Now let’s consider the results of a price level increase in the money market. Once the price level rises in an economy, the median price of every goods and services marketed is increasing. Inflation is calculated as the percentage increase in a country’s price level over part period, generally a year. This method that in the period during i m sorry the price level increases, inflation is occurring. For this reason studying the impacts of a price level boost is the very same as examining the impacts of inflation.

You are watching: An increase in the price level will

Inflation have the right to arise because that several factors that will be disputed later in this chapter. For now, we will imagine that the price level boosts for part unspecified reason and consider the consequences.

Suppose the money market is initially in equilibrium at suggest A in figure 18.4 "Effects that a Price Level Increase" with real money it is provided MS/P\$′ and interest rate i\$′. Mean the price level increases, ceteris paribus. Again, the ceteris paribus assumption way that us assume all various other exogenous variables in the model remain addressed at their initial levels. In this exercise, it way that the money supply (MS) and also real GDP (Y\$) stay fixed. Boost in the price level (P\$) causes a to decrease in the actual money it is provided (MS/P\$) since MS remains constant. In the adjoining diagram, this is shown as a shift from MS/P\$′ to MS/P\$″. At the initial interest rate, i\$′, the real money supply has actually fallen to level 2 follow me the horizontal axis, while genuine money demand remains in ~ level 1. This means that money need exceeds money supply and the really interest rate is lower than the new equilibrium rate. Adjustment to the greater interest rate will monitor the “interest price too low” equilibrium story.

Figure 18.4 impacts of a Price Level Increase More intuition worrying these results arises if one recalls the price level boosts will increase the transactions demand for money. In this version, in the name money demand will exceed in the name of money supply and set off the same adjustment process described in the ahead paragraph.

The last equilibrium will occur at allude B on the diagram. The real money supply will have fallen native level 1 come level 2 when the equilibrium interest rate has risen native i\$′ come i\$″. Thus an increase in the price level (i.e., inflation) will certainly cause rise in average interest prices in an economy. In contrast, a diminish in the price level (deflation) will cause a decrease in typical interest rates in an economy.

### Key Takeaway

an increase in the price level (i.e., inflation), ceteris paribus, will cause an increase in median interest prices in one economy. In contrast, a to decrease in the price level (deflation), ceteris paribus, will reason a decrease in average interest rates in an economy.

The term used to describe a percentage increase in a country’s price level end a duration of time. The increase, decrease, or stay the same, the impact on the equilibrium attention rate as soon as the residential price level decreases, ceteris paribus. That increase, decrease, or stay the same, the effect on the equilibrium attention rate when the domestic price level increases, ceteris paribus.
