An Evolutionary Algorithm for the Estimation of Threshold Vector Error Correction Models
Makram El-Shagi
International Economics and Economic Policy,
No. 4,
2011
Abstract
We develop an evolutionary algorithm to estimate Threshold Vector Error Correction models (TVECM) with more than two cointegrated variables. Since disregarding a threshold in cointegration models renders standard approaches to the estimation of the cointegration vectors inefficient, TVECM necessitate a simultaneous estimation of the cointegration vector(s) and the threshold. As far as two cointegrated variables are considered, this is commonly achieved by a grid search. However, grid search quickly becomes computationally unfeasible if more than two variables are cointegrated. Therefore, the likelihood function has to be maximized using heuristic approaches. Depending on the precise problem structure the evolutionary approach developed in the present paper for this purpose saves 90 to 99 per cent of the computation time of a grid search.

Evidence on the effects of inflation on price dispersion under indexation
Juliane Scharff, S. Schreiber
IMK Working Paper, No. 12/2008,
2008
Abstract
Die verzerrenden Auswirkungen von Inflation auf relative Preise sind das Hauptargument für Inflationsstabilisierung in Makromodellen mit Preisrigiditäten. Bei Indexierung von nicht optimierten Preisen implizieren diese Modelle einen nichtlinearen und dynamischen Einfluss von Inflation auf die Preis-Streuung im Querschnitt (relative Preisvariabilität, RPV). Wir schätzen eine verallgemeinerte Form dieser theoretischen Beziehung zwischen Inflation und RPV mit US-Daten. Wir bestätigen den Einfluss von Inflationsschwankungen, jedoch finden wir bisher vernachlässigte Endogenitätsverzerrungen, und unsere IV- und GMM-Schätzungen zeigen, dass die durchschnittliche (“Trend-“) Inflation bei der Indexierung signifikant ist. Die verzögerte Inflationsrate ist weniger wichtig.

Did the Crisis Affect Potential Output?
Makram El-Shagi
Applied Economics Letters,
No. 8,
2011
Abstract
Conventional Phillips-curve models that are used to estimate the output gap detect a substantial decline in potential output due to the present crisis. Using a multivariate state space model, we show that this result does not hold if the long run role of excess liquidity (that we estimate endogeneously) for inflation is taken into account.

The New EU Countries and Euro Adoption
Hubert Gabrisch, Martina Kämpfe
Intereconomics,
No. 3,
2013
Abstract
In the new member states of the EU which have not yet adopted the euro, previous adoption strategies have come under scrutiny. The spillovers and contagion from the global financial crisis revealed a new threat to the countries’ real convergence goal, namely considerable vulnerability to the transmission of financial instability to the real economy. This paper demonstrates the existence of extreme risks for real convergence and argues in favour of a new adoption strategy which does not announce a target date for the currency changeover and which allows for more flexible and countercyclical monetary, fiscal and wage policies.

What Drives Banking Sector Fragility in the Eurozone? Evidence from Stock Market Data
Stefan Eichler, Karol Sobanski
Journal of Common Market Studies,
No. 4,
2012
Abstract
This article explores the determinants of banking sector fragility in the eurozone. For this purpose, a stock-market-based banking sector fragility indicator is calculated for eight member countries from 1999 to 2009 using the Merton model (1974). Using a panel framework, it is found that the macroeconomic environment, the structure of the banking sector and the intensity of banking regulation all have an effect on banking sector fragility in the eurozone.

A Dynamic Approach to Interest Rate Convergence in Selected Euro-candidate Countries
Hubert Gabrisch, Lucjan T. Orlowski
IWH Discussion Papers,
No. 10,
2009
Abstract
We advocate a dynamic approach to monetary convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we empirically test volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001 untill January 22, 2009 sample period. Our results show a varied degree of bond yield co-movements, the most pronounced for the Czech Republic, Slovenia and Poland, and weaker for Hungary and Slovakia. However, since the EU accession, we find some divergence of relative bond yields. We argue that a ‘static’ specification of the Maastricht criterion for long-term bond yields is not fully conducive for advancing stability of financial systems in the euro-candidate countries.
