It is well known that movements in lending rates are asymmetric; they rise quickly and sharply, but fall slowly and gradually. Not known is the fact that the asymmetry is stronger the less developed a country's financial system is. This new fact is here documented and explained in a model with an...

We present a multi-city economic model to study the endogenous choice of migration and to evaluate various policy alternatives during a pandemic. We combine a traditional epidemic dynamic model with endogenous migration decisions between cities and provide analytical solutions under two...

We construct a model of bubbles where an asset can be used as collateral primarily due to higher-order uncertainty: while both a lender and a borrower know that the intrinsic value of the asset is low, they may still believe that a “greater fool” exists who will purchase it at a much higher...

How can fire sales for financial assets happen when the economy contains well capitalized, but non-specialist investors? Our explanation combines rational expectations equilibrium and "lemons" models. When specialist (informed) market participants are liquidity-constrained, prices become less...
