Profitability of momentum strategies in international markets: The role of business cycle variables and behavioural biases

The paper investigates whether business cycle variables and behavioural biases can explain the profitability of momentum trading in three major European markets. Unlike previous studies, the paper nests both risk-based and behavioural-based variables in a two-stage model specification in an attempt to explain momentum profits. The findings show that, although momentum profitability in European markets is unexplained by conditional asset pricing models, it is attributable to asset mispricing that systematically varies with global business conditions. In addition, behavioural variables do not appear to matter much. Thus risk factors, which are undetected thus far and are largely attributable to the business cycle, could explain the momentum payoffs in European stock markets.     

Self‐regulation through Goal Setting*

Goals are an important motivator. But little is known about why and how people set them. We address this issue in a model based on two stylized facts. First, goals serve as reference points for performance. Second, present‐biased preferences create self‐control problems. We show the power and limits of self‐regulation through goals. Goals increase an individual's motivation—but only up to a certain point. Furthermore, they are painful self‐disciplining devices. Thus, greater self‐control problems may result in tougher goals; but for a severe present bias goals either lack a motivating force, or are too painful to be accepted.     

Service quality and its effect on customer satisfaction and customer behavioral intentions: hotel and ryokan guests in Japan

This study analyzes the effect of service quality on customer satisfaction and customer behavioral intentions at hotels and ryokan (traditional Japanese inns). In this empirical research, questionnaires were sent to guests at seven sites: three hotels and four ryokan. Service quality, as perceived by guests, affected customer satisfaction and customer behavioral intention. Results from this empirical study show strong evidence of service quality as perceived by guests being influenced by the type of accommodation. Also, among service quality factors, “physical aspect” had the most powerful impact on customer satisfaction and customer behavioral intention. “Creativeness” ranked second, followed by “unexpected service” and “encounter performance”. The prominence of physical aspects probably reflects the distinctiveness of the service of offering a one-night stay. However, as a certain level of physical facilities is taken for granted at lodging facilities above a certain price, “creativeness”, the second most powerful factor, becomes decisively important.     

Integration Deficits of IT Controlling

The paper is based on the thesis that IT controlling suffers from two integration deficits with regard to its methods base: On the one hand, this is a lack of synchronization between research on IT controlling methods and developments in practice; on the other hand, a lack of integration of IT controlling methods with methods of business and information systems engineering (BISE). Based on this assumption, the paper investigates historical developments in IT controlling research and practice to derive theses about the present state of method integration. The analysis finds indications for further potential for method integration and identifies these potentials. Requirements towards method integration are derived from an analysis of the identified integration potentials and two examples illustrate how to realize further integration. Accepted after two revisions by the editors of the special focus.
