Microeconomics Quiz

Microeconomics: Analyzing the Behavior of Individuals and Firms

• Microeconomics studies the behavior of individuals and firms in making decisions regarding the allocation of scarce resources and the interactions among these individuals and firms.

• Microeconomics focuses on the study of individual markets, sectors, or industries, as opposed to the national economy as a whole.

• One goal of microeconomics is to analyze the market mechanisms that establish relative prices among goods and services and allocate limited resources among alternative uses.

• Microeconomics shows conditions under which free markets lead to desirable allocations and analyzes market failure, where markets fail to produce efficient results.

• Microeconomics deals with the effects of economic policies on microeconomic behavior and thus on growth, inflation, and unemployment.

• Microeconomic theory typically begins with the study of a single rational and utility maximizing individual, with stable preferences that are both complete and transitive.

• The utility maximization problem is a constrained optimization problem in which an individual seeks to maximize utility subject to a budget constraint.

• The theory of supply and demand usually assumes that markets are perfectly competitive, but in many real-life transactions, the assumption fails because some individual buyers or sellers have the ability to influence prices.

• Mainstream economics does not assume a priori that markets are preferable to other forms of social organization and much analysis is devoted to cases where market failures lead to suboptimal resource allocation.

• Opportunity cost is closely related to the idea of time constraints, where the opportunity cost of any activity is the value of the next-best alternative thing one may have done instead.

• Price theory is a field of economics that uses the supply and demand framework to explain and predict human behavior, focusing on how agents respond to prices.

• Supply and demand is an economic model of price determination in a perfectly competitive market, where the unit price for a particular good is the price at which the quantity demanded by consumers equals the quantity supplied by producers.Microeconomics: Understanding the Market System

• The law of demand states that, in general, price and quantity demanded in a given market are inversely related. That is, the higher the price of a product, the less of it people would be prepared to buy (other things unchanged). As the price of a good goes down, consumers will demand more of it.

• The "Law of Supply" states that, in general, a rise in price leads to an expansion in supply and a fall in price leads to a contraction in supply.

• Market equilibrium occurs where quantity supplied equals quantity demanded, the intersection of the supply and demand curves. At a price below equilibrium, there is a shortage of quantity supplied compared to quantity demanded. At a price above equilibrium, there is a surplus of quantity supplied compared to quantity demanded.

• On the supply side of the market, some factors of production are described as (relatively) variable in the short run, which affects the cost of changing output levels. Their usage rates can be changed easily, such as electrical power, raw-material inputs, and over-time and temp work.

• Marginalist theory describes the consumers as attempting to reach most-preferred positions, subject to income and wealth constraints while producers attempt to maximize profits subject to their constraints, including demand for goods produced, technology, and the price of inputs.

• Demand-and-supply analysis is used to explain the behavior of perfectly competitive markets, but as a standard of comparison, it can be extended to any type of market.

• Market structure refers to features of a market, including the number of firms in the market, the distribution of market shares between them, product uniformity across firms, how easy it is for firms to enter and exit the market, and forms of competition in the market.

• Perfect competition is a situation in which numerous small firms producing identical products compete against each other in a given industry.

• Imperfect competition is a type of market structure showing some but not all features of competitive markets.

• A monopoly is a market structure in which a market or industry is dominated by a single supplier of a particular good or service.

• An oligopoly is a market structure in which a market or industry is dominated by a small number of firms (oligopolists).

• Game theory is a major method used in mathematical economics and business for modeling competing behaviors of interacting agents.

• Information economics is a branch of microeconomic theory that studies how information and information systems affect an economy and economic decisions.
