Merger Policy to Promote Global Players? A Simple Model

We use a simple framework where firms in two countries serve their respective domestic markets and a world market to analyze under which conditions cost-reducing mergers will be beneficial for the merging firms, the home country, and the world as a whole. For a national merger, the policies enacted by a national merger authority tend to be overly restrictive from a global efficiency perspective. In contrast, all international mergers that benefit the merging firms will be cleared by either a national or a regional regulator, and this laissez-faire approach is also globally efficient. Finally, we derive the properties of the endogenous merger equilibrium

The Taxation of Interest in Europe: A Minimum Withholding Tax?

This paper provides an analysis of the proposal for introducing a minimum withholding tax on interest in the EU. We present a model with three countries: a typical EU country, an 'inside' tax haven, and an 'outside' tax haven. In the initial non-cooperative solution, the former two countries impose withholding taxes on interest. We investigate what happens to welfare in these countries, if the 'inside' tax haven is forced to raise its withholding tax. From the model we proceed to a broader evaluation of the minimum withholding tax proposal.

Taxes and Venture Capital Support

In this paper we set up a model of start-up finance under double moral hazard. Entrepreneurs lack own resources and business experience to develop their ideas. Venture capitalists can provide start-up finance and commercial support. The effort put forth by either agent contributes to the firm’s success, but is not verifiable. As a result, the market equilibrium is biased towards ine.ciently low venture capital support. The capital gains tax becomes especially harmful, as it further impairs advice and causes a first-order welfare loss. Once the capital gains tax is in place, limitations on loss offset may paradoxically contribute to higher quality of venture capital finance and welfare. Subsidies to physical investment in VC-backed startups are detrimental in our framework.venture capital, capital gains taxation, double moral hazard

Public Policy for Start-up Entrepreneurship with Venture Capital and Bank Finance

This paper proposes and analyses a model of start-up investment. Innovative entrepreneurs are commercially inexperienced and can benefit from venture capital support. Only part of them succeed in matching with a venture capitalist while the rest must resort to standard bank finance. We consider a number of policies to promote entrepreneurship and venture capital backed innovation.venture capital bank finance, matching, moral hazard, public policy

The Political Economy of Capital Income and Profit Taxation in a Small Open Economy.

This paper considers the political economy of the mix of profit, investment and saving taxation in a small open economy where agents generally differ in their shares of profit and other income. In this setting, capital income taxation can have the dual role of financing government spending and of redistributing income. With majority voting, the paper can explain why distorting saving taxation exists, even if profits are not taxed to the fullest extent. Alternatively, saving may be subsidized, even if profit and investment are highly taxed. This paper further examines the role of the foreign ownership of domestic firms in explaining capital income taxation.

Start-ups, Venture Capitalists, and the Capital Gains Tax

A model of start-up finance with double moral hazard is proposed. Entrepreneurs have ideas but lack own resources as well as commercial experience. Venture capitalists provide start-up finance and managerial support. Both types of agents thus jointly contribute to the firm’s success, but neither type’s effort is verifiable. We find that the market equilibrium is biased towards inefficiently low venture capital support. In this situation, the capital gains tax is particularly harmful. The introduction of a small tax impairs managerial advice and leads to first order welfare losses. Once the tax is in place, limitations on loss off-set may paradoxically contribute to higher quality of venture capital backed entrepreneurship and welfare.venture capital, capital gains taxation, double moral hazard.

Self-Selection and Advice in Venture Capital Finance

In financing start-up firms, venture capitalists carefully select among alternative projects, design incentive compatible financial contracts and support portfolio companies with value enhancing managerial advice. This paper considers how venture capitalists can induce self-selection among entrepreneurial firms with different qualities by designing appropriate contracts and offering commercial support. We study the efficiency of the competitive market equilibrium with respect to the level and quality of entrepreneurship and the level of effort by entrepreneurs and venture capitalists. We also provide comparative statics results with respect to basic preference and technology parameters.venture capital, entrepreneurship, self-selection, moral hazard

Population ageing, public debt and sustainable fiscal policy

Due to rising life expectancy and declining fertility, the world’s population is ageing rapidly. Not only does the number of elderly relative to the number of working-age people increase, so does the proportion of the very old in the general population of the aged. In consequence, government spending on pensions, health care and other services provided for the aged is increasing and has been projected to rise on an even larger scale after the turn of the century. How can the old-age social expenditures be accommodated into a sustainable path for the general government budget?2 In most European countries, public outlays allocated to the elderly are financed on a pay-as-you-go (PAYG) basis, i.e. benefits paid to retired people are directly financed by contemporaneous taxes levied on workers. In periods with dramatic swings in the age structure, the tax rate is likely to swing as well. For example, when the population is ageing, the ratio of the number of persons of drawing age to that of those of contributing age increases, and PAYG financing implies an increase in the transfers from young to old. Does that cause generational conflicts, and will the PAYG scheme eventually be undermined?
