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...

We characterize the optimal linear tax on capital in an Overlapping Generations model with two period lived households facing uninsurable idiosyncratic labor income risk. The Ramsey government internalizes the general equilibrium feedback of private precautionary saving. For logarithmic utility our full analytical solution of the Ramsey problem shows that the optimal aggregate saving rate is in...

This paper focuses on how inflation interacts with taxes and interest rates to affect capital formation.1 It uses a simple credit-market framework to explain how inflation magnifies the distorting effects of taxation when the tax treatment of interest income and expense is not fully indexed to inflation.2 The distortion involves a real tax wedge consisting of the difference between the real int...

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...

Tax laws and administrations often treat different sized firms differently. There is, however, little research on the consequences. As modeled here, oligopolists with different efficiencies determine the size distribution of firms. A government that maximizes a weighted sum of consumer surplus, profits and tax receipts can tax firms with different efficiencies differently and provides a referen...

Recent years have witnessed very high and volatile interest rates. This has stirred a debate among analysts as to whether observed interest rates are high by historical standards. Some analysts, focusing on the before-tax real rate, argue that if the observed nominal interest rate is corrected for the effect of expected (or actual) inflation, the ex ante (or ex post) real rate has been very hig...

This paper develops a positive theory of taxation in a federation of states. Its main motivation is to explain two facts about tax schedules in the US. The first one is that states’ income tax rates are relatively low compared to federal income tax rates, in most cases below 5%. The second one is that the overall effective tax schedule at the state level is regressive in every state. The result...

The paper uses both the single rotation and ongoing rotation framework to study the impact of yield tax, lump-sum tax, cash flow tax and tax on interest rate earnings on the privately optimal rotation period when forest value growth is stochastic and forest owners are either risk neutral or risk averse. In the case of risk-neutral forest owner higher yield tax raises the optimal harvesting thre...

Multinational investors often reduce tax on dividends by using indirect investment routes. This paper constructs a tax rate matrix to represent a real-world network of tax treaties between 70 countries and develops network algorithms to study the structure of tax-minimizing (direct or indirect) investment routes in the tax treaty network. The treaty shopping arbitrage rate, defined as the diffe...
