Abstract

Previous studies that were concerned with the impact of depreciation of the ringgit on the Malaysian trade balance employed data either between Malaysia and rest of the world or between Malaysia and each of her major trading partners. Specifically, the bilateral trade balance between Malaysia and the US is shown to be insensitive to the real bilateral ringgit–dollar rate. In this article we wonder if disaggregating trade flows between Malaysia and the US by commodity could help us to discover any significant effects that the real exchange rate could have. We consider 101 industries that export from US to Malaysia and 17 industries that import from Malaysia. While majority of the industries showed short-run sensitivity to the real bilateral exchange rate, short-run effects lasted into the long run almost in half of the industries in both group.  相似文献

Abstract

We show that the strong version of the purchasing power parity (PPP) hypothesis holds in most of the US dollar real exchange rates using cointegration method that accounts for breaks in the models. The break dates in seven of the Asian currencies coincide with the two rounds of currency depreciation recorded during the 1997–1998 financial crises. We obtain a mean half-life estimate of about 10 months for PPP to converge to its long-run equilibrium level. Our confidence intervals based on persistence profile approach for the half-lives is much narrower than previous evidence might indicate. Taken together, these results show that mean reversion is stronger than commonly thought.  相似文献

This study analyzes the relationship between perceived risk, evaluation, satisfaction, and behavioral intention of tourists attending a local festival. Based on a survey with a sample of 465 respondents attending a local festival in South Korea, a structural equation model (SEM) is proposed that involves festival-related perceived risk, perceptual evaluation, overall satisfaction, and behavioral intention for future attendance at this and other festivals. Firstly, the results show that while risk may lead to a negative perception of a festival, it has no effect on satisfaction or subsequent behavioral intention. Secondly, the results show that direct causality exists between perception, satisfaction and future intention. Thirdly, a demand for diversity in programs determines perceptions of risk, which in turn permits a segmentation of visitors based on these characteristics. The findings of this study contribute to successful planning and marketing strategies to meet the demands of psychologically segmented tourists, especially in festival studies.  相似文献

This study investigates the structural relationships among responses to website advertisements, website attitudes, brand attitudes, and purchase intentions in the case of web advertisements for casual-dining restaurants. Responses toward advertising (Rad) factors were categorized as cognitive responses and affective responses. The SEM model in LISREL was used to examine the interrelationships among the proposed hypothesized constructs. Several empirical results were obtained. First, Rad had a positive effect on website attitudes. Second, website attitudes had a positive effect on brand attitudes. Third, brand attitudes had a positive effect on purchase intentions. Finally, some discussion and implications of the study are provided.  相似文献

The objectives of this study are to explore the food-related lifestyle segments of the mature market, to identify its socio-demographic characteristics, and to investigate the differences in their attitudes toward Home Meal Replacement (HMR). A survey was conducted of adults 55 years of age and older living in Seoul, South Korea. Out of the 600 distributed questionnaires, 361 were retained for final analysis, which is a response rate of 60%. Cluster analysis identified five consumer segments. Significant differences were found among the five segments in terms of socio-demographic characteristics and attitudes toward HMR. This study shows operators of HMR the patronage motives and attributes that each segment values when considering HMR.  相似文献

We investigate the effects of technology, entrepreneurial, market, and learning orientations on firm innovativeness, and the mediating effect of firm innovativeness on these relationships, using a survey of 374 small- and medium-size enterprises in Korea. The results reveal that, while technology, entrepreneurial, and learning orientations significantly influence firm innovativeness, firm innovativeness has a significant effect on firm performance. We also find that firm innovativeness has a statistically significant mediating role in the relationships of technology, entrepreneurial, and learning orientations to firm performance. Our study contributes to strategic management and emerging market literature by identifying the pivotal role of innovativeness for firms that seek to benefit from various types of strategic orientations.  相似文献

A technology roadmap (TRM) links technologies with a company's strategic objectives and so supports acquisition of required technologies in advance of needs. It is a powerful tool for strategic planning and technology management. Because technology is changing rapidly and market competition is fierce, the role of a TRM is becoming increasingly important. To support the role of a TRM, many firms and governments that use roadmapping are becoming interested in reducing costs while retaining objectivity during TRM development. One suggestion to achieve these goals is to use the keyword‐based quantitative approach to creating a TRM, but the information provided by the approach is limited because of the characteristics of keyword information. To solve this limitation, this research uses the concept of ‘function’ to support quantitative analysis for developing a TRM. The concept of function can provide information on the uses and purposes of a technology. To represent a function, a subject–action–object structure is commonly used. The suggested approach allows research and development (R&D) managers to extend the views of product and technology during development of a TRM. In addition, by reducing the time required to develop a TRM, the proposed approach supports quick and accurate decision‐making by R&D managers.  相似文献

In this paper, we empirically investigate how greenness information is priced in the green bond market. Our comparison of liquidity-adjusted yield premiums of green bonds versus synthetic conventional bonds indicates that, on average, there is no robust and significant yield premium or discount on green bonds. However, green bonds certified by an external reviewer enjoy a discount of about 6 bps. Furthermore, green bonds that obtain a Climate Bonds Initiative certificate show a discount of around 15 bps. The findings suggest that a universally accepted greenness measure can benefit the development of the green bond market.  相似文献

Adverse weather is the dominant cause of delays in the National Airspace System (NAS). Since the future weather condition is only predictable with a certain degree of accuracy, managing traffic in the weather-affected airspace is a challenging task. In this paper, we propose a geometric model to generate an optimal combination of ground delay and route choice to hedge against weather risk. The geometric recourse model (GRM) is a strategic Probabilistic Air Traffic Management (PATM) model that generates optimal route choice, incorporating route hedging and en-route recourse to respond to weather change: hedged routes are routes other than the nominal or the detour one, and recourse occurs when the weather restricted airspace becomes flyable and aircraft are re-routed to fly direct to the destination. Among several variations of the GRM, we focus on the hybrid Dual Recourse Model (DRM), which allows ground delay as well as route hedging and recourses, when the weather clearance time follows a uniform distribution. The formulation of the hybrid DRM involves two decision variables - ground delay and route choice - and four parameters: storm location, storm size, maximum storm duration time, and ground-airborne cost ratio. The objective function has two components: expected total ground delay cost and expected total airborne cost. We propose a solution algorithm that guarantees to find the global optimum of the hybrid-DRM. Based on the numerical analysis, we find that ground-holding is effective only when combined with the nominal route. Otherwise, it is optimal to fly on the route determined by the DRM without ground delay. We also find the formula of the threshold ground-airborne cost ratio, which we call the Critical Cost Ratio (CCR), that determines the efficacy of ground delay: the higher the CCR, the more effective the strategies involving ground delay. We conclude that both ground delay and route hedging should be considered together to produce the best ATM decisions.  相似文献
