The Schwabe's law explains the housing demand weighs more on demographic factors rather than on socio-economic factors as societies achieve higher level of economic development. Based on Schwabe's law, the present study constructs a hypotheses to analyze changes of housing demand with respect to housing tenure change in Seoul Metropolitan Area (SMA) during the periods of 1980 to 2005. To test the hypotheses, the authors take advantage of the Population and Housing Census 2% data from 1980 to 2005. The authors apply binary probit with decomposition method to verify our hypotheses. The authors found that the influence of socio-economic factors on housing tenure have been weakened in the housing market during the periods of 1980 to 2005. On the other hand, the relative influence of demographic factors have been strengthened in the housing market during the periods. The present study concludes that housing demand in the SMA have been dramatically changed from socio-economic characteristics to demographic factors to decide housing tenure during the periods, which confirms the hypotheses of the present study.

The sharing economy, which maximizes the value of resources by sharing, is appearing in various sectors today and is gradually expanding with the development of ICT. This study identified factors affecting the intention to use the services of the sharing economy with a focus on the sharing accommodation platform services. As the intention to use the sharing economy service is divided into the intention to use as a taker(guest) and a provider(host), those influencing factors were analyzed respectively. Results showed that collaborative norm, economic benefit and honorary compensation affected the intention to use as a guest. Openness to experience, economic benefit, and honorary compensation increased the intention to use as a host. Economic benefit made a greater impact on the intention to use as a guest, while honorary compensation enhanced the intention to use as a host.

This study investigates the effects of economic factors and forest environments on rural residential area development in seven north central states of the U.S. by focusing on the relative importance of not only economic factors but also forest environments by forest type as core drivers of residential development. An empirical model of locations and magnitudes of population changes since 1950 in the north central region is first constructed, and then a panel model with fixed effects for counties is used to explain population growth by age group over time at the county level. Then a set of three equations is estimated for three major age groups, and a cross-sectional model is estimated for the last time period that regresses county-level environmental amenity variables on fixed effects coefficients for counties. Finally, an equation explaining changes in rural housing density is estimated. The results imply that immigrant age is a key factor influencing the choice of the place of residence and that the effects of environmental amenity factors on population growth and subsequent housing development in a county vary according to the age group.

동아시아 경제권의 국가들 중에서도 한국과 중국의 잠재적 기업가정신을 측정하고 양국 잠재적 기업가정신에 영향을 미치는 문화적 요인에 대해 비교하고자 하였다. 이를 위해 잠재적 기업가라고 여길 수 있는 한국과 중국의 대학생들을 대상으로 하여 설문조사를 실시하였다. 210명의 한국 대학생들과 157명의 중국 대학생들이 본 설문에 응하였다. 설문은 크게 두 가지 영역으로 구분되어 있는데, 개인의 기업가적 지향성을 측정하기 위한 질문과 개인의 기업가적 성향에 영향을 주는 문화적 요인들을 측정하는 질문으로 나누어져 있다. 개인의 기업가적 지향성을 측정하기 위하여 자기통제력(Locus of Control)과 혁신성(Innovativeness)을 묻는 세부 질문을 만들었고, 문화적 요인을 측정하기 위해서 대학생들이 느끼는 경제적자유(Economic Freedom), 개인주의(Individualism) 그리고 불확실성 회피성(Uncertatinty Avoidance)의 정도를 묻는 질문을 만들어 설문을 실시하였다. 첫 번째 연구가설은 '한국의 대학생들이 경제적 자유, 개인주의, 불확실성 회피성이 더 높다고 인식한다'이며, 두 번째 연구가설은 '경제적 자유가 보장되고 더 개인주의적인 문화에서 기업가적 성향이 더 높게 나타나며 확실성 회피성이 높을수록 기업가적 성향은 더 낮게 나타난다, 세 번째 연구가설은 '한국 대학생들의 기업가적 지향성 정도가 중국 대학생들의 그것보다 더 높다'이다. 설문조사는 가설과는 다른 결과를 보여주고 있다. 중국의 대학생들이 한국의 대학생들 보다 자국의 문화에 대해 더 경제적 자유가 보장되며 개인주의적이라는 인식을 가지고 있었다. 불확실성 회피성에 있어서는 가설과 동일하게 중국 대학생들보다 한국의 대학생들이 자국에 대해 불확실성 회피성이 더 높다고 인식하고 있다. 또한 양국의 대학생들은 기업가정신 형성에 있어서 각각 다른 문화적 변수에 의해서 영향을 받는다는 사실을 알 수 있었다. 한국의 대학생들은 경제적 자유의 정도에 의해 영향을 받으며, 중국의 대학생들은 불확실성 회피성에 의해서 영향을 받는다. 마지막으로, 세 번째 가설과 달리 기업가적 지향성은 중국의 대학생들이 한국의 대학생들보다 더 높은 수치를 보인다. 혁신성에 있어서는 양국 대학생들 간의 유의한 차이를 발견하기 어려웠으나 내재적 통제력에 있어서 중국의 대학생들은 한국의 대학생들보다 높은 수치를 나타냈다.

The Korean economy has achieved continuous economic growth for the past several decades thanks to the government's export strategy policy. This increase in exports is playing a leading role in driving Korea's economic growth by improving economic efficiency, creating jobs, and promoting technology development. Traditionally, the main factors affecting Korea's exports can be found from two perspectives: economic factors and industrial structural factors. First, economic factors are related to exchange rates and global economic fluctuations. The impact of the exchange rate on Korea's exports depends on the exchange rate level and exchange rate volatility. Global economic fluctuations affect global import demand, which is an absolute factor influencing Korea's exports. Second, industrial structural factors are unique characteristics that occur depending on industries or products, such as slow international division of labor, increased domestic substitution of certain imported goods by China, and changes in overseas production patterns of major export industries. Looking at the most recent studies related to global exchanges, several literatures show the importance of cultural aspects as well as economic and industrial structural factors. Therefore, this study attempted to develop a forecasting model by considering cultural factors along with economic and industrial structural factors in calculating the import volume of each country from Korea. In particular, this study approaches the influence of cultural factors on imports of Korean products from the perspective of PUSH-PULL framework. The PUSH dimension is a perspective that Korea develops and actively promotes its own brand and can be defined as the degree of interest in each country for Korean brands represented by K-POP, K-FOOD, and K-CULTURE. In addition, the PULL dimension is a perspective centered on the cultural and psychological characteristics of the people of each country. This can be defined as how much they are inclined to accept Korean Flow as each country's cultural code represented by the country's governance system, masculinity, risk avoidance, and short-term/long-term orientation. The unique feature of this study is that the proposed final prediction model can be selected based on Design Principles. The design principles we presented are as follows. 1) A model was developed to reflect interest in Korea and cultural characteristics through newly added data sources. 2) It was designed in a practical and convenient way so that the forecast value can be immediately recalled by inputting changes in economic factors, item code and country code. 3) In order to derive theoretically meaningful results, an algorithm was selected that can interpret the relationship between the input and the target variable. This study can suggest meaningful implications from the technical, economic and policy aspects, and is expected to make a meaningful contribution to the export support strategies of small and medium-sized enterprises by using the import forecasting model.

Various kinds of living circumstances are making population structure of Korean changed. That is, number of the children is decreased and that of the aged is increased. It is predicted that population of the children and the aged will be almost same until 2020. With above, as the expectation of the aged on healthy living might be increased, some special programs for the aged will be needed strongly. At this point, Korean aged population might be economically poor, comparing with other generation. In general, economic factor affects the subjective living-satisfaction and health status of them. Moreover, educational status, household shape and family tieing also affect their health status. According to the foreign articles, health status of the aged might be related to income, educational status, job, employed or/not, marital status, family structure, sex, and childhood condition. decrease of the income or unemployment could make the death rate of the aged higher. During childhood, discordance among the family might affect their health status after. IGUR is also important factor to affect the adulthood health. Positive life style of the aged would lessen their unequality of the health among them. Nutritional status of the Korean aged population might be indicated under the nutritional recommendation. It is affected by their income, education level, social class, and residing place. (Korean J Nutrition 33(1) : 86-101, 2000)
