The Phillips curve depicts the relationship between unemployment and inflation. In the short run, unemployment and inflation are inversely connected; as one measure rises, the other falls. There is no trade-off in the long run. The short-run Phillips curve was thought to be stable in the 1960s by economists. Economic events in the 1970s put an end to the idea of a predictable Phillips curve. What could have happened in the 1970s to completely demolish a theory? A supply shock has resulted in stagflation.
Stagflation and Aggregate Supply Shocks
Stagflation is a combination of the terms “stagnant” and “inflation,” which describes the characteristics of a stagflation-affected economy: low economic growth, high unemployment, and high inflation. A succession of aggregate supply shocks contributed to the 1970s stagflation. The Organization of Petroleum Exporting Countries (OPEC) raised oil prices dramatically in this example, causing a significant negative supply shock. Increased oil prices translated into much higher resource prices for other items, reducing aggregate supply and shifting the curve to the left. As aggregate supply fell, real GDP output fell, causing unemployment to rise and price levels to rise; in other words, the shift in aggregate supply resulted in cost-push inflation.
Why does unemployment fall while inflation rises?
If the economy overheats, or if the rate of economic growth exceeds the long-run trend rate, demand-pull inflation is likely. Because demand is outpacing supply, businesses raise prices. In the short term, stronger growth may result in decreased unemployment as businesses hire more people. This rate of economic growth, however, is unsustainable – for example, consumers may go into debt to increase spending, but as the economy falters, they cut back, resulting in decreased AD. In addition, if inflation rises, monetary authorities will likely raise interest rates to combat it. A rapid rise in interest rates can stifle economic growth, resulting in recession and joblessness. As a result, an economic boom accompanied by high inflation is frequently followed by a recession. There have been multiple ‘boom and bust’ economic cycles in the United Kingdom. The Lawson craze of the 1980s is an example. We’ve experienced substantial economic growth and reducing unemployment since 1986. Economic growth rates were over 4% per year by the end of the 1980s, but inflation was creeping up to 10%. The government raised interest rates and joined the ERM to combat inflation. Consumer spending and investment fell sharply when interest rates rose.
By 1991, the economic boom had devolved into a serious recession, and anti-inflationary policies had resulted in increased unemployment.
If the government had maintained economic growth at a more sustainable rate throughout the 1980s (e.g., 2.5 percent instead of 5%), inflation would not have occurred, and interest rates would not have needed to increase as high. We could have avoided the surge in unemployment in the 1990s if inflation had remained low.
How do inflation and unemployment effect a country’s economic growth?
In the long run, a one percent increase in inflation raises the jobless rate by 0.801 percent. This is especially true if inflation is not kept under control, as anxiety about inflation can lead to weaker investment and economic growth, resulting in unemployment.
What is the relationship between inflation and employment?
If the economy is producing at its natural potential, increasing inflation by increasing the money supply will temporarily increase economic output and employment by increasing aggregate demand, but as prices adjust to the new level of money supply, economic output and employment will return to their natural state.
In this quizlet, see how inflation and unemployment are linked in the short run.
In the near run, an increase in aggregate demand for goods and services leads to a higher output of goods and services and a higher price level: the higher output reduces unemployment, but the higher prices cause inflation.
What is the link between joblessness and economic growth?
Okun’s law examines the statistical relationship between unemployment and economic growth rates in a country. According to Okun’s law, a country’s gross domestic product (GDP) must expand at a pace of around 4% for one year in order to achieve a 1% reduction in unemployment.
What impact does inflation have on the economy?
Inflation is defined as a steady increase in overall price levels. Inflation that is moderate is linked to economic growth, whereas high inflation can indicate an overheated economy. Businesses and consumers spend more money on goods and services as the economy grows.
What is the long-term relationship between inflation and unemployment quizlet?
An increase in the money supply raises inflation and reduces unemployment over time. The unemployment rate is unaffected by inflation in the long run, and the Phillips curve is vertical at the natural rate of unemployment. When real inflation surpasses predicted inflation, the natural rate of unemployment rises.
Why is there no long-term trade-off between unemployment and inflation?
The Phillips Curve, which is the Keynesian hypothesis that there is a stable trade-off between inflation and unemployment, was introduced in the preceding section. The Phillips Curve was also deduced from the aggregate supply curve, as we explained. In the short run, an upward slope aggregate supply curve implies a downward sloping Phillips curve, implying that inflation and unemployment are tradeoffs. In this part, we’ll show how a neoclassical long-run aggregate supply curve implies a vertical Phillips curve, showing that there’s no long-run inflation-unemployment tradeoff.
