We back out an estimate of a personal discount rate of between 3 and 4 percent for a person with a life expectancy of 74 years who dies at age 30 (or 40) and has a value of statistical life of $6.3 million. Central to these calculations is the series generated by Murphy and Topel of value of...

We draw on Ricardian comparative advantage between distinct persons to map out the division of labor among proto-humans in a village some 1.7 million years ago. A person specialized in maintaining a cooking fire in the village is of particular interest (Ofek [2001]). We are also interested in...

We find that a discount rate of 3.8% allows us to derive the schedule of "value of life years" in Murphy and Topel [2006] from their schedule of "value of remaining years of life", this latter presumably being based on a "value of statistical life" of $6.3 million. We draw on the Makeham...

We set out an open, monocentric city with residential structures and reflect on how changes to an amenity index affects the city. On the production side, the shock is represented by a productivity improvement and a local wage increase and on the consumption side the shock is represented by an...

Kolstad's (1994) model of intertemporal, competitive supply to a linear market from two distinct exhaustible resource deposits admits two different interior solutions - one with the low cost deposit "earning" the higher resource rent and the other with the low cost deposit "earning" the lower...

We solve for an S-shaped schedule for market size for a new product that undergoes gradual widespread adoption. We hypothesize that the speed of market expansion is positively related to the current profit per unit being produced. In a mature market the unit profit is relatively low.

We take up three variants of Solow [1974], each with population change endogenous. When each model exhibits sustainability the same three conditions are satisfied: (i) investment in produced capital is funded by resource rents plus "extra" saving, (ii) "extra" saving funds the same two gaps...
