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.

Global Food Prices and Monetary Policy in an Emerging Market Economy: The Case of India
Oliver Holtemöller, Sushanta Mallick
Journal of Asian Economics,
2016
Abstract
This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that a big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks.

Impulse Response Analysis in a Misspecified DSGE Model: A Comparison of Full and Limited Information Techniques
Sebastian Giesen, Rolf Scheufele
Applied Economics Letters,
No. 3,
2016
Abstract
In this article, we examine the effect of estimation biases – introduced by model misspecification – on the impulse responses analysis for dynamic stochastic general equilibrium (DSGE) models. Thereby, we use full and limited information estimators to estimate a misspecified DSGE model and calculate impulse response functions (IRFs) based on the estimated structural parameters. It turns out that IRFs based on full information techniques can be unreliable under misspecification.

Time-varying Volatility, Financial Intermediation and Monetary Policy
S. Eickmeier, N. Metiu, Esteban Prieto
IWH Discussion Papers,
No. 19,
2016
Abstract
We document that expansionary monetary policy shocks are less effective at stimulating output and investment in periods of high volatility compared to periods of low volatility, using a regime-switching vector autoregression. Exogenous policy changes are identified by adapting an external instruments approach to the non-linear model. The lower effectiveness of monetary policy can be linked to weaker responses of credit costs, suggesting a financial accelerator mechanism that is weaker in high volatility periods. To rationalize our robust empirical results, we use a macroeconomic model in which financial intermediaries endogenously choose their capital structure. In the model, the leverage choice of banks depends on the volatility of aggregate shocks. In low volatility periods, financial intermediaries lever up, which makes their balance sheets more sensitive to aggregate shocks and the financial accelerator more effective. On the contrary, in high volatility periods, banks decrease leverage, which renders the financial accelerator less effective; this in turn decreases the ability of monetary policy to improve funding conditions and credit supply, and thereby to stimulate the economy. Hence, we provide a novel explanation for the non-linear effects of monetary stimuli observed in the data, linking the effectiveness of monetary policy to the procyclicality of leverage.

Upturn Remains Moderate — Economic Policy Lacks Growth Orientation

No. 5,
2016
Abstract
Die deutsche Wirtschaft befindet sich in einem moderaten Aufschwung. Zu diesem Ergebnis kommt die Mitte April veröffentlichte Gemeinschaftsdiagnose der Wirtschaftsforschungsinstitute. Das Bruttoinlandsprodukt dürfte demnach in diesem Jahr um 1,6% und im kommenden Jahr um 1,5% zulegen. Getragen wird der Aufschwung vom privaten Konsum, der vom anhaltenden Beschäftigungsaufbau, den spürbaren Steigerungen der Lohn- und Transfereinkommen und den Kaufkraftgewinnen infolge der gesunkenen Energiepreise profitiert.

Nested Models and Model Uncertainty
Alexander Kriwoluzky, Christian A. Stoltenberg
Scandinavian Journal of Economics,
No. 2,
2016
Abstract
Uncertainty about the appropriate choice among nested models is a concern for optimal policy when policy prescriptions from those models differ. The standard procedure is to specify a prior over the parameter space, ignoring the special status of submodels (e.g., those resulting from zero restrictions). Following Sims (2008, Journal of Economic Dynamics and Control 32, 2460–2475), we treat nested submodels as probability models, and we formalize a procedure that ensures that submodels are not discarded too easily and do matter for optimal policy. For the United States, we find that optimal policy based on our procedure leads to substantial welfare gains compared to the standard procedure.

Asymmetric Investment Responses to Firm-specific Uncertainty
Julian Berner, Manuel Buchholz, Lena Tonzer
Abstract
This paper analyzes how firm-specific uncertainty affects firms’ propensity to invest. We measure firm-specific uncertainty as firms’ absolute forecast errors derived from survey data of German manufacturing firms over 2007–2011. In line with the literature, our empirical findings reveal a negative impact of firm-specific uncertainty on investment. However, further results show that the investment response is asymmetric, depending on the size and direction of the forecast error. The investment propensity declines significantly if the realized situation is worse than expected. However, firms do not adjust their investment if the realized situation is better than expected, which suggests that the uncertainty effect counteracts the positive effect due to unexpectedly favorable business conditions. This can be one explanation behind the phenomenon of slow recovery in the aftermath of financial crises. Additional results show that the forecast error is highly concurrent with an ex-ante measure of firm-specific uncertainty we obtain from the survey data. Furthermore, the effect of firm-specific uncertainty is enforced for firms that face a tighter financing situation.

International Banking and Liquidity Risk Transmission: Evidence from Canada
James Chapman, H. Evren Damar
IMF Economic Review,
No. 3,
2015
Abstract
This paper investigates how liquidity conditions in Canada may affect domestic and/or foreign lending of globally active Canadian banks, and whether this transmission is influenced by individual bank characteristics. It finds that Canadian banks expanded their foreign lending during the recent financial crisis, often through acquisitions of foreign banks. It also finds evidence that internal capital markets play a role in the lending activities of globally active Canadian banks during times of heightened liquidity risk.

Joint Forecast: Migration of Refugees will Challenge Economic Policy

Wirtschaftsdienst,
No. 10,
2015
Abstract
Die an der Gemeinschaftsdiagnose teilnehmenden Institute prognostizieren in ihrer Herbstdiagnose, dass die deutsche Wirtschaft in diesem und im kommenden Jahr um jeweils 1,8% expandieren wird. Damit setzt sich zwar der Aufschwung fort, er dürfte aber moderat bleiben. Bremsend wirkt die Abschwächung des Wachstums in den Schwellenländern. Im weiteren Prognosezeitraum wird der Aufschwung vor allem von den privaten Konsumausgaben getragen. Zwar wurden auch die Sachinvestitionen des Staates ausgeweitet. Für moderne Volkswirtschaften sind Investitionen in Köpfe aber wichtiger als Investitionen in Beton. Im Bereich der Bildung gilt es, Wachstumspotenziale zu heben.
