This paper is a theoretical study into how credit constraints interact with aggregate economic activity over the business cycle. We construct a model of a dynamic economy in which lenders cannot force borrowers to repay their debts unless the debts are secured. In such an economy, durable assets...

This paper describes how imperfect information in both capital and labor markets can, in a context of maximizing firms and perfectly flexible prices and wages, give rise to cyclical variations in unemployment whose character closely resembles that of observed business cycles

Standard economic theory says that unsecured, high-interest, short-term debt -- such as borrowing via credit cards and bank overdraft facilities -- helps individuals smooth consumption in the event of transitory income shocks. This paper shows that -- on average -- individuals do not use such...

This paper develops a network model of interbank lending, in which banks decide to extend credit to their potential borrowers. Borrowers are subject to shocks that may force them to default on their loans. In contrast to much of the previous literature on financial networks, we focus on how...

Research on leverage and asset-price fluctuations focuses on the direct effect of lax bank lending enabling financially-constrained investors to take excessive risks. Ignored are unconstrained investors speculating on higher prices during credit booms. To identify these two effects, we utilize...

The market for corporate credit is characterized by significant seasonal variation, both in interest rates and the volume of new lending. Firms borrowing from banks during seasonal "sales" in late spring and fall issue at 19 basis points cheaper than winter and summer borrowers. Issuers during...

The "equilibrium" bubble size depends on investor sentiment, however, and it typically does not coincide with the "optimal" bubble size. This provides a new rationale for macroprudential policy. A lender of last resort can replicate the "optimal" bubble by taxing credit when the "equilibrium"...

A growing literature shows that credit indicators forecast aggregate real outcomes. While researchers have proposed various explanations, the economic mechanism behind these results remains an open question. In this paper, we show that a simple, frictionless, model explains empirical findings...

This paper studies strategic decision making by a private currency ledger operator, which faces competition from public money and/or other ledgers. A monopoly ledger operator can incentivize contract enforcement across the financial sector by threatening exclusion, but it can also impose markups...
