DO THE JAPANESE DISCRIMINATE AGAINST AUSTRALIAN BEEF IMPORTS?: EVIDENCE FROM THE DIFFERENTIAL APPROACH
This paper considers an application of the differential approach to Japanese demand for beef imports from 1970 to 1993. Results of homothetic demand and negative (significant) own-price elasticities indicate that the Japanese did not discriminate against Australian beef, but the decrease in Australia's trade shares was due to changes in relative prices.Japan, Beef Imports, Rotterdam model, CBS model, International Relations/Trade,
CONVERGENCE OF THE G-7: A COINTEGRATION APPROACH
Income convergence among the G-7 countries was demonstrated using Theil's inequality (entropy) index. G-7 convergence was also found for three potential factors of influence on economic growth: government expenditure, investment expenditure, and industrial employment. Pairwise cointegration tests indicated that income inequality was cointegrated with the other three inequality measures for the time period of 1950-88. Finally, Johansen's I(2) multi-cointegration tests indicated that three of the four inequality measures (i.e. income, investment expenditure, and industrial employment) were cointegrated suggesting that there exists a long-run equilibrium between the inequality in income, investment expenditure, and industrial employment.Agricultural and Food Policy,

Voting rules in sequential search by committees: theory and experiments
We propose a committee extension of the individual sequential search model called the âsecretary problem,â where collective decisions on when to stop the search are reached via a pre-specified voting rule. We offer a game-theoretic analysis of our model, and then report two experiments on three-person committees with either uncorrelated or perfectly correlated preferences under three different voting rules, followed by a third experiment on single decision makers. Relative to equilibrium predictions, committees with uncorrelated preferences over-searched under minority and majority voting rules, but otherwise under-searched or approximated equilibrium play. Individually, committee members were often less strategic when their preferences were uncorrelated than when they were perfectly correlated. Collectively, committeesâ decisions were more strategic than single decision makersâ only under the unanimity rule, though still not significantly better in terms of the decision makersâ welfare. Finally, across our experiments that involved committee search, the unanimity rule always optimized committee welfare
A Cryptosporidium parvum genotype shift between week old and two week old calves following administration of a prophylactic antiprotozoal
This study looked to assess the stability of Cryptosporidium parvum genotypes in calves between the final day of treatment with the antiprotozoal halofuginone lactate and seven days post-treatment. Paired faecal samples were collected on the final day of treatment and seven days later from 54 calves across seven farms in South-west England. The presence of Cryptosporidium species was detected using polymerase chain reaction targeting the 18âs rDNA. The presence and genotype of C. parvum was determined by PCR and amplicon sequencing targeting the gp60 locus. On farms where C. parvum was detected at both sampling times there was a distinct genotype shift. Detection of gp60 genotype IIaA15G2R1 decreased from 40% to 7% while IIaA17G1R1 increased from 0% to 41%, supplemented by IIaA16G3R1 in one sample. A shift in C. parvum genotypes present in calves within a one week sampling timeframe has not been described prior to this study, indicating that the timeframe is likely suitable for observing variation in C. parvum populations and interactions with antiprotozoal control strategies
Karst of Western Cuba: Observations, Geomorphology, and Diagenesis
In Cuba, we observed many karst features in a variety of hydrogeologic settings. These hy-drogeologic settings occur in close proximity only because of the complex tectonic history of the is-land. We observed caves within rocks ranging from Pleistocene to Jurassic, and representing a range of diagenetic ages from eogenetic to teloge-netic. Our observations are from the western one-third of the island of Cuba; however, we believe they are representative of hydrogeologic settings found throughout the island
