The purpose of this article is, first, to argue that the fertility cannot be reduced rapidly through widerspread diffusion of contraceptive practices which has been the main drive of the national policy in population control, because there involves the inescapable externalites in procreation, second, family sizes tend to be larger because of the financial externalities arising from government subsidies to families with children, and finally, the decreasing relative risk aversion of households with wealth may induce the poor to have large family sizes.

This study investigated the factors influencing the fear of failure in starting a business among the MZ generation(Millennials and Generation Z). The research focused on financial, psychological, and behavioral factors affecting this fear of failure and employed empirical analysis using structural equation model on data collected from 200 members of the MZ generation. Key findings included: Financial factor(lack of accessible finance) significantly increased the fear of startup failure. Psychological factors(aversion to risk and aversion to stress) also significantly contributed to the fear of failure. The influence of behavioral factor(aversion to hard work) on fear of failure was not statistically significant. Among these, aversion to stress had the strongest impact, followed by aversion to risk and lack of accessible finance. Fear of startup failure was found to have a significant negative effect on the intention to start a business among the MZ generation. Furthermore, fear of startup failure mediated the relationship between psychological factors(aversion to risk and aversion to stress) and behavioral factor(aversion to hard work) and entrepreneurial intention. However, the mediating effect between financial factor(lack of accessible finance) and entrepreneurial intention was not tested. These findings contributed academically by offering a more detailed analysis of factors affecting entrepreneurial intentions compared to previous studies. Practically, the results suggested ways to mitigate the fear of failure to enhance the entrepreneurial intentions of the MZ generation.

This paper derives an equilibrium asset price when there exist three kinds of traders in financial market: a risk-averse informed trader, noise traders, and risk neutral market makers. This paper is an extended version of Kyle's (1985, Econometrica) continuous time model by introducing insider's risk aversion. We obtain not only the equilibrium asset pricing and market depth parameter but also insider's value function and optimal insider's trading strategy explicitly. The comparative static shows that the market depth (the reciprocal of market pressure) increases with time and volatility of noise traders' trading.

Government initiatives are continuously being invested to nurture supporting business environment for small and medium sized enterprises (SMEs), such as government-support ERP systems project for SMEs. As such, scholars need to pay attention to SMEs can successfully adopt and manage government-support ERP systems. This study, therefore, conceptually developed and tested a research model for understanding what factors influence SMEs' intention to adopt government-support ERP systems. We obtained thirty samples from SMEs, which is organizational level, and data were analyzed using the partial least square (PLS) technique. The results of data analysis found that institutional pressure and resource dependence had positive effects on the adoption of government-support ERP systems. On the other hand, risk aversion of SMEs was found to have negative effects to adopt government-support ERP systems.

This paper is the data analysis of exercise patterns of ESOs and primary factors that influence on their early exercise. ESOs are prematurely exercised soon after the vesting period is over and it is argued that risk aversion, profitability through exercise, firm characteristics and behavioral factors influence on such early exercise patterns. This paper examined 111 previously-exercised stock options that had been granted to 3,267 employees from year 2000 to year 2006, and analyzed the early exercise patterns and their primary factors. The result shows that stock options were exercised approximately 3.15 years after being granted, and 0.37 year after the vesting period was over. Such an early exercise pattern was found to be influenced by risk aversion, profitability and firm characteristics.

This note examines a situation where a risk-neutral insurer and a risk-averse individual (prospective insured) negotiate to reach an arbitration point of the price of insurance over the terms of an insurance contract in order to maximize their respective self-interests. The situation is modeled as a Nash bargaining problem. We analyze the dependence of the price of insurance, which is determined by the Nash solution, on the parameters such as the size of insured loss, the probability of a loss, the degree of risk-aversion of the insured, and the riskiness of loss distribution.

Previous researches on risk attitudes or on the typical utility functions have mostly focused on how the risk attitude of decision maker varies when changes are made in one or two lottery reference points such as consequence domain and magnitude of probability under assumed risk situations represented by simple lotteries. It is, however, very difficult to forecast dominant risk attitudes under risk situations which exhibit a complex combination of many reference points. In this study, twelve risk situations which a decision maker may confront in real decision-making situations were formulated by combining in various ways three reference points, that is, magnitude of probability, consequence domain, and magnitude of gain or loss. Then through a questionnaire dominant risk attitudes under every assumed risk situation were investigated, and the general shape of utility function implied by the experimental results were derived. Results of the present study show that none of the three reference points have dominant effect over the others due to complicated interaction between them, and given the twelve risk situations the observed risk attitude widely varies from strong risk taking to strong risk aversion.

I consider the optimal consumption and portfolio selection problem with nonnegative wealth constraints using the dynamic programming approach. I use the constant relative risk aversion (CRRA) utility function and disutility to derive the closed-form solutions.

I use the dynamic programming approach to study the optimal consumption and investment problem with regime-switching and constant labor income. I derive the optimal solutions in closed-form with constant absolute risk aversion (CARA) utility and constant disutility.
