Abstract
In this paper, we discuss how environmental damage and emission reduction policies affect the conduct of monetary policy in a two-sector (clean and dirty) dynamic stochastic general equilibrium model. In particular, we examine the optimal response of the interest rate to changes in sectoral inflation due to standard supply shocks, conditional on a given environmental policy. We then compare the performance of a nonstandard monetary rule with sectoral inflation targets to that of a standard Taylor rule. Our main results are as follows: first, the optimal monetary policy is affected by the existence of environmental policy (carbon taxation), as this introduces a distortion in the relative price level between the clean and dirty sectors. Second, compared with a standard Taylor rule targeting aggregate inflation, a monetary policy rule with asymmetric responses to sector-specific inflation allows for reduced volatility in the inflation gap, output gap, and emissions. Third, a nonstandard monetary policy rule allows for a higher level of welfare, so the two goals of welfare maximization and emission minimization can be aligned.

Konjunktur aktuell: Deutsche Wirtschaft noch in der Defensive – aber erste Anzeichen für ein Ende des Abschwungs
Konjunktur aktuell,
No. 2,
2024
Abstract
Die Aussichten für die internationale Konjunktur bleiben leicht eingetrübt. In Europa setzt sich die zaghafte Erholung fort. In Deutschland vermehren sich die Anzeichen für eine konjunkturelle Besserung. Alles in allem wird die Produktion im Sommerhalbjahr wohl nur verhalten ausgeweitet, doch ab Herbst dürfte die Belebung Fahrt aufnehmen. Das Bruttoinlandsprodukt dürfte im Jahr 2024 um 0,3% expandieren, für 2025 prognostiziert das IWH einen Zuwachs um 1,5%.

Fiscal Policy under the Eyes of Wary Bondholders

IWH Discussion Papers,
No. 26,
2023
Abstract
This paper studies the interaction between fiscal policy and bondholders against the backdrop of high sovereign debt levels. For our analysis, we investigate the case of Italy, a country that has dealt with high public debt levels for a long time, using a Bayesian structural VAR model. We extend a canonical three variable macro mode to include a bond market, consisting of a fiscal rule and a bond demand schedule for long-term government bonds. To identify the model in the presence of political uncertainty and forward-looking investors, we derive an external instrument for bond demand shocks from a novel news ticker data set. Our main results are threefold. First, the interaction between fiscal policy and bondholders’ expectations is critical for the evolution of prices. Fiscal policy reinforces contractionary monetary policy through sustained increases in primary surpluses and investors provide incentives for “passive” fiscal policy. Second, investors’ expectations matter for inflation, and we document a Fisherian response of inflation across all maturities in response to a bond demand shock. Third, domestic politics is critical in the determination of bondholders’ expectations and an increase in the perceived riskiness of sovereign debt increases inflation and thus complicates the task of controlling price growth.

Konjunktur aktuell: Export und privater Konsum schwach – Deutschland wartet auf den Aufschwung
Konjunktur aktuell,
No. 4,
2023
Abstract
Die Weltwirtschaft verliert zum Ende des Jahres 2023 weiter an Schwung. Der durch den weltweiten Inflationsschub ausgelöste restriktive Schwenk der Geldpolitik drückt über höhere Finanzierungskosten vielerorts die Güternachfrage. Im nächsten Jahr dürfte die Weltwirtschaft wieder etwas anziehen. Die deutsche Wirtschaft ist nach Ende der Pandemie nicht wieder auf ihren alten Wachstumspfad zurückgekehrt. Das Verarbeitenden Gewerbe hat an Wettbewerbsfähigkeit eingebüßt, und die Weltnachfrage nach Industriegütern ist zurzeit schwach. Zudem ist die Inflation immer noch hoch, und die Realeinkommen sind längere Zeit über zurückgegangen. Die geldpolitische Straffung hat die Finanzierungsbedingungen verschlechtert, was besonders die Bauwirtschaft belastet. Das Bruttoinlandsprodukt wird 2023 wohl um 0,3% sinken und im kommenden Jahr um 0,5% expandieren.

AIECE General Report, Part 2, Spring 2023
Andrej Drygalla, Axel Lindner, Birgit Schultz
IWH Studies,
No. 4,
2023
Abstract
The Halle Institute for Economic Research (IWH) is a member of AIECE (Association d'Instituts Europeens de Conjoncture Economique/Association of European Conjuncture Institutes), an association of independent European institutes involved in surveying economic conditions and developments, and in short-term macroeconomic forecasting. The main objective of the Association is to stimulate the exchanges between its members with a view to improve their insight into international economic developments. This ranges from the exchange of statistical or institutional information to discussions on economic policy Guidelines to common research activities. The AIECE organises between its members an exchange of view, of information and of literature on international economic developments, in particular in Europe. The Association provides the framework for joint activities of its members in areas of common interest. Its structure allows its members to develop common views on the future cyclical development. In order to meet these objectives the Association has half-yearly plenary meetings, centred around a general report on the European conjuncture prepared in turn by one of the members in cooperation with the other member institutes, but also with discussions of the working group reports and of special surveys prepared by member institutes. In Spring 2023, the report was written by the Halle Institute for Economic Research (IWH).
