Væntingarbreytingar, or expectation shifts, is a concept in economics and psychology referring to changes in people's beliefs about future outcomes. These shifts can influence present behavior and economic decisions. For instance, if individuals expect a recession, they might reduce spending and increase savings, which can then contribute to a recessionary environment. Conversely, widespread optimism about future economic growth can lead to increased investment and consumption, potentially fostering that growth.

The phenomenon is closely linked to the self-fulfilling prophecy. If enough people believe something will happen, their actions based on that belief can make it more likely to occur. In financial markets, expectation shifts can drive asset prices. If investors anticipate a company's stock price will rise, they may buy more, driving up demand and thus the price. Similarly, a shift in consumer expectations about inflation can affect current purchasing decisions, either leading to an immediate rush to buy goods before prices increase or a postponement of purchases if consumers expect prices to fall.

Understanding expectation shifts is crucial for policymakers. Central banks and governments often try to manage public expectations to influence economic activity. For example, a central bank might communicate its commitment to keeping inflation low to anchor public expectations and prevent a wage-price spiral. The effectiveness of such communication strategies depends on the credibility of the policymaker and the prevailing economic climate.
