South Korea began its measurement of Gross National Product during the turbulent 1950's, a period of postwar rebuilding and of political and social changes. With only a small and largely inexperienced staff, and with little support from other statistical agencies whose data were essential to adequate GNP measurement, the Bank of Korea began this task in the early 1950's. Early estimates were extremely rough; over the years, the statistical staff was trained and other statistical agencies were upgraded. Measurements of output in the large agricultural sector and in manufacturing have gradually but consistently been strengthened as recent input-output data has been developed. Gaps still persist, particularly in the wholesale and retail sectors, but certain strengths are present: an outstanding job has been done in product pricing. The author describes the evolution of Korea's improving GNP program, presents its sources of data and its methodologies, and gives an assessment of problems of the past and prospects for the future. 相似文献

Using the EU‐SILC database, we estimate and compare the Inequality of Opportunity (IO) of 23 European countries in 2005. IO is estimated as the between‐type (ex‐ante) inequality component following the parametric procedure of Ferreira and Gignoux (2011 ), which allows for the inclusion of the large set of circumstances in the database. We also measure the degree of correlation between IO estimates and a set of past and contemporaneous economic factors related to the degree of development, labor market performance, investment in human capital, and social protection spending. 相似文献

Microenterprise Dynamics in Developing Countries: How Similar are They to Those in the Industrialized World? Evidence from Mexico 总被引:2,自引:0,他引:2
Fajnzylber Pablo; Maloney William; Rojas Gabriel Montes 《World Bank Economic Review》2006,20(3):389-419
A rich panel data set from Mexico is used to study the patternsof entry, exit, and growth of microenterprises and to comparethese with the findings of the mainstream theoretical and empiricalwork on firm dynamics. The Mexican self-employment sector ismuch larger than its counterpart in the United States, whichis reflected in higher unconditional rates of entry into thesector. The evidence for Mexico points to the significant presenceof well-performing salaried workers among the likely entrantsinto self-employment, as opposed to the higher incidence ofpoorer wageworkers among the entrants into the U.S. self-employmentsector. Despite these differences, however, the patterns ofentry, survival, and growth with respect to age, education,and many other covariates are very similar in Mexico and theUnited States. These strong similarities suggest that mainstreammodels of worker decisions and firm behavior are useful guidesfor policymaking for the developing-country microenterprisesector. Furthermore, they suggest that, as a first approximation,the developing-country microenterprise should probably be viewedas they are in the advanced countries as offering potentiallydesirable job opportunities to low-productivity workers. 相似文献

This theme continues and completes another interdisciplinary project launched one year ago, and its aim is to realize one or several models about e-business in Romania. As a consequence, we can speak now about an extended project. The elaborated material will be useful for a large number of companies doing business in Romanian online environment. The team wants to elaborate solutions for e-businesses, as well as to create a complex and utile work, a starting point for companies wishing to exist in web lifestyle within a global economy. It will be elaborated a manual of blog and electronic commerce, both with theoretical and applicative aspects. This project will consolidate a research nucleus in blogs, collaboration and electronic businesses at the Business Administration Department, Babes-Bolyai University. The results of this extended project will have impact on several plans on the scientific community. 相似文献

ABSTRACT Heterogeneity among trade agreements across Latin American countries is important for comparing different experiences and for evaluating the success of existing trade agreements. This note evaluates the Mercosur agreement in a counterfactual framework. Member countries’ experiences are compared to the Mexican experience in several dimensions other than trade. In particular, the effect of trade agreements is evaluated in terms of its effect on the labor market (inequality and informality) and on other measures of integration. This new analysis puts Mercosur in a more positive balance with respect to the pure trade theory analysis. 相似文献

In this paper we define manipulation with restricted beliefs as the possibility for some voter to have an insincere preference ordering that dominates the sincere one within the given individual beliefs over other agents’ preferences. We then show that all non-dictatorial voting schemes are manipulable in this sense, up to a given threshold. 相似文献

The present day city mirrors the internal conflict of modern man. He wants to live in towns and preferably in towns which are pleasant to live in. But, at the same time, he does not wish to be deprived of his car and indeed cannot do without it. Yet the present day automobile has shown itself to be incompatible with the city, or at least with a city that is good to live in. Is there any hope of resolving this dilemma in the next generation, the 26 years which will take us to the year 2000, without endangering a powerful automobile industry, probably vital to the survival of our industrial society, and without destroying our civilisation which is essentially a civilisation of town dwellers ? 相似文献

The financial theory (Modigliani & Miller, 1958) rises that risk management was not an issue for companies because shareholders could make their own hedging management through portfolio diversification; however, further studies conflict with that statement and show that corporate financial hedging improves performance and increases the value thereof (Ahmed, Azevedo, & Guney, 2014; Allayannis & Weston, 2001; Allayannis & Ofek, 1998). Efficient management of market risks, which is based on the use of financial derivatives, demands strategic and efficient managers in hedging that adds value to the firm, especially in against shocks and imbalances from a macroeconomic and financial nature. Empirical evidence analyzes the performance of the Q-Tobin as an indicator of the effect of hedging strategies of exchange rate associated to the market value. This paper aims to find evidence in Colombia on the effect of using derivatives in the market value of the firm. Its added value lies in the analysis made by economic sectors, identified by CIIU codes and grouped into 5 sectors (Agricultural, Commercial, Industrial or Manufacturing, Services and Construction). The methodology includes several models estimating regression panel data, using a Pooled regression with estimators of fixed and random effects by maximum likelihood estimator. In general, it was found a premium due to hedging, statistically and financially significant, for companies exposed to exchange rate risks that use derivatives by an average of 6.3% on the market value. Moreover, mixed results were found regarding the analyzed variables in the model. 相似文献

The stock market has been transformed during the last 25 years. Human suppliers of liquidity like the NASDAQ dealers and NYSE specialists have been replaced by algorithmic market making; stocks that once traded on a single venue now trade across twelve exchanges and a multitude of alternative trading systems. New venues like dark pools, and new participants like high‐frequency traders, have emerged to take on prominent roles. This new market has had more than its share of controversy and regulatory scrutiny, particularly in the wake of Michael Lewis’s bestseller Flash Boys. In this article, the authors analyze five of the most controversial new market practices, including various high‐frequency trading strategies and dark pool activities. They set out a simple conceptual framework based on adverse selection and agency problems, and apply that framework to assess the welfare effects of each of the five practices. While much that is criticized is indeed objectionable, other controversial practices are much more complex than popularly imagined and may in fact be socially desirable. They conclude by evaluating a range of potential reforms to equity market structure. 相似文献

The aim of this paper is to evaluate how immigration of high-skilled workers affects the technological-knowledge bias and, in turn, the skill premium in the host countries, in particular bearing in mind the recent experience in a number of European countries. We study a skill-biased dynamic general equilibrium R&D growth model in which the standard R&D technology is modified so wage inequality results from the direction of the technological knowledge, which in turn is induced by the price channel. By solving the transitional dynamics numerically, we show that the rise of the skill premium arises from the price-channel effect, complemented with a mechanism that reflects the impact of immigration on R&D. According to our quantitative results, our model is able to account for a significant proportion of the dynamics of the skill premium in the data for a number of European countries, thus, suggesting that differences in labour skills between immigrants and natives are, in practice, an important source of skill premium variation over time. 相似文献
