Adopting homothetic variable returns to scale functional specifications, this study identifies the returns to scale in the
aggregate production functions of four East Asian newly industrialized economies–Hong Kong, Korea, Singapore, and Taiwan–and
the Group of Five economies based on a maximum likelihood estimation. The study finds evidence of increasing returns in the
early developmental stage of the East Asian economies. Separating out the scale contribution from the non-scale factor contributions,
the decomposition of the sources of East Asian economic growth differs significantly from the conventional constant returns
to scale results, indicating that the role of technical progress is overestimated when constant returns to scale is assumed. 相似文献

Owing to global warming, ice in the Arctic Ocean has shrunk by 2.7% every 10 years since 1978, resulting in tremendous damage. This study uses the Cobb–Douglas production function to analyze the impact of abnormal weather on energy industry production using temperature and precipitation indicators. In particular, the government identified the impact of abnormal weather conditions on manufacturing and public works related to the Korean energy industry. The results showed that the numbers of freezing days and heavy rain days adversely affect public works, whereas hot and cold days and heavy rain days all positively affect the production of coal, petroleum, and chemical products. These results also led to regional risk assessments of the energy industry. This study can help in developing the 2030 industry climate change adaptation plan. 相似文献

This study examines if informed trading is present in the index option market by analyzing the KOSPI 200 options, the most actively traded derivative product in the world. The spread decomposition model developed by Madhavan, Richardson, and Roomans (1997) is utilized and the adverse‐selection cost component of the spread estimated by the model is then used as a proxy for the degree of informed trading. We find that adverse‐selection costs constitute a nontrivial portion of the transaction costs in index options trading. Approximately one‐third of the spread can be accounted for by information asymmetry costs. A further analysis indicates that adverse‐selection costs are positively related with option delta. Our regression analysis shows that option‐related variables are significantly associated with estimated information asymmetry costs, even when controlling for proxies for informed trading in the index futures market. Finally, we find the evidence that foreign investors are better informed compared to domestic investors and that domestic institutions have an edge in terms of information over domestic individuals. © 2008 Wiley Periodicals, Inc.

An important question for manufacturers relates to how to conduct exchanges with suppliers when the interaction is done in an uncertain environment. Existing literature suggests the use of unilateral control (i.e., vertical control over the supplier) to reduce the negative effects of environmental uncertainty, whereas recent research on relational norms suggests bilateral control mechanisms (i.e., the norm of information sharing) as an alternative. We propose that in order to secure satisfactory performance from suppliers, manufacturers rely on different control mechanisms depending upon the level of environmental uncertainty on one hand, and the nature of interdependence in the manufacturer-supplier relationship on the other. Our empirical results based on 162 manufacturers indicate the following: 1) manufacturers' reliance on vertical control increases as environmental uncertainty and power asymmetry increase; 2) by contrast, reliance on the bilateral information sharing increases as interdependence magnitude increases and as environmental uncertainty decreases; 3) suppliers' performance, as perceived by manufacturers, increases with the use of bilateral information sharing. 相似文献

This study uses a sample of 39 025 urban families from the 1996 Korean Family Income and Expenditures Survey to examine the relationship between family characteristics and expenditure on convenience foods. Results indicate that age and education of the family's head, number of children, presence of children under the age of six, the wife's labour force participation, and area of residence were significant in predicting the level of expenditure on convenience foods. The present study points to and gives a rationale to differences in some of the effects as compared with those found in Western countries. 相似文献

This paper focuses on the problem of analyzing how factors impact hunger across states when hunger is ill-defined. Hunger
(which is a latent variable) is presumed to depend on macroeconomic, legislation, policy, and demographic variables. Based
on the Bayesian method of a posterior odds ratios, we find that the high school graduation rate appears to be the single most
important factor we identify which affects the perceived hunger measure.

Using the high‐quality intraday transaction data from 2001–2012, we investigate changes in stock market liquidity in response to the monetary policy announcements of the Bank of Korea (BOK). We find that liquidity impairment associated with informed trading occurs prior to the announcements but it disappears subsequent to the global financial crisis. In addition, liquidity impairment appears to become more severe with insufficient experts' predictability and accuracy rather than with policy rate change itself and unscheduled announcements. Finally, the Federal Open Market Committee (FOMC) announcements, changes in the Volatility Index (VIX), and trading by foreign investors play a limited role in explaining stock market liquidity changes. Overall, results indicate that central bank communication plays a significant role in reducing liquidity impairment by enhancing the predictability of policy actions, and therefore, mitigating information asymmetry. 相似文献

Referral reward programs have been shown in past research to stimulate referrals and also to contribute positively to customer lifetime value and firms’ profitability. In this paper we examine whether, how, and under what conditions providing a reward for a referral affects receivers’ responses to the referral. Based on a multiple motives inference framework, we propose that rewards adversely affect responses because they lead receiving consumers to infer ulterior motives for the referral. Using experiments and a survey, we find support for this hypothesis and show that this effect is stronger for unsolicited and weak tie referrals. We also demonstrate that rewarding both the referral provider and receiver or providing symbolic rewards can eliminate the negative effect of rewarded referrals. The paper makes conceptual contributions to the literature on referral reward programs, word-of-mouth, and motive inferences. The work has implications for managers considering ways to construct referral programs and design marketing activities to increase referrals. 相似文献
