Unfortunately, this link is broken with a fractional reserve system and unresponsive interest rate policy from the Fed. Additionally, existing workers will be paid overtime rates to work extra hours, as well as weekend work or night-shift work. However, not all of the extra demand will be satisfied, and the competition to buy goods will bid prices up from P to P’.

As a result of this excess demand, prices will rise and excess demand inflation or demand-pull inflation comes to exist. But demand-pull inflation may also be caused without an increase in money supply—when MEC or MPC goes up causing an increase in expenditures and hence prices. Since inflation is due to excess demand, it is considered controllable by the demand reducing monetary and fiscal policies. Figure 32.7 shows that according to pure supply (cost-push) inflation theorists—in societies of oligopolies, unions and other pressure groups the aggregate supply curve moves upwards from S0 to .S1to S2 whatever may happen to aggregate demand. A usual characteristic of such markets is that the money wage rate is inflexible downward, the result of which is an aggregate supply curve of the kind shown by S0S. With the initial SoS and D0 curves in the Figure 32.7, we can turn to the process by which increases in the money wage rate push up the price level.

Interest Rates and Inflation – Chains of Reasoning

Demand-pull inflation is a crucial concept to understand regarding economic trends. Businesses must be aware of this trend and how it can affect their bottom line. For a business to stay competitive and make money, it is essential to take proactive measures such as adjusting prices or changing production methods. These measures can help a company keep going during inflation. It is important to note that both the original quantity theorists and the modern monetarists, prominent among who is Milton Friedman, also explain inflation in terms of excess demand for goods and services.

This theory shows that when supply is stable, commodity prices rise. Once the economy reaches full employment, the manufacturer fails to increase production further. But in this case, the price level rises as demand continues to expand.

As demand for their product increases, Widgetized needs to increase production. To do this, they need to hire more employees and buy more raw materials. The new employees need to be trained, and the company might pay more than their normal cost in order to get the number of materials they need for widget production. All of these things increase pricing and the potential to trigger other demand-pull inflationary pressures. When the inflation rate rises then demand goods and services usually rises as well because people want to protect their money by buying goods while they are still affordable. Cost-push inflation refers to prices rising due to increased production costs.

Demand Pull Inflation Theories of Inflation

In Keynesian theory, increased employment results in increased aggregate demand (AD), which leads to further hiring by firms to increase output. Due to capacity constraints, this increase in output will eventually become so small that the price of the good will rise. At first, unemployment will go down, shifting AD1 to AD2, which increases demand (noted as “Y”) by (Y2 − Y1).

Demand-pull inflation refers to a rise in prices when the demand for products increases more than their supply. Rapid overseas growth can also ignite an increase in demand as more exports are consumed by foreigners. Finally, if a government reduces taxes, households are left with more disposable income in their pockets. This, in turn, leads to an increase in consumer confidence that spurs consumer spending. In Keynesian economics, an increase in aggregate demand is caused by a rise in employment, as companies need to hire more people to increase their output. Cost-push inflation means prices have been “pushed up” by increases in the costs of any of the four factors of production—labor, capital, land, or entrepreneurship—when companies are already running at full production capacity.

The solution, as always, was to borrow more money and print more money. This cycle of higher prices leading to higher wage demands also leads to increased inflationary expectations, and thereby persistent inflation. This process is explained in my article about the Non-Accelerating Inflation Rate of Unemployment.

In the 1960s, the quantity theory of money was presented in a more advanced form. He is a professor at the University of Chicago in the United States. He was also the recipient of the 1976 Nobel Prize in Economics. Milton Friedman’s view was that there was a constant demand for money. Accordingly, he was of the opinion that inflation is a financial phenomenon at all times and everywhere.

This will lead to the increase in aggregate demand (C +1 + G). If aggregate supply of output does not increase or increases by a relatively less amount in the short run, this will cause demand-pull inflation in the economy, that is, general rise in price level from one period to another. If, for example, in a situation of full employment, the government expenditure or private investment goes up, this is bound to generate inflationary pressures in the economy.

• Cost-push inflation may not be possible in an economy characterized by pure competition.
• Cost-push inflation means prices have been “pushed up” by increases in the costs of any of the four factors of production—labor, capital, land, or entrepreneurship—when companies are already running at full production capacity.
• An enormous increase in government spending will drive up Aggregate Demand.
• In this sense, the ultimate cause of demand-pull inflation is usually the Fed, because it is simply incapable of determining the appropriate interest rate at any given moment.

Does inflation arise from the demand side of the goods, factor and asset markets or from the supply side or from some combination of the two—the so-called mixed inflation. Many economists have come to believe that the actual process of inflation is neither due to demand-pull alone, nor due to cost-push alone, but due to a combination of both the elements of demand-pull and cost-push—called mixed inflation. While these are the main three causes of demand-pull inflation, it can also be triggered by things like government spending, an increase in printing money, or asset inflation when a currency is undervalued. When the economy is doing well, demand for goods and services usually goes up because people have more money to spend. This is a result of more people being employed or a competitive job market that has driven salaries up for many. Consumers also tend to spend more money when they aren’t worried about the status of their job.

The result is that the pressure of demand is such that it cannot be met by the currently available supply of output. In an Aggregate Demand and Aggregate Supply diagram, an increase in the aggregate demand curve leads to an increase in the rate of inflation, i.e., when the aggregate demand for goods and services is greater than the aggregate supply. Demand Pull Inflation is defined as an increase in the rate of inflation caused by the Aggregate Demand curve.

The rationale behind this increase is, for companies to maintain or increase profit margins, they will need to raise the retail price paid by consumers, thereby causing inflation. The theory of cost-push inflation became popular during and after the Second World War. This theory maintains that prices instead of being pulled-up by excess demand are also pushed-up as a result of a rise in the cost of production.

Causes of Demand Pull Inflation

In modern income theory, however, demand-pull is interpreted to mean an excess of aggregate money demand relative to the economy’s full employment output level. The theory assumes that prices for goods and services as well as for economic resources are responsive to supply and demand forces, and will, thus, moves readily upward under the pressure of a high level of aggregate demand. Many supply shocks have contributed to cost-push inflation since the 1970s. The sharp rise in oil prices has increased the cost of production and transportation of every product in the oil-importing countries. Inflation that happened due to the rise in global oil prices in 2022 has significantly impacted the cost of production for many businesses. Therefore, companies have to raise their prices to keep up with the rising costs of materials and labor, increasing overall consumer prices.

To increase aggregate supply, taxes can be decreased and central banks can implement contractionary monetary policies, achieved by increasing interest rates. Looking again at the price-quantity graph, we can see the relationship between aggregate supply and demand. If aggregate demand increases from AD1 to AD2, in the short run, this will not change aggregate supply. Instead, it will cause a change in the quantity supplied, represented by a movement along the AS curve.

How it occurs

Friedman holds that when money supply is increased in the economy, then there emerges an excess supply of real money balances with the public over the demand for money. In order to restore the equilibrium, the public will reduce the money balances by increasing expenditure on goods and services. Basically, inflation is caused by a situation whereby the diagram of demand pull inflation pressure of aggregate demand for goods and services exceeds the available supply of output (both being counted at the prices ruling at the beginning of a period). In such a situation, the rise in price level is the natural consequence. To counter cost-push inflation, supply-side policies need to be enacted with the goal of increasing aggregate supply.

• When concurrent demand for output exceeds what the economy can produce, the four sectors compete to purchase a limited amount of goods and services.
• Therefore, companies have to raise their prices to keep up with the rising costs of materials and labor, increasing overall consumer prices.
• According to classicals, the key factor is the money supply because in accordance with the quantity theory of money only an increase in the money supply is capable of raising the general price level.
• Although an increase in the price level would normally tend to clear markets, this does not take place if demand continues to increase as fast as prices rise.

It would also increase investment spending by firms and businesses. In demand pull inflation, Aggregate Demand D is rising too fast, so these contractionary policies would lower the rise, meaning inflation would still occur but at a lower rate. In his model of inflation excess demand comes into being as a result of autonomous increase in expenditure on investment or consumption, that is, the increase in aggregate expenditure or demand occurs independent of any increase in the supply of money. On the other hand, monetarists explain the emergence of excess demand and the resultant rise in prices on account of the increase in money supply in the economy. To quote Friedman, “Inflation is always and everywhere a monetary phenomenon……. And can be produced only by a more rapid increase in the quantity of money than in output.

In the example above, when the money supply doubles from $ 3000 to $ 6000, the price level doubles from $ 6 to $ 12. If this equation V and T remain constant, then there is a directly proportional relationship between the money supply (M) and the price level (P). This approach (Demand Pull Inflation) points out the prices of goods and services rise as demand increases relative to supply. Government policies that boost productivity and supply can also help ease inflation pressure. For example, infrastructure, education, and technology investments can help improve the economy’s ability to produce goods and services while reducing the stress of inflation.
