We study a dynamic stochastic general equilibrium model in which agents are concerned about model uncertainty regarding … from climate change to damages is subject to uncertainty, as opposed to risk, and we use robust control to study efficiency … growth in the presence and in the absence of concerns about model uncertainty, and find that these can lead to substantially …

We specify and estimate a dynamic game to study the equilibrium relationship between market structure and innovation in … as stochastically increasing in innovation, the dynamic control, which is proxied by patent applications. Equilibrium … innovation is a function of market structure, the vector of quality levels of all active firms, and the cost of R&D. Our main …

Efficiency is estimated to be stochastically increasing in the dynamic control-innovation-which is proxied by patenting behavior …. Equilibrium innovation is a function of all state variables in the industry and the cost of R&D which includes a privately …
