We study how the optimal degree of conservatism relates to decision-making procedures in a Monetary Policy Committee (MPC). In our framework, central bank conservatism is required to attenuate the volatility of monetary decisions generated by the presence of uncertainty about the committee...

Consumers are very responsive to sales, yet statistical agency practice typically under-weights sale prices in the Consumer Price Index (CPI). Evidence is lacking on the impact on the representativeness of prices included in the CPI and on estimates of inflation. We use high-frequency scanner...

Kenya is about to embark on an important reform to expand banking to millions of poor households by enabling third-party retail agents as a low-cost distribution alternative to branches. However, this initiative risks being undermined by the mobile network operator (MNO) Safaricom, which...

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...

We quantify the impact that central bank refinancing o perations a nd f unding f acilities had at reducing the banking sector's intrinsic fragility in the euro area in 2014-2019. We do so by constructing, estimating and calibrating a micro-structural model of imperfect competition in the banking...

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...
