We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call "globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus being able to overcome what would otherwise be a fast saturation...

"Closing borders is naive, the virus will come regardless" - this was the policy assumption that was repeatedly stated until mid-March by the WHO, the EU, as well as responsible authorities in Germany and other countries. Meanwhile, other states had started closing their borders to travellers...

We study the evolution of interest about climate change between different actors of the population, and how the interest of those actors affect one another. We first document the evolution individually, and then provide a model of cross influences between them, that we then estimate with a VAR....

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...

Developing research methodology contributes to better management research outputs, links better management theory to business practice, as well as enriches the academic training received by the students at universities. Researchers might be tempted to provide generalizations on management...

What is the role of international migrants and, specifically, migrant networks in shaping political attitudes and behavior in migrant sending countries? Our theoretical framework proposes that migration might change individual social identities and thus stimulate intrinsic motivation for...

We study optimal monetary policy in an environment in which firms' pricing and production decisions are subject to informational frictions. Our framework accommodates multiple formalizations of these frictions, including dispersed private information, sticky information, and certain forms of...

This paper explains why crises follow periods of sustained banking profitability in an environment in which there is uncertainty about whether outcomes depend on the risk management skills of banks, or are just based on luck, in the spirit of Piketty's Model (1995) of “left-wing” and...

The study examines the predictability of 48 sovereign bond markets based on a strategy of 27,000 technical trading rules. These rules represent four popular trading rule classes, they are: moving average, filtering, support and resistance, and channel breakout rules, with numerous variants in...

Wealthier economies experience less frequent but more severe financial crises. To investigate this puzzle, we propose a model of collateralized lending in which: (1) borrowers endogenously determine collateral quality, and (2) lenders can produce costly information about collateral. In...
