We price an American floating strike lookback option under the Black–Scholes model with a hypothetic static hedging portfolio (HSHP) composed of nontradable European options. Our approach is more efficient than the tree methods because recalculating the option prices is much quicker. Applying put–call duality to an HSHP yields a tradable semistatic hedging portfolio (SSHP). Numerical results indicate that an SSHP has better hedging performance than a delta-hedged portfolio. Finally, we investigate the model risk for SSHP under a stochastic volatility assumption and find that the model risk is related to the correlation between asset price and volatility.  相似文献

This study examined the influence of psychobiological motivational traits related to individual approach and avoidance tendencies on cognitive processing of in‐game advertising. Participants played a custom‐built video game containing billboard advertisements. After playing the game, participants’ approach, positivity offset (PO), and avoidance, negativity bias (NB), traits were measured using the motivation activation measure (MAM). Recognition and recall memory were greater for high PO and low NB trait individuals. The findings of this study imply that advertising in first‐person‐shooter (FPS) video games may be most effective when targeting individuals with simultaneously high PO and low NB, risk takers, but least effective for those with low PO and high NB, risk avoiders.  相似文献

Based on the componential theory of creativity, this research built and tested a new theoretical model that links the 4P model (people, product, place, and process) with creativity via several intervening variables. Survey data and two-step structural equation modeling were used to evaluate a sample of 338 employees surveyed from 57 tourism and hospitality organizations in Taiwan. As anticipated, we found that people (e.g. personality) positively affected place (e.g. organizational environment and participation) and creative process (e.g. data collection, idea generation, and confirmation), which in turn influenced product outputs of creativity and satisfaction.  相似文献

This study examines whether people with disabilities(PWD) participate in leisure and travel activities with their desired companions and if there are discrepancies between their social networks and real recreation companions. The recreation companionship and travel behaviour of PWD have not been thoroughly explored, particularly in non-Western contexts. Accordingly, data were collected from 494 respondents in South Korea, and findings suggest that there was a significant gap between companions PWD desire and those they actually maintain. Travel and tourism were the least frequent recreation activities for PWD. The results can provide managerial implications regarding practices of inclusive and accessible tourism.  相似文献

Imposing user fees in Nature-Based Tourism (NBT) contexts has been a controversial issue. Based on the notions of justice and fairness, this study extended previous work examining the relationship between attitudes toward user fees and spending support. In a proposed structural model of price fairness, fee spending support, and willingness to pay (WTP), this paper identified the antecedents of WTP user fees, and empirically examined to what extent the data fit the model. Furthermore, the moderating role of place attachment in the model was investigated by using multiple-group structural equation modeling. Subjects (n = 562) were recreational tourists to a forest area in the southeast U.S. Results revealed that spending support partially played a mediating role in the relationship between perceived price fairness and WTP user fees. A multiple-group invariance test also demonstrated that while the degree of place identity moderated the effect of price fairness on spending support, the degree of place dependence did not influence the relationships among the antecedents of WTP.  相似文献

The money supply impacts on interest rate and liquidity were first proposed in 1961 by Friedman, the late Nobel laureate. The liquidity effect has yet received unanimous empirical support. Also, research interest on liquidity subsided in the 2000s. Using quarterly data over 1960–2011 and simultaneous solution to a system of equations, this paper reports positive liquidity effect from money supply. By extending the system of equations with a liquidity equation and after controlling the effect of earnings, evidence is found of a significant positive effect from liquidity on share prices. Money supply is found to be endogenous as in post Keynesian theory. These findings, obtained after solutions to several econometric deficiencies in prior studies, provide clear verification of the endogenous money supply theory, money effect on liquidity and on the extension of the model for a liquidity effect on asset prices.  相似文献

We investigate the determinants of foreign borrowing costs in a stochastically growing economy. We find that these increase with the debt-wealth ratio, depending also upon the volatilities of domestic and foreign origin, and the length of debt contract. In addition, the sensitivity of the short-term debt supply to the debt-wealth ratio exceeds that of long-term debt, and the effects of volatility on the borrowing premium, growth of wealth, and its volatility, depend on the relative size of a direct effect and a secondary portfolio-adjustment effect of the initial shock, as well as the length of the debt contract. Panel regressions suggest that the empirical evidence generally support the theoretical predictions.  相似文献

Predicting issuer credit ratings using a semiparametric method   总被引:1,自引:0,他引:1  
This paper proposes a prediction method based on an ordered semiparametric probit model for credit risk forecast. The proposed prediction model is constructed by replacing the linear regression function in the usual ordered probit model with a semiparametric function, thus it allows for more flexible choice of regression function. The unknown parameters in the proposed prediction model are estimated by maximizing a local (weighted) log-likelihood function, and the resulting estimators are analyzed through their asymptotic biases and variances. A real data example for predicting issuer credit ratings is used to illustrate the proposed prediction method. The empirical result confirms that the new model compares favorably with the usual ordered probit model.  相似文献
