This thesis consists of two essays on applied microeconomics issues. The first essay presents a hedonic price econometric model of vacant commercial land. The second essay presents cost frontier analysis on the industry and firm's performance of the U.S. Motor Carrier industry. Our hedonic price econometric model includes two new developments in estimating land values in a multicentric urban area First, two composite indexes of market accessibility and highway accessibility are developed to account for the impacts of different characteristics of different regional nodes on land value at a particular site. Second, we use nonlinear least squares to estimate the decay parameters of the accessibility indexes within the model. We found that market accessibility is the dominant land value determinant. The estimated market accessibility decay parameter is different in value from the ones that are commonly assumed in hedonic models. The effect of access to highway interchanges is insignificant. Corner lots are of higher value. Finally, under Seattle's zoning policy, zoning classification of neighborhood commercial and community commercial land does not have significant effect on land value. The second essay uses the stochastic cost frontiers to analyze the performance of the U.S. motor carrier industry in the pre- and post-MCA periods. The average industry inefficiencies were between 14 and 27 percent during studied period. Our results indicate that the deregulation has no impact on industry efficiency. After a short adjustment period, the average industry inefficiency in the post-MCA years falls back to its pre-MCA level of around 14 to 16 percent. We analyzed the firm-specific inefficiencies by tobit regression. Our result shows that union firms are 1.5 and 4 percent less efficient than non-union firms in the pre- and post-MCA years, respectively. Firms located in the southern region are relatively efficient and the ones in the northern regions are relatively inefficient. Our result supports Stigler's Survivor Principle that survivor firms are relatively efficient.The first essay presents a hedonic price econometric model of vacant commercial land.
