Consumer information programs can be more effective if they are conceived within a marketing framework which views consumer information as a product to be marketed. A methodology is outlined which can assist consumer information program developers in identifying information needs from the consumer's point of view, rather than the policy maker's.

This paper is concerned with the effects of capital risk on optimal individual savings decisions in a simple two-period setting. We investigate the respective roles played by risk and time preferences in answering the following related questions: Q1: Will savings increase, remain constant or decrease in response to an increase in capital risk? Q2: Is optimal saving in the presence of capital risk greater than, equal to or less than optimal saving in the certainty case where the rate of return equals the mean (uncertain) return?

This paper studies economic policy toward feed grain and livestock markets by applying optimal control theory to a quarterly microeconometric model.

In this paper we consider a set of denumerable stochastic matrices where the paramter set is a compact metric space. We give a number of simultaneous recurrence conditions on the stochastic matrices and establish equivalences between these conditions. The results obtained generalize corresponding results in Markov chain theory to a considerable extent and have applications in stochastic control problems.

A global portrait of the phase plane for a fishery model is obtained for any acceptable values of the parameters. Three different structures of the phase plane are recovered. The first predicts an eventual collapse of the fishery. The second predicts an unstable limit cycle and an eventual stability of solutions which start inside the limit cycle. The last structure predicts two possible stable equilibria, one with high catch rate, and the other with no catch. Each structure corresponds to a different domain in the parameter space.
