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 ...

We examine the relationship between economic growth, tax policy, and the distribution of capital and labor ownership in a one-sector political-economy model of endogenous growth with productive government spending Þnanced by a proportional tax on capital income. Our analysis shows that inequality in wealth and income can be positively or negatively related to the optimal tax rate. In either env...

In this paper we derive conditions under which optimal tax rates for addictive goods exceed tax rates for non-addictive consumption goods within a rational addiction framework where exogenous government spending cannot be financed with lump sum taxes. We reexamine classic results on optimal commodity taxation and find a rich set of new findings. Two dynamic effects exist. First, households anti...

This paper studies optimum income taxation in a small open economy where households differ with respect to their endowments with wealth. The government raises taxes on income from labor and wealth and a source tax on capital used in domestic production. To avoid taxes, households may, at some cost, shift capital to labor income and vice versa. The government can only observe income after shifti...

This paper models a capital-exporting country that encounters difficulties in taxing foreignsource income, due to tax evasion problems. The paper compares the country’s optimal effective tax rates on the income from capital invested at home and abroad (including penalties levied on detected tax evaders). It finds that tax evasion abroad does not provide a justification for a relatively low effe...

This paper studies the role of family size in the design of optimal income taxation. We consider a second best setting where the government observes the number of children and the income of the parents but not their productivity. With a linear tax schedule the marginal tax rate is shown to decrease with the number of children, while the relationship between the demogrant and family size appears...

We propose an optimal consumption and investment model with asymmetric longterm/short-term tax rates for a small investor. We also consider both the case where an investor can get full tax rebate for capital losses and the case where the investor can only carry over capital losses. The full rebate case is a better model for low income investors while the carry over case is more suited for wealt...

In this research, firms aim at maximizing two purposes of social welfare (environment) and profitability in the supply chain system. It is assumed that there are two supply chains, a green and an ordinary, each consists of a manufacturer and a supplier; in which the manufacturer generates profit through franchises. The green and the ordinary manufacturers form a cartel on the market of a certai...

This paper considers appropriate debt funding strategies for state and municipal governments in the presence of a positive, tax-exempt term premium. The correlation between a measure of income from rate-sensitive assets and the tax-exempt floating rate is the principal focus of the analysis. A single period framework is used to identify the most important information required to design the opti...

The optimal inflation tax is reexamined in the framework of dynamic second best economy populated by individuals with inflation aversion. A simple formula for the optimal inflation rate is derived. Different from the literature, it is shown that if the marginal excess burden of other distorting taxes approaches zero, Friedman’s rule for optimum quantity of money is not optimal, and the optimal ...
