Summary The relationship between home ownership of Dutch elderly households and age is strongly negative. Other studies suggest that this age gradient should be attributed to a cohort effect. In this paper, we investigate where those cohort effects come from. We also observe that mortgage ownership among elderly home owners increased considerably during the nineties. Using panel data, we estimate models explaining home and mortgage ownership by age, cohort, and time effects, as well as other factors. Cohort and time effects are modelled explicitly using macro economic and housing market related variables. We find that the level of GDP per capita when the household head was young is the main factor explaining generation effects in home ownership among the elderly. After accounting for cohort effects it also appears that home ownership decreases slightly with age. Mortgage ownership among elderly home owners rose considerably during the nineties due to house price increases and due to financial innovation in the mortgage market. Cohort effects are also important. A supplementary analysis suggests that those cohort effects are due to the fact that the accidental bequest motive is becoming less important.

Child Labor and Multinational Conduct: A Comparison of International Business andStakeholder Codes

Increasing attention to the issue of child labor has been reflected in codes of conduct that emerged in the past decade in particular. This paper examines the way in which multinationals, business associations, governmental and non-governmental organizations deal with child labor in their codes. With a standardized framework, it analyzes 55 codes drawn up by these different actors to influence firms external, societal behavior. The exploratory study helps to identify the main issues related to child labor and the use of voluntary instruments such as codes of conduct. Apart from a specific indication of the topics covered by the code, especially minimum-age requirements, this also includes monitoring systems and monitoring parties. Most important to company codes are the sanctions imposed on business partners in case of non-compliance. Severe measures may be counterproductive as they do not change the underlying causes of child labor and can worsen the situation of the child workers by driving them to more hazardous work in the informal sector. This underlines the importance of a broad rather than a restrictive approach to child labor in codes of conduct. The paper discusses the implications of this study, offering suggestions for future research.     

Hospitality and Tourism Online Reviews: Recent Trends and Future Directions

In view of the increasing popularity of online reviews and their significant impact on individual buying behavior as well as on the supply side, this study reviewed and analyzed articles related to online reviews in tourism and hospitality published in academic journals between 2004 and 2013. Based on a keyword-driven search and a content analysis, 50 articles were identified as relevant and classified into five topics. The findings revealed that (a) more than half of the analyzed articles focus on hotels and apply empirical methods based on secondary data, (b) more attention has been paid to the relationship between online reviews and online buying as well as satisfaction and online management, and (c) opinion mining of online reviews, motivation to post reviews, and the role of reviews are evenly distributed. This paper also discussed significant topical and methodological trends, contributes to an overall understanding of existing research and its limitation.     

Research Note: Addressing Tourism Public Policy Issues through Attitude Segmentation of Host Communities

Resident attitudes are important in identifying the impact of tourism within communities and in determining local policy, planning and management responses for the development of tourism. Additionally, tourism policies established are vital for the marketing of cities, regions and countries. This paper examines tourism public policy, with particular reference to the importance of addressing host community interests and involving host communities in public policy decision making. It outlines a segmentation study undertaken on New Zealand residents' views on tourism and how these segments can be applied to tourism policy making.     

Measurement Error in Education and Growth Regressions*

The use of the perpetual inventory method for the construction of education data per country leads to systematic measurement error. This paper analyzes its effect on growth regressions. We suggest a methodology for correcting this error. The standard attenuation bias suggests that using these corrected data would lead to a higher coefficient. Our regressions reveal the opposite. We discuss why this is the case.     

Catching a draft: on the process of selecting quarterbacks in the National Football League amateur draft

The reverse order college draft gives the worst teams in the National Football League (NFL) the opportunity to hire the best amateur talent. For it to work effectively, teams must be able to identify the “best” talent. Our study of NFL quarterbacks highlights problems with the draft process. We find only a weak correlation between teams’ evaluations on draft day and subsequent quarterback performance in the NFL. Moreover, many of the factors that enhance a quarterback’s draft position are unrelated to future NFL performance. Our analysis highlights the difficulties in evaluating workers in the uncertain environment of professional sports.     

Option trading and individual investor performance

This paper examines the impact of option trading on individual investor performance. The results show that most investors incur substantial losses on their option investments, which are much larger than the losses from equity trading. We attribute the detrimental impact of option trading on investor performance to poor market timing that results from overreaction to past stock market returns. High trading costs further contribute to the poor returns on option investments. Gambling and entertainment appear to be the most important motivations for trading options while hedging motives only play a minor role. We also provide strong evidence of performance persistence among option traders.     

INTERNATIONAL CLIMATE AGREEMENTS UNDER INDUCED TECHNOLOGICAL CHANGE

We examine the impact of technological change on the stability of climate coalitions and explore how international cooperation on abatement affects the incentives of signatories to invest in R&D to reduce emissions. We compare the case of no technological change with exogenous technological change and induced technological change. In the latter case R&D investments are endogenous. We find that the highest equilibrium pay‐offs are achieved in the case of induced technological change. Furthermore, the formation of a climate coalition boosts R&D investments in carbon abatement technologies in signatory countries.
