This paper develops a dynamic model in which the productivity of joint research governs strategic investment timing in innovation races. Departing from the standard assumption that discovery rates scale proportionally with the number of active firms, we allow research to exhibit decreasing or...

This paper reviews the contributions of the 2025 Nobel Prize in Economics laureates, Joel Mokyr, Philippe Aghion and Peter Howitt, to our understanding of innovation-driven economic growth, situating their work within the broader evolution of modern growth theory and empirical evidence. It...

Die Studie untersucht die technologische Leistungsfähigkeit Deutschlands im internationalen Vergleich anhand von Daten zur sektoralen Wertschöpfung sowie mittels Daten zum Handel mit Industriegütern. Sie zeigt, dass die deutsche Wirtschaft weiterhin stark auf die Produktion hochwertiger...

Defensive hiring of researchers by incumbent firms with monopsony power reduces creative destruction. This mechanism helps explain the simultaneous rise in R&D spending and decline in TFP growth in the US economy over recent decades. We develop a simple model highlighting the critical role of...

Uncertainty about the value of a contested innovation induces leaders and laggards to update their expectations in opposite directions. We characterize situations in which firms that have obtained an initial advantage are not the most likely to achieve final success. In spite of amplifying a...

This study explores the impact of competition on innovation in Vietnam, using a probit model with a binary dependent variable to measure product innovation outcomes. The competition variable is calculated using the adjusted Herfindahl-Hirschman Index. The study uses data from the 2021 enterprise...

This report examines the global race for 5G and 6G leadership through a comparative analysis of regulation, R&D investment, patenting, and the rollout of next-generation networks and services across Europe, the United States, and Asia. The United States leads in digital services and...

We study the interaction of customer capital and productivity through brand reallocation across firms. We develop a firm dynamics model with brands as transferable customer capital, heterogeneous firm productivity, and variable markups. We study the matching process between transferable brand...

Artificial intelligence (AI) is considered to be a key driver in the emerging sixth wave of technological advancement, one that has profound economic implications. The emergence of AI has led to significant changes in a wide range of different sectors, the reshaping of existing sectors, and the...

During the Second Industrial Revolution and subsequently, it is widely believed that Black Americans contributed disproportionately little to the economic development of the United States, especially in comparison to European Americans and immigrants from Europe. Yet, Black Americans tended to...

The primary objective of this paper is to develop a two-country, dynamic, general equilibrium model with innovation contests to formally analyze the impact of globalization on the skill premium and fully-endogenous growth. Higher quality products are endogenously discovered through stochastic...

This paper develops a two-country, dynamic general equilibrium model with innovation contests to study the impact of globalization on the skill premium and fully-endogenous growth. Higher quality products are endogenously discovered through stochastic and sequential global innovation contests in...

In dieser Studie wird die technologische Leistungsfähigkeit Deutschlands im internationalen Vergleich untersucht. Sie zeigt, dass die deutsche Wirtschaft relativ stark auf die FuE-intensiven Industrien und wissensintensiven Dienstleistungen spezialisiert ist. Dies verdankt sie vor allem der...

We study the optimal design of an innovation contest where the designer wants to induce product variety and faces a moral hazard problem. The innovators have different areas of expertise and may differ in their flexibility to adopt approaches outside their specialties. When the suppliers are...

For a long time, a prevailing view was that due to the dynamic nature of competition in digital markets intervention by antitrust authorities would do more harm than good. It was assumed that the permanent risk of disruptive innovations, Joseph Schumpeter’s “perennial gale of creative...

Markets for technology provide a vibrant channel through which firms purchase ownership rights to patented inventions. Although such transactions enable firms to secure access to intangible assets originating beyond their borders, they also provide cues to competitors regarding the purchasing...
