Entrepreneurship, Innovation und Produktivitätswachstum

Diese Gruppe befasst sich mit Forschungsthemen, die für unser Verständnis von Innovationsmustern und Produktivitätswachstum von Bedeutung sind, und untersucht die Auswirkungen auf Arbeitnehmer und Unternehmen. Zu den Schwerpunkten gehören der Rückgang der Unternehmensdynamik, die Zunahme der Automatisierung, Entrepreneurship und Innovation sowie Lieferketten.

Labor Market Analysis and Public Policy: The Case of Morocco

Guillermo Hakim Julia Lane Javier Miranda

in: World Bank Economic Review, Vol. 13 (3), 1999

Abstract

This article uses detailed industry and household data to understand why Morocco's labor market performed poorly in 1985–95. The data indicate that marked structural changes and weak demand in the product market were responsible. This article makes two contributions to the literature. The first is specific: it underscores that the demand for labor is a derived demand and that the performance of the product market is an important determinant of the performance of the labor market. The second is more general: it demonstrates that this kind of microeconomic analysis, using data sets that are often available in developing countries, can inform policy design.

Safety in Unemployment and Risky Experimentation of Young Firms

Renato Faccini Seho Kim Javier Miranda

in: IWH Discussion Papers, Nr. 15, 2026

Abstract

We develop a theory in which a lower cost of job loss reduces the compensating wage premium workers require to join risky young firms. Lower labor costs encourage high-upside experimentation and raise productivity. Because experimentation is not directly observable, we exploit its life-cycle structure: experimentation risk is concentrated among young firms and resolved as firms mature. Using Danish matched employer-employee data and labor-market variation, we show that higher job-finding rates are associated with a lower young-mature wage differential. A randomized survey experiment supports the mechanism: worsening unemployment prospects increases the premium workers require to accept employment at higher-failure-risk young firms.

The Micro-aggregated Phillips Curve

Daniele Aglio Eric Bartelsman

in: IWH Discussion Papers, Nr. 11, 2026

Abstract

This paper provides theory and evidence on micro-level pricing behavior needed to model an aggregate New Keynesian Phillips Curve. We start with individual firms that are heterogeneous in their production technology and in the demand curves they face. We estimate the parameters of supply and demand curves by utilizing prices and quantities of outputs and factor inputs of firms along with exogenous downstream demand instruments from global input-output and trade data. The research addresses model heterogeneity using a clustering method to classify firms according to their production technology and observed price pass-through. The results show that more productive firms exhibit a lower price response to changes in demand. We find that the aggregate price response to demand shocks will be smaller when more productive firms absorb a larger portion of demand shocks, which generally is the case. At the same time, our results imply that idiosyncratic shifts in demand to clusters of firms with more rapidly rising marginal cost curves, or cost shocks to clusters of firms with high pass-through, will result in a higher aggregate price response. Finally, this paper provides a framework to incorporate heterogeneous pricing behavior into an estimate of the slope of the aggregate Phillips Curve.

Intangible Assets and Imperfections in Product and Labor Markets

Eric Bartelsman Sabien Dobbelaere Alessandro Zona Mattioli

in: IWH Discussion Papers, Nr. 5, 2026

Abstract

This paper develops a micro-founded framework linking price-cost and wage markups to intangible assets. Intangible assets, once created, are a source of firm rents. Owing to limits to enforceable ownership and the non-rival nature of knowledge, these rents can be both retained by the origin firm and transferred to a competitor through poaching of workers. Search and matching frictions affect labor mobility and result in bargaining over rents between the firm and the worker. This environment generates hold-up in intangible asset creation and motivates rent sharing. Under non-compete agreements, poached workers face start delays that weaken outside options. Using microdata from the Netherlands, we document higher price-cost and wage markups in more intangible-intensive firms and lower wages for workers with non-compete agreements, consistent with the model.

Minimum Wages and Rise of the Robots

Erik Brynjolfsson J. Frank Li Javier Miranda Robert Seamans Andrew J. Wang

in: NBER Working Paper, Nr. 34895, 2026

Abstract

This paper studies how minimum wage policy affects firms’ adoption of automation technologies. Using both state-level measures of robot exposure and novel plant-level data on industrial robot imports linked to U.S. Census microdata from 1992–2021, we show that increases in minimum wages raise the likelihood of robot adoption in manufacturing. Our preferred identification exploits discontinuities at state borders, comparing otherwise similar firms exposed to different wage floors. Across specifications, a 10 percent increase in the minimum wage increases robot adoption by roughly 8 percent relative to the mean.

Credit Card Entrepreneurs

Ufuk Akcigit Raman Chhina Seyit Cilasun Javier Miranda Nicolas Serrano-Velarde

in: IWH Discussion Papers, Nr. 5, 2025

Abstract

Utilizing near real-time QuickBooks data from over 1.6 million small businesses and a targeted survey, this paper highlights the critical role credit card financing plays for small business activity. We examine a two year period beginning in January of 2021. A turbulent period during which, credit card usage by small U.S. businesses nearly doubled, interest payments rose by 60%, and delinquencies reached 2.8%. We find, first, monthly credit card payments were up to three times higher than loan payments during this time. Second, we use targeted surveys of these small businesses to establish credit cards as a key financing source in response to firm-level shocks, such as uncertain cash flows and overdue invoices. Third, we establish the importance of credit cards as an important financial transmission mechanism. Following the Federal Reserve’s rate hikes in early 2022, banks cut credit card supply, leading to a 15.75% drop in balances and a 10% decline in revenue growth, as well as a 1.5% decrease in employment growth among U.S. small businesses. These higher rates also rendered interest payments unsustainable for many, contributing to half of the observed increase in delinquencies. Lastly, a simple heterogeneous firm model with a cash-in-hand constraint illustrates the significant macroeconomic impact of credit card financing on small business activity.
