The paper develops a model of world frozen shrimp market using data from 1980 to 2004. There is a structural change in the world shrimp market that shifts the market volume from traditional to the non-traditional markets. Market structural change affects shrimp price significantly. Shrimp price has a trend and...
A theoretical model links price risks at processors market to farm supply response. Price risks at wholesale market affect processors‚ factor demand for farm-raised catfish. The fluctuation in factor demand also influence the farm-raised catfish supply response. Price risks at wholesale market reduce processors‚ factor demand for farm-raised catfish, and...
U.S. imported 2.3 million metric tons of smoked herring in 2007 costing $707,000. Hence it is important to investigate factors influencing the importation of smoked herring into the US. We used time series data from 1976 to 2007 to estimate an import demand function: log(Mt) = a0 + a1*log(Pt) +...
The present study uses normalized profit function and adaptive expectation approaches to analyze U.S. catfish farm supply. Empirical estimations give short-run supply elasticity of 0.25 and 0.26 and long-run supply elasticity of 0.47 and 2.1 in each of the two approaches, respectively. Technological improvement is attributed for only 9.8% out...
The public controversy over possible health hazards from radioactive fallout from atomic bomb testing began in 1954, shortly after a thermonuclear test by the United States spread fallout world wide. In the dissertation, I address two of the fundamental questions of the fallout controversy: Was there a threshold of radiation...
Ocean health is a major concern for coastal communities dependent on the ocean for their livelihood. Recent changes in in ocean health force researchers to examine the factors that influence the decline in ocean health. The paper developed production functions using the Global Ocean Health Index (OHI) for 2014 and...
The present study employs a cointegration method and error correction model to analyze the long-run relationship and short-run adjustment of aggregated seafood import demand function for selected Caribbean countries. The results show that there exists a long-term equilibrium relationship between Caribbean seafood import and related factors. Import demand elasticity is...

Catfish production has experienced a decline in the past two years, and farmers have been blaming international competition, exports, low prices and poor feed conversion ratios as the main causes. We evaluate the usefulness of the Analytic Hierarchy Process (AHP) and the Cost Benefit Analysis (CBA) as instruments for rapid...
