Evaluation of risk strategy and market efficiency in the international coal market: A case study of the Japanese coking coal market.Wang, Tianchi. (The University of Arizona., 1992)Market efficiency and buyers' risk strategy in the Japanese coking coal import market are examined. The Japanese coal market is found to be inefficient, Japanese buyers traditionally have purchased coals from the United States at a high price and, since the second half of the 1980's, have paid the highest average price to Canadian producers. Given the abundant low cost Australian coals, this purchasing pattern does not meet the cost minimization criteria for efficiency. This is explained mainly by the buyers' risk management strategy. To more accurately examine price differentiation, the complexity of coal quality is considered first. A statistical method is used to estimate the quality premium as a cost component in price formation. Next a comparison of supply regions and a detailed investigation on market conduct is based on quality-adjusted prices, which are assumed to represent the prices of homogenous coals. Although various reasons are used by researchers to explain Japanese buyers power, this study finds vertical integration of the Japanese companies to be the most important factor creating that power. A detailed survey of vertical integration is made. Finally, a monetary value of the risk premium is estimated by using the partial elasticity of substitution. Total payments by Japanese coking coal buyers for risk premiums are estimated. These represent the extra dollars paid by the Japanese to US and Canadian coal producers for purchasing their coals instead of Australian coals.
Niche competition in the occupational labor market: An ecological theory of labor market dynamicsRichmond, David A. (The University of Arizona., 2000)This dissertation models occupational wage using a fusion of the economic model of supply and demand and an ecological theory of social groups. I argue that competition between different occupations for similar workers is a key element in determining the amount of labor supplied to occupations, and therefore also determines wages. The model places occupational groups in niches within a social space composed of the sociodemographic dimensions of age, education, race, and gender. Occupations compete in their niches for members with other occupations in the niche. High levels of competition lead to lower levels of supply, and, therefore, higher wages. This approach challenges a key assumption of current approaches to wage determination, namely that human capital dimensions are the only dimensions relevant to wage outcomes, and that the effect of these dimensions is constant and unidirectional. I address several lacuna evident in previous work. The model I present is the first truly structural model of occupational interdependence. The model treats the set of occupations holistically, as a interdependent system, rather than independently. In addition, I introduce price into the theory of community ecology, which has been heretofore ignored in this work. Finally, this dissertation presents a theory which may explain the so called dual labor market wage effect. Data is taken from nine consecutive years of the Current Population Survey (1983-1991). I estimate the rate of change of supply and demand in the occupational labor market using a simultaneous equations model which incorporates the effect of competition along multiple social dimensions. I estimate both unidimensional effects of competition along age and education and multidimensional effects of competition along age, education, race, and gender simultaneously.
RACE, CLASS AND MARKETS: ETHNIC STRATIFICATION AND LABOR MARKET SEGMENTATION IN THE METAL MINING INDUSTRY, 1850-1880.BOSWELL, TERRY E. (The University of Arizona., 1984)A theoretical framework is developed for incorporating class conflict dynamics into accumulation theories of labor market segmentation by analyzing the transaction costs of conflict under varying conditions of economic structure and power resources. The theory has the "bottom up" perspective developed in the "new social history." Skill is treated as a status for which workers struggle and internal labor market hierarchies are considered products of the conflicting strategies between capital and labor. Split-labor market theory is also discussed as a method for explaining why workers discriminate. This theory is amended to distinguish between market and class interests of workers, and to take into account the self-perpetuating economic effects of racist discourse. My historical analysis of the metal-mining industry emphasizes the formation of ethnically stratified segments of the labor market in which Chinese and Mexican workers were denied access to the craft-internal labor market for skilled workers. Competition over mining claims under the threat of takeover by mining companies created ethnic antagonism between Chinese and white independent petty-commodity miners. Discrimination by the white independent miners crowded the Chinese into the labor market, which reduced Chinese wages, and induced conflict between white and Chinese wage workers in the company-mines. Ethnic antagonism in combination with intense class struggle produced a segregated labor market between Mexican miners and Anglo supervisors during the initial proletarianization of the mines. Mexican miners were later displaced by Cornish miners who developed a segregated craft-internal labor market. Analysis of the labor process shows that mechanization initially facilitated the struggle by Cornish miners for a skilled status, contrary to homogenization expectations. Mexican miners were relegated to unskilled manual positions.
