Recent years have seen a rapid development of model connecting growth and unemployment, but their empirical relevance is not fully known. This paper develops a simple framework for testing a prediction shared by many growth-theoretic models of unemployment, namely, economic fundamentals other...

A congestion toll may have two purposes. First, to reduce congestion the current period. Second, to induce investment which will reduce demand and congestion in later periods. When government cannot credibly commit to future tolle, the optimal toll in the each period may be low, and congestion...
