Stepping on a Rake: Replication and Diagnosis

نویسنده

  • John H. Cochrane
چکیده

This paper replicates Sims (2011) “stepping on a rake” model. It derives the model, shows how to solve it, offers some extensions, and boils the paper down to its central ingredient. Sims’ article is important: it is a simple modern economic model that produces a temporary decline in inflation when the central bank persistently raises interest rates. Inflation then rises. The model’s essential feature is long term debt. When interest rates increase, the nominal market value of long-term government debt falls. If fiscal surpluses are unchanged, the price level must fall so that the real value of government debt matches the unchanged real present value of surpluses. The model offers a unified treatment of interest rate targets, quantitative easing and forward guidance that works even in a frictionless setup. ∗Hoover Institution, Stanford University and NBER.

In the presence of long-term debt,...

تأثیر زاویه حمله تیغه و فرکانس ارتعاش بر عملکرد یک چغندرکن ارتعاشی سه واحدی در برداشت کشت‌های 50 سانتی‌متری

Due to yield increase, some farmers in Iran plant sugarbeet in 50-cm row spacing instead of conventional 60-cm row spacing. Low row spacings force farmers to harvest three consecutive rows instead of two alternate rows. This would increase the amount of draft requirement to pull the lifter through the soil. In order to use common medium tractors for pulling the three-unit sugarbeet lifter and p...

Concurrent Locomotive Assignment and Freight Train Scheduling

The locomotive assignment and the freight train scheduling are important problems in railway transportation. Freight cars are coupled to form a freight rake. The freight rake becomes a train when a locomotive is coupled to it. The locomotive assignment problem assigns locomotives to a set of freight rakes in a way that, with minimum locomotive deadheading time, rake coupling delay and locomotiv...
