Lopez-de-Silanes, Florencio, Rafael LaPorta, Andrei Shleifer, and Simon Johnson. 2000. Tunnelling.Abstract
Tunnelling is defined as the transfer of assets and profits out of firms for the benefit of their controlling shareholders. We describe the various forms that tunnelling can take, and examine under what circumstances it is legal. We discuss two important legal principles — the duty of care and the duty of loyalty — which courts use to analyze cases involving tunnelling. Several important legal cases from France, Belgium, and Italy illustrate how and why the law accommodates tunnelling in civil law countries, and why certain kinds of tunnelling are less likely to pass legal scrutiny in common law countries.
Marin, Guillermo. 2000. La Tercera Revolucion de la Diplomacia.Abstract
La primera revolución de la diplomacia fue la de su nacimiento como institución. En realidad, el arte u oficio de las relaciones internacionales existe desde que se produjeron los primeros contactos entre pueblos diferentes, durante la más remota Antigüedad. Se sabe que, ya en el siglo XIV a.C., había algún tipo de relación formal entre egipcios y habitantes de la Mesopotamia. Pero fue el contacto estrecho entre las ciudades–estado de la Grecia clásica lo que dio origen a la diplomacia institucionalizada. Heraldos y un cierto código de conducta le otorgaron carta de naturaleza. Las relaciones diplomáticas de esta primera época tenían carácter puntual. A partir de entonces, paulatinamente, el poder político se fue centralizando y la comunicación entre las distintas entidades que lo albergaban se fue intensificando.
Kremer, Michael. 2000. Retrospective vs. Prospective Analyses of School Inputs:The Case of Flip Charts in Kenya.Abstract
This paper compares retrospective and prospective analyses of the effect of flip charts on test scores in rural Kenyan schools. Retrospective estimates that focus on subjects for which flip charts are used suggest that flip charts raise test scores by up to 20 percent of a standard deviation. Controlling for other educational inputs does not reduce this estimate. In contrast, prospective estimators based on a study of 178 schools, half of which were randomly selected to receive charts, provide no evidence that flip charts increase test scores. One interpretation is that the retrospective results were subject to omitted variable bias despite the inclusion of control variables. If the direction of omitted variable bias were similar in other retrospective analyses of educational inputs in developing countries, the effects of inputs may be even more modest than retrospective studies suggest. Bias appears to be reduced by a differences–in–differences estimator that examines the impact of flip charts on the relative performance of students in flip chart and other subjects across schools with and without flip charts, but it is not clear that this approach is applicable more generally.

LaPorta, Rafael, Florencio Lopez-de-Silanes, Andrei Shleifer, and Robert W Vishny. 2000. Government Ownership of Banks.Abstract
In this paper, we investigate a neglected aspect of financial systems of many countries around the world: government ownership of banks. We assemble data which establish four findings. First, government ownership of banks is large and pervasive around the world. Second, such ownership is greater in countries with low levels of per capita income, backward financial systems, interventionist and inefficient governments, and poor protection of property rights. Third, higher government ownership of banks in 1970 is associated with slower subsequent financial development. Finally, higher government ownership of banks in 1970 is associated with lower subsequent growth of per capita income, and in particular with lower growth of productivity rather than slower factor accumulation. This evidence is inconsistent with the optimistic "development" theories of government ownership of banks common in the 1960s, but supports the more recent "political" theories of the effects of government ownership of firms.
LaPorta, Rafael, Florencio Lopez-de-Silanes, Andrei Shleifer, and Robert W Vishny. 2000. Agency Problems and Dividend Policies Around the World.Abstract
This paper outlines and tests two agency models of dividends. According to the "outcome" model, dividends are the result of effective pressure by minority shareholders to force corporate insiders to disgorge cash. According to the "substitute" model, insiders interested in issuing equity in the future choose to pay dividends to establish a reputation for decent treatment of minority shareholders. The first model predicts that stronger minority shareholder rights should be associated with higher dividend payouts; the second model predicts the opposite. Tests on a cross–section of 4,000 companies from 33 countries with different levels of minority shareholder rights support the outcome agency model of dividends.
Kremer, Michael. 2000. Outside Funding of Community Organizations: Benefiting or Displacing the Poor?.Abstract
In response to the widespread consensus on the importance of social capital, and to concerns about the scarcity of institutions giving voice to disadvantaged groups, some donors have begun programs designed to strengthen indigenous community organizations. We use a prospective, randomized evaluation to examine a development program explicitly targeted at building social capital among rural women's groups in western Kenya. The program increased turnover among group members. It increased entry into group membership and leadership by younger, more educated women, by women employed in the formal sector, and by men. The analysis suggests that providing development assistance to indigenous community organizations of the disadvantaged may change the very characteristics of these organizations that made them attractive to outside funders.
Kremer, Michael. 2000. A World Bank Vaccine Commitment.Abstract
For a general program to combat communicable diseases of the poor to stimulate research, it must include an explicit commitment to help finance the purchase of new vaccines if and when they are developed. Without an explicit commitment along the lines proposed by Wolfensohn, it is unlikely that the large scale investments needed to develop vaccines will be undertaken.

Kremer, Michael. 2000. Globalization and International Public Finance.Abstract
This paper examines the effect of reduced transaction costs in the international trading of assets on the ability of governments to issue debt. We examine a model in which governments care about the welfare of their citizens, and thus are more inclined to default if a large proportion of their debt is held by foreigners. Reductions in transaction costs make it easier for domestic citizens to share risk by selling debt to foreigners. This may increase tendencies for governments to default, and thus raise their cost of credit and reduce welfare. We find that even in the absence of transaction costs, home bias in placement of government debt may persist, because in the presence of default risk the return on government debt is correlated with the tax burden required to pay the debt. Asset inequality may reduce this home bias, and by increasing foreign ownership, increase incentives for default. Finally, if foreign creditors are less risk averse than domestic creditors, there may be one equilibrium in which domestic creditors hold the asset and default risk is low, and another in which foreign creditors hold the asset and default risk is high.
Kremer, Michael. 2000. Income-distribution Dynamics with Endogenous Fertility.Abstract
Developing countries with highly unequal income distributions, such as Brazil or South Africa, face an uphill battle in reducing inequality. Educated workers in these countries have a much lower birthrate than uneducated workers. Assuming children of educated workers are more likely to become educated, this tends to increase the proportion of unskilled workers, reducing their wages, and thus their opportunity cost of having children, creating a vicious cycle. A model incorporating this effect generates multiple steady–state levels of inequality, suggesting that in some circumstances, temporarily increasing access to educational opportunities could permanently reduce inequality. Empirical evidence suggests that the fertility differential between the educated and uneducated is greater in less equal countries, consistent with the model.
Kremer, Michael. 2000. A Better Way to Spur Medical Research and Development.Abstract
Today, the United States government spurs research mainly through direct funding and the granting of patents. Both methods are vitally important, but each causes serious problems–and each has proved inadequate in spurring the research needed to develop effective vaccines against HIV, tuberculosis and malaria.
Kornai, Janos. 2000. Ten Years After 'The Road to a Free Economy', The Author's Self Evaluation.Abstract
Ten years have passed since the publication of my book The Road to a Free Economy: Shifting from a Socialist System–the Example of Hungary. It was the first book in the international literature to put forward comprehensive proposals for the post–socialist transition. This paper sets out to assess the book as the author sees it ten years later.
Kremer, Michael. 2000. Creating Markets for New Vaccines: Part 1: Rationale (in Innovation Policy and the Economy).Abstract
Malaria, tuberculosis, and the strains of HIV common in Africa kill approximately 5 million people each year. Yet research on vaccines for these diseases remains minimal—largely because potential vaccine developers fear that they would not be able to sell enough vaccine at a sufficient price to recoup their research expenditures. Enhancing markets for new vaccines could create incentives for vaccine research and increase accessibility of any vaccines developed. For example, the World Bank has proposed establishing a fund to help developing countries finance purchases of specified vaccines if they are invented. The U.S. administration’s budget proposal includes a tax credit for new vaccines that would match each dollar of vaccine sales with a dollar of tax credits. This paper examines the rationale for such proposals. Private firms currently conduct little research on vaccines against malaria, tuberculosis, and the strains of HIV common in Africa. This is not only because these diseases primarily affect poor countries, but also because vaccines are subject to severe market failures. Once vaccine developers have invested in developing vaccines, government are tempted to use their powers as regulators, major purchasers, and arbiters of intellectual property rights to force prices to levels that do not cover research costs. Research on vaccines is an international public good, and none of the many small countries that would benefit from a malaria, tuberculosis, or HIV vaccine has an incentive to encourage research by unilaterally offering to pay higher prices. In fact, most vaccines sold in developing countries are priced at pennies per dose, a tiny fraction of their social value. More expensive, on–patent vaccines are typically not purchased by the poorest countries. Hence, private developers lack incentives to pursue socially valuable research opportunities. Large public purchases could potentially enlarge the market for vaccines, benefiting both vaccine producers and the public at large.
Kremer, Michael. 2000. Creating Markets for New Vaccines: Part 2: Design Issues (in Innovation Policy and the Economy).Abstract
Several programs have been proposed to improve incentives for research on vaccines for malaria, tuberculosis, and HIV, and to help increase accessibility of vaccines once they are developed. The U.S. administration's budget proposes a tax credit that would match each dollar of vaccine sales with a dollar of tax credit. The World Bank has proposed a $1 billion fund to provide concessional loans to countries to purchase vaccines if and when they are developed. European political leaders have spoken favorably about the concept of a vaccine purchase fund. This paper explores the design of such programs, focusing on commitments to purchase new vaccines. For vaccine purchase commitments to spur research, potential vaccine developers must believe that the sponsor will not renege on the commitment once vaccines have been developed and research costs sunk. Courts have ruled that similar commitments are legally binding contracts. Given appropriate legal language, the key determinant of credibility will therefore be eligibility and pricing rules, rather than whether funds are physically set aside in separate accounts. The credibility of purchase commitments can be enhanced by specifying rules governing eligibility and pricing of vaccines in advance and insulating those interpreting these rules from political pressure through long terms. Requiring candidate vaccines to meet basic technical requirements, normally including approval by some regulatory agency, such as the U.S. FDA, would help ensure that funds were spent only on effective vaccines. Requiring developing to contribute co–payments would help ensure that they felt that the vaccines were useful given the conditions in their countries. The U.S. Orphan Drug Act's success in stimulating research and development is widely attributed to a provision awarding market exclusivity to the developer of the first drug for a condition unless subsequent drugs are clinically superior. Purchases under a vaccine purchase program could be governed by a similar market exclusivity provision. A purchase commitment program could start by offering a fairly modest price. If this proved inadequate to spur sufficient research, the promised price could be increased. This procedure mimics auctions, which are often efficient procurement methods when costs are unknown. As long as prices do not rise at a rate substantially greater than the interest rate, vaccine developers would not have incentives to withhold vaccines from the market. The World Bank has termed health interventions costing less than $100 per year of life saved as highly cost effective for poor countries. If donors pledge approximately $250 million per year for each vaccine for ten years, vaccine purchases would cost approximately $10 per year of life saved. It is unlikely that vaccines for all three diseases would be developed simultaneously, but if donors wanted to limit their exposure, they could cap their total promised vaccine spending under the program, for example at $520 million annually. No funds would be spent or pledges called unless a vaccine were developed.
Kremer, Michael. 2000. Stimulating R&D on Vaccines for AIDS, Tuberculosis, and Malaria: The Role of Tax Credits for Sales of Vaccines to Non-Profit Org.Abstract
The Vaccines for the New Millennium Act (HR 3812; SR 2132) includes both enhanced R&D tax credits and a tax credit for sales of vaccines to non–profits and international organizations. The combination is likely to be effective. The enhanced R & D tax credit will provide an immediate benefit for firms doing research in the area. The tax credits for sales will provide incentives for firms to follow through by designing appropriate vaccines for the regions where the diseases are most deadly and will help increase accessability of any vaccines developed. There are several reasons why tax credits for sales of vaccines are an essential element of any package to promote vaccine R&D.

Kim, Wi Saeng. 2000. Does FDI Increase Firm Value in Emerging Markets?.Abstract
The study finds that positive and statistically significant abnormal returns occur around the announcement date of foreign direct investments. The finding suggests that security prices in the Korean stock market do reflect firm-specific information, and that FDI by Korean MNCs are, on average, value increasing investment decisions. The finding is consistent with the studies of Doukas and Travlos (1988) and Fatemi (1984) which found similar results for U.S. MNCs. Interestingly, however, the speed of price adjustment is not instantaneous as has been observed in event studies of the U.S. market. The price adjustment to firm–specific information is slower, and the magnitude of abnormal returns is greater, for the firms that are subject to investor herding behavior.

Kapur, Devesh. 2000. Processes of Change in International Organizations.Abstract
Although international institutions are a ubiquitous feature of international life, little is know about their trajectories of change. This paper attempts to address this lacuna by examining processes of change in international institutions, in particular the subset of international institutions known as inter–governmental organizations. The purpose of this paper is not to develop a general theory of change in international institutions but rather to develop limited generalizations about causal mechanisms and their consequences. It first examines the rationale and purposes of international organizations – before we can ask how and why particular types of organizations change, we need to understand why they exist in the first place. It then examines the trajectories of change in international organizations by posing three, interrelated, questions. One, what factors drive (or hinder) change in international institutions and organizations and what are the principal instruments and mechanisms that leverage change? Two, what factors explain variations in the pace and direction of change? And three, what are the consequences of change both for the institutions themselves and for their members? Finally the paper outlines a research agenda to develop a broad theoretical framework for understanding causal mechanisms of change in international organizations.
