In the present paper, we are concerned with the behavioural consequences of consumers having nontransitive preference relations. Data sets consist of finitely many observations of price vectors and consumption bundles. A preference relation rationalizes a data set provided that for every observed consumption bundle, all strictly preferred bundles are more expensive than the observed bundle. Our main result is that data sets can be rationalized by a smooth nontransitive preference relation if and only if prices can normalized such that the law of demand is satisfied. Market data sets consist of finitely many observations of price vectors, lists of individual incomes and aggregate demands. We apply our main result to characterize market data sets consistent with equilibrium behaviour of pure-exchange economies with smooth nontransitive consumers. 相似文献

三方协商机制是调整劳资关系的重要机制,并已成为许多国家的一种社会对话方式。我国调整劳资关系的三方机制建立时间短,还存在协商主体代表性不足、角色定位不准和协商范围窄等问题,需要进一步完善才能发挥三方机制应有的作用。 相似文献

We present a meta-analysis of cycle periods in historical socio-economic data found in the K-wave literature. The literature on stochastic and deterministic cycles in variables such as the consumer price index, employment, interest rates, commodity prices, GDP, war and hegemony is huge and scattered. However our meta-analysis reveals various commonalities. Our key finding is that there is a common set of cycle periods that is common across most socio-economic variables. 相似文献

We show that a monopolistic final goods producer may find it profitable to create competition by licensing its technology
if the input market is imperfectly competitive. With a centralized union, we show that licensing by a monopolist is profitable
under both uniform and discriminatory wage settings by the union. However, the incentive for licensing is higher under the
former situation. We also show that licensing by the monopolist is profitable under both quantity and price competition, and
the incentive for licensing is higher under price competition than under quantity competition. Our qualitative results hold
even with decentralized unions.

Summary The uniform rule is considered to be the most important rule for the problem of allocating an amount of a perfectly divisible good between agents who have single-peaked preferences. The uniform rule was studied extensively in the literature and several characterizations were provided. The aim of this paper is to provide two different formulations and corresponding axiomatizations of the uniform rule. These formulations resemble the Nash and the lexicographic egalitarian bargaining solutions; the corresponding axiomatizations are based on axioms of independence of irrelevant alternatives and restricted monotonicity.The authors are grateful to Jeffrey Banks, Steve Ching, Vincent Feltkamp, Bezalel Peleg, Sang-Young Sonn, William Thomson and an anonymous referee for helpful comments. 相似文献

This paper suggests that while the static welfare losses of merger predilections among Western firms may not be dramatic, they may lead to substantial dynamic losses when merger-prone firms need to compete with firms which instead focus on equipment investment and investments in R&D. It is suggested that such diverging investment priorities have been the real cause of the deteriorating competitiveness of many of the largest Western enterprises vis-à-vis their Japanese rivals. While mergers are generally taken to be determined by either efficiency or monopoly considerations, this paper argues that Western merger predilections are likely to be generated by a combination of imitative and defensive routines as well. That would make it difficult for firms to unilaterally break away from these competitiveness-threatening investments. If correct, this would imply that competition policies would need to be refocused. However, it is also suggested that the implications for international competitiveness should make merger questions a subject of industrial policies too. In that respect, the paper suggests some basic attitudinal changes.Earlier versions of this paper were presented at a Global Forum for Competition and Trade Policy conference in Vienna and at a EUNIP workshop at Åbo Akademi University, Finland.

In the last three decades much knowledge has been produced on how best to conduct foresight exercises, but little is known on how foresight should be integrated with the innovation effort of a company. Drawing on empirical evidence from 19 case studies and 107 interviews, we identify three roles that corporate foresight should play to maximize the innovation capacity of a firm: (1) the strategist role, which explores new business fields; (2) the initiator role, which increases the number of innovation concepts and ideas; and (3) the opponent role, which challenges innovation projects to increase the quality of their output. 相似文献

For the connections model of strategic network formation, with two-way flow of information and without information decay,
specific parameter configurations are given for which Nash networks do not exist. Moreover, existence and the scope of Nash
network architectures are briefly discussed.
We would like to thank two referees for helpful comments. 相似文献

In this paper we consider deterministic seasonal variation in quarterly industrial production for several European countries, and we address the question whether this variation has become more similar across countries over time. Due to economic and institutional factors, one may expect convergence across business cycles. When these have similar characteristics as seasonal cycles, one may perhaps also find convergence in seasonality. To this aim, we propose a method that is based on treating the set of production series as a panel. By testing for the relevant parameter restrictions for moving window samples, we examine the hypothesis of convergence in deterministic seasonality while allowing for seasonal unit roots. Our main empirical finding is that there is no evidence for convergence in seasonality. 相似文献
