Economics is defined as a social science that examines the choices made by individuals, institutions, and society in the context of scarcity, which refers to the limited resources available to satisfy unlimited wants. This foundational concept highlights the necessity of making decisions when resources are constrained. In the study of economics, particularly in microeconomics, the focus is on the day-to-day choices made by individuals and businesses. This includes analyzing how price changes influence supply and demand. For instance, if the price of cereal increases, demand may decrease while supply could increase, illustrating the fundamental relationship between price and market behavior.
Additionally, microeconomics delves into the impact of taxes on supply and demand, as well as strategies for maximizing profit across various market structures, such as monopolies and perfect competition. Understanding operational decisions, such as how many laborers to hire and their compensation, is also crucial in this context, as these decisions are made on a smaller scale compared to macroeconomics.
In contrast, macroeconomics examines the economy as a whole, encompassing broader concepts such as national and global economic trends. Key topics include recessions, the factors that lead to economic booms or downturns, inflation, and its effects on interest rates and unemployment. These macroeconomic issues reflect larger systemic dynamics that influence the overall economic landscape, distinguishing them from the more localized focus of microeconomics.
