Economists carry a set of theories in their heads like a carpenter carries around a toolkit. When they see an economic issue or problem, they go through the theories they know to see if they can find one that fits. Then they use the theory to derive insights about the issue or problem.

An economic theory is a set of ideas and principles that outline how different economies function. Depending on their particular role, an economist may employ theories for different purposes. For instance, some theories aim to describe particular economic phenomena, such as inflation or supply and demand, and why they occur. Other economic theories may provide a framework of thought that allows economists to analyze, interpret and predict the behavior of financial markets, industries and governments. Often, though, economists apply theories to the issues or occurrences they observe to glean useful insight, provide explanations and generate potential solutions to problems.Related: Understanding Economics: Definition and Application

1. Supply and demand
Supply and demand is a theory in microeconomics that offers an economic model for price determination. This theory states that the unit price for a good or service may vary until it settles at a point of economic equilibrium, or when the quantity at which consumers demand a good equals the quantity at which a consumer supplies it. For example, as the supply of a good or service decreases and consumer demand persists, the price of it may skyrocket—in this case, the demand is greater than the supply.Read more: Demand: Definition in Economics and 7 Types of Economic Demand
2. Classical economics
Classical economics is an area of thought established by early economists and political thinkers Adam Smith, John Stuart Mill and others. The primary theory of classical economics states that market economies are, by definition, self-regulating systems that are ruled by the laws of production and exchange. With this basis, Smith also introduced the invisible hand, a metaphorical concept and justification for free markets that implies individuals acting within their own self-interests generate social benefits and the public good.
3. Keynesian economics
Keynesian economics consists of multiple macroeconomic theories and models that offer explanations for how aggregate demand—the entirety of an economy's spending—impacts phenomena like economic output and inflation. The central idea of Keynesian thought is that aggregate demand doesn't inherently equate to the productive capacity of an economy, but rather that a variety of factors, both public and private, determine it. With this, Keynesian economical methods support a system in which fluctuations in aggregate demand can lead to changes in employment and output, but not prices.
There's no one specific definition, but most definitions of economic methodology will focus on the methods economists use to study the world and the assumptions they make. Economic methodology also considers the philosophical and ethical underpinnings of economic theory and analysis.
