This lecture argues that the Global Financial Cycle is a challenge for the validity of the Mundellian trilemma. I present evidence that US monetary policy shocks are transmitted internationally and affect financial conditions even in inflation targeting economies with large financial markets....

We review the literature on the empirical characteristics of the global financial cycle and associated stylized facts on international capital flows, asset prices, risk aversion and liquidity in the financial system. We analyse the co-movements of global factors in asset prices and capital flows...

We construct novel text-based measures of firm-level cyber risk exposure based on quarterly earnings calls of 12,000+ firms from 85 countries over 20+ years. We categorize each cyber-related discussion into topics that capture sentiment, monetary loss, country names, etc. We document new facts...

Before the 2008 crisis, the cross-sectional skewness of banks' leverage went up and macro risk concentrated in the balance sheets of large banks. Using a model of profit-maximizing banks with heterogeneous Value-at-Risk constraints, we extract the distribution of banks' risk-taking parameters...

International currencies fulfill different roles in the world economy with important synergies across those roles. We explore the implications of currency hegemony for the external balance sheet of the United States, the process of international adjustment, and the predictability of the US...

What is the impact of granular credit risk on banks and on the economy? We provide the first causal identification of single-name counterparty exposure risk in bank portfolios by applying a new empirical approach on an administrative matched bank-firm dataset from Norway. Exploiting the fat tail...

Financial crises cause economic, social and political havoc. Macroprudential policies are gaining traction but are still severely under-researched compared to monetary policy and fiscal policy. We use the general framework of sequential predictions also called online machine learning to forecast...

We use a unique dataset on television prices across European countries and regions to investigate the sources of differences in price levels. Our findings are as follows: (i) Quality is a crucial determinant of price differences. Even in an integrated economic zone as Europe, rich economies tend...

Cross border capital flows and returns on assets are two key variables in international macroeconomics. Difficult endogeneity issues plague any analysis of their correlations in aggregate data. This paper examines the dynamics of international portfolios with a unique data set on the stock...

This article summarizes our views on the role of an "aggregation bias" in explaining the PPP Puzzle, in response to the several papers recently written in reaction to our initial contribution. We discuss in particular the criticisms of Imbs, Mumtaz, Ravn and Rey (2002) presented in Chen and...
