How Does the Repo Market Behave Under Stress? Evidence From the COVID-19 Crisis
Description: We examine how the repo market operates during liquidity stress by applying network analysis to novel transaction-level data of the overnight gilt repo market including the COVID-19 crisis. During this crisis, the repo network becomes more connected, with most institutions relying on existing trade relationships to transact. There are however significant changes in the repo volumes and spreads during the stress relative to normal times. We find a significant increase in volumes traded in the cleared segment of the market. This reflects a preference for dealers and banks to transact in the cleared rather than the bilateral segment. Funding decreases towards non-banks, only increasing for hedge funds. Further, spreads are higher when dealers and banks lend to rather than borrow from non-banks. Our results can inform the policy debate around the behaviour of banks and non-banks in recent liquidity stress and on widening participation in CCPs by nonbanks.

The COVID-19 Impact on Corporate Leverage and Financial Fragility
Description: We study the impact of the COVID-19 recession on capital structure of publicly listed U.S. firms. Our estimates suggest leverage (Net Debt/Asset) decreased by 5.3 percentage points from the pre-shock mean of 19.6 percent, while debt maturity increased moderately. This de-leveraging effect is stronger for firms exposed to significant rollover risk, while firms whose businesses were most vulnerable to social distancing did not reduce leverage. We rationalize our evidence through a structural model of firm value that shows lower expected growth rate and higher volatility of cash flows following COVID-19 reduced optimal levels of corporate leverage. Model-implied optimal leverage indicates firms which did not de-lever became over-leveraged. We find default probability deteriorates most in large, over-leveraged firms and those that were stressed pre-COVID. Additional stress tests predict value of these firms will be less than one standard deviation away from default if cash flows decline by 20 percent.

Barriers to Trade in Financial and Insurance Services: Evidence from the United Kingdom
Description: Distance, as a proxy for trade barriers, is found in many studies to matter even for weightless cross-border financial investments and lending, possibly due to the presence of information asymmetries. Its importance is tested in this paper using exports of all five broad categories of the U.K.’s financial and insurance services. No trade barriers are found for the bulk of the U.K.’s exports. Trade barriers are confirmed only for interest-bearing activities – being in line with available results in the literature. The positive effect of EU membership appears to be small. Notwithstanding the uncertainties, it suggests that post-Brexit disruptions of the U.K.’s export of financial and insurance services may be minor.

Monitoring the Climate Impact of Fiscal Policy - Lessons from Tracking the COVID-19 Response
Description: In the wake of the COVID-19 crisis, governments around the world announced unprecedented fiscal packages to address the economic impact of the crisis. The unusually large scale of the packages was accompanied by widespread calls for “greening” them to meet the dual goals of economic recovery and environmental sustainability. In response, several researchers and international organizations attempted to assess the “greenness” of the fiscal policy response of the world’s largest economies. This paper takes stock of the contributions made by these various trackers, identifies strengths and weaknesses of their methodologies, and draws lessons for assessing the climate impact of fiscal policy going forward. It finds that: trackers provided useful assessments of the (generally low) level of greenness and raised awareness; trackers’ methodologies, while valid and innovative, varied significantly with some important, if currently largely unavoidable, weaknesses; and the way forward should involve tracking the greenness of entire government budgets, rather than just their response to the COVID-19 crisis.

Knowledge Spillovers From Superstar Tech-Firms: The Case of Nokia
Description: Do workers hired from superstar tech-firms contribute to better firm performance? To address this question, we analyze the effects of tacit knowledge spillovers from Nokia in the context of a quasi-natural experiment in Finland, the closure of Nokia’s mobile device division in 2014 and the massive labor movement it implied. We apply a two-stage difference-in-differences approach with heterogeneous treatment to estimate the causal effects of hiring former Nokia employees. Our results provide new evidence supporting the positive causal role of former Nokia workers on firm performance. The evidence of the positive spillovers on firms is particularly strong in terms of employment and value added.

Household Deleveraging and Saving Rates: A Cross-Country Analysis
Description: Historically high household debt in several economies is calling for a deleveraging, but according to some economists, this adjustment can slow GDP growth by weighing on consumption. Using a sample of advanced and emerging market economies, this paper finds evidence of a negative relationship between changes of household debt-to-income ratios and saving rates. This relationship is however asymmetric, being significant only for debt build-ups. Declining debt ratios and saving are significantly related in some economies, but the relationship is driven by consumer credit, not by mortgages. Results therefore suggest that the economic cost associated with household deleveraging may be overestimated and motivate a deleveraging via lower mortgages.

A Balance-Sheet Analysis of the Dutch Economy
Description: The Dutch economy is characterized by substantial financial balance sheets in the private sector. Uncommonly large gross financial assets and liabilities are found in the financial sector, whereas households own significant net financial wealth. The large gross financial assets and liabilities reflect a dominant role of multinational corporations (MNCs). Despite their size, these financial positions have not brought significant financial stability risks to the country. On the other hand, Dutch households’ long balance sheets have been associated with depressed consumption and volatile real estate investment, which has probably exacerbated the cyclicality of the economy. The expected reform of the pension system is likely to change the way household balance sheets interact with private consumption.

Safe Asset Demand, Global Capital Flows and Wealth Concentration
Description: The US economy is often referred to as the “banker to the world,” due to its unique role in supplying global reserve assets and funding foreign risky investment. This paper develops a general equilibrium model to analyze and quantify the contribution of this role to rising wealth concentration among American households. I highlight the following points: 1) financial globalization raises wealth inequality in a financially-developed economy initially due to foreign capital pressing up domestic asset prices; 2) much of this increase is transitory and can be reversed as future expected returns on domestic assets fall; and 3) despite the low-interest-rate environment, newly accessed foreign capital provides incentives for affluent households to reallocate wealth toward risky assets while impoverished households increase their debt. Wealth concentration ensues only if this rebalancing effect is large enough to counteract diminished return on domestic assets. Quantitative analysis suggests that global financial integration alone can account for a third to a half of the observed increase in the current top one percent wealth share in the US, but indicates a possible reversal in the future.

Analyzing Capital Flow Drivers Using the ‘At-Risk’ Framework: South Africa’s Case
Description: Cross-border capital flows are important for South Africa. They fund the nation’s relatively large external financing needs and have important financial stability implications evidenced by the large capital outflows and asset price selloffs during the COVID-19 pandemic. This paper adds to the literature on the drivers of South Africa’s capital flows by applying the ‘at-risk’ framework––which differentiates between the likelihood of “extreme” inflows (surges) and outflows (reversals) and of “typical” flows––to both nonresident and resident capital flows. Estimated results show that among nonresident flows, the portfolio debt component is most sensitive to changes in external risk sentiment particularly during reversals. This applies to flows to the sovereign sector. Nonresident equity flows, both portfolio and FDI, are most sensitive to domestic economic activity especially during surges. This applies to flows to the corporate and banking sectors. Results also suggest that resident flows, in particular the FDI component, tend to offset nonresident flows, thus acting as buffers against funding withdrawal during periods of global risk aversion.

Measuring the Redistributive Capacity of Tax Policies
Description: This paper presents a novel technique to measure and compare the redistributive capacity of observed tax (or transfer) policies. The technique is based on income distribution simulations and controls for differences in pre-tax income distributions. It assumes that the only information on the pre-tax distribution available in each country-year is the Gini coefficient and the mean (GDP per capita). We illustrate the technique with an application to the personal income tax, using a dataset of 108 countries over the 2007-2018 period.
