In models with a capital spillover, the market outcome is not Pareto e cient since agents ignore the positive externalities caused by investment. One might conclude that taxes on investment or subsidies to consumption will reduce welfare. However in a model of endogenous growth, either a small tax on capital income, whose proceeds are wasted, increases growth and welfare or a small marginal sub...

This paper presents Genetic Matching, a method of multivariate matching, that uses an evolutionary search algorithm to determine the weight each covariate is given. Both propensity score matching and matching based on Mahalanobis distance are limiting cases of this method. The algorithm makes transparent certain issues that all matching methods must confront. We present simulation studies that ...

Abstract This study compares the protective effectiveness of Social Safety Nets (SSNs) provided by government and NGOs in rural Pakistan, using quasi-experimental methodology on PRPHS (2011–12) data. The treatment group was households receiving SSNs assistance. counterfactual (control group) determined propensity score matching. Outcome indicators were shock-coping strategies from which are the...

We carried our Poisson-Boltzmann (PB) calculations for the effects of charge reversal at five exposed sites (K16E, R119E, K135E, K147E, and R154E) and charge neutralization and proton titration of the H31-D70 semi-buried salt bridge on the stability of T4 lysozyme. Instead of the widely used solvent-exclusion (SE) surface, we used the van der Waals (vdW) surface as the boundary between the prot...

In many organisms, the formation of asparaginyl-tRNA is not done by direct aminoacylation of tRNA(Asn) but by specific tRNA-dependent transamidation of aspartyl-tRNA(Asn). This transamidation pathway involves a nondiscriminating aspartyl-tRNA synthetase (AspRS) that charges both tRNA(Asp) and tRNA(Asn) with aspartic acid. Recently, it has been shown for the first time in an organism (Pseudomona...

We study the long-run effects of Russia’s anti-alcohol campaign, which dramatically altered relative supply hard and light alcohol in late 1980s. find that this policy shifted young men’s preferences from to decades later, we estimate age at consumers form their tastes. show large beer market expansion 1990s had similar on consumers’ tastes, while older tastes remained largely unchanged. then l...

The metastable H 3 1 state in the thorium monoxide (ThO) molecule is highly sensitive to the presence of a CP-violating permanent electric dipole moment of the electron (eEDM) [E. R. Meyer and J. L. Bohn, Phys. Rev. A 78, 010502 (2008)]. The magnetic dipole moment μH and the molecule-fixed electric dipole moment DH of this state are measured in preparation for a search for the eEDM. The small m...

E. coli strain 536 (O6:K15:H31) isolated from a case of acute pyelonephritis, expresses S-fimbrial adhesins, P-related fimbriae, common type I fimbriae, and hemolysins. The respective chromosomally encoded determinants were cloned by constructing a genomic library of this strain. Furthermore, the strain produces the iron uptake substance, enterocheline, damages HeLa cells, and behaves in a seru...

A major problem of the positive theory of income taxation is to explain why statutory income tax schedules in practice are marginal-rate progressive. While it is commonly believed that this is but a simple consequence of the fact that the number of relatively poor voters exceeds that of richer voters in general, putting this contention in a voting equilibrium context is not a trivial task. We d...
