We study how frictions in learning others' technology, termed "imperfect technology spillovers," impact firm innovation strategies and the aggregate economy through changes in innovation composition. We develop an endogenous growth model that generates strategic innovation decisions, where...

Livestock production is responsible for most of the greenhouse gas (GHG) emissions from European agriculture. To achieve the climate targets in the European Union, reducing emissions from the food chain, and within that from livestock production, is imperative. Along with structural changes,...
