Household debt in Korea raises concerns about the resilience of the economy due to its size and quality. Against this backdrop, we investigate if household leverage matters for private consumption in adverse economic environments even without severe financial disruptions. We find that the balance sheet positions in terms of the leverage ratio may weaken consumption growth. We also find that the depressive effect of debt on consumption may differ across types of consumer spending and household characteristics. In particular, the effects of indebtedness have been much stronger in relation to durable goods expenditures than in other areas. In addition, debtors in high-income (wealth) groups have also shown downward adjustments in consumption even more so than low-income (wealth) groups. These findings imply that debtors' precautionary behavior may serve as an important channel from leverage to consumer spending.

Due to the rapid advancement of technologies, a growing number of innovative products with a short life-cycle have been introduced to the market. As the life-cycles of such products are shorter than those of durable goods, the demand variation during the life-cycle adds to the difficulty of inventory management. Traditional inventory planning models and techniques mostly deal with products that have long life-cycles. The assumptions on the demand pattern and subsequent solution approaches are generally, not suitable for dealing with products with short life-cycles. In this research, inventory replenishment problems based on the logistic demand model are formulated and solved to facilitate the management of products with short life-cycles. An extended Wagner- Whitin approach is used to determine the replenishment cycle, schedules and lot-sizes.

This paper examines the impact of the regional cash subsidies which were granted in some districts in addition to the national universal stimulus payment in South Korea related to the COVID-19 pandemic. We evaluate the effects of the cash distribution per resident on aggregate credit and debit card sales and sales by industry using the difference-in-difference method. The increment in card spending due to the cash subsidy is about 1.58%p in total, and this effect is concentrated within a single month. The consumption stimulating effect is prominent among (semi)-durable goods that do not require close interactions between customers and sellers. In contrast, the effect is relatively small in the high-contact face-to-face service sectors and restaurants, areas the COVID-19 pandemic hit directly. On the other hand, some service sectors where customers could wear face masks, such as education and fitness, experienced a substantial sales boost due to the cash subsidy.

본 연구는 미국의 자동시장의 시장구조를 분석한 것이다. 자동차 시장의 구조분석는 제품의 특성이 냐내구재라는 점에서 의의가 있다. 그 동안 시장구조분석은 일반포장소비재를 중심으로 분석되어 왔으나 자동차의 시장구조분석는 자동차의 구매주기가 장기간이며, 다음 구매는 많은 소비자가 상위차급으로 이동한다는 점에서 기존의 분석에 사용되었던 상표전환자료를 사용하는데 한계가 있다. 이 때문에 본 연구에서는 구매고려상표군을 중심으로 우사성지수로 사용하여 시장구조분석을 하였다. 자료는 미국의 자동차구매에 관한 이차자료를 활용하였으며, 자료의 특성상 일부차종에 한정하여 사용하였다. 크게 세가지 형태-비용, 비용-형태, 비구조화의 가설적 시장을 비교분석하였으며, 결과적으로 형태-비용 구조가 가장 우수한 것으로 판단되었다.

빠르게 성장하는 국경 간 전자상거래는 전통적인 무역과는 다른 특성을 보인다. 본 연구에서는 그중에서도 제품 유형이나 단가와 같은 품목 특성도 전자상거래 수출에 영향을 줄 수 있는지를 확인하였다. 이를 위해서 한국의 국가별, 품목별 전자상거래 수출 자료와 수출국의 특성 및 품목별 특성을 포함한 패널데이터를 구성하고, 이를 분석하였다. 연구결과 품목별 전자상거래 수출에도 거리의 영향 등이 유효하게 나타났으며, 계약 건별 금액, 내구소비재, 자본재와 같은 품목 특성도 전자상거래 수출에 영향을 미치는 것으로 나타났다. 이러한 연구는 국경 간 전자상거래의 특징에 대한 이해를 고취할 수 있을 것이며, 향후 품목별 데이터를 활용한 연구의 근거로도 활용할 수 있을 것이다.

Market share is one of the most important measures in the valuation of prospering firm. It plays a role of composite indicator for the competitiveness of firm. So, the understanding of the underlying process of market share is inevitable factor for the econometricians and the business engager. Lately, the Korean Economy has been placed in the control of IMF. This shock will cause a lot of influence over the domestic economy. The idea that the information about the past shock-response experience will do us good for dealing with this kind of economic shocks is not new. Among numerous markets, we pay attention to the durable goods market, especially automobile market. The automobile market has large repercussion effect over the domestic economy on the issue of both national employment and technology integration. We divided the Korean automobile market into three segments: small, medium, and large-sized car, while each proportion of these segments has been changing slowly. We propose a Bayesian approach to detect and forecast structural changes in time series of the market shares in the domestic automobile market, especially for level shifts and drift changes, and compare the empirical results with other existing approaches.

본 논문에서는 기업이 아트 콜라보레이션을 진행할 때에 있어서 협력 작가의 국적 선택에 영향을 미치는 요인에 대해 연구하였다. 국내에 보도된 2005-2013년에 발생한 137개의 아트 콜라보레이션 사례를 바탕으로 분석한 결과 국내 기업은 일반적으로 동일한 국적인 국내 작가와의 아트 콜라보레이션을 선호하며, 그 중 내구재 제품에 대한 아트 콜라보레이션은 외국 작가의 비율이 유의하게 높은 것을 발견하였다. 즉 내구재일 경우 제품의 명성이 중요해지기 때문에 협업 과정의 어려움에도 불구하고, 통상적으로 높은 명성을 가질 확률이 높은 외국 작가와의 아트 콜라보레이션을 선호하는 것으로 나타났다.

The purpose of this paper is to prepare a satellite account of the household sector that is reflected in the current national income account by approving the economic activities of unpaid household labor as production activity and estimating its value. The study produced three results. First, as different methods of evaluation can be useful according to different study goals or the contents of related policies, it is unreasonable to present a single result for estimating unpaid household labor. This study, therefore, presented the values of housework based on 5 methods, ranging from 124 to 150 trillion won. Second, to input the added value of household production from the fixed capital (household durable goods), this study adopted the declining balance method used in the Korea National Statistical Office. As a result, the total consumption of fixed capital was estimated at approximately 18.8 trillion won. Third, the total added value of unpaid household labor was estimated to range from 143 to 169 trillion wens. The amount is a production value excluded from the SNA which needs to be formed as a separate household satellite account. The ratio of this total value added was 30-35.4 percents to the 1999 GDP in Korea(477 trillion wens).

The purpose of this study was to examine the factors affecting financial satisfaction of rural housewives. Data for this study were collected from 202 households living in 8 provinces. The results were as follows; 1) The most frequent financial problems experienced from expenditures on clothes(82.1%), lack of expense for social intercourse (61.47), and difficulty in purchasing durable goods(60.1%) in the order. 2) 44.6% of the respondents said they were satisfied with their net worth, and 21.6% of them confessed they had difficulties in debt redemption while 52.5% of them said they felt pressure about monthly payments of installments, which reveals that farm households find it hard to pay back short-term debt. 3) The path analysis was adopted to see the causal relations among the variables influenced the financial satisfaction. The variables of experiences of economic problems, educational background(graduated from middle school), saving, income, and age appeared to be important in the order of effectiveness. Among them, the variables of saying and experiences of economic problems showed a direct effect, and those of age and saving displayed an indirect effect with the experiences of economic problems as the parameter. From this findings, it is suggested that rural extension workers and educators should emphasize the importance of the financial plan in their educational programs.
