This paper presents an empirical examination of oligopoly pricing and consumer search. The theoretical model allows for sequential and non-sequential search and, using the theoretical restrictions firm and consumer behavior impose on the data, we study the empirical validity of the models. Two...

In transition and developing countries, we observe rather high levels of corruption even if they have democratic political systems. This is surprising from a political economy perspective, as the majority of people generally suffers from high corruption levels. Our model is based on the fact...

A rational-expectations equilibrium with positive demand for financial information does exist under fully revealing asset price - contrary to a wide-held conjecture. Generalizing the common additive signal-return model with CARA utility to the family of distributions with moment generating...

We study a strategic model of dynamic trading where agents are asymmetrically informed over common value sources of uncertainty. There is a continuum of buyers and a finite number n of sellers. All buyers are uninformed, while at least one seller is privately informed about the true state of the...

Early-stage uncertainty makes the initial cost of capital greater than the expansion-stage one. Tax effects on enterprise formation, entrepreneurial effort and quality, and on capital costs are derived. For an incorporated enterprise (i) the entrepreneur's ability threshold rises with the tax...

We construct a two-good general equilibrium model of international trade for two small open economies where pollution from production is transmitted across borders. Governments in both countries impose emission taxes non-cooperatively. Within this framework, we examine the effect of trade...

Numerical simulation exercises to analyze the impacts of potential changes in non-tariff policies commonly use ad valorem equivalent tariff treatment even though estimated impacts using explicit model representation and ad valorem equivalent treatments will differ. The difficulty for modellers...

This paper looks at a model in which two countries trade agricultural and manufactured commodities. The manufactured-goods sector produces with increasing returns to scale under conditions of monopolistic competition. It is shown that an increase in land endowment (or an increase in agricultural...

A system of tradable permits in the standard setting is effective in attaining the policy objective with regard to pollution reduction at the least cost. This outcome is challenged in case of a tradable permit system in a federal state with individual states having discretionary power regarding...

This paper revisits the debate about the appropriate differential equation that governs the evolution of knowledge in models of endogenous growth. We argue that the assessment of the appropriateness of an equation of motion should not only be based on its implications for the future, but that it...
