Chapter 11 Flashcards
Defn. Inflation
an economic situation where there is a sustained increase in the overall level of prices or general price level in an economy
Inflation rate is positive/negative meaning
Note: Most common measure of inflation is the annual percentage change in CPI
Positive:
- increase inflation rate means price increase faster
- decrease inflation rate (DISINFLATION) means price increase slower
Negative:
- price decrease compared to previous time period (DEFLATION)
Headline inflation vs Core inflation
headline inflation:
tracks the price of goods and services generally consumed by households
core inflation:
measured by considering a basket of goods and services that excludes the price of energy and food because these are volatile and have temporary fluctuations in them
Degrees of inflation
Mild inflation: price level rises slowly (usually less than 2%)
Hyperinflation/ Galloping/ Runaway inflation: prices rises so fast that money ceases to be a medium of exchange and normal economic activity may break down
Creeping inflation: between both ^
Types of inflation
- Demand-pull inflation
- Cost-push inflation
Defn. Demand-pull inflation
occurs when GPLs rise due to persistent increase in AD in the economy that are not matched by the output of goods and services (AS)
Causes of demand-pull inflation
Causes are the changes in the determinants of C, I, G, (X-M)
Explanation eg.:
one possible cause of demand-pull inflation can arise from positive business expectations.
In a period where firms are optimistic about the future due to rising economic growth and falling unemployment, investments in a country may rise. (I).
Rise in investments will lead to a rise in AD.
The initial rise in AD will cause an unplanned fall in firm’s inventory. To maintain their inventory, firms need to employ more resources such as labour. As more labour are hired, they receive more in wages. The purchasing power of the labour force increases. This leads to multiple rise in induced consumption. Each subsequent rise in induced consumption will be increasingly smaller. This results in a multiple rightward shift in the AD curve, where AD is rising at a decreasing rate. The overall rise in AD from AD0 to AD1 has resulted in multiple rise in RNY from Y0 to Y1.
In fig. 2, when AD rises along the intermediate range of AS from AD0 to AD1, shortage occurs in the economy. This is because at the intermediate range, resources are becoming increasingly limited and AS is unable to meet the rise in AD. the shortages of goods and services drives up prices. thus, demand-pull inflation occurs as GPL starts to slowly rise from P0 to P1. RNY also increases from Y0 to Y1.
Defn. Cost-push inflation
occurs when GPL rise due to rising costs of production (eg increase in wages, rent, interest etc.) Hence cost-push inflation is a supply-side phenomenon
Causes of Cost-push inflation
- Rising cost of production
-> wage-push inflation
-> imported inflation (rising commodity prices, depreciation of domestic currency)
-> tax-push inflation - Falling productive capacity
Explanation:
Firms facing a rise in costs, would respond by cutting back on production. Thus, an increase in the COP causes the AS curve to shift upwards from AS0 to AS1. At the current price P0, there is a shortage of goods and services. Shortages drives up prices from P0 to P1. Thus, cost-push inflation occurs as GPL starts to rise from P0 to P1. Real NY falls from Y0 to Y1 as firms cut back on their production
Consequences of inflation on households
- Mat SOL
-> Inflation leads to higher cost of living. With higher prices, pp of incomes/wages falls. mat sol fall - savings
-> WIth falling pp pf income due to inflation, more money will be needed to purchase the same amount of goods in order to maintain the same mat so. If a larger proportion of income is used to consumer goods, less proportion of income is available for savings. Hence, there would be a fall in overall savings.
-> Inflation also discourages savings because the real value of savings (the pp of savings) is eroded as prices continue to rise. Although the reward for savings is the interest that is earned, inflation can erode the value of the interest earned.
Consequences of mild dd-pull inflation on firms
- producers may experience higher profit margins amid rising prices since factor costs (labour, energy, raw mat cost etc.) are unlikely to rise in the short term due to long term contracts between firms and suppliers of resources.
- since final product prices rises faster than cost of FOP, greater production and investment may be encouraged due to higher expected returns.
- this would lead to a higher level of investment, and hence future rise in productive capacity, as well as rising employment.
- thus, mild demand-pull inflation can generate higher employment and EG
Consequences of cost-push inflation on firms
- COP rises initially, leading to lower profits or even losses for firms
- businesses that earn a lower profit may choose to either produce less or even shut down. If so, overall production levels may fall together with falling investments, employment and growth levels.
- firms would need to become more efficient and innovative in order to survive a cost-push inflation
Consequences of high rates inflation on firms
- regardless of cost-push or dd-pull inflation, high rates of inflation are associated with uncertainty.
- with rising prices, firms may have difficulty estimating their future costs and thus profits accurately. this may have adverse effects on the level of planned capital investment and hence output of firms
- rising uncertainty results in higher risk in investments. firms would undertake such high risk investments only if they are guaranteed higher returns. due to rising risk, current investments may be abandoned if their expected returns are too low to cover the increased risk. the fall in investment will hence reduce the output of the firms
Effects of inflation
Internal:
1. Households
2. Firms
3. Govt
4. Economy
External:
1. Current Account (Balance of trade)
2. Capital and Financial Account
3. Balance of payments (BOP) and exchange rate
Consequences of inflation on Current Account (Balance of trade)
During inflation, price of domestic goods rise thus making domestic goods to be more expensive in foreign markets. the rising export prices would then, ceteris paribus, lead to a fall in the Qd for exports. At the same time, foreign goods are now relatively cheaper in the home market compared to locally produced goods. imports are now cheaper substitutes, and ceteris paribus, the trade balance will deteriorate as net export revenue now falls. falling trade balance would worsen the current account.
