Negotiated tariffs in free entry oligopoly under integrated markets

Using the Nash bargaining approach, this paper analyzes the negotiation of tariffs between two countries in free-entry oligopolies under integrated markets. Employing a symmetric model with linear demand and cost functions, the paper shows that for both countries Pareto-efficient negotiated tariffs are larger than the tariffs at the Nash equilibrium of a non-cooperative tariff game (tariff war) in which each country imposes its optimum tariff.     

Does advertising mislead consumers to buy low-quality products?

This paper investigates the interaction between consumer learning and advertising using a simulation model. Consumers use advertising to estimate the quality change, but learn advertising's trustworthiness through their consumption experience. Firms spend on not only advertising but also R&D to improve its product quality, following satisficing principles. We found that, if consumer learning is slow, an advertising-intensive firm captures most of the market in the long run despite its low product quality; in this sense, advertising misleads consumers. When learning is fast or when consumers do not rely on advertising at all, advertising is unlikely to mislead them. Easy imitation of rival products also prevents advertising from being misleading. These results are consistent with existing empirical findings on advertising-quality relationships.     

Equilibrium number of firms and economic welfare in a spatial price discrimination model

We examine welfare implications of the equilibrium number of entering firms in a spatial price discrimination model. In contrast to Salop [Salop, S., 1979. Monopolistic competition with outside goods. Bell Journal of Economics 10, 141–156.], the equilibrium number of firms can be either excessive or insufficient from the normative viewpoint.     

Threshold behavior and aggregate fluctuation

This paper concerns a propagation mechanism in an economy where many individuals follow a threshold rule and interact with a positive feedback. We derive an asymptotic distribution of the propagation size when the number of the agents tends to infinity. The propagation distribution exhibits a slower convergence to a deterministic value than it would if the agents followed a smooth adjustment policy. This gives rise to significant aggregate fluctuations in a finite lumpy-adjusting economy even when the agents are hit by small independent shocks.     

Does policy reform promote FDI in developing economies? a firm-level simulation approach

How do policy reforms for foreign investors in developing economies affect inward foreign direct investment? Using a firm heterogeneity model calibrated to match data on Japanese multinational firms, we simulate how multinationals respond to a decline in investment procedure days. We find that such policy reforms in investment procedures significantly increase the aggregate entries and sales of multinational firms in developing economies, with the more pronounced impact at the extensive margin than at the intensive margin. At the firm level, declining entry costs encourage more productive firms to invest in a wider range of markets although such impacts are modest for the most productive firms that already penetrate many markets. The impacts on foreign sales per multinational firm are less clear-cut in magnitude across productivity levels in part because falling entry costs directly increase multinational entry to developing economies, but only indirectly encourage their existing production in these markets.     

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).     

Estimates of optimal public capital stocks in Japan using a public investment discount rate framework

The purpose of this paper is to empirically assess the optimality of the level of public capital in Japan. We use a methodological approach based on Burgess's (1988) procedure for calculating the public discount rate. This approach involves estimating a production function, but does not necessarily require utility function estimation. The results indicate that, although the Japanese economy experienced a public capital deficiency over the period 1960–1982, public capital moved toward optimal levels throughout the period.

作为自省之学的中国人类学——费孝通与柳田国男的学问及方法

费孝通和柳田国男分别开拓了各自对本土社会的独特研究。费孝通以“乡土”为对象,以“同情”来自省的学问,宗旨是通过对本土社会的理解来提出切实可行的对策与举措。柳田国男的“乡土研究”乃是由乡土的人们在乡土、地方或农村搜集资料,以比较之法认识乡土,最终的目的则是认识整个日本社会。从这个意义上讲,乡土研究是“自我反思”的学问,这也正是费孝通与柳田国男学术思想的共同之处。两位先生都是以解决问题为目标,采取了跨学科的知识生产方式,可以说这正好体现了近代亚洲知识分子的学问特点以及他们对于社会的责任感。     

Profitability of price and quantity strategies in a duopoly with vertical product differentiation

Using a model according to Mussa and Rosen (1978) and Bonanno and Haworth (1998) we consider a sub-game perfect equilibrium of a two-stage game in a duopolistic industry in which the products of the firms are vertically differentiated. In the industry, there are a high quality firm and a low quality firm. In the first stage of the game, the firms choose their strategic variables, price or quantity. In the second stage, they determine the levels of their strategic variables. We will show that, under an assumption about distribution of consumers' preference, we obtain the result that is similar to Singh and Vives (1984)' proposition (their Proposition 3) in the case of substitutes with nonlinear demand functions. That is, in the first stage of the game, a quantity strategy dominates a price strategy for both firms. Received: April 23, 1999; revised version: May 31, 2000     

Is a Big Entrant a Threat to Incumbents? The Role of Demand Substitutability in Competition Among the Big and the Small

We establish a model of market competition between large and small firms and investigate the way in which demand substitutability affects how the entry of big firms impacts incumbents. We focus on the relative strength of two opposing effects of entry on large incumbent firms’ demand: the direct substitution effect among large firms (negative) and the indirect feedback effect through the change in small firms’ aggregated behavior (positive). If the substitutability between large and small firms is sufficiently high, the indirect effect dominates the direct effect and large incumbents’ equilibrium prices and profits increase. We show that welfare effects are ambiguous, which calls for careful assessment when regulating large firms’ entry.
