Search Externalities in Firm-to-Firm Trade
Description: I develop a model of firm-to-firm search and matching to show that the impact of falling trade costs on firm sourcing decisions and consumer welfare depends on the relative size of search externalities in domestic and international markets. These externalities can be positive if firms share information about potential matches, or negative if the market is congested. Using unique firm-to-firm transaction-level data from Uganda, I document empirical evidence consistent with positive externalities in international markets and negative externalities in domestic markets. I then build a dynamic quantitative version of the model and show that, in Uganda, a 25% reduction in trade costs led to a 3.7% increase in consumer welfare, 12% of which was due to search externalities.

Digital Financial Inclusion in Emerging and Developing Economies: A New Index
Description: Adoption of technology in the financial services industry (i.e. fintech) has been accelerating in recent years. To systematically and comprehensively assess the extent and progress over time in financial inclusion enabled by technology, we develop a novel digital financial inclusion index. This index is based on payments data covering 52 developing countries for 2014 and 2017, taking into account both access and usage dimentions of digital financial services (DFSs). This index is then combined with the traditional measures of financial inclusion in the literature and aggregated into an overall index of financial inlusion. There are two key findings: first, the adoption of fintech has been a key driver of financial inclusion. Second, there is wide variation across countries and regions, with the greatest progress recorded in Africa and Asia and the Pacific regions. This index should offer a useful analytical tool for researchers and policy makers.

Firms’ Environmental Performance and the COVID-19 Crisis
Description: The shutdown in economic activity due to the coronavirus disease (COVID-19) crisis has resulted in a short-term decline in global carbon emissions, but the long-term impact of the pandemic on the transition to a low-carbon economy is uncertain. Looking at previous episodes of financial and economic stress to draw implications for the current crisis, we find that tighter financial constraints and adverse economic conditions are generally detrimental to firms’ environmental performance, reducing green investments. The COVID-19 crisis could thus potentially slow down the transition to a low-carbon economy. In light of the urgent need to reduce global greenhouse gas emissions, these findings underline the importance of climate policies and green recovery packages to boost green investment and support the energy transition. Policies that support the sustainable finance sector, such as improved transparency and standardization, could further help mobilize green investments.

The Impact of International Migration on Inclusive Growth: A Review
Description: International migration is an important channel of material improvement for individuals and their offspring. The movement of people across country borders, especially from less developed to richer countries, has a substantial impact in several dimensions. First, it affects the migrants themselves by allowing them to achieve higher income as a result of their higher productivity in the destination country. It also increases the expected income for their offspring. Second, it affects the destination country through the impact on labor markets, productivity, innovation, demographic structure, fiscal balance, and criminality. Third, it can have a significant impact on the countries of origin. It may lead to loss of human capital, but it also creates a flow of remittances and increases international connections in the form of trade, FDI, and technological transfers. This paper surveys our understanding of how migration affects growth and inequality through the impact on migrants themselves as well as on the destination and origin countries.

Corporate Funding and the COVID-19 Crisis
Description: This paper assesses whether corporate liquidity needs in the G7 economies were met during the containment phase of the COVID-19 pandemic (February-June 2020) using various approaches to identify credit supply shocks. The pandemic crisis adversely affected nonfinancial corporate sector cash flows, generating liquidity and solvency pressures. However, corporate borrowing surged in March and into the second quarter, thanks to credit line drawdowns and unprecedented policy support. In the United States, the bond market was buoyant from the end of March onward, but credit supply conditions for bank loans and the syndicated loan market tightened. In other G7 economies, credit supply conditions generally eased somewhat across markets during the second quarter. Among listed firms, entities with weaker liquidity or solvency positions before the onset of COVID-19, as well as smaller firms, suffered relatively more financial stress in some economies in the early stages of the crisis. Residual signs of strain remained as of the end of June. Policy interventions, especially those directly targeting the corporate sector, had a beneficial effect on credit supply overall.

Does a Wealth Tax Improve Equality of Opportunity? Evidence from Norway
Description: Does parental wealth inequality impact next generation labor income inequality? And does a tax on parental wealth affect the labor income distribution of the next generation? We tackle both questions empirically using detailed intergenerational data from Norway, focusing on effects on wages rather than capital income. Results suggest that a net wealth of NOK 1 million increases wages of the children by NOK 14,000. Children of wealthy parents also have a higher labor income mobility. The estimated hypothetical wage distribution without the wealth tax is more unequal. Moreover, suggestive evidence indicates parental wealth is associated with higher labor risk taking.

Equilibrium Foreign Currency Mortgages
Description: This paper proposes a novel explanation for why foreign currency denominated loans to households have become so popular in some emerging economies. Our argument is based on what we call the debt limit channel, which arises when multi-period contracts are offered to financially constrained borrowers against collateral that is established on newly acquired assets. Whenever the difference between domestic and foreign interest rates is positive, this effect biases borrowers’ choices towards foreign currency, even if the exchange rate is known to depreciate as implied by the interest parity condition. We demonstrate in a structural macroeconomic framework that the debt limit channel is quantitatively important and can result in dollarization of debt also in the presence of realistic exchange rate risk. Comparing this outcome to allocations under constrained-optimal time-consistent policy reveals that a substantial part of the identified bias towards foreign currency is due to a pecuniary externality, i.e. borrowers’ failure to internalize how their currency choice affects collateral prices.

Public Expenditure and Inclusive Growth - A Survey
Description: This paper explores the role of public expenditure in fostering inclusive growth. It starts with a presentation of salient features of public expenditure. Then, it lays out an analytical framework that describes the channels through which public expenditure affects inequality and poverty in the short and long term. Based on a review of the empirical literature, it discusses the policy options. Finally, the paper assesses the role of key factors such as the initial conditions, and the institutions, in shaping the inclusive spending policies.

Macroeconomic Stability and Inclusive Growth
Description: We survey the literature on the relationship between macroeconomic stability and inclusive growth and identify gaps in our knowledge. We examine the role of macroeconomic policies (fiscal, monetary, macroprudential, and exchange rate) and measures of inclusiveness (income inequality, consumption inequality, wealth inequality, poverty, and unemployment) across countries at different income levels. Avoiding procyclical macroeconomic policies and mitigating macroeconomic volatility should be on the agenda of all policymakers concerned with promoting inclusive growth. The emerging theory and evidence suggest a strong role for macroeconomic policies in shaping inclusive growth, both in the short-run and the long-run. The two-way relationship between the macroeconomy and inequality underscores the challenge of identifying and estimating causal relationships. Models with heterogeneous agents have much to offer in this area.

Competition, Innovation, and Inclusive Growth
Description: We provide an overview of the theories and empricial evidence on the complex relationship among innovation, competition, and inclusive growth. Competition and innovation-led growth are critical to drive productivity gains and support broad-based growth. However, new technologies and trends in market concentration are stifling future innovation while contributing to the marked increase in inequality. Beyond consumer welfare in a narrow market, competition policy should adapt to this new reality by considering the spillover and dynamic effects of market power, especially on firm entry, innovation, and inequality. Innovation policies should tackle not only government failures but also market failures.
