the effect of drought on the seed yield and some associated characteristics of common been under normal and drought stress conditions and determination of durable genotypes to drought were studied by planting 32 genotypes in two separate augmented designs in normal and stress conditions. these genotypes were evaluated in randomized complete block design with 3 replications in the field of facul...

Aetna considers vagus nerve electrical stimulators medically necessary durable medical equipment (DME) for shortening the duration or reducing the severity of seizures in members with partial onset seizures who remain refractory to optimal anti-epileptic medications and/or surgical intervention, or who have debilitating side effects from anti-epileptic medications. (Note: Electronic analysis of...

This paper studies an incompletely informed regulator's problem of inducing a firm producing durable pollution to adopt a socially optimal pollution storage technology. We construct a sparse, yet flexible, theoretical model that can be applied directly to concrete situations as it is stated explicitly in terms of statistical parameters. Next, we show the existence of an optimal regulatory contr...

We consider an overlapping generations model with a Durable Local Public Good (DLPG). We establish a Tiebout Theorem (equilibrium exists and is first best) as well as a Second Welfare Theorem in this dynamic DLPG economy. We define conditions under which local provision of durable public goods results in the full internalization of the intergenerational spillovers that durability entails. In co...

We present a model of the market for a used durable in which agents face ...xed costs of adjustment, the magnitude of which depends on the degree of adverse selection in the secondary market. We ...nd that, unlike typical models, the sS bands in our model contract as the variance of the shock process increases. We also analyze a dynamic version of the model in which agents are allowed to make d...

Sustained ventricular tachycardia (VT) in patients with advanced cardiomyopathy is a potentially life-threatening arrhythmia. Newer treatment strategies have evolved that combine the use of catheter ablation to target the substrate for VT and ventricular assist devices (VADs) to hemodynamically support the failing ventricle. This editorial is targeted to the practicing clinician caring for thes...

Do active secondary markets aid or harm durable goods manufacturers? We build a dynamic equilibrium model of durable goods oligopoly, with consumers who incur lumpy costs when transacting in the secondary market, and calibrate it to U.S. automobile industry data. By varying transaction costs, we obtain a direct measure of the competitive pressure that secondary markets create on durable goods m...
