By using new and unusual data sets for large samples of firms in Estonia, Latvia and Lithuania we find that, since privatization, diverse patterns of enterprise ownership have emerged and ownership configurations are quite dynamic.   To test competing theories on the productivity effects of alternative ownership structures, identical cross sectional production functions specifications are estimated for each country for varying years during 1993 1996. While the effects of private ownership upon productivity are found to vary considerably over time and across countries, productivity effects are always found to be either zero or positive, thus providing partial support for the hypothesis that state ownership is less efficient than private ownership.   Findings are mixed concerning hypotheses on the effects of particular ownership structures. Often (e.g. for Lithuania) estimates indicate that all forms of private ownership have zero productivity effects. However, some estimates for Estonia provide support for the mainstream hypothesis that outside (and especially foreign) ownership is preferred to insider ownership. But in other estimates (again for Estonia) majority ownership by employees is found to deliver better business performance than majority ownership by managers (thus refuting the hypothesis that the preferred form of insider ownership is ownership by managers).  相似文献

This paper characterizes the rate of convergence of discrete‐time multinomial option prices. We show that the rate of convergence depends on the smoothness of option payoff functions, and is much lower than commonly believed because option payoff functions are often of all‐or‐nothing type and are not continuously differentiable. To improve the accuracy, we propose two simple methods, an adjustment of the discrete‐time solution prior to maturity and smoothing of the payoff function, which yield solutions that converge to their continuous‐time limit at the maximum possible rate enjoyed by smooth payoff functions. We also propose an intuitive approach that systematically derives multinomial models by matching the moments of a normal distribution. A highly accurate trinomial model also is provided for interest rate derivatives. Numerical examples are carried out to show that the proposed methods yield fast and accurate results.  相似文献

Competitive small-dimension international trade models perform well in comparing free (or restrictive) trade with autarky, especially in emphasizing that consumption patterns can differ from production patterns and that production becomes highly concentrated while consumption patterns are expanded. Variations on these small-dimensional models can usefully show how with trade production patterns may nonetheless be more diverse and a country’s labor force become more heterogeneous in its skills. The paper illustrates how the Middle Products framework can be reinterpreted to support variety in production and in labor skills.   相似文献

With implications for navigation, safety, entertainment and vehicle maintenance as well as regulation and infrastructure investment in roads, telematics has the potential to transform driving more than any other innovation for decades. In the already well-established Asian telematics industry, revenue tends to come from extra charges at the time of vehicle-sale, with most subsequent services provided free. The US model has evolved differently, with much of the cost of telematics hardware and software subsidized in the initial vehicle sale price and revenue coming from services used. The decision to invest in telematics is therefore riskier in the US. This article first briefly summarizes the potential of telematics. It then analyzes the investment risks, particularly for automakers. It concludes with recommendations on how the US auto industry can minimize risk and make the most of the opportunities.  相似文献

This paper reassesses the controversial view which has assumed that, at some point in the future, the global automobile industry, having reached maturity, would naturally migrate to the leading developing countries where the markets are growing more rapidly and wages are substantially lower. The authors argue that the threshold facing a developing country seeking to establish a domestic automobile industry has risen because of two recent developments: the rise of Japan as a major automobile producer; and a new wave of technological and organizational innovation. This involves use of state-of-the-art microelectronics and flexible manufacturing system, as well as complete restructing of component supply resulting in considerable unit cost and lead-time advantages.The authors look at what these trends mean for both the OECD and the developing countries. They outline the conventional view in more detail and then present an alternative analysis of the evolution of the industry. New policy options for the developing countries are spotlighted.  相似文献

In 1882 new statutes were prepared for the University and colleges of Oxford. This paper looks at the legislative developments leading up to these changes, and by examining the case of Magdalen College shows how these external pressures led to the replacement of charge and discharge accounting by double entry bookkeeping and the appointment of external auditors.  相似文献

In January 1999, President Carlos Menem suggested replacing the Argentine peso with the U.S. dollar. President Menem's announcement has sparked a debate throughout Latin America and Eastern Europe about what has been termed "dollarization." That debate prompted U.S. Treasury Secretary Robert Rubin to deliver a major policy speech on alternative exchange-rate regimes on April 21, 1999 and the U.S. Senate Banking Committee to hold dollarization hearings the following day featuring Fed Chairman Alan Greenspan and Deputy Secretary of the Treasury Lawrence Summers.
This article presents a case for officially dollarizing Argentina. Dollarization is not new. Unofficial dollarization is widespread in emerging market countries; in fact, as much as 70% of the stock of U.S. dollars now circulates abroad. Twenty-eight countries and dependent territories are officially dollarized. Although official dollarization would result in Argentina losing seigniorage of about 0.22 percent of GDP, the author estimates that this cost would be more than offset by a reduction in interest rates that would increase Argentina's trend rate of GDP growth by about two percent.
After debunking the most common criticisms of dollarization, the article closes by offering recommendations about the specific form of dollarization and presenting a detailed dollarization statute for Argentina. The author proposes a competitive currency regime for Argentina, one in which all foreign money would be legal tender.  相似文献

Most innovation studies focus on the activities or characteristics of individuals (agency) or on organizational attributes such as size and formalization (structure). In attempting to reconcile this agency-structure dichotomy we draw on structuration theory to examine the innovation process in detail. Structural properties (signification, domination and legitimation) are constantly reproduced from social interaction (communication, power and sanctions) by means of the modalities (interpretative schemes, facilities and norms) drawn on by knowledgeable, reflexive actors. This framework is utilized to examine the case of a mature manufacturing company in which managers and engineers were attempting to access new technologies. The data were acquired by means of a 6-year, on-going study which began in 1992 and which we suggest is essential for a thorough understanding of the innovation process.  相似文献
