Abstract
The important role of credit has long been identified as a key factor for economic development (see e.g. Wicksell (1898), Keynes (1931), Fisher (1933) and Minsky (1957, 1964)). Even before the financial crisis most researchers and policy makers agreed that financial frictions play an important role for business cycles and that financial turmoils can result in severe economic downturns (see e.g. Mishkin (1978), Bernanke (1981, 1983), Diamond (1984), Calomiris (1993) and Bernanke and Gertler (1995)). However, in practice researchers and policy makers mostly used simplified models for forecasting and simulation purposes. They often neglected the impact of financial frictions and emphasized other non financial market frictions when analyzing business cycle fluctuations (prominent exceptions include Kiyotaki and Moore (1997), Bernanke, Gertler, and Gilchrist (1999) and Christiano, Motto, and Rostagno (2010)). This has been due to the fact that most economic downturns did not seem to be closely related to financial market failures (see Eichenbaum (2011)). The outbreak of the subprime crises ― which caused panic in financial markets and led to the default of Lehman Brothers in September 2008 ― then led to a reconsideration of such macroeconomic frameworks (see Caballero (2010) and Trichet (2011)). To address the economic debate from a new perspective, it is therefore necessary to integrate the relevant frictions which help to explain what we have experienced during recent years.
In this thesis, I analyze different ways to incorporate relevant frictions and financial variables in macroeconometric models. I discuss the potential consequences for standard statistical inference and macroeconomic policy. I cover three different aspects in this work. Each aspect presents an idea in a self-contained unit. The following paragraphs present more detail on the main topics covered.

Risikoaufschläge für Staatsschulden. Ergebnis von Unsicherheit oder von (akkumulierten) Defiziten?
Toralf Pusch
Zur aktuellen Finanz-, Wirtschafts- und Schuldenkrise. Schriften der Keynes-Gesellschaft, Band 6,
2013
Abstract
Mit Beginn der Finanzkrise 2008 wurde quer durch Europa die antizyklische Fiskalpolitik als Mittel zur Krisenbekämpfung wiederentdeckt. Nach dieser vielleicht wenig überraschenden Renaissance der Fiskalpolitik ist die ökonomische Mehrheitsmeinung inzwischen wieder weitaus skeptischer im Hinblick auf keynesianische Politik. Mittlerweile ist die These sehr verbreitet, es seien die aus dem Ruder gelaufenen Staatsfinanzen in den südlichen Mitgliedsländern (Griechenland, Portugal, Spanien, Italien, ergänzt um das nördlichere Irland), welche die Eurozone in die schärfste Krise seit ihrem Bestehen geführt haben. Als Gradmesser der „Schuldenkrise“ werden dabei im Allgemeinen die steigenden Finanzierungskosten (Risikoaufschläge der Staatsschuldentitel im Vergleich zu deutschen Staatsschulden) in den betroffenen Ländern angeführt. Die in diesem Beitrag vertretene Sichtweise ist hingegen, dass ein wesentlicher Grund für die erhöhten staatlichen Finanzierungskosten in der Zunahme der Unsicherheit an den Finanzmärkten zu sehen ist.

Predicting Financial Crises: The (Statistical) Significance of the Signals Approach
Makram El-Shagi, Tobias Knedlik, Gregor von Schweinitz
Journal of International Money and Finance,
No. 35,
2013
Abstract
The signals approach as an early-warning system has been fairly successful in detecting crises, but it has so far failed to gain popularity in the scientific community because it cannot distinguish between randomly achieved in-sample fit and true predictive power. To overcome this obstacle, we test the null hypothesis of no correlation between indicators and crisis probability in three applications of the signals approach to different crisis types. To that end, we propose bootstraps specifically tailored to the characteristics of the respective datasets. We find (1) that previous applications of the signals approach yield economically meaningful results; (2) that composite indicators aggregating information contained in individual indicators add value to the signals approach; and (3) that indicators which are found to be significant in-sample usually perform similarly well out-of-sample.

Gauging the Effects of Fiscal Stimulus Packages in the Euro Area
Mathias Trabandt, Roland Straub, Günter Coenen
Journal of Economic Dynamics and Control,
No. 2,
2013
Abstract
We seek to quantify the impact on euro area GDP of the European Economic Recovery Plan (EERP) enacted in response to the financial crisis of 2008–2009. To do so, we estimate an extended version of the ECB's New Area-Wide Model with a richly specified fiscal sector. The estimation results point to the existence of important complementarities between private and government consumption and, to a lesser extent, between private and public capital. We first examine the implied present-value multipliers for seven distinct fiscal instruments and show that the estimated complementarities result in fiscal multipliers larger than one for government consumption and investment. We highlight the importance of monetary accommodation for these findings. We then show that the EERP, if implemented as initially enacted, had a sizeable, although short-lived impact on euro area GDP. Since the EERP comprised both revenue and expenditure-based fiscal stimulus measures, the total multiplier is below unity.

Vertical Grants and Local Public Efficiency
Ivo Bischoff, Peter Bönisch, Peter Haug, Annette Illy
Abstract
This paper analyses the impact of vertical grants on local public sector efficiency. First, we develop a theoretical model in which the bureaucrat sets the tax price while voters choose the quantity of public services. In this model, grants reduce efficiency if voters do not misinterpret the amount of vertical grants the local bureaucrats receive. If voters suffer from fiscal illusion, i.e. overestimate the amount of grants, our model yields an ambiguous effect of grants on efficiency. Second, we use the model to launch a note of caution concerning the inference that can be drawn from the existing cross-sectional studies in this field: Taking into account vertical financial equalization systems that reduce differences in fiscal capacity, empirical studies based on cross-sectional data may yield a positive relationship between grants and efficiency even when the underlying causal effect is negative. Third, we perform an empirical analysis for the German state of Saxony-Anhalt, which has implemented such a fiscal equalization system. We find a positive relationship between grants and efficiency. Our analysis shows that a careful reassessment of existing empirical evidence with regard to this issue seems necessary.

Währung ohne Souverän: Zur Ursache und Überwindung der Euro-Krise
Hubert Gabrisch
Leviathan - Berliner Zeitschrift für Sozialwissenschaft,
No. 1,
2013
Abstract
Ich argumentiere, dass eine Währung einen Souverän braucht, um Stabilität auf den Finanzmärkten und in der Realwirtschaft zu sichern. Andernfalls würde eine Währungsunion über kurz oder lang zerfallen. Insofern ist die aktuelle Krise des Euro-Raums auf das Fehlen eines Souveräns zurückzuführen. Die Theorie des optimalen Währungsraums bringt keine Erkenntnisse zur Überwindung der Krise, weil sie die Separierung von Geld und Staat als Grundlage hat. Auch deshalb liefert sie eher eine Begründung für Reformen wie den Fiskalpakt, dem zufolge fiskalische Operationen von der Einschätzung der Finanzmärkte abhängen sollen. Ich zeige, wie der Fiskalpakt im Gegenteil zu einer tiefen Rezession und zu einer dauerhaften Kluft zwischen Gläubiger- und Schuldnerländern führen wird. Notwendig ist vielmehr eine Transformation der Währungsunion in einen souveränen Währungsraum, in dem eine effektive Koordination von Geld- und Fiskalpolitik zwischen einer EU-Finanzbehörde und der Zentralbank im Sinne einer funktionalen Fiskalpolitik möglich wird.

The Role of Uncertainty in the Euro Crisis - A Reconsideration of Liquidity Preference Theory
Toralf Pusch
Journal of Post Keynesian Economics,
2013
Abstract
With the world financial crisis came the rediscovery of the active role fiscal policy could play in remedying the situation. More recently, the Euro Crisis, with its mounting funding costs facing governments of a number of Southern EU member states and Ireland, has called this strategy into question. Opposing this view, the main point of this contribution is to elaborate on the link between rising sovereign risk premia in the Eurozone and a major feature of the financial crisis - elevated uncertainty after the Lehman collapse. Theoretically, this link is developed with reference to Keynes' liquidity preference theory. The high explanatory power of rising uncertainty in financial markets and the detrimental effects of fiscal austerity on the evolution of sovereign risk spreads are demonstrated empirically by means of panel regressions and supplementary correlation analyses.

Qual VAR Revisited: Good Forecast, Bad Story
Makram El-Shagi, Gregor von Schweinitz
Abstract
Due to the recent financial crisis, the interest in econometric models that allow to incorporate binary variables (such as the occurrence of a crisis) experienced a huge surge. This paper evaluates the performance of the Qual VAR, i.e. a VAR model including a latent variable that governs the behavior of an observable binary variable. While we find that the Qual VAR performs reasonably well in forecasting (outperforming a probit benchmark), there are substantial identification problems. Therefore, when the economic interpretation of the dynamic behavior of the latent variable and the chain of causality matter, the Qual VAR is inadvisable.

Initial Evidence from a New Database on Capital Market Restrictions
Makram El-Shagi
Panoeconomicus,
No. 3,
2012
Abstract
One of the key obstacles to the empirical analysis of capital controls has been the unavailability of a detailed set of indicators for controls that cover a broad set of countries over a range of years. In this paper, we propose a new set of indicators derived from the Annual Reports on Exchange Arrangements and Export Restrictions. Contrary to most earlier attempts to construct control indicators from this source, our set of indices allows one to analyze the control intensity separately for inflow, outflow and repatriation controls. An additional set of indicators features information on the institutional design of controls. At first glance, the data show that the financial crisis caused a surge in capital market restrictions, most notably concerning the derivatives market. This reflex, which is not justified by the scarce empirical evidence on the success of controls, shows the importance of having a valid measure to allow an econometrically sound policy evaluation in this field. The data are available from the author upon request.
