The Substitution Effect of Mobile Games on Console Games: An Empirical Analysis of the Japanese Video Game Industry

In this paper, we discuss the substitution effects between mobile games and console games. We estimate such effects by a fixed-effect regression with instrumental variables using panel data of about 100,000 observations. The results showed that the substitution effects of playing smart devices on 3DS, Wii, and PSP were recognizable, but did not have significant effects on PS3, and the substitution effects on PSP were very small. Therefore, mobile games had a substitution effect on casual console games, or on console games in which the play situation resembled mobile games. In addition, the substitution effects were at most about 0.1. The substitution effects were small. Our results indicate that mobile games represent the pioneers in the new market of gaming at least during our observation period. But new games and traditional games will coexist for a while.     

Emotional stability: A new construct and its implications for individual behavior in organizations

Despite being generally well studied, emotional stability (ES) has not yet been widely accepted as a satisfactory and solidly valid theoretical construct. Without a clearly defined and validated construct, it is difficult to infer what ES means for the behavior and decisions of individuals as well as the performance of groups and organizations. Based on self-organization theory, this study infers a two dimensional construct for ES (threshold and recovery) under the framework of dynamic change and complexity. Two studies were conducted in China to develop and examine the construct of ES in an organizational context. The psychometric examination indicated that the newly developed construct of ES has discriminant and convergent validity with respect to different though related constructs such as the Big Five personality model and emotional intelligence (EI). It also demonstrates incremental validity in predicting group leadership, job satisfaction, job self-efficacy, and commitment. The findings also demonstrate that ES moderates the relationship between individual commitment and group relationship conflict. The results indicate that self-ratings effectively reflect the theoretical construct, whereas peer ratings and supervisor ratings create different biases. Additional theory, empirical, and methodological contributions are also discussed.     

A pilot study of venture capital investment appraisal in Australia

Illiquidity, volatile returns and lack of information are sources of the high risk that characterise the investments made by venture capitalists (VCs). Despite the importance of such investments in the contemporary business and technological environment, and the associated risk-related difficulties, little Australian research has been conducted into the decision-making processes of VCs. This study investigates both the investment process and some of the strategies used by VCs for reducing selected risks. The specific source of risk examined is information asymmetry, which is caused by lack of information on the part of the VCs, and which can lead to the added risks of adverse selection and moral hazard. Four Australian VC firms were surveyed using a comprehensive open-ended questionnaire. A manual content analysis was employed to analyse the questionnaire responses. Consistent with prior research, the Australian VCs sampled are found to employ Berger and Udell' three steps of investment: selection, contracting and monitoring. Furthermore, the semi-formal selection step of the investment process is found to consist of three distinct stages: deal sourcing, screening and evaluation. A number of techniques are used to minimise the risks of information asymmetry during the screening and evaluation stages, as well as during the later steps of contracting and monitorin.     

CEO stock options and analysts’ forecast accuracy and bias

This paper investigates the relationship between CEO stock options and analysts’ earnings forecast accuracy and bias. A higher level of stock options may induce managers to undertake riskier projects, to change and/or reallocate their effort, and to possibly engage in gaming (such as opportunistic earnings and disclosure management). These managerial behaviors result in an increase in the complexity of forecasting and hence, less accurate analysts’ forecasts. Analysts’ optimistic forecast bias may also increase as the level of stock options pay increases. Because forecast complexity increases with stock options pay, analysts, needing greater access to management’s information to produce accurate forecasts, have incentives to increase the optimistic bias in their forecasts. Alternatively, a higher level of stock options pay may lead to improved disclosure because it better aligns managers’ and shareholders’ interests. The improved disclosure, in turn, may result in more accurate and less biased analysts’ forecasts. Our empirical evidence indicates that analysts’ earnings forecast accuracy decreases and forecast optimism increases as the level of CEO stock options increases. This evidence suggests that the incentive alignment effects of stock options are more than offset by the investment, effort allocation and gaming incentives induced by stock options grants to CEOs.     

Herstellung von Wettbewerb durch Übertragung der Alterungsrückstellung in der Privaten Krankenversicherung

The system of individual prospective aging reserve enables the insured persons irrespectively of their individual risk to change their Private Health Insurance. Besides the presentation of an implementation concept it is shown that there is no inducement to miscalculate the extent of the individual prospective aging reserve on purpose.
