Phenomenological Implications of the Topflavor Model

We explore phenomenologies of the topflavour model for the LEP experiment at $m_{_Z}$ scale and the atomic parity violation (APV) experiment in the $C_s$ atoms at low energies. Implications of the model on the $Z$ peak data are studied in terms of the precision variables $\epsilon_i$'s. We find that the LEP data give more stringent constraints on the model parameters than the APV data.Comment: 23 pages (including 5 .eps figs), ReVTeX, the 1st revised version, to appear in Phys.

Effects of Catfish, Crawfish, and Shrimp Imports on U.S. Domestic Prices

Recent increases in imports of catfish, crawfish, and shrimp have caused concern as to their impact on domestic prices. This study seeks to identify the linkages between imports of these goods and producer prices. Increases in imports of catfish and shrimp are shown to decrease related domestic prices. However, recent trends show a simultaneous increase in both imports and domestic prices of crawfish.Resource /Energy Economics and Policy,

Demand System Analysis of the South Korean Beef Market with the Free Trade Demand Model

In this study a demand system analysis for beef in South Korea is constructed. A free trade demand system was used in which the economic welfare of market participants are maximized. Recognizing implicit discrimination about non-locally sourced beef products, this study deduces market demand equations with respect to consumer preference in order to identify the marginal effect of change consumer preference has on market demand.Demand and Price Analysis, International Relations/Trade, Research Methods/ Statistical Methods,
