A MCGP decision aid for homebuyers to make the best choice

This study adopts a new approach, the multi-choice goal programming (MCGP), to evaluate houses in order to help homebuyers to find better house based on the residential preferences. According to the function of MCGP, homebuyers can set multiple housing goals with multiple aspiration levels. This increases the flexibility to find a suitable house. Compared with other classical methods such as checklist and analytic hierarchy process, MCGP is more efficient, especially while considering a lot of housing criteria and house alternatives. In order to demonstrate the usefulness of MCGP decision aid for housing selection, a real case study is then provided. Furthermore, ten volunteers are invited to participate in the empirical experiment. The results also validate the effectiveness and efficiency of MCGP decision aid.     

The Asymmetric Information Problem in Taiwan's Cancer Insurance Market

This paper investigates the problem of asymmetric information in Taiwan’s cancer insurance market. Through the survey data, we find evidence of adverse selection existing in this market. Furthermore, we collect additional information on the individual, and find that the individual’s family cancer history contains additional valuable information. It can not only more accurately predict the probability of contracting cancer, as well as predict the willingness to purchase extended cancer insurance, but it can also help to mitigate the severity of adverse selection in the insurance market.     

Intergenerational appeal in advertising: impacts of brand–gender extension and brand history

An intergenerational (IG) appeal in an advertising campaign usually presents a nostalgic image with family portraits, emphasizing the traditions that have been passed on from generation to generation or harkening back to the ‘good old days’ between father and son, or mother and daughter. The IG appeal can effectively enhance a brand's image and induce that all-important consumer purchase. This paper takes gender differences (father/son or mother/daughter) into consideration while examining two moderators related to branding: (in)congruent brand–gender extension and brand history. Results indicate that a well-established brand history enhances the effects of the IG appeal. In addition, a congruent brand–gender extension increases the effects of the IG appeal. More interestingly, IG appeals can be effective in presenting a less established brand which has an incongruent brand–gender extension.     

Extending the link between entrepreneurial self-efficacy and intention: a moderated mediation model

This study extended the research on the relationship between entrepreneurial self-efficacy and intention by developing a moderated mediation model. This model posits that the link between entrepreneurial self-efficacy and intention is mediated by attitudes toward entrepreneurship and planned entrepreneurial control, and that these mediation processes are further moderated by subjective norms. Based on a sample of 308 valid responses, regression analysis yielded two noteworthy results. First, entrepreneurial self-efficacy positively affects intention through attitudes toward entrepreneurship and planned entrepreneurial control. Second, the direct effect of entrepreneurial self-efficacy on intention decreases as subjective norms increase. By contrast, the indirect intention effects of entrepreneurial self-efficacy through attitudes toward entrepreneurship and planned entrepreneurial control increase as subjective norms increase. In addition, the results indicated that subjective norms positively affect entrepreneurial intention. These findings indicated that the model advances the use of the theory of planned behavior and can be used to define a person as an entrepreneur.     

TRADE AND DIVERGENCE IN EDUCATION SYSTEMS

This article presents a theory on the endogenous choice of education policy and the two‐way causal relationship between trade and education systems. A country's education system determines its talent distribution and comparative advantage; the possibility of trade by raising the returns to the sector of comparative advantage in turn induces countries to further differentiate their education systems and reinforces the initial pattern of comparative advantage. Specifically, the Nash equilibrium choice of education systems by two countries interacting strategically are necessarily more divergent than their autarky choices, and yet less than what is socially optimal for the world.     

A STRUCTURAL RISK‐NEUTRAL MODEL FOR PRICING AND HEDGING POWER DERIVATIVES

We develop a structural risk‐neutral model for energy market modifying along several directions the approach introduced in Aïd et al. In particular, a scarcity function is introduced to allow important deviations of the spot price from the marginal fuel price, producing price spikes. We focus on pricing and hedging electricity derivatives. The hedging instruments are forward contracts on fuels and electricity. The presence of production capacities and electricity demand makes such a market incomplete. We follow a local risk minimization approach to price and hedge energy derivatives. Despite the richness of information included in the spot model, we obtain closed‐form formulae for futures prices and semiexplicit formulae for spread options and European options on electricity forward contracts. An analysis of the electricity price risk premium is provided showing the contribution of demand and capacity to the futures prices. We show that when far from delivery, electricity futures behave like a basket of futures on fuels.     

Unconventional Monetary Policy in the Eurozone: A Lack of Forward Guidance?

From July to December 2011, the three-month EURIBOR-OIS and EURIBOR-Repo spreads quadrupled and reached 100 basis points due to a stabilization of the EURIBOR and a decrease in the overnight index swap (OIS) and Repo. Using a specific monetary policy announcements and financial indicators database, we find that the European Central Bank’s (ECB’s) unconventional measures did not systematically have a calming effect: Asset buyout announcements decreased market strains, whereas interest rates and liquidity provision announcements did not. Moreover, liquidity provision seems to have a stressing effect. Our findings are consistent with the theoretical underpinnings according to which forward guidance crucially determines the effectiveness of unconventional monetary policies.     

Measuring service experience: a utility-based heuristic model

This research aims to construct a model to evaluate service experience. We develop a novel model for service experience by incorporating positive and negative dimensions. We demonstrate that greater utility from experience results in greater value of service experience. We also discovered negative dimensions are the key reason; especially waiting time. We separated five groups to help firms explore deeper insights from various dimensions. The value of service experience in group of middle range has the greater contrast between positive and negative dimensions than the other groups. Service providers can obtain customer perception to adjust or revise the service components.     

Does prior record matter in the wealth effect of open-market share repurchase announcements?

This study investigates whether prior experience of share repurchases matters in the market reactions to the subsequent repurchase announcements. Specifically, we study the prior record on actual buybacks and post-announcement stock performance. We find that upon the announcement of share repurchases, stock markets not only respond more positively to those made by firms that have better record on actual buyback following their previous repurchase plan announcements, but also experience a stronger reaction for announcing firms with better stock performance after prior repurchase announcements. These results hold even after controlling for other variables that are found important in influencing the market reactions to repurchase announcements.
