In this paper we examine an alternative policy scenario, where governments allow polluting …rms to trade permits in a strategic environmental policy model. We demonstrate, among other things, that with no market power in the permits market, governments of the exporting …rms do not have an incentive to under-regulate pollution in order to become more competitive. This strategic e¤ect is reversed...

The present paper thoroughly explores second-best efficient allocations in an adverse selection insurance economy. We start from a natural extension of the classical model, assuming less than perfect risk perceptions. We propose first and second welfare theorems, by means of which we describe efficiencyenhancing policies. Notions of weak and strong adverse selection are promising for interpreti...

With worldwide concern over the use of antibiotics in animal agriculture and their contribution to the spread of antibiotic resistance, alternatives to conventional antibiotics are needed. Previous research in our laboratories has shown that colicin E1 is effective against some Escherichia coli strains responsible for postweaning diarrhea (PWD) in vitro. In this study we examined the efficacy o...

F18 fimbrial Esherichia coli strains are associated with porcine postweaning diarrhea and pig edema disease. Recently, the FedF subunit was identified as the adhesin of the F18 fimbriae. In this study, adhesion domains of FedF were further studied by constructing deletions within the fedF gene and expressing FedF proteins with deletions either together with the other F18 fimbrial subunits or as...

OBJECTIVE To evaluate the use of the ML Flow test as an additional, serological, tool for the classification of new leprosy patients. DESIGN In Brazil, Nepal and Nigeria, 2632 leprosy patients were classified by three METHODS : (1) as multibacillary (MB) or paucibacillary (PB) according to the number of skin lesions (WHO classification), (2) by slit skin smear examination, and (3) by serolo...

The use of propensity score methods for program evaluation with non-experimental data typically requires the propensity score be estimated, often with a model whose specification is unknown. While theoretical results suggest that estimators utilizing more flexible propensity score specifications perform better, this has not filtered into applied research. Here, we provide Monte Carlo evidence i...

This review focuses on the diagnostic value of hybrid F18-FDG Positron Emission Tomography/Computerized tomography (PET/CT) in fever of unknown origin (FUO) and inflammation of unknown origin (IUO). Due to the wide range of possible causes both FUO and IUO remain a clinical challenge for both patients and physicians. In addition, the aetiology of IUO shows the same variation in diseases as the ...

This paper sets up a two-sector, two-period trade model of a developing country which is abundant in a non-renewable natural resource but scarce in industrial goods. It shows that lower future travel costs, rising demand for tourism and higher preferences for the environment slow down today’s optimal depletion of the natural resource that can be used for consumption or for exporting tourism ser...
