Bayesian Multivariate Time Series Methods for Empirical Macroeconomics

Koop, Gary; Korobilis, Dimitris - Rimini Centre for Economic Analysis (RCEA) - 2009

models have a large number of parameters and, thus, over-parameterization problems may arise. Bayesian methods have become …-varying parameter extensions and show how Bayesian inference proceeds. Apart from the simplest of VARs, Bayesian inference requires the … illustrations. A website provides Matlab code for carrying out Bayesian inference in these models. …

Regime-Switching Cointegration

Jochmann, Markus; Koop, Gary - Rimini Centre for Economic Analysis (RCEA) - 2011

We develop methods for Bayesian inference in vector error correction models which are subject to a variety of switches … Bayesian model averaging r model selection methods can be used to deal with the high-dimensional model space that results. Our …

What Belongs Where? Variable Selection for Zero-Inflated Count Models with an Application to the Demand for Health Care

Jochmann, Markus - Rimini Centre for Economic Analysis (RCEA) - 2009

This paper develops stochastic search variable selection (SSVS) for zero-inflated count models which are commonly used in health economics. This allows for either model averaging or model selection in situations with many potential regressors. The proposed techniques are applied to a data set...

Dynamic probabilities of restrictions in state space models: An application to the Phillips curve

Koop, Gary; Leon-Gonzalez, Roberto; Strachan, Rodney W. - Rimini Centre for Economic Analysis (RCEA) - 2008

Empirical macroeconomists are increasingly using models (e.g. regressions or Vector Autoregressions) where the parameters vary over time. State space methods are frequently used to specify the evolution of parameters in such models. In any application, there are typically restrictions on the...

On the Evolution of Monetary Policy

Koop, Gary; Leon-Gonzalez, Roberto; Strachan, Rodney W. - Rimini Centre for Economic Analysis (RCEA) - 2008

This paper investigates the evolution of monetary policy in the U.S. using a standard set of macroeconomic variables. Many recent papers have addressed the issue of whether the monetary transmission mechanism has changed (e.g. due to the Fed taking a more aggressive stance against ination) or...

Bayesian Inference in the Time Varying Cointegration Model

Koop, Gary; Leon-Gonzalez, Roberto; Strachan, Rodney W. - Rimini Centre for Economic Analysis (RCEA) - 2008

There are both theoretical and empirical reasons for believing that the parameters of macroeconomic models may vary over time. However, work with time-varying parameter models has largely involved Vector autoregressions (VARs), ignoring cointegration. This is despite the fact that cointegration...

Stochastic Search Variable Selection in Vector Error Correction Models with an Application to a Model of the UK Macroeconomy

Jochmann, Markus; Koop, Gary; Leon-Gonzalez, Roberto; … - Rimini Centre for Economic Analysis (RCEA) - 2009

This paper develops methods for Stochastic Search Variable Selection (currently popular with regression and Vector Autoregressive models) for Vector Error Correction models where there are many possible restrictions on the cointegration space. We show how this allows the researcher to begin with...

Does Globalization affect Regional Growth? Evidence for NUTS-2 Regions in EU-27

Polasek, Wolfgang; Sellner, Richard - Rimini Centre for Economic Analysis (RCEA) - 2011

We analyze the influence of newly constructed globalization measures on regional growth for the EU-27 countries between 2001 and 2006. The spatial Chow-Lin procedure, a method constructed by the authors, was used to construct on a NUTS-2 level a complete regional data for exports, imports and...
