On DSGE Models

Journal of Economic Perspectives,
Nr. 3,
2018
Abstract
The outcome of any important macroeconomic policy change is the net effect of forces operating on different parts of the economy. A central challenge facing policymakers is how to assess the relative strength of those forces. Economists have a range of tools that can be used to make such assessments. Dynamic stochastic general equilibrium (DSGE) models are the leading tool for making such assessments in an open and transparent manner. We review the state of mainstream DSGE models before the financial crisis and the Great Recession. We then describe how DSGE models are estimated and evaluated. We address the question of why DSGE modelers—like most other economists and policymakers—failed to predict the financial crisis and the Great Recession, and how DSGE modelers responded to the financial crisis and its aftermath. We discuss how current DSGE models are actually used by policymakers. We then provide a brief response to some criticisms of DSGE models, with special emphasis on criticism by Joseph Stiglitz, and offer some concluding remarks.

Banks Fearing the Drought? Liquidity Hoarding as a Response to Idiosyncratic Interbank Funding Dry-ups
Helge Littke, Matias Ossandon Busch
IWH Discussion Papers,
Nr. 12,
2018
Abstract
Since the global financial crisis, economic literature has highlighted banks’ inclination to bolster up their liquid asset positions once the aggregate interbank funding market experiences a dry-up. To this regard, we show that liquidity hoarding and its detrimental effects on credit can also be triggered by idiosyncratic, i.e. bankspecific, interbank funding shocks with implications for monetary policy. Combining a unique data set of the Brazilian banking sector with a novel identification strategy enables us to overcome previous limitations for studying this phenomenon as a bankspecific event. This strategy further helps us to analyse how disruptions in the bank headquarters’ interbank market can lead to liquidity and lending adjustments at the regional bank branch level. From the perspective of the policy maker, understanding this market-to-market spillover effect is important as local bank branch markets are characterised by market concentration and relationship lending.

Aufschwung in Deutschland weiter kräftig – Anspannungen nehmen zu

Abstract
Der Aufschwung der deutschen Wirtschaft hat an Stärke und Breite gewonnen. In einigen Segmenten, so am Arbeitsmarkt, machen sich inzwischen sogar erste Zeichen einer Anspannung bemerkbar. Neben den Konsumausgaben tragen nun auch die Investitionen und das Auslandsgeschäft zur Expansion bei. Letzteres profitiert davon, dass die Konjunktur im Euroraum deutlich aufwärtsgerichtet ist. Die Expansion dort steht inzwischen auf recht soliden Füßen. Fährt die EZB nun ihre unkonventionellen Maßnahmen schrittweise zurück, sollte dies den Aufschwung im Euroraum nicht gefährden.

The Appropriateness of the Macroeconomic Imbalance Procedure for Central and Eastern European Countries
Martina Kämpfe, Tobias Knedlik
IWH Discussion Papers,
Nr. 16,
2017
Abstract
The experience of Central and Eastern European countries (CEEC) during the global financial crisis and in the resulting European debt crises has been largely different from that of other European countries. This paper looks at the specifics of the CEEC in recent history and focuses in particular on the appropriateness of the Macroeconomic Imbalances Procedure for this group of countries. In doing so, the macroeconomic situation in the CEEC is highlighted and macroeconomic problems faced by these countries are extracted. The findings are compared to the results of the Macroeconomic Imbalances Procedure of the European Commission. It is shown that while the Macroeconomic Imbalances Procedure correctly identifies some of the problems, it understates or overstates other problems. This is due to the specific construction of the broadened surveillance procedure, which largely disregarded the specifics of catching-up economies.

Plant-based Bioeconomy in Central Germany – A Mapping of Actors, Industries and Places
Wilfried Ehrenfeld, Frieder Kropfhäußer
Technology Analysis and Strategic Management,
Nr. 5,
2017
Abstract
The bioeconomy links industrial and agricultural research and production and is expected to provide growth, particularly in rural areas. However, it is still unclear which companies, research institutes and universities make up the bioeconomy. This makes it difficult to evaluate the policy measures that support the bioeconomy. The aim of this article is to provide an inventory of relevant actors in the three Central German states of Saxony, Saxony-Anhalt and Thuringia. First we take an in-depth look at the different sectors, outline the industries involved, note the location and age of the enterprises and examine the distribution of important European industrial activity classification (NACE) codes. Our results underline the fact that established industry classifications are insufficient in identifying the plant-based bioeconomy population. We also question the overly optimistic statements regarding growth potentials in rural areas and employment potentials in general.

Aufschwung in Deutschland festigt sich trotz weltwirtschaftlicher Risiken

2017
Abstract
Die deutsche Wirtschaft befindet sich nun schon im fünften Jahr eines moderaten Aufschwungs, der sich 2018 fortsetzen wird. Auch global expandiert die Wirtschaft kräftig. Die gestiegenen politischen Unsicherheiten dämpfen die Weltwirtschaft derzeit offensichtlich kaum. Der wirtschaftspolitische Kurs der neuen US-Regierung birgt sowohl Chancen als auch Risiken für die Konjunktur in den USA und der Welt. Die Gemeinschaftsdiagnose prognostiziert für 2018 eine Inflationsrate von 1,9% für die fortgeschrittenen Volkswirtschaften und rechnet mit einem Kurswechsel der EZB.

Banking Globalization, Local Lending, and Labor Market Effects: Micro-level Evidence from Brazil
Felix Noth, Matias Ossandon Busch
Abstract
This paper estimates the effect of a foreign funding shock to banks in Brazil after the collapse of Lehman Brothers in September 2008. Our robust results show that bank-specific shocks to Brazilian parent banks negatively affected lending by their individual branches and trigger real economic consequences in Brazilian municipalities: More affected regions face restrictions in aggregated credit and show weaker labor market performance in the aftermath which documents the transmission mechanism of the global financial crisis to local labor markets in emerging countries. The results represent relevant information for regulators concerned with the real effects of cross-border liquidity shocks.

The Risk‐Taking Channel of Monetary Policy in the U.S.: Evidence from Corporate Loan Data
Manthos D. Delis, Iftekhar Hasan, Nikolaos Mylonidis
Journal of Money, Credit and Banking,
Nr. 1,
2017
Abstract
To study the presence of a risk-taking channel in the U.S., we build a comprehensive data set from the syndicated corporate loan market and measure monetary policy using different measures, most notably Taylor (1993) and Romer and Romer (2004) residuals. We identify a negative relation between monetary policy rates and bank risk-taking, especially in the run up to the 2007 financial crisis. However, this effect is purely supply-side driven only when using Taylor residuals and an ex ante measure of bank risk-taking. Our results highlight the sensitivity of the potency of the risk-taking channel to the measures of monetary policy innovations.

Deutsche Wirtschaft gut ausgelastet — Wirtschaftspolitik neu ausrichten

Nr. 10,

Abstract
Die deutsche Wirtschaft befindet sich in einem moderaten Aufschwung. Die Gemeinschaftsdiagnose Herbst 2016 prognostiziert, dass das Bruttoinlandsprodukt 2016 um 1,9%, 2017 um 1,4% und 2018 um 1,6% zulegen dürfte. Dabei gehen von der Weltkonjunktur nur geringe stimulierende Effekte aus, zudem dürften sich in den außerordentlich niedrigen Kapitalmarktzinsen nicht nur die derzeitige Geldpolitik, sondern auch niedrige Wachstumserwartungen widerspiegeln. All dies hemmt die Ausrüstungsinvestitionen. So ist es weiterhin in erster Linie der Konsum, der den Aufschwung trägt.

Foreign Funding Shocks and the Lending Channel: Do Foreign Banks Adjust Differently?
Felix Noth, Matias Ossandon Busch
Finance Research Letters,
November
2016
Abstract
We document for a set of Latin American emerging countries that the different nature of foreign funding accessed by foreign and local banks affected their lending performance after September 2008. We show that lending growth was weaker for shock-affected foreign banks compared to shock-affected local banks. This evidence represents valuable policy information for regulators concerned with the stability and well-functioning of banking sectors.
