This article estimates the price and income elasticities of import and export demands for India, Japan, the Philippines, Sri Lanka, and Thailand using annual time series data. Both price and income elasticities of import demand are found to be in the inelastic range for all five countries. Export demand is found to be price elastic for Japan, the Philippines, and Thailand and price inelastic for India and Sri Lanka. Export demand is found to be income elastic for Japan but not for the other four countries. The Marshall-Lerner-Robinson condition states that a devaluation improves the balance of trade position only if the sum of the absolute values of price elasticity of import demand and the price elasticity of export demand is greater than one. This condition is met for India, Japan, the Philippines, and Thailand but not for Sri Lanka.  相似文献

Mijatovi? and Pistorius proposed an efficient Markov chain approximation method for pricing European and barrier options in general one‐dimensional Markovian models. However, sharp convergence rates of this method for realistic financial payoffs, which are nonsmooth, are rarely available. In this paper, we solve this problem for general one‐dimensional diffusion models, which play a fundamental role in financial applications. For such models, the Markov chain approximation method is equivalent to the method of lines using the central difference. Our analysis is based on the spectral representation of the exact solution and the approximate solution. By establishing the convergence rate for the eigenvalues and the eigenfunctions, we obtain sharp convergence rates for the transition density and the price of options with nonsmooth payoffs. In particular, we show that for call‐/put‐type payoffs, convergence is second order, while for digital‐type payoffs, convergence is generally only first order. Furthermore, we provide theoretical justification for two well‐known smoothing techniques that can restore second‐order convergence for digital‐type payoffs and explain oscillations observed in the convergence for options with nonsmooth payoffs. As an extension, we also establish sharp convergence rates for European options for a rich class of Markovian jump models constructed from diffusions via subordination. The theoretical estimates are confirmed using numerical examples.  相似文献

Careful partner selection is a prerequisite for successful alliances. I posit that institutional distance will influence partner selection in international technological alliances negatively for exploitation, and positively for exploration alliances. A longitudinal dataset of firms in the global tire industry confirms firms’ preference for similar cognitive, normative, and regulatory partners in exploitation alliances, and a preference for dissimilar partners in exploration alliances. However, the latter is true for differences across the regulative and cognitive pillars rather than for normative differences. These findings attest to the antipodal role of institutional differences in the selection of prospective partners for cross-border technological alliances.  相似文献

Anxiety and anger, two frequently experienced emotions during service consumption, arise from different appraisals of the eliciting event, i.e., attribution to uncontrollable circumstances and low coping potential for anxiety versus attribution to providers and high coping potential for anger. These appraisal differences were hypothesized to impact the occurrence of supportive provider responses (higher for anxiety than for anger), and the value given to supportive responses by anxious versus angry customers (higher evaluation for anxiety than for anger). It was also hypothesized that, although evaluation of provider response would mediate the relationship between the intensity of both anger and anxiety and satisfaction with the service encounter as a whole, the power of this mediating effect would be stronger for anxiety than for anger. Hypotheses were confirmed in a survey of air travel passengers reporting episodes of anxiety and anger. Implications of these results for challenges and payoffs involved in the development of adaptive response strategies to anxious and angry customers are discussed.  相似文献

Real-time GDP forecasting, also often known as “nowcasting,” produces estimates for current-quarter real GDP growth, typically based on a centered value from a set of estimates from incoming indicators. These real-time measures are usually intended to be data-based and to not be based on forecaster judgment or add factors. Even so, estimation methodologies in this research area—and prior versions of the system we use—typically have been constrained by using various “fixed” relationships, such as a fixed historical sample horizon and fixed empirical specifications for the indicator variables. This paper describes the methodology, estimation, and software code for a more flexible real-time GDP system that allows the data to decide the best real-time GDP forecast for varying sample horizons and varying specifications for each indicator variable through time. Our system uses data on key indicators as they become available (accounting for the “jagged-edge” nature of the data in the current quarter) to generate an estimate of current-quarter real GDP growth, with weights for combining the indicator-specific estimates as determined by the strength of the indicators’ historical relationships to GDP growth. The improved system searches across a variety of specifications and across sample horizons to choose the best specification as determined by a minimum Schwarz criterion test while also searching for the best sample horizon for minimizing the mean absolute error for a recent prediction period. We illustrate the operation of the system for real-time estimates of real GDP growth over a specific quarter, and examine the properties of the estimates and the implications for predictions. We also discuss potential additional applications and demonstrate a specific application for real-time predictions of the monthly change in payroll jobs.  相似文献

Shopping preferences are affected by the culture in which an individual grows up as well as by individual differences in consumers such as differences in gender, fashion leadership and need for touch. The current study examined the influence of consumers' need for touch and fashion leadership on preference for shopping outlets (e.g. touch and non‐touch shopping channels) between genders and within a particular culture. The purpose of this study was to examine gender, fashion consumer group, need for touch and Korean apparel consumers' shopping channel preference. Participants were a convenience sample of 262 Korean college students who were recruited in Changwon, South Korea. A questionnaire was compiled that included a request for demographic information, the Need For Touch scale, the Measure of Fashion Innovativeness and Opinion Leadership, and items assessing preference for touch and non‐touch shopping channels for clothing. Women and men did not differ in overall need for touch or instrumental need for touch. Fashion change agents and fashion followers did not differ in their preference for touch and non‐touch shopping channels. Preference for touch shopping channels was more greatly affected by variables such as need for touch, gender, and fashion innovativeness and opinion leadership than preference for non‐touch shopping channels. Preference for non‐touch shopping channels was virtually unaffected by the variables examined in the current study. Implications for theory and research are provided.  相似文献

This article examines how the electronic word of mouth (eWOM) information direction (positive vs. negative) and a website's reputation (established vs. unestablished) contribute to the eWOM effect. The article describes a study focusing on the moderating role of the product type (search vs. experience). The results of the experiment show that the eWOM effect is greater for negative eWOM than for positive eWOM, greater for established websites than for unestablished websites, and greater for experience goods than for search goods. The results support the moderating effects of product type on the eWOM information direction-website reputation-eWOM effect relationship. The impact of negative eWOM on the eWOM effect is greater for experience goods than for search goods. Similarly, the impact of website reputation on the eWOM effect is greater for experience goods than for search goods. The findings provide managerial implications for an Internet marketing strategy.  相似文献

Accidents cause major damage for both workers and enterprises in the mining industry. To reduce the number of occupational accidents, these incidents should be properly registered and carefully analysed. This study efficiently examines the Aegean Lignite Enterprise (ELI) of Turkish Coal Enterprises (TKI) in Soma between 2006 and 2011, and opencast coal mine occupational accident records were used for statistical analyses. A total of 231 occupational accidents were analysed for this study. The accident records were categorized into seven groups: area, reason, occupation, part of body, age, shift hour and lost days. The SPSS package program was used in this study for logistic regression analyses, which predicted the probability of accidents resulting in greater or less than 3 lost workdays for non-fatal injuries. Social facilities-area of surface installations, workshops and opencast mining areas are the areas with the highest probability for accidents with greater than 3 lost workdays for non-fatal injuries, while the reasons with the highest probability for these types of accidents are transporting and manual handling. Additionally, the model was tested for such reported accidents that occurred in 2012 for the ELI in Soma and estimated the probability of exposure to accidents with lost workdays correctly by 70%.  相似文献

We report survey results on the currency choice of a random sample of Swedish exporters. We find that for an overwhelming share of exports, the price, invoice and settlement currency is the same. The currency of the customer is the most used, with Swedish kronor and vehicle currencies accounting for approximately equal shares. Currency choice is similar for intra-firm and between-firm trade. We also find that negotiations are important for both the price and for the currency choice. A minority of firms use posted prices for their main exports — the median price adjustment for those firms is once per year.  相似文献

A telephone survey of French- and English-speaking households in Quebec was conducted to obtain information about money management practices, of use information sources and knowledge of personal finance terminology. Correlations and regressions were performed on data from 234 interviews. An index of consumer periodical readership was related positively to variables for female respondent, English-speaking, urban residence, income and education in the correlations. A financial knowledge index was related positively to variables for income, education, and the periodical index in the correlations. The knowledge index peaked for the 41–55 years of age category. A two-equation recursive model for periodical readership and financial knowledge was tested. A regression on the periodical index had positive effects for income, education and variables for age 56–64 and 65 and over, and a negative effect for rural location. A regression on the knowledge index had positive effects for the periodical index, income, French-speaking and the variable for age 41–55, and a negative effect for female respondent. The needs of lower income consumers may not be met well by consumer periodicals. In terms of financial knowledge, English-speaking consumers in Quebec may be at a disadvantage relative to French-speaking consumers with similar income levels.  相似文献

Results of two experiments reveal that the use of probability markers in advertisements affects brand attitude and purchase intentions, and that this is moderated by the type of service, customers’ involvement, and their level of tolerance for ambiguity. Services in the study were classified as more or less hedonic/utilitarian, and more or less involving. Probability markers affect consumers’ brand attitude and purchase intentions for less-involving services, while this effect is not significant for more-involving services. In addition, higher tolerance for ambiguity results in preference of hedges over pledges or no probability markers, while for consumers with lower tolerance for ambiguity the opposite holds. With regards to service type, for more-hedonic, less-involving services the use of hedges in advertising copy increases brand attitude and purchase intentions, while for more-utilitarian, less-involving services pledges result in highest levels of brand attitude and purchase intentions.  相似文献

This article examines the Finnish maritime cluster by identifying the key challenges hindering its competitiveness. The main bottlenecks for the future are concluded to comprise rising cost levels in relation to customer demand, the need for human and capital resources, the need for financial and scientific support for innovation activities, and the lack of contacts and resources when competing for large-scale international projects. These issues are relevant also for the other maritime clusters in the Baltic Sea Region. Thus, joint policies and cooperation in tackling these issues could support the competitiveness of the maritime sector in the whole region.  相似文献

The premise underlying most of the research on strategic consensus is that a higher degree of consensus has a positive impact on organizational performance. Empirical studies, however, have produced inconsistent results for the strength and direction of this relationship, as well as for the role of potential moderators. With this meta-analysis, we provide empirical support for a positive effect of strategic consensus on organizational performance, and offer evidence for the existence of several moderators of the aforementioned relationship, which we then discuss as fruitful avenues for future research. This study enhances our understanding of this important strategy process construct and benefits managerial practice by discussing means for improving the realization and implementation of strategies.  相似文献
