    Abstract: Background: As financial professionals including policy-makers tend to base decisions on research performed using large machine-readable financial databases, the accuracy of the financial data provided by database companies has a direct impact on the quality of their decisions. Objectives: The objective of this study was to examine data errors in the DataGuide and KisValue databases which are both primary sources of stock prices and return data for Korea Exchange securities in Korea. This article also discussed the methodological implications of erroneous data on monthly stock returns in empirical studies on Korean financial markets. Methods: A cross-checking technique was used in this study. Results: The results suggest that there are material discrepancies between the DataGuide and KisValue databases in monthly stock returns, most of which are attributable to the mishandling of split events and of missing values. The results also indicate that DataGuide provides a more reliable service than KisValue in terms of monthly stock returns. Conclusion: The results show that extreme monthly returns resulting from serious data errors in the DataGuide and KisValue databases may be enough to sharply change the properties of monthly stock return distributions and to over- or underestimate long-term abnormal stock returns.

    Abstract: Purpose: Entrepreneurship can offer a competitive advantage to an enterprise through risky decisions that pay off in the development of innovative products, services and markets in a difficult managerial environment and by moving proactively to dominate a competitive market. This study aims to examine the relationship between entrepreneurship and managerial innovation capacity by considering subfactors, such as innovativeness, proactiveness and risk-taking, as well as to explore the relationship between managerial innovation capacity and management performance. The study determines the extent to which policy finance and management support for small and medium-sized enterprises (SMEs) play the role of moderating variables.Design/methodology/approach: Data collection was carried out in 820 SMEs. To verify the hypotheses, Covariance Structure Analysis was conducted using EQS6b.Findings/results: The findings indicate that entrepreneurship has a significant influence on strategic planning, research and development, and technology commercialisation. This study found that managerial innovation capacities have positive effects on management performance. In addition, this study confirmed that when entrepreneurship affects managerial innovation activities, policy financial support and management support serve as moderators.Practical implications: Small and medium-sized enterprises should enhance their innovation capacity and expand innovative entrepreneurship and policy finance to achieve competitiveness, survive and show continuous development and growth in a changing environment.Originality/value: The study provides SMEs with information they can use to increase their awareness of internal managerial innovation activities, which are the original sources of competitive advantage, and help promote research and development (RD) and organizational management for continuous reinforcement of innovation capacity. the study provides SMEs with information they can use to increase their awareness of internal managerial innovation activities, which are the original sources of competitive advantage, and help promote RD and organizational management for continuous reinforcement of innovation capacity.
