We propose a simple macroeconomic model with input-output sectoral linkages based on Acemoglu et al. (2016) to quantify how changes in aggregate demand due to additional income from household's remittances propagates through the network of input-output linkages in Sub-Saharan African countries....

This paper presents a novel approach to investigate and model the network of euro area banks' large exposures within the global banking system. Drawing on a unique dataset, the paper documents the degree of interconnectedness and systemic risk of the euro area banking system based on bilateral...

This paper assesses whether cross-border M&A decisions exhibit network effects. We estimate exponential random graph models (ERGM) and temporal exponential random graph models (TERGM) to evaluate the determinants of cross-country M&A investments at the sectoral level. The results show that...

This paper studies banks' decision to form financial interconnections using a model of financial contagion that explicitly takes into account the crisis state of the world. This allows us to model the network formation decision as optimising behaviour of competitive banks, where they balance the...

Anecdotal evidence suggests the existence of specific choke points in the global trade network revealed especially after natural disasters (e.g. hard drive components and Thailand flooding, Japanese auto components post-Fukushima, etc.). Using a highly disaggregated international trade database...

The paper applies a network analysis framework to analyze the regional and global integration of Latin American and Caribbean (LAC) countries. We compare network-based measures of trade integration to conventional measures, decomposing integration along several dimensions to better understand...

We study the determinants of new and repeated research collaborations, drawing on the co-authorship network of the International Monetary Fund (IMF)'s Working Papers series. Being an outlet where authors express their views on topics of interest, and given that IMF staff is not subject to the...

The application of Deep Reinforcement Learning (DRL) in economics has been an area of active research in recent years. A number of recent works have shown how deep reinforcement learning can be used to study a variety of economic problems, including optimal policy-making, game theory, and...

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...

Recent literature has shown that corporate indebtedness affects firm-level investment behavior but not necessarily aggregate business cycles. I argue that interactions among heterogeneous firms play an important role in equilibrium. After a downturn, financially unconstrained firms in...
