Jovanovic, Boyan and Saul Lach (1989). "Entry, Exit, and Diffusion with<br />

Learning by Doing." The American Economic Review, 79(4):690-699.<br />

Early entry has the advantage <strong>of</strong> higher revenues per unit <strong>of</strong> output<br />

early on. Late entry has the benefit <strong>of</strong> learning from the experience <strong>of</strong><br />

earlier entrants, and hence lower production costs. These advantages are<br />

balanced <strong>of</strong>f in a continuous time perfect foresight equilibrium. Competition<br />

generates S-shaped diffusion, and staggered entry and exit. A monopolist will<br />

innovate less than a competitive industry, but the innovation that he does do,<br />

he will do sooner.<br />

"Production Costs <strong>of</strong> Juvenile Penaeid Shrimp in an Intensive<br />

Greenhouse Raceway Nursery System." Journal <strong>of</strong> the World<br />

Aquaculture Society, 19(3):149-160.<br />

This analysis compared the use <strong>of</strong> an intensive nursery raceway system<br />

with direct stocking <strong>of</strong> post-larval shrimp (PLS) into growout ponds. The<br />

intensive raceway system allows two crops to be produced in Texas where only<br />

one crop is feasible with direct stocking. Both investment and operational<br />

costs are analyzed for three types <strong>of</strong> greenhouses and three types <strong>of</strong> raceways<br />

where the types vary in cost and lengths <strong>of</strong> life. Three growout pond stocking<br />

densities and two farm sizes were evaluated for each combination <strong>of</strong> greenhouse<br />

and raceway type. Investment costs ranged from $142,000, for the small farm<br />

using the least expensive greenhouse and raceway and utilizing the lowest<br />

stocking density, to about $2.3 million, for the large farm using the most<br />

expensive greenhouse and raceway, respectively, per 1,000 one gram juveniles<br />

produced. Under technology available at the time <strong>of</strong> this analysis, direct<br />

stocking growout ponds with PLS and producing one crop per year is more<br />

pr<strong>of</strong>itable than stocking one gram juveniles and producing two crops per year<br />

on the Texas coast.<br />

Shrimp have supported the most valuable fishery in the United States for<br />

many years. Although the fishery for the cold water species Crangon and<br />

Pandalus has increased in recent years in the New England and Alaska areas,<br />

the mainstay is still the penaeid shrimp <strong>of</strong> the southeastern United States.<br />

Three species make up the bulk <strong>of</strong> the catch, Penaeus aztecus, P. duorarum, and<br />

P. setiferus. The center <strong>of</strong> this fishery is in the Gulf <strong>of</strong> Mexico and along<br />

the southeastern seaboard <strong>of</strong> the United States. The average annual catch <strong>of</strong><br />

penaeids over the past 25 years has been close to 100,000 tons in those areas.<br />

Production in recent years from other countries in the CICAR area, including<br />

Brazil, has been 70,000 tons; worldwide the total annual catch is close to<br />

700,000 tons. Minor periodic annual variations in production have occurred,<br />

attributed generally to adverse environmental or economic factors. Although<br />

the shrimp bycatch problem was long known in the United states, it was not<br />

until late 1972 that a project was implemented to study the situation. Basic<br />
