This paper studies competition in commodity taxation and product market regula- tion between trading partner countries. We present a two-country general equilibrium model in which destination-based commodity taxes finance public goods, and prod- uct market regulation affects both the number of...

This paper analyzes the impact of foreign investments on a small country's economy in the context of international competition. To that end, we model tax and infrastructure competition within a differential game framework between two unequally sized countries. The model accounts for the widely...

In this paper, we analyze a vertically differentiated mixed duopoly in medical care services. Pollution is the source of illness. The government has a dual role. It decides how much to invest to reduce the pollution level and it may participate in the health market running a public hospital. We...

This paper explores how social interactions among consumers shape markets. In a two-country model, consumers meet and exchange information about the quality of the goods. As information spreads, the demands evolve, affecting the prices and quantities manufactured by profit-maximizing firms. We...

In this paper, we present a model of endogenous vertical integration and horizontal differentiation. Thereexists two output brands and two versions of the input. The only mean for output differentiation is the inputversion used in output production. Firms may choose to vertically integrate to...

In this paper we give an example in which the price of tradeable emission permits increasesdespite firms' adoption of a less polluting technology. This is in contrast with Montero (2002) andParry (1998), among others. If two Counot players switch to a cleaner technology, the price forpermits may...

In this paper, we analyse competition among jurisdictions to attract firms through low taxes oncapital and/or high level of public goods, which enhance firms’ productivity. We assume that thecompeting jurisdictions are different in (population) size and that the mobility of capital is...

In this paper, we propose an example of successive oligopolies where the downstream firmsshare the same decreasing returns technology of the Cobb-Douglas type. We stress thedifferences between the conclusions obtained under this assumption and those resultingfrom the traditional example...

In this paper we analyze how the technology used by downstream firms can influence inputand output market prices. We show via an example that both these prices increase under adecreasing returns technology while the contrary holds when the technology is constant....

In this paper, we address the incentives to invest in environmental innovation of enterprisesthat exercise market power in the output market and also buy and sell pollution permits.Differently from the existing literature, using a market approach we explicitly model theinteraction between the...
