In the wake of the global financial crisis in 2008, nominal interest rates in the US and other advanced economies have approached the effective lower bound (ELB). This fact has motivated new research to understand, both theoretically and empirically, the impact of monetary policies when the nominal policy rate is at the ELB. In a new paper, we show that accounting for balance sheet policies (QE) can ease the constraints imposed by the ELB on monetary policy and resolve several paradoxical results arising in canonical New Keynesian models at the ELB. The ‘paradox of flexibility’, the ‘paradox of toil’ and the puzzle of excessively large fiscal multipliers are all resolved when QE is added to the model as policy tool.
Better communications, enhanced transport links, integration agreements between governments, and other factors have all helped increase global economic interconnectedness over the past few decades. Yet, comparing a state-of-the-art gravity model for trade versus migration reveals important differences in the evolution of globalization over time on flows of goods versus people. For trade, the boost from free trade agreements declines the farther apart signatories are, but for migration the boost increases with distance between signatories. Further, while both border and distance frictions have declined for trade over time, this is not the case for migration flows.
Are less open economies more resilient to downturns? There is general agreement on the benefits of openness, but its adverse link to volatility is ambiguous. On the one hand, globalisation makes countries less sensitive to domestic disturbances, yet it also makes them more exposed to foreign shocks. In this post, I use local projections (LP) to show that international business cycles since 1870 appear to support a positive effect of openness on the economic resilience of a country, and that we may thus expect the current international slowbalisation trend to worsen future recessions.
How is household consumption affected by borrowing constraints in the mortgage market? In a new paper, we answer this question by studying the UK’s Help to Buy (HTB) program over the period 2014–16. The program facilitated home purchases with only a 5% down payment and resulted in a sharp relaxation of the down-payment constraint. We show that HTB boosted household consumption in addition to stimulating housing market activity. Home purchases increased by 11%, and the increase was driven almost entirely by first-time and young buyers. In addition, household consumption grew by 5% more in parts of the UK more exposed to the program. Relaxing the down payment constraint thus has important macroeconomic effects that extend beyond the housing market.

Text data is often raw and unstructured, and yet it is the key means of human communication. Textual analysis techniques are increasingly being used in economic and financial research in a variety of different ways. In this post we apply these techniques to a new setting: the text comments left by respondents to the Decision Maker Panel (DMP) Survey, a UK-wide monthly business survey. Using over 20,000 comments, we show that: (i) these comments are a rich and unexplored data source, (ii) Brexit has been the dominant topic of comments since 2016, (iii) text-based indices match existing uncertainty measures from the DMP at both the aggregate and firm level, and (iii) sentiment among UK firms has been declining since 2016.

Average tariffs on goods traded between the US and China increased by 15 percentage points from early 2018 to 2019. By making it more costly to buy goods from abroad, higher tariffs have reduced global trade flows and spending by households and businesses. But ‘direct’ effects of tariffs are not the only ways in which trade-related issues can affect global growth. Trade-related uncertainty has risen sharply since the escalation of trade tensions in 2018, which may have caused businesses to postpone costly investment decisions and financial conditions to tighten. In this post we investigate the size of these ‘indirect’ channels.

Understanding gross capital flows is crucial for both macroeconomic and financial stability policy. However, theory is lagging behind empirical work, as much of the literature continues to rely on net capital flow models developed many decades ago. Missing from these models is an explicit tracking of the financial records underlying all goods and asset purchases, namely gross balance sheet positions, which in turn requires modelling the principal medium of exchange, bank deposits. Our new model features gross capital flows and offers a fresh perspective on important policy debates, such as the role of current accounts as indicators of financial fragility, the nature of the global saving glut, Triffin’s current account dilemma, and the synchronisation of gross capital inflows and outflows.
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 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.
