Growth and non-regular employment

The share of non-regular employment has been increasing in many developed countries during the past two decades. The objective of this paper is to study a cause of the upward trend in non-regular employment by focusing on productivity growth. Data from Japan shows that the slowdown in productivity growth increases both unemployment and the proportion of non-regular workers to total employed workers. In order to study the impact of long-run productivity growth on unemployment and non-regular employment, I develop a search and matching model with disembodied technological progress and two types of jobs, regular and non-regular jobs. The numerical analysis demonstrates that the slowdown in productivity growth increases the share of non-regular employment and the unemployment rate, which is consistent with empirical facts.
