Understanding the behavior of users online is important for researchers, policymakers, and private companies alike. But observing online behavior and conducting experiments is difficult without direct access to the user base and software of technology companies. We introduce Webmunk, an...

Studies of intermediated arbitrage argue that bank balance sheets are an important consideration, yet little evidence exists on banks' positioning in this context. Using confidential supervisory data (covering $25 trillion in daily notional exposures) we examine banks' positions in connection...

When labour market competition is imperfect, positive industry (and firm) productivity shocks can be passed through to workers in the form of higher wages. We document how the UK auto industry, following a period of decline, experienced a four-decade-long productivity boom. There was a...

While the importance of innovation to economic development is widely understood, the conditions conducive to it remain the focus of much attention. This volume offers new theoretical and empirical contributions to fundamental questions relating to the economics of innovation and technological...

We explore the economic effects of biodiversity loss by developing an ecologically-founded model that captures how different species interact to deliver the ecosystem services that complement other factors of economic production. Aggregate ecosystem services are produced by combining several...

Despite worldwide expansion of higher education, the impact of higher education institutions on local economic activity is still poorly understood. We analyze the local economic effects of branch campus openings in Tennessee and Texas, two states representative of the underlying U.S. enrollment...

We examine racial discrimination in the New Deal by examining access to work relief. The Federal Government prohibited racial discrimination in work relief programs. However, eligibility was determined by local and state administrators. We estimate Black-white gaps in work relief access...

Key methodologies used for managing weather risks have relied on the assumption that climate is not changing and that the historic weather record is therefore representative of current risks. Anthropogenic climate change upends this assumption, effectively reducing the information available to...

How prevalent are severe software vulnerabilities, how fast do software users respond to the availability of secure versions, and what determines the variance in the installation distribution? Using the largest dataset ever assembled on user updates, tracking server software updates by over...

When AI prediction substantially resolves trial uncertainty, a party purchasing AI prediction will disclose it if it is in their favour and not otherwise, signalling the outcome to the other party. Thus, the trial outcome becomes common knowledge. However, this implies that the parties will...
