Abstract: We solve a real business cycle model with rational inattention (an RI-RBC model). In the standard model, news about future productivity fails to cause business cycle comovement. In response to a positive news shock, consumption rises but employment and investment fall. Introducing rational inattention helps produce comovement. Agents choose an optimal signal about the state of the economy. The optimal signal turns out to confound current with expected future productivity. Labor and investment demand rise after a news shock, causing an output expansion. Rational inattention also improves the propagation of a standard productivity shock, by inducing persistence.
