This study investigates how resident support for the development of the demilitarized zone (DMZ) Peace Park incorporates two key components (support and patriotism) as part of the theory of planned behavior (TPB). The results of this study confirm that support is important because it is directly associated with three TPB constructs, and it acts as a mediator between patriotism and the three TPB constructs. Both support and patriotism are statistically significant but different depending on the distance to the DMZ Peace Park. Resident support in the predevelopment stage can possibly extend to behavioral support in the post-development stage. 相似文献

This paper studies the functional specialization of SMEs’ technological competence and its moderating role in the effect of external R&D on their innovative performance. Technological competence consists of many functional dimensions such as basic research, product architecture, process construction, testing, and evaluation, which constitute a sequence of innovation tasks. The specialization of technological competence allows SMEs to utilize economies of specialization in R&D, enhance their bargaining power and appropriability conditions in the process of external R&D, and attract promising R&D partners. However, competence specialization may hamper SMEs’ capabilities to coordinate and integrate diverse external R&D projects. Using a sample of SMEs in Korean manufacturing industries, we find the following results. First, competence specialization positively moderates the effect of external R&D on SMEs’ innovative performance. Second, the positive moderating effect of competence specialization diminishes as the share of external R&D increases. Third, the moderating effect of competence specialization differs across industries depending on the degree of market dominance by a few large firms (i.e., market concentration) and the novelty of technologies pursued by SMEs in each industry. 相似文献

We examine the responses of intraday option-implied volatilities to scheduled announcements of macroeconomic indicators. The increase in implied volatility around macroeconomic news announcements is more pronounced for puts than for calls and is stronger for announcements made during trading hours than for those made during nontrading hours. These effects are also more pronounced in the crisis and postcrisis periods than in the precrisis period. Monetary policy announcements have a more substantial impact on volatility than other announcements have, even after controlling for news surprise components. The impact appears to be greater for policy rate hikes than for policy rate cuts. 相似文献

Labor-management relations have received increasing attention and are believed as important by academics and practitioners. This article examines the key antecedents and outcomes of Korean unionized workers’ perceived labor-management relations. Given the impact on employee performance and corporate productivity, it has not yet been known the extent of dynamics regarding the workers’ perceptions of the labor-management relations. The study employs the structural equation modeling using partial least squares(PLS) technique. The empirical results from 2,632 workers confirm that all hypothesized relationships are significant except the corporate training satisfaction in relation to labor relations. All outcomes of labor relations are significant. This research offers new insights into the important concept of labor-management relations specifically in Korea. Implications and future research are provided. 相似文献

This study explores the asymmetric effects of corporate sustainability strategy on firm value at different conditioning quantiles by performing a dynamic panel quantile regression analysis on global automotive firms from 2011 to 2017. Further, this study measures the distinct effects of positive and negative corporate sustainability strategies on firm value, which has remained unconsidered as yet. The findings suggest that low-value and midvalue firms respond more strongly to positive and negative corporate sustainability strategies than high-value firms. This implies that for low-value and midvalue corporations that are in a growth phase, an investment in positive corporate sustainability strategies is essential to increase firm value by enhancing public perception of their efforts. Therefore, positive corporate sustainability strategy contributes substantially to future growth. Conversely, positive corporate sustainability strategy may not be a priority in increasing firm value for high-value corporations, because these strategies do not enhance the public's discernment of their efforts in ethics management and hence do not contribute to a future increase in value. Meanwhile, engagement in negative corporate sustainability strategy worsens firm value in all quantiles, although the effect is somewhat weaker for high-value firms. Nevertheless, however high valued and well established a firm is, it is not immune to crisis. 相似文献

This research investigates the relationship between a firm's environmental efforts and the sustainability of its competitive advantage by analyzing the effects of change in firm environmental performance on the persistence of profitability growth. We find that environmental resources allow a firm with superior financial performance to sustain its competitive advantage, and also complement the efforts of a poorly performing firm to hasten recovery from inferior financial performance. Our findings further indicate that firms attain such positive effects through enhanced profit margins resulting from improved environmental performance. Additionally, we observe that a corporate strategy of improving environmental performance demonstrates management's responsibility to maximize the shareholder wealth of a well‐performing firm. The results provide valuable insights to align environmental activities towards developing unique resources for sustaining the competitive advantage. The study provides an empirical support for creating economic value by benefiting the environment. Copyright © 2016 John Wiley & Sons, Ltd and ERP Environment 相似文献

This paper examines the informativeness of analysts’ target price forecasts by relating the investment value of target prices to their primary drivers. Decomposing target price forecasts into near‐term earnings forecasts and price‐to‐earnings ratio forecasts, we show that target price revisions reflect information from both components. In addition, we also find that the relative importance of each component in target price revisions is related to firm characteristics. A portfolio based on target price implied expected returns delivers significant abnormal returns. More importantly, we find that the abnormal returns are associated with both earnings and price‐to‐earnings forecasts, which suggests that the informativeness of target price forecasts comes not only from analysts’ ability to forecast short‐term earnings but also from their ability to assess risk and long‐term growth prospect implied in price‐to‐earnings forecasts. 相似文献

This paper comprehensively investigates the effect of government ideology on the type of exchange rate regime that a country implements via multinomial logit and multinomial probit models for 147 countries in the period 1974–2009. Our results clearly indicate that a left‐wing government increases the likelihood that a country implements a flexible regime in the classifications of exchange rate regimes. Nevertheless, evidence is weaker when using the de jure IMF course classification, which is set up by Ilzetzki et al. ( 2008 ). In a deeper investigation, we find that left‐wing governments are more likely to choose a flexible regime relative to a fixed one in our sample of OECD, non‐OECD and non‐Eurozone countries, as the impacts from government ideology on the determinant of the choice of exchange rate regime in Eurozone countries disappear. More importantly, we present many explanations for exchange rate regime choices when macroeconomic conditions, political constraints and institutions impact the choice of exchange rate regime. 相似文献
