Preface
The text introduces the concept of supply and demand with a focus on the natural gas industry in the United States. It highlights how new drilling technologies led to increased natural gas production, making the U.S. the world's largest producer. The adoption of hydraulic fracturing had a significant impact on energy production. Additionally, it explains how changes in demand and supply affected natural gas prices, leading to economic impacts such as lower heating costs and job creation in the U.S. The text also discusses how traffic congestion in cities can be managed through economic strategies like congestion pricing. Examples from cities like London and Moscow illustrate how raising the price of driving can help reduce traffic jams.

Preface
Congestion pricing has been implemented in cities like London to reduce traffic, resulting in a significant decrease in overall traffic and an increase in the use of alternative modes of transportation. In the United States, pilot programs have been introduced to study congestion pricing, such as in Los Angeles County. The law of demand states that higher prices lead to a decrease in quantity demanded, with demand curves typically sloping downward. Factors that can shift the demand curve include changes in the price of related goods, income, tastes, expectations, and the number of consumers. In the fashion industry, shifts in demand have impacted the livelihoods of models, with changes in preferences leading to lower prices paid to models.
