While conjoint analysis has been applied in a wide variety of different contexts in Marketing, most applications fail to explicitly consider retaliatory reactions from competitors. In this paper, a methodological extension is developed for conjoint analysis by explicitly modeling competition in a game theoretic context. The Nash equilibrium concept is employed to model competitive reactions to produce design, and its implications for reactive product strategies are discussed. The optimal product design problem for each firm is formulated as a nonlinear integer programming problem, which is solved via a specialized branch and bound method combined with a heuristic. In order to compute a Nash equilibrium, a sequential iterative procedure is proposed. The proposed procedure is illustrated under several scenarios of competition using previously published conjoint data.This research has been supported by the Henry Rutgers Research Fellowship, Rutgers University. 相似文献

Do converters facilitate the transition to a new incompatible technology? A dynamic analysis of converters 总被引:1,自引:0,他引:1
Jay Pil Choi 《International Journal of Industrial Organization》1996,14(6):825-835
This paper analyzes the process of transition in standards between incompatible technologies when converters are available. Contrary to a common presumption that converters facilitate the transition from an old technology to an otherwise incompatible new technology, I find circumstances in which the possibility of transition is blockaded by the existence of converters. In the welfare analysis of converters, a distinction is made between ex ante and ex post efficiency effects. Finally, I also analyze the equilibrium behavior in the provision of converters and compare it to the socially optimal outcome. 相似文献

This article investigates the patterns of vertical specialization in trade among China, Japan and Korea, and the effects of real exchange rate fluctuations under a multistage production process. By extending the models of Yi (2003, 2010), we derive two distinct features of vertical specialization and test them using Time-Varying Parameter (TVP) VAR. We find that a positive shock to China’s final good consumption increases the intermediate goods trade between Korea and China, with expanding magnitude over time. In addition, the positive effect of a real exchange rate depreciation on intermediate goods trade is strengthened through the competitiveness-enhancing channel, with this effect being more pronouncing in Korea-China trade than in Korea-Japan trade. 相似文献

The 2007/2008 US financial crisis is related to the securitization of mortgage loans and the housing-price boom and bust. In this article, we test the hypothesis that housing-price change is related to the development of the financial system. Using panel data for 23 countries from 1988 to 2012, we have found that the housing-price growth rate increases as the financial system moves a bank orientation to a market orientation. The policy implication is that the government should beware sudden increases in the capital market relative to the banking sector. Especially, more sophisticated financial supervision with respect to housing-price movement is required when a bank-based financial system progresses quickly to a market-oriented financial system. 相似文献

We investigate the valuation problem of variable annuities with guaranteed lifelong/lifetime withdrawal benefit (GLWB) options, which give the policyholder the right to withdraw a specified amount as long as he or she lives, regardless of the performance of the investment. We assume the static approach that the policyholder’s withdrawal rate is a constant throughout the life of the contract. We apply the principle of equivalent utility to find the indifference price for a variable annuity with a GLWB contract with an equity-indexed death benefit. Using an exponential utility function, Hamilton-Jacobi-Bellman (HJB) type partial differential equations (PDEs) are derived for the pricing functions. We first assume the mortality is deterministic, and the pricing PDE is solved numerically using a finite difference method. The effects of various parameters are investigated, including the age at inception of the policyholder, withdrawal rate, risk-free rate, and volatility of the underlying asset. We also consider a roll-up option and analyze the effect of delaying the start of the withdrawals. Another pricing PDE is derived with a stochastic mortality, when the force of mortality is modeled with a stochastic differential equation. A finite difference method is used again to solve the pricing PDE numerically, and the sensitivities of the GLWB contracts with respect to the withdrawal rate and the risk-free rate are explored. 相似文献

We trace the extent of performance deviation of privatized banks from established private banks in 30 countries from 1994 to 2005 and investigate the role of bank regulatory and supervisory norms, market competition, ownership structure, deposit insurance scheme, and governance structure affecting the deviation. Evidence shows that privatization does improve the performance of banks in the first year of being privatized, but performance gradually declines, which is consistent with the government restructuring argument before the privatization. Governance, foreign ownership, banking freedom (regulations), and the deposit insurance scheme in respective economies are found to affect performance deviation significantly. 相似文献

The paper analyses the optimal pricing of the product quality scheme when concerns for relative standing exist among consumers. We demonstrate that if the proportion of high‐value consumers is over (respectively, under) 1/2 of the total consumers, a firm has an incentive to select a large (respectively, small) quality gap among products. Therefore, there exists a cut‐off level for status concerns, which eliminates quality differences, and the firm assigns the same quality to all the consumers. These results indicate that consumers’ qualities will reflect distortions at the top and bottom. Accordingly, the firm's profit depends on which consumer category is larger. 相似文献

Social entrepreneurship has emerged as an active area of practice and research within the last three decades. Nevertheless, in spite of its growing popularity, scholars and practitioners are far from reaching a consensus as to what social entrepreneurship actually means. This has resulted in a number of different definitions and approaches within the field of social entrepreneurship. The purpose of this article is to shed light on the ongoing contestation of social entrepreneurship and to offer a novel conceptual understanding of the concept that can facilitate the development of systematic and structured future research. To this end, we analyze social entrepreneurship on the basis of the theory of essentially contested concepts, which was proposed by Walter Bryce Gallie in 1956. Building upon this theory, this article shows that social entrepreneurship can be regarded as an essentially contested concept and that a universal definition that would be accepted among contestant parties is hardly possible. Responding to this recognition, the article proposes the conceptualization of social entrepreneurship as a cluster concept, which can serve as a conceptual tool to help advancing social entrepreneurship as a coherent field of research despite its contested nature. 相似文献
