐sector growth model with durable capital. Unlike the results with a labour intensive consumption goods sector, we show that a monotonic optimal programme is only one special case out of many richer possibilities of transition dynamics. Depending on the initial capital stock, and a key parameter ζ that could be interpreted as a marginal rate of transformation of capital between today and tomorrow, an optimal programme may converge to a period‐two cycle; and even when it converges to the golden rule stock, it can do so (damped) cyclically or with a “jump”. 相似文献

We study an alternating offers bargaining model in which the set of possible utility pairs evolves through time in a non-stationary, but smooth manner. In general, there exists a multiplicity of subgame perfect equilibria. However, we show that in the limit as the time interval between two consecutive offers becomes arbitrarily small, there exists a unique subgame perfect equilibrium. Furthermore, we derive a powerful characterization of the unique (limiting) subgame perfect equilibrium payoffs. We then explore the circumstances under which Nash's bargaining solution implements this bargaining equilibrium. Finally, we extend our results to the case when the players have time-varying inside options. 相似文献
