A new model for time-varying spatial dependencies is introduced. It forms an extension to the popular spatial lag model and can be estimated conveniently by maximum likelihood. The spatial dependence parameter is assumed to follow a generalized autoregressive score (GAS) process. The theoretical...

In this paper we test for (Generalized) AutoRegressive Conditional Heteroskedasticity [(G)ARCH] in daily data on 22 exchange rates and 13 stock market indices using the standard Lagrange Multiplier [LM] test for GARCH and a LM test that is resistant to patches of additive outliers. The data span...

This study assesses the impact of Brexit uncertainty on the UK and also on international financial markets, for the first and the second statistical moments. As financial markets are highly linked in general and several countries apart from the UK might be negatively affected, one may expect...

This study assesses the impact of the uncertainty caused by Brexit, on both the UK and international financial markets, for the first and second statistical moments (i.e. on changes and the standard deviations of the respective variables.) As financial markets are by nature highly interlinked,...

A simple methodology is presented for modeling time variation in volatilities and other higher-order moments using a recursive updating scheme similar to the familiar RiskMetricsTM approach. We update parameters using the score of the forecasting distribution. This allows the parameter dynamics...

We present a simple new methodology to allow for time-variation in volatilities using a recursive updating scheme similar to the familiar RiskMetrics approach. It exploits the link between exponentially weighted moving average and integrated dynamics of score driven time varying parameter...

This paper examines the importance of different economic sentiments, e.g. consumer moods, for the Central and Eastern European countries (CEECs) during the transition process. We first analyze the importance of economic confidence with respect to the CEEC's financial markets. Since the...

This paper explores the extent to which changes to long-term interest rates in major advanced economies have influenced long-term government bond yields in Emerging Asia. To gauge long-term interest spillover effects, the paper uses VAR variance decompositions with high frequency data. Our...
