This paper studies the properties of the social utility function defined by the planner's problem of Constantinides (1982). We show one set of restrictions on the optimal planner's policy rule, which is sufficient for constructing the social utility function analytically. For such well-known...

We examine the investment decision problem of a group whose members have heterogeneous time preferences. In particular, they have different discount factors for utility, possibly not exponential. We characterize the properties of efficient allocations of resources and of shadow prices that would...

This paper extends the aggregation theorems of Zhou (1997) to incorporate a social preference for randomization. We establish variations of Harsanyi’s utilitarianism theorems for general societies in which there exists a set of welfare weights, and a maxmin rule is applied.

In a recent work by Dolan and Edlin it is concluded that no link can be established between cost-benefit analysis (CBA) and cost-effectiveness analysis (CEA). However, the conclusion seems to depend rather heavily on what is understood by a link between CBA and CEA as well as on the exact...
