This paper proposes a tractable way to incorporate lending standards ("credit qualification thresholds") into macro models of financial frictions. Banks can reject borrowers whose risk is above an endogenous threshold at which no lending rate sufficiently compensates banks for the borrowers'...

We analyze a model of mortgage markets, housing tenure choice, heterogeneous agents, and default with closed form solutions. We uncover new insights which may inspire empirical work, and we ground already-established insights in a series of tractable expressions. Then we study optimal LTV...

We propose a quantitative model of lending standards with two reasons for inefficient credit: lenders' moral hazard from deposit insurance or government guarantees, and imperfect information about the persistence of asset price growth, which generates incorrect but rational beliefs in the...
