Individuals, firms, markets and market failure revision notes
Individuals:
Individuals refer to people who participate in an economy as consumers, producers, or
workers. They make decisions about what to buy, what to sell, and how to allocate their
time and resources.
Firms:
Firms are businesses that produce and sell goods and services. They are a key part of any
economy and play a crucial role in the allocation of resources. Firms can be small, medium,
or large, and can operate in the private or public sector.
Markets:
Markets are a place where buyers and sellers interact to exchange goods and services.
There are different types of markets, including goods markets (e.g. a grocery store), financial
markets (e.g. a stock exchange), and labour markets (e.g. a job fair). Markets play a key role
in determining the price and quantity of goods and services produced and consumed.
Market failure:
Market failure occurs when the market system fails to allocate resources efficiently. This can
happen for a variety of reasons, including externalities (e.g. pollution), information
asymmetry (e.g. lack of transparency), and public goods (e.g. national defence). Market
failure can lead to inefficient outcomes, such as overproduction or underproduction of
certain goods, and can be addressed through government intervention, such as taxes or
regulations.
Individuals in more detail:
Individuals are people who participate in an economy as consumers, producers, or workers.
As consumers, individuals make decisions about what to buy and how much to buy based on
their preferences, income, and the prices of the goods and services available to them. As
producers, individuals make decisions about what to produce, how much to produce, and
how to produce it based on their resources, technology, and the prices they can charge for
their goods and services. As workers, individuals make decisions about how much time to
allocate to work and what type of work to do based on their skills, education, and the wages
and working conditions available to them.
Individuals are influenced by a variety of factors in their economic decision-making,
including their values, culture, and environment. They may also be influenced by economic
policies and institutions, such as tax policies, monetary policy, and trade policies.
Individuals are a crucial part of any economy, and their decisions help to shape the overall
direction and performance of the economy.
