Rotating savings and credit association (ROSCA) is a well-known microfinance association widely used in many countries around the world with long histories. By considering extra profits that such a system can provide when compared to banking transactions, we develop optimization problems to achieve an optimal design of a ROSCA. We find that ROSCAs might attract investors when deposit and loan rates from formal banking systems are not favorable. Furthermore, optimal rates and optimal orders to maximize system outputs are reported. 相似文献
The food truck industry has become a national phenomenon in the United States by gaining attention and praise. However, there has been limited attention on how and why consumers decide to patronize food trucks. The purpose of the study is to investigate determinants of consumers’ intention to patronize food trucks by applying the model of goal-directed behavior. Structural equation modeling was employed to assess the relationships among constructs in the proposed research model. This study contributes significant theoretical and practical implications by first attempting to examine what specific psychological variables influence the decision-making process regarding consumers’ intention to visit food trucks. 相似文献
This study examines important but understudied issues in the servitization of global manufacturing firms. We begin with a review of the literature that suggests that global manufacturing firms can grow by integrating services into traditional products in a rapidly changing business environment. We fill a gap in the literature by considering exogenous (i.e., country-level and industry-level) and endogenous (i.e., firm-level) antecedents of servitization. We posit that home-country institutional development has a positive effect on global manufacturing firms’ servitization. We also posit that a high level of industry competition is favorably associated with servitization and that a firm’s technological capability and geographic diversification are related to servitization. To test these arguments, we made a comprehensive data set by using the Thomson Reuters database, which provides the financial information of 301 global manufacturing firms in the 2015 Forbes Global 1,000, and by using annual reports published on the websites of the firms.
Transformational leadership has received growing attention in leadership studies. However, open questions remain concerning its operationalization and its universal effectiveness. Drawing on transformational leadership theory and leadership contingency theory, this study explores these issues in an Asian context. Survey responses from 491 employees working for foreign subsidiaries in Korea were analyzed. Given their multi-dimensionality, transformational leadership behaviors were framed as a two-dimensional structure: organization-related behaviors (OBs) and person-related behaviors (PBs). Findings showed that both OBs and PBs were mediated by psychological empowerment to determine organizational commitment. More importantly, the findings indicated that the empowering process driven by both leadership behaviors is contingent on organizational structure. Specifically, centralization negatively moderated the empowering process of PBs. Formalization positively moderated the empowering process of OBs and negatively moderated that of PBs. These findings have noteworthy value by virtue of quantitatively revealing the organizational structure wherein the empowering process of transformational leadership behaviors is effectively induced in South Korea. Based on the results, significant theoretical and managerial implications are discussed. 相似文献
In this paper, we explore the features of a structural credit risk model wherein the firm value is driven by normal tempered stable (NTS) process belonging to the larger class of Lévy processes. For the purpose of comparability, the calibration to the term structure of a corporate bond credit spread is conducted under both NTS structural model and Merton structural model. We find that NTS structural model provides better fit for all credit ratings than Merton structural model. However, it is noticed that probabilities of default derived from the calibration of the term structure of a bond credit spread might be overestimated since the bond credit spread could contain non-default components such as illiquidity risk or asymmetric tax treatment. Hence, considering CDS spread as a reflection of the pure credit risk for the reference entity, we calibrate it in order to obtain more reasonable probability of default and obtain valid results in calibration of the market CDS spread with NTS structural model. 相似文献
Asset management and pricing models require the proper modeling of the return distribution of financial assets. While the return distribution used in the traditional theories of asset pricing and portfolio selection is the normal distribution, numerous studies that have investigated the empirical behavior of asset returns in financial markets throughout the world reject the hypothesis that asset return distributions are normally distribution. Alternative models for describing return distributions have been proposed since the 1960s, with the strongest empirical and theoretical support being provided for the family of stable distributions (with the normal distribution being a special case of this distribution). Since the turn of the century, specific forms of the stable distribution have been proposed and tested that better fit the observed behavior of historical return distributions. More specifically, subclasses of the tempered stable distribution have been proposed. In this paper, we propose one such subclass of the tempered stable distribution which we refer to as the “KR distribution”. We empirically test this distribution as well as two other recently proposed subclasses of the tempered stable distribution: the Carr–Geman–Madan–Yor (CGMY) distribution and the modified tempered stable (MTS) distribution. The advantage of the KR distribution over the other two distributions is that it has more flexible tail parameters. For these three subclasses of the tempered stable distribution, which are infinitely divisible and have exponential moments for some neighborhood of zero, we generate the exponential Lévy market models induced from them. We then construct a new GARCH model with the infinitely divisible distributed innovation and three subclasses of that GARCH model that incorporates three observed properties of asset returns: volatility clustering, fat tails, and skewness. We formulate the algorithm to find the risk-neutral return processes for those GARCH models using the “change of measure” for the tempered stable distributions. To compare the performance of those exponential Lévy models and the GARCH models, we report the results of the parameters estimated for the S&P 500 index and investigate the out-of-sample forecasting performance for those GARCH models for the S&P 500 option prices. 相似文献
A potentially important side effect of quantitative easing (QE) by the United States Federal Reserve was the expansion of capital flows into developing countries. As a result, there were widespread concerns that reversing QE might trigger financial instability in those countries. The central objective of our article is to empirically investigate this important issue by (1) examining the effect of QE on capital flows into developing Asia and (2) identifying the most significant factors that influence the effect of a QE taper tantrum on exchange rate instability. We find that capital flows into developing countries during QE were at least comparable to those before the global financial crisis. We also find that capital flows during QE and the symptoms of those capital flows such as high inflation, credit expansion, and the deterioration of the current-account balance accounted for much of the destabilizing effect of a QE taper tantrum. While there is no evidence that macroprudential policies directly reduce the destabilizing effect, they can nevertheless be useful preemptive measures. 相似文献
Researchers have focused on the group-level leader-member exchange (LMX) differentiation in order to develop a more comprehensive view of within-group variability of LMX. Although the group-level LMX differentiation has been thought to have significant impacts on both individual and group outcomes, we know little about what makes leaders have differential relationships with their members. Drawing on both motives theory and interpersonal interaction theory, we examined the antecedents of LMX differentiation in a sample of 94 group leaders and 553 members of design companies in South Korea. Results indicated that whereas leaders high in affiliation motives had less differential relationships, leaders high in power motives had more differential relationships. We also found that the negative relationship between leaders’ affiliation motives and LMX differentiation was stronger when members’ affiliation and power motives were higher. Theoretical and practical implications are discussed. 相似文献
The purpose of this study was to identify the underlying structures of RV traveler’s pull factors to campgrounds and confirm the results by using exploratory factor analysis and confirmatory factor analysis with multiple data sets. The results identified the following five dimensions of the campground traveler’s key attributes: Activity, Amenity, Essentials, Price, and Store. The “Essentials” factor had a grand mean of 4.47, which was the highest among the five factors. Therefore, campground owners and managers should pay extra attention to maintaining a high quality on those essential attributes first, before considering adding or promoting any other items. 相似文献
