This paper presents a theoretical economic model assessing the effects of the level of mandatory genetically modified (GM) / non-GM coexistence regulations on market and welfare outcomes. We assume vertical differentiation of GM and non-GM goods on the consumer side. Producers are heterogeneous...

We look at the effects of physical activity (PA) recommendation policies by considering a social multiplier model in which individuals differ in their concern for PA. The government can either observe this concern (and implement the First Best) or not (and implement a uniform policy). Whichever...

We consider the decentralized provision of a global public good with local external- ities in a spatially explicit model. Communities decide on the location of a facility that benefits everyone but exhibits costs to the host and its neighbors. They share the costs through transfers. We examine...

Due to meteorological factors, the distribution of the environmental damage due to climate change bears no relationship to that of global emissions. We argue in favor of offsetting this discrepancy, and propose a "global insurance scheme" to be fincanced according to countries responsibility for...

High-speed market connections improve investors' ability to search for attractive quotes in fragmented markets, raising gains from trade. They also enable fast traders to observe market information before slow traders, generating adverse selection, and thus negative externalities. When investing...

We study optimal pricing of roads and public transport in presence of nonlinear in- come taxation. Individuals are heterogeneous in unobservable earning ability. Optimal transport tarifs depend on time costs of travel and work schedule adjustments (days and hours worked per day) as a response to...

This paper studies environmental taxation in a Mirrlees setting when energy, a polluting good, is used both as a factor of production and a final consumption good. The model is calibrated for the Czech economy. We study two different tax systems. Both consider a non-linear income tax but the...

This paper analyzes the problem of international environmental cooperation as a coalition formation game. For this purpose, we develop a simple model with three countries of unequal size. Strate- gic interactions between those countries come from the imperfect competition among producers in...

We look at the consequences of allowing public health insurance (PuHI) to be voluntary when its coverage can be supplemented in the market. PuHI redistributes with respect to risk and income, and the market is affected by adverse selection. We argue that making PuHI voluntary does not lead to...

A wide variety of social protection systems coexist within the EU. Some member states provide social insurance that is of Beveridgean inspiration (with universal and more or less flat benefits), while others offer a system that is mainly Bismarckian (with benefits related to past contributions)....
