In this paper, we rank the relative importance of the exogenous parameters upon the optimal harvesting size in a stochastic rotation problem. We show that when the tree growth follows geometric Brownian motion, the harvesting size is most elastic to the harvesting cost, followed by the interest...

In this paper we show that we can replace the assumption of constant discount rate in the onesector optimal growth model with the assumption of decreasing marginal impatience without losing major properties of the model. In particular, we show that the steady state exists, is unique, and has a...

Purchasing life insurance is for the welfare of young children, par-ticularly preteens, who are liquidity constrained. In this paper, we present a life cycle model of life insurance that takes into account the ages of these young beneciaries. We show that, as the child ages, the need for...

In this paper we present a theory of health investment when there are multiple causes of death. Since there are several risks competing for one's life, the health investments in avoiding different causes of death are not independent in general. We analyze the optimal investment rules and the...

In this paper we present a theory of health investment when there are multiple causes of death. Since there are several risks "competing" for one's life, the health investments in avoiding different causes of death are not independent in general. We analyze the optimal investment rules and the...

This paper studies the interdependence between property insurance and portfolio selection. The insurance premium of property loss is shown to play the role of subsistence consumption in the analysis. Then, "security" becomes a necessity good and an increase in any insurance parameter would make...
