Toxoplasmosis is a zoonosis caused by the protozoan Toxoplasma gondii, and it is found worldwide. To determine whether ungulates are reservoirs of T. gondii in an isolated and remote region of the northeastern Peruvian Amazon, antibodies to T. gondii were determined in 5 species of ungulates by the modified agglutination test (MAT). These animals were hunted by subsistence hunters along the Yav...

Since it has been shown that completeness and constructiveness is an unattainable goal for paretian and anonymous social welfare relations on infinite utility streams, recent contributions generally propose criteria displaying some incomparability. I suggest an interpretation of incomparability which sets a limit to the recourse to the judgment of incomparability when certain intergenerational ...

We examine seller strategies in 1177 Internet auctions on eBay, to understand the diversity of strategies used, and their impacts. Dimensions of strategic choice include the use of a ‘Buy it Now’ option, the level of the starting price, and the use of a secret reserve price. A major focus of our analysis is on differences across sellers with different volumes of sales. The largest volume seller...

Amino acid modifications of the Thermobifida fusca Cel9A-68 catalytic domain or carbohydrate binding module 3c (CBM3c) were combined to create enzymes with changed amino acids in both domains. Bacterial crystalline cellulose (BC) and swollen cellulose (SWC) assays of the expressed and purified enzymes showed that three combinations resulted in 150% and 200% increased activity, respectively, and...

The first electronic Economics preprint appeared in 1993. Since then the growth has been dramatic as the use of the World Wide Web has exploded. RePEc has been instrumental in facilitating access to Economics preprints and in bringing order to the chaos that the WWW frequently represents. In a related effort S-WoPEc provides user friendly tools for adding data to the RePEc system. While this is...

This paper examines the impact of transaction costs on economic welfare and development. We extend the static model of Romer (1994), in which transaction costs reduce welfare by the reducing the equilibrium number of intermediate goods, and estimate the welfare losses in the case of domestic transaction costs. The main analysis of the paper extends a dynamic model of Ciccone and Matsuyama (1996...

In the aftermath of the 2008 global financial crisis, the implications of financial liberalisation for stability and economic growth has come under increased scrutiny. One strand of literature posits a positive relationship between financial liberalisation and economic growth and development. However, others emphasise the link between financial liberalisation is intrinsically associated with fi...

We conduct two experiements of the claim that people are overconfident. We develop new tests of overplacement which are based on a formal Bayesian model. Our two experiments, on easy quizzes, find overplacement. More precisely, we find apparently overconfident data that cannot be accounted for by a rational population of expected utility maximizers with a good understanding of the nature of the...
