Using structural shocks to identify models of investment
This paper uses the response of investment to identified structural shocks to investigate some key issues, including the nature of adjustment costs and investment's responsiveness to user cost. In the estimation, the model parameters are chosen to match as closely as possible the impulse responses from an identified VAR. In the preferred results, both investment- and capital-stock adjustment costs are important; the size of the capital-stock adjustment costs is in line with estimates from firm-level studies; the investment-adjustment costs suggest rapid adjustment of investment to its desired ...

November 2014 Update of the FRB/US Model
This FEDS Note is a companion to the most recent release of the FRB/US model of the U.S. economy available at http://www.federalreserve.gov/econresdata/frbus/us-models-about.htm. The purpose of this note is twofold. First, it briefly outlines and describes the changes to the structure of the public version of FRB/US since its introduction in the spring of 2014. In addition, it compares the dynamics of the current version to that of the original version in response to key shocks.

Modeling aggregate investment: a fundamentalist approach
This paper applies some lessons from recent estimation of investment models with firm-level data to the aggregate data with an eye to rehabilitating convex costs of adjusting the capital stock. In recent firm-level work, the response of investment to output and other "fundamental" variables is interpreted in terms of the traditional convex-adjustment-cost model, implying annual capital-stock adjustment speeds on the order of 15 to 35 percent. In aggregate data, I find that this "fundamentalist" model can account for the reduced-form effect of output on investment and the estimated ...

Estimates of the productivity trend using time-varying parameter techniques
In the second half of the 1990s, U.S. productivity growth moved up to rates not seen in several decades. In this paper, I use time-varying parameter techniques to isolate trend from cyclical movements in productivity and to obtain an estimate of the trend rate of productivity growth. I examine models both with and without an explicit role for capital accumulation. I find that in the models without an explicit role for capital accumulation, trend productivity growth is estimated to have moved up from around 1-1/2 percent in the period from the early 1970s to the mid 1990s, to about 2-1/2 ...
