St. Louis Fed President James Bullard discussed factors that are weighing on the decision to begin normalizing U.S. monetary policy and the recent removal of the word “patient” from the FOMC statement, during the 24th Annual Hyman P. Minsky Conference, in Washington, D.C. He said that now...

This paper develops an analytically tractable general-equilibrium model of inventory dynamics based on a precautionary stockout-avoidance motive. The model’s predictions are broadly consistent with the U.S. business cycle and key features of inventory behavior. It is also shown that...

Conventional wisdom has it that inventory investment destabilizes the economy because it is procyclical to sales. Khan and Thomas (2007) show that the conventional wisdom is wrong in a general equilibrium (S,s) model with capital. We argue that their finding is not robust—the conventional...

Aguiar-Conraria and Wen (2008) argued that dependence on foreign oil raises the likelihood of equilibrium indeterminacy (economic instability) for oil importing countries. We argue that this relation is more subtle. The endogenous choices of prices and quantities by a cartel of oil exporters,...

Investment booms and asset "bubbles" are often the consequence of heavily leveraged borrowing and speculations of persistent growth in asset demand. We show theoretically that dynamic interactions between leveraged borrowing and persistent asset demand can generate a multiplier-accelerator...

Firm-level investment is lumpy and volatile but aggregate investment is much smoother and highly serially correlated. These different patterns of investment behavior have been viewed as indicating convex adjustment costs at the aggregate level but non-convex adjustment costs at the firm level....

China’s average household saving rate is one of the highest in the world. One popular view attributes the high saving rate to fast rising housing prices and other costs of living in China. This article uses simple economic logic to show that rising housing prices and living costs per se cannot...

The current global-imbalance literature (which explains why capital flows from poor to rich countries) cannot explain China’s foreign asset positions because capital cannot flow out of China under capital controls. A related but deeper puzzle that this literature fails to address is China’s...

We use a general equilibrium finance model that features explicit government purchases of private debts to shed light on some of the principal working mechanisms of the Federal Reserve’s large-scale asset purchases (LSAP) and their macroeconomic effects. Our model predicts that unless private...
