Using a dynamic model of the control of an infectious disease, we derive the conditions under which eradication will be optimal. When eradication is feasible, the optimal program requires either a low vaccination rate or eradication. A high vaccination rate is never optimal. Under special...

The importance of ecosystem functions for humankind is well known. But only few attempts have been undertaken to estimate the economic value of these ecosystem services. In particular, indirect methods are rarely used, even though they are most suitable for the task. This discrepancy is because...

In order to complete cost benefit analyses of acidification policies, an attempt was made to monetarize the benefits of increased nature quality. So far, several benefits of acidification abatement, such as reduced health risks, had been determined, but the benefits of increased nature quality...

The paper deals with the social and economic dimensions of climate change impacts and adaptation in Italy. The ultimate aim of the paper is to provide policy makers and experts with a conceptual framework, as well as methodological and operational tools for dealing with climate change impacts...

In 1987 the federal government permitted states to raise the speed limit on their rural interstate roads, but not on their urban interstate roads, from 55 mph to 65 mph for the first time in over a decade. Since the states that adopted the higher speed limit must have valued the travel hours...

Recent environmental economics literature regarding global problems, like for example those associated with greenhouse gases, focuses on the emergence of international co-operation and underlying incentives. International co-operation among countries is necessary in the case of global pollution,...

In this paper, we use the two region CETA-M model to explore some related issues raised by the current interest in CO2 concentration targets as a possible climate change policy objective. First, we identify possible cost and benefit assumptions that would make particular concentration ceilings...

The literature of welfare-maximising greenhouse gas emission reduction strategies pays remarkably little attention to equity. This paper introduces three ways to consider efficiency and equity simultaneously. The first method, inspired by Kant and Rawls, maximises net present welfare, without...

The 1998 Kyoto protocol signalled a new earnestness of international intent toward addressing the perceived risk of climate change. Kyoto demands that developed nations turn their economies so as to hit differentiated, sub-1990 level carbon emission targets within the next decade or so. But when...

We discuss the selection of the socially efficient discount rate for public investment projects that entail costs and benefits in the far distant future. We show that the discount rate should be a decreasing function of time horizon under some specific restrictions on the distribution of...
