Consumption, price expectations and deflatively-recessive spiral

This thesis examines the relationship between price expectations and current consumption. Especially, whether the postponement of final consumption expenditure by households, as a result of their declining price expectations; which may be a deflatively-recessive spiral starter; coincides with economic theory and practice. Based on this, appropriate economic policy recommendations can be drawn. The analysis in the framework of intertemporal consumer model of two periods extended by inflation and the risk confirms this hypothesis. Price expectations positively affect current consumption through the intertemporal substitution effect of real interest rate changes. However, certain assumptions must be fulfilled. Especially, the economy must be in a fixed nominal interest rate environment, the substitution effect must not be offset by the effect of a change in the expected real disposable income or the income effect of the change in the real interest rate and the households must have a higher disposable income so that they can afford to postpone consumption. These findings coincide with the conclusions of the empirical analyzes mentioned in this thesis.
