Environmental Policy in the European Community: Harmonization or National Standards?

This paper explores the claim that the setting of environmental standards needs to be centralized in order to avoid a competitive race to the bottom. Such a claim represents a fundamental challenge to the basic theory of fiscal federalism. But the theory of interjurisdictional competition, although diverse in approach and findings, does not provide a fully compelling basis for this proposition. Moreover, the terminology is itself misleading. The paper suggests that in the absence of environmental spillover effects across jurisdictional boundaries, there remains a strong case for decentralized environmental management.     

On Efficiency of Decentralized Environmental Regulation

Contrary to conventional wisdom about an environmental race to the bottom, the theoretical literature as exemplified by Oates and Schwab [1988, Journal of Public Economics, 35:333–354] maintains that homogeneous jurisdictions’ decentralized choices are likely to be socially optimal because each locale sets capital tax rates to zero and sets optimal environmental standards. This paper shows the well-received Oates–Schwab-style efficiency result is not likely if allowed aggregate-emissions act as a firm-augmenting public input that benefits mobile firms.Thanks to participants at the University of Alberta and the reviewers and editors for their helpful comments     

Roads out of poverty? Assessing the links between aid,public investment,growth, and poverty reduction

This paper presents a dynamic macroeconomic model that captures key linkages between foreign aid, public investment, growth, and poverty. Public capital is disaggregated into education, core infrastructure, and health. Dutch disease effects associated with aid are accounted for by endogenizing changes in the relative price of domestic goods. The impact of shocks on poverty is assessed through partial elasticities and household survey data. The model is calibrated for Ethiopia and changes in the level of nonfood aid are simulated. The amount by which (nonfood) aid should increase to reach the poverty targets of the Millennium Development Goals is also calculated, under alternative assumptions about the degree of efficiency of public investment.     

论诚信征税机制的构建——基于制度经济学的视角

税收作为社会经济活动的一项主要内容,当前面临着诚信问题,尤其是征税诚信已经成为构建税收诚信体系亟待解决的问题。因此,通过有效的制度安排,建立和完善诚信征税机制具有重要的现实意义。本文建议主要通过四个方面来实现诚信征税:一是加强税收制度建设,实施正式约束;二是优化税收征管体制,完善制度实施保障机制;三是建立税收诚信文化,实施非正式约束;四是建立激励惩罚机制,约束征税人微观行为。     

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

Corporate taxation, debt financing and foreign-plant ownership

This paper compares domestically and foreign-owned plants with respect to their debt-to-assets ratio and analyzes to which extent the difference is systematically affected by corporate taxation. To derive hypotheses about influence of corporate taxation on a firm's debt financing we adapt a standard model of taxation and financing decisions of firms for the case of international debt shifting activities of foreign-owned firms. We estimate the average difference between a foreign-owned and a domestically owned firm's debt ratio, treating the mode of ownership as endogenous. Using data from 32,067 European firms, we find that foreign-owned firms on average exhibit a significantly higher debt ratio than their domestically owned counterparts in the host country. Moreover, this gap in the debt ratio increases with the host country's statutory corporate tax rate.     

Mergers and corporate debt financing

We investigate the effect of mergers on corporate debt financing using time series analysis. We find that corporate debt use increases during periods of very high merger activity but is not significantly affected by variations within the normal range of merger activity. Traditional trade-off and pecking order variables also significantly affect corporate financing choice.     

DO SMALL DEPOSITORS EXIT FROM BAD BANKS? EVIDENCE FROM SMALL FINANCIAL INSTITUTIONS IN JAPAN*

This paper empirically investigates the issues of depositor discipline by examining deposit shifts among Japan's small banking institutions in the 1990s. We are concerned with two questions: (i) whether depositor discipline has effectively worked since the early 1990s, and (ii) whether changes in the regulatory frameworks, including the deposit insurance scheme, affect depositor discipline. Our findings support the effective role of market discipline by depositors. Riskier institutions attract smaller amounts of deposits and are required to pay higher interest rates. Depositor sensitivity to bank risks has changed over time, in compliance with the historical developments of the deposit insurance system.JEL Classification Numbers: G21, G32.     

Taxation, agency conflicts, and the choice between callable and convertible debt

We analyze debt choice in light of taxes and moral hazard. The model features an infinite sequence of nonzero-sum stochastic differential games between equity and debt. Closed-form expressions are derived for all contingent-claims. If equity can increase volatility without reducing asset drift, callable bonds with call premia are optimal. Although callable bonds induce risk shifting, call premia precommit equity to less frequent restructuring and are tax-advantaged. Convertible bonds mitigate risk shifting, but only induce hedging if assets are far from the default threshold. Convertibles are optimal only if risk shifting reduces asset drift sufficiently.     

Knowledge Capital and Venture Capital Investments: New Evidence from European Panel Data

Abstract. Countries with a high amount of knowledge capital are likely to have higher volumes of venture capital (VC) investments because more researchers come up with innovative business ideas that require venture capital finance. Using panel data techniques, the paper finds evidence that VC investments depend strongly on the countries' knowledge capital measured by the number of patents, or the number of R&D researchers, or gross domestic expenditures on R&D. In addition, the paper analyzes whether government-financed knowledge capital fulfills a special role for VC investments. It finds only weak evidence that VC investments depend, with a delay of several years, on government-financed knowledge capital.
