This paper studies how information and communication technology (ICT) improvements affect trade along the value chain and international technology diffusion. We examine the impact of a revolutionary technology, the roll-out of the global telegraph network, on the 19th century cotton textile...

Sea-level rise and ensuing permanent coastal inundation will cause spatial shifts in population and economic activity over the next 200 years. Using a highly spatially disaggregated, dynamic model of the world economy that accounts for the dynamics of migration, trade, and innovation, this paper...

This paper quantitatively assesses the world's changing economic geography and sectoral specialization due to global warming. It proposes a two-sector dynamic spatial growth model that incorporates the relation between economic activity, carbon emissions, and temperature. The model is taken to...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

This paper examines the future of remote work by drawing parallels between two contexts: The move from home to factory-based production during the Industrial Revolution and the shift to work from home today. Both are characterized by a similar trade-off: the potential productivity advantage of...

We construct a novel plant-level dataset to examine the process of technology adoption during a period of rapid technological change: The diffusion of mechanized cotton spinning during the Industrial Revolution in France. We document new stylized facts that can help explain why major...

This chapter reviews the empirical economics literature on the impact of trade liberalization on firms' innovation-related outcomes. We define and examine four types of shocks to trade flows: import competition, export opportunities, access to imported intermediates, and foreign input...

We study how the technological importance of inputs – measured by cost shares – is related to the decision to “make” or “buy” that input. Using detailed French international trade data and an instrumental variable approach based on self-constructed input-output tables, we show that...

When managers have objectives beyond maximizing monetary profits, inefficiencies may arise. An increase in competition may then force managers to improve the productivity of the firm in order to ensure survival. While this hypothesis has received ample theoretical attention, empirical evidence...

In the US and many other OECD countries, expenditures for defense-related R&D represents a key policy channel through which governments shape innovation, and dwarf all other public subsidies for innovation. We examine the impact of government funding for R&D - and defense-related R&D in...
