1989~91년과 2004~7년에 이루어진 법정근로시간 단축이 실근로시간과 고용, 실질임금에 미친 영향을 분석했다. 통상적인 회귀분석과 벡터오차수정 모형을 병행해서 추정한 결과 확인된 사실은 다음과 같다. 첫째, 법정근로시간 단축으로 실근로시간과 월근로일수가 감소했다. 법정근로시간을 10% 단축할 때 실근로시간은 8.0% 감소하고 월근로일수는 3.0% 감소했다. 둘째, 법정근로시간 단축에 따른 실근로시간 단축은 고용증가로 이어졌다. 근로시간을 10% 단축할 때 단기적으로는 고용증가 폭이 미미하지만, 장기적으로 취업자는 8.5%, 노동자는 13.1% 증가했다. 셋째, 실근로시간 단축으로 시간당임금은 증가했다. 즉 실근로시간이 10% 단축될 때 시간당임금은 장기적으로 13.3% 증가했다. 그러나 월임금총액은 유의미한 영향을 받지 않았다.

We use a set of Korea panel data to estimate effects of legal working hours reduction on actual hours worked and employment effects, through panel econometrics methods. Taking account of sequential decrease in legal hours worked since 2004, we estimate the relationship between legal and actual working hours by size of industries. It is found that one hour reduction of legal hours per week caused 0.44 to 1.05 actual hours worked on average per week, depending on different industrial sizes. Also, estimated employment effects were not unanimously determined, rather they turn out to be clearly size-dependent, which provide different results from exiting literature. Our analysis proposed in this work can be restrictive as, for instance, there is significant lack of data for foreign workers, particularly in the small-sized industries. Subsequent empirical analysis is expected.

In case of reducing working time, it is difficult that the construction industry is analyzed far-reaching effects caused by a reduction of working time, by approaching with just the total amount of work. Because it has the properties such as the singularity, the outdoor using, a sense of the season unlike other industries. In order to analyze the effect of a reduction of working time on the construction industry, the example of a reduction of working time in domestic other industries related with it was analyzed intensively first. And an example in Japan, which is similar to our existing related laws and industrial structure among foreign construction industries was analyzed, and a relation with the domestic construction industries and an issue were drown a conclusion. This was applied to a field worker and a related main group participating in a real production. And it showed the prediction model for a working pattern and a dealing plan to prepare in a construction site by predicting a working pattern in the management side of a construction site annually.

The question about whether a shorter workweek may increase employment has been a serious issue and been furiously debated among collective bargainers. The advocators recommend publicly that a reduction in standard working hours will provide benefits to the unemployed through the provision of new jobs, and also can improve the quality of life workers. The opponents argue that a shorter workweek will increase labor costs and induce firms to reduce their production levels, and consequently cut back their demand for labor. Although the debate is still continuing, considerable has been made toward achieving the goal workweek reduction. The analytical framework of this paper is a Putty-clay-model, in which the short-and long-term impacts of changes in working time on the employment associated with the interrelations of wages, prices, hourly labour productivity, the firm's labor demand, business cycle and economic growth etc. must be analyzed.

This study analyzes effects of the proposed reduction of legal working hours in Korea in which base wage is unchanged with working hours reduction. The theoretical analysis shows that a reduction of legal working hours would result in less than equal size reduction of actual working hours, and increase in wages. On the other hand, the effects on employment is ambiguous depending on the substitution effect and scale effect. An empirical analysis based on macro-economic model simulation supports the theoretical conjecture. It has been found that with the reduction of legal working hours, real wages and consumption increase while actual working hours decreases about half of the legal hours reduction. In addition, the immediate and outright imposition of legal hours reduction on all sectors of the economy is found to create a cost push inflation and reduce GDP, investment, and employment. This negative effects are lessened as the reduction of legal hours is gradually made and/or some measures to absorb the cost shock such as abolition of paid monthly leave are employed together.

This paper investigates the effects of hours reduction on growth, investment, and consumption as well as employment. We adopt the basic framework of the indivisibility of labor developed by Hansen (1985) and Rogerson (1988) and extend it by allowing heterogeneity of workers in productive efficiency. On the basis of monthly panel data constructed from Economically Active Population Surveys and Household Income and Expenditure Surveys, we estimate the value of productive efficiency parameter of newly hired workers relative to existing workers by considering differences between the two groups in unobservable as well as observable worker characteristics. Numerical simulation of steady states demonstrates that reduction of statutory weekly hours from 44 to 40 leads to a rise in employees by 4.9 percent. However, GNP, investment, and consumption are all reduced by 2.03 percent, which is attributed to reduction in the amount of effective labor input, which in turn comes from reduction of actual average hours and productivity differences between exiting and newly hired workers.

This study is a study on the change of life and leisure satisfaction caused by the reduction of working hours of office workers, summarizing the results of the analysis as follows: First, the change in the working hours of office workers was found to be men (42.4 percent), but women (54.7 percent) had a high increase in personal satisfaction, monthly income of 2 to 3 million won 96.1 percent, and personal satisfaction increased in small and medium-sized cities and towns. Second, leisure satisfaction due to shorter working hours was somewhat high in monthly income of 3 million won to 4 million won (43.6%) and more than 6 million won (39.1%), but there was no change in leisure satisfaction by gender, age, academic background, number of family members, marital status, worker status and region. The revitalization of leisure is a very important task in personal life, but it is meaningful in that it provided implications for socializing leisure as leisure satisfaction is positively spreading in life changes.

After the new standards for labor hours has been released, various problems come up in construction field, such as income reduction of employees, extension of construction period and increased construction cost. Although it is expected that the impact of the new standard on the construction industry is more worse than other industries form the view of productivity, not much works have been done to identify those impacts. Thus, this research proposes the standard construction processes, excavation cycle, and unit construction period for NATM tunnel project based on 'Construction Standard Production Rates.'The study also investigated the impact of reduced labor hours on the management of work crews, construction periods and costs of tunnel projects. The results showed that under the 52 labor hour standard, the construction periods for the excavation work and whole project was increased by 20% and 8.9%, respectively, but the construction costs for the excavation work and whole project was decreased by 1.4% and 0.6%, respectively.

This paper estimates the impacts of introducing the 40 hour work week standard in South Korea on actual working hours, wages and employment. We exploit variation in timing of implementing the 40 hour work week standard across industries and establishment size and estimate the causal effects by a triple difference model. Our results show that the 40 hour work week standard decreased actual working hours by about 43 minutes while it increased hourly wage rate by 6.6%. The probability of new hires decreased by about 2.3% points.

Labor contracts appear in form as an exchange relationship between labor products and wages, but since they transcend the level of simple barter, they can be economically identified as "trading" and can be identified as "rental." From a legal point of view, a legal device that legally supports and imposes binding force on commodity exchange relations is a contract. Such a labor contract led to a relationship in which wages were received and a certain amount of time was placed under the direction and supervision of the employer as a counter benefit to the receipt of wages. Since working hours are subordinate hours with one's labor under the disposition authority of the employer, long hours of work can be done for the health and safety of workers and furthermore, it can be an act that violates the value to enjoy as a human being. The reduction of working hours needs to be shortened in terms of productivity and enjoyment of workers' culture so that they can expand and reproduce, but users' corporate management labor and production activities should also be compatible compared to those pursued by capitalist countries. Working hours can be seen as individual time and time in society as a whole, and long hours of work at the individual level are reduced, which is undesirable at the individual level, but an increase in products due to an increase in production time at the social level can help social development. It is necessary to consider working hours in terms of finding the balance between these individual and social levels. If the regulation method of working hours was to regulate the total amount of working hours, flexibility and elasticity of working hours are a qualitative regulation method that allows companies to flexibly allocate and organize working hours within a certain range of up to 52 hours per week. Accordingly, it is necessary to shorten working hours, but expand and implement the flexible working hours system according to the situation of the company. To this end, it is necessary to flexibly operate the flexible working hours system, which is currently limited to six months, handle the selective working hours by agreement between employers and workers, and expand the target work of discretionary working hours according to the development of information and communication technology and new types based on the 4th industrial revolution.
