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...

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...
