Most small and medium enterprises (SMEs) in Korea struggle in financing R&D. Thus, the Korea Core Industrial Technology Investment Association (KITIA) was established to implement a matching fund program (MFP) to help SMEs with this undertaking. Applicant firms to the MFP are reviewed first based on their technology levels and are required to attract financing from venture capitalists (VCs), before receiving funds from the MFP. This paper, based on KITIAs MFP applicant data from 2001 to 2004, evaluates the performance of the MFP in terms of the success rate of funded SMEs’ initial public offerings (IPOs) and bankruptcy rates in relation to those SMEs that could not attract matching funds. Propensity score matching was used to eliminate selection bias from the data in order to assess the actual treatment effect of the MFP. According to the result of logistic regression applied to the matched data, MFP apparently did not have significant effects on IPO success and bankruptcy. This implies that MFP needs to allow VCs more time to evaluate SMEs covering qualitative aspects as well. It is expected that this change of structure can provide better performance of MFP in terms of IPO success and bankruptcy of matched SMEs. 相似文献

Two experiments were conducted to evaluate the effectiveness of two online persuasion claims: limited product availability (e.g., only 3 items left) and product popularity (e.g., 94% of consumers bought this product after viewing this site). The popularity claim appeared to enhance quality perception, particularly among highly risk-averse consumers, and purchase intention. We attribute these findings to the quality signaling effect and the bandwagon effect of the claim. On the other hand, the limited availability claim exerted no influence: low message credibility and the lack of psychological reactance are deemed to be possible reasons for the insignificant effect of the claim. 相似文献

The goal of this study was to identify and examine the various factors affecting adolescents' body‐tanning behaviours. Gender, body mass index (BMI), sociocultural attitudes towards appearance (SATA) and body satisfaction were examined in order to determine how these variables influence both outdoor sun‐tanning and indoor tanning‐bed use. Self‐administered survey data were collected from 155 adolescent boys and 202 adolescent girls with an average age of 14.3. Multivariate analysis of variance and multiple regression methods were used to analyse the data. Adolescent girls tended to engage in both outdoor and indoor tanning. Overall, adolescents' SATA significantly affected their body‐tanning behaviours. However, BMI and body satisfaction revealed a significant effect only on indoor tanning behaviour. Implications for the design of interventions and overall health promotion towards adolescents are discussed with suggestions for future research. 相似文献

We aim to compare the activities of the two main credit guarantee institutions in Korea. There has been mounting criticism that although these institutions were mandated to play different roles in financing small and medium‐sized enterprises (SME), their operations are, in fact, similar, and many SME receive overlapping support from both institutions. Using the propensity score matching method (allowing for multiple, mutually exclusive support scenarios) to compare the effects of PCG on different institutions, the present study provides suggestions to help the government make decisions regarding the consolidation of PCG funds. The results suggest that the institutions function differently and target different SME. However, overlapping support enables firms to expand their sales only, indicating the existence of inefficiency in the case of overlapping support to firms. 相似文献

This study investigates the association between discretionary accruals and Big Six and non-Big Six auditors, and the direction of auditor change. We hypothesize that there is no significant difference in discretionary accruals between Big Six and non-Big Six clients when there is low incentive for auditors to provide high-quality audits, as in Korea.Upon examination of the discretionary accruals of firms listed on the Korean Stock Exchange from 1994 to 1998, we find there is no significant difference between the discretionary accruals of firms with Big Six and non-Big Six auditors. This holds true for firms that switch from non-Big Six to Big Six auditors and vice versa. These resources imply that there may be no difference in audit quality between Big Six and non-Big Six auditors in Korea. This is consistent with other studies in Korea, while inconsistent with the findings of previous studies on audit quality in other countries. 相似文献

The principal result of this paper is the demonstration of a method for measuring an index of (e.g.) nominal GNP over extended periods of time and the inequality thereof. ‘Snap shot’ inequality for specific points in 1964, 1972 and 1980 is also reported and decomposed for six subgroups in 122 countries. 相似文献

This article presents a qualitative analysis method based on fuzzy relations for a cross-impact model designed for a technology impact assessment. The cross-impact knowledge is often uncertain or fuzzy when dealing with future events. Assessing the cross-impact relationships among future technologies creates a more uncertain or fuzzy situation because of the time and the uncertainty involved in evaluating future technologies. In addition, experts prefer to use linguistic terms or fuzzy values in their predictions. Thus a cross-impact matrix is represented as fuzzy relations on causal concepts. We therefore develop inference algorithms based on fuzzy relations and show a simple technology assessment example to illustrate this approach. This approach is useful in finding the key technology because it considers not only the direct impact but also the indirect impact. 相似文献

This paper suggests a technology forecasting approach based on a semi-Markov model, which appropriately describes the probabilistic nature of a sequential technology development process. This approach focuses primarily on the utilization of the information that has been skipped in conventional Delphi survey data. That is, through a simple statistic, the interrelationships among sequential technology developments can be extracted in a formal structure of a semi-Markov model from the original Delphi panel's estimates. A simulation technique is developed to forecast the development process by utilizing the information on such interrelationships. This technique provides a flexible and useful tool for R&D planners or project managers, especially in postanalysis of Delphi forecasting. To make good use of the approach, a computer-based interactive Delphi data analysis system (IDEAS) is implemented in IBM PC. 相似文献
