We look at the theory of arbitrage with taxation under certainty. The tax scale in our model is not linear. Under the … premise that tax scale is convex, we analyze prices that do not exhibit arbitrage opportunities. It turns out that there are … portfolio is bounded from above and cannot increase infinitely. In a model with a linear tax scale such a bounded arbitrage …

This paper, intended for researchers, introduces a stochastic method for calculating the optimal tax schedule based on … tax calculation introduced by J.A. Mirrlees. A genetic algorithm is applied instead of the numerical or analytical method … attitude to work and budget external flows on the income tax schedule. Then, we measured the convergence of the search process …

(social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic … income and a tax defined by a 4th degree polynomial. The rule is applied to total taxable household income. A … to identify – within the class defined above – the tax-transfer rule that maximizes a social welfare function.We present …

towards universality, unconditionality and simplicity. Our main research question is whether tax-transfer rules designed …. We adopt a computational approach to the design of optimal tax-transfer rules, within a flexible class. The exercise is … the countries. The optimal tax-transfer rules feature a universal unconditional basic income or, equivalently, a negative …
