The purpose of this study was to identify the effects of wives' economic contributions and sex-role attitudes on couples' decision-making for use in family education and to improve stable couple relationships. This study targeted 286 married women who have a child or children. The main results of this study indicate that almost half of the participants showed that their couple decision-making, economic resource contributions and sex-role attitudes were husband-dominated. Additionally, the participants' most modern sex-role attitudes were toward gender stereotypes, though the most conservative attitudes were toward women and men's household lives. The variables that distinguished between husband-dominated and equality couples were age, education level, spouse's average income and resource evaluation; related, age, education level, spouse's average income, contribution toward household management and the occupational life of the woman were the variables that distinguished between husband-dominated and wife-dominated couples. This study also revealed the variables that affect couples' decision- making, demonstrating the necessity of considering several variables in the approach to the decision-making process of individual couples.

Human capital theory and social capital theory provide a framework for analyzing economic well-being. The purpose of this study was to investigate the effects of human capital and social capital on the economic well-being of the elderly. The data from the 1st wave of KLoSA (Korean Longitudinal Study of Aging) were used (n=3,426). The major findings were as follows: First, human capital and social capital are both resources that can contribute to increasing the economic well-being of the elderly. Second, the effects of human capital on the economic well-being of the elderly were relatively higher than the effects of social capital. Third, the relative contributions of human capital and social capital to increasing economic well-being varied by sex, age, and region. Based on the empirical results, the implications for social investment in human capital and social capital were provided.

We examine historical contributions of inter fuel substitution, changes in carbon efficiency and energy intensity, growth of economy and population to Korea's $CO_2$ emissions from 1970 to 1998 using the log mean weight Divisia index method. The study reveals that economic growth is the most significant factor to $CO_2$ emissions growth among the five factors. Changes in the fuel substitution and carbon coefficient are found negative contributors to $CO_2$ emissions growth. Energy intensity, which played dominant role in halting $CO_2$ emissions growth in the 1980s, began to play reversed role in the 1990s. When evaluated with the log mean Divisia index technique, deterioration of energy intensity in the 1990s is found worse and expected to contribute $CO_2$ emissions growth further.

본 연구는 자본과 노동의 요소투입물의 증가가 환경오염의 증가를 유발한다는 Byrne (1997)모형과 기술축적도 환경오염을 유발하는 Bovenberg and Smulders (1995)모형을 혼합한 이론적 모형을 구축하고 경제성장률 제약조건식을 도출하여 경제성장과 환경오염관련 변수 간의 관계를 실증분석하였다. 도출된 경제성장률 조건식에서 경제성장률은 상대적인 소비와 오염의 비효용이 감소할수록, 할인율이 감소할수록, 오염저감기술수준이 증가할수록, 기술생산성 파라메타가 증가할수록 증가함을 보였다. OECD 20개국 패널자료를 이용한 실증분석에서 노동생산성이나 총고정자본, 기술이전과 같은 성장관련 주요 변수들은 모두 유의한 것으로 나타나 경제성장 관련 기존의 연구결과와 다르지 않았다. 그러나 경제성장에 대한 환경오염변수의 추정계수가 유의한 값으로 나타나지 않아 이론적으로 도출한 경제성장률조건식의 설명에 한계가 있으나 오히려 환경쿠즈네츠곡선가설의 존재여부를 판단할 수 있는 실증분석 연구과제를 남기는 데 의미가 있다고 본다.

The demand for beef as a protein source is increasing worldwide, although in most countries beef accounts for considerably less than half of total meat consumption. Beef also provides a highly desirable eating experience in developed countries and, increasingly, in developing countries. The sustainability of beef production has different meanings in the various geographical and socio-economic regions of the world. Natural resources including land mass and uses, rainfall and access to livestock feed, and the robustness of the economy are major determinants of the perception of beef sustainability. In this overview of the 2016 International Symposium on "Future Beef in Asia" and this subsequent Special Edition of the Asian-Australasian Journal of Animal Sciences on "Current Situation and Future Prospects for Global Beef Production", the contributions have been grouped into the following categories: Countries in Southeast Asia; Europe; and Countries producing highly marbled beef for export and/or domestic consumption. They also include reference to Special Topics including marbled beef production, and use of "omics" technologies to enhance beef quality assurance. Among these broad categories, notable differences exist across countries in the production and marketing of beef. These reflect differences in factors including natural resource availability and climate, population size, traditional culture and degree of economic development including industrial and technological developments. We trust that the International Symposium and this Special Edition on Current Situation and Future Prospects for Global Beef Production, the contents of which that are briefly summarized in this paper, will serve as a valuable resource for the livestock industries, researchers and students with an interest in enhancing the prospects for sustainable, efficient beef production that satisfies the growing size and complexity of consumer demands and markets for beef.

In 2014, the United Nations Framework Convention on Climate Change (UNFCCC) agreed to submit the Intended Nationality Determined Contributions (INDCs) at the conference of parties held in Lima, Peru. Then, the South Korean government submitted the INDCs including GHGs reduction target and reduction potential on July, 2015. The goal of this study is to predict GHGs emission and to analyze reduction potential in agricultural sector of Korea. Activity data to estimate GHGs emission was forecast by Korea Agricultural Simulation Model (KASMO) of Korea Rural Economic Institute and estimate methodology was taken by the IPCC and guideline for MRV (Measurement, Reporting and Verification) of national greenhouse gases statistics of Korea. The predicted GHGs emission of agricultural sectors from 2021 to 2030 tended to decrease due to decline in crop production and its gap was less after 2025. Increasing livestock numbers such as sheep, horses, swine, and ducks did not show signigicant impact the total GHGs emission. On a analysis of the reduction potential, GHGs emission was expected to reduce $253Gg\;CO_{2-eq}$. by 2030 with increase of mid-season water drainage area up to 95% of total rice cultivation area. The GHGs reduction potential with intermittent drainage technology applied to 10% of the tatal paddy field area, mid-drainage and no organic matter would be $92Gg\;CO_{2-eq}$. by 2030.

This article is to analyse the economic efficiency of capital market, which plays a role of resource allocation in terms of financial claims such as stock and bond. It provides various contributions to the welfare theoretical aspects of modern capital market theory. The key feature that distinguishes the theory described here from traditional welfare theory is the presence of uncertainty. Securities has time dimensions and the state and outcome of the future are really uncertain. This problem resulting from this uncertainty can be solved by complete market, but it has a weak power to explain real stock market. Capital Market is faced with the uncertainity because it is a kind of incomplete market. Individuals and firms in capital market made their consumption-investment decision by their own criteria, i. e. the maximization of expected utility form intertemporal consumption and the maximization of the market value of firm. We noted that allocative decisions that had to be made in the economy could be naturally subdivided into two groups. One set of decisions concerned the allocation of first-period resources among consumption $C_i$, investment in risky firms $I_j$, and riskless investment M. The other decisions concern the distribution among individuals of income available in the second period $Y_i(\theta)$. Corresponing to this grouping, the theoretical analysis of efficiency has also been dichotomized. The optimality of the distribution of output in the second period is distributive efficiency" and the optimality of the allocation of first-period resources is 'the efficiency of investment'. We have found in the distributive efficiency that the conditions for attainability is the same as the conditions for market optimality. The necessary and sufficient conditions for attainability or market optimality is that (1) all utility functions are such that -$\frac{{U_i}^'(Y_i)}{{U_i}^"(Y_i)}={\mu}_i+{\lambda}Y_i$-linear risk tolerance function where the coefficients ${\mu}_i$ and $\lambda$ are independent of $Y_i$, and (2) there are homogeneous expectations, i. e. ${\Large f}_i(\theta)={\Large f}(\theta)$ for every i. On the other hand, the efficiency of investment has disagreement about optimal investment level. The investment level for market rule will not generally lead to Pareto-optimal allocation of investment. This suboptimality is caused by (1)the difference of Diamond's decomposable production function and mean-variance valuation model and (2) the selection of exelusive investment or competitive investment. In conclusion, this article has made an analysis of conditions and processes of Pareto-optimal allocation of resources in capital marker and tried to connect with significant issues in modern finance.

최근 기업 경영에 있어 정보기술의 도입 및 전략적인 활용은 선택이 아닌 필수로 자리잡고 있다. 기업의 전략적인 목표와 정보기술 간의 상호 의존은 기업의 생존 및 성장에 중요한 역할을 하고 있으며, 이에 따라 이미 많은 기업이 지속적으로 정보기술에 투자하고 있다. 정보기술 투자 성과 관련해서는 기업 내부의 요인들과 전략들, 기업외부의 고객까지 여러 가지 복합적인 요소들이 서로 상호작용하고 있기 때문에, 각 요인들을 독립적으로 분리하여 정보기술 투자 성과에 미치는 영향력을 분석하는 것이 쉽지 않다. 이에 본 연구는 기존의 연구들을 바탕으로 정보기술 투자성과에 영향을 줄 수 있는 변수들을 도출하여, 각 변수들의 관계를 수리적인 모델링을 통해 단순화시키고, 시뮬레이션 방법론을 이용하여 각 변수들의 변화에 정보기술 투자 성과는 어떻게 달라지는지를 밝혔다. 본 연구의 결과는 정보기술 투자는 서비스의 품질을 증가시켜 경제학적인 성과들에 간접적으로 영향을 주고, 정보기술 투자와 동시에 소비자 잉여는 증가되지만, 큰 투자비용으로 회사의 이익은 감소하게 된다. 그리고 시간이 지남에 따라 품질 증가에 관한 정보가 고객들 사이에 퍼져 나가게 되므로 최종적으로 기업의 수익을 증가시켜준다. 또한, 정보기술 투자 성과 극대화를 위해서는 회사가 제공하는 서비스와 소비자들의 네트워크 효과 등이 고려되어 정보기술 투자 여부를 결정하고, 회사에 맞는 정보기술 투자 전략을 세워야 함을 시뮬레이션 모형을 통해 확인할 수 있었다. 구체적으로, 한 번에 많은 투자를 할 경우는 단기적인 성과는 클 것으로 기대되나, 장기적으로 좋은 성과가 이뤄지지 않는다. 그러나 정보의 확산 속도가 빠르거나 정보의 장벽이 될 수 있는 정보를 받지 못하는 소비자가 적을 경우 단기에 집중 투자 하는 것이 많은 수요를 얻을 수 있다. 또, 여러 번에 걸쳐 투자하는 경우는 적당한 주기를 가지게 될 경우 장기적으로 큰 성과를 낼 수 있음을 확인할 수 있었다. 본 연구는 경제학 모델링과 시뮬레이션을 결합시켜, 각각의 한계를 모두 극복할 수 있는 방법론을 활용했다는 측면과, 정보기술 투자의 성과를 제품 품질의 매개 효과 모형에 적용하여 정보기술 투자와 기업 성과간의 관계를 보여주었다는 측면, 마지막으로 정보기술 투자 전략 및 정보의 확산 효과를 반영하여 정보기술 투자의 성과를 확인할 수 있다는 측면에서 의의가 있다.
