Policy Study KOR Evaluating the Effectiveness of Social Policies through a Policy Experiment System

This study proposes that a policy experiment system is introduced to examine the validity of new social polices. Such polices cannot be assessed with the existing Preliminary Feasibility Test and require a small-scale pilot program with an experimental design (typically, randomized controlled trial or RCT) to first be implemented. When the program ends, it is evaluated by the fiscal authorities to decide on whether to scale up the policy.

The policy experiment system presented in this study is applicable to social policies with the following characteristics: i) concrete objective; ii) measurable main outcome and realized in a short period of time and; iii) accessible control group. It is particularly useful when a policy is surrounded by skepticism and/or when budgetary needs are expected to increase in the near future. Accordingly, it can be concluded that the active labor market program is most suitable for the pilot application of the policy experiment system.

Chapter 1 briefly introduces the concept of the policy experiment system while Chapter 2 presents the implementation of the experiment through existing and new labor market programs. Prime examples are the Employment Success Package which was initiated in 2010 and the Youth Job Search Subsidy which is slated for 2019. Chapters 3 and 4 provide practical guides for researchers conducting the policy experiment and summarize the issues of conducting the experiment in the health and welfare field. Finally, Chapter 5 discusses the potential limitations of the system and draws on a conclusion.
