本文对韩国国内行政区域如市郡区等小地区的失业统计共同差额比进行推定的方法有联合推定量,Woolf推定量和Mantel-Haenszel推定量等。对这个推定量的可信度是通过偏差和平均平方误差的概念来进行比较的。从对京畿地区经济活动人口调查情况看,这个地区内的24个市郡单位行政自治地区的男、女失业率差额比的偏差及平均平方误差是通过本次研究提出的推定程序来推定的。这些推定数的稳定性和效率性可以通过相对偏差和相对平均误差平方根来评价。Woolf推定量或Mantel-Haenszel推定量比联合推定量更为稳定,从其效率性来看三者很相似。 相似文献

The conventional dividend–price ratio is highly persistent, and the literature reports mixed evidence on its role in predicting stock returns. We argue that the decreasing number of firms with a traditional dividend‐payout policy is responsible for these results, and develop a model in which the long‐run relationship between the dividends and stock price is time varying. An adjusted dividend–price ratio that accounts for the time‐varying long‐run relationship is considerably less persistent. Furthermore, the predictive regression model that employs the adjusted dividend–price ratio as a regressor outperforms the random‐walk model. These results are robust with respect to the firm size. 相似文献

Using a cross‐cultural conceptualization with a targeted sample of Americans and Koreans, it was noted that Koreans exhibited more responsible financial management behavior than Americans after controlling for locus of control, financial knowledge, and income interactions. Overall, financial knowledge was positively related to responsible financial behavior. No direct effects on financial management behavior were noted for locus of control or household income. Locus of control was found to mediate the effect of financial knowledge on financial behavior for Koreans. Being Korean did moderate between financial knowledge and financial behavior. 相似文献

Previous published studies have estimated the long‐run cointegrating relationship to infer the price elasticity of imports, but a stable long‐run cointegrating relationship might not be detected in the data, especially in the case of sectoral data. This paper develops a method to estimate the price elasticity of imports based on a vector autoregression model, which can be applied when a stable long‐run cointegration relationship does not exist. The methods developed in past studies and our method are applied to Korean sectoral imports data to illustrate the usefulness of our method. 相似文献

This paper examines the redistributive effects of Korea's fiscal policies, including consumption taxes and in‐kind benefits. Using the Household Income and Expenditure Survey of 2007, we find that taxes and transfers reduce income inequality in Korea by 13.8 percent. Contrary to the popular belief that direct taxes are the key tool for redistribution, in‐kind benefits, direct taxes, and social security contributions all decrease the Gini coefficient by 6.7, 4.7, and 2.9 percentage points, respectively. The redistributive effect of consumption taxes is small and negative (?0.5 percentage point). Policy simulations indicate that education spending financed by the personal income tax has a positive redistributive effect and that the lower 70 percent of households enjoy positive net benefits. Spending targeting the poor has a strong redistributive effect, which implies low popularity because the majority of households face net losses. 相似文献

Using both quantity‐ and price‐based measures of financial integration, the paper shows an increasing degree of financial openness and integration in emerging Asia. Assessing the impact of a regional shock relative to a global shock on local equity and bond markets, the findings suggest that the region's equity markets are integrated more globally than regionally, although the degrees of both regional and global integration have increased significantly since the 1997/1998 Asian financial crisis. However, emerging Asia's local currency bond markets remain generally segmented, being neither regionally nor globally integrated. There are potential benefits from increased regional integration of financial markets. Financial integration at the regional level allows for the region's economies to benefit from allocation efficiency and risk diversification. Policymakers in the region must strike the right balance between maximizing the net benefits from regional and global financial openness, and minimizing the potential costs of financial contagion and crisis. 相似文献

A new trend in corporate planning is to exploit uncertainty by taking investment opportunities as real options. This options approach is to complement the conventional net present value (NPV) criterion in evaluating risky investments. In this paper, we take a broad look at the real options approach to various engineering economic decision problems, laying out how it provides an immediate and important perspective on value creation in an uncertain world. Unlike financial options, real options analysisdeals with investments in real assets, which is one of the primary interest areas in engineering economics. For that reason, we believe that any advancement in the real options decision framework will benefit the field of engineering economics. 相似文献

This study proposes two models of addictive buying behaviour. The first model assumes that childhood experiences of parental discord influence depression and low self-esteem which, in turn, increase addictive buying behaviour in adulthood. The data were obtained from questionnaires completed by 149 subjects (college students, Chicago residents, and members of Debtors Anonymous). Testing the first model indicates that parental discord is indeed positively related to depression and addictive buying, and that depression is related negatively to self-esteem and positively to addictive buying. The second model indicates that addictive buying is positively related to depression and low self-esteem. 相似文献

Cliometric approaches to the economic history of Korea have emerged as a distinctive trend from the mid‐1990s. They have quickly made profound changes to our understanding of Korea's economic history from 1700 to 1945. The most remarkable include identifying the long‐term decline of agricultural productivity from around 1800, the subsequent upswing in economic development from the late nineteenth century, and the continuing growth during the Japanese colonial era, 1910–45. We survey primarily the Korean language literature that reports the achievements of this cliometric movement and speculate about the future research agenda. 相似文献
