Description
Three demand systems were estimated to examine demand sensitivity and welfare changes for each commodity under study. In the first essay, a Quadratic Almost Ideal Demand System (QUAIDS) was used to examine the effect of the Fukushima Daichi nuclear disaster on the demand for imported pelagic fish in the domestic Japanese market. The effect of the Fukushima Daichi nuclear disaster was measured using changes in demand after the disaster as well as measures of changes in social welfare changes caused by the disaster. A significant effect of the disaster on demand sensitivity measures was found, but no significant changes in welfare. In the second essay, a differential demand system examined the effect of exchange rate fluctuations on the demand for fresh tomatoes in the U.S. Market. It was found that the U.S. Dollar-Mexican Peso exchange rate had a significant positive effect on the demand for Mexican fresh tomatoes. In the third essay, a Hurdle Negative Binomial demand system was estimated for recreational trips to the Boundary Waters Canoe Area Wilderness. This model was estimated using Bayesian methods to obtain parameter estimates that could not be obtained by maximum likelihood. The parameters were used to calculate recreational welfare measures for trips to seventy-two entry points.

Description
One of the newest technologies available for agricultural use is the sequencing of the bovine genome and the identification of specific genes that would ensure favorable physical traits in the herd. An easy way for this technology to be utilized is in the milking herds of dairies, the herd has already been bred for specific traits and any change due to a genomic influence would be easily seen. Dairy cattle are commonly bred through artificial insemination, and this would be a perfect place for the genomic programs to prove themselves. In order to determine the attitudes of local dairymen toward genomics, I designed and administered a survey to gauge their opinions. The survey was given to a meeting of the United Dairymen of Arizona at their Tempe offices. The survey covered the current breeding methods used by the dairies, the desired attributes in a milking herd and a breeding program, and a place for the dairymen to give their own opinions on genomics. The results indicated that the dairymen are interested of using genomics, but they are unsure of the cost. Dairymen are often looking for new methods to increase their milk production and herd value, but are reluctant to pay a high amount. One recommendation is for these dairymen to utilize bulls that have had their genome analyzed when they are breeding their cows. This would allow the dairymen to see the effects and benefits of genomics on their herd without the dairymen having to front the large start up cost for their own genomic program.
