In an attempt to better understand the impact of the World Bank on human development in poor countries, we use cross-country data on African countries for the 1990–2002 period to examine this relationship. The coefficient estimates of our parsimonious fixed-effects models indicate that while loans and grants of the Bank have had a positive impact on some relatively short-term indicators of health and education in an average African country, there is little evidence to suggest that such loans and grants have helped these countries to consolidate on the short-term gains.  相似文献

The paper formulates and estimates for India for the period 1950–1980 an aggregate production function wherein the supply of real money balances in the economy appears as a limitational factor of production. The rationale for the formulation is argued from the importance of working capital funds in organising production, and how the supply of money, or the lack thereof, may constrain its availability in a financially underdeveloped economy characterized by imperfect capital markets.Comments and suggestions by annonymous referees for the journal as well as by the participants in the seminar at the Institute of Economic Growth, Delhi, India and the session on money and production at the Windsor meetings of the Canadian Economic Association are gratefully acknowledged. Thanks are also due Mr. Salah Foda for programming assistance.  相似文献

This paper explores the critical factors which affect the innovation proccess. Some ways in which some of these factors can be influenced by appropriate policy measures are discussed. In particular, the role of the federal government in promoting innovation is discussed.The role of the government in stimulating and nurturing the innovation process is a controversial one. Proponents of the free enterprise system, many of whom are spokespersons for various industries, have persistently pointed out the deleterious effects of regulation and control on the innovation process. By contrast, advocates of an activist government role are often able to cite the protection of the common welfare as a primary need for government intervention. In truth, the “government” is a patchwork of many governments, operating through many agencies and affecting firms and individuals at several levels and leverage points. The same regulation that has deleterious effects on Industry A may be a stimulus for innovation in Industry B. Even in Industry A, the regulation may act as a force in directing efforts toward certain types of R&D programs that would not otherwise be undertaken.In this paper we examine the specific instances where innovation projects, both product or process types, were affected by government regulation. We also briefly review the critical factors which affect the innovation process and how various governments in industrialized countries have taken actions to influence these factors. Finally, we examine some general guidelines for policymaking purposes.  相似文献

ABSTRACT

This study examines the four commonly tested hypotheses in hydroelectricity consumption – economic growth literature for 12 Asian countries. Our results from a recently developed hidden cointegration technique uncover rich and significant relationships between negative and positive components of the variables under consideration. In particular, we find evidence to support the neutrality hypothesis in five countries (Bangladesh, Indonesia, Pakistan, Philippines, and Thailand), the growth hypothesis in four countries (India, Japan, South Korea and Taiwan), and both growth and conservation hypotheses in three countries (China, Malaysia, and New Zealand). These findings suggest that appropriate economic policies should be elaborated on the basis of the country’s specific hydroelectricity consumption–growth nexus. Finally, our new evidence suggests that the lack of stable relationship between hydroelectricity consumption and economic growth documented in previous studies for some of these countries could be due to the failure to properly account for the nonlinearity property in the data.  相似文献

We examine and compare a large number of generalized autoregressive conditional heteroskedastic (GARCH) and stochastic volatility (SV) models using series of Bitcoin and Litecoin price returns to assess the model fit for dynamics of these cryptocurrency price returns series. The various models examined include the standard GARCH(1,1) and SV with an AR(1) log-volatility process, as well as more flexible models with jumps, volatility in mean, leverage effects, t-distributed and moving average innovations. We report that the best model for Bitcoin is SV-t while it is GARCH-t for Litecoin. Overall, the t-class of models performs better than other classes for both cryptocurrencies. For Bitcoin, the SV models consistently outperform the GARCH models and the same holds true for Litecoin in most cases. Finally, the comparison of GARCH models with GARCH-GJR models reveals that the leverage effect is not significant for cryptocurrencies, suggesting that these do not behave like stock prices.  相似文献

The transition to the circular economy (CE) creates value through the closed-loop systems, reverse logistics, product life cycle management, and clean production in terms of corporate environmental management. During this transition process, the organization faces many barriers such as financial, organizational, technology-based, social, policy-related, market-based, and logistics-based barriers. The objectives of this study are to propose a framework highlighting policy-related barriers for a supply chain in the transition to CE and finally discuss potential implications on enhancing corporate environmental performance of a business. Further, this study evaluates the causal relationships between the policy-related barriers using fuzzy Decision-Making Trial and Evaluation Laboratory (DEMATEL) method. The application was conducted in an apparel firm in Turkey. From findings, lack of legislation for efficient CE (C4), lack of mandatory requirements and responsibilities for manufacturers/suppliers for the CE (C17), and lack of government support for environmentally friendly policies (C2) are revealed as the most important barriers, respectively. It is found that lack of attitude and awareness about CE in government institutions (C19) is the most influencing factor, whereas lack of effective recycling policies to achieve quality in waste management (C8) is the most influenced factor. The recommendations were developed for enhancing the corporate environmental performance of businesses through incentives and unique rewards, improving communication among stakeholders, the government's perception of CE and current linear economy, cooperation with nongovernmental organization (NGOs) and civil actions, the vision of government towards circular principles, the circular public procurement, the local governments in circular policymaking, and awareness of bureaucracy and government officials.  相似文献
