This paper analyses the optimal tax policy and public provision of private goods when individuals di¤er in two respects: income-earning ability and rationality. Publicly provided goods should be overprovided or subsidised, relative to the decentralised optimum, if society’s marginal valuation of them exceeds the individual valuation and if these goods help relax the self-selection constraints, ...

Green incentives are included in the “American Recovery and Reinvestment Act of 2009” (ARRA). It is, however, unclear how these government incentives can be carried out most effectively according to market-based principles and if they can serve as a catalyst for an accelerated green transformation and an ultimate solution to the current U.S. and global economic and financial crisis. The article...

Increasing energy efficiency and reducing the use of hazardous materials are the main goals of Green computing. Energy efficiency has become an important issue in today’s global IT scenario. From embedded systems to large scale systems, all sectors of IT are facing this challenge. The various facts and challenges faced in the Green IT environment are discussed in this paper. This paper also foc...

Measuring specific software quality requirements in a continuous way and at runtime all along the development processes is crucial. Moreover, considering principles of measurement theory, it is still very complex to integrate green metrics in a common standardized and autonomous framework. In our approach, we propose an automated solution based on continuous analysis of SW green measurements, u...

The increasing international mobility of high-skill individuals is often seen as posing a threat to domestic social welfare, by limiting the ability of governments to tax these individuals and redistribute to the poor. In this note, we examine a simple dynamic nonlinear income tax model without commitment. In this setting, it is shown that the threat of emigration by high-skill individuals faci...

European economies are characterized by unionized labor markets and a pronounced governmental redistribution of income. This paper studies a model where those two features are combined with the possibility for individuals to make charitable contributions to the poor. The model exhibits equilibrium unemployment that increases with the degree of altruism. It is shown that a more progressive incom...

The desire to avoid rousing community hostility may encourage firms to behave in an environmentally responsible manner. Firms may engage in corporate social responsibility (CSR) to maintain community support and/or to regain the support of a community where it has been lost. It has been conjectured that such ‘informal regulation’ could effectively replace formal intervention in some settings, a...

We and others have uncovered the existence of human T-cell lymphotropic virus type 3 (HTLV-3). We have now generated an HTLV-3 proviral clone. We established that gag, env, pol, pro, and tax/rex as well as minus-strand mRNAs are present in cells transfected with the HTLV-3 clone. HTLV-3 p24(gag) protein is detected in the cell culture supernatant. Transfection of 293T-long terminal repeat (LTR)...
