Understanding Macroeconomics: GDP, and Inflation
Given the enormous scale of government budgets and the impact of economic
policy on consumers and businesses, macroeconomics clearly concerns itself
with significant issues. Properly applied, economic theories can offer
illuminating insights on how economies function and the long-term
consequences of particular policies and decisions. Macroeconomic theory can
also help individual businesses and investors make better decisions through a
more thorough understanding of the effects of broad economic trends and
policies on their own industries.
Limits of Macroeconomics
It is also important to understand the limitations of economic theory. Theories
are often created in a vacuum and lack certain real-world details like taxation,
regulation, and transaction costs. The real world is also decidedly complicated
and includes matters of social preference and conscience that do not lend
themselves to mathematical analysis.
Even with the limits of economic theory, it is important and worthwhile to follow
the major macroeconomic indicators like GDP, inflation, and unemployment.
The performance of companies, and by extension their stocks, is significantly
influenced by the economic conditions in which the companies operate and
the study of macroeconomic statistics can help an investor make better
decisions and spot turning points.
Economic Growth
Economic growth refers to an increase in aggregate production in an
economy. Macroeconomists try to understand the factors that either promote
or retard economic growth in order to support economic policies that will
support development, progress, and rising living standards.
Adam Smith's classic 18th-century work, An Inquiry into the Nature and
Causes of the Wealth of Nations, which advocated free trade, laissez-faire
economic policy, and expanding the division of labor, was arguably the first,
and certainly one of the seminal works in this body of research. By the 20th
century, macroeconomists began to study growth with more formal
mathematical models. Growth is commonly modeled as a function of physical
capital, human capital, labor force, and technology.
