In this paper, we study how the interbank market could impact deposit competition and bank profits. We first document two stylized facts: the net interbank funding ratio is negatively correlated with net interest margin (NIM), as well as with the cost-to-income ratio (CIR). To rationalize these...

Economic agents are typically connected in multiple interrelated networks (multiplex). We examine how an initial “seed” network prompts link formation on the multiplex and shapes its equilibrium topology. In a duplex, positive (negative) externalities emanating from strategic complementarity...

Outbreaks of infectious diseases bring behavior and policy responses into sharp focus since societies face acute constraints and uncertainties. This paper compares two infectious disease outbreaks: the Covid-19 pandemic and the 1665 London plague outbreak described by Daniel Defoe in A Journal...

The result that firms competing in a Cournot oligopoly with pairwise collaboration form a complete network under zero or negligible link formation costs provided by Goyal and Joshi (2003) no longer hold in multi-market oligopolies. Link formation in one market affects a firm’s profitability...

This paper argues that the availability of arable land in antiquity created gender norms that continue to affect current gender inequality. We show that countries with greater ancestral arable land have lower levels of gender inequality, better female reproductive health outcomes, and greater...

Individuals bring effort to a group to achieve a common objective. Group membership introduces a free riding incentive, reducing effort, as well as a social responsibility incentive, increasing effort. This paper shows that the free riding effect is stronger. Individuals significantly reduce...

Previous studies have demonstrated that a multitude of options can lead to choice overload, reducing decision quality. Through controlled experiments, we examine sequential choice architectures that enable the choice set to remain large while potentially reducing the effect of choice overload. A...

We propose an allocation rule that takes into account the importance of players and their links and characterizes it for a fixed network. Unlike previous rules, our characterization does not require component additivity. Next, we extend it to flexible networks a la Jackson (2005). Finally, we...
