Optimal unemployment insurance and redistribution

We characterize optimal income taxation and unemployment insurance in a search-matching framework where both voluntary and involuntary unemployment are endogenous and Nash bargaining determines wages. Individuals differ in utility when voluntarily unemployed (non-participants in the labour market) and decide whether to participate as a job seeker and if so, how much search effort to exert. Unemployment insurance trades off insurance versus moral hazard due to search. We show that it is optimal to have a positive linear wage tax without any redistributive concerns even if search is efficient so the Hosios condition is satisfied. We also allow for different productivity types so there is a redistributive role for the income tax and show that a proportional wage tax internalizes the macro effects arising from endogenous wages. Lump-sum income taxes and transfers can then redistribute between individuals of differing skills and employment states. Our analysis embeds optimal unemployment insurance into an extensive-margin optimal redistribution framework where transfers to the involuntary and voluntary unemployed can differ, and nests several standard models in the literature

Cash-flow business taxation revisited: Bankruptcy, risk aversion and asymmetric information

It is well-known that cash-flow business taxes with full loss-offset, and their present-value equivalents, are neutral with respect to firms' investment decisions when firms are riskneutral and there are no distortions. We study the effects of cash-flow business taxation when there is bankruptcy risk, when firms are risk-averse, and when financial intermediaries face asymmetric information problems in financing heterogeneous firms. Cash-flow taxes remain neutral under bankruptcy risk alone, but can distort the entry and investment decisions of firms under both risk-aversion and asymmetric information. We characterize the nature of such distortions and show that cash-flow taxes can increase social welfare in this context. An ACE tax is equivalent to a cash-flow tax but is easier to implement under asymmetric information

"Fiscal Equalization in Japan: Assessment and Recommendations"

Intergovernmental fiscal relations in Japan have been strained in recent years. This paper seeks to assess the Japanese equalization transfer in the light of the theory of fiscal federalism. This paper argues that the case for equalization lies in offsetting net fiscal benefit (NFB) differentials across jurisdictions. It has been shown that the case for equalization and its design depend on the type of public good being provided as well as the mode of finance. Moreover, where equalization is called for, its form and level can be very different depending on whether the relevant policy goal is that of fiscal equity or fiscal efficiency. Studying the institutional context, we arrive at the conclusion that the system of equalization transfers in Japan is consistent with the application of those principles.

Designing a basic income guarantee for Canada

We propose mechanism for implementing a two-stage harmonized Basic Income Guarantee with federal and provincial components. In Stage One, the federal government replaces its refundable and nonrefundable tax credits with an income-tested basic income delivered through the income tax system. The reform is revenue-neutral. In Stage Two, each province decides whether to implement a provincial basic income guarantee that is harmonized with the federal one but allows province-specific basic income levels. The provincial basic income replaces provincial refundable and nonrefundable tax credits as well as welfare and disability transfers, and is also revenue-neutral. All social services and contributory social insurance programs remain intact. An illustrative calculation using Statistical Canada's SPSD/M model shows the financial feasibility of a national BIG of $20,000 per adult adjusted for family size with a benefit reduction rate of 30%

Allowance for Shareholder Equity - Implementing a Neutral Corporate Income Tax in the European Union

This paper proposes the introduction of a consumption-based corporate income tax in the European Union. Our proposal would guarantee neutrality regarding investment decisions and at the same time increase cost-efficiency. The proposal is based on the S-base cash flow tax, where transactions within the corporate sector are not at all taxable and only transactions be-tween shareholders and corporations are subject to tax. In contrast to existing S-base cash flow tax systems, tax deductibility of investments is deferred. Rather, the acquisition costs and capital endowments are compounded at the capital market rate and are set off against fu-ture capital gains. Dividends and withdrawals are fully taxable at the shareholder level. Be-cause of the similarities to the Allowance for Corporate Equity (ACE) tax our proposal is called Allowance for Shareholder Equity (ASE tax). The ASE tax exhibits the same neutrality properties as the traditional cash flow tax. More-over, the compounded inter-temporal credit method ensures that it is neutral with respect to the decision between domestic and foreign investment. To increase acceptance of the ASE tax, current taxpayers' documentation requirements will be reduced rather than extended. Our proposal is shaped in a way that it could be realized in a single EU country or in all member states of the EU
