Abstract
Der Beitrag untersucht den Zusammenhang von Alterung und Arbeitsmarktmobilität und beantwortet die Frage, ob Mobilität erstens einkommensorientiert erfolgt, ob ältere Beschäftigte zweitens qua Wechsel Lohnzuwächse realisieren können und ob drittens fehlende Lohnanreize den beobachtbaren Mobilitätsrückstand Älterer vollständig erklären können. Die Analyse beschränkt sich auf die betriebliche und berufliche Mobilität von Beschäftigten. Um die Fragen in einem einheitlichen Rahmen beantworten zu können, wird ein Mehrgleichungsmodell geschätzt, das in der empirischen Literatur als switching regression model with endogenous switching bekannt ist. Als Datenbasis fungiert der Regionaldatensatz der IAB-Beschäftigtenstichprobe. Im Ergebnis zeigt sich erstens, dass erwartete Lohnzuwächse die betriebliche und berufliche Mobilität über alle Altersklassen hinweg positiv beeinflussen. Zweitens wird deutlich, dass ältere Beschäftigte sehr viel seltener wechselbedingte Lohnzuwächse realisieren können als jüngere, was einen zentralen Grund für die geringere Wechselneigung Älterer darstellt. Drittens belegt die Analyse jedoch ebenfalls, dass die fehlenden Lohnanreize den Mobilitätsrückstand Älterer nicht vollständig erklären können.

Transmission of Nominal Exchange Rate Changes to Export Prices and Trade Flows and Implications for Exchange Rate Policy
Mathias Hoffmann, Oliver Holtemöller
Scandinavian Journal of Economics,
2010
Abstract
We discuss how the welfare ranking of fixed and flexible exchange rate regimes in a New Open Economy Macroeconomics model depends on the interplay between the degree of exchange rate pass-through and the elasticity of substitution between home and foreign goods. We identify combinations of these two parameters for which flexible and fixed exchange rates are superior with respect to welfare as measured by a representative household's utility level. We estimate the two parameters for six non-EMU European countries (Czech Republic, Hungary, Poland, Slovakia, Sweden, and the UK) using a heterogeneous dynamic panel approach.

Money and Inflation: The Role of Persistent Velocity Movements
Makram El-Shagi, Sebastian Giesen
Abstract
While the long run relation between money and inflation is well established, empirical evidence on the adjustment to the long run equilibrium is very heterogeneous. In the present paper we use a multivariate state space framework, that substantially expands the traditional vector error correction approach, to analyze the short run impact of money on prices. We contribute to the literature in three ways: First, we distinguish changes in velocity of money that are due to institutional developments and thus do not induce inflationary pressure, and changes that reflect transitory movements in money demand. This is achieved with a newly developed multivariate unobserved components decomposition. Second, we analyze whether the high volatility of the transmission from monetary pressure to inflation follows some structure, i.e., if the parameter regime can assumed to be constant. Finally, we use our model to illustrate the consequences of the monetary policy of the Fed that has been employed to mitigate the impact of the financial crisis, simulating different exit strategy scenarios.

Do All Countries Grow Alike?
Claire Economidou, J. W. B. Bos, Michael Koetter, James W. Kolari
Journal of Development Economics,
No. 1,
2010
Abstract
This paper investigates the driving forces of output change in 77 countries during the period 1970–2000. A flexible modeling strategy is adopted that accounts for (i) the inefficient use of resources, and (ii) different production technologies across countries. The proposed model can identify technical, efficiency, and input change for each of three endogenously determined regimes. Membership in these regimes is estimated, rather than determined ex ante. This framework enables explorations into the determinants of output growth and convergence issues in each regime.

Smuggling Illegal versus Legal Goods across the U.S.-Mexico Border: A Structural Equations Model Approach
A. Buehn, Stefan Eichler
Southern Economic Journal,
No. 2,
2009
Abstract
We study the smuggling of illegal and legal goods across the U.S.-Mexico border from 1975 to 2004. Using a Multiple Indicators Multiple Causes (MIMIC) model we test the microeconomic determinants of both smuggling types and reveal their trends. We find that illegal goods smuggling decreased from $116 billion in 1984 to $27 billion in 2004 as a result of improved labor market conditions in Mexico and intensified U.S. border enforcement. Smuggling legal goods is motivated by tax and tariff evasion. While export misinvoicing fluctuated at low levels, import misinvoicing switched from underinvoicing to overinvoicing after Mexico's accession to the GATT and the North American Free Trade Agreement (NAFTA) induced lower tariffs.

Are European Equity Style Indices Efficient? – An Empirical Quest in Three Essays
Marian Berneburg
Schriften des IWH,
No. 28,
2008
Abstract
Many situations in the history of the stock markets indicate that assets are not always efficiently priced. But why does it matter whether the stock market is efficiently priced? Because “well-functioning financial markets are a key factor to high economic growth”. (Mishkin and Eakins, 2006, pp. 3-4) In three essays, it is the aim of the author to shed some more light on the topic of market efficiency, which is far from being resolved. Since European equity markets have increased in importance globally, the author, instead of focusing on US markets, looks at a unified European equity market. By testing for a random walk in equity prices, revisiting Shiller’s claim of excess volatility through the means of a vector error correction model, and modifying the Gordon-Growth-Model, the book concludes that a small degree of inefficiency cannot be ruled out. While usually European equity markets are pricing assets correctly, some periods (e.g. the late 1990s and early 2000s) show clear signs of mispricing; the hypothesis of a world with two states (regime one, a normal efficient state, and regime two, a state in which markets are more momentum driven) presents a possible explanation.

Forecasting Currency Crises: Which Methods signaled the South African Crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
South African Journal of Economics,
2008
Abstract
In this paper we test the ability of three of the most popular methods to forecast South African currency crises with a special emphasis on their out-of-sample performance. We choose the latest crisis of June 2006 to conduct an out-of-sample experiment. The results show that the signals approach was not able to forecast the out-of-sample crisis correctly; the probit approach was able
to predict the crisis but only with models, that were based on raw data. The Markov-regime- switching approach predicts the out-of-sample crisis well. However, the results are not straightforward. In-sample, the probit models performed remarkably well and were also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. The recommendation is to not restrict the forecasting to only one approach.

Softening Competition by Inducing Switching in Credit Markets: A Correction
Jan Bouckaert, Hans Degryse, Jorge Fernández-Ruiz, Miguel García-Cestona
Journal of Industrial Economics,
No. 3,
2008
Abstract
In a recent article in this journal, Bouckaert and Degryse [2004] (denoted B&D) present a model in which banks strategically commit to disclosing borrower information. In this note, we point out an error in B&D and show that, although banks' information disclosure may indeed arise in equilibrium, it only does so if adverse selection is not too harsh.

Three methods of forecasting currency crises: Which made the run in signaling the South African currency crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
IWH Discussion Papers,
No. 17,
2007
Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

Inflation and relative price variability in the euro area: evidence from a panel threshold model
Dieter Nautz, Juliane Scharff
Bundesbank Discussion Paper, No. 14/2006,
2006
Abstract
In recent macroeconomic theory, relative price variability (RPV) generates the
central distortions of inflation. This paper provides first evidence on the empirical
relation between inflation and RPV in the euro area focusing on threshold effects
of inflation. We find that expected inflation significantly increases RPV if inflation
is either very low (below -1.38% p.a.) or very high (above 5.94% p.a.). In the
intermediate regime, however, expected inflation has no distorting effects which
supports price stability as an outcome of optimal monetary policy.
