When parallel applications are run in large-scale distributed environments, such as grids, peer-to-peer (P2P) systems, and clouds, the set of resources used can change dynamically as machines crash, reservations end, and new resources become available. It is vital for applications to respond to these changes. Therefore, it is necessary to keep track of the available resources—a problem which is...

The Redistributive Effects of Tax Benefit Systems in the Enlarged EU How do different components of the tax and transfer systems affect disposable income inequality? This paper explores the redistributive effects of different tax benefit instruments in the enlarged EU based on two approaches. Inequality analysis based on the standard approach suggests that benefits are the most important factor...

The extant literature on fat taxes and thin subsidies tends to focus on the overall e ectiveness of such scal instruments in altering diets and improving health. However, little is known about the welfare impacts of scal food policies on society. This paper lls a gap in the literature by assessing the distributional impacts and welfare e ects resulting from a tax-subsidy combination on di erent...

In this paper we analyze the implications of demographic shift for an economy’s fiscal sustainability through lens of fiscal space. We formulate a stochastic dynamic general equilibrium, overlapping generations model to measure fiscal space in terms of budgetary room between the current and maximum tax revenues (the peaks of Laffer curves). We calibrate the model to Japan and US data and conduc...

There is policy interest in using tax to change food purchasing behaviour. The literature has not accounted for the oligopolistic structure of the industry. In oligopoly the impact of taxes depend on preferences, and how firms pass tax onto prices. We consider a tax on saturated fat. Using transaction level data we find that the form of tax and firms’ strategic behaviour are important determina...

This paper describes the positive effect that corporate income tax has on capital formation in the presence of liquidity constraints and uninsurable risk. The author uses a dynamic generalequilibrium model in which individuals choose whether to become entrepreneurs or workers. Workers save by holding corporate equity and therefore are subject to double taxation, as the return on their savings i...
