This figure presents a flow chart of the model's structure. In the center of the figure are monopolistically competitive intermediate goods producers (of the model's two goods, CBI and KB), who produce their goods using labor and capital input (from households and capital intermediaries, respectively) and who sell their output to final goods producers for each good. The final goods producers sell their goods to households and the intermediaries who purchase consumer durable capital, residential capital, and non-residential capital. Each of the three capital intermediaries rent their capital to either the household (durables and residential capital) or firms (non-residential capital). Finally, the central bank sets the short-term nominal interest rates, which affects all other entities in the model.

Real durables consumption falls about 1/4 percent initially and quickly returns to baseline.

This figure presents the response of 8 variables to a 1 percent (not at an annual rate) shock to overall total factor productivity (TFP). Real GDP increases about 0.8 percent on impact and rises further to about 1.2 percent above baseline after six years; Real consumption increases about 0.3 percent on impact and rises further to about 0.8 percent above baseline by the end of six years; Real durables consumption increases about 1.2 percent on impact and further to more than 1.4 percent above baseline after one year, and then slowly falls to around 1 percent above baseline; Real housing investment rises about 1.2 percent on impact and slowly thereafter, remaining nearly 3 percent above baseline after six years; Real (nonresidential) investment rises about 1.5 percent on impact and by nearly 2.5 percent after two years; the response of hours is muted, at about 0.1 percent on impact and peaking at about 0.4 percent at about two years; the federal funds rate falls about 0.1 percent in the first year; and inflation (on a core or overall PCE price basis) falls about 0.1 percent in the first year.
This figure presents the data (blue line) and smoothed model observables (black line, which equal the data minus the model's estimated measurement error for that data) along with confidence intervals for the smoothed observables over the period 1984Q$ to 2008Q4; in each case the data have had their means or trends removed. Real GDP growth follows its familiar path, with declines in the recessions of the early 1990s, early 2000s, and in 2008; the smoothed observable largely follows the same path. Real nondurables consumption growth follows a path similar to that of GDP but with lower volatility; the smoothed observable largely follows the same path. Real nonresidential investment growth is volatile and showed an especially large decline around the early 2000s recession; the smoothed observable largely follows the same path. Real durables consumption growth is volatile, with its most pronounced decline over this sample in 2008; the smoothed observable largely follows the same path. Real housing investment declined strongly in the early 1990s and after 2005; the smoothed observable largely follows the same path. The growth of the real wage is volatile with no clear cyclical pattern; the smoothed observable largely follows the same path. Aggregate hours (per capita, detrended) peaks before each recession and falls during the recessions and for awhile after the recessions. PCE inflation is much more volatile than its smoothed observable, reflecting the absence of food and energy prices from the model. Core PCE inflation is higher through the early 1990s (that is above zero, which corresponds to above 2 percent at an annual rate, as that is the model's steady-state rate of inflation); the smoothed observable largely follows the same path. Finally, investment good inflation (that is, inflation in the PCE durables price index) looks similar to the core PCE inflation measure; the smoothed observable largely follows the same path.
This figure presents the innovations to the exogenous processes in the model (risk premium, exogenous demand, wage markup, funds rate shock, capital goods technology, overall TFP, non-investment price markup, investment price markup, housing risk premium, durables risk premium, capital risk premium) . All of these innovations should be independently and identically distributed; as a result, there should not be evident patterns in the innovations. For the most part this is true, with the innovations looking likely random paths.
This figure presents the exogenous drivers in the model. All of these are AR(1) processes and hence could have interesting cyclical properties. The risk premium rises sharply during each recession; exogenous demand is very strong in the early 1990s and weak from 2003 to 2006; the housing risk premium rose sharply after 2004; the durables risk premium is volatile and random; the capital risk premium rose after 2000 and remained high after that point.
