This paper formalizes an empirically implementable framework for the definition of local antitrust markets in retail markets. This framework rests on a demand model that captures the trade-off between distance and pecuniary cost across alternative shopping destinations within local markets. The...

This paper presents a theoretical model to investigate the incentive of private producer and policymaker to reduce seasonality in a given market, where consumers derive different utilities from the consumption of the good in different seasons. The (seasonal) product differentiation is modelled...

In this paper we consider the impact of vertical integration on a retailer's choices of product variety and specific, brand-supporting investment. In an incomplete contract environment, vertical merger encourages investment in integrated supply, and foreclosure of non-integrated manufacturers....

A general theoretical and empirical framework is developed for assessing the potential of a vertically integrated firm to foreclose downstream competitors. Using this framework a policymaker may also evaluate the empirical welfare effects from a vertically integrated firm raising rivals' costs....

A mandatory open-network-provision (ONP) by dominant firms is the appropriate government regulation in the presence of network externalities. For basic telephone services and online services, a permanent ONP regulation seems indispensable, whereas telecommunication networks only require...

In this paper we incorporate the two most prominent approaches of inequality aversion, i.e. Fehr and Schmidt (1999) and Bolton and Ockenfels (2000) into an otherwise standard New Keynesian macro model and compare them with respect to their influence on the long-run effectiveness of monetary...

International migration not only enables individuals to earn higher wages but also exposes them to new environments. The norms and values experienced at the destination country could change the behavior of the migrant but also of family members left behind. In this paper we argue that a brain...

We develop a theoretical model of human skill formation and emigration. Additionally to existing brain drain models, we partly endogenize the heterogeneity of the individuals, by introducing aspirations. Emigration of an individual will result in a migration experience, which increases the...

Following Driscoll and Holden (2004), I model forward-looking workers who consider it unfair if a wage adjustment fails to match past inflation. However, the present paper proposes a much larger effect by using the job finding rate as the measure of workers' opportunities outside the firm rather...

In mainstream economics individuals are supposed to be driven only by their self-interest. By contrast, surveys clearly show that people do care about fairness in their demand for redistribution. In this article, in the spirit of the new synthesis in moral psychology (Haidt, 2007: The new...
