This paper proposes a parsimoniously time varying parameter vector autoregressive model (with exogenous variables, VARX) and studies the properties of the Lasso and adaptive Lasso as estimators of this model. The parameters of the model are assumed to follow parsimonious random walks, where...

We examine the (in)stability of real money demand function and the relevance of money in the contemporary monetary policy framework in Ghana. Both Bai-Perron (2003) structural stability and Quandt-Andrews unknown break tests were applied to ascertain possible structural breaks in Ghana's money...

There is no consensus over the importance of "global forces" on inflation. This study explores the role of structural breaks in the inflation process, and their timing, whether it is common across countries, and the extent to which "global forces" are relevant. Three conclusions stand out....

We assess the efficiency of monetary policy to guide inflation expectations in high and low regimes. Using quantile regression we analyze the persistence of inflation expectations from the Consensus Economics Survey at different quantiles. We find a) empirical evidence that expectations are not...

In order to identify structural shocks that affect economic variables, restrictions need to be imposed on the parameters of structural vector autoregressive (SVAR) models. Economic theory is the primary source of such restrictions. However, only over-identifying restrictions can be tested with...

Malaysia has sustained over four decades of rapid, inclusive growth, reducing its dependence on agriculture and commodity exports to become a more diversified, modern and open economy. GDP per capita is now higher than in a number of OECD economies, while poverty and income inequality have...

Nach den Finanzkrisen der 1990er Jahre haben sich in Asien und Lateinamerika Formen eines monetären Regionalismus (mR) herausgebildet, die das gemeinsame Ziel verfolgen, die eigene Region vor zukünftigen Finanzkrisen zu schützen. Dabei fallen wesentliche Unterschiede im Vorankommen der beiden...

Can fixed exchange rate regimes cause output divergence among member states? We show that such divergence is a long-run equilibrium characteristic of a two-region model with fixed exchange rates, heterogeneous labor markets, and endogenous growth. Under flexible exchange rates, monetary policy...

In addition to its direct effects on the global trading and production structure, the ongoing process of globalisation may have important implications for the interaction of exchange rates and the overall economy. This paper presents evidence regarding possible changes in the role of exchange...
