We present a theory in which the key driver of short-term debt issued by the financial sector is the portfolio demand for safe and liquid assets by the nonfinancial sector. This demand drives a premium on safe and liquid assets that the financial sector exploits by owning risky and illiquid...

We examine financial intermediation when banks can offer deposit or loan contracts contingent on macroeconomic shocks. We show that the risk allocation is efficient if there is no workout of banking crises. In this case, banks will shift part of the risk to depositors. In contrast, under a...

We examine whether the economy can be insured against banking crises with deposit and loan contracts contingent on macroeconomic shocks. We study banking competition and show that the private sector insures the banking system through such contracts, and banking crises are avoided, provided that...

We examine banking competition when deposit or loan contracts contingent on macroeconomic shocks become feasible. We show that the risk allocation is efficient, provided that banks are not bailed out. In this case, banks may shift part of the risk to depositors. The private sector insures the...

The author studies the terms of credit in a competitive market in which sellers are willing to repeatedly finance the purchases of buyers by extending direct credit. Lenders (sellers) can commit to deliver any long-term credit contract that does not result in a payoff that is lower than that...

Banks' loan pricing decisions reflect the fact that borrowers tend to have long-lasting relationships with lenders. Therefore, pricing decisions have an inherently dynamic component: high interest rates may yield higher static profits per loan, but in the long run they erode a banks' customer...

I build a general equilibrium model of the transmission of monetary policy on bank lending. Bank lending is done by individual banks that face random investment opportunities by creating inside money. Banks are subject to a reserve requirement and have access to the interbank money market. The...

Through the euro area crisis, financial fragmentation across jurisdictions became a prime concern for the single monetary policy. The ECB broadened the scope of its instruments and enacted a series of non-standard measures to engineer an appropriate degree of policy accommodation. The...

I investigate the theoretical impact of central bank digital currency (CBDC) on a monopolistic banking sector. The framework combines the Diamond (1965) model of government debt with the Klein (1971) and Monti (1972) model of banking. There are two main results. First, the introduction of...

We analyze optimal monetary policy in a sticky pricemodel where the central bank supplies money outrightvia asset purchases and lends money temporarily againstcollateral. The terms of central bank lending affect ra-tioning of money and impact on macroeconomic aggre-gates. The central bank can...
