This study set out to analyze empirically the effects of public income security benefits provided at the national level to guarantee the right to live among the disabled on the labor supply of people with disabilities capable of working, thus providing implications for the implementation of a positive income security policy to strike harmony between policy effectiveness and efficiency based on the practical security of right. By using the data of the Korea Welfare Panel Data(2015, the 11th issue) whose fitness for analysis data was high, the investigator analyzed the effects of labor supply according to individual and total public transfer income with the Heckit model. The analysis results show that individual public assistance benefits had statistically significant effects on reduced labor. Social allowance and social insurance benefits had no individual effects of labor supply, but when they were added partially or in total to public assistance(the addition of public assistance and social allowance or the addition of public assistance, social allowance, and social insurance), there were even greater effects on the reduction of labor supply than public assistance alone. It was much bigger among the disabled that belonged to a common household than those to a poor household. As for the overall effects of public transfer benefits on the reduction of labor supply, an increase of annual benefits by 10,000won led to the reduction of labor supply by about 2.71hours with labor supply flexibility at 0.710. The study thus proposed the establishment of a positive in-work income security system based on the custom labor market policy and the taxation policy for each income bracket in parallel under the framework of harmony and connection between the reinforcement of work incentives and the income security system within the public assistance system. It is an attempt to convert transfer benefits from an obstacle to a facilitator in labor supply and promote the riddance and transition from benefits transfer to benefits creation and from a dependent beneficiary to an independent right holder.
