A major criticism against staggered nominal contracts is that they give rise to the so called"persistency puzzle" – although they generate price inertia, they cannot account for thestylised fact of inflation persistence. It is thus commonly asserted that, in the context of thenew Phillips curve...

Motivated by a recent demographic study establishing a link betweenmacroeconomic fluctuations and the mortality index kt in the Lee-Cartermodel, we assess the impact of macroeconomic fluctuations on the solvencyof a life insurance company. Liabilities in our stochastic simulationframework are...

This paper analyzes the evolution of the degree of global cyclicalinterdependence over the period 1960-2005. We categorize the 106 countries in oursample into three groups—industrial countries, emerging markets, and other developingeconomies. Using a dynamic factor model, we then decompose...

Aggregated output in industrialized countries has become less volatile over the pastdecades. Whether this “Great Moderation” can be found in firm level data as wellremains disputed. We study the evolution of firm level output volatility using abalanced panel dataset on German firms that...

Busniess cycle models with sticky prices and endegenous firm entry make novel predictions on the transmission of shocks through the extensive margin of investment. This paper tests some of these predictions using a vector autoregression with model-based sign restrictions. [...]

Using a unique German firm-level data set, this paper is the first to jointlystudy the cyclical properties of the cross-sections of firm-level real value addedand Solow residual innovations, as well as capital and employment adjustment.We find two new business cycle facts: 1) The cross-sectional...

Is time-varying firm-level uncertainty a major cause or amplifier of the businesscycle? This paper investigates this question in the context of a heterogeneousfirmRBC model with persistent firm-level productivity shocks and lumpy capitaladjustment, where cyclical changes in uncertainty...

During the turbulent 1970s and 1980s the Bundesbank established an outstandingreputation in the world of central banking. Germany achieved a high degree of domesticstability and provided safe haven for investors in times of turmoil in the internationalfinancial system. Eventually the Bundesbank...
