Preise, or "prices" in English, refer to the amount of money required to purchase goods or services. They can vary based on factors such as demand, supply, and market conditions. Prices are essential in economics as they help determine how resources are allocated in a market economy. In many cases, prices are influenced by competition among businesses. For example, when companies compete to sell similar products, they may lower their prices to attract more customers. Additionally, prices can be affected by external factors like inflation or changes in consumer preferences. Understanding prices is crucial for both consumers and producers.
