We study the transition between non renewable and renewable energy sources with adjustment costs over the production capacity of renewable energy. Assuming constant variable marginal costs for both energy sources, convex adjustment costs and a more expensive renewable energy, we show the...

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...

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 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)....

This paper examines if an energy price shock should be compensated by a reduction in energy taxes to mitigate its impact on consumer prices. Such an adjustment is often debated and advocated for redistributive reasons. Our investigation is based on a model that characterizes second-best optimal...

We introduce a theoretical framework that contributes to the understanding of the non-communicable chronic diseases (NCDs) epidemics: even if NCDs are not "biologically" communicable, they may spread due to the transmission of unhealthy activities such as unhealthy diet, physical inactivity, and...

In this paper, we address two questions: (i) how should a government pursuing both environmental and redistributive objectives design domestic taxes when redistribution is costly, and (ii) how does trade liberalization affect this optimal tax system, and modify the economy's levels of pollution...
