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...

We show that domestic production networks shape worker flows between firms. Data on the universe of firm-to-firm transactions for the Dominican Republic, matched with employer-employee records, reveals that about 20 percent of workers who change firms move to a buyer or supplier of their...

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...

This paper analyses the nature of the increasing regionalization process in global banking. Despite the large decline in aggregate cross-border banking lending volumes, some parts of the global banking network are currently more interlinked regionally than before the Global Financial Crisis....

Post-crisis dynamics show a shrinkage in the overall amount of crossborder bank lending,which has been interpreted in the literature as a retreat in financial globalization. In this paper, we argue that aggregate figures are not sufficient to support such a claim in terms ofthe overall structure...

We quantify the macroeconomic effects of COVID-19 for a small open economy by calibrating a SIR-multi-sector-macro model. We measure sectoral supply shocks utilizing teleworking and physical job proximity, and demand shocks with credit card purchases. Both shocks are also affected from changing...

This paper computes data-driven correlation networks based on the stock returns of international banks and conducts a comprehensive analysis of their topological properties. We first apply spatial-dependence methods to filter the effects of strong common factors and a thresholding procedure to...

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...

This paper studies the interconnectedness of the global financial system and its susceptibilityto shocks. A novel multilayer network framework is applied to link debt and equityexposures across countries. Use of this approach-that examines simultaneously multiplechannels of transmission and...

This paper studies changes in the transmission of common versus sectoral idiosyncraticshocks across different U.S. nonfarm business sectors during the Great Recession, andevaluates the cross-sectoral spillovers. Shocks are identified by dynamic factor methods. Wefind that the Great Recession is...
