Voice at Work

Abstract
We estimate the effects of worker voice on productivity, job quality, and separations. We study the 1991 introduction of a right to worker representation on boards or advisory councils in Finnish firms with at least 150 employees, designed primarily to facilitate workforce-management communication. Consistent with information sharing theories, our difference-in-differences design reveals that worker voice slightly raised labor productivity, firm survival, and capital intensity. In contrast to the exit-voice theory, we find no effects on voluntary job separations, and at most small positive effects on other measures of job quality. A 2008 introduction of shop-floor representation had similarly limited effects.

Demografischer Wandel, ausländische Beschäftigte und der Arbeitsmarkt Sachsen-Anhalts vor der Landtagswahl am 6. September 2026
Reint E. Gropp, Alexander Reifschneider
IWH Policy Notes,
No. 3,
2026
Abstract
Anfang September wählt Sachsen-Anhalt einen neuen Landtag, und die AfD hat erstmals die Chance auf eine eigene Regierungsmehrheit. Sachsen-Anhalt hat eine der ältesten Beschäftigtenstrukturen Deutschlands: Fast jeder dritte deutsche Beschäftigte ist 55 oder älter. Im vergangenen Jahrzehnt hat das Land netto bereits 40.580 deutsche Beschäftigte verloren. Die Beschäftigung blieb dennoch stabil, weil 51.960 ausländische Beschäftigte hinzukamen. Ein erheblicher Teil dieses Zuwachses stammt aus Fluchtkontexten: Seit Ende 2020 kamen rund 40% des Zuwachses aus Asylherkunftsländern und der Ukraine. Die internationale Evidenz zeigt nach Regierungswechseln zu zuwanderungskritischen Parteien Rückgänge des ausländischen Zuzugs zwischen 32 und 65%. Eine kompensierende Rückkehr Einheimischer ist nicht zu beobachten. Die Analyse zeigt, dass tausende von offenen Stellen in Sachsen-Anhalt nicht besetzt werden könnten, mit entsprechenden Auswirkungen auf Wohlstand und Wachstum.

Do Online Real Estate Listing Prices Gauge Transaction Prices (Well)? Evidence from Novel Near-Real-Time Data
Michael Koetter, Felix Noth, Fabian Woebbeking
IWH Discussion Papers,
No. 13,
2026
Abstract
We show that online listing prices closely approximate transaction prices across Europe. Our validation uses the IWH European Real Estate Index (EREI), a near-real-time database of monthly purchase prices, rents, listing counts, and time on market for 1,154 NUTS-3 regions in 16 countries since April 2024. With publication lags as short as one month, validated listing prices offer a timely, comparable complement to official house price statistics. Purchase price levels correlate between 0.94 and 0.97 with transaction prices in the five most populous markets, while calibration slopes range from 0.95 to 1.00. Aggregate listing prices exceed benchmark transaction prices by 13% to 22%.

The Effects of the Iberian Exception Mechanism on Wholesale Electricity Prices and Consumer Inflation: A Synthetic-controls Approach
Miguel Haro Ruiz, Christoph Schult, Christoph Wunder
Applied Economics Letters,
Vol. 33 (9),
2026
Abstract
This study employs synthetic control methods to estimate the effect of the Iberian exception mechanism on wholesale electricity prices and consumer inflation, for both Spain and Portugal. We find that the intervention led to an average reduction of approximately 40% in the spot price of electricity between July 2022 and June 2023 in both Spain and Portugal. Regarding overall inflation, we observe notable differences between the two countries. In Spain, the intervention has an immediate effect, and results in an average decrease of 3.5 percentage points over the twelve months under consideration. In Portugal, however, the impact is small and generally close to zero. Different electricity market structures in each country are a plausible explanation.

Transparency and Forecasting: The Impact of Conditioning Assumptions on Forecast Accuracy
Katja Heinisch, Christoph Schult, Carola Stapper
Applied Economics Letters,
Vol. 33 (5),
2026
Abstract
This study investigates the impact of inaccurate assumptions on economic forecast precision. We construct a new dataset comprising an unbalanced panel of annual German GDP forecasts from various institutions, taking into account their underlying assumptions. We explicitly control for different forecast horizons to reflect the information available at the time of release. Our analysis reveals that approximately 75% of the variation in squared forecast errors can be attributed to the variation in squared errors of the initial assumptions. This finding emphasizes the importance of accurate assumptions in economic forecasting and suggests that forecasters should transparently disclose their assumptions to enhance the usefulness of their forecasts in shaping effective policy recommendations.
