In this paper we derive an exact relationship between the net investment at a given point in time and future consumption plans. Our result is general in the sense that it neither requires a constant rate of time preference nor an exponential discount function. One interpretation of the result is...

Previous studies indicate that the general public would prefer to reallocate medical resources from old people to young ones, and also has a low WTP for measures that increase the survival probability at an advanced age. In this paper, we present an analysis of the value of a ‘blip’, i.e. an...

In this paper we consider the possibility of using ‘green’ welfare change measures as the basis for cost-benefit analysis of new projects. Such green welfare change measures look very similar to what one would expect a cost-benefit analysis of the entire economy to look like. It is shown...

In this note, we analyze the behavior of a firm that has a (stochastic) market power due to a patent. For example, we show how to handle the stock aspects of R&D activities (the accumulation of human capital in a firm). In fact, when the R&D stock enters the survival probability of the firm's...

This paper concerns international coordination of environmental taxation. The main purpose is to study the global welfare effects that will arise, if there is an agreement between countries to slightly increase their emission taxes. We show that even if each individual country has chosen its...

This paper contains a fairly brief, but self-contained, version of the history of welfare economics, as well as the more modern welfare results. We introduce public goods and asymmetric information, and we hint at some of the modern mechanism design results. The paper also contains a section on...
