Risk attitudes, randomization to treatment, and self-selection into experiments

Randomization to treatment is fundamental to statistical control in the design of experiments. However randomization implies some uncertainty about treatment condition, and individuals differ in their preferences towards taking on risk. Since human subjects often volunteer for experiments or are allowed to drop out of the experiment at any time if they want to, it is possible that the sample observed in an experiment might be biased because of the risk of randomization. On the other hand, the widespread use of a guaranteed show-up fee that is non-stochastic may generate sample selection biases of the opposite direction, encouraging more risk averse samples into experiments. We directly test these hypotheses that risk attitudes play a role in sample selection. Our results suggest that randomization bias does affect the overall level of risk aversion in the sample we observe, but that it does not affect the demographic mix of risk attitudes in the sample. We show that the common use of non-stochastic show-up fees can generate samples that are more risk averse than would otherwise have been observed.     

Measuring the impact of R&;D on Productivity from a Econometric Time Series Perspective

In this paper we argue that the standard sequential reduction approach to modelling dynamic relationships may be sub-optimal when long lag lengths are required and especially when the intermediate lags may be less important. A flexible model search approach is adopted using the insights of Bayesian Model probabilities, and new information criteria based on forecasting performance. This approach is facilitated by exploiting Genetic Algorithms. Using data on U.K. and U.S. agriculture the bivariate time series relationship between R&D expenditure and productivity is analysed. Long lags are found in the relationship between R&D expenditures and productivity in the U.K. and in the U.S. which remain undiscovered when using the orthodox approach. This finding is of particular importance in the debate on the optimal level of public R&D funding.JEL Classification: C22, C51, Q16     

The use of on-line summative assessment in an undergraduate financial accounting course

According to the Quality Assurance Agency [QAA (2006). Section 6: Assessment of students, Code of practice for the assurance of academic quality and standards in higher education. <http://www.qaa.ac.uk/>. Accessed 14.03.2007] “Assessment describes any processes that appraise an individual’s knowledge, understanding, abilities or skills” and is inextricably linked to a course or programme’s intended learning outcomes. Assessment also has a fundamental effect on students’ learning where it serves a variety of purposes including evaluation, feedback and motivation. Assessment also provides a performance indicator for both students and staff. Computer-aided assessment (CAA) offers an option for “sustainable assessment” and provides opportunities for creating innovative assessment practices that help engage students and increase their motivation for learning. This paper reports the findings of a qualitative study where a series of on-line summative assessments were introduced into a first-year financial accounting course. Feedback from students obtained from an evaluative survey and focus group interviews indicates that assessment played a significant role in the teaching/learning process. That is, students perceived a beneficial impact on learning, motivation, and engagement.     

Examination of the adoption of augmented reality: a VAM approach

ABSTRACT

Despite the growing importance and popularity of augmented reality (AR) technologies in hospitality and tourism, little research to identify the degree of user adoption, particularly in the business travel sector, has been conducted. Based on a questionnaire administered to 161 stakeholders attending two international conferences in Hong Kong, user experiences and adoption intention were examined and analyzed through structural equation modeling. Adoption was explored using a value-based adoption model. AR adoption is affected by its perceived value to which the benefits of usefulness and enjoyment contribute, along with newly identified components of technicality and captivating inputs.     

Is the expected utility maximization hypothesis refutable by finite market data: The case of two observations

It is shown that with only two observations on the asset demand functions of an investor, it is not possible to refute the hypothesis of expected utility maximization on the part of the investor as long as the axioms of revealed preference are satisfied.     

Teaching student philanthropy—Possibilities for practice within the UK higher education sector

This practice paper reflects on lessons learnt from an undergraduate philanthropy module introduced across different programmes within the division for the Study of Law, Society, and Social Justice  at the University of Kent, United Kingdom. The module applies service-learning and experiential learning pedagogy to ensure students critically engage with community and societal issues; recognise themselves as philanthropists; and engage in a responsible decision-making process with their cohort. As one of the first UK Higher Education student philanthropy modules, lessons learnt provide important general reflections for student philanthropy modules internationally, alongside offering a potential ‘blueprint’ within the UK context. Aligning with others (such as McDougle's study) and drawing on critical reflections from students and partners, suggests that experiential learning pedagogy is most successful when carried out in a diverse and multidisciplinary learning space where students reflect on their own moral position alongside others to build consensus.     

Pension Funds and Emerging Markets

This paper focuses on the investment behavior of pension funds in developed and emerging market countries. First, it analyzes the main determinants of the emerging market asset allocation of pension funds in developed countries. Second, it assesses how pension funds in emerging markets have contributed to the development of local securities markets. Third, it analyzes the determinants of pension funds' investment performance. The paper concludes with a discussion of why the emerging market asset allocation of pension funds in developed countries is likely to increase and what the challenges faced by pension funds in emerging markets are.     

Selection attributes of wedding banquet venues: An exploratory study of Hong Kong prospective wedding couples

Despite the significant contribution of the wedding business to the hospitality industry, few studies of wedding banquet venues have been conducted. This study aimed to investigate the perception of Hong Kong prospective wedding couples of the importance of venue selection attributes. Among the 25 venue attributes identified, employee attitude was viewed by the 205 respondents as the most important, followed by cleanliness and food quality. Among the 11 extrinsic and intrinsic personal attributes, first impression was the most influential while an auspicious wedding date was the least. Marketing strategies are recommended to industry practitioners on the basis of the findings.
