We use a dynamic factor model to provide a semi-structural representation for 101 quarterly US macroeconomic series. We find that (i) the US economy is well described by a number of structural shocks between two and six. Focusing on the four-shock specification, we identify, using sign restrictions, two non-policy shocks, demand and supply, and two policy shocks, monetary and fiscal. We obtain ...

the purpose of this paper is to examine the effects of monetary, fiscal and oil revenue shocks on macroeconomic variables in the framework of rule and discretionary monetary policy. to end this, we use a new keynesian dynamic stochastic general equilibrium (dsge) model. given the dominant role of oil in the country, we consider the role of oil shock in the model through different channels. the ...

What is the role of common shocks in driving the business cycles of small open economies? We investigate this question in a structural small open economy model featuring a realistic debt adjustment cost and common shocks. We estimate the model using data for 17 small developed and developing countries between 1900 and 2006. The estimated model attributes nearly 50% of the output ‡uctuations ove...

Investment-specific technology (IST) shocks are often interpreted as multi-factor productivity (MFP) shocks in a separate investment-producing sector. However, this interpretation is strictly valid only when some stringent conditions are satisfied. Some of these conditions are at odds with the data. Using a two-sector model whose calibration is based on the U.S. Input-Output Tables, we consider...

Changes in patterns of organizing often follow disruptions, so-called shocks, in the way that people understand their organization and organizing practices. People engage in a process of sensemaking, and new meanings emerge to guide future practices. Yet, organizations often deal with such shocks in ways that do not lead to any fundamental differences in the observed patterns of organizing prac...
