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...

Problems dealing with the design and the operations of gas transmission networks arechallenging. The difficulty mainly arises from the simultaneous modeling of gastransmission laws and of the investment costs. The combination of the two yields a nonlinearnon-convex optimization problem. To...

Firms protected by antidumping measures do not unequivocally benefit from them. Antidumpingprotection benefits non-exporters active on the protected market by raising their domestic sales, buthurts exporters of similar products as the protected ones. Export sales of protected firms fall byalmost...

We investigate the impact of changes in international trade and domestic transport costs on the internalgeography of a domestic economy linked to the rest of the World through a hub. We address that issue bydeveloping two three regions model, namely a version of the Footlose Entrepreneur and a...

The imposition of universal coverage and uniform pricing constraints, as part of the universalservice obligations, makes the universal service provider less aggressive in the price game when itcompetes with a firm that does not cover the whole set of markets (Valletti et al., 2002). In...

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 study the short term price behavior of December 2008 future prices for EU emissionallowances. We model returns and volatility dynamics of this price showing that a standard ARMA-GARCHframework is not adequate and that the gaussianity assumption is rejected due to the occurrence...

The heterogeneity of the available physical capital with respect to productivity and emissionintensity is an important factor for policy design, especially in the presence of emissionrestrictions. In a vintage capital model, reducing pollution requires to change the capitalstructure through...

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...

Many papers in the litterature have adopted the expected utility paradigm to analyze insurancedecisions. Insurance companies manage policies by growing, by adding independent risks.Even if adding risks generally ultimately decreases the probability of insolvency, the impacton the insurer's...
