In this paper, we develop an aggregation procedure using time-varying weights for constructing the common component of international economic fluctuations. The methodology for deriving time-varying weights is based on some stylized features of the data documented in the paper. The model allows...

This paper provides a new explanation of why inflation is sluggish in response to aggregate demand shocks and why aggregate output changes as result of such shocks. We argue that these phenomena are related to lags between inputs and outputs in the production process, "production lags" for...

This paper considers the problems facing decision makers using econometric models in real time. It identifies the key stages involved and highlights the role of automated systems in reducing the effect of data snooping. It sets out many choices that researchers face in construction of automated...

We propose and estimate a model where unemployment fluctuations result from self-fulfilling changes in expected inflation (sunspot shocks) affecting nominal wage bargaining. Since the estimated parameters fall near the locus of Hopf bifurcations, country-specific expected inflation shocks can...

Nowcasting has been a challenge in the recent economic crisis. We introduce the Toll Index, a new monthly indicator for business cycle forecasting and demonstrate its relevance using German data. The index measures the monthly transportation activity performed by heavy transport vehicles across...

We study fiscal devaluation in a small-open economy with labor market search frictions. Our analysis shows the key role of both dimensions in shaping the optimal tax scheme. By reducing labor market distortions, the tax reform is welfare-improving. Yet, as it makes imports more expensive, fiscal...

Angesichts der gegenwärtigen Finanzmarkt- und Wirtschaftskrise überbieten sich die Anbieter von Prognosen derzeit in immer neuen Schreckenszenarien und pessimistischen Konjunkturvorhersagen. Prognosen beeinflussen Verhalten und Stimmungen und sind deshalb in Krisenzeiten von besonderer...

Wirtschaftspolitische Entscheidungen sollten durch eine sorgfältige Beratung vorbereitet und begleitet werden. Kompetente Beratung seitens der unabhängigen Wissenschaft ist nötig, um einen nachhaltigen Politikansatz zu fördern und tendenziell kurzatmigen Lösungsversuchen entgegen zu wirken....

Despite ubiquitous discussions of robots' potential impact, there is almost no systematic empirical evidence on their economic effects. In this paper we analyze for the first time the economic impact of industrial robots, using new data on a panel of industries in 17 countries from 1993-2007. We...

What are the factors that explain reversals in the implementation of structural reforms? Our main hypothesis is that reversals in different reforms are driven by different factors. This paper uses new reform indicators and presents novel evidence showing that (a) FDI inflows reduce the...
