In order to predict the economic impact of the rapid population aging in Korea, we examined the characteristics and prospects of the generational economy using National Transfer accounts data. Korean first posted a life cycle surplus at 27 before turning back into a deficit at 56. As such, the life cycle surplus is seen in the working age group at the main workplace. Five years later, the first-ever surplus and reentry into the deficit were delayed by about two years. These changes in life-cycle deficits can be accounted for in large part by changes in private and public transfers. These are also partly linked to asset reallocation in the private sector.

The aim of this study is to develop a method measuring the deadweight loss of social policy programs and particularly to estimate that of the National Basic Livelihood Security System in Korea. We use the data of the Korea Welfare Panel Study for the estimation, which accumulates a comprehensive survey on low-income persons. Also, we adopt two-stage least-squares (2SLS) including instrumental variables, to resolve the causality problem between an economic activity for income generation (an endogenous variable in our model) and subsidies from the National Basic Livelihood Security System (an exogenous variable in our model); two variables are simultaneously determined. Our empirical results show that the market income per low-income household is reduced on average about 1.35 million won (27.6 percent of public subsidies) due to benefits from the National Basic Livelihood Security System. In addition, we finds that private income transfers cause the largest deadweight loss (13.7 percent of public subsidies), which account for more than a half of the total deadweight loss, and then labor/business income (7.2 percent) and asset income (2.9 percent) are following. This result indicates that public transfers crowd out a great deal of private transfers.

The aim of this study is to suggest a desirable model for cooperative relations between labor and management, analyzing various cases. We derive the characteristics of cooperative industrial relations on the basis of the concepts of "inputs" and "processes’ in the systematic approach. In the aspect of "inputs", we find that in companies with cooperative industrial relations, CEOs consider employees as their colleagues, like family members, and workers are also ready to give their cooperation for the development of their companies. Meanwhile, in the aspect of "processes", most companies with cooperative industrial relations have systems and institutions for removing potential sources of conflict, such as regular meeting/workshops, online communication networks and open management systems, which could boost communication among members within companies and encourage employees actively to participate in management decisions. Our case study shows that cooperative industrial relations ultimately have positive impacts on the business performance of companies that is a common goal of CEOs and employees. In fact, the annual turnover of companies with cooperative industrial relations was four times higher than others and their life-cycle was nearly seven years longer than others. Furthermore, they employed more workers, which contributed to creating more jobs.
