Combined density nowcasting in an uncertain economic environment
Aastveit, Knut Are; Ravazzolo, Francesco; Dijk, Herman … - 2014
We introduce a Combined Density Nowcasting (CDN) approach to Dynamic Factor Models (DFM) that in a coherent way accounts for time-varying uncertainty of several model and data features in order to provide more accurate and complete density nowcasts. The combination weights are latent random...

Nowcasting in a pandemic using non-parametric mixed frequency VARs
Huber, Florian; Koop, Gary; Onorante, Luca; Pfarrhofer, … - 2021
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...

Macroeconomics, nonlinearities, and the business cycle
Reif, Magnus - 2019
Im Zentrum dieser Dissertation steht das Beschreiben und Erklären von Konjunkturdynamiken. Motiviert durch den außerordentlich starken wirtschaftlichen Einbruch in 2008/2009 betont die Arbeit dabei die Wichtigkeit der Nutzung von nichtlinearen Modellansätzen. Die Dissertation kann als Beitrag...

A non-linear forecast combination procedure for binary outcomes
Lahiri, Kajal; Yang, Liu - 2015
We develop a non-linear forecast combination rule based on copulas that incorporate the dynamic interaction between individual predictors. This approach is optimal in the sense that the resulting combined forecast produces the highest discriminatory power as measured by the receiver operating...

Forecasting with Many Predictors Using Message Passing Algorithms
Korobilis, Dimitris - 2017
Machine learning methods are becoming increasingly popular in economics, due to the increased availability of large datasets. In this paper I evaluate a recently proposed algorithm called Generalized Approximate Message Passing (GAMP), which has been popular in signal processing and compressive...

Bayesian Forecast Combination for VAR Models
Andersson, Michael; Karlsson, Sune - 2008
We consider forecast combination and, indirectly, model selection for VAR models when there is uncertainty about which variables to include in the model in addition to the forecast variables. The key difference from traditional Bayesian variable selection is that we also allow for uncertainty...

On identification of Bayesian DSGE models
Koop, Gary; Pesaran, M. Hashem; Smith, Ron - 2011
In recent years there has been increasing concern about the identification of parameters in dynamic stochastic general equilibrium (DSGE) models. Given the structure of DSGE models it may be difficult to determine whether a parameter is identified. For the researcher using Bayesian methods, a...

The effects of structural shocks on macroeconomic fundamentals under aggressive monetary policy : the case of Turkey
Güngör, Mahmut Sami; Güloğlu, Bülent - In: International journal of business and economic sciences … 12 (2019) 2, pp. 7-21
prior distribution of structural parameters and shock processes are determined according to the literature. Then, we … consistent with theoretical framework of the new Keynesian synthesis. Besides, the historical shock decompositions of endogenous … monetary policy increases the effects of monetary policy shock on inflation while its impact on output gap and interest rate …
