Both standard and robust methods are used here to estimate models of Engel curves for three household commodities, namely,
food, transport, and tobacco and alcohol in Canada. The income elasticities of demand computed from the various methods differ
significantly for the transport and tobacco-alcohol consumption where there are obvious outliers and zero expenditures problem.
Robust estimators point to lower income elasticities and have better performance than the standard LS and Tobit estimator.
These results are analyzed in the light of the information on finite-sample performance obtained in a previous Monte Carlo
study.

Increasing public concerns about health risks associated with dietary intakes of cholesterol are expected to have significant
impacts on the demand for foods with high fat content. This paper investigates how information about cholesterol, as measured
by two newly constructed indices based on published medical research, has affected the demand for meats (beef, chicken and
pork) and fish in the Nordic countries (Denmark, Finland, Norway and Sweden). To compare the effects of information across
countries and over time, the demand equations for all the countries are estimated within one system, and a complete set of
price and expenditure elasticities is estimated. Our findings suggest that health information has affected consumption in
a healthy way in all countries studied except for Denmark. We find positive effects on the demand for chicken in Finland,
Norway and Sweden and for fish in Finland and Sweden. A negative effect on the demand for beef in Sweden also is found.

Summary. Recent work by Bossert, Pattanaik and Xu provides axiomatic characterizations of some decision rules for individual decision
making under complete uncertainty. This note shows that, in the case of two of these rules, they do not satisfy one of the
axioms used for their characterization. A counterexample illustrating this fact is provided, as well as an alternative way
to characterize the two rules under consideration, mantaining as far as possible the original axioms proposed by Bossert,
Pattanaik and Xu.

This paper examines the determinants of the EPAs litigation strategy between 1977 and 1996 focusing on the tenure of Ann Gorsuch. Two hypotheses about this period are tested: (1) that changes in the EPAs litigation strategy were in fact an effort to reduce the expected penalty for violating environmental laws or (2) that the changes made in litigation strategy were consistent with efforts to reduce transaction cost. Contrary to previous research, I find no conclusive evidence of an overall shift toward business interests in EPA prosecutions. There is, however, clear evidence of shifts in the EPAs litigation strategy across administrations. 相似文献
