Our paper considers three policies in the design of offshore oil and gas lease sales that will help promote an economically efficient program of energy exploration and development on the Outer Continental Shelf. The first policy, having the government select when specific tracts should be...

The purpose of this brief comment is to provide some empirical data to support the relevance of the theoretical arguments put forward in Donald Hausch's paper (Hausch, Donald B. 1986. Multi-object auctions: sequential vs. simultaneous sales. Management Sci. 32.). There are two different kinds of...

The ´Portfolio Selection Problem´ is traditionally viewed as selecting a mix of investment opportunities that maximizes the expected return subject to a bound on risk. However, in reality, portfolios are made up of a few ´asset classes´ that consist of similar opportunities. The asset...

In this paper we present an algorithm for solving mathematical programming problems of the form: Find x - (x₁,..., x_n) to minimize \sum \varphi _i(x_i) subject to x \in G and l < x < L. Each \varphi _i is assumed to be lower semicontinuous, possibly nonconvex, and G is assumed to be closed. The algorithm is of the...</x>

This paper presents an algorithm for determining the minimum cost schedule of tasks in a critical path network in which task cost-time curves may be concave. A computer program for the case of cost-time curves that are piecewise linear in two segments is described, and a numerical example is...
