We introduce a new numerical method called the complex Fourier series (CFS) method proposed by Chan (2017) to price options with an early-exercise feature—American, Bermudan and discretely monitored barrier options—under exponential Lévy asset dynamics. This new method allows us to quickly and accurately compute the values of early-exercise options and their Greeks. We also provide an error analysis to demonstrate that, in many cases, we can achieve an exponential convergence rate in the pricing method as long as we choose the correct truncated computational interval. Our numerical analysis indicates that the CFS method is computationally more comparable or favourable than the methods currently available. Finally, the superiority of the CFS method is illustrated with real financial data by considering Standard & Poor’s depositary receipts (SPDR) exchange-traded fund (ETF) on the S&P 500® index options, which are American options traded from November 2017 to February 2018 and from 30 January 2019 to 21 June 2019. 相似文献

The earnings premium for education, and higher education in particular, is well documented. This article examines the college achievement gap between students coming from positions of high and low socio-economic status. Other papers have also looked at this issue, often by employing, at least in part, an Oaxaca decomposition. Past papers artificially divided socio-economic status into binary groups of high and low, in order to employ the decomposition. Socio-economic status is innately a continuous variable. Therefore, we implement a continuous version of the Oaxaca decomposition. Higher socio-economic students are both slightly better prepared in terms of observable characteristics and have better returns to their characteristics than lower socio-economic students. Notable differences across results obtained from the binary and continuous decomposition methods are discussed. 相似文献

In this pedagogical contribution the authors extend the traditional three-class tariff employed in the French passenger railway system with the more resonant story of the service quality variations associated with the three passenger classes of the ill-fated RMS Titanic. In doing so, they provide economics instructors with an opportunity to integrate the well-known motion picture Titanic (Cameron and Landau 1997) into the teaching of economics. This article provides instructors with resources that can be used to link historical and modern travel examples of price discrimination in order for students to reach a “deeper understanding of course concepts” (Salemi 2002, 725). 相似文献

ABSTRACTAlumni communication is vital in sustaining the relationship between alumni and their alma maters. This research investigated four cohorts of alumni, and their intentions to use a range of traditional and digital communication channels, including social media. An online questionnaire was sent to 8060 alumni and resulted in 595 usable responses, yielding a 7% response rate. The research results showed that alumni have the highest intentions to use the alumni e-newsletter and the alumni Website and the lowest intentions to use social media, e.g., Twitter, Instagram, and YouTube. Among alumni cohorts, significant statistical differences in their intentions to use these communication channels were identified. Given our findings, alumni communication staff are encouraged to leverage different communication channels targeting alumni in different age groups. 相似文献

ABSTRACTThe bottom of the pyramid (BOP) market has gained importance in international entrepreneurship due to its large market potential. Drawing on the literature of international business education, as well as social entrepreneurship and international entrepreneurship education, we propose a course to educate students how to develop business intimacy with the BOP community. We employ the experiential-learning pedagogical framework and design elements including a short-term study abroad service trip, an entrepreneurship project, and structured reflections. Using both qualitative and quantitative data, we demonstrate that the course facilitates students’ learning in the key areas of international and social entrepreneurship, including the economic and social value of community embeddedness for BOP ventures, the emotional intelligence in interacting with BOP communities, and the attitude toward social entrepreneurship. 相似文献

Are museums, galleries and cultural institutions (MGC) educational institutions or accommodations of leisure market? The aim of the present study is to understand why people visit MGCs through analysing a potential link between internet use types and MGC visits. Internet use is categorized into three types: independent activities, recreational activities and social activities. The empirical results indicate that internet use for recreational activities is negatively related to MGC visits, while internet use for independent activities is positively related to MGC visits. The findings suggest that MGCs are expected to provide visitors with educational experience rather than with social or recreational experience. 相似文献

Finite mixtures offer a rich class of distributions for modelling of a variety of random phenomena in numerous fields of study. Using the sample interpoint distances (IPDs), we propose the IPD‐test statistic for testing the hypothesis of homogeneity of mixture of multivariate power series distribution or multivariate normal distribution. We derive the distribution of the IPDs that are drawn from a finite mixture of the multivariate power series distribution and multivariate normal distribution. Based on the empirical distribution of the IPDs, we construct a bootstrap test of homogeneity for other multivariate finite mixture models. The IPD test is applied to mixture models for matrix‐valued distributions and a test of homogeneity for Wishart mixture is presented. Numerical comparisons show that IPD test has accurate type I errors and is more powerful in most multivariate cases than the expectation–maximization (EM) test and modified likelihood ratio test. 相似文献

Since the 1990s, firms in Japan have reduced their human capital investment in the workplace to minimize costs. Moreover, in response to the increase in the number of non-regular employees and turnover rates, workers need to have greater incentive to make the self-motivated investment in themselves for their self-protection. In this study, we first estimate the effects of workers’ self-motivated investment in themselves on wage rates. Next, we explore who is likely to participate in which training type and accordingly estimate the effects of the self-motivated investment on wage rates by training type. Our estimates controlling for individual-level fixed-effects indicate that the return is significantly positive and particularly high for practical training related to workers’ current jobs, and regular workers tend to self-select these higher-returns programs, while non-regular workers are more likely to enroll in lower-returns programs, such as schooling. This trend in investment in oneself could potentially increase the wage inequality between regular and non-regular workers through the self-selection of training types. Our estimates reveal that receiving the training and education benefit raises the likelihood for workers to participate in a high-return training program regardless of whether they are non-regular or regular workers. This suggests that government benefits on self-investment change workers’ self-selection of training type and serve to promote practical trainings that lead to high returns. 相似文献

This paper explores the relative influence of the accounting academy and accountancy professional associations in the debate concerning the profile and quality of accounting education research. This research analyses 13 semi-structured interviews undertaken with members of key accounting professional associations in Australia, New Zealand (ANZ) and the United Kingdom and Ireland (UKI). The paper makes a theoretical contribution by the novel application of the institutional logics theory to the literature concerning professional accounting associations (PAAs) demonstrating the dominant commercial logic of the education function and the more traditional fiduciary logic of the technical function. The research finds that the primary stakeholders in the professional accounting curriculum development model are the PAAs and employers, whilst the accounting academy is relatively absent. The relative independence of the education and research and technical functions within PAAs is also identified: academic research and technical activity has little influence on professional education and vice versa. However, PAAs’ funding of academic research is common across all four countries for brand recognition and in some instances to influence policy rather than informing the professional curriculum. 相似文献

This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change. 相似文献
