Demand side causes of DeflationDemand side causes of Deflation
• A Large (adverse) Fall in AD• Exogenous shocks to the economy• A global recession leading to a fall in exports
and investment• A rise in the exchange rate (leading to lower exports and
cheaper imports)• Declines in domestic and international asset prices
– Deliberate attempts by macroeconomic policy to reduce AD through tightening of fiscal and/or monetary policy

Supply side causes of deflationSupply side causes of deflation
• An Increase in Long Run Aggregate Supply• The supply potential of the economy has been boosted
by a series of beneficial shocks such as
• Impact of rapid technological advances• Reductions in the international prices of commodities and capital
goods• Higher productivity which drives down unit cost of production
– Exploitation of economies of scale leading to lower LRAC• Excess supply in some industries due to over-investment in new
capital machinery i.e. deflation results from a persistent demand deficit over existing and potential productive capacity.

Consequences of DeflationConsequences of Deflation• Holding back on spending: • Consumers may opt to postpone demand if they expect prices to fall further
in the future
• Debts increase: The real value of debt rises when the general price level is falling and a higher real debt mountain can be a drag on confidence– Mortgage payers on fixed mortgage interest rates will see the real cost of
servicing their debt increase
• The real cost of borrowing increases: Real interest rates will rise if nominal rates of interest do not fall in line with prices
• Lower profit margins: This can lead to higher unemployment as firms seek to reduce their costs.
• Confidence and saving: Falling asset prices such as price deflation in the housing market hit personal sector wealth and confidence –leading to further declines in AD. Higher savings can lead to the paradox of thrift
