We study how the interaction of market power and nominal price rigidity influences inflation dynamics. We formulate a tractable model of oligopolistic competition and sticky prices and derive closed-form expressions for the pass-through of idiosyncratic and common cost shocks to firms' prices....

Price-setting models with monopolistic competition and costs of changing prices exhibit coordination failure: in response to a monetary policy shock, individual agents lack incentives to change prices even when it would be Pareto-improving if all agents did so. The potential welfare gains are in...

This paper studies bank competition with borrower adverse selection. In the model, expected non-performing loan costs are high when credit is granted in booms, when risk free rates are low, or when competition is strong. I prove that full competition is suboptimal due to this last effect; that...

Recent experience from Europe and Japan shows that commercial banks generally pass negative short-term policy rates on to wholesale depositors, such as insurances and pension funds. Yet, they refrain from charging negative rates to ordinary retail customers. This paper asks whether the existing...

The emergence of a decentralized peer-to-peer platform that matches lending and borrowing without collateral requirements has called the bank lending and balance-sheet channels for monetary transmission into question. Via a standard New Keynesian macroeconomic model expanded with two-sided...

A new wave of technological innovations, often called 'fintech,' is accelerating change in the financial sector. What impact might fintech have on financial services, and how should regulation respond? This paper sets out an economic framework for thinking through the channels by which fintech...

Central bank digital currencies (CBDCs) promise many benefits but, if not well designed, they could have undesired consequences, including for monetary policy. Issuing an unremunerated CBDC or a wholesale CBDC does not change the objectives of monetary policy or the operational framework for...
