We develop a New Keynesian model where all payments between agents require bank deposits, bank deposits are created through disbursement of bank loans, and banks face convex lending costs. At the zero lower bound on deposit rates (ZLBD), changes in policy rates affect activity through both real...

This paper studies optimal policy in a stylised New Keynesian model that is extended to incorporate imperfect substitutability between short-term and long-term bonds. This simple modification provides a channel through which asset purchases by the policymaker can affect aggregate demand. Because...

Motivated by policies implemented by some central banks in response to the financial crisis, we use a simple New Keynesian model to study a particular form of forward guidance. We assume that the policy maker makes a state-contingent commitment to hold the policy rate at the zero lower bound...

We show that interest rate rules that feed back on the growth rates of target variables (such as output or asset prices) may induce recessions in the presence of a zero lower bound, through purely self-fulfilling dynamics. This pathology is illustrated in a small New Keynesian model with...

We characterise the large number of mortgage offers for which people qualify. Almost no one picks the cheapest option, nonetheless the one selected is not usually much more expensive. A few borrowers make very expensive choices. These big mistakes are most common when the menu they face has many...

We exploit a unique dataset that features both un-intermediated mortgage requests and independent responses from multiple banks to each request. We show that households typically are not prudent risk managers, but prioritize minimizing current mortgage payments over insurance against future rate...

We develop a two-sector DSGE model with a detailed banking sector along the lines of Clerc et al (2015) to assess the impact of macroprudential tools (minimum, countercyclical and sectoral capital requirements, as well as a loan-to-value limit) on key macroeconomic and financial variables. The...

How does bank profitability vary with interest rates? We present a model of a monopolistically competitive bank subject to repricing frictions, and test the model's predictions using a unique panel data set on UK banks. We find evidence that large banks retain a residual exposure to interest...

This paper estimates the intraday value of money implicit in the UK unsecured overnight money market. Using transactions data on overnight loans advanced through the UK large-value payments system (CHAPS) in 2003-09, we find a positive and economically significant intraday interest rate. While...
