<p>Deflation, a macroeconomic phenomenon, refers to a general decline in prices for goods and services in an economy over a period of time. This is the opposite of <a href="/NewSite/encyclopedia/inflation/" class="ency-link">inflation</a>, where prices rise. Deflation can be caused by various factors, including a decrease in the money supply, an increase in productivity leading to lower production costs, or a decrease in demand for goods and services.</p>

<h2>How It Works</h2>
<p>Deflation works through several mechanisms. When the money supply decreases, people have less money to spend, which reduces demand for goods and services. This decrease in demand can lead producers to lower prices to attract customers. Alternatively, if the demand for goods and services decreases due to factors like a recession, producers may lower prices to stimulate demand. Additionally, if productivity increases, producers can make more goods with the same resources, leading to lower prices.</p>

<h2>Why It Matters</h2>
<p>Deflation matters for several reasons. Firstly, it can lead to a decrease in consumer spending and investment, as people and businesses wait for prices to fall further before making purchases. This can exacerbate a recession or slow down economic growth. Secondly, deflation can increase the real value of debt, making it harder for borrowers to repay. Lastly, deflation can lead to a deflationary spiral, where expectations of falling prices lead consumers and businesses to delay spending and investing, further exacerbating the deflation.</p>
