Another important factor for determining consumption is the expectations about future income, prices and wealth. For example, if consumers expect a stagnation in the
economy, they expect that they will lose their jobs or their working hours will be reduced. Expectations are subjective opinions about the future. It is therefore extremely difficult to observe and measure them. This causes different problems
in terms of analyzing the effects of expectations on consumption. For this reason, expectation surveys are periodically conducted by policy-makers and expectations are monitored in this way.
