Cultural differences in organizational citizenship behavior: a comparison between Chinese and American employees

The present study examined the differences in the perceptions of organizational citizenship behavior (OCB) between Chinese and American employees. Survey responses concerning the presence of OCB in their organizations were collected from a total of 393 employees. Analyses showed that Chinese and American employees reported similar levels of personal support and conscientious initiative in their organizations, but Chinese employees reported higher levels of organizational support in comparison with American employees. In addition, results indicated that perceptions of personal support, organizational support, and conscientious initiative were a function of job/hierarchical level such that management reported lower levels on all three dimensions of OCB. Finally, the results showed that country and job/hierarchical level do not interact to influence perceptions of organizational citizenship behavior. Implications and directions for future research on cultural differences in organizational citizenship behavior are discussed.     

Asynchronized multiperiod commitments and cycles

We consider a game where agents can synchronize or stagger their decisions. We compare the outcomes of both timing patterns, and show that spillovers and strategic interactions are crucial for such a comparison. A typology used in industrial organization, distinguishing four cases (‘Fat-Cat’, ‘Top Dog’, Lean and Hungry’, ‘Puppy Dog’), allows us to compare the actions taken in the staggered variant and in the synchronized one. The staggered variant exhibits cycles and players are both better-off when there are strategic complementarities between them. A timing game is then set-up so as to endogenize the choice between the two variants we study.Two examples are developed: (i) Bertrand competition and (ii) a wage setting game when there are two monopoly unions in two interrelated firms. We show that the staggering of price decisions generates counter-cyclical mark-ups in the first example, and the staggering of wage decisions generates cycling output in the industry in the second example.     

A remark on rational expectation equilibria with incomplete markets and real assets

In this note, I established the existence, for a generic set of endowments, of a fully revealing rational expectation equilibrium (REE) in an economy characterized by incomplete markets and real assets.     

Investing in the S&P 500 index: Can anything beat the buy‐and‐hold strategy?

Determining whether investment strategies exist that provide higher (risk‐adjusted) returns than buying and holding the S&P 500 stock market index is not only highly relevant for finance theory, but also for the asset management industry. This study conducts a comprehensive test using realistic investment strategies based on monthly seasonalities, technical indicators, and fundamental factors (over 4,100 strategies in total). To assess statistical significance, we use Hansen's data‐snooping‐resistant SPA test. The results show that only investment strategies trying to exploit underreaction and overreaction effects with technical indicators dominate the buy‐and‐hold strategy in some simulation setups. These investment strategies are clearly superior to the strategies based on seasonalities and fundamental factors. Given that underreaction and overreaction effects are mainly justified with cognitive biases, our results support the economic relevance of behavioral finance insights.     

Creativity methods in technological forecasting

“Technological Forecasting and Applications” was the title given to the Second European Technological Forecasting Association conference held in Paris in May. It was sponsored by ADETEM, The Association for the Development of Marketing Techniques, and was therefore somewhat inclined to that aspect of management studies. However, a number of papers reflected the increasing acceptance of the notion of technological forecasting both in France and in the UK, and illustrated various methods and applications. An example is the following contribution which introduces creativity techniques to the practice of technological forecasting.
