This paper examines the relationship between location, liquidity, and prices in housing markets. We construct spatial datasets for German and U.S. cities and show that liquidity and prices decline with distance to the city center. To rationalize these results, we build a structural model with...

New importers increase their conditional survival rate and import share over time. However, a model of multi-input firms with an import entry cost and stochastic import costs cannot replicate these dynamics. I show that an extended model can be reconciled with the data. I calibrate both models...

Carbon dioxide removal (CDR) is considered essential for climate change mitigation, yet its optimal role in climate policy remains unclear in the presence of non-permanent storage, en-ergy constraints, and fossil fuel scarcity. We integrate CDR into an analytic integrated assess-ment model to...

This paper highlights an underexplored margin of heterogeneity that shapes resilience to disruptions in global shipping - the differential reliance of countries and sectors on specific categories of vessels. We combine US bills of lading records with ship registry and AIS-based port call data to...

Climate change damages vary across countries, because of regional variation in climate metrics like temperature and regional variation in economic exposure. This is evident in the breakdown of the social cost of carbon: the country social cost of carbon (CSCC). While for the former a large...

We show that plurilateral agreements facilitate global tariff liberalization by creating an MFN-based margin of cooperation that leaves preferential access via preferential trade agreements (PTAs) unchanged. In a model of endogenous trade agreement formation with farsighted governments, PTAs...

Research and development (R&D) is a central driver of long-term economic growth, technological progress, and institutional capacity. Yet many African countries remain marginal in the global knowledge economy, with limited investment in science, technology, and innovation (STI) and weak research...

This paper provides a comprehensive overview of China’s lending to developing countries - a central feature of today’s international financial system. Building on our previous research and the work of others, we document the scale, destination, and terms of China’s overseas lending boom,...

We review the literature on the political economy of foreign aid, examining the geopolitical returns generated by Official Development Assistance (ODA). Our paper identifies conditions under which donors are able to influence political and economic outcomes in recipient countries, shape their...

Development aid faces a crisis of budgets, legitimacy, and political alignment. Framed in recent decades as technocratic and benevolent, aid has always been political, shaped by donor and recipient incentives. Its post–Cold War expansion reflected a permissive era of unipolarity and...
