The Effects of Fiscal Policy in an Estimated DSGE Model – The Case of the German Stimulus Packages During the Great Recession
Andrej Drygalla, Oliver Holtemöller, Konstantin Kiesel
Abstract
In this paper, we analyse the effects of the stimulus packages adopted by the German government during the Great Recession. We employ a standard medium-scale dynamic stochastic general equilibrium (DSGE) model extended by non-optimising households and a detailed fiscal sector. In particular, the dynamics of spending and revenue variables are modeled as feedback rules with respect to the cyclical component of output. Based on the estimated rules, fiscal shocks are identified. According to the results, fiscal policy, in particular public consumption, investment, transfers and changes in labour tax rates including social security contributions prevented a sharper and prolonged decline of German output at the beginning of the Great Recession, suggesting a timely response of fiscal policy. The overall effects, however, are small when compared to other domestic and international shocks that contributed to the economic downturn. Our overall findings are not sensitive to the allowance of fiscal foresight.

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.

Joint Economic Forecast—Autumn 2017: Upturn Remains Robust—Amid Mounting Tensions
The German economic upturn has gained both in terms of strength and breadth. In addition to consumer spending, external trade and investments are now also contributing to economic expansion. These are the conclusions drawn by the economic research institutes in their autumn report for the German federal government. Whereas the very high economic momentum in the first half of the current year will slow slightly, expansion of economic output this year and next will exceed production capacity growth. As a result, overall capacity utilization will increase, with economic output exceeding potential output. Gross Domestic Product is likely to grow by 1.9 percent this year and by 2 percent in 2018 (calendar-adjusted: 2.2 and 2.1 percent, respectively).

Networked and protected
During the financial crisis, billions were spent to rescue banks that were according to their governments too big to be allowed to fail. But a study by Michael Koetter from the Halle Institute for Economic Research (IWH) and co-authors shows that besides the size of the banks, the centrality within the global financial network was also pivotal for financial institutions to receive a bail-out.

Ailing banks increase leverage of ailing firms
Euro area countries such as Greece and Spain continue to struggle not only with their banks, but also with highly indebted domestic firms. Michael Koetter from the Halle Institute for Economic Research (IWH) and co-authors show the failure to resolve banks’ financial difficulties also prevents debt reduction of over-leveraged firms – and sometimes even contributes to increasing leverage of the weakest firms.

Higher capital requirements: It’s the firms that end up suffering
61 European banks were scheduled to increase their capital cover by 2012 to provide a sufficient buffer for future crises. As the study by the research group chaired by Reint E. Gropp at the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows, the banks did implement these requirements – not by raising their levels of equity, but by reducing their credit supply. This resulted in lower firm, investment, and sales growth for firms which obtained a larger share of their bank credit from these banks.

Joint Economic Forecast Spring 2017: Upturn in Germany strengthens in spite of global economic risks
The German economy is already in the fifth year of a moderate upturn. According to the Gemeinschaftsdiagnose (GD, joint economic forecast) that was prepared by Germany’s five leading economic research institutes on behalf of the Federal Government, capacity utilization is gradually increasing, and aggregate production capacities are now likely to have slightly exceeded their normal utilisation levels. However, cyclical dynamics remain low compared to earlier periods of recoveries, as consumption expenditures, which do not exhibit strong fluctuations, have been the main driving force so far. In addition, net migration increases potential output, counteracting a stronger capacity tightening. “Gross domestic product (GDP) is expected to expand by 1.5% (1.8% adjusted for calendar effects) and 1.8% in the next year. Unemployment is expected to fall to 6.1% in 2016, to 5.7% in 2017 and 5.4% in 2018”, says Oliver Holtemöller, Head of the Department Macroeconomics and vice president of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association. Inflation is expected to increase markedly over the forecast horizon. After an increase in consumer prices of only 0.5% in 2016, the inflation rate is expected to rise to 1.8% in 2017 and 1.7% in 2018. The public budget surplus will reduce only modestly. Public finances are slightly stimulating economic activity in the current year and are cyclically neutral in the year ahead.

The state as a pioneering customer: How public demand can drive private innovation
Especially in technology-intensive industries, demand from the state can expand private markets and create incentives for privately funded research and development, a new study by the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association shows.
