Humans exhibit much more sharing of food harvested by prime-age hunter-gatherers with dependents relative to such sharing by lower-order primates. We investigate this behavior in a model in which a father provides generously to his dependent child-son in period t in the hope that this gesture...

We link daily price-changes for 11 Dow-Jones companies for 5 three month periods to the prevailing interest rate. In "normal times", the interest carrying cost of owning a share exceeds average price change. In periods of high volatility (eg. August to November, 2008), average price change...

We translate Hotelling's continuous-time, exhaustible resource extraction Model of 1931 into a linear program of present value extraction cost minimization subject to a stock endowment and period by period demand constraints. The appropriate form of the demand constraints allows for resource...

We report on the nature of a utility optimizing transfer from one regional government to another when local public goods are present. Computer examples reveal that small differences in regional endowments result in large differences in equilibrium outcomes for two regions, under optimal...

We set out a model of a two-good, small open economy exporting a traditional exportable in order to finance capital goods rental payments. We observe that the traditional export sector declines with an exogenous increase in the country's oil export earnings, while the local goods sector expands....

We take up a growth model with both skilled and unskilled labor, and a steady migration of some unskilled workers, who undertake apprenticing, to the skilled group of workers. Apprenticing involves a period of observing and thus labor output foregone. The time-out for observing represents a cost...

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 set out a simple four sector macro model of the economy of the Roman Empire during a period of considerable economic prosperity. Our focus is on gold coins as currency and the seignorage which the government used to fund its activities. We solve numerically for a balanced growth...
