Online referral systems help firms attract new customers and expand their customer base by leveraging the social relationships of existing customers. We integrate ultimatum game theory, which focuses on fairness, with motivation theories to investigate the effects of social distance and monetary incentives on the performance of three competing designs for online referral systems: rewarding only...

One of the reasons why market economies are able to thrive is that they exploit the willingness of entrepreneurs to take risks that laborers might prefer to avoid. Markets work because they remunerate good judgement and punish mistakes. Indeed, modern contract theory is based on the assumption that principals are less risk averse than agents. We investigate if the risk preferences of entreprene...

Currently, the bulk of the new empirical work on estimating the impact on learning of various education projects/ programmes/policies, while based on sound principles of estimating causal impacts, is far too inadequately theorised and specified to be of much immediate and direct use in formulating effective action to accelerate learning. Therefore, just “more of the same” empirical research is ...

Empirical studies are often carried out with students because they are viewed as inexpensive subjects for pilot studies. Though the literature has mostly focused on their external validity, we believe that there are a number of other issues that need to be investigated in empirical studies with students. In our past research, we have identified four viewpoints, each of which needs to be taken i...

The management of knowledge is a multifaceted organizational process that involves three parts. They are (i) a strategy, (ii) the creation of an organizational environment or space for knowledge known as the “enabling context” or “Ba” and (iii) an operational/action toolbox consisting of IT tools and managerial practices to effectively put the strategy into action. The main objective of this pa...

Recently, conventional housing of laboratory rodents has been criticised for inducing abnormal behaviours and poor well-being, which also questions the validity of many animal experiments. Environmental enrichment may prevent abnormal behaviours and improve animal wellbeing, but concerns have been raised that it might also disrupt standardisation, thereby reducing the precision and replicabilit...

We present the results of a study that focuses in on issues of validity of the motivation towards the environment scale (MTES) in the context of Flanders (the Flemish-speaking community in Belgium). The instrument was developed almost two decades ago in Canada, and is designed to measure the self-determined motivation of people for performing pro-environmental behaviors, but has not yet been ap...

In this paper we assess the reading preference for marketing journals by deriving a journal utility scale based on click responses to table of contents postings to the ELMAR virtual community. Use of ELMAR data provides a unique window into journal importance, allowing us to look at table of contents reading behavior rather than citing behavior or attitudinal constructs as has been the case in ...
