Abstract
In this paper we develop an open economy model explaining the joint determination of output, inflation, interest rates, unemployment and the exchange rate in a multi-country framework. Our model -- the Halle Economic Projection Model (HEPM) -- is closely related to studies published by Carabenciov et al. Our main contribution is that we model the Euro area countries separately. In doing so, we consider Germany, France, and Italy which represent together about 70 percent of Euro area GDP. The model combines core equations of the New-Keynesian standard DSGE model with empirically useful ad-hoc equations. We estimate this model using Bayesian techniques and evaluate the forecasting properties. Additionally, we provide an impulse response analysis and a historical shock decomposition.

Introducing Financial Frictions and Unemployment into a Small Open Economy Model
Mathias Trabandt, Lawrence J. Christiano, Karl Walentin
Journal of Economic Dynamics & Control,
No. 12,
2011
Abstract
Which are the main frictions and the driving forces of business cycle dynamics in an open economy? To answer this question we extend the standard new Keynesian model in three dimensions: we incorporate financing frictions for capital, employment frictions for labor and extend the model into a small open economy setting. We estimate the model on Swedish data. Our main results are that (i) a financial shock is pivotal for explaining fluctuations in investment and GDP. (ii) The marginal efficiency of investment shock has negligible importance. (iii) The labor supply shock is unimportant in explaining GDP and no high frequency wage markup shock is needed.

Abstract
The ZIM program (Zentrales Innovationsprogramm Mittelstand) is a technologically open program of the Federal Ministry of Economics and Technology to support small and medium enterprises and Science organizations in their research and innovation activities. It became operative July 1, 2008 and offers three program lines: individual projects, cooperative projects, and networks. In reaction to the global economic crisis the ZIM program was increased for the years 2009 and 2010 – in addition to the regulary scheduled 626 Million – by 900 Million Euro through the Konjunkturpaket II (KP II).
In this study, the analysis of the macroeconomic effects of the ZIM program in Germany has been carried out – first time in the evaluation of federal support programs for research and innovation – by the use of the input output method.

Firm level determinants of innovation: small firms with high potential in East Germany
Jutta Günther, Philipp Marek
Wirtschaft im Wandel,
No. 7,
2011
Abstract
Innovations in the sense of new products and production processes are crucial drivers of the economic development in advanced economies. After a phase of massive technological renewal in East Germany, characterized by much a higher rate of innovators in East than in West Germany, firms in East Germany have to compete with original innovation activities. The paper outlines the innovation activity in East and West Germany and investigates the determinants of product and process innovation within a multivariate analysis using the IAB establishment panel.
The empirical study shows that firms in manufacturing industry in East Germany are quite active in innovation activities in the year 2008. As regards the share of innovative firms there are no substantial differences between East and West Germany. The regression analysis shows that R&D is a significant determinant of innovation in East and West for all types of innovation. In East Germany, further education activities for employees also show a statistically significant impact on innovation. A major difference between East and West could be found for the firm size. In East Germany size has no significant impact on innovation while in West Germany size clearly matters. Different from West Germany, small firms (10 up to 49 employees) in the East have a significantly positive impact on product innovations in the sense of market novelties.

Can Korea Learn from German Unification?
Ulrich Blum
IWH Discussion Papers,
No. 3,
2011
Abstract
We first analyze pre-unification similarities and differences between the two Germanys and the two Koreas in terms of demographic, social, political and economic status. An important issue is the degree of international openness. “Stone-age” type communism of North Korea and the seclusion of the population prevented inner-Korean contacts and contacts with rest of the world. This may create enormous adjustment costs if institutions, especially informal institutions, change. We go on by showing how transition and integration interact in a potential unification process based on the World Bank Revised Minimum Standard Model (RMSM) and on the Salter-Swan-Meade model. In doing so, we relate the macro and external impacts on an open economy to its macro-sectoral structural dynamics. The findings suggest that it is of utmost importance to relate microeconomic policies to the macroeconomic ties and side conditions for both parts of the country. Evidence from Germany suggests that the biggest general error in unification was neglecting these limits, especially limitations to policy instruments. Econometric analysis supports these findings. In the empirical part, we consider unification as an “investment” and track down the (by-and-large immediate to medium-term) costs and the (by-and-large long-term) benefits of retooling a retarded communist economy. We conclude that, from a South-Korean
perspective, the Korean unification will become relatively much more expensive than the German unification and, thus, not only economic, but to a much larger degree political considerations must include the tying of neighboring countries into the convergence process. We finally provide, 62 years after Germany’s division and 20 years after unification, an outlook on the strength of economic inertia in order to show that it may take much more than a generation to compensate the damage inflicted by the communist system.

Fiscal Spending Multiplier Calculations based on Input-Output Tables – with an Application to EU Members
Toralf Pusch, A. Rannberg
Abstract
Fiscal spending multiplier calculations have been revived in the aftermath of the
global financial crisis. Much of the current literature is based on VAR estimation
methods and DSGE models. The aim of this paper is not a further deepening of
this literature but rather to implement a calculation method of multipliers which is
suitable for open economies like EU member states. To this end, Input-Output tables are used as by this means the import intake of domestic demand components can be isolated in order to get an appropriate base for the calculation of the relevant import quotas. The difference of this method is substantial – on average the calculated multipliers are 15% higher than the conventional GDP fiscal spending multiplier for EU members. Multipliers for specific spending categories are comparably high, ranging between 1.4 and 1.8 for many members of the EU. GDP drops due to budget consolidation might therefore be substantial if monetary policy is not able to react in an expansionary manner.

Russia: Overcoming the Effects of Economic Crisis Takes Time
Martina Kämpfe
Wirtschaft im Wandel,
No. 6,
2010
Abstract
The last year's decline of Gross Domestic Product in Russia was harder than in most big economies of the world. The financial crisis has revealed specific circumstances of growth in Russia: The situation deteriorated not only by the downfall of crude oil prices, but especially by the Russian banking sector not being able to satisfy financing demand of the private sector enterprises. So foreign liabilities of enterprises had increased and the dependence of the enterprises on the international financial markets had strengthened. In that way impacts of the global financial crisis affected Russia harder. Although external conditions for the Russian economy improved in the last months due to the rise of world oil prices and global demand for commodities, domestic demand still suffers from small revenues and bad financing conditions for enterprises. Because of its structural weakness it will take Russia longer than other transformation countries to overcome the crisis. Economic growth in the near future will expand much smaller than on last years’ average.

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.
