Non-market valuation studies tend to assume that individual households have homogeneous preferences for a non-market good to value. However, since the preferences for non-market goods, especially environmental goods are more likely to be heterogeneous by nature, it may be more appropriate to assume heterogeneous preferences for non-market goods, which may in turn may lead to reduced biases in the WTP estimation. This study investigate the extent to which individual households have heterogeneous preferences for reduced concentrations of radon, a radioactive indoor air pollutant, for road safety, and for nuclear power safety. We also analyze the effect of heterogeneity assumption on the results of model and WTP estimation. Using the choice experiments and mixed logit models, we found that allowing for heterogeneous preferences improved model fitness and that there existed heterogeneous preferences for both reduced radon concentration and road safety, albeit not for nuclear power safety. The mean WTP for reduced radon concentrations and road safety increased by factors of 2.44 and l.74 respectively with the models allowing for heterogeneous preferences.

I constructed the 2003 Korean 'social accounting matrix'(SAM) to analyze the multipliers of total demand for each economic activity. I find that the relative magnitude of the influence of the welfare policy to the national economy measured by input-output production multipliers tends to be underestimated compared to SAM multipliers. This is because the total demand multipliers of SAM include the private sector effects, which is not considered in the input-output model. The result also support that income inflows in public service areas including education, health and social work, generate gains in the relative income of households.

Using the 2007 Fund Investors Survey, we investigated (1) the differences in economic status in terms of household income, consumption, saving, assets and debts, (2) the differences in financial management behavior, (3) and the differences in confidence in economic status after retirement between households conducting and not-conducting financial preparation for retirement. The major study findings were as follows. First, only 46.4% of the households were financially preparing for retirement. The levels of income, consumption, and saving were higher among households conducting financial preparation for retirement than among those not-conducting such financial preparation. Second, households conducting financial preparation for retirement had a relatively high propensity to save. Their financial asset portfolio had a higher weight in safety assets and investment assets than in retirement assets. Due to their lack of confidence in their economic status after retirement, their demand for financial preparation for retirement remained. Third, the households which did not conduct financial preparation for retirement tended to have a relatively heavy debt burden and not to implement general household financial management practices. Fourth, among the three-pillar retirement income system, the second pillar, of individual retirement account was not well established. Based on these results, various implications were suggested.

기후변화, 고령화 사회로의 진입, 4차 산업혁명에 의한 첨단기술의 확산 등은 기업 현장에 큰 영향을 주고 있다. 또한, 최근 2년 넘게 지속되고 있는 코로나 팬더믹, 미중 갈등과 우크라이나 사태로 촉발된 원자재 가격 급등과 수급 불안은 세계 경제를 불황으로 몰고 있다. 중소기업을 창업하여 경영하고 있는 최고경영자(이하, CEO)들은 이러한 사업환경의 변화 속에서 지속가능 경영을 고민하고 있다. 흥미로운 것은 가혹한 사업환경을 마주하여 사업을 중단하고 정리하려는 CEO가 있는 반면, 의지를 갖고 사업을 계속하려는 경영자들도 있다는 것이다. 본 연구의 목적은 중소기업 CEO의 사업계속의도에 영향을 미치는 요인들을 조사하고 분석하는 데 있다. 본 연구에서는 중소기업의 사업 전망, 기업 역량, 경영자 역량, 가계 경제에 대한 부담감, 사업승계 인식이 CEO의 사업계속의도에 미치는 영향에 관한 연구를 진행하였다. 따라서 본 연구에서는 중소기업의 사업 전망, 기업 역량, 경영자 역량, 가계 경제에 대한 부담감, 사업승계 인식이 CEO의 사업계속의도에 어떠한 정도로 영향을 미칠 것인지 양적 연구를 통해 실증적으로 검증하고자 한다. 변화무쌍한 경영 환경하에서 창업하여 일군 중소기업을 경쟁력 있게 성장시키기 위해 우선시 요구되는 CEO의 사업계속의도(Intention to Continue Business)를 종속변수로 설정하여 본 연구를 진행하였다.

향후 기후변화협약과 같은 환경규제의 강화가 예견되는 상황에서 에너지산업은 상당한 정책변화를 겪게 될 것으로 예상된다. 이러한 정책수립과 결정과정에서 본 연구는 천연가스산업에 대한 정책변화 효과를 분석할 수 있는 일반균형 분석모형을 제시함으로써 천연가스산업에 관한 유용한 정보를 제공할 수 있을 것으로 기대된다. 소국경제를 가정한 연산가능 일반균형모형(CGE)을 통해 분석된 천연가스산업의 거시경제적 파급효과를 살펴보면 다음과 같다. 먼저, 천연가스 가격이 5% 상승하였을 경우에는 실질GDP가 0.031% 감소하고, 생산자 물가지수는 0.051% 상승하였다. 가계수요가 10% 증가한 경우와 투자가 10% 증가한 경우에는 실질 GDP가 각각 0.002%씩 상승하고 생산자 물가지수는 0.008%와 0.004% 상승하는 것으로 나타났다. 이러한 분석결과는 천연가스산업이 비교적 거시경제에 미치는 영향이 적은 것을 보여 주고 있다.

The purpose of this study is to analyze the effects of household income drops on household economic status during economic crisis periods. Using the data taken from Korean Household Panel Study for 1996 and 1998, it was investigated how household income change affected household income, expenditure, and assets/debt. The economic status change of the income-decreased group was compared with that of the income-increased group. The major findings were as follows: Average income of the total sample was 1,905 thousand won in 1996, while 1,419 thousand won in 1998. The household of which income was decreased during the period was 65.1% of total sample. Average income of the group was reduced from 2,263 thousand won to 1,239 thousand won. Among income sources, the amount of income from real asset was found to be the highest decreasing rate, and the amounts of both business and employed-work income were reduced almost up to an half of those in two years ago. The amounts for all expenditure categories were also decreased with decreasing household income. Especially the expenditures for food away from home, leisure, durable, recreation, and vehicle-related expense were found to have the highest income elasticity. The households with decreased income were found to reduce household expenditures by 377 thousand won per month, which was 70.9% of that in 1996. Decreases in household income resulted in decreases in net wealth by 10,170 thousand won. With decreases in household income, the amounts of total insurance and private savings such as gye were decreased, and so were the amounts of real assets and monetary assets.

The purpose of the study was to investigate the characteristics and economic status of deficit households compared to surplus households. Data from The Household Income and Expenditure Survey 2005 by NSO and 50, 207 salary/wage earners' households were used for the analysis. The statistical methods used were GLM, logit, and cluster analyses. The analysis results showed that 25.3 percent of the households were deficit households. Approximately half of the lowest 20% income group were deficit households. Income deficit households earned 1, 273 thousand less than that of surplus households, whereas consumption of deficit households was 1, 006 thousand more than that of surplus households. The average propensity of consumption of deficit households was 142.1. According to the logit analysis, factors contributing to the probability of belonging to a deficit household included income level, household size, age and educational level, occupation, homeownership, car ownership, and wife's employment status. Deficit households were classified into 5 types: 1) health care expenditure-dominated group, 2) housing expenditure-dominated group, 3) education expenditure-dominated group, 4) money transfer-dominated group, and 5) overall-overconsumption group. The overall-overconsumption group was the largest group of all at 58.5%. It was found that for all five groups, the changes in household size, income group, home ownership, and occupation of the individual were variables that influenced the probability of belonging to a certain group.
