We focus on a quantitative assessment of rigid labor markets in an environment of stable monetary policy. We ask how wages and labor market shocks feed into the inflation process and derive monetary policy implications. Towards that aim, we structurally model matching frictions and rigid wages in line with an optimizing rationale in a New Keynesian closed economy DSGE model. We estimate the model using Bayesian techniques for German data from the late 1970s to present. Given the pre-euro heterogeneity in wage bargaining we take this as the first-best approximation at hand for modelling monetary policy in the presence of labor market frictions in the current European regime. In our framework, we find that labor market structure is of prime importance for the evolution of the business cycle, and for monetary policy in particular. Yet shocks originating in the labor market itself may contain only limited information for the conduct of stabilization policy.

We construct a utility-based model of fluctuations, with nominal rigidities and unemployment, and draw its implications for the unemployment-inflation trade- off and for the conduct of monetary policy. We proceed in two steps. We first leave nominal rigidities aside. We show that, under a standard utility specification, productivity shocks have no effect on unemployment in the constrained efficient allocation. We then focus on the implications of alternative real wage setting mechanisms for fluctuations in un- employment. We show the role of labor market frictions and real wage rigidities in determining the effects of productivity shocks on unemployment. We then introduce nominal rigidities in the form of staggered price setting by firms. We derive the relation between inflation and unemployment and discuss how it is influenced by the presence of labor market frictions and real wage rigidities. We show the nature of the tradeoff between inflation and unemployment stabilization, and its dependence on labor market characteristics. We draw the implications for optimal monetary policy.

As a fundamental review and critique of activist economic policies, this book is a unique contribution to classical political economy. "Monetary Policy and Macroeconomic Stabilization" is about macroeconomic stabilization policy, with emphasis on the value of a distinct national monetary policy to growth. Ole Bjorn Roste's argument is for public officials to restrain themselves in the pursuit of policy. As the author notes: when you know less, you should do less.The history of modern macroeconomics started in 1936 with the publication of Keynes' "General Theory of Employment, Interest, and Money". The problems of the Great depression of the 1930s paved the way for a change of focus, from the long run to economic fluctuations in the short run, and from nominal to real variables, such as unemployment and aggregate output.Keynes offered clear policy implications in tune with the times. Because economic adjustment was slow, waiting for the economy to recover by itself was irresponsible. Particularly fiscal policy was essential to return to high employment. Monetary policy could affect aggregate demand through Interest rates, but was less important. Roste discusses the role of monetary policy, starting out with the implications of the theory of optimum currency areas (OCAs). This is followed by estimates of the output loss associated with disinflation policy (the sacrifice ratio) for six OECD economies. Further, Roste models the dynamic adjustment to negative, local labor-market shocks, with particular relevance to Scandinavia, in a final section.The idea that governments should pursue stabilizing fiscal or monetary policies with regard to real variables is often taken for granted by the public, if not by economists. Among the reasons for skepticism, is the presence of differing views on how economies really work, that the state of a given economy becomes known only after a time lag, and that economic agents react to policy and expectations of policy. For these reasons, the effects of policy are generally uncertain. This book explains why the role of history is critical to the study of macroeconomics.p>

In this paper, we provide compelling evidence that cyclical factors account for the bulk of the post-2007 decline in the U.S. labor force participation rate. We then proceed to formulate a stylized New Keynesian model in which labor force participation is essentially acyclical during “normal times” (that is, in response to small or transitory shocks) but drops markedly in the wake of a large and persistent aggregate demand shock. Finally, we show that these considerations can have potentially crucial implications for the design of monetary policy, especially under circumstances in which adjustments to the short-term interest rate are constrained by the zero lower bound.
