By developing a canonical model of a monetary economy (i.e., where the circulation of liquid assets is essentia...

The cash-in-advance constraint provides a transactions demand for money, but this is not sufficient to guarantee the determinacy of the price level if liquidity is costless or the price level is uncer...

I discuss some simple microfoundations for Liquidity Deflation, a concept put forward in Calvo (2016 a and b), which can give rise to liquidity trap conditions under perfectly flexible prices. Unlike in Keynes (1936), this is a Supply Side Liquidity Trap. Moreover, modeling the policy interest rate as the rate of return on money-like instruments à la Calvo and Végh (1995), denoted by i!, I show...
