Church, State, and Moral Values: The Limits of American Pluralism
This thesis aims to help sailboat owners to decide a preferable NACA profile. A CFD comparison in terms of drag and lift coefficients between two NACA profiles have been applied on a typical fin keel. Each profile has been computed with different angles of attack to investigate the impact of small direction changes. ANSYS Fluent 13.0 is used to model the flow according to RANS k-epsilon model. The conclusion is that NACA65 series gives lower drag while NACA64 series gives higher lift.Syftet med det här examensarbetet är att undersöka skillnaderna för olika NACA-kölprofiler med avseende på tryckkoefficienter Arbetet strävar även efter att ge båtägare en tydligare bild av en fördelaktig NACA-profil. Varje kölprofil har beräknats med olika anfallsvinklar för att undersöka effekten av små vinkeländringar. ANSYS Fluent 13.0 har använts för att modellera flödet enligt k-epsilon-modellen. Slutsatsen är NACA65-serien ger en lägre motståndskoefficient medan NACA64-serien ger en högre lyftkoefficient
Optimal Taxation of Human Capital and theEarnings Function
This paper explores how the specification of the earnings function impacts the optimal tax treatment of human capital. If education is complementary to labor effort, education should be subsidized to offset tax distortions on labor supply. However, if most of the education is enjoyed by high ability households, education should be taxed in order to redistribute resources to the poor. The paper identifies the exact conditions under which these two effects cancel and education should be neither taxed nor subsidized. In particular, with non-linear tax instruments, education should be weakly separable from labor and ability in the earnings function. With linear taxes, education should also feature a constant elasticity in a weakly separable earnings function.optimal linear and non-linear taxation, optimal education subsidies, human capital, earnings function
Structural Distortions and Decentralized Fiscal Policies in EMU
The combination of discretionary monetary policy, labor-market distortions and nominal wage rigidity yields an inflation bias as monetary policy tries to exploit nominal wage contracts to address labour-market distortions Although an inflation target eliminates this inflation bias, it creates a conflict between monetary policy and discretionary fiscal policy if fiscal policy is set at a higher frequency than nominal wages are. To avoid the associated excessive accumulation of public debt, ceilings on public debt are called for. If countries differ substantially in terms of structural distortions or economic shocks, uniform debt ceilings must be complemented by country-specific debt targets in order to prevent decentralised fiscal authorities from employing debt policy strategically.Discretionary monetary policy, wage rigidity, decentralized fiscal policy, monetary union, inflation targets, debt targets
Ageing, Funded Pensions and the Dutch Economy
This paper attempts to paint a coherent picture of the effects of ageing on a small, open, economy with large pension funds in different institutional settings. Quantitative scenarios are projected with an applied computable general equilibrium model with institutional details. We find that ageing leads to a tighter labor market, increasing costs for both pension funds and the government, and leaving the economy vulnerable to financial and further demographic shocks. We show that defined benefit pension arrangements can be destabilizing, but less so if an average-wage variable-indexation contract is chosen. Government can help by adopting a policy of tax smoothing, but the single most important determinant of the net burden of ageing is the eventual size of the increase in labor market participation of older workers. The intergenerational welfare effects of demographic shocks and changes in international interest rates are sizable and should be an integral part of the assessment of different policy instruments.ageing, funded pensions, applied general equilibrium models, the Netherlands
Financing Retirement in the European Union
This paper explores how EU countries can address various challenges (including the aging of the population) affecting their systems of old-age income support. It presents two scenarios illustrating the most important uncertainties surrounding the major developments that affect the pension systems of the EU. To diversify these risks, EU governments should act on several fronts. In addition to the formation of human capital (especially that of children), employment (especially that of older workers) should be boosted. This calls for social insurance reform with more emphasis on individual saving schemes. Pension schemes should be more explicit about how they share demographic and other risks. Countries that currently rely heavily on public pay-as-you-go (PAYG) schemes should stimulate private pensions by gradually reducing PAYG benefits collected by high-income earners, by issuing new financial instruments, and by conducting intergenerational risk sharing through the tax system.
FUNDAMENTAL TAX REFORM IN THE NETHERLANDS
The Dutch Parliament has passed legislation for a new income tax that abolishes the current tax on personal capital income and substitutes it by a presumptive capital income tax, which is in fact a net wealth tax. This paper contrasts this wealth tax with a conventional realization-based capital gains tax, a retrospective capital gains tax which attempts to charge interest on the deferred tax, and a capital accretion tax which taxes capital gains as they accrue. None of the approaches meets all criteria for a ''good'' income tax, i.e., equity, efficiency, and administrative feasibility. We thus conclude that the effective and neutral taxation of capital income can best be ensured through a combination of (a) a capital accretion tax to capture the returns on easy-to-value financial products, (b) a capital gains tax with interest to tax the returns on hard-to-value real estate and small businesses, and (c) a broad presumptive capital income tax, i.e., a net wealth tax, to account for the utility of holding wealth. We favor uniform and moderate proportional tax rates in the context of a dual income tax under which capital income is taxed separately from labor income.public economics ;
Pension Sytems and the Allocation of Macroeconomic Risk
This paper explores the optimal risk sharing arrangement between generations in an overlapping generations model with endogenous growth. We allow for nonseparable preferences, paying particular attention to the risk aversion of the old as well as overall ``life-cycle´´ risk aversion. We provide a fairly tractable model, which can serve as a starting point to explore these issues in models with a larger number of periods of life, and show how it can be solved. We provide a general risk sharing condition, and discuss its implications. We explore the properties of the model quantitatively. Among the key findings are the following. First and for reasonable parameters, the old typically bear a larger burden of the risk in productivity surprises, if old-age risk-aversion is smaller than life risk aversion, and vice versa. Thus, it is not necessarily the case that the young ensure smooth consumption of the old. Second, consumption of the young and the old always move in the same direction, even for population growth shocks. This result is in contrast to the result of a fully-funded decentralized system without risk-sharing between generations. Third, persistent increases in longevity will lead to lower total consumption of the old (and thus certainly lower per-period consumption of the old) as well as the young as well as higher work effort of the young. The additional resources are instead used to increase growth and future output, resulting in higher consumption of future generations.Social optimum, pension systems, risk sharing, overlapping generations
Rhineland Exit?
We argue in favor of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle about the ultimate goal of the company. Second, giving workers a claim on the surplus of the firm raises the cost of capital for investments in jobs. Third, making shareholders the ultimate owner of the firm provides the best possible diversification of firm-specific risks. Diversification of firm-specific risk on capital markets is an efficient form of social insurance. Hence, firms should bear the full cost of specific investment, while workers should be paid only their outside option. Empirical results for Denmark, Portugal and the United States show that Denmark is closest to the first-best outcome, while Portugal and the United States deviate in different ways. Coordination in wage bargaining and collective norms help reduce the claim of workers on the firm’s surplus. Collective action, however, is a mixed blessing because politicians also face the temptation to please incumbent workers with short-run gains at the expense of exposing workers to firm-specific risks and reducing job creation. The transition from the Rhineland towards the shareholder model is fraught with difficulties. While society reaps long-run gains in efficiency, in the short run a generation of insiders has to give up their rights.wage setting, optimal risk sharing, employment protection, corporate governance
