2.1. Relationship between inflation and stock prices
In accordance with Feldstein (1980), stock prices boost when inflation rate is at high constant rate. On the contrary, the stock prices fall when the expected inflation rate rises.
Feldstein (1980) also demonstrated effect of inflation on stock prices through corporate income taxation, cost depreciation and taxation of nominal capital gains.
When inflation rate is higher, the cost depreciation affects corporate earnings since the depreciation is calculated based on historical cost, which is not influenced by the rising inflation rate.
The depreciation is less than it is supposed to be drives the real taxable profit to go up (Hong,1977).
