Purpose - For the past several decades, behavioral economics or behavioral decision theory has undergone rapid development. This study provides a critical review of the development of behavioral economics with a focus on what are deemed to be core theories in the field. Starting from the utility function proposed by Daniel Bernoulli in the 18th century, the development history of utility functions until the emergence of the prospect theory is thoroughly reviewed. Some of the experimental results violating the traditionally assumed utility function and supporting the prospect theory value function are summarized. The most representative principles of rational choice are transitivity, independence from irrelevant alternatives (IIA), and regularity. The development of behavioral economics has been triggered by finding counter-examples to these principles. Some of the choice behaviors discussed in this study as counter-examples to the traditional theories of rational choice are the St. Petersburg paradox; the Allais paradox; gambling behavior; and the various context effects including the similarity effect, attraction effect, and the compromise effect. The Elimination-by-Aspects (EBA) model, which was proposed as an explanation for the similarity effect, is discussed in detail as well. Based on the literature review and further analysis, this study summarizes the relationship between the context effects, prospect theory, and EBA model. Research design, data, and methodology - This study provides an extensive literature review on several important theories in the field of behavioral decision theory and adds some critical comments to the theories and the relationships among them. This study first reviews the development of utility functions. Daniel Bernoulli introduced the concept of utility function to solve the St. Petersburg paradox. In the mid-20th century, Herbert Simon proposed the "satisficing" heuristic and presented a value function with a shape different from traditional utility functions. This study highlights the strengths and weaknesses of several utility functions proposed until the emergence of the prospect theory value function. Results - This study posits that prospect theory and EBA model are the two most important theories in the field of behavioral decision theory. They can explain various choice behaviors that traditional utility maximization analysis has been unable to. The application of these models to various fields is further increasing nowadays. This study explains how prospect theory and the EBA model can be used to explain the context effects. Conclusions - The traditional economic theory relies on a single variable called "utility" in explaining consumer choice. However, this study argues that, in investigating consumer choice, several other variables should also be considered. These are the similarity among alternatives, an alternative's prototypicality within the category, the dominance relationship between alternatives, and the reference point in evaluating alternatives. Due to the development of behavioral economics, we are now closer to a more complete understanding of consumer choice behavior than in the past when we had only a single tool called utility.

IT산업의 인적자원에 대한 중요성과 관심은 증가하고 있으나 IT인력관리에 대한 체계적인 접근이 부족한 실정이며 국내 IT산업은 전문인력의 부족 및 우수인력들의 잦은 이직현상 등 여러 가지 문제점을 노출하고 있다. 본 연구에서는 IT인력을 대상으로 개인특성과 조직특성이 경력만족, 경력전망 및 경력몰입에 미치는 영향을 연구하였다. IT 인력의 경력몰입을 실증적으로 연구하기 위해 국내 IT관련 업체에 종사하고 있는 개발자 및 전산실 직원들을 대상으로 설문조사를 실시하였다. 분석결과, 개인특성 중 자아존중감이 경력만족에 가장 큰 영향을 미치는 것으로 나타났으며 조직특성 중에서는 분배공정성 및 성장기회제공 등에 대한 지각 정도가 높을수록 경력전망에 유의미한 영향을 미치는 것으로 나타났다. 하지만 경력계획과 경력관리는 IT인력의 경력몰입에 미미한 영향을 미치는 것으로 나타나 IT인력관리의 시사점을 제시하였다. 본 연구는 향후 국내 IT인적자원의 체계적인 관리에 기여할 것으로 기대된다.

An investigation was conducted to know a prospect of woody toy in Korea for physical, psychological and intellectual development. It was told that toys that stimulate cognitive development are appropriate for the child's capabilities, responsive to the child's movements, provide feedback when manipulated, and require imagination or fantasy. Toys particularly useful in the development of these abilities include dolls, figures, cuddly toys, puppets, costumes, and construction toys. Therefore, a toy is a wonderful object, indispensable to physical, psychological and intellectual development, both for those who have the capacity to integrate into society and for those who encounter difficulties. If we can replace a plastic toys by a environmental wooden toys, we can contribute to child development that is especially to promote creativity, artistic, problem-solving, language and social skills. In addition, we can support the ability of wood toy manufacturers to market their products in a responsible way and contribute to strengthen the competitiveness of our commodities on international markets.
