The new economic geography (NEG) aims to explain long-term patterns in the spatial allocation of industrial activities. It stresses that endogenous economic processes may enlarge small historic differences leading to quite different regional patterns—history matters for the long-term geographical distribution of economic activities. A pivotal element is that productive factors move to another region whenever the anticipated remuneration is higher in that region. Given the long-term nature of NEG analyses and the crucial role of expectations, it is astonishing that most of the existing models assume only naïve or myopic expectations. However, a recent stream of the literature in behavioral and experimental economics shows that agents often use expectational heuristics, such as trend extrapolating and trend reverting rules. We introduce such expectations formation hypotheses into a NEG model formulated in discrete time. This modification leads to a system of two nonlinear difference equations (corresponding, in the language of dynamical systems theory, to a 2-dimensional piecewise smooth map) and thus enriches the possible dynamic patterns: with trend extrapolating (reverting) the symmetric equilibrium is less (more) stable; and it may lose stability only via a flip bifurcation (or also via a Neimark–Sacker bifurcation) giving rise to a period-doubling cascade (or also to quasi-periodic orbits). In both cases, complex behavior is possible; multistability, that is, the coexistence of locally stable equilibria, is pervasive; and border-collision bifurcations are also allowed. In this sense, our analysis corroborates some of the basic insights of the NEG. 相似文献

We study the decisions of a politician who maximizes his probability of being re-elected, which depends on the enactment of legislative instruments defined ‘scandalous’ because of their highly redistributive content. The agents are a politician and the voters; the legislative instruments available to the legislator are ordinary and executive laws, which differ according to their visibility. The theoretical model predicts that ‘scandalous’ legislation tends to be passed at the beginning of the legislature, while ‘non scandalous’, broader legislation, is approved mostly at the end of the legislation. Scandalous decisions, moreover, tend to be implemented by means of less visible executive legislation, while ordinary acts are mainly used to implement non scandalous decisions. This explanation of the genesis of legislation cycles is consistent with the findings of the empirical literature. 相似文献

We revisit the Cournot–Bertrand debate in the light of Cournot, Edgeworth and Launhardt, tracing back to Launhardt the origin of price competition in duopoly models with constant returns to scale. Then, we discuss the formalisation of consumer utility function for differentiated products, first appearing in Launhardt and then in Bowley. This allows us to point out that assuming that firms know the demand function(s) is equivalent to assuming that they know the structure of consumer preferences. Therefore, we argue that there is no role for the auctioneer, either in Cournot or in Walras. 相似文献

Although many scholars have demonstrated that companies engaged in collaborations achieve better environmental performance than other companies, existing studies have not analyzed in depth whether this effect changes considering the characteristics of cooperation. Our paper aims to explore whether collaboration with other companies always has a positive effect on environmental performance or whether it depends on cooperation goals, collaboration type, or company size. Empirical analysis based on a sample of 773 European companies demonstrated that an external source of knowledge is an important way to foster firms' environmental proactivity, especially when environmental goals are shared at the basis of collaboration. Second, we verified that companies involved in JVs with environmental goals achieve greater environmental performance than companies that use M&As to acquire external knowledge. Finally, we demonstrated that it is more important for small companies to be involved in environmental collaboration than larger ones. 相似文献

This article studies the relationship between the production of the Mediterranean border between Italy and Tunisia, and Italy’s internal geographies of uneven development, commonly known as the 'Southern Question’. Through a study of contemporary Tunisian migration to Sicily in relation to turn of the 20th century Sicilian southward migration to French Protectorate Tunisia, it claims that Sicilians were made into Italians and Europeans through their relationship with Tunisians, and that Sicily was produced as Europe through the progressive demarcation and fortification of the Mediterranean border. Drawing on literature on colonial socio-spatial differentiation, internal colonialism and postcolonial analyses of migration to Europe, this article reframes current debates around the ‘integration’ of migrants as part of longer-term questions around the incorporation of ‘difference’ into the body-politic of the nation—questions that were historically posed in relation to colonial subjects and populations of metropolitan peripheries. Thus, the article considers current debates around the incorporation of migrants as part of a longer-term process of definition of the ‘civilizational’ boundaries of Europe. 相似文献

The paper uses unique data on contracts concluded by providers of home care to evaluate the effect of provider market power on prices of home care services in the Netherlands. Since, at least in some regions, one or two providers dominate the market, there are concerns about the effect of providers’ market power on the pricing of home care services. Using data on contracted prices and quantities for 2004–2006, we find that providers with a larger market share are able to contract at a higher price. The effect remains after controlling for quality. 相似文献

The aim of this paper is to investigate a vertically differentiated market served either by a multiproduct monopolist or by duopolists, in which a public authority aiming at increasing the welfare level can choose among two instruments, namely, quality taxation/subsidisation, and minimum quality standard. In the monopoly case they are equivalent as to the social welfare level, in that both allow the regulator to achieve the second best level of social welfare he would attain if he were to set qualities under the monopoly pricing rule, while they are not equivalent in terms of the distribution of surplus. In the duopoly regime, we show that there exists a taxation/subsidisation scheme inducing firms to produce the socially optimal qualites. 相似文献

This study proposes brand communities as an effective tool within the integrated marketing communication (IMC) system. The paper utilizes the Brand Concept Map quali-quantitative technique in order to represent and compare mental association texture within one group of non-members of a brand community versus one group of people engaged in the same community. Brand stimulus is Nutella (chocolate cream) which boasts a crowded and lively online brand community: Nutellaville. Results show that brand community is effective in terms of contribution, commonality, and complementarity within the IMC system. In particular, Nutella brand image within the online community participants is composed of some mental associations overlapping other communication tools (commonality), and by new mental associations (complementarity) referred to the brand image dimension named ‘brand as person’ (seductive, popular, reassuring); second, this anthropomorphism effect solves the issue of sense of guilt excited by chocolate (contribution). 相似文献
