We propose a novel framework where forward guidance (FG) is endogenously determined. Our model assumes that a monetary authority solves an optimal policy problem under commitment at the zero-lower bound. FG derives from two sources: 1. from commiting to keep interest rates low at the exit of the...

We use a novel procedure to identify fiscal feedback rules for the US: We start by estimating a DSGE model and on that basis compute the Ramsey optimal responses to structural shocks. Then we let the policy maker choose from a general set of rules to match the dynamic behavior of a number of key...

This paper presents a critique of the traditional textbook representation of fiscal policy, and highlights the misleading policy implications perpetuated by this analysis. In particular, the conclusion that fiscal deficits are likely to be associated with higher interest rates is disputed, as is...

Within the context of an agent-based macroeconomic model with dynamic bounded-rational expectations, the most important transmission links between the real sphere of the European economy and the US financial markets crises are simulated: (a) the devaluation of financial assets, (b) global...

We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures of international banks, we can identify banks in Germany with access to U.S. facilities via internal capital markets. Using...

Structural change affects the estimation of economic signals, like the underlying growth rate or the seasonally adjusted series. An important issue, which has attracted a great deal of attention also in the seasonal adjustment literature, is its detection by an expert procedure. The general to...

This paper aims to provide reliable estimates for the COVID-19 contact rate of a Susceptible-Infected-Recovered (SIR) model, From observable data on confirmed, recovered, and deceased cases, a noisy measurement for the contact rate can be constructed, To filter out measurement errors and...

We represent the dynamic relation among variables in vector autoregressive (VAR) models as directed graphs. Based on these graphs, we identify so-called strongly connected components (SCCs). Using this graphical representation, we consider the problem of variable selection. We use the relations...

We analyse the welfare properties of progressive income taxes in a stylized DSGE model of a currency union calibrated to the Eurozone. When the central bank follows a standard Taylor rule and volatility originates solely in productivity shocks, we find that considerable welfare gains can be...

Recent work on financial frictions in New Keynesian models suggest that there is a sizable spread between the risk-less interest rate and the borrowing rate. We analyze the optimal policy mix of monetary and fiscal authorities in a currency union with a country-specific credit spread by...
