This paper provides a necessary and sufficient condition for the existence of nonautarkic contract in a risk sharing model with two-sided lack of commitment. Verifying the condition takes just one Guassian elimination of a matrix.

This paper considers the effects of corruption and government spending on economic growth. It starts from an endogenous growth model and extends it to account for the detrimental effects of corruption on the potentially productive components of government spending, namely military and investment spending. The resulting model is estimated on a sample of African countries and the results show, fi...

This paper looks at the convergence clubs literature from a Schumpeterian perspective, and it follows the idea that cross-country differences in the ability to innovate and to imitate foreign technologies determine the existence of clustering, polarization and convergence clubs. The study investigates the characteristics of different technology clubs and the growth trajectories that they have f...

A 2-site immunoradiometric assay (IRMA) has been done using Anopheles stephensi fed on Plasmodium vivax blood through parafilm to ascertain at what time in the sporogonic cycle circumsporozoite (CS) antigen can be detected, and to detect CS antigen in mosquitoes squashed on filter paper (FP) and cellulose acetate membrane (CAM). The CS antigen was detectable only in mature oocysts, a day prior ...

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...

Success stories in usable security are rare. In this paper, however, we examine one notable security success: the year-long collaborative investigation of more than two terabytes of leaked documents during the “Panama Papers” project. During this effort, a large, diverse group of globally-distributed journalists met and maintained critical security goals–including protecting the source of the l...

This project developed new results in the topology and foundations of quantum algorithms. It made major developments in the program for topological quantum field computation, including the design of substantially simplified lattice models with topological phases, and new insights into the universality classes of such models. Lattice gas simulations of various classical and quantum systems were ...

In this paper, we derive a nonlinear Picone identity to the pseudo p-Laplace operator, which contains some known Picone identities and removes a condition used in many previous papers. Some applications are given including a Liouville type theorem to the singular pseudo p-Laplace system, a Sturmian comparison principle to the pseudo p-Laplace equation, a new Hardy type inequality with weight an...

Tribulus terrestris is a one-year-old herb dispersed in hot and humid areas in the Mediterranean and warm regions of Europe, Asia, Africa and Australia. This plant has many benefits and is used in traditional medicine for the treatment of various diseases, including kidney stones, low blood pressure, anti-diabetic properties, and treatment of cardiovascular diseases, gastrointestinal disorders,...
