Results • Agency costs shocks propagated through lender-project relationships
Results • Agency costs shocks propagated through lender-project relationships • Household responses amplify propagation
Results • Agency costs shocks propagated through lender-project relationships • Household responses amplify propagation • Propagation is greater when shocks are more persistent
Results • Agency costs shocks propagated through lender-project relationships • Household responses amplify propagation • Propagation is greater when shocks are more persistent • Asset market feedbacks shocks propagate across sectors
Broader contribution: New approach to modeling saving and investment
Broader contribution: • New approach to modeling saving and investment • Traditional model: Capital = accumulated output
Broader contribution: • New approach to modeling saving and investment • Traditional model: Capital = accumulated output • Lender expertise model: Capital = accumulated managerial knowledge
Model • Unit mass of households • Unit mass of specialized lenders • Periods t = 1,2,3,…
Model • Unit mass of households • Unit mass of specialized lenders • Periods t = 1,2,3,… • In each period, a lender is either matched with a project or searching for a new project
