The European Refugee Crisis and the Natural Rate of Output

Applied Economics Letters,
Nr. 16,

Abstract
The European Commission follows a harmonized approach for calculating structural (potential) output for EU member states that takes into account labour as an important ingredient. This article shows how the recent huge migrants’ inflow to Europe affects trend output. Due to the fact that the immigrants immediately increase the working population but effectively do not enter the labour market, we illustrate that the potential output is potentially upward biased without any corrections. Taking Germany as an example, we find that the average medium-term potential growth rate is lower if the migration flow is modelled adequately compared to results based on the unadjusted European Commission procedure.

Taxation and the International Mobility of Inventors

American Economic Review,
Nr. 10,
2016
Abstract
We study the effect of top tax rates on “superstar” inventors’ international mobility since 1977, using panel data on inventors from the US and European Patent Offices. We exploit the differential impact of changes in top tax rates on inventors of different qualities. Superstar inventors' location choices are significantly affected by top tax rates. In our preferred specification, the elasticity to the net-of-tax rate of the number of domestic superstar inventors is around 0.03, while that of foreign superstar inventors is around 1. These elasticities are larger for inventors in multinational companies. An inventor is less sensitive to taxes in a country if his company performs a higher share of its research there.

Geriet die preisliche Wettbewerbsfähigkeit von Euroraum-Ländern nach Gründung der Währungsunion aus dem Gleichgewicht?
Makram El-Shagi, Axel Lindner, Gregor von Schweinitz
Wirtschaft im Wandel,
Nr. 3,
2014
Abstract
Waren die Peripherieländer im Euroraum am Vorabend der Eurokrise nicht mehr wettbewerbsfähig? Oder war die preisliche Wettbewerbsfähigkeit in den Kernländern wie Deutschland ungewöhnlich hoch? Antworten auf diese Fragen sind nicht einfach. Das gängige Maß für die preisliche Wettbewerbsfähigkeit sind die realen effektiven Wechselkurse. Deren Bestimmungsfaktoren waren jedoch kurz vor der Krise selbst möglicherweise nicht im Gleichgewicht und lassen daher kaum Rückschlüsse auf gleichgewichtige Wechselkurse zu. Um dieses Messproblem zu umgehen, wird ein Matching-Ansatz zur Schätzung realer effektiver Wechselkurse verwendet. Dazu wird für jedes Mitgliedsland des Euroraums ein synthetisches Vergleichsland als Kombination mehrerer anderer Länder konstruiert, die den Euro nicht eingeführt haben. Es zeigt sich, dass die Peripherieländer des Euroraums am besten durch eine Mischung von Schwellenländern und entwickelten Volkswirtschaften beschrieben werden, während für ein Matching der Kernländer keine Schwellenländer notwendig sind. Die hier angewendete Methode zeigt, dass die realen effektiven Wechselkurse in den Peripherieländern zwischen Oktober 2007 und September 2008 teilweise deutlich zu hoch waren, während sie in den Kernländern mehr oder weniger nah bei ihrem Gleichgewichtsniveau lagen.

Real Effective Exchange Rate Misalignment in the Euro Area: A Counterfactual Analysis
Makram El-Shagi, Axel Lindner, Gregor von Schweinitz
Abstract
Were real effective exchange rates (REER) of Euro area member countries drastically misaligned at the outbreak of the global financial crisis? The answer is difficult to determine because economic theory gives no simple guideline for determining the equilibrium values of real exchange rates, and the determinants of those values might have been distorted as well. To overcome these limitations, we use synthetic matching to construct a counterfactual economy for each member as a linear combination of a large set of non-Euro area countries. We find that Euro area crisis countries are best described by a mixture of advanced and emerging economies. Comparing the actual REER with those of the counterfactuals gives sensible estimates of the misalignments at the start of the crisis: All peripheral countries were strongly overvalued, while high undervaluation is only observed for Finland.

Global Value Chains During the Great Trade Collapse: A Bullwhip Effect?
Carlo Altomonte, Filippo di Mauro, Gianmarco Ottaviano, Armando Rungi, Vincent Vicard
ECB Working Paper,
Nr. 1412,
2012
Abstract
This paper analyzes the performance of global value chains during the trade collapse. To do so, it exploits a unique transaction-level dataset on French firms containing information on cross-border monthly transactions matched with data on worldwide intrafirm linkages as defined by property rights (multinational business groups, hierarchies of firms). This newly assembled dataset allows us to distinguish firm-level transactions among two alternative organizational modes of global value chains: internalization of activities (intragroup trade/trade among related parties) or establishment of supply contracts (arm's length trade/trade among unrelated parties). After an overall assessment of the role of global value chains during the trade collapse, we document that intra-group trade in intermediates was characterized by a faster drop followed by a faster recovery than arm's length trade. Amplified fluctuations in terms of trade elasticities by value chains have been referred to as the "bullwhip effect" and have been attributed to the adjustment of inventories within supply chains. In this paper we first confirm the existence of such an effect due to trade in intermediates, and we underline the role that different organizational modes can play in driving this adjustment.

A Dynamic Approach to Interest Rate Convergence in Selected Euro-candidate Countries
Hubert Gabrisch, Lucjan T. Orlowski
IWH Discussion Papers,
Nr. 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.

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,
Nr. 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.

FDI and Domestic Investment: An Industry-level View
Claudia M. Buch
CEPR. Discussion Paper No. 6464,
2007
Abstract
Previous empirical work on the link between domestic and foreign investment provides mixed results which partly depend on the level of aggregation of the data. We argue that the aggregated home country implications of foreign direct investment (FDI) cannot be gauged using firm-level data. Aggregated data, in turn, miss channels through which domestic and foreign activities interact. Instead, industry-level data provide useful information on the link between domestic and foreign investment. We theoretically show that the effects of FDI on the domestic capital stock depend on the structure of industries and the relative importance of domestic and multinational firms. Our model allows distinguishing intra-sector competition from inter-sector linkage effects. We test the model using data on German FDI. Using panel cointegration methods, we find evidence for a positive long-run impact of FDI on the domestic capital stock and on the stock of inward FDI. Effects of FDI on the domestic capital stock are driven mainly by intra-sector effects. For inward FDI, inter-sector linkages matter as well.

Where enterprises lead, people follow? Links between migration and FDI in Germany
Claudia M. Buch, J. Kleinert, Farid Toubal
European Economic Review,
Nr. 8,
2006
Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.
