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, Nr. 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.

Credit Card Entrepreneurs

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

in: IWH Discussion Papers, Nr. 5, 2025

Abstract

<p>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.</p>

Reassessing EU Comparative Advantage: The Role of Technology

Filippo di Mauro Marco Matani Gianmarco Ottaviano

in: IWH Discussion Papers, Nr. 26, 2024

Abstract

<p>Based on the sufficient statistics approach developed by Huang and Ottaviano (2024), we show how the state of technology of European industries relative to the rest of the world can be empirically assessed in a way that is simple in terms of computation, parsimonious in terms of data requirements, but still comprehensive in terms of information. The lack of systematic cross-industry correlation between export specialization and technological advantage suggests that standard measures of revealed comparative advantage only imperfectly capture a country’s technological prowess due to the concurrent influences of factor prices, market size, markups, firm selection and market share reallocation.</p>

From Labor to Intermediates: Firm Growth, Input Substitution, and Monopsony

Matthias Mertens Benjamin Schoefer

in: IWH Discussion Papers, Nr. 24, 2024

Abstract

<p>We document and dissect a new stylized fact about firm growth: the shift from labor to intermediate inputs. This shift occurs in input quantities, cost and output shares, and output elasticities. We establish this fact using German firm-level data and replicate it in administrative firm data from 11 additional countries. We also document these patterns in micro-aggregated industry data for 20 European countries (and, with respect to industry cost shares, for the US). We rationalize this novel regularity within a parsimonious model featuring (i) an elasticity of substitution between intermediates and labor that exceeds unity, and (ii) an increasing shadow price of labor relative to intermediates, due to monopsony power over labor or labor adjustment costs. The shift from labor to intermediates accounts for one half to one third of the decline in the labor share in growing firms (the remainder is due to wage markdowns and markups) and rationalizes most of the labor share decline in growing industries.</p>

Declining Job Reallocation in Europe: The Role of Shocks, Market Power, and Technology

Filippo Biondi Sergio Inferrera Matthias Mertens Javier Miranda

in: IWH Discussion Papers, Nr. 19, 2023

Abstract

<p>We study changes in job reallocation in Europe after 2000 using novel microaggregated data that we collected for 19 European countries. In all countries, we document broad-based declines in job reallocation rates that concern most economic sectors and size classes. These declines are mainly driven by dynamics within sectors, size, and age classes rather than by compositional changes. Simultaneously, employment shares of young firms decline. Consistent with US evidence, firms’ employment has become less responsive to productivity shocks. However, the dispersion of firms’ productivity shocks has decreased too. To enhance our understanding of these patterns, we derive and apply a firm-level framework that relates changes in firms’ market power, labor market imperfections, and production technology to firms’ responsiveness and job reallocation. Using German firm-level data, we find that changes in markups and labor output elasticities, rather than adjustment costs, are key in rationalizing declining responsiveness.</p>

Intuit QuickBooks Small Business Index: A New Employment Series for the US, Canada, and the UK

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

in: IWH Discussion Papers, Nr. 9, 2023

Abstract

Small and young businesses are essential for job creation, innovation, and economic growth. Even most of the superstar firms start their business life small and then grow over time. Small firms have less internal resources, which makes them more fragile and sensitive to macroeconomic conditions. This suggests the need for frequent and real-time monitoring of the small business sector’s health. Previously this was difficult due to a lack of appropriate data. This paper fills this important gap by developing a new Intuit QuickBooks Small Business Index that focuses on the smallest of small businesses with at most 9 workers in the US and the UK and at most 19 workers in Canada. The Index aggregates a sample of anonymous Quick- Books Online Payroll subscriber data (QBO Payroll sample) from 333,000 businesses in the US, 66,000 in Canada, and 25,000 in the UK. After comparing the QBO Payroll sample data to the official statistics, we remove the seasonal components and use a Flexible Least Squares method to calibrate the QBO Payroll sample data against official statistics. Finally, we use the estimated model and the QBO Payroll sample data to generate a near real-time index of economic activity. We show that the estimated model performs well both in-sample and out-of-sample. Additionally, we use this analysis for different regions and industries. Keywords:
