This paper proposes a quantitative theory of unsecured borrowing via credit cards. We explicitly model key features of credit cards: (i) they are pre-approved lines of credit, (ii) they are long-lasting relationships with endogenous duration. We endogenize duration by modeling explicit frictions...

What contributes to the growing income inequality across U.S. households? We develop an information- based general equilibrium model that links capital income derived from financial assets to a level of investor sophistication. Our model implies income inequality between sophisticated and...

This paper evaluates the performance of leading micro-founded pricing-to-market frictions vis-a-vis a set of robust stylized facts about international prices. In order to make that evaluation meaningful, we embed each friction into a unified IRBC framework and parameterize the models in a...

The article develops a new theory of pricing to market driven by dynamic frictions of building market shares. Our key innovation is a capital theoretic model of marketing in which relations with customers are valuable. We discipline the introduced friction using data on differences between...

This paper develops a new theory of pricing-to-market driven by sluggish market shares. Our key innovation is a capital theoretic model of marketing in which relations with the customers are valuable. We discipline the introduced friction using a unique prediction of the model about the low...

This paper develops a theory of pricing-to-market driven by marketing and bargaining frictions. Our key innovation is a capital theoretic model of marketing in which relations with customers are valuable. In our model, producers search and form long-lasting relations with their customers, and...
