From FPGA to ASIC: A RISC-V processor experience

This work document a correct design flow using these tools in the Lagarto RISC- V Processor and the RTL design considerations that must be taken into account, to move from a design for FPGA to design for ASIC

The Tax Subsidy to Employment-Based Health Insurance and the Distribution of Well-Being

Pauly considers some recent contrasting views on the distributional effects of the tax subsidy within employment groups. He shows that the correct answer depends on what one assumes to be the within-group incidence of the reduction in money wages that occurs when group insurance is part of a competitive compensation package

Social Security Reform with Uninsurable Income Risk and Endogenous Borrowing Constraints

We study the aggregate effects of a social security reform in a large overlapping generations model where markets are incomplete and households face uninsurable idiosyncratic income shocks. We depart from the previous literature by assuming that, because of lack of commitment in the credit market, the borrowing constraint in the unique asset is endogenously determined by the agents' incentives to default on previous debts. We find that a model with exogenous borrowing constraints overestimates the positive e¤ect of reforming social security on the capital stock and the saving rate, compared to our model with endogenous borrowing limit. The reason is that, in the latter, the size of precautionary savings is smaller because after the reform the incentives to default on previous debts are lower and consequently households face more relaxed borrowing limits. Adding retirement accounts to the basic model does not change these conclusions, although the quantitative importance of endogenizing borrowing constraints is reduced.Social Security, Borrowing Constraints, Incomplete Marrkets, Income Risk

Null Surfaces and Legendre Submanifolds

It is shown that the main variable Z of the Null Surface Formulation of GR is the generating function of a constrained Lagrange submanifold that lives on the energy surface H=0 and that its level surfaces Z=const. are Legendre submanifolds on that energy surface. The behaviour of the variable Z at the caustic points is analysed and a genralization of this variable is discussed.Comment: 28 pages, 7 figure
