MAIN RESULTS
1. Show that a model with capital accumulation and sticky prices but no investment frictions has counterintuitive properties.
• Real interest rates rise with monetary expansion (Tobin, 1955; King, 1993)
• Increases in government purchases lower output and real interest rates in the short run
• Complements earlier work with J. Fernald on contractionary technology improvements
2. Suggest a friction that might help address both problems: Investment planning costs
3. Show that planning costs make the model more plausible • Short-run fiscal policy expansionary (restores Keynesian Cross logic)
• Real interest rate effect from monetary expansions
• Propagation of shocks matches data better
4. Q-theory-style capital adjustment costs generally not a substitute for planning costs

WHY EXPENDITURE INERTIA? Supposing we just want to match evidence that money shocks have delayed effect on output Then we could think of mechanisms to create inertia in each element of private expenditure: ( )Y C I G NX= + + + OR More parsimoniously, could build inertia into production (e.g., make L costly to adjust, output precommitments) ( ),Y F K L=

But evidence says that G shocks have immediate output effect [Ramey-Shapiro (1998), Blanchard-Perotti (2002), Mountford-Uhlig (2002), Perotti (2004)] Then we need the inertia in expenditure, not production Investment inertia is consistent with micro evidence (Edge, 2000; Lamont, 1999) Complements consumption inertia; e.g., habit formation Macro effects akin to “time to plan” (Christiano and Todd, 1996), not “time to build”—need to slow down ordering the new investment goods

BUILDING BLOCKS OF THE MODEL
Baseline: Basic RBC model, Calvo pricing. Capital accumulation; no investment frictions •
•
King-Plosser-Rebelo (1988) utility Assume EIS (σ) less than 1 (Basu-Kimball, 2002). Implies C and N (labor) complements Real rigidities from: labor “attachment,” intermediate goods, concave demand curve •

Φ is increasing and convex This Calvo-like formulation has the advantage that there is good micro data on 1/γ (Edge, 2000). The results are much more sensitive to choice of γ than to convexity of Φ Very small planning costs can generate significant delays—with projects lasting about a year, a 6-month delay requires costs such that a 10% increase in project starts raises overall investment costs by 0.0096%
