From the first analysis of immuneprecipitation followed by Western Blotting (WB) Corin and TLP seem to precipitate at the same height ( approximately 50KDa) and are recognized by the same antibodies. In parallel the tests of immunoprecipitation by the use of cell extracts derived from lung cancer cells A549 and NCI-H23 are improved with the aim to be able of obtaining a precipitate containing o...

This paper explores how individual preferences for redistribution depend on future income prospects. In addition to estimating the impact of individuals’ socioeconomic background and of their subjective perceptions of future mobility, we employ panel data to construct dobjectiveT measures of expected gains and losses from redistribution for different categories of individuals. We find that such...

Azotobacter vinelandii strain ATCC 12837 and A. chroococcum strain H23 (CECT 4435) were able to grow on N-free or NH4Cl-amended chemically-defined (Burk's) media, with protocatechuic acid (1-2 mmol 1(-1)) or sodium p-hydroxybenzoate (1-10 mmol 1(-1)) as sole carbon (C) sources. At a concentration of 2 mmol 1(-1), both substrates supported nitrogen fixation (acetylene reduction assay) at similar...

This paper investigates the importance of entrepreneurship when quantifying the aggregate and distributional effects of switching from a progressive to a proportional income tax system. I find that the distributional consequences of the tax reform in a model economy with entrepreneurs contrast markedly from those in a model economy with no entrepreneurs. The elimination of progressive taxation ...

One of Coase’s central insights is that distinguishing between the generator and recipient of an externality is of limited value because externality problems are reciprocal. We reconsider the relevance of the identity of the generator in a model with non-contractible investment ex ante but frictionless bargaining over the externality ex post. In this framework, a party may distort its investmen...

On the Optimality of a Minimum Wage: New Insights from Optimal Tax Theory We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in productivity. The government does not o...

We look at the consequences of allowing public health insurance (PuHI) to be voluntary when its coverage can be supplemented in the market. PuHI redistributes with respect to risk and income, and the market is affected by adverse selection. We argue that making PuHI voluntary does not lead to its collapse since there are always individuals participating in it. Additionally, in some cases, a vol...

In this paper, I analyze consumption, aggregate savings,output and welfare implications of …ve di¤erent social security arragements whenever there is demographic uncertanity. Following Bohn(2002), I analyze the e¤ect of an uncetain population growth in an extended version of a modi…ed Life-cycle model developed by Gertler(1999). Population growth dampens savings and output under all arrangement...

Because of the uncertainties and irreversibilities that are often inherent in environmental degradation, its prevention, and its economic consequences, environmental policy design can involve important problems of timing. I use a simple two-period model to illustrate these optimal timing problems and their implications for environmental policy. I then lay out and solve a continuous-time model o...

This paper analyzes the joint design of fiscal and cap-and-trade instruments in climate policies under uncertainty. Whether the optimal mechanism is a mixed policy (with some firms subject to a tax and others to a cap-and-trade) or a uniform one (with all firms subject to the same instrument) depends on parameters reflecting preferences, production, and, most importantly, the stochastic structu...
