The influence of regional economic growth on migration may also differ by age and generation age due to individual lifestyle. Therefore, this study analyzes an effects of changes in regional economic growth on migration between regions by age group. The result shows that the increase in the growth rate of the regional economy and job creation increased the net migration rate, regardless of age group. Second, it is found that the growth rate of the regional economy and job creation have a greater effect on the net migration rate for the youth population than for the middle-aged group. Third, it is found that the gap between regions in the level of individual income in the 25 to 29 years old and the level of land price fluctuations in the 40 to 64 years old affect the net migration rate. This implies that regional economic growth is still an important factor in the migration between regions, and has a great influence on the youth population.

The purpose of this study is to analyze the effect of policy boosting fertility and labor participation rate on potential GDP growth rate. To do this, we employ a growth accounting approach, which decomposes per capita GDP into two parts. The first one is the change of dependency ratio and the other is the change of labor input. The labor input is again decomposed into the qualitative and quantitative parts. The quantitative part considers the change of labor participation rate and working time. The qualitative aspects is based on the trend of productivity of labor. From the scenarios of NSO(National Statistics Office), the effect of the fertility-raising policy on per capita potential GDP growth rate is calculated and projected to the year of 2050. We also forecast the policy effect inducing high labor participating rate of female labor and beyond 55-year old labor. The baseline results show that the per capita GDP growth rate will show mid 4% to the year of 2010, gradually declining to 3.94% by 2020, 3.03% by 2030, 2.41% by 2040. The high fertility rate scenario will not have effects on the potential growth by 2030, but show 0.10%p higher per capita GDP growth rate than that of baseline scenario result. By the high female labor participation policy, the per capita GDP growth rate will reach 0.04%p higher per capita GDP growth rate than that of baseline scenario. Based on the results of this paper, we conclude that the quantitative labor input cannot solely account for the trend decline of potential GDP, and the qualitative aspect, like labor productivity, is much more important element to sustain and boots the economic growth.

식민지 시기 조선의 인구동태는 한반도 안과 밖에서 역동적으로 진행되었다. 한편으로 자연성장률이 크게 성장하였고, 국내외 이동도 활발하게 이루어졌다. 이 연구는 식민지 시기 동안 정확히 얼마만큼의 조선인의 인구성장이 이루어졌고, 그 동태의 특성은 무엇인가를 밝히고 있다. 식민지 조선 인구 동태의 중요한 특성은 무엇보다 조선 안에서의 완만하거나 정체된 인구성장과 대비하여 만주와 일본에서의 조선인의 급속한 증가로 요약할 수 있다. 식민지 시기 조선내 인구의 자연성장율은 1910년-1915년 사이 10.57%o에서, 1935-1940년에는 20.4%o, 1940-1944년에는 24.4%o로 증가하였다. 그런데 식민지 시기 자연성장율이 실질적으로 크게 증가했음에도 불구하고 조선 내 인구성장이 1930년대 중반부터 떨어지고 이후 정체되었다. 이는 많은 인구가 만주와 일본에 이출한 때문이다. 식민지 기간 동안 조선의 인구는 1,260만 여명이 증가하였는데 그 중 약 69%인 870 만여 명이 한반도 안에 있고 31%가 만주와 일본으로 유출되었다. 집단적인 디아스포라의 경험은 해방 이후의 정치 역학과 사회 구성에 중요한 영향을 미쳤다. 또한 귀환하지 않은 해외 조선인들의 국적과 민족 정체성을 둘러싼 긴장은 지금도 해결되지 않고 있다.

The study tries to shed empirical light on the relation between the concentration of population in the primary city and per capita economic growth of the country, using the data for 113 nations over the period, 2000-2010. The concentration of population is measured in two ways, the ratio of the primary city's population to the total and to the second city. Using the ratio of the primary city's population to that of the entire nation, the empirical results neither show the robust negative relations nor the reverse U relation between primary city's concentration and economic growth. The ratio of the primary city to the second city however turns out to have a negative relation to per capita GDP growth. This result implies economic growth of a nation can be enhanced by decreasing the gap between the primary and the second ranked cities and does not support the reverse U hypothesis by Handerson(1974, 2003).

Over the past 30 years, Korea experienced demographic transition which typically substitutes quality(education) for quantity(number) of population. This paper decomposed labor supply into quantity and quality aspects and estimated the respective employment elasticities of economic growth in the past. Then, based on the assumptions about the future population (by age, sex and education) and labor force participation rates, the future labor supply(both quantity and quality) is projected and growth potential of the Korean economy is evaluated. The result shows that labor supply in Korea is relying gradually more on the qualitative rather than the quantitative aspect but since the increase in the former will not fully compensate the decrease in the latter, the potential growth rate of the Korean economy will be substantially reduced in the futrue.

Environmental condition can induce changes in early life-history traits in order to maximise the ecological fitness. Here I investigated how temperature change and variation in human aquatic activity/behaviour affect early life-history consequences in fish using a dynamic-state-dependent model. In this study, I developed a general fish's life-history model including three life-history states depend-ing on foraging activity, such as body mass, mass of reproductive tissue (i.e., gonadal development) and accumulated stress (i.e., cellular or physiological damage). I assumed the level of foraging activity maximises reproductive success-ultimately, fitness. The model predicts that growth rate, development of reproductive tissues and damage accumulation are greater in higher temperature whereas higher human aquatic activity rapidly reduced the growth rate and development of reproductive tissue and increased damage accumulation. While higher foraging activity in higher temperature is less affected by human aquatic activity, the foraging activity in lower temperature rapidly declined with human aquatic activity. Moreover, lower survival rate in higher temperature or human aquatic activity was independent on mortality rate due to human aquatic activity or mortality rate when foraging activity, respectively. However, the survival rate in lower temperature or human aquatic activity was dependent on these mortality rates. My findings suggest that including of early life-history traits in relation to climate-change and human aquatic activity on the analysis may improve conservation plan and health assessment in aquatic ecosystem.

This study analyzes the effects of localities' competitiveness which can contribute to employment growth in industries, on economic development in the local jurisdictions. For this analysis, such competitiveness is measured by competitive shares calculated from the application of a shift-share method to the employment growth in industries each locality witnessed over the 1990s. And we use annual population growth rate and average annual per capita income (substituted by per capita head tax derived from income tax) of the early 2000s as variables of local economic development. The analysis targets 167 local jurisdictions in Korea for the employment growth in industries, and is mainly placed in a spatial econometric setting. The results of analysis are as follows : The competitive share of manufacturing has the effect of increasing annual population growth rate whereas that of construction has a negative effect on the population growth rate. As well, the competitive shares of manufacturing and of construction negatively influence average annual per capita income while that of community, social and personal services positively affects the income.

Using an unobserved components model that features trend growth as a random walk, we find that GDP trend growth rates had gradually declined from the late 1980s to early 2010s in Korea. To uncover the underlying features of the slowdown, we use trend growth accounting. A major feature appears to be a significant decline in the growth rate of labor productivity. To be specific, the first gradual decline in trend growth, which started in 1988 and continued to 1998, is associated with a drop in TFP measured in labor-augmenting units. This finding is inconsistent with the hypothesis that the slowdown in GDP trend growth can be attributed to the 1997-1998 Korean financial crisis. Sluggish investment growth is behind the second period of the gradual slowdown, from 2002 to 2012.

1994년부터 10년동안 베트남의 통신 보급률을 살펴 보면 베트남 국민들이 어떤 것을 좋아하는 지 알 수 있다. 정확히 표현하자면, 베트남 젊은이들의 IT에 대한 관심의 수치라 할 수 있을 것 같다. 특히 아직까지 전체 인구대비 5% 수준에 머물고 있지만 무선통신 서비스(238배)와 인터넷에 대한 성장률(621배)은 가히 폭발적이라 할 수 있다. 이러한 통신 환경의 폭발적인 성장은 베트남이 1986년 ‘도이모이(혁신)’로 일컬어지는 개혁.개방정책을 채택하면서 이루어지고 있다.
