We show an equivalence result in the standard representative agent New Keynesian model after demand, wage markup and correlated price markup and TFP shocks: assuming sticky prices and flexible wages yields identical allocations for GDP, consumption, labor, inflation and interest rates to the opposite case- flexible prices and sticky wages. This equivalence result arises if the price and wage Phillips curves' slopes are identical and generalizes to any pair of price and wage Phillips curve slopes such that their sum and product are identical. Nevertheless, the cyclical implications for profits and wages are substantially different. We discuss how the equivalence breaks when these factor-distributional implications matter for aggregate allocations, e.g. in New Keynesian models with heterogeneous agents, endogenous firm entry, and non-constant returns to scale in production. Lastly, we point to an econometric identification problem raised by our equivalence result and discuss possible solutions thereof.

*** Steigende Sozialabgaben und Inflation fressen Gehaltsplus der Beschäftigten bei Bund und Kommunen auf *** Die Tarifvertragsparteien des Öffentlichen Dienstes von Bund und Kommunen haben sich am vergangenen Wochenende auf einen neuen Tariflohnabschluss mit einer Laufzeit von 27 Monaten geeinigt: Demnach steigen im April 2025 die Löhne um 3,0%, jedoch mindestens um 110 Euro je Monat. Im Mai 2026 gibt es dann nochmals eine Tariflohnerhöhung um 2,8% sowie eine Erhöhung der Jahressonderzahlung und ab 2027 einen zusätzlichen Urlaubstag.

We measure desired labour supply at the extensive (employment) margin in two representative surveys of the U.S. and German populations. We elicit reservation raises: the percent wage change that renders a given individual indifferent between employment and nonemployment. It is equal to her reservation wage divided by her actual, or potential, wage. The reservation raise distribution is the nonparametric aggregate labour supply curve. Locally, the curve exhibits large short-run elasticities above 3, consistent with business cycle evidence. For larger upward shifts, arc elasticities shrink towards 0.5, consistent with quasi-experimental evidence from tax holidays. Existing models fail to match this nonconstant, asymmetric curve.

Standard labor market models assume that workers hold accurate beliefs about the external wage distribution, and hence their outside options with other employers. We test this assumption by comparing German workers’ beliefs about outside options with objective benchmarks. First, we find that workers wrongly anchor their beliefs about outside options on their current wage: workers that would experience a 10% wage change if switching to their outside option only expect a 1% change. Second, workers in low-paying firms underestimate wages elsewhere. Third, in response to information about the wages of similar workers, respondents correct their beliefs about their outside options and change their job search and wage negotiation intentions. Finally, we analyze the consequences of anchoring in a simple equilibrium model. In the model, anchored beliefs keep overly pessimistic workers stuck in low-wage jobs, which gives rise to monopsony power and labor market segmentation.

Das Mannheimer Unternehmenspanel verknüpft mit dem Betriebs-Historik-Panel (MUP-BHP) setzt sich aus Querschnittsdatensätzen ab dem Jahr 2010 zusammen. Jeder Querschnitt umfasst alle Gesellschaften mit beschränkter Haftung (GmbH) aus dem Mannheimer Unternehmenspanel (MUP) und deren Betriebsstätten des gesamtdeutschen Raumes, die in der Beschäftigten-Historik (BeH) zum Stichtag 31.12. erfasst sind. Diese Verknüpfung von Unternehmen und Betrieben liegt ein Record-Linkage der Adressdaten des vom Leibniz Institut für Europäische Wirtschaftsforschung gehaltenen MUP und der Betriebsadressdaten am IAB zugrunde. Die einzelnen Querschnittsdatensätze enthalten Informationen zu den Betrieben und Unternehmen sowie eine Zusatzdatei zu Gesellschaftern. Die Datensätze können zu einem Panel verbunden werden. Dieser Datenreport beschreibt das Mannheimer Unternehmenspanel verknüpft mit dem Betriebs-Historik-Panel (MUP-BHP) 2010–2020.

We analyze how skill transferability and the local industry mix affect the adjustment costs of workers hit by a trade shock. Using German administrative data and novel measures of economic distance we construct an index of labor market absorptiveness that captures the degree to which workers from a particular industry are able to reallocate into other jobs. Among manufacturing workers, we find that the earnings loss associated with increased import exposure is much higher for those who live in the least absorptive regions. We conclude that the local industry composition plays an important role in the adjustment processes of workers.
