It takes many years for more efficient electronic payments to be widely used, and the fees thatmerchants (consumers) pay for using those services are increasing (decreasing) over time. Weaddress these puzzles by studying payments system evolution with a dynamic model in a twosidedmarket setting....

Financial risks outside of the traditional banking sector can quickly spread throughout financial systems and lead to disruptions in the real economy. A lack of adequately detailed financial sector statistics can obscure buildups of risks from policymakers and hinder their ability to effectively...

Many central banks have relied on a range of policy tools, including foreign exchange intervention (FXI) and capital flow management tools (CFMs), to mitigate the effects of volatile capital flows on their economies. We develop an empirically-oriented New Keynesian model to evaluate and quantify...

We extend the New Keynesian (NK) model to include endogenous risk. Lower interest rates not only shift consumption intertemporally but also conditional output risk via their impact on risk-taking, giving rise to a vulnerability channel of monetary policy. The model fits the conditional output...

The USD asset share of non-U.S. banks captures the demand for dollars by these investors. An instrumental variable strategy identifies a causal link from the USD asset share to the USD exchange rate. Cross-sectional asset pricing tests show that the USD asset share is a highly significant...

Using panel quantile regressions for 11 advanced and 10 emerging market economies, weshow that the conditional distribution of GDP growth depends on financial conditions, withgrowth-at-risk (GaR)-defined as growth at the lower 5th percentile-more responsive thanthe median or upper percentiles....

We measure the gains from phasing out coal as the social cost of carbon times the quantity of avoided emissions. By comparing the present value of the benefits from avoided emissions against the present value of costs of ending coal plus the costs of replacing it with renewable energy, our...

This paper jointly analyzes the optimal conduct of monetary policy, foreign exchange intervention, fiscal policy, macroprudential policy, and capital flow management. This policy analysis is based on an estimated medium-scale dynamic stochastic general equilibrium (DSGE) model of the world...

We develop a microfounded New Keynesian model to analyze monetary policy and financial stability issues in open economies with financial fragilities and weakly anchored inflation expectations. We show that foreign exchange intervention (FXI) and capital flow management tools (CFMs) can improve...

The global financial system has shown remarkable resilience during the COVID-19 pandemic, despite a sharp decline in economic activity and the initial financial market upheaval in March 2020. This paper takes stock of the factors that contributed to this resilience, focusing on the role of...
