Progressive Tax-like Effects of Inflation: Fact or Myth? The U.S. Post-war Experience

Matthias Wieschemeyer, Bernd Süssmuth
IWH Discussion Papers, Nr. 33, 2017
Abstract
Inflation and earnings growth can push some tax payers into higher brackets in the absence of inflation-indexed schedules. Moreover, inflation may affect the composition of individuals’ income sources. As a result, depending on the relative tax burden of labour and capital, inflation may decrease or increase the difference between before-tax and after-tax income. However, whether some and if so which percentiles of the income distribution net benefit from inflation via taxation is a widely unexplored question. We make use of a novel dataset on U.S. pre-tax and post-tax income distribution series provided by Pike ty et al. (2018) for the years 1962 to 2014 to answer this question. To this end, we estimate local projections to quantify dynamic effects. We find that inflation shocks increase progressivity of taxation not only contemporaneously but also with some repercussion of several years after the shock. While particularly the bottom two quintiles gain in share, it is not the top but the fourth quintile that lastingly loses.

EFN Report Winter 2017/18: Economic Outlook for the Euro Area in 2018 and 2019

EFN Reports, Nr. 1, 2018
Abstract
With advanced economies likely to face over-utilization of economic capacities in 2018 for the first time since the Great Recession, companies will further expand their investment activities. Price and wage dynamics will pick up globally, triggered by the recent increase in energy prices. A major risk for the world economy pertains to financial markets: measures for risk tolareance and valuations for many types of assets have approached levels last reached ten years ago, on the eve of the financial crisis. A sudden readjustment of asset prices and risk premia could worsen financial conditions globally and seriously affect the global economy. The cyclical upswing of the euro area economy continues. The recovery, under way since summer 2013, transformed into an upswing in autumn 2016 when demand from outside the euro area increased quite abruptly; higher exports and improved expectations have contrinuted to induce firms to invest more into equipment. Wage dynamics in the euro area appear to increase, but only slowly. An annual growth rate for hourly wage costs of about 2% is still not enough to put upward pressure on prices, but this will change eventually as the cyclical upswing is likely to continue. Inflation will, according to our forecast, reach the ECB’s target of below but close to 2% in the second half of 2019. Conditions for further healthy growth in the euro area are in place, but employment dynamics might markedly lose momentum in some member countries in the second half of 2018, as the potential labour force is becoming more and more exhausted. Overall, we forecast euro area GDP to grow by 2.2% in 2018 and by 1.5% in 2019.

EFN Report Autumn 2017: Economic Outlook for the Euro Area in 2017 and 2018

EFN Reports, Nr. 4, 2017
Abstract
In 2017 the world economy is in an upswing, but consumer price inflation is still surprisingly low in advanced economies, and central banks will therefore keep key interest rates very low and financial conditions favorable for the rest of the year and, probably, for 2018. Global growth, though, will moderate a bit, since expansive policy measures in China have been reduced. As an early consequence, imports of emerging Asia were no more than stagnant during summer. The upswing in the euro area is broad based, both regionally and with respect to the different components of aggregate demand, as investment has recently picked up markedly, partly due to construction of dwellings. From the production side, the level of capacity utilization in the manufacturing sector is clearly above its long-term average and rising further. Inflation will not have reached the ECB’s target rate of below but close to 2% at the end of 2018. The trend of a growing participation rate in labour markets and the amount of part-time and low quality jobs are some reasons why overall wage and price dynamics are still very moderate; the appreciation of the euro, the incorporation of technical innovations and a possible change in the consumer preferences for low-cost products could be other reasons. We forecast a GDP growth rate of 2.3% for 2017 and 1.9% for 2018. This year’s strong pickup of world trade means that net exports will, in spite of rather strong domestic demand, contribute positively to GDP growth in 2017, while the opposite holds for 2018, due to the significant appreciation of the Euro.

Gemeinschaftsdiagnose Herbst 2017: Aufschwung weiter kräftig – Anspannungen nehmen zu

Der Aufschwung der deutschen Wirtschaft hat an Stärke und Breite gewonnen. Neben den Konsumausgaben tragen nun auch das Auslandsgeschäft und die Investitionen zur Expansion bei. Das haben die an der Gemeinschaftsdiagnose beteiligten Wirtschaftsforschungsinstitute in ihrem Herbstgutachten für die Bundesregierung ermittelt. Die sehr hohe konjunkturelle Dynamik in der ersten Hälfte des laufenden Jahres wird sich zwar etwas abschwächen. Gleichwohl nimmt die Wirtschaftsleistung in diesem und im nächsten Jahr stärker zu als die Produktionskapazitäten wachsen. Im Ergebnis steigt die gesamtwirtschaftliche Auslastung, und die Wirtschaftsleistung liegt über dem Produktionspotenzial. Das Bruttoinlandsprodukt dürfte in diesem Jahr um 1,9 Prozent und im nächsten Jahr um 2 Prozent zulegen (kalenderbereinigt 2,2 bzw. 2,1 Prozent).

Zur Stabilisierung von Rentenniveau und Rentenversicherungsbeitrag

Oliver Holtemöller, Götz Zeddies
IWH Online, Nr. 2, 2017
Abstract
Ursprünglich galt die Sicherung des Lebensstandards nach dem Ausscheiden aus dem Erwerbsleben als zentrale Aufgabe der gesetzlichen Rentenversicherung. In der öffentlichen Diskussion gilt deshalb der Entwicklung des Rentenniveaus, welches das Verhältnis der Standardrente zum durchschnittlichen Arbeitsentgelt wiedergibt, besondere Aufmerksamkeit. Ein kontinuierlich sinkendes Rentenniveau wird häufig als nicht hinnehmbar angesehen, weil dadurch soziale Härten entstehen können. Aufgrund des demographischen Wandels, der sich in den kommenden Jahren beschleunigen wird, ginge eine Fixierung des Rentenniveaus jedoch mit einem deutlichen Anstieg des Beitragssatzes zur gesetzlichen Rentenversicherung und damit der Lohnnebenkosten einher. Mit dem Altersvermögens- und dem Altersvermögensergänzungsgesetz wurde deshalb ab dem Jahr 2001 ein Paradigmenwechsel in der gesetzlichen Rentenversicherung vollzogen. So wurde unter anderem ein Nachhaltigkeitsfaktor in die Rentenanpassungsformel aufgenommen, welcher die Rentenanpassung bei einer Alterung der Bevölkerung dämpft. Für das Rentenniveau wurde lediglich eine Untergrenze von 43% im Jahr 2030 festgelegt; der Beitragssatz soll bis dahin die Obergrenze von 22% nicht übersteigen.

Reformvorschlag: Renten künftig an Verbraucherpreise koppeln

Bislang orientiert sich die jährliche Anpassung der Renten in Deutschland vor allem an der Entwicklung der Bruttolöhne und -gehälter. Ein Nachhaltigkeitsfaktor in der Rentenanpassungsformel berücksichtigt zudem den demographischen Wandel, dämpft also die Rentenanpassung bei einer Alterung der Bevölkerung – allerdings bislang nicht genug, um trotz eines sinkenden Rentenniveaus einen deutlichen Anstieg der Beiträge in der Zukunft zu verhindern. Zu dem bestehenden System gibt es durchaus Alternativen. So könnte das Rentenniveau bei Renteneintritt auf dem heutigen Niveau oder sogar etwas darüber fixiert werden und dennoch der Beitragsanstieg gedämpft werden, wenn die Renten derjenigen, die bereits in Rente sind, nur noch mit der Inflationsrate steigen. Der Lebensstandard bliebe dadurch erhalten, so lautet ein Vorschlag Oliver Holtemöllers, Leiter der Abteilung Makroökonomie und Vizepräsident am Leibniz-Institut für Wirtschaftsforschung Halle (IWH).

EFN Report Summer 2017: Economic Outlook for the Euro Area in 2017 and 2018

EFN Reports, Nr. 3, 2017
Abstract
• Worldwide economic activity is vivid in summer 2017. Data on production for the first quarter of the year were only mixed: in the euro area quarterly growth was accelerating, but it went down in the US, Japan, and China. Other basic indicators, however, suggest that these economies continue expanding healthily. • Risks concerning the international economic policy framework remain, in particular since the economic agenda of the US government is still unclear, and no one knows whether the Brexit negotiations will lead the way to an orderly separation of Britain from the EU. • Production in the euro area has been expanding by more that 1 ½ % per year for almost three years now; since summer 2016, this expansion has even gained a bit of pace, mainly due to a expansion in France and, to a lesser extent, in Italy. • The ECB’s cautious hints at a coming normalization of monetary policy were enough to have a discernible effect on financial conditions at the end of June: yields for long term bonds rose, and the euro appreciated. That said, the common currency is still relatively cheap, and borrowing costs for non-financial firms and private households are still low. • Overall, we raise our GDP forecast for 2017 from 1.7% (spring report) to 2.1% and for 2018 to 1.8% (spring: 1.7%). We expect HICP inflation to remain well below the ECB target both in 2017 and 2018. • A major risk for the continuation of the current upswing in 2018 comes from the normalization of monetary policy: it is not clear by how much long term interests will rise and whether higher borrowing costs will jeopardize the confidence of financial markets in the solvency of some public debtors in the euro area.

Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks

Andrej Drygalla
IWH Discussion Papers, Nr. 14, 2017
publiziert in: Review of World Economics
Abstract
Russian monetary policy has been challenged by large and continuous private capital outflows and a sharp drop in oil prices during 2014, with both ongoings having put a significant depreciation pressure on the ruble and having led the central bank to eventually give up its exchange rate management strategy. Against this background, this paper estimates a small open economy model for Russia, featuring an oil price sector and extended by a specification of the foreign exchange market to correctly account for systematic central bank interventions. We find that shocks to the oil price and private capital flows substantially affect domestic variables such as inflation, output and the exchange rate. Simulations of the model for the estimated actual strategy and five alternative regimes suggest that the vulnerability of the Russian economy to external shocks can substantially be lowered by adopting some form of an inflation targeting strategy. Foreign exchange intervention-based policy strategies to target the nominal exchange rate or the ruble price of oil, on the other hand, prove inferior to the policy in place.

Inflation Dynamics During the Financial Crisis in Europe: Cross-sectional Identification of Long-run Inflation Expectations

Geraldine Dany-Knedlik, Oliver Holtemöller
IWH Discussion Papers, Nr. 10, 2017
Abstract
We investigate drivers of Euro area inflation dynamics using a panel of regional Phillips curves and identify long-run inflation expectations by exploiting the crosssectional dimension of the data. Our approach simultaneously allows for the inclusion of country-specific inflation and unemployment-gaps, as well as time-varying parameters. Our preferred panel specification outperforms various aggregate, uni- and multivariate unobserved component models in terms of forecast accuracy. We find that declining long-run trend inflation expectations and rising inflation persistence indicate an altered risk of inflation expectations de-anchoring. Lower trend inflation, and persistently negative unemployment-gaps, a slightly increasing Phillips curve slope and the downward pressure of low oil prices mainly explain the low inflation rate during the recent years.
