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
Water scarcity in the Western United States has been the focus of recent policy discussion. Researchers and policymakers agree that the implications of water scarcity are severe and widespread, and as such have stressed the importance of addressing water allocation in the short term and long term. However, this urgency has led to some short-term solutions, like rotational fallowing, being implemented without evaluation, or some long-term solutions, like re-structuring of rights, being suggested without precedent. This dissertation aims at reducing the gap between proposed solutions, existing data, and program evaluation by developing and analyzing two novel datasets useful for causal identification, evaluating both a long-term and short-term approach to water scarcity with these data, and finally demonstrating the ability of overlapping institutions to respond to increasing weather variability. Chapter 1 evaluates a short-term approach, rotational fallowing, and identifies the impact of this approach on water savings. Chapter 2 develops novel trade panel data and exploits the only share-based water market in the US: the Colorado-Big Thompson Project. This chapter compares trade and crop choice outside of the CBT, to those same outcomes within the CBT, and identifies the differences. Chapter 3 expands on crop choice within the CBT and identifies the extent to which overlapping institutions can mediate weather variability compared to prior appropriation.
