Risk assessment of BSE infectivity in the environment from rendering of over thirty month scheme cattle

One of the measures put in place by the UK government following the emergence of new variant CJD and the likely link to BSE in cattle was the exclusion of older cattle from food for human consumption, the so called Over Thirty Month Scheme. Cattle slaughteredunder this scheme are rendered to produce Meat and Bone Meal and tallow for subsequent disposal. Concern was expressed about the liquid waste effluent from one rendering plant, which was being discharged to a soakaway over an aquifer used for public drinking water supply. This risk assessment was carried out for the UK Environment Agency to assess whether the public drinking water supply was safe, and to evaluate alternative options. The study considered both normal effluent and accidental spills, and evaluated the various barriers that affect the amount of infectivity getting into the drinking water supply. The study was able to demonstrate that the risks to people drinking the water are extremely low, and thus provide a useful input to decision making even with the high levels of uncertainty about many of the input parameters.     

A Comparison of Western Business Instruction in China With U.S. Instruction: A Case Study of Perceived Program Emphases and Satisfaction Levels

This research presents a case study of a joint business degree program between an Association to Advance Collegiate Schools of Business International (AACSB‐I) accredited business school in the United States and a Chinese PhD granting partner university. The case investigates the impact of a U.S.‐based curriculum, taught by U.S. instructors and which uses all English instruction on Chinese student perceptions of program emphases and satisfaction. It compares these perceptions with those of U.S. sister students. The comparison reveals program dissatisfaction among Chinese students when contrasted to U.S. students and for the most part a failure to attend to the program emphases of the West. Reasons for the departures are explored and strategies for improvement are developed.     

Agricultural policy reform in the United States: an unfinished agenda

The 1996 Federal Agriculture Improvement and Reform Act (FAIR) contained important breaks with a tradition of crop–by–crop subsidies dating back to the Agricultural Adjustment Act of 1933. Farmers with recorded base acres were given the opportunity (which nearly all accepted) to sign a seven–year 'contract' with the US Department of Agriculture (USDA), under which payments will be continued on the merged base acres on a declining schedule until the year 2002. FAIR is an unfinished agenda. First, the coverage of 'freedom to farm' is only partial, with numerous commodities left out of the decoupling programme. Second, the largest producers will augment their already significant receipts with generous lump sum transfers from USDA. This will further reinforce the concentration of roughly 90 per cent of receipts and payments in the hands of the 100 000 to 200 000 largest producers of field crops. An alternative would be to make payments in times of low marketing receipts which recede when prices are high.     

Do the GSEs expand the supply of mortgage credit? New evidence of crowd out in the secondary mortgage market

The dramatic government takeover of Fannie Mae and Freddie Mac in September, 2008 was motivated in part by a desire to ensure a continued flow of credit to the mortgage market. This study examines a closely related issue: the extent to which GSE activity crowds out mortgage purchases by private secondary market intermediaries. Evidence of substantial crowd out suggests that government support for the GSEs may be less warranted, whereas the absence of crowd out implies that GSE loan purchases enhance liquidity.Using 1994–2008 HMDA data for conventional, conforming sized loans, three distinct periods with regard to GSE crowd out are apparent. From 1994 to 2003, the share of loans sold to the secondary market increased from 60 to over 90%, private sector and GSE market shares of loan purchases were roughly similar for most market segments, and IV estimates indicate relatively little GSE crowd out of private secondary market purchases. From 2004 to 2006, private loan purchases boomed and dominated those of the GSEs, while IV estimates indicate crowd out jumped to 50% at the peak of the boom. This is especially true in the market for home purchase as opposed to refinance loans. With the crash in housing and mortgage markets in 2007, private sector intermediaries pulled back, the GSEs regained market share, and evidence of GSE crowd out disappeared in both the home purchase loan and refinance markets. These patterns suggest that the degree of GSE crowd out varies with market conditions and that the federal takeover of Fannie Mae and Freddie Mac likely served to enhance liquidity to the mortgage market during the 2007–2009 financial crisis.     

Does advertising increase labour supply? Time series evidence from the UK

Wages in industrialized countries have risen considerably during the last 50 years, whereas hours worked, for manual workers at least, have decreased only marginally. In Europe, one policy response has been to attempt to protect workers from pressure to work long hours by placing legal restrictions on the amount of hours that may be worked each week. This paper examines the possibility that, in fact, observed hours may be the result of a desire of workers to work longer due to a shift in their preferences from leisure to increased consumption, caused by the huge increase in mass media advertising. A cointegrating VAR framework is used to test this hypothesis on UK time series data for both males and females from 1952 to 1997. Advertising is shown to be positively associated with hours worked for both male and female series. Causality tests indicate unidirectional causality, for males and females, from advertising to hours worked. These results suggest that the European policy response is more likely to restrict employee rather than employer discretion over hours.     

Determinants of internal migration in Israel: expected returns and risks

A multinomial logit model of place-to-place migration focusing on economic, geographic and demographic factors is applied to empirical data on inter-regional migration in Israel in 1980. It explains 75% of the (cross-sectional) variance in the data. The results presented in this paper depart from previous empirical work due to its industrialized context and its focus on risk aversion as a determinant of the migration decision. The results support the Harris–Todaro (1970) hypothesis, and indicate that regional similarities in the structure of industrial employment promote migration.
