Inflation Expectations: Does the Market Beat Professional Forecasts?

IWH Discussion Papers,
No. 16,
2009
Abstract
The present paper compares expected inflation to (econometric) inflation forecasts
based on a number of forecasting techniques from the literature using a panel of
ten industrialized countries during the period of 1988 to 2007. To capture expected
inflation we develop a recursive filtering algorithm which extracts unexpected inflation from real interest rate data, even in the presence of diverse risks and a potential Mundell-Tobin-effect.
The extracted unexpected inflation is compared to the forecasting errors of ten
econometric forecasts. Beside the standard AR(p) and ARMA(1,1) models, which
are known to perform best on average, we also employ several Phillips curve based approaches, VAR, dynamic factor models and two simple model avering approaches.

Is East Germany Catching Up? A Time Series Perspective
Bernd Aumann, Rolf Scheufele
IWH Discussion Papers,
No. 14,
2009
Abstract
This paper assesses whether the economy of East Germany is catching up with the
West German region in terms of welfare. While the primary measure for convergence and catching up is per capita output, we also look at other macroeconomic indicators such as unemployment rates, wage rates, and production levels in the manufacturingsector. In contrast to existing studies of convergence between regions of reunified Germany, our approach is purely based upon the time series dimension and is thus directly focused on the catching up process in East Germany as a region. Our testing setup includes standard ADF unit root tests as well as unit root tests that endogenously allow for a break in the deterministic component of the process. In our analysis, we find evidence of catching up for East Germany for most of the indicators. However, convergence speed is slow, and thus it can be expected that the catching up process will take further decades until the regional gap is closed.

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.

Are Public Debts of the German Federal States Influencing their Financial Scope?
Sabine Freye
IWH Discussion Papers,
No. 12,
2009
Abstract
Die Bundesländer haben sowohl einnahmen- als aus ausgabenseitig nur eng begrenzte finanzielle Handlungsspielräume. Aus dieser Situation heraus resultierte ein seit Jahr¬zehnten zu beobachtender Anstieg der öffentlichen Schulden. Gegenwärtig steht die Verschuldung der Bundesländer aufgrund der Beschlüsse der Föderalismuskommission II vom März 2009 erneut im Mittelpunkt des Interesses. Die Schuldenbremse beinhaltet die schrittweise erfolgende Rückführung der strukturellen Defizite sowie ein strukturelles Netto-neuverschuldungsverbot der Länder ab dem Jahr 2020. Auf kurze Sicht bedeuten diese Regelungen für die Mehrzahl der Länder eine Einschränkung ihrer finanziellen Hand-lungsspielräume. Der vorliegende Beitrag untersucht, inwieweit diese Spielräume zum gegenwärti¬gen Zeitpunkt in den einzelnen Ländern bestehen. Hierfür werden die Kreditmarkt-schulden je Einwohner sowie die Zins-Steuer- und Zins-Ausgaben-Quoten der Länder betrachtet. Es zeigt sich, dass die fünf Länder, die ab dem Jahr 2010 Konsolidierungs-zahlungen zum Abbau ihrer strukturellen Defizite erhalten werden, im Jahr 2006 im Länder-vergleich zumeist die geringsten finanziellen Handlungsspielräume aus¬wiesen. Die höchsten Belastungen verzeichneten die Stadtstaaten Berlin und Bremen.

Interest Rate Convergence in Euro Candidate Countries: A Dynamic Analysis
Hubert Gabrisch, Lucjan T. Orlowski
Wirtschaft im Wandel,
No. 5,
2009
Abstract
Die vorliegende Studie schlägt einen neuen analytischen Ansatz zur Beurteilung nominaler Konvergenzprozesse in der EU vor. Dieser Ansatz wird auf eines der Maastricht-Kriterien für die Aufnahme eines neuen EU-Mitglieds in die Eurozone angewendet, nämlich die Zinssätze auf langfristige Staatspapiere, gemessen hier als deren Renditen. Das Argument lautet, dass die Dynamik der Renditen Informationen über versteckte Risiken der Zinskonvergenz enthält, die sich durch angemessene ökonometrische Methoden aufdecken lassen. Diese Risiken können selbst dann zutage treten, wenn ein Land das eigentliche Konvergenzkriterium erfüllt hat und dem Euroraum beigetreten ist. Die Risiken der Zinsentwicklung werden von Schwächen der Finanzsysteme der Länder und ihrer makroökonomischen Fundamentaldaten bestimmt. Daraus ist zu schließen, dass eine Betrachtung lediglich der politisch gesetzten Konvergenzkriterien das Risiko von Fehleinschätzungen beinhaltet. Schließlich erlaubt die hier verwendete Methode auch eine Beurteilung der potenziellen Ansteckungseffekte für die Finanz- und Fiskalsysteme durch die gegenwärtige globale Finanzkrise. Die Analyse verdeutlicht, dass bis auf die Slowakei alle untersuchten Länder auf dem Weg zur Euro-Übernahme keine wichtigen Fortschritte hinsichtlich der Reduzierung systemischer Risiken gezeigt haben, sodass nach einer Übernahme des Euro (Slowenien und die Slowakei haben ihn bereits übernommen) eine große Instabilität der Risikoaufschläge zu erwarten ist.

Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
No. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.
