Growing inequality in the developed world has led to calls for increasing countries’ top marginal tax rates. Crucially, the optimal top marginal income tax rate depends on people’s tendency to migrate in response to changes in the tax rate. Changes in tax rates and and tax policy must take into account that increases in income tax rates may compel people to leave a country or state. This paper ...

Laffer curve indicates relationship between tax rate and tax income. The aim of this paper is estimating of laffer curve in Iranian economy. To do so, we have used threshold regression method. Empirical results indicate that since the tax rate is low (the threshold value is less than 0.0848) in two-regime model, tax rate and tax income have a significant positive relationship, but when the tax ...

This paper presents an analysis of the extent to which tax planning affects the level of the inheritance tax rate that is perceived to be fair. In a factorial survey conducted in Germany, tax planning was found to increase the fair tax rate by approximately 4 percentage points. The fair tax rate is determined by not only the size of the bequest, the relationship of the heir to the bequeather, a...

This paper studies the effects of effluent taxes on firms’ allocation of resources to cost-reducing and emission-reducing R&D, and on entrepreneurs’ decisions to develop new goods and enter the market. A tax set at an exogenous rate that does not depend on the state of technology reduces growth, the level of consumption of each good, and raises the number of firms. The induced increase in the v...

abstract in this paper, markov chain and dynamic programming were used to represent a suitable pattern for tax relief and tax evasion decrease based on tax earnings in iran from 2005 to 2009. results, by applying this model, showed that tax evasion were 6714 billion rials**. with 4% relief to tax payers and by calculating present value of the received tax, it was reduced to 3108 billion rials. ...

In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate fluctuations. The main result of the paper is that price stability appears to be a central goal of optimal monet...

I derive the optimal timing strategy for an investor taking tax gains and losses on tax-exempt bonds (up to a 7% gain over buy-and-hold). I then derive the issuer’s optimal coupon rate, which maximizes the tax benefit for a tax-timing investor (up to a 3.5% gain over issuing at par, potentially more than the cost of issuance itself). All these gains are transfers from the U.S. Treasury to local...

This paper studies the e ects of agent heterogeneity on optimal capital income tax rates. In a two period model with arbitrarily many heterogeneous agents, we explicitly derive the welfare e ects of taxation depending on the distribution of the agents' characteristics. In particular, we show that the sign of the optimal capital income tax rate depends not on the extent of inequality in goods en...
