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.

Optimum Currency Areas in Emerging Market Regions: Evidence Based on the Symmetry of Economic Shocks
Stefan Eichler, Alexander Karmann
Open Economies Review,
No. 5,
2011
Abstract
This paper examines which emerging market regions form optimum currency areas (OCAs) by assessing the symmetry of macroeconomic shocks. We extend the output-prices-VAR framework by adding net exports and the real effective exchange rate as endogenous variables. Based on theoretical considerations, we derive which shocks affect these variables in the long run: shocks to labor productivity, foreign trade, labor supply, and money supply. The considered economies of Central and Eastern Europe, the Commonwealth of Independent States, East and Southeast Asia, and South Asia, exhibit large enough shock symmetry to form a currency union; the economies of Africa, Latin America, and the Middle East do not.

Macroeconomic Challenges in the Euro Area and the Acceding Countries
Katja Drechsel
Dissertation, Online-Publikation,
2010
Abstract
The conduct of effective economic policy faces a multiplicity of macroeconomic challenges, which requires a wide scope of theoretical and empirical analyses. With a focus on the European Union, this doctoral dissertation consists of two parts which make empirical and methodological contributions to the literature on forecasting real economic activity and on the analysis of business cycles in a boom-bust framework in the light of the EMU enlargement. In the first part, we tackle the problem of publication lags and analyse the role of the information flow in computing short-term forecasts up to one quarter ahead for the euro area GDP and its main components. A huge dataset of monthly indicators is used to estimate simple bridge equations. The individual forecasts are then pooled, using different weighting schemes. To take into consideration the release calendar of each indicator, six forecasts are compiled successively during the quarter. We find that the sequencing of information determines the weight allocated to each block of indicators, especially when the first month of hard data becomes available. This conclusion extends the findings of the recent literature. Moreover, when combining forecasts, two weighting schemes are found to outperform the equal weighting scheme in almost all cases. In the second part, we focus on the potential accession of the new EU Member States in Central and Eastern Europe to the euro area. In contrast to the discussion of Optimum Currency Areas, we follow a non-standard approach for the discussion on abandonment of national currencies the boom-bust theory. We analyse whether evidence for boom-bust cycles is given and draw conclusions whether these countries should join the EMU in the near future. Using a broad range of data sets and empirical methods we document credit market imperfections, comprising asymmetric financing opportunities across sectors, excess foreign currency liabilities and contract enforceability problems both at macro and micro level. Furthermore, we depart from the standard analysis of comovements of business cycles among countries and rather consider long-run and short-run comovements across sectors. While the results differ across countries, we find evidence for credit market imperfections in Central and Eastern Europe and different sectoral reactions to shocks. This gives favour for the assessment of the potential euro accession using this supplementary, non-standard approach.

Investor Rationality and House Price Bubbles: The Case of Berlin and the German Reunification
Oliver Holtemöller, R. Schulz
German Economic Review,
2010
Abstract
We analyze the behavior of investors in the Berlin rental apartment house market over the years 1980–2004. Using constant-quality multipliers (price–rent ratios), we reject the hypothesis that multipliers in the market were set in a rational manner. Supported by narrative evidence, we conjecture that investors misjudged the economic effects of the German reunification. To examine this, we employ a stylized structural economic model and analyze the effects of shocks on rational multipliers. It seems that investors confused the reunification with a permanent supply side shock to the economy. By basing their investment decisions on this misjudgement, investors behaved irrationally, but in a very uncertain and unprecedented environment.

Real Estate Prices and Bank Stability
Michael Koetter, Tigran Poghosyan
Journal of Banking and Finance,
No. 34,
2010
Abstract
Real estate prices can deviate from their fundamental value due to rigid supply, heterogeneity in quality, and various market imperfections, which have two contrasting effects on bank stability. Higher prices increase the value of collateral and net wealth of borrowers and thus reduce the likelihood of credit defaults. In contrast, persistent deviations from fundamentals may foster the adverse selection of increasingly risky creditors by banks seeking to expand their loan portfolios, which increases bank distress probabilities. We test these hypotheses using unique data on real estate markets and banks in Germany. House price deviations contribute to bank instability, but nominal house price developments do not. This finding corroborates the importance of deviations from the fundamental value of real estate, rather than just price levels or changes alone, when assessing bank stability.

Low Skill but High Volatility?
Claudia M. Buch
CESifo Working Paper No. 2665,
2009
Abstract
Globalization may impose a double-burden on low-skilled workers. On the one hand, the relative supply of low-skilled labor increases. This suppresses wages of low-skilled workers and/or increases their unemployment rates. On the other hand, low-skilled workers typically face more limited access to financial markets than high-skilled workers. This limits their ability to smooth shocks to income intertemporally and to share risks across borders. Using cross-country, industry-level data for the years 1970 - 2004, we document how the volatility of hours worked and of wages of workers at different skill levels has changed over time. We develop a stylized theoretical model that is consistent with the empirical evidence, and we test the predictions of the model. Our results show that greater financial globalization and development increases the volatility of employment, and this effect is strongest for low-skilled workers. A higher share of low-skilled employment has a dampening impact.

Securitization and the Declining Impact of Bank Finance on Loan Supply: Evidence from Mortgage Originations
Elena Loutskina, Philip E. Strahan
Journal of Finance,
No. 2,
2009
Abstract
Low‐cost deposits and increased balance sheet liquidity raise banks' supply of illiquid loans more than loans easily sold or securitized. We exploit the inability of Fannie Mae and Freddie Mac to purchase jumbo mortgages to identify an exogenous change in liquidity. The volume of jumbo mortgage originations relative to nonjumbo originations increases with bank holdings of liquid assets and decreases with bank deposit costs. This result suggests that the increasing depth of the mortgage secondary market fostered by securitization has reduced the effect of lender's financial condition on credit supply.

Crisis Contagion in Central and Eastern Europe
Hubert Gabrisch
Wirtschaft im Wandel,
No. 12,
2008
Abstract
The global financial crisis reached the Central and Eastern European region. Fears of a recession are spreading among investors in Russia and the Ukraine due to the heavy decline of oil and steel prices and provoked a first wave of short-term capital withdrawals. The export sector of all countries in the region is affected by weakening global demand. Finally, the financial sector, which is dominated by international banks in almost all countries, appears as the contagion channel for risk adjustments of mother banks. The combined impact of all these causes and channels lead to a proliferation of restrictions in credit and money supply and an outflow of investment capital. A strong weakening of economic growth is on the way in the region, and a long-lasting recession seems possible in some countries, in first line in the Baltic countries. It becomes a superior task of governments to ease the length and depth of the approaching recession by a strong fiscal stimulus. A continuation of the present policy of fiscal consolidation or of nominal convergence toward a quick adoption of the Euro does not seem very advisable. If governments decided to support domestic demand, measures should be taken to strengthening of a genuinely domestic banking sector in order to maintain credit availability.

Das makroökonometrische Modell des IWH: Eine angebotsseitige Betrachtung
Rolf Scheufele
IWH Discussion Papers,
No. 9,
2008
Abstract
This paper describes the IWH macroeconometric model, a quarterly structural model for the German Economy. It focuses on the specification and estimation on supply-side aspects of the model. This approach guarantees a theoretical derived long-run model equilibrium. It combines short-run forecasting requirements with a long-run theoretical foundation. For some macroeconomic aggregates short- and long-run effects of supply- and demand shocks are illustrated. Additionally, effects of external shocks are investigated through model simulations to illustrate aggregate model characteristics.

Business Cycle Forecast, Summer 2008: Price Hikes and Financial Crisis Cloud Growth Prospects
Wirtschaft im Wandel,
No. 7,
2008
Abstract
In the summer of 2008 the turmoil on financial markets and that on the markets for energy dim the prospects for the world economy. The acceleration of the oil price hike during the first half of the year has led to an increase in expected inflation and to higher interest rates on capital markets, while stock prices are going down. At the same time, the financial crisis is far from over, and banks in the US and in Western Europe continue in their efforts to consolidate their balance sheets. Thus, the expansion of credit supply will be scarcer in the next quarters. All this means that demand will slow in the developed economies during the next quarters. However, the massive fiscal stimulus will help the US economy to stabilize, and the world economy still benefits from the high growth dynamics in the emerging markets economies. All in all, the developed economies will not reach their potential growth rate before the second half of 2009. In Germany, the upswing comes to a temporary halt during summer of this year. Slowing foreign demand and the oil price hike induce firms to postpone investments, and private consumption, the soft spot of the upswing in Germany, is still sluggish due to high inflation rates that impair purchasing power. For the end of 2008, chances are good that growth in Germany accelerates again, because German exporters are still penetrating emerging markets as competitiveness does not diminish. All in all, the German economy will grow by 2.3% in 2008 (mainly due to the very high dynamics at the beginning of the year) and by 1.3% in 2009. A main risk of this forecast is that monetary policy fails in easing the high inflationary pressures. As to fiscal policy, efforts to reach sustainable public finances should not weaken.
