On monopolistic competition and optimal product diversity: workers' rents also matter

Abstract .  In the Dixit-Stiglitz model of monopolistic competition, entry of firms is socially too small. Other authors have shown that excess entry is also a possibility with other preferences for diversity. We show that workers' rents also contribute to explain excess entry through a general equilibrium mechanism. Larger wages indeed raises the aggregate earnings and firms sales and profits, which entices too many firms to enter. We discuss the possibility of over-provision of varieties by comparing the equilibrium to unconstrained and constrained social optima and to other regulatory frameworks where wages are not controlled.     

Prune or cut down: salience and Sugden’s <Emphasis Type=\"Italic\">The Economics of Rights</Emphasis>, <Emphasis Type=\"Italic\">Co</Emphasis>-<Emphasis Type=\"Italic\">operation and Welfare</Emphasis>

In The Economics of Rights, Co-operation and Welfare (1986), Robert Sugden follows the tradition from Thomas Schelling and David Lewis in ascribing a central role to the notion of salience within his theory of convention. However, against this, Bruno Verbeek (Instrumental rationality and moral philosophy, Kluwer, Dordrecht, 2002) has argued that an empirically adequate notion of salience may not be incorporated into a generic account of convention without circularity obtains. This paper examines Verbeek’s argument against a background of experimental as well as theoretical work on coordination problems. It finds that the argument fails to consider at least two candidate theories of salience that may be incorporated into the theory of convention without circularity: cognitive hierarchy theory that iterates Sugden’s notion of psychological salience and Schelling salience. Thus, in the end Verbeek’s criticism of the role ascribed to salience in theories of convention may be dismissed, though its discussion draws a fruitful perspective.     

Web-based permission marketing: Segmentation for the lodging industry

Permission marketing is becoming an important tool in maintaining relationships with travelers via the Internet. Its growing importance can be seen in tourism marketing, specifically in the lodging industry. With an increase in industry use, the effectiveness of this technique needs assessment. This paper initiates this process by examining current methods used to collect contact information for the purpose of permission marketing. Three segments of the market are identified and compared based upon their willingness to supply contact information. Significant differences were found in socio-demographics, online habits, trip characteristics, and website design preferences. Implications for lodging marketers are presented and future research topics are discussed.     

The relationship of perception of time and attributes of leisure in daily experiences

The purpose of this study was to explore the relationship between perceived passage of time (slowly versus quickly) and perceived freedom, enjoyment, interest and subjective meaning of leisure in daily experiences of married couples. Eleven college-age married couples participated in this study. Data were collected using experience sampling method that produced a total of 650 self-reports. Couples were signalled at random five times a day for one week. Using logistic regression results suggest that some leisure attributes are more relevant in influencing perception of passage of time in husbands' and wives' daily experiences.     

On structural inelasticity of modal substitution in freight transport

At the European level there is an increasing focus on how freight transport can be moved from trucks on roads to more environmentally friendly modes such as rail and ship. A large proportion of the transport services between OD pairs, however, cannot be substituted since there is only one alternative available. The paper investigates the magnitude of this “structural inelasticity” of modal substitution in freight transport due to a sparser layout of rail and ship-based freight networks compared to road. In the analysis we use a recent Scandinavian freight demand model covering more than 800 zones. We find that the structural inelasticity is very significant - in particular for transportation over less than 500 km. Moreover, the inelasticity varies greatly with commodity groups and between OD pairs, and it depends strongly on the port and rail infrastructure. The results suggest that pure charging instruments (road pricing for trucks) in many regions will have limited mode substitution impacts. However, if combined with structural changes in terms of improved infrastructure for rail and ship, impacts may be greater.     

Trust and corruption revisited: how and why trust and corruption shape each other

Graeff and Svendsen argue that low trust leads to corruption but corruption does not lower trust. I challenge this argument as well as their critique of Uslaner. I present evidence to show that there is a reciprocal relationship between trust and corruption.
