This paper proposes to exploit data on expectations to identify news shocks in business cycles. News shocks work through changes in expectations, so data on expectations contain important information for identification. We demonstrate this by estimating a DSGE model augmented with news shocks...

We show that a simple and intuitive three-parameter equation fits remarkably well the evolution of the gross domestic product (GDP) in current and constant dollars of many countries during the times of recession and recovery. We then argue that it can be used to detect shocks and discuss its...

We show that a simple and intuitive three-parameter equation fits remarkably well the evolution of the gross domestic product (GDP) in current and constant dollars of many countries during times of recession and recovery. We then argue that this equation is the response function of the economy...

This paper shows that a production network facilitates expectations-driven business cycles. Through input-output linkages, changes in expected demand can cause business-cycle fluctuations and endogenous movements in the Solow residual. When inputs must be purchased one period in advance,...

The adaptive learning approach has been fruitfully employed to model the formation of aggregate expectations at the macroeconomic level, as an alternative to rational expectations. This paper uses adaptive learning to understand, instead, the formation of expectations at the micro-level, by...
