Data envelopment analysis (DEA) is among the most popular empirical tools for measuring cost and productive efficiency. Because DEA is a linear programming technique, establishing formal statistical properties for outcomes is difficult. We show that the incidence of inefficiency within a...

Idiopathic Intracranial Hypertension (IIH; pseudotumor cerebri) is a disorder with a reported incidence rate of one to three per 100,000 people in the general population. The rate among obese females of childbearing age is approximately 20 out of every 100,000 (1,9,17,25). As its name suggests,...

Conceptual modeling and empirical analysis of individuals’ sequential self-selection of adherence to voluntary treatment or education programs is an ongoing and unsettled area of inquiry. Both the representation of the decision process and the implementation of econometric methods for...

When a binary dependant variable is misclassified probit and logit estimates are biased and inconsistent. In this paper we suggest a conceptual basis for endogenous misclassification of the dependant variable due to systematic respondent bias and the use of Likert scales commonly used in...

In four Southern African countries where the HIV prevalence rate is among the highest in the world, 46% of female and 68% of male adolescents infected with HIV report having never engaged in sex. This finding indicates either the dominance of non-sexual modes of HIV transmission or systematic...

This paper studies how the change from retrospective cost-based reimbursement to a prospective payment system shifted hospital investment strategies from quality-enhancing technologies to cost-saving technologies. A consequence of this change was the opportunity for for-profit hospitals to...

We consider a situation where treatment outcome is observed after two stages of selection; first of participation into the treatment, then in completion of the treatment. Estimates were obtained using two methods. First, three different binary response selection models were estimated...

We analyze the decision to participate in community-based universal prevention programs through the framework of prospect theory, with family functionality, and related risk status, providing the reference point. We find that participation probability depends on the relative ratios of the...

The goals of the present paper were to assess measurement invariance using a common econometric method and to illustrate the approach with self-reported measures of parenting behaviors before and after a family intervention. Most recent literature on measurement invariance (MI) in psychological...

We examine how personality relates to self-reported health satisfaction. With a nation-wide dataset from the United Kingdom, we provide evidence that personality influences how individuals report their satisfaction with their overall health. Using the classification of personality traits...
