We consider a firm acting strategically on behalf of its shareholders. The price normalization problem arising in general equilibrium models of imperfect competition can be overcome by using the concept of real wealth maximization. This concept is based on shareholders' aggregate demand and does...

We use the two-factor, two-sector, two-country model of Melvin and Warne (1973) and Markusen (1981), in which the production of one good is monopolized in each country, in order to investigate the role of the price normalization. We illustrate several puzzling effects that occur if the price...

Three sequential models of consumption economies are considered, where consumers´only endowment is money. The existence and unicity of temporary equilibria, the neutrality of money and the validity of quantity theory are investigated. In the first two models "money" is persihable; in the second...

Can policies accelerate the convergence path of dualistic economic growth in a single country, offsetting market failures and making growth transmission channels more efficient? A structural dynamic econometric model, has been set up in order to account for these changes. Three are the main...
