Economics q7(inflation)

  1. 1. Q7: Inflation By Ian McCarthy and Kelvin Weymes
  2. 2. What is The Multiplier? • The multiplier Is the number of times an injection of money leads to an increase in the national income. The size of the multiplier depends on • The marginal prosperity to consume • The marginal prosperity to save • The marginal prosperity to tax • The marginal prosperity to import
  3. 3. Example of The Multiplier from Economic History • The Economic table of Francois Quesnay, laid the foundation of the Physiocrat school of economics which is credited as the first precise formulation of interdependent systems in economics and the origin of multiplier theory. • In the economic table, one sees variables in one period feeding into variables in the next period and a constant rate of flow yields geometric series, which computes a multiplier. • The modern theory of the multiplier was developed in the 1930s, by Kahn, Keynes and Giblin.
  4. 4. What is Inflation? • Inflation is the rate at which the general level of prices for goods and services is rising and subsequently purchasing power is falling. • This occurs when demand for products and services by consumers is stronger than the supply of the desired products and services. • Debtors gain in the short term as they can repay the load with inflated currency which is worth less. • An inflation rate is the percentage increase in the price of goods per year.
  5. 5. Example of Inflation from Economic History • Zimbabwe - 2006 to 2009 • Inflation reached 66,212 % in December 2007, the highest in the world at that time. • In 2009 the Zimbabwe government issued the Z$100 trillion bill as inflation eroded purchasing power. • Shortly after the Zimbabwean dollar was abandoned in favour of foreign currencies. • A roll of toilet roll cost 145,750 Zimbabwe dollars
  6. 6. Zimbabwe Inflation The Zimbabwean $100 trillion bill is now a novelty item
  7. 7. Example of other Inflation from Economic History Highest Monthly Inflation Rates in History Country Month with highest inflation rate Highest monthly inflation rate Equivalent daily inflation rate Time required for prices to double Hungary July 1946 1.30 x 10 % 195% 15.6 hours Zimbabwe Mid-November 2008 (latest measurable) 79,600,000,000% 98.0% 24.7 hours Yugoslavia January 1994 313,000,000% 64.6% 1.4 days Germany October 1923 29,500% 20.9% 3.7 days Greece November 1944 11,300% 17.1% 4.5 days China May 1949 4,210% 13.4% 5.6 days 16
  8. 8. What is Deflation? • Deflation is a decrease in the general price level often caused by a reduction in the supply of money or credit, it can also be caused by a decrease in government personal or investment spending. • Deflation is an indication that the economic conditions deteriorating. • It is also usually associated with unemployment.
  9. 9. Example of The Deflation from Economic History The Great Depression 1929-1940 • The Great Depression plunged the American people into an economic crisis unlike any endured country had seen before or since. • It was worst and longest downturn in economic history, it threw millions of hardworking individuals into poverty and for more than a decade neither the free market nor the federal government was able to restore prosperity. • Unemployment reached 24.1 percent in 1993 , the stock market crashed, and consumers lost much of their savings.
  10. 10. Six problems caused by high inflation • Rising prices causes worsening poverty as the essentials for survival become more expensive which makes it less attainable to those with low income. • It creates uncertainty and entrepreneurs will be reluctant to invest which will slow down potential for economic growth • High inflation can reduce the incentive to save.
  11. 11. Six problems caused by high inflation • Shoe leather costs – when prices are unstable there will be an increase in search times to discover more about prices. It increases the opportunity cost of holding money so more people make visits to their banks. • Consumers and businesses on fixed incomes will lose out . • Menu costs – is extra costs to firms of changing price information which can be important for companies who rely on bulky catalogues to send price information to customers.

  22. 22. Oil Crisis 1973 In response to Yom Kippur War – OPEC Changes : • Announced Oil Embargo • Raise in all trade prices • Unified Block on all exports • Oil price raised by 70% • Gave OPEC power
  23. 23. What did this lead to? • Worldwide recession • Long term possibility of high oil prices • Smaller Quantities of Oil for more money • Shortage of Petrol • Heating, Electricity and Gas became an issue • Saving energy – Oregon Christmas lights ban • Unemployment/ Wage cuts– not as many people needed • Campaigns – “Don’t be Fuelish”
  24. 24. Evidence of Gas Shortages
  25. 25. Power Shortages
  26. 26. Alternatives 1974- Prices raised 4 times higher than they had at the start of the Oil Crisis  • New alternatives • Cheaper ways to live • Cycling to work • Solar power energy • Japan- Produced Cars less petrol • Moved on to electronics
  27. 27. Demand Pull Inflation Definition• The demand for a certain product is greater than the amount of goods being supplied • When there are high demands, prices will rise • Individuals are trying to purchase the same good, the price will inevitably increase • The complete opposite of Cost Push Inflation
  28. 28. Dublin’s Property Boom • Full employment- More money • Living like the United States • People thought boom last forever • People borrowing 8-10 times monthly income • High demand for houses • Houses limited • Prices rose • Oversupply of apartments

  31. 31. Great Depression • Herbert Hoover raised taxes • Made Depression worse • Keynes thought- “In the long run we are all dead” • Start by reducing interest rates • Increasing spending in infrastructure • Increase in employment = increase in spending • Get us back to a cycle of: • Receiving income  spending it back into the economy
  32. 32. What we should do in a Boom 2. According to Keynes – Booms are not good as it has to lead to Bust • We want a more steady economy • We don’t want a big boom then a big bust • Counter Cyclical Fiscal Policies• Increasing taxes in booms • Cutting back in government spending
  33. 33. What does this lead to? • Tax tends to decrease demand when the economy is booming • E.g. property prices not going to an extreme in price • Leads to people not spending as much • Prepares us for the worst • Keeps us steady • Spending enough to keep cycle going • Not going from one extreme to another • Government have money – harder for a recession to hit • Economy is stronger
  34. 34. Keynes Multiplier Effect 3. If a government invests money into a business  That business would then use that money to make goods and pay wages With the goods they make,  they then sell on -They use the profits to buy the items necessary for making the product -This money is then going back into the economy and slowly increasing Creating a circular flow of income
  35. 35. Example • Example – Ireland exports – Government invested a lot of money into IT  Now exporting a lot of their goods which increases the multiplier effect
