Should We Use Linearized Models To Calculate Fiscal Multipliers?

Journal of Applied Econometrics,
forthcoming
Abstract
We calculate the magnitude of the government consumption multiplier in linearized and nonlinear solutions of a New Keynesian model at the zero lower bound. Importantly, the model is amended with real rigidities to simultaneously account for the macroeconomic evidence of a low Phillips curve slope and the microeconomic evidence of frequent price changes. We show that the nonlinear solution is associated with a much smaller multiplier than the linearized solution in long-lived liquidity traps, and pin down the key features in the model which account for the di¤erence. Our results caution against the common practice of using linearized models to calculate scal multipliers in long-lived liquidity traps.

Economic activity in the world and in Germany is losing momentum
In the second half of 2018, the upturn of the German economy has stalled. Production of the automotive industry declined because of delays in switching production to WLTP compliant cars. Irrespec-tively of this, the German export business has been weakening since the beginning of the year, since the global economy, burdened by the political uncertainties surrounding trade conflicts, the impending Brexit and the conflict over the Italian budget, was unable to keep up with the high momentum of 2017. “It is to be expected that the less benign external environment will not only dampen exports, but will also impact on companies’ investment and hiring decisions”, says Oliver Holtemöller, head of the Department Macroeconomics and vice president at Halle Institute for Economic Research (IWH). Gross domestic product is expected to increase by 1.5% in 2018 and by 1.4% in 2019, which is roughly equal to the growth rate of economic capacity in Germany.

Central Bank Transparency and the Volatility of Exchange Rates
Stefan Eichler, Helge Littke
Journal of International Money and Finance,
2018
Abstract
We analyze the effect of monetary policy transparency on bilateral exchange rate volatility. We test the theoretical predictions of a stylized model using panel data for 62 currencies from 1998 to 2010. We find strong evidence that an increase in the availability of information about monetary policy objectives decreases exchange rate volatility. Using interaction models, we find that this effect is more pronounced for countries with a lower flexibility of goods prices, a lower level of central bank conservatism, and a higher interest rate sensitivity of money demand.

Banks Fearing the Drought? Liquidity Hoarding as a Response to Idiosyncratic Interbank Funding Dry-ups
Helge Littke, Matias Ossandon Busch
IWH Discussion Papers,
No. 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.

Joint Economic Forecast Spring 2018: Germany’s Economic Experts Raise Forecast Slightly
Berlin, 19 April – Germany’s leading economic experts raised their forecasts for 2018 and 2019 slightly in their Spring Joint Economic Forecast released on Thursday in Berlin. They now expect economic growth of 2.2 percent for this year and 2.0 percent for 2019, versus 2.0 percent and 1.8 percent respectively in their autumn forecast. “The German economy is still booming, but the air is getting thinner as unused capacities are shrinking“, notes Timo Wollmershaeuser, ifo Head of Economic Forecasting. Commenting on the new German government’s economic policy, he adds: “It is precisely when the government’s coffers are full that fiscal policy should reflect the implications of its actions for overall economic stability and the sustainability of public finances. The extension of statutory pension benefits outlined in the coalition agreement runs counter to the idea of sustainability.”

Konjunktur aktuell: Konjunktur weiter stark, aber Risiken nehmen zu
Konjunktur aktuell,
No. 1,
2018
Abstract
Die internationale Konjunktur ist seit Herbst 2016 kräftig, und auch im Jahr 2018 dürfte die Weltwirtschaft deutlich expandieren, nach vorliegender Prognose um 3,3%. Die deutsche Wirtschaft ist derzeit in einer Hochkonjunktur. Allerdings ist zweifelhaft, ob die deutsche Wirtschaft über die Kapazitäten verfügt, um das Tempo des Aufschwungs noch lange durchzuhalten. Das Bruttoinlandsprodukt in Deutschland dürfte im Jahr 2018 mit 2,2% noch einmal recht kräftig und im Jahr 2019 mit 1,6% deutlich moderater expandieren. Der Zuwachs der Produktion in Ostdeutschland dürfte im Jahr 2018 mit 2,0% etwas unter dem in Westdeutschland liegen.

Sovereign Stress, Banking Stress, and the Monetary Transmission Mechanism in the Euro Area
Oliver Holtemöller, Jan-Christopher Scherer
IWH Discussion Papers,
No. 3,
2018
Abstract
In this paper, we investigate to what extent sovereign stress and banking stress have contributed to the increase in the level and in the heterogeneity of non-financial firms’ financing costs in the Euro area during the European debt crisis and how both have affected the monetary transmission mechanism. Employing a large firm-level data set containing two million observations, we are able to identify the effect of government bond yield spreads (sovereign stress) and the share of non-performing loans (banking stress) on firms‘ financing costs in a panel model by assuming that idiosyncratic shocks to individual firms are uncorrelated with country-specific variables. We find that the two sources of stress have increased firms’ financing costs controlling for country and firm-specific factors. Moreover, we estimate both to have significantly impaired the monetary transmission mechanism.

Konjunktur aktuell: Aufschwung in Deutschland und in der Welt
Konjunktur aktuell,
No. 5,
2017
Abstract
Zur Jahreswende ist die deutsche Konjunktur nach wie vor kräftig. Das Bruttoinlandsprodukt dürfte im Jahr 2017 um 2,2% zunehmen, und weil in diesem Jahr deutlich weniger Arbeitstage anfallen als zuvor, beträgt die Zuwachsrate kalenderbereinigt sogar 2,5%. Der Aufschwung ist breit aufgestellt. Schon länger treibt die deutliche Zunahme der Beschäftigung die privaten Einkommen, den Konsum und den Wohnungsbau, der außerdem von den sehr nied-rigen Zinsen Rückenwind erhält. Zudem profitieren die deutschen Exporte zurzeit von der schwungvollen internationalen Konjunktur. Auch weil die Geldpolitik im Euroraum vorerst expansiv bleibt, ist damit zu rechnen, dass sich der Aufschwung im Jahr 2018 fortsetzt; die Produktion dürfte dann erneut um 2,2% zunehmen (auch kalenderbereinigt). Die Verbraucherpreisinflation ist in den Jahren 2017 und 2018 mit 1,7% moderat. Zwar nimmt der binnenwirtschaftliche Preisdruck zu, aber die die Effekte des Energiepreisanstiegs vom Jahr 2017 laufen im Jahr 2018 aus, und die Aufwertung des Euro im Sommer 2017 wirkt preissenkend. Die schon gegenwärtig niedrige Arbeitslosenquote geht im kommenden Jahr weiter zurück. Der Finanzierungssaldo des Staates fällt im Jahr 2018 mit 1,3% in Relation zum Bruttoinlandsprodukt fast so hoch wie im Vorjahr aus, wenn man keine neuen finanzpolitischen Maßnahmen unterstellt. Die ostdeutsche Wirtschaft dürfte in den Jahren 2017 und 2018 mit 2,1% bzw. 2,0% etwas langsamer expandieren als die gesamtdeutsche. Weil das Verarbeitende Gewerbe in Ostdeutschland nicht so exportorientiert ist wie das im Westen, profitiert es auch nicht ganz so stark von der gegenwärtig sehr kräftigen internationalen Konjunktur.

Cyclical upswing in Germany and in the world
At the turn of the year, the cyclical upswing in Germany continues. Gross domestic product is expected to increase by 2.2% in 2017, and because this year has seen significantly fewer working days than before, the rate of change amounts, adjusted for calendar effects, to even 2.5%. “The upswing is broad-based”, says Oliver Holtemöller, head of the Department Macroeconomics and IWH vice president. “For quite a long time now, significant increases in employment have been driving private incomes, consumption and housing construction. The latter was, in addition, stimulated by low interest rates.” Currently, German exports are benefiting from the vivid international economy. Not least since monetary policy in the euro area remains expansionary for the time being, we expect the upturn to continue in 2018 and production to increase again by 2.2%. Consumer price inflation is, with 1.7%, still moderate in both 2017 and 2018. Although domestic price pressures are on the rise, the effects of the energy price increase in 2017 expire in 2018, and the appreciation of the euro in the summer of 2017 will dampen price dynamics.
