Standard models of aggregate demand treat money and credit asymmetrically; money is given a special status, while loans, bonds, and other debt instruments are lumped together in a "bond market" and suppressed by Walras' Law. This makes bank liabilities central to the monetary transmission...

This chapter studies how incomplete information helps accommodate frictions in coordination, leading to novel insights on the joint determination of expectations and macroeconomic outcomes. We review and synthesize recent work on global games, beauty contests, and their applications. We...

We explore the consequences of safe asset scarcity on aggregate demand in a stylized IS-LM/Mundell Fleming environment. Acute safe asset scarcity forces the economy into a "safety trap" recession. In the open economy, safe asset scarcity spreads from one country to the other via capital flows,...

We formulate a medium-scale DSGE model that emphasizes a strong interplay between a roundabout production structure and a working capital channel that requires firms to borrow funds to finance the costs of all their variable inputs and not just the wage bill. Despite an absence of...

We formalize the Keynesian insight that aggregate demand driven by sentiments can generate output fluctuations under rational expectations. When production decisions must be made under imperfect information about demand, optimal decisions based on sentiments can generate stochastic...
