We develop a theoretical model of long-run investment decisions on capacity in the context of a liberalized electricity market. The sector's idiosyncrasies such as the uncertainty surrounding future supply and demand, as well as technological constraints, are explicitly modelled. The model is...

The conventional wisdom is that indirect network effects, unlike direct network effects, do not give rise to externalities. In this Paper we show that under very general conditions, indirect network effects lead to adoption externalities. In particular we show that in markets where consumption...

This paper proposes an explanation of merger waves based on the interaction between competitive pressure and irreversibility of mergers in an uncertain environment. A set of acquirers compete over time for scarce targets. At each point in time, an acquirer can either postpone a takeover attempt,...

Two producers offer differentiated goods to a representative consumer. The buyer has distinct marginal valuations for the quality of the products. Each producer knows perfectly the consumer’s taste for its own product, but remains uninformed about its taste for the rival’s product. When each...

According to standard IO models, the characteristics of market demand (intercept, slope, elasticity) and of the technology (level of symmetric marginal costs) do not play any role in defining the sustainability of collusive behaviors in Bertrand oligopolies. The paper modifies this...

The received wisdom is that sunk costs create a barrier to entry - if entry fails, then the entrant, unable to recover sunk costs, incurs greater losses. In a strategic context where an incumbent may prey on the entrant, sunk entry costs have a countervailing effect: they may effectively commit...

In this paper we investigate the firm-specific factors that account for the decision to invest in low-wage countries on the part of Italian firms in the textiles and clothing sector. This analysis is motivated by the fact that our survey data show, between 1990 and 1997, a decline of average...

The purpose of this article is to investigate the prospects for entry into an existing network in the telecommunication industry, and how public policy may promote a more competitive outcome. We apply a model that captures the fact that the incumbent has an installed base of loyal consumers,...

We compare the social welfare generated by a domestic government in two types of policy set-ups: a ‘commitment’ regime in which government sets its policy instrument before the strategic choice by a domestic firm and a ‘non-commitment’ regime where the policy variable is set after the...

Domestic products have a disproportionately high market share on many goods markets. We examine the contribution of preferences to such "home bias", using detailed data on wine sales in New Hampshire (weekly sales by brand by store for one year). In counterfactual simulations, where we use the...
