The Role of Manufacturing-specific Technology in Determining the Composition of Hours Worked in Korea

김배근,김광환 연세대학교 동서문제연구원 2010 Global economic review Vol.39 No.2

This paper investigates the role of manufacturing-specific and neutral technological changes in explaining the dramatic shift in hours worked from the manufacturing toward the service sector. The finding is that manufacturing-specific technological changes are the main contributor to the shift in hours worked while neutral technological changes seem to play only a minor role in explaining it.

시장구조와 노동생산성: 산업별 특성 분석

김배근 ( Bae Geun Kim ) 한국생산성학회 2015 生産性論集 Vol.29 No.1

The relationship between market structure and productivity is explored in this paper using disaggregated industry data for the Korean economy. A structural VAR model is employed to estimate the effects of a rise in market concentration on labor productivity as well as on employment and production. The sectoral analysis in this paper covers ten manufacturing industries as well as five non-manufacturing industries such as electricity, gas and water supply; construction; and three major service sectors. Estimation results for ten manufacturing industries show that higher concentration in product markets leads to an increase in labor productivity in most of manufacturing industries, which supports the Schumpeterian view on this issue. In contrast, it induces a fall in employment. Moreover, output decreases except for a few industries. Thus higher concentration rather has a negative impact on the growth of manufacturing industries. Compared to manufacturing industries, more heterogeneity is found for five non-manufacturing industries. Higher concentration enhances labor productivity except for two industries. For construction, higher concentration reduces labor productivity, which implies that the Arrowian view is valid for this sector. For transport, storage and communications, higher concentration does not have a significant effect on labor productivity. The effect of higher concentration on production also varies substantially across non-manufacturing industries. Output increases in the sectors of electricity, gas and water supply; and finance, insurance, real estate and business services. Output in the construction sector decreases. Output does not change much in the sectors of wholesale and retail trade, restaurants and hotels; and transport, storage and communications. Focused on the output effect, empirical results of this paper suggest that by and large productivity-enhancing measures that lead to higher concentration in product markets may not be so effective in raising the growth potential of each industry.

A Reverse Dipping Pattern Predicts Cardiovascular Mortality In a Clinical Cohort

김배근,김유미,이영주,임영효,신진호 대한의학회 2013 Journal of Korean medical science Vol.28 No.10

An abnormal dipping pattern in ambulatory blood pressure monitoring (ABPM) is a cardiovascular (CV) risk factor. However, its impact on CV mortality has not been investigated sufficiently in clinical practice to be considered a standard parameter. We assessed the association between abnormal dipping patterns and increased CV mortality in a tertiary hospital in Korea. Our retrospective cohort study included 401 patients who underwent ABPM between 1994 and 1996 in Hanyang University Hospital, Seoul, Korea. The patients were classified as risers (<0% drop in systolic BP; n=107), and others included dippers and non-dippers (≥0% drop, n=294). The follow-up period was 120 months. The frequency of CV mortality was 14.0% in risers and 5.8% in others. A Cox regression analysis found a significant association between dipping pattern and CV mortality, after adjusting for age, gender, body mass index, hypertension, diabetes mellitus, smoking and hypercholesterolemia. Risers were at greater risk of CV death than others (RR, 3.02, P=0.022), but there was no difference in event rates between dippers and non-dippers. The reverse dipping pattern may be more frequent in clinical settings than in the population at large, and it is strongly associated with increased risk of CV mortality in Korea.

노동소득분배율 측정 및 결정요인에 관한 연구

김배근 한국은행 2013 經濟分析 Vol.19 No.3

The labor income share is a key indicator that shows the income distribution between capital and labor. This paper presents several measures of the labor income share in the Korean economy that make adjustments for the self-employed and industrial composition effects. It then shows that the degree of imperfect competition in both product and labor markets, such as firms’ market power and labor unions’ bargaining power, can influence the labor income share based on theoretical models. Empirical analyses, however, find that the degree of imperfect competition in product markets is more important in determining the labor income share than that of imperfect competition in labor markets. 노동소득분배율은 자본과 노동간 소득분배 정도를 보여주는 주요한 지표이다. 본 논문에서는 우리나라의 노동소득분배율을 측정해 봄과 아울러 이론적 측면에서 노동소득분배율이 장기적으로 어떠한 요인에 의해 결정되는지를 보인다. 노동소득분배율을 측정할 때 본 연구에서는 우선 자영업 비중이 높은 우리 경제의 특성을 반영하기 위해 자영업자의 소득을 조정하였다. 또한 개별 산업이 차지하는 비중이변함에 따라 경제 전체의 노동소득분배율이 변동할 수 있는데 생산관계에 내재된 자본과 노동 간의 소득분배 결정요인을 파악하기 위해 이와 같은 구성효과도 추가적으로 조정하였다. 이론분석을 통해 보면 노동소득분배율은 생산물시장의 불완전경쟁 정도를 나타내는마크업률 또는 시장집중도, 노동시장의 불완전경쟁 정도를 나타내는 노동조합의 교섭력등에 영향을 받을 수 있다. 그런데 1970년대 이후 기간에 대한 실증분석에서는 이 중 생산물시장의 불완전경쟁 정도가 노동소득분배율에 미치는 영향이 더욱 뚜렷한 것으로 나타났는데 이러한 결과는 산업구조 측면에서 경쟁을 촉진하는 정책이 자본과 노동 간의소득분배를 개선하는 데 상당히 효과적임을 시사한다.

김배근(BK Kim),김재건(JK Kim),한순남(SN Han) 대한산부인과학회 1973 Obstetrics & Gynecology Science Vol.16 No.6

The diagnosis and its problems of 263 cases of ectopic pregnancy and 37 cases in whom the diagnosis was incorrect on admission during 5 years period have been reviewed. 1) The incidence of ectopic pregnancy was 6.8% of live births and recurrent condition in 12.5%. 2) The initial diagnosis was correct in only 86.9%. 3) Postpartum or postabortal endometritis, pelvic operations and other pelvic infections seemed to be the predisposing factors. 4) Culdocentesis is the single most important diagnostic procedure. 5) the failure of obtaining a positive culdocentesis couldn`t rule out the ectopic pregnancy. 6) Of all patients, there was only one death due to acute renal failure. 7) The diagnosis of ectopic pregnancy is depentent upon the clinician`s ability to perform a careful history taking, physical examinations, and to evaluate the results of laboratory findings, culdocentesis and pregnancy tests.

Non-Dipper Pattern is a Determinant of the Inappropriateness of Left Ventricular Mass in Essential Hypertensive Patients

김배근,임영효,이형택,이재웅,김경수,김순길,김정현,임헌길,신진호 대한심장학회 2011 Korean Circulation Journal Vol.41 No.4

Background and Objectives: Inappropriately high left ventricular mass (iLVM) is known to be related to cardiovascular prognosis. A Non-dipper pattern has a greater mean left ventricular (LV) mass than the dipper pattern in hypertensive patients. However, the appropriateness of LV mass in dipper or non-dipper patterns has not been adequately investigated. The aim of this study was to define the relationship between nocturnal dipping and the appropriateness of LV mass. Subjects and Methods: Using the ambulatory blood pressure monitoring (ABPM) database, the data of 361 patients who underwent ABPM and echocardiography was analyzed retrospectively. Appropriateness of LV mass was calculated as observed/predicted ratio of LV mass (OPR) using a Korean-specified equation. Nocturnal dipping was expressed as percent fall in systolic blood pressure (BP) during the night compared to the day. Results: Daytime, nighttime and 24 hours BP in hypertensive patients was 140.4±14.8 mmHg, 143.7±15.2 mmHg and 129.4±20.0 mmHg, respectively. OPR was 106.3±19.9% and nocturnal dipping was 10.2±10.9 mmHg. In a multiple linear regression model, 24 hours systolic BP (β=0.097, p=0.043) and nocturnal dipping (β=-0.098, p=0.046) were independent determinants of OPR as well as age (β=0.130, p=0.025) and body mass index (BMI) (β=0.363, p<0.001). Odds ratio of the non-dipper pattern was 2.134 for iLVM (p=0.021) and 3.694 for obesity (p<0.001; BMI >25 kg/m2). Conclusion: The non-dipper pattern is independently associated with iLVM in hypertensive patients as well as obesity

시장구조와 노동생산성: SVAR 모형을 이용한 동태적 분석

김배근 ( Bae Geun Kim ) 한국생산성학회 2013 生産性論集 Vol.27 No.3

This paper investigates the relationship between market structure and productivity in the Korean economy. Market structure is measured by the markup ratio, that is, the degree to which prices are set over marginal cost. The paper`s novel feature is that it employs SVAR models to identify shocks to market structure and to estimate their effect on labor productivity. Empirical findings of this paper show that labor productivity decreases in the short run after a shock that raises market concentration whereas labor productivity increases in the long run. This suggests that, based on the long-run effect on productivity, the Schumpeterian view on this issue seems valid in the Korean economy.
