Time series procedures are employed to determine the influence of
technological change in inducing factor bias in U.S. agricultural production
between 1948 and 1983. A dynamic measurement error model is used to link
research expenditures to the unobserved technological change variable.
Biasedness in labor and material factor shares is established.
Lambert, David K. and Amin Ussif (1997). A Distance Function Approach to
Multifactor Productivity Measurement in U.S. Agriculture. Presentation
for the Western Agricultural Economics Association, Reno Nevada, July
13-16, 17 pp.
A new procedure is developed to derive estimates of productivity.
Distance function values are calculated between observed netputs and a
reference technology constructed by augmenting observed netputs for quality
changes. MFP growth rates average around 2% over the postwar period.
Discrepancies occur between the distance function estimates and traditional
measures.

"Economic Evaluation of Different Densities for Various Sized
Shrimp Farms in Texas." Journal of the World Aquaculture Society,
24(1):12-22.
There has been a trend toward intensification of shrimp farming in the
U.S. Fifteen simulated farms were used to evaluate economies of scale and to
compare three Penaeus vannamei commercial production strategies: semiintensive,
intensive, and very intensive. Large economies of scale were
associated with each production strategy. Over the range of farm sizes
considered, investment cost per hectare decreased approximately 50% and
production cost decreased approximately 25%. Farms' returns were measured
with Internal Rate of return (IRR). When investment was greater than $0.75
million, the intensive strategy provided slightly better returns to the
investor than semi-intensive or very intensive strategies. At investment
levels less than $0.75 million, the semi-intensive strategy provided the
highest IRR.

Clary (1993). "Estimated Costs and Returns for Catfish Farms With
Recirculating Ponds Along the Upper Texas Coast." Journal of
Agriculture and Applied Economics, 25(2):1-12.
Costs, returns, and economies of scale for small, medium, and large
catfish farms with recirculating ponds are presented for the upper Texas
coast. Internal rates of return are 0.150, 0.183, 0.219, respectively. Total
investment is higher than farms with static ponds but investment per unit
production capacity is 7 percent to 16 percent lower. Average total cost per
pound is between $0.565 and $0.541 (11 percent - 20 percent lower than farms
using current technology). These results have implications for regional
comparative advantage of catfish production as well as incentive for adoption
of new technology in conventional ponds.
Lamkin, John Tillman (1984). A Study of the Galveston Bay Bait-Shrimp
Fishery. Thesis, Wildlife and Fisheries Sciences, Texas A&M
University, College Station, Texas, December, 79 pp.
A study of the bait fish fishery in Galveston Bay, Texas and its impact
on finfish bycatch. Monthly shrimp:finfish abundance rations ranged from
6.4:1 to 1.5:1 with bait shrimp catch of brown and white shrimp. A total of
348,585 kg of finfish were caught in the Galveston Bay bait-shrimp fishery
