We apply the boosting estimation method to investigate to what ex-tent and at what horizons macroeconomic time series have nonlinearpredictability coming from their own history. Our results indicate thatthe U.S. macroeconomic time series have more exploitable nonlinearpredictability than...

The COVID-19 pandemic has led to enormous data movements that strongly affect parameters and forecasts from standard VARs. To address these issues, we propose VAR models with outlier-augmented stochastic volatility (SV) that combine transitory and persistent changes in volatility. The resulting...

VARs are a popular tool for forecasting and structural analysis, but ill-suited to handle occasionally binding constraints, like the effective lower bound on nominal interest rates. We extend the VAR framework by modeling interest rates as censored observations of a latent shadow-rate process,...

Macroeconomic expectations of various economic agents are characterized by substantial cross-sectional heterogeneity. In this paper, we focus on expectations heterogeneity among professional forecasters. We first present stylized facts and discuss theoretical explanations for heterogeneous...

Cogan et al. (2009, 2010) claim that the stimulus package passed by the United States Congress in February 2009 had a multiplier far below one. However, the stimulus ́multiplier strongly depends on the assumed monetary policy response. Based on official statements from the Fed chairman, the...

This paper extends the existing literature on the uniqueness and stability conditions for an equilibrium under inflation-forecast-based (IFB) rules. It shows that, for a variety of New Keynesian sticky-price and sticky-inflation models, these are a function not just of the degree of...

This paper shows that demographic change plays an important role in the formation of a country's net foreign asset position. An ageing population both lowers the demand and increases the supply of capital in an economy. Fewer workers reduce the required capital stock. As a longer life span leads...

While recurring and regular variations of weather conditions are implicitly addressed by standard seasonal adjustment procedures of economic time series, extraordinary weather outcomes are not. We propose a way of measuring aggregate abnormal weather conditions based on available local...

This paper presents long term projections of the German pension system that are based on a general equilibrium model with overlapping generations (OLG). This framework takes into account the two way feedback of both micro and macroeconomic relationships, meaning that households, for example,...

The currently observed demographic change consists of two independent develop-ments that differ in structure and persistence: (1) A slow, monotonic and (presum-ably) permanent ageing effect caused by an increasing life expectancy; (2) a morerapidly changing, non-monotonic and less permanent...
