We revisit the limited stock market participation puzzle leveraging a qualitative research approach that is commonly used in many social sciences, but much less so in economics or finance. We conduct in-depth interviews of stock market investors and non-investors in Germany, a highincome country...

The retail payment industry is significant, affects every citizen and is a very precondition for a modern society based on the division of labor. It is characterized by two-sidedness, strong network effects, high fixed costs, high concentration and high profitability of successful firms,...

Expectations are central to models of economic and financial decision-making. Yet in practice, individuals are often inattentive and, when asked, report fragile, context-dependent expectations that are only weakly linked to decisions. This raises the question to what extent they hold such...

This article advances a new perspective on corporate purpose, grounded in the institutional conditions under which corporate privileges are granted. Using a novel dataset of historical UK royal charters and a mixed-methods empirical strategy, the study shows that early corporations articulated...

We identify desirable/undesirable inflation outcomes under subjective beliefs by comparing surveybased and risk-adjusted distributions of inflation. Intuitively, investors dislike inflation at both extremes, preferring a range in the middle. This "good inflation" region, which investors...

I study the credit channel of the electric-vehicle (EV) transition using more than 1.8 million German auto loans and leases. I show that EV financing contracts default significantly less often than comparable internal combustion engine vehicle (ICEV) contracts-particularly among lower-income...

This paper examines the limits of corporate governance as a tool for advancing climate transition. While capital market mechanisms, shareholder stewardship, say-on-climate votes, and ESG-linked executive compensation are often presented as effective levers for greening corporate behavior, their...

This paper analyses the role of layering in the architecture of money and payment systems and how recent technological innovations affect it. Layering in payments, whereby payment ledgers are hierarchical to each other, and senior ledgers allow for interoperability between junior ledgers, has...

We leverage multimodal large language models (LLMs) to construct a dataset of 306,070 German patents (1877-1918) from 9,562 archival image scans using our LLM-based pipeline powered by Gemini-2.5-Pro and Gemini-2.5-Flash-Lite. Our benchmarking exercise provides tentative evidence that multimodal...

Transitioning to a sustainable economy and reducing air pollution hinge on appropriate economic incentives and financing conditions. The auto loan market offers a prime setting, as lenders' credit terms can either discourage or incentivize the purchase of high-pollution vehicles. Using...
