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

We build a dynamic duopoly model that accounts for the empirical observation of monopoly persistence in the long run. More specifically, we analyze the conditions under which it is optimal for the market leader in an initially duopoly setup to undertake pre-emptive R&D investment, ("strategic...

It is well known that tariff policy can alleviate the negative consequences of breaching intellectual property rights by foreign firms. Yet, the positive effect of tariff protection is thought to be the benefit firms get at the expense of consumers (at least in the short run). Using a set-up in...

Allowing for endogenous entry in the traditional Stackelberg setup with product differentiation, leads to reverting of the standard comparative static and limiting results. Unlike in the standard Stackelberg setup with barriers to entry, the leader's profit increases when the differentiation...

We analyze a simple “tariffs cum foreign competition” policy targeted at enhancing thecompetitive position of a domestic, developing country firm that competes with its developed country counterpart on the domestic market and that carries out an innovative (imitative) effort. We evaluate...

We build a dynamic duopoly model that accounts for the empirical observation of monopoly persistence in the long run. More specifically, we analyze the conditions under which it is optimal for the market leader in an initially duopoly setup to undertake pre-emptive R&D investment ("strategic...

We introduce spillover e¤ect into John Sutton's (1991,1998) concept of endogenous sunk costs. These sunk costs appear in the form of R&D investment into quality in our framework. We show that with spillovers increasing and the effectiveness of investment in raising quality decreas- ing, the...
