It is known that overlapping generations models with imperfectly competitive firms may exhibit a continuum of stationary equilibria. The reason of this indeterminacy is that different price expectation functions of consumers lead to different objective demand functions against which firms...

We depart from the assumption of perfect competition in the final goods sector, commonly used in cash-in-advance (CIA) models, providing extensive theoretical analysis of the general equilibrium of an economy with imperfect competition, endogenous production and fully flexible prices in the...

We use a dynamic general-equilibrium model to study how removing barriers to competition in the nontraded goods sector affects the current account of a small open economy. We show that the expansion of the nontraded sector that results from such a "deregulation shock" is associated with an...

This paper explores the impact of product liability on vertical product differentiation when product safety is perfectly observable. In a two-stage competition, duopolistic firms are subject to strict liability and segment the market such that a low-safety product is marketed at a low price to...

This paper studies the market and welfare effects of two main tax reforms - the Corporate Business Income Tax (CBIT) and the Allowance for Corporate Equity tax (ACE). Using an imperfect-competition model for a small open economy, it is shown that the well-known neutrality property of ACE does...

In many markets, user benefits depend on participation and usage decisions of other users giving rise to network effects. Intermediaries manage these network effects and thus act as platforms that bring users together. This paper reviews key findings from the literature on network effects and...

This paper provides a novel rationale for the regulation of market size when heterogeneous firms compete. A regulator seeks to maximize total welfare by choosing the number of firms allowed to enter the market, e.g. by issuing a certain number of licenses. Opening up the market for more firms...

This paper studies commodity taxation in a model featuring heterogeneous consumers, imperfect competition, and tax salience. We derive new formulas for the incidence and marginal excess burden of commodity taxation highlighting interactions between tax salience and market structure. We estimate...

Industrial prices of goods and services are a function of costs of production and of the mark-up that firms apply on those costs. If these prices relate to goods that are traded internationally, they will also be influenced by the price at which those goods are exchanged in international...
