The Role of High Unemployment in Reducing Inflation After the 1970s Oil Shocks

Economic Impact of an Energy Price Surge

Consider an economy described by a wage-setting (WS) and price-setting (PS) framework, which in turn determines the relationship between inflation and unemployment. If this economy experiences a sudden and permanent increase in the world price of oil, what is the most accurate description of the resulting changes within this framework?

An economy, initially in a stable equilibrium, experiences a sudden, one-off increase in the world price of oil. According to the integrated wage-setting/price-setting and Phillips curve framework, arrange the following events in the correct chronological order to describe the economy's adjustment process.

Analyzing an Oil Price Shock

According to the standard wage-setting and price-setting framework, a one-off increase in the world price of oil leads to higher inflation primarily because it shifts the wage-setting curve upwards, reflecting workers' demands for higher real wages to cover increased energy costs.

Mechanism of an Oil Price Shock

An economy experiences a one-off, permanent increase in the world price of oil. Match each economic event or cause with its direct consequence within the wage-setting/price-setting (WS-PS) and Phillips curve framework.

In an economic framework where firms set prices as a markup over their costs, a sudden increase in the world price of oil reduces the real wage that firms can profitably offer. At the initial level of unemployment, this creates a positive __________ between the wage workers demand and the wage firms offer, triggering an upward shift in the economy's inflation-unemployment trade-off.

An economy is in a medium-run equilibrium with stable inflation. It then experiences a significant and permanent increase in the global price of a key imported input, like oil. Within a framework where firms set prices as a markup over costs and wages are determined by bargaining, which statement best explains why this shock can lead to a period of rising inflation combined with rising unemployment?

An economy, where inflation arises from the interplay between wage-setting by workers and price-setting by firms, is hit by a large, permanent increase in the global price of oil. A policy advisor argues, 'To prevent a rise in unemployment, the central bank should use expansionary policy to maintain the current level of aggregate demand and employment.' Which of the following statements provides the most accurate evaluation of this policy recommendation based on this economic framework?
