This paper examines the relationship between firms’ productivity improvement and the volume of exports, and shows that it can be sometimes negative, which seems to be an empirical puzzle. The key lies in that we simultaneously take into account intermediate retailers (i.e. vertically) and multimarket linkages (i.e. horizontally). With convex cost functions, when market conditions worsen, the manufacturer increases supply to the retailer who is larger or more efficient in trade cost. 相似文献

We investigate the relationship between the degree of competition and the stability of collusive behaviour, by introducing the element of relative performance in the objective functions of the firms. We show that an increase in the degree of competition destabilizes the collusion. This relation differs starkly in the standard symmetric Cournot and Bertrand duopoly models, with the former being more unstable than the latter. 相似文献

We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) [20] that restricts the message spaces. The principal does not require any incentive wage schemes and can therefore avoid any information rent and welfare loss. We show the resemblance between the functioning of this message space restriction and that of incentive wage schemes. We also extend the results of the single-agent model to the multi-agent model. 相似文献

In this paper, we analyze the strategic residential location choices of multiple siblings who receive childcare assistance from their parents. Our three stage game yields a theoretical result that first-born children are more likely to live together with or close to their parents than second-born children, which is supported by our estimation results using Japanese micro-data. We also empirically show that the childcare assistance from parents is one of the determinants of the residential location choice of siblings. This paper is the first to succeed in explaining the residential location choice of siblings in Japan using economic incentives. 相似文献

The valuation of intangible assets, such as patents, has recently been considered an important technique for R&D strategies. This paper proposes a citation analysis as a method of valuation on patent clusters having patent networks. A citation analysis is a method that examines the value of a patent on the basis of the number of citations of references. In particular, a co-citation analysis is used for coupling patents as the patent cluster and valuating the patent cluster. While the co-citation analysis is of great interest as a method of valuation, this analysis has not been fully examined and does not define any framework for a technology transition and patent strategy. Therefore, in this paper, the conventional co-citation analysis for evaluating the patent clusters is enhanced and frameworks for the technology transition and patent strategy are proposed by analysing citation routes in a co-citation analysis. 相似文献

We investigate competition between a domestic intellectual property right holder and a foreign imitator and consider how parallel
imports affect their profits. We consider a two-country model. Country A is a developed country where intellectual property
rights are highly protected, and country B is a developing country where protection is weak. The intellectual property right
holder can sell the products for both markets while the imitator cannot export the products to country A. We find that permitting
parallel imports can be beneficial for both players because it serves as a commitment device to soften price competition. 相似文献

Consider an oligopolistic industry where production is time-consuming, so that each firm needs to make quantity commitment by producing before the market opens. If demand uncertainty resolves some time before the market arrives, then those firms who produce early behave as simultaneous leaders (co-leaders), whilst those who wait until demand becomes observable will be followers. We discover that, in an n -firm oligopoly, the equilibrium number of co-leaders tends to be in excess of their socially optimal number, albeit both numbers monotonically decrease in the magnitude of demand uncertainty relative to the expected level of demand. We also find that, with demand uncertainty and the possibility of Stackelberg behaviour, whether the excess entry theorem applies depends upon the number of existing followers. 相似文献

We investigate the sequential choice of location in a mixed duopoly, where a welfare–maximising public firm competes against a profit–maximising private firm. We examine the desirable role of the public firm in a mixed market. We also consider the effect of price regulation. We find that the public firm should become the follower (leader) if a price regulation is (is not) imposed. We also find that neither price regulation nor privatisation of the public firm improves welfare. 相似文献

This study examines how the demand and supply of healthcare services have responded to the expansion of health insurance coverage in Vietnam by using biyearly provincial panel data from 2006 to 2014. The results of our analysis indicate significant progress towards universal health coverage (UHC) in Vietnam, with the expansion of health insurance coverage being accompanied by increases in admissions and inpatient days. However, some concerns remain. Our findings show a positive response of supply capacity only in terms of doctors and nurses at higher‐level hospitals (provincial hospitals), and none in other relevant aspects. Moreover, we find no positive response of the number of outpatient visits. Another concern is the issue of financial protection. The decline in out‐of‐pocket payments is not significant throughout our observation period, suggesting that lowering the cost of healthcare is not straightforward and that the expansion of health insurance coverage alone cannot achieve this. We believe that the Vietnamese experience has valuable implications for other emerging and developing countries, considering that the expansion of health insurance coverage is likely to increase utilization of healthcare services significantly and that the supply side needs to be prepared for the increase. 相似文献
