While planes were grounded, capital flew out of emerging market economies in response to the acceleration in the spread of the virus in the early stages of the Covid-19 pandemic. Was this capital flight predictable once you account for the sudden deterioration in the global financial environment? In this post we present a model that helps to think about how financial conditions and international capital flows are linked. We then apply this methodology to events observed between March and May 2020, and find that the model predicted a large increase in the likelihood of capital flight. However, the scale of outflows was abnormally large even once the sharp tightening in financial conditions is accounted for.
The SIR model, first developed by Kermack and McKendrick (1927), remains the canonical epidemiological model. It a natural choice for economists seeking to model the interplay between economic and epidemiological dynamics. This briefing surveys some of the many adaptations to the basic SIR setup which have emerged in the epi-macro literature over the past six months. These have all been used to analyse issues such as lockdown policies, super-spreaders, herd immunity, hospital capacity and ‘test- and-trace’.
The Covid shock has created substantial and unprecedented challenges for monetary policymakers. This post summarises the key literature on the immediate monetary policy response to the shock, including both tools and short to medium-term strategy issues (but leaving aside the longer-term question of fiscal-monetary interactions).
The Coronavirus pandemic and measures to contain contagion had far reaching consequences on economic activities, which also led to a sharp fall in CO2 emissions. This has sparked new debate about how the recovery from the crisis could be made compatible with the Paris climate goals. In this post, I survey the emerging literature on the link between the economic recovery from the aftermath of the pandemic and climate change.

Since Covid-19-related crashes in March, major stock indices around the world have bounced back. This is despite little or no recovery in corporate earnings expectations. As a result, forward-looking price-to-earnings ratios have increased, rising above long-run average values in most large advanced economies and approaching record highs in the United States. Commenting on such valuations, some market participants have suggested there is ‘a great deal of optimism priced into the market’ and that stock prices ‘cannot defy economic gravity indefinitely’. This post takes a closer look at stock valuations, focusing on the UK, and drawing both on a textbook model and new research from academia.
During the current pandemic, economic variables have moved quickly and by large magnitudes. Given the publication lags for official data this has led to a greater emphasis on higher-frequency and/or more timely measures to track the economic impact of the pandemic and gauge the state of the economy in real time. This post looks at the emerging body of work in this area, with a particular focus on real-time measures of consumer expenditure and activity in the labour market.
The COVID-19 pandemic has rapidly spawned a literature analysing its impact on macroeconomic aggregates. But there’s also been work that seeks to look at heterogeneity of impacts across industries, households and individuals. This post summarises this literature which seeks to better understand the heterogeneous effects of the pandemic and associated policy responses on income, hours worked and employment status.
Have post-crisis reforms of banking regulation made banks and lending more resilient to the shock from Covid-19 and if so by how much? This blog takes one specific example – countercyclical capital buffers (CCyBs) – and shows that policy makers in a range of countries were able to quickly release these capital requirements, enabling banks to use the cumulated buffers. This released capital may in turn potentially help banks to support lending. And it will likely benefit lending in the country releasing requirements on buffers as well as banks’ lending to other countries, leading to potential positive international spillovers (see e.g. discussion of spillovers due to macroprudential policies by the ECB and others).

The Covid-19 crisis has led to a swift shift in the emphasis of macroeconomic research. At the centre of this is a new field of inquiry called ‘epi-macro’ that combines epidemiological models with macroeconomic models. In this post, we give a brief introduction to some of the earliest papers in this fast-growing literature.
