    Abstract: This paper discusses decentralization (administrative, fiscal and political) of government in public service provision. It aims to facilitate understanding among practitioners, policy makers, and scholars about what decentralization entails in practice compared to theory. A review of the empirical literature and experience of decentralization is presented. The paper highlights issues that policy makers in developing and transitional countries should be aware of when reforming government, considering t heir unique political and economic environment. The author argues that decentralization produces efficiency gains stemming from inter-jurisdictional competition, enhanced checks and balances over the government through voting at the subnational level, and informational advantages due to proximity to citizens. By contrast, arguments against decentralization include the risk of an increased level of corruption, coordination problems stemming from multiple layers of government, low capacity of subnational government, and unproductive inter-jurisdictional competition. Decentralization itself does not render increased government effectiveness in public service provision. Instead, the effectiveness of government largely depends on the quality of human capital and institutions.

    Abstract: This paper provides a first approach to the analysis of the determinants of public balances of regional (Autonomous) governments. These determinants have been divided into economic, political and institutional factors and into those factors specific to lower levels of government (fiscal federalism). With data referring to the years 1984-2004, the approach followed helps us to conclude that the debt and deficit ceilings established in the so-called Fiscal Consolidation Scenarios (Escenarios de Consolidación Presupuestaria), in force during the 1990s, do not seem to have had a significant effect on the regional governments balances, while a higher degree of fiscal co-responsibility seems to be associated with a more disciplined behaviour of sub-central governments. Likewise, the analysis shows that a higher degree of fiscal decentralization is accompanied by a higher dependence of the evolution of regional governments’ public budgets on the economic cycle. The implementation of fiscal policy in the regional governments seems, finally, to incorporate a strong inertial component. In any case, the small number of observations of the series used, the existence of important institutional changes during the period of analysis and the high number of explanatory variables, that is, the large number of potential determinants of public balances, oblige us to treat our results with the greatest care.

    Abstract: This paper studies optimal direct and indirect taxation rules in an endogenous growth framework where public goods, in the form of infrastructure and health services, affect both production and household utility. Growth- and welfare-maximizing rules are first derived in a setting where collection costs are absent. The analysis is then extended to consider the case where tax collection is costly. Optimal tax rules are derived under alternative assumptions about the nature of these costs. The possibility of multiple equilibria is examined, together with the joint determination of the tax structure and the share of public spending on tax enforcement.

    Abstract: For many kinds of capital, depreciation rates change systematically with the age of the capital. Consider an example that captures essential aspects of human capital, both regarding its accumulation and its depreciation: a worker obtains knowledge in period 0, then uses this knowledge in production in periods 1 and 2, and thereafter retires. Here, depreciation accelerates: it occurs at a 100% rate after period 2, and at a lower (perhaps zero) rate before that. The present paper analyzes the implications of non-constant depreciation rates for the optimal timing of taxes on capital income. The main finding is that under natural assumptions, the path of tax rates over time must be oscillatory. Oscillatory tax rates are optimal when depreciation rates accelerate with the age of the capital (as in the above example), and provided that the government can commit to the path of future tax rates but cannot apply different tax rates in a given year to different vintages of capital.

  5. By: John F. Cogan; R. Glenn Hubbard; Daniel P. Kessler
    Abstract: In this paper, we estimate the effect of the tax preference for insurance on health spending based on the Medical Expenditure Panel Surveys from 1996-2005. We use the fact that Social Security taxes are only levied on earnings below a statutory threshold to identify the tax preference's impact. Because employer-sponsored health insurance premiums are excluded from Social Security payroll taxes, workers who earn just below the Social Security tax threshold receive a larger tax preference for health insurance than workers who earn just above it. We find a significant effect of the tax preference, consistent with previous research.

    Abstract: This paper studies the mechanisms behind the informal economy in high-income countries. About 16.3% of output in high-income OECD countries was produced informally in 2001-02. In a recent paper Davis and Henrekson [2004] show that there exists a positive relationship between tax rates and the informal economy for high-income OECD countries. Existing models of the informal economy mostly focus on developing countries. To account for the informal economy in high-income countries, build a model economy, following Lucas [1978], in which agents of different managerial abilities decide to become workers, managers of informal firms, or managers of formal firms. In contrast to formal managers, managers of informal firms do not pay taxes but run the risk of getting caught, taxed, and fined. A calibrated version of the model economy is able to generate the observed differences in informal economy of 21 high-income countries. Although tax rates are crucial for explaining the observed differences in informal economy, the quality of governance, the extent to which these tax rates are enforced, also plays an important role. Policy experiments show that by improving the enforcement of their tax policies countries can reduce informality. A smaller informal economy is accompanied by larger firms and higher productivity.

    Abstract: Taxation theory rarely takes entrepreneurship into consideration. We discuss how this omission affects conclusions derived from standard models of capital taxation when applied to entrepreneurial income. Some of the defining features of entrepreneurship often omitted by standard capital taxation theory are incorporated into the analysis. This includes the lack of a well-functioning external market for entrepreneurial effort, limited access to external capital and the complementarities between entrepreneurial effort, entrepre-neurial innovation and capital investment. Because of these constraints, the entrepreneurial project is tied to the individual owner-manager. Unlike the typical passive portfolio investor assumed in cost of capital models the entrepreneur is unable to decouple savings decisions from investment decisions, and due to the comple-mentarities in production makes a joint decision on the supply of effort and capital. The returns from success-ful entrepreneurial ventures thus cannot be readily divided into labor and capital income, in stark contrast to what is assumed in standard taxation theory. When unique attributes of entrepreneurship are taken into account, some major conclusions of capital taxation models no longer hold, including the neutrality of capital taxation in owner-managed firms. These results are particularly important for the Nordic system of dual taxation, the theoretical foundation of which relies on the ability to neatly separate capital income from the labor income of the self-employed.

    Abstract: A model in which a high-productivity region and a low-productivity region bargain with each firm in a group of mobile firms is constructed. It differs from the Han and Leach [7] model in that the firms are identical, so that its comparative statics are more tractable. The model is used to examine the allocative effects of equalization payments (both non-contingent payments and "corrective subsidies"). The equilibrium is characterized by misallocation of capital and underprovision of public goods. Underprovision is more severe in the low-productivity region than the high-productivity region. A transfer of revenue from the high-productivity region to the low-productivity region augments public goods provision in the low-productivity region, allowing that region to make more generous offers to the firms. Likewise, underprovsion becomes more severe in the high-productivity region, so that its offers become less generous. Equilibrium is attained by a movement of firms from the high-productivity region to the low-productivity region, reducing the misallocation of capital.

    Abstract: In Europe, declining corporate tax rates have come along with rising tax-to-GDP ratios. This paper explores to what extent income shifting from the personal to the corporate tax base can explain these diverging developments. We exploit a panel of European data on legal form of business to analyze income shifting via incorporation. The results suggest that the effect is significant and large. It implies that the revenue effects of lower corporate tax rates ¯ possibly induced by tax competition ¯ will partly show up in lower personal tax revenues rather than lower corporate tax revenues. Simulations suggest that between 12% and 21% of corporate tax revenue can be attributed to income shifting. Income shifting is found to have raised the corporate tax-to-GDP ratio by some 0.25%-points since the early 1990s.
