Brighter prospects? Assessing the franchise advantage using census data

This paper uses Census microdata to examine how starting a business as a franchise rather than an independent business affects its survival and growth prospects. We assess factors that influence the decision to become a franchisee and use various empirical approaches to correct for selection bias in our performance analyses. We find that franchised businesses on average exhibit higher survival rates than independent businesses; but importantly, the difference is small compared with claims in the trade press. The effect is also short lived: conditional on surviving a year or two, we no longer find survival (or growth) differences. We then explore two potential sources for this small survival advantage, namely franchisors’ screening process and the benefits arising from the brand and business know‐how provided by franchisors. We find evidence that both of the sources contribute to the franchising advantage.     

What do professional forecasters actually predict?

This paper studies what professional forecasters predict. We use spectral analysis and state space modeling to decompose economic time series into trend, business cycle, and irregular components. We examine which components are captured by professional forecasters by regressing their forecasts on the estimated components extracted from both the spectral analysis and the state space model. For both decomposition methods, we find that, in the short run, the Survey of Professional Forecasters can predict almost all of the variation in the time series due to the trend and the business cycle, but that the forecasts contain little or no significant information about the variation in the irregular component.     

Analysing reviews in the Web 2.0: Small and medium hotels in Portugal

This study presents a characterisation of online reviews for small and medium hotels (SMH) in Portugal. We collected and analysed 1500 online reviews from 50 SMH. The findings show that room, staff and location were the concepts most frequently appeared in the reviews, with cleanliness, friendliness, helpfulness, and centrality of position the terms most frequently used to qualify the concepts. This study points out the main features which SMH managers should prioritize.     

Personalisation–privacy paradox: The effects of personalisation and privacy assurance on customer responses to travel Web sites

Personalisation refers to individualizing products, services, and contents according to customer interests and preferences. In order to deliver appropriate personalised offerings, firms inevitably need to collect rich customer data profiles. Prior research suggests that personalised services lead to positive customer responses such as increased willingness to disclose personal information and make purchases. However, another stream of research emphasizes negative outcomes of personalisation – namely, privacy concerns surrounding the use of personal information and associated negative effects on behaviour. The objectives of this study are twofold: (1) to examine how privacy assurance affects proximal outcomes of personalisation, such as perceived usefulness and privacy concerns; and (2) to identify the role such outcomes play in predicting customer behavioural responses, such as willingness to disclose personal information and make purchases. Our findings show that enhancing privacy assurance increases the perceived usefulness of services and decreases customer privacy concerns. Moreover, customer behavioural responses are positively related to the perceived usefulness of services and negatively associated with privacy concerns. However, despite the positive effects on perceived usefulness and purchase intentions, personalisation has no effect on privacy concerns and intentions to disclose personal information.

Consumer morality in times of economic hardship: evidence from the European Social Survey

Crimes of everyday life, often referred to as unfair or unethical practices committed in the marketplace by those who see themselves and are seen as respectable citizens, have burgeoned as a result of the transformations in the European economy in the late 20th century, namely the transition to neo‐liberal markets and the emergence of consumer society. A ‘cornucopia of new criminal opportunities’ has given rise to a new range of crimes such as ripping software, making false insurance claims or paying cash on hand to circumvent taxes. These shady behaviours (legal or not) are part of people's experience, albeit they are collectively regarded as morally dubious. Taken collectively, crimes of everyday life are indicators of the moral stage of a particular society and therefore a valuable instrument for social and political analysis. This paper addresses the question of whether and under which conditions feelings of economic hardship trigger crimes of everyday life. A multilevel theoretical and empirical perspective that integrates theories stemming from political science, sociology, and social psychology is adopted. I start by exploring the embeddedness of economic morality in social institutions, followed by an elaboration of the concept of market anomie to account for deviant behaviour in the marketplace, to finally step down to the examination of the correspondence between social attitudes and consumer behaviour, as postulated by the Theory of Planned Behaviour. The empirical study relies on micro data from the European Social Survey (ESS) (Round 2) and attempts to model, for each country, a formative measure of crimes of everyday life based on socio‐demographic variables and the current economic situation, as it is perceived by the individual (taken as a measure of relative deprivation). The resultant country‐specific regression coefficients are mapped onto the broader economic and normative context of 23 European countries. The results reveal that crimes of everyday life are driven by feelings of economic hardship only in countries where normative factors dictate their deviance. In countries where fraudulent behaviour is more generalized, inner motivations to offend play a secondary role as the more privileged consumers are more likely to commit fraud as they interact more often with the market. In turn, normative aspects result from a dynamic interplay of cultural and economic factors. As the economy grows faster, the tendency to offend in the market becomes more visible, but only in countries whose gross domestic product (GDP) stands above the European average. In countries with low GDP, the normative landscape is shaped by cultural factors that seem to obfuscate the power of economic factors favourable to consumer fraud.
