In the conduct of economic policies, governments and central banks must constantly balance between two often conflicting imperatives: stimulating growth without letting inflation run out of control, and supporting employment without destabilizing public finances.
When these adjustments take the form of repeated alternations between expansion and restriction, economists speak of “stop and go” policy. This expression illustrates an economic management marked by successive phases of acceleration followed by slowing of activity.
An alternating cycle of stimulus and austerity
Stop and go designates an economic strategy consisting of alternating periods of stimulating the economy with phases of tightening intended to correct the imbalances created by that very stimulus.
In the “go” phase, public authorities seek to support growth through increased budgetary spending, tax cuts, or an accommodative monetary policy. The aim is generally to boost investment, consumption and employment.
When this dynamic triggers inflationary pressures, a widening external deficit or a deterioration of public finances, authorities then move to the “stop” phase. They reduce spending, raise interest rates or adopt austerity measures in order to slow the economy and restore certain macroeconomic balances.
A reactive management of imbalances
This approach often reflects a difficulty in maintaining a sustainable pace of growth. Stop and go typically appears when economic policies react to imbalances successively rather than preventively. An overly strong stimulus creates tensions, then too brutal a correction slows activity excessively, sometimes triggering a new need for stimulus.
Historically, this logic has marked several economies over the 20th century, notably in contexts where governments sought to quickly support demand without always having sufficient structural margins. It is often associated with a form of short-term conjunctural steering, more oriented toward immediate reaction than toward long-term stability.
A model often criticized
The main critique aimed at stop and go is that it can create instability and harm economic visibility. Firms, investors and households struggle to anticipate the future environment when policies frequently change direction. This unpredictability can curb investment decisions and reduce the overall effectiveness of public measures.
Moreover, an economy subjected to repeated stop-and-go cycles risks alternating between overheating and slowdown without achieving sustainable growth. This is why many economists today advocate for more gradual policies, more focused on structural reforms and macroeconomic stability.
Stop and go nevertheless remains an essential notion for grasping certain sequences of economic policy, reminding that an excessively oscillating management of the conjuncture can sometimes sustain the imbalances it seeks to correct.
