Essays on the Economics of Automobile Fuel Economy
This dissertation consists of three chapters that analyze issues relating to automobile fuel economy. Chapter 1 discusses automobile fuel economy regulations in the United States. The new U.S. Corporate Average Fuel Economy (CAFE) standards not only tighten the target fuel economy to be achieved by automakers, but also make significant changes to the design/structure of CAFE standards by introducing three policy instruments (footprint-based targets, intra-firm transferring of fuel efficiency credits between passenger cars and light trucks, and inter-firm trading of fuel efficiency credits). While there are a number of previous studies on the impact of tightening CAFE standards, economists have paid little attention to the design of CAFE standards. I use policy simulation to evaluate these policy instruments relating to the design of CAFE standards. First, I model and estimate the demand- and supply-sides of the U.S. vehicle market using various data sets. Then, based on the estimation results, I simulate the vehicle market and the demand for driving under four counterfactual CAFE policies with different designs, and examine the impacts of the three policy instruments. Simulation results suggest: (1) footprint-based targets have little impact on market shares, producer profits, consumer surplus, and gasoline use; (2) inter-firm credit trading lowers overall compliance costs by about 75 (in 2000 U.S. dollars), and that for the same case, the average total price of fuel economy is $1,950. We also find that larger, less fuel efficient vehicles tend to have higher marginal and total prices of fuel economy.
Chapter 3 examines whether Japanese fuel economy regulations established in the 1990s induced technological progress in Japanese automakers' technology for providing fuel economy. By observing how fuel economy of automobiles has improved after controlling for changes in vehicle characteristics such as weight and power, I find that fuel economy improvement accelerated after regulations were introduced, implying induced innovation in fuel efficiency technology

Expression of ICAM-I on M cells covering isolated lymphoid follicles of the human colon.
To clarify the immunological function of 'M' (microfold or membranous) cells in the large intestine, we examined the expression of intercellular adhesion molecule-1 (ICAM-1) and HLA-class II antigens immunohistochemically in M cells and follicle-associated epithelia (FAE) covering isolated lymphoid follicles of the human colon in comparison with their expression in Peyer's patches of the small intestine. In Peyer's patches of the small intestine, ICAM-1 was not expressed on the epithelial cells covering the lymphoid follicles, but their cell surfaces were stained positively for HLA-DR. In contrast, colonic M cells expressed ICAM-1 on their cell surfaces but were negative for HLA class II antigens. By immunoelectron microscopy, ICAM-1 was seen to be distributed on the surface of microfolds, on the membranes of apical vesicles and on part of the basolateral plasma membranes of M cells, but was not expressed on adjacent FAE. These findings imply that the M cells in the colon and in Peyer's patches have different immunological roles. In addition, identification of ICAM-1 expression on the colonic M cells should help elucidate the pathogenesis of some inflammatory colonic diseases which appear to start in the lymphoid follicles of the colonic mucosa.</p
