Environmental policy often has to be devised under informational constraints,like uncertainty and asymmetric information. We consider an environmentalpolicy that aims at reducing the welfare losses caused by asymmetricinformation while being sufficiently simple for implementation. Inthis policy,...

A longstanding theoretical discussion on the merits of prices vs.quantities for regulating emissions under uncertainty exists in environmentalpolicy literature. However, empirical evidence w.r.t. instrumentchoice has not been put forward so far. In particular, verylittle is known about...

This paper explores implications of climate change for fiscal policy by assessing theimpact of large scale extreme weather events on changes in public budgets. We applyalternative measures for large scale extreme weather events and conclude that thebudgetary impact of such events ranges between...

Natural catastrophes attract regularly the attention of media and have become a source of public concern. From a financial viewpoint, natural catastrophes represent idiosyncratic risks,diversifiable at the world level. But for reasons analyzed in this pap er reinsurance markets are unable to...

The "common effect" model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental...

This paper explores how cross-sectional data can be exploited jointly with longitudinal data,in order to increase estimation efficiency while properly tackling the potential bias due tounobserved individual characteristics. We propose an innovative procedure and we show itsimplementation by...

Many aspects of the economic transition which started in 1989 in Poland are by nowcomplete. However, the route Polish governments have so far taken concerning the systemof support for low-income families still implies very different poverty alleviation schemescompared to those found in many...

This paper uses British panel data to investigate single women´s labour supply changes inresponse to three tax and benefit policy reforms that occurred in the 1990s. These reformschanged individuals´ work incentives and we use them to identify changes in labour supply.We find evidence of small...

Both raw intuition and past experience suggest that the success of an employment guaranteescheme (EGS) in safeguarding the welfare of the poor depends both on the wage itpromises, and the ease with which any worker can gain access. An EGS is thus at once awage guarantee and a rationing device....

The Polish tax and benefit system is presented in the context of a recently developedmicrosimulation model, SIMPL. The model allows simulating direct taxes, social contributionsand public benefits in Poland for the years 2003 and 2005...>br>
