This study fills an important gap in the literature by exploring the effects of the attractiveness of a non-monetary promotion with premiums on credit card purchase intention and brand selection. Two experimental studies involving 386 undergraduates were done. Non-monetary sales promotions with attractive premiums have a positive influence on the credit card purchase intention, compared to non-monetary sales promotions with unattractive premiums. On brand choice, non-monetary sales promotions with attractive premiums increase the likelihood of brand choice promoted. Premiums attractiveness is an important variable in the evaluation of a promotional offer that aims to increase the intention purchase and motivate the selection of brand. This study helps managers in choosing the types of premiums that are valued by consumers in a promotion. Most of the studies explore monetary promotions, while this study contributes to literature by exploring the gap about the effects of non-monetary sales promotions on purchase intention and brand selection, especially in the bank services environment. 相似文献

It is estimated that financial services comprise around 15% of the global economy. From the supply side, one key to meeting this demand is being able to educate and certify the people who provide these services. With the advent of the internet and related technologies, the ability to deliver financial services education synchronously to both online and on-campus attendees has become a viable alternative to pure face-to-face or pure online asynchronous education. Nonetheless, one question remains: can virtual technology deliver comparable quality of financial services educational experience as face-to-face teaching? It is this question our paper addresses using the theory of transactional distance. The theory of transactional distance postulates that for optimal learning, the cognitive gap between instructor(s) and learner(s) needs to be minimized. We explore how transactional distance in financial services education varies by attendance modality (in-class, online and mixed) in a synchronous, web-extended classroom. The implications for managers and researchers are explored. 相似文献

Pricing double barrier options under a volatility regime-switching model with psychological barriers
The prices of lots of assets have been proved in literature to exhibit special behaviors around psychological barriers, which is an important fact needed to be considered when pricing derivatives. In this paper, we discuss the valuation problem of double barrier options under a volatility regime-switching model where there exist psychological barriers in the prices of underlying assets. The volatility can shift between two regimes, that is to say, when the asset price rises up or falls down through the psychological barrier, the volatility takes two different values. Using the Laplace transform approach, we obtain the price of the double barrier knock-out call option as well as its delta. We also provide the eigenfunction expansion pricing formula and examine the effect of the psychological barrier on the option price and delta, finding that the gamma of the option is discontinuous at such barriers. 相似文献

In the probabilistic risk aversion approach, risks are presumed as random variables with known probability distributions. However, in some practical cases, for example, due to the absence of historical data, the inherent uncertain characteristic of risks or different subject judgements from the decision-makers, risks may be hard or not appropriate to be estimated with probability distributions. Therefore, the traditional probabilistic risk aversion theory is ineffective. Thus, in order to deal with these cases, we suggest measuring these kinds of risks as fuzzy variables, and accordingly to present an alternative risk aversion approach by employing credibility theory. In the present paper, first, the definition of credibilistic risk premium proposed by Georgescu and Kinnunen [Fuzzy Inf. Eng., 2013, 5, 399–416] is revised by taking the initial wealth into consideration, and then a general method to compute the credibilistic risk premium is provided. Secondly, regarding the risks represented with the commonly used LR fuzzy intervals, a simple calculation formula of the local credibilistic risk premium is put forward. Finally, in a global sense, several equivalent propositions for comparative risk aversion under the credibility measurement are provided. Illustrated examples are presented to show the applicability of the theoretical findings. 相似文献

This paper explores the dynamic consequences of variable investment-project size in a global economy consisting of many small open countries that are plagued with domestic credit market frictions. As is customary in the literature, borrowers provide some internal funds, but they also need external funds to implement their investment projects, which are subject to the costly-state-verification problem. Contrary to the literature, the investment-project size increases with the country’s own capital stock. We find that financial market globalization may lead to a process of oscillatory convergence, even in the absence of any exogenous shocks, if the investment-project size is very sensitive to the change in capital stock. 相似文献

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect. 相似文献

Bond laddering is a popular fixed-income investment strategy. The main purpose of this paper is to develop a methodology for determining private investors’ most interest rate risk (IRR)-return-efficient investment horizon for bond ladders (BLs), which are virtually free of credit risk. Two IRR measures of a continuously rolling and homogenous BL (CRHBL) are analytically derived under the assumption that interest rates are martingales. The first measure is the modified duration, which assumes a flat term structure of interest rates. However, this assumption is not fully supported by the empirical data and, thus, an additional IRR measure is proposed. Under each of these two measures, the ratios between the annual return in excess of the demand deposit rate and IRR of CRHBLs with different investment horizons are calculated. As expected, CRHBLs with rather low IRR are most risk-return-efficient. The results for the theoretical CRHBLs also apply to “real-world” discrete BLs. Thus, the proposed methodology can help private investors construct IRR-return-efficient discrete BLs. 相似文献

This paper analyzes the impact of performance, investment-firm-related, and macroeconomic variables on fundraising activities in private equity (PE). We use a novel, backward-looking approach to link current to preceding funds, which allows for including several parallel predecessor funds in our analysis. We employ logit and tobit models to a global sample of 1463 fundraising events observed between 2000 and 2010 in order to estimate the probability of raising and the volume of follow-on funds. Our results show that the average buyout duration of past transactions has a negative impact, whereas exits via an initial public offering (IPO) and deals without industry-style drift positively affect fundraising activities. Larger, industry-diversified, and independent PE firms exhibit a higher likelihood of fundraising and collect larger amounts. 相似文献

The 2000s in equity markets are marked by two major regulatory shocks: RegNMS in the United States, and MiFID in the European Union. Simultaneously, there is a massive increase in the proportion of high-frequency trading, and market orders volume. However, trading volumes do not significantly increase. We propose a theoretical model describing the effects of stock markets fragmentation on two types of investors optimization problems: “intermediary” high-frequency and “final” investors. Volatility has a permanent and a transitory component, whose weights depend on market fragmentation via the share of non-marketable orders of intermediary investors. The trading volume of final investors depends on market fragmentation both directly via transaction costs, and indirectly via total volatility. Finally a shock in fragmentation may lead to a decrease in trading volume, enhanced in the case of an equity markets crisis by a rise in the components of volatility. 相似文献
