Step-by-step explanation:
When an economist wants to test a theory on why the price of a product like gasoline fluctuates, they may face several challenges in obtaining information. Some of these problems include:
- Access to accurate and reliable data on factors such as supply, demand, production costs, and market conditions
- Understanding and accounting for the various variables that exist in the market for gasoline, which can include geopolitical events, weather conditions, government policies, and economic trends
- Determining which variables are more important than others, as some factors may have a larger impact on price fluctuations, such as changes in oil prices or government regulations, while others may have a smaller or more localized effect
By conducting thorough research, collecting data from reliable sources, and performing statistical analysis, an economist can overcome these challenges and gain insights into the factors that drive fluctuations in gasoline prices.
