Reforming tax systems - the World Bank record in the 1990s

The main constraint on world Bank operations in tax and customs administration is the Banks inadequate institutional framework for accumulating knowledge from loan operations, concludes this review of the Banks record on reform of tax systems in the 1990s. The Banks theoretical basis for reforming tax and customs administration is still rudimentary. Recent theories stress the importance of institutions that harness voice and improve transparency and contestability, but there is little evidence that reform of these factors alone makes tax administration more effective. Improvements are needed in pre-project diagnosis and project design, especially for examining accountability, administration costs, managerial autonomy, performance incentives for staff, taxpayer equity and services, and environmental factors. Pre-project work could draw more systematically on lessons from previous experience. Institutional components of project design have been biased toward organization, manpower upgrading, and procedures related to information technology. Too little attention has been paid to improving accountability, administrative cost-effectiveness, and anticorruption institution-building. Projects have made inadequate use of different kinds of performance indicators, with little uniformity in those applied. Methods used to evaluate project outcomes could be better and more uniform. Suggestions for future Bank operations: 1) doing better background work and articulating a strategy and comprehensive framework for Bank involvement in reform of tax administration. 2) Possibly supporting and strengthening regional tax administration associations, which could serve as catalysts for change. 3) Strengthening partnering and supporting private sector consultant organizations, so they can manage major components of administrative reform. 4) Institutionalizing the accumulation of knowledge about tax administration (which might require changing staff recruitment, the mix of staff skills, and training plans). The authors provide recommendations for improving project diagnosis, design, performance indicators, and appraisal, as well as a short list of projects that serve as guides to good practice.

EU Accession of Central and Eastern Europe: Bridging the Income Gap

The countries of Central and Eastern Europe (CEE) have much to gain from implementing policies that increase investment, support the development of human capital, and promote the legal, regulatory, and policy framework needed for market mechanisms to function. The faster they implement such changes, the faster they will bridge the income gap between them and the countries of the European Union - and the more likely their chances of successful integration. Joining the European Union (EU) is perhaps the key political and economic objective of Central and Eastern European (CEE) countries as they approach the 21st century. But how successful the CEE countries are in achieving this goal depends not only on how well and quickly they adapt their legal and regulatory systems to EU requirements but on how well and quickly they bridge the wide income gaps between CEE and EU countries. Using a model and cross-section data to develop estimates, Barbone and Zalduendo investigate how appropriate structural policies adopted before and after accession to the EU can help CEE countries bridge this income gap. They have much to gain from implementing policies that increase investment, support the development of human capital, and promote the legal, regulatory, and policy framework needed for market mechanisms to function. The faster they implement such changes, the faster they will bridge the income gap between them and the EU countries - and the more likely their accession to the EU will be successful. This paper - a product of Country Department II, Europe and Central Asia - is part of a larger effort in the department to examine issues related to accession to EU by Central and Eastern European countries.

The Costs of VAT: A Review of the Literature

This paper reviews the published literature on the definition and measurement of the administrative and compliance costs of taxation, with special reference to VAT (including evasion and fraud) in the European Union.

Structural Adjustment, Ownership Transformation, and Size in Polish Industry

The authors argue that significant adjustment took place in Polish industry after Polands 1990 reforms. They analyze data on two- and three-digit manufacturing industries, disaggregated by firm ownership and size. By applying a statistical model to labor productivity growth, they try to disentangle structural determinants of the recovery from cyclical determinants. They contend that structural determinants outweigh cyclical ones. They find that the productive response of state enterprises was markedly different from that of private firms--private firms outperformed state enterprises (just as anecdotal evidence suggested). Size also matters, at least among private firms. Generally, there seem to be increasing returns to scale for private firms, except for very large enterprises (many of which were previously state-owned and may need further restructuring). The fact that size does not appear to matter among public enterprises suggests that several of them have not yet adopted optimal technologies and production processes.

Tajikistan: Key Priorities for Climate Change Adaptation

How should Tajikistan adapt to ongoing and future climate change, in particular given the many pressing development challenges it currently faces? The paper argues that for developing countries like Tajikistan, faster economic and social development is the best possible defense against climate change. It presents some key findings from a recent nationally representative household survey to illustrate the strong public support for more climate change related spending on better management of water resources, disaster management, agriculture, and public health--four key sectors that the governments latest poverty reduction strategy identifies as being especially important from a climate change perspective. Finally, the paper argues that, as important as project-based adaptation measures may be, it is imperative that they be supported by an overall policy framework that provides a truly enabling environment to facilitate faster climate change adaptation.

Post-Crisis Lesson for EMU Governance from the Principal-Agent Approach

This paper contributes to the ongoing debate on fiscal consolidation and the questionable effectiveness of the Stability and Growth Pact by addressing the problem of economic governance in the EMU with a game-theoretic principal-agent approach. Following the theory of delegation, we develop a principal-multi agent model where the EMU authorities act as a collective principal that designs contracts for each of two agents that reflect Europe’s ”South” and ”North”. We investigate what happens when agents face hidden-information moral hazard problem and when they are able to coordinate their actions. Bearing in mind the applicability of incentive mechanisms, we discuss the optimal contracts for the principal and each of the agents. We prove that the most efficient solution consists of tailor-made contracts, according to which highly indebted countries must be offered strong incentive mechanisms in the form of substantial penalties but also rewards (e.g., preferential loans). We also stress the importance of taking into account positive spillover effects, which could be facilitated by economic integration and fiscal policy coordination between the EMU Members.

Structural Adjustment, Ownership and Size in Polish Manufacturing

This paper argues that a significant adjustment process has taken place in Polish industry after the 1990 market oriented reforms. We analyze comprehensive data on two-digit and three-digit manufacturing industries, disaggregated by firm ownership and size. By focusing on a decomposition of labor productivity growth, we obtain results which suggest that structural determinants of the recovery have outweighed cyclical ones. With regard to firm ownership and economic performance, we find that the productive response of state enterprises has been markedly different from that of private firms, with the latter outperforming the former. Finally, our results indicate that size matters, at least among private firms, and provide mild evidence of increasing returns.
