The standard profit function approach has been applied successfully in a number of LDCs to measure the price responsiveness of peasant farmers. Yet, various problems afflict this approach including, but not restricted to, the existence of non‐competitive market structures, zero‐valued observations, exclusion of relevant variables, lack of participation in output and/or input markets, and endogeneity of input and/or output prices. The impact of these problems on estimation results, however, can be minimised through modifications and adaptations of the standard approach, better specification of the underlying technology, and the use of selected functional forms. 相似文献

The duty-of-care requirement cannot be used anymore as the touchstone to differentiate negligence from strict liability because
it can be found in many forms of the latter. Duty of care is smuggled into strict liability hidden under the scope of liability
requirement (traditionally called “proximate causation”). As far as the scope of liability requirement is common to negligence
and to many forms of strict liability, there is a fairly large common ground to both liability rules, and consequently the
marginal Hand formula is applied to both rules. Indeed, under a negligence rule, the marginal Hand formula is applied twice:
first to assess whether or not the defendant did breach his or her duty of care, and, second, to delimit whether or not the
defendant’s behavior was a proximate cause of the harm suffered by the victim. However, under a strict liability rule, the
Hand formula is applied only once when the proximate causation question is raised. Traditional law and economics analysis
has almost always taken the normative question raised by the causation requirement as given, which is a potential major problem
due to the importance of scope of liability or proximate causation in legal practice. Defining the scope of liability, that
is to say, the boundaries of the pool of potential defendants, is the basic legal policy decision for each and every liability
rule. In the normative model presented in this paper, the government first chooses efficient scope of liability, and given
the scope of liability, the government then decides the liability rule and damages that guarantee efficient precaution. In
the article, most known scope of liability rationales developed by both common law and civil law systems are discussed in
order to show the substantial common ground between negligence and strict liability. 相似文献

We compared clinical syndromes, expressed concerns, and personality styles of adolescent inpatients with substance use disorders (SUD; n=44) vs. without substance use disorders (non-SUD; n=61) using the Millon Adolescent Clinical Inventory. The two groups did not differ with regard to age, sex, ethnicity, functional severity, or the frequency of other major psychiatric disorders, and were drawn from the same overall sample population. SUD subjects showed significantly higher levels of delinquent predisposition and lower levels of anxiety. Consistent with these syndromal findings, we found that SUD subjects were characterized by higher levels of unruliness and social insensitivity and lower levels of submissiveness. Our findings suggest that, in severely disturbed adolescents who require psychiatric hospitalization, externalizing phenomena are closely associated with SUD. Our findings also suggest that internalizing problems also exist in SUD, although not at levels greater than that observed in non-SUD inpatients.Received Ph.D. in clinical psychology from the University of Pittsburgh.

A large literature has studied the trend of greaterpolarization between Democrats and Republicans in Congress.This paper empirically examines the extent to which inflationand unemployment explain cyclical movements ofpolarization over time. An informal application of thestandard Downsian spatial competition model of partiesgenerates the following relationships, ceteris paribus: (1)inflation should be associated with policy convergence, (2)unemployment should be associated with polarization, (3) theeffect of unemployment on polarization should be larger inmagnitude than the effect of inflation on convergence, and (4)the effect of unemployment on polarization should be strongerin the House than in the Senate. We estimate the relationshipbetween vote records and business cycle conditions over the1947–1999 period using a GLS model with varying lags. Ourresults are broadly consistent with these business cyclehypotheses of polarization, though greater support is found inHouse data than in Senate data. 相似文献
