This paper proposes an extension of the minimal Hellinger martingale measure (MHM hereafter) concept to any order q≠1 and to the general semimartingale framework. This extension allows us to provide a unified formulation for many optimal martingale measures, including the minimal martingale measure of Föllmer and Schweizer (here q=2). Under some mild conditions of integrability and the absence of arbitrage, we show the existence of the MHM measure of order q and describe it explicitly in terms of pointwise equations in ?d. Applications to the maximization of expected power utility at stopping times are given. We prove that, for an agent to be indifferent with respect to the liquidation time of her assets (which is the market’s exit time, supposed to be a stopping time, not any general random time), she is forced to consider a habit formation utility function instead of the original utility, or equivalently she is forced to consider a time-separable preference with a stochastic discount factor. 相似文献
A retail franchisor needs growth capital so that the brand continues to grow and franchisor–franchisee relations remain strong. However, access to corporate liquidity to fund such franchise growth options is not unlimited. A method of raising finance particularly suited to retail franchisors is intellectual property (IP) securitization that allows companies to account for intangible assets such as intellectual property, royalty and brands and realize their full value. In recent years, a number of large restaurant franchisors have securitized their brands to raise funds, including Dunkin Brands and Domino's Pizza (Domino's). We use property rights approach to show that IP securitization provides mechanisms that explicitly define ownership of intangible assets within the securitization structure and thus enables a company to raise funds against these assets. Using a case study example of a retail franchise IP securitization transaction, we also provide evidence that these mechanisms are not overly restrictive and can be used more widely to help fund retail franchise growth and expansion. 相似文献
This paper assesses the impact of the ‘decoupling’ reform of the Common Agricultural Policy on the labour allocation decisions of Irish farmers. The agricultural household decision‐making model provides the conceptual and theoretical framework to examine the interaction between government subsidies and farmers’ time allocation decisions. The relationship postulated is that ‘decoupling’ of agricultural support from production would probably result in a decline in the return to farm labour but it would also lead to an increase in household wealth. The effect of these factors on how farmers allocate their time is tested empirically using labour participation and labour supply models. The models developed are sufficiently general for application elsewhere. The main findings for the Irish situation are that the decoupling of direct payments is likely to increase the probability of farmers participating in the off‐farm employment market and that the amount of time allocated to off‐farm work will increase. 相似文献
To be competitive and successful in congress tourism, destinations must learn which congress tourism-related attributes are important and how they perform against their main competitors. This study identifies the importance and performance of destination attributes in Antalya, Turkey, and compares the position of these attributes to those of its main rival in congress tourism, ?stanbul. Importance performance competitor analysis results show that, according to domestic participants, Antalya has to focus on “sight-seeing and cultural attractions” and “outside entertainment.” For international participants, “climate,” “choice of meeting and housing properties,” and “suitability of conference facilities” exhibit higher performance in Antalya than ?stanbul. 相似文献
There is much controversy about the role that trade liberalization, technological change and relative factor supplies have played in bringing about changes in the relative wage of the unskilled workers. Much of the empirical work on this issue has focused on the industrial countries and paid little attention to developing countries. To fill this gap, this study develops a special data set to examine the relative wage behaviour of a large number of developing countries. An empirical model based on the theory is used to test different explanations of the relative wage change. As predicted by the technology explanation, the empirical analysis in the study finds a significant negative link between the relative wage of unskilled workers and the technology index. The analysis, however, does not find a significant role for labour supplies or trade liberalization in determining the relative wage of unskilled–skilled workers. 相似文献
The twenty-first century has seen an increase in ethical misconduct at the workplace, highlighting the need to stimulate discussion on the role of work ethics. The objective of the current study is to extend the literature on work ethics by examining the role of Islamic work ethic in enhancing the task performance of employees. The current study proposes that psychological capital mediates the relationship between Islamic work ethic and task performance. It is also proposed that ethical leadership might act as a boundary condition that boosts the positive relationship between Islamic work ethic and psychological capital. Data were collected in three-time lags from employees working in the service sector of Pakistan (N?=?218) through the questionnaire. The results supported the mediation and moderation hypothesis, confirming that psychological capital mediates the relationship between Islamic work ethic and task performance. Ethical leadership moderates the relationship between Islamic work ethic and psychological capital. The results offer implications for theory and practice. Limitations and future research directions are also discussed.
The study examines and highlights the impact of selected foreign inflows (aid, trade, FDI, debt and remittances) on the economic growth of the South Asian Association for Regional Cooperation (SAARC) countries. The existent literature lacks a comprehensive analysis of the SAARC countries as countries like Afghanistan, Bhutan and the Maldives have largely been ignored due to the shorter time periods of available data. The study is empirical in nature and utilizes panel data techniques on macroeconomic data for the period 2008–2015. Foreign aid and foreign direct investment are found to impact economic growth positively. Foreign debt and trade flows are found to adversely affect economic growth. No relationship is established between the flow of remittances and the economic growth of these countries. The obtained results are robust to different proxy variables and the addition of macroeconomic variables. For the first time, the study provides policy implications based on the data of all SAARC countries. The study recommends focusing on increasing the inflows of resources in the form of aid and foreign direct investment (FDI) from the developed world to achieve higher economic growth. 相似文献
Visitors are impressed by specific destination attributes, which are sometimes the main motivating reasons for the travel selection or sometimes they are just one of the elements of a whole destination experience. This is because tourism and travel products are generally a combination of several different supplier offerings or they are a combination of the natural and artificial attributes of a destination that cannot be fully known before the experience of travel. Moreover, the importance and influence of these attributes on overall visitor satisfaction may differ considerably, depending on the market segments. In recent years, some studies have shown that the influences of destination attributes on overall visitor satisfaction are not symmetric in every case. For the purposes of this study, the symmetric and asymmetric influences of destination attributes are investigated for three major market segments of the Side-Manavgat area, Antalya, Turkey. The results show that the importance and influences of destination attributes may change according to the analysis technique employed and the market segment examined. 相似文献
