Expectation Formation, Financial Frictions, and Forecasting Performance of Dynamic Stochastic General Equilibrium Models

Oliver Holtemöller Christoph Schult

in: IWH Discussion Papers, No. 15, 2018

Abstract

In this paper, we document the forecasting performance of estimated basic dynamic stochastic general equilibrium (DSGE) models and compare this to extended versions which consider alternative expectation formation assumptions and financial frictions. We also show how standard model features, such as price and wage rigidities, contribute to forecasting performance. It turns out that neither alternative expectation formation behaviour nor financial frictions can systematically increase the forecasting performance of basic DSGE models. Financial frictions improve forecasts only during periods of financial crises. However, traditional price and wage rigidities systematically help to increase the forecasting performance.

Konjunktur aktuell: Aufschwung in Deutschland setzt sich trotz nachlassender Impulse aus dem Ausland fort

Hans-Ulrich Brautzsch João Carlos Claudio Andrej Drygalla Franziska Exß Katja Heinisch Oliver Holtemöller Martina Kämpfe Axel Lindner Jan-Christopher Scherer Birgit Schultz Matthias Wieschemeyer Götz Zeddies

in: Konjunktur aktuell, No. 3, 2018

Abstract

Im Herbst 2018 ist die Weltkonjunktur weiterhin recht kräftig. Allerdings haben die regionalen Differenzen seit Jahresbeginn zugenommen. Während der Aufschwung in den USA auch wegen des starken Impulses durch die dortige Steuerreform noch einmal an Kraft gewonnen hat, ist die Konjunktur im Euroraum etwas schwächer geworden. Der Welthandel hat seit Jahresbeginn kaum noch zugelegt. Eine Ursache dieser Stagnation ist die Verschlechterung der handelspolitischen Rahmenbedingungen. Die Handelskonflikte sind allerdings nur einer von mehreren Risikofaktoren für die deutsche Konjunktur. Hinzu kommen die Möglichkeit eines ungeordneten Austritts Großbritanniens aus der EU im Frühjahr 2019 sowie ein weiterer Verlust an Vertrauen der Finanzmärkte in die Solvenz des italienischen Staates, falls die Regierung Italiens ihre finanzpolitischen Vorhaben in großem Stil umsetzt. Die deutsche Wirtschaft ist seit fünf Jahren im Aufschwung. Wichtige Treiber sind die außerordentlich günstigen Finanzierungsbedingungen und eine starke Expansion der Beschäftigung. Zuletzt hat die Nachfrage aus dem Ausland allerdings an Schwung verloren. Dabei spielt auch die Verteuerung deutscher Produkte aufgrund der Aufwertung des Euro seit dem Frühjahr 2017 eine Rolle. Die in diesem Jahr und besonders im Jahr 2019 expansiv ausgerichtete Finanzpolitik verschafft der Konjunktur Rückenwind, aber hohe Kapazitätsauslastungen und Engpässe beim Beschäftigungsaufbau dürften eine weitere kräftige Expansion behindern. Das reale Bruttoinlandsprodukt liegt nach vorliegender Prognose im Jahr 2018 um 1,8% höher als im Vorjahr, im Jahr 2019 beträgt die Rate 1,7%. Die ostdeutsche Wirtschaft expandiert in diesem Jahr um 1,5% und im Jahr 2019 um 1,4%.

Zum Risiko einer Staatsschuldenkrise in Italien

Oliver Holtemöller Tobias Knedlik Axel Lindner

in: IWH Online, No. 4, 2018

Abstract

Die wirtschaftliche Entwicklung Italiens war in den vergangenen Jahren durch eine ausgesprochen schwache Produktivitätsentwicklung gekennzeichnet. Das Bruttoinlandsprodukt je Einwohner beträgt nur 92% des Niveaus im Jahr 2007, während es im Euroraum insgesamt (inklusive Italien) bei 103% des Vorkrisenniveaus von 2007 liegt. Die Staatsschuldenquote ist im Zeitraum von 2007 bis 2017 von 100% in Relation zum Bruttoinlandsprodukt um 30 Prozentpunkte auf 130% gestiegen. Es bestehen daher Zweifel, ob die Wirtschaftskraft Italiens ausreichend ist, um die weiter steigenden Staatsschulden künftig bedienen zu können. Diese Zweifel kommen zum Beispiel in der gegenwärtig (August 2018) um gut 3 Prozentpunkte höheren Umlaufsrendite 10-jähriger italienischer Staatsanleihen im Vergleich zu deutschen Staatsanleihen zum Ausdruck. Die Regierung Italiens will der Wirtschaft durch expansive Finanzpolitik wieder auf die Beine helfen. Im vorliegenden Beitrag wird die Tragfähigkeit der italienischen Staatsverschuldung für verschiedene Szenarien analysiert. Dabei gibt es je nach den getroffenen Annahmen zu wichtigen Wirkungszusammenhängen eine ganze Bandbreite von möglichen Entwicklungen, die aber allesamt eine deutlich expansive Finanzpolitik für Italien nicht ratsam erscheinen lassen, weil sie insgesamt nicht förderlich für die Stabilisierung der Staatsverschuldung wäre. Vielmehr sollten produktivitätssteigernde Strukturreformen umgesetzt werden, die dann auch moderat höhere Staatsausgaben erlauben würden.

Global Food Prices and Monetary Policy in an Emerging Market Economy: The Case of India

Oliver Holtemöller Sushanta Mallick

in: 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.

On the Distribution of Refugees in the EU

Martin Altemeyer-Bartscher Oliver Holtemöller Axel Lindner Andreas Schmalzbauer Götz Zeddies

in: Intereconomics, No. 4, 2016

Abstract

The current situation regarding the migration of refugees can only be handled efficiently through closer international cooperation in the field of asylum policy. From an economic point of view, it would be reasonable to distribute incoming refugees among all EU countries according to a distribution key that reflects differences in the costs of integration in the individual countries. An efficient distribution would even out the marginal costs of integrating refugees. In order to reach a political agreement, the key for distributing refugees should be complemented by compensation payments that distribute the costs of integration among countries. The key for distributing refugees presented by the EU Commission takes account of appropriate factors in principle, but it is unclear in terms of detail. The compensation payments for countries that should take relatively high numbers of refugees for cost efficiency reasons should be financed by reallocating resources within the EU budget.

Impact of Personal Economic Environment and Personality Factors on Individual Financial Decision Making

S. Prinz G. Gründer R. D. Hilgers Oliver Holtemöller I. Vernaleken

in: Frontiers in Decision Neuroscience, No. 158, 2014

Abstract

This study on healthy young male students aimed to enlighten the associations between an individual’s financial decision making and surrogate makers for environmental factors covering long-term financial socialization, the current financial security/responsibility, and the personal affinity to financial affairs as represented by parental income, funding situation, and field of study. A group of 150 male young healthy students underwent two versions of the Holt and Laury (2002) lottery paradigm (matrix and random sequential version). Their financial decision was mainly driven by the factor “source of funding”: students with strict performance control (grants, scholarships) had much higher rates of relative risk aversion (RRA) than subjects with support from family (ΔRRA = 0.22; p = 0.018). Personality scores only modestly affected the outcome. In an ANOVA, however, also the intelligence quotient significantly and relevantly contributed to the explanation of variance; the effects of parental income and the personality factors “agreeableness” and “openness” showed moderate to modest – but significant – effects. These findings suggest that environmental factors more than personality factors affect risk aversion.

The Economic Development of Saxony-Anhalt since 1990

Oliver Holtemöller Axel Lindner

in: IWH Discussion Papers, No. 6, 2018

Abstract

This article describes the economic development of Saxony-Anhalt since 1990 in the context of the East German transition from a centrally planned economy to a market economy. In the early 1990s the economy of Saxony-Anhalt caught up quickly with West Germany, mainly because the capital stock was modernized and expanded. Convergence, however, has almost come to a halt for some time now and gross domestic product per employed person is still about 20% below the West German level. The challenge for economic policy is to further the catching-up process by fostering research and innovation and improving the skills of the workforce.

Zu den rentenpolitischen Plänen im Koalitionsvertrag 2018 von CDU, CSU und SPD: Konsequenzen, Finanzierungsoptionen und Reformbedarf

Oliver Holtemöller Christoph Schult Götz Zeddies

in: IWH Discussion Papers, No. 5, 2018

Abstract

In the coalition agreement from February 7, 2018, the new German federal government drafts its public pension policy, which has to be evaluated against the background of demographic dynamics in Germany. From the year 2020 onwards, the age structure of the German population will change significantly. In this paper, the consequences of public pensions related policy measures from the coalition agreement for the German public pension insurance are illustrated using a simulation model. In the long run, the intended extensions of benefits would lead to an increase in the contribution rate to the German public pension insurance of about two and a half percentage points. Referring to pension systems of other countries, we discuss measures in order to limit this increase in the contribution rate.
