We point out that the simple slice sampler generates chains that are correlation-free when the target distribution is centrally symmetric. This property explains several results in the literature about the relative performance of the simple and product slice samplers. We exploit it to improve...

Using variance decompositions in vector auto-regressions (VARs) we model a high-dimensional network of European CDS spreads to assess the transmission of credit risk to the non-financial corporate sector. Our findings suggest a sectoral clustering in the CDS network, where financial institutions...

This paper develops Bayesian econometric methods for posterior inference in non-parametric mixed frequency VARs using additive regression trees. We argue that regression tree models are ideally suited for macroeconomic nowcasting in the face of extreme observations, for instance those produced...

This paper proposes a piecewise-linear Kalman filter (PKF) to estimate DSGE models with occasionally binding constraints. This method expands the set of models suitable for nonlinear estimation. It straightforwardly handles missing data, non-singularity (more shocks than observed time series),...

The effect of a firm's size is analysed in relation with the probability of applying for a patent. We worked on the identification of a firm's minimum size, a threshold needed to formally protect an innovation by legal means. Below this minimum size the costs associated with protection are so...

The present paper develops Adaptive Trees, a new machine learning approach specifically designed for economic forecasting. Economic forecasting is made difficult by economic complexity, which implies non-linearities (multiple interactions and discontinuities) and unknown structural changes (the...

I examine the relevance of contagion in explaining financial distress in the US banking system by identifying the component of bank level probabilities that is due to contagion. Identification is achieved after controlling for macrofinancial and bank specific shocks that have similar...

Turkey’s current account deficit widened to almost 10% of GDP in 2011 and has been narrowing only gradually since. An important question is to what extent Turkey’s current account deficit is excessive. To explore this issue, one needs to establish benchmarks. In this paper current account...

We study the impact of debt maturity management in an economy where monetary policy is 'passive' and subservient to fiscal policy. We setup a tractable model, to characterize analytically the dynamics of in ation, as well as other macroeconomic variables, showing their dependence on the monetary...

The COVID-19 pandemic led to a sharp contraction of economic activity in the euro area (and worldwide). Its anatomy differs strongly from other crises in recent history. We analyse the short-term economic effects of the COVID-19 shock through the lens of an estimated DSGE model. We augment the...
