The effects of shocks on the Austrian unemployment rate - a structural VAR approach

Abstract

Assuming full hysteresis in the Austrian labour market, a simple macroeconomic framework is used to model the effect of four structural shocks, i.e. shocks to productivity, demand, wages and labour supply. By using SVAR analysis, we derive impulse-response functions that show the effects of these shocks on unemployment. What constitutes a distinctive feature of our study is the deliberate use of overidentifying restrictions, allowing for a likelihood ratio test. The objection to SVAR methodology, that it relies on arbitrary assumptions, can thus be overcome, as invalid sets of identifying restrictions are rejected.
