This paper uses Granger non–causality tests to analyze if channel competition exists between the companion websites of 93 German newspapers observed between I/1998 and II/2005. It provides econometric evidence for significant negative effects of companion website traffic on the print circulation of national newspapers and for significantly positive effects on local newspapers, at least for the ...

Macro-prudential authorities need to assess medium-term downside risks the real economy, caused by severe financial shocks. Before activating policy measures, they also consider their short-term negative impact. This gives rise a risk management problem, an inter-temporal trade-off between expected growth and risk. Predictive distributions are estimated with structural quantile vector autoregre...

We develop a two-country, dynamic general equilibrium model that links cross-country differences in net foreign asset and consumption dynamics to differences in discount factors and steady-state levels of productivity. We compare the results of the model to those of VARs for the G3 economies. We identify country-specific productivity shocks by assuming that productivity does not respond contemp...

This paper develops a new framework and tools, and reexamines Fama-French regressions. For Fama-French portfolios, we consider a continuous-time factor model with a specific error component structure implied by the underlying asset pricing theory. The model is then analyzed as a continuous-time multivariate regression with a general martingale differential error, allowing for time-varying and s...
