The tax-2 and tax-4 genes of C. elegans encode two subunits of a cyclic nucleotide-gated channel that is required for chemosensation, thermosensation and normal axon outgrowth of some sensory neurons. Here we show that, in tax-2 and tax-4 mutants, young larvae have superficially normal axons, but axon outgrowth resumes in inappropriate regions in late larval stages. Using a temperature-sensitiv...

How Tax Progression Affects Effort and Employment Within an efficiency wage framework, we study the effects of two revenue-neutral tax reforms that change the progressivity of the labour tax system. A revenue-neutral increase in both the wage tax and tax exemption and a revenue-neutral change in the composition of labour taxation towards the tax with the smaller tax base will lead to the same r...

The explosion of globalization has increased firms incentives to exploit international tax differentials to their benefit. In this paper we consider a simple world with two countries with different market sizes and two multinationals with a division in each country. Both countries use a source-based profit tax on multinationals, who compete a la Cournot in each local market and use profit shift...

This paper analyzes a two-country model with an international investor considering acquisitions of already existing target firms in a high-tax country and a low-tax country. The investor is able to shift profits from one location to another for tax saving purposes. Two systems of corporate taxation are compared, a system with separate accounting and a system with tax base consolidation and form...

Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority's power. Descriptions of the tax authority's power may affe...

AIM To examine patterns of tax burdens produced by specific, ad valorem, and various types of combination taxations. METHOD One hundred unique hypothetical alcoholic beverages were mathematically simulated based on the amount of ethanol and perceived-qualities contained. Second, beverages were assigned values of various costs and tax rates, and third, patterns of tax burden were assessed per ...

a r t i c l e i n f o Tax systems often discriminate among the various organizational forms of doing business and may therefore affect the choice of organizational form. This paper studies how special tax regimes shape the organizational form choice. Although the full effects depend on the way that firm-level special tax regimes are designed, special regimes generally tend to favor pass-through...

Tax evasion is modeled as a risky activity and integrated into a standard problem of optimal tax design. It is shown that there is a trade off between reducing tax evasion and reducing tax distortion. Thus it is efficient to supplement a broad-based wage tax by a tax on specific consumption if the former is evaded and the latter not. The optimal tax structure can be characterized by an explicit...

An income tax is equivalent to a uniform tax on all expenditures, including expenditures on commodity tax payments. This will compound the tax being applied to any taxed commodity. In the presence of an income tax, therefore, any expenditure tax (including a pollution tax) will produce a higher effective tax than its nominal tax rate would suggest. For example, a nominal Pigouvian tax applied t...

The notion that taxes should be simpler is one of the very few propositions in tax policy that generates almost universal agreement. The fundamental paradox of tax simplification is that despite this consensus, almost every year tax rules become more complex. This report, based on recent congressional testimony, examines a broad range of issues regarding tax complexity. Section II discusses the...
