A Matter of Choice
All microeconomics is built on the idea that producers and consumers choose what to make or what to buy. As a result, economists tend to have a healthy respect for choice itself. People value things in different ways; Microeconomists want to look at the consequences of, rather than the reasons for, those values.
Creativity is the Solution
Trade is possible because people value things differently. The desire to trade creates the need for a means to trade things — a market.
In several situations, a market has difficulty pricing a good. Public goods — such as street lighting, public parks, or even law enforcement — are a case, one made worse by the impossibility of excluding people who have not paid for these services from using them.
When people come up against an unfavorable economic situation, they try to find solutions to get around the problem. Microeconomists have great respect for this creativity; they want to see what can be achieved before coming up with ways to intervene.
Competing on Price or Quality
In a perfectly competitive market, competition is only ever on price, which is always forced down to the marginal cost of production for the marginal firm.
In monopolistic competition — a common market structure — the alternative is to change your focus and try to make your product different or distinctive from the other competitors and make profits. However, you need to invest and use resources that you could have spent on getting costs down. Hence, firms tend to choose either to be the lowest-cost competitor or a high-quality competitor.
A Starting Point for Comparison
Markets have unique and distinctive features that often vary from place to place and product to product, for example, in healthcare. Microeconomists explore the differences between such kinds of markets and more generic ones. Sometimes they propose ways to make such markets more efficient, but they often analyze those features very carefully to understand their creation and evolution.
Tradeoff - A Fact of Life
The economist’s model of consumer behavior is called a constrained optimization. As long as things are scarce, you have to make choices. To a Microeconomist, getting your best level of utility is always about trading off one thing for another; this is just a fact of life.
The Next Best Thing
The Theory of the Second Best is a reminder that if you cannot get the optimal solution, there may be second-best alternatives. Microeconomists recommend that you look carefully at the inefficiency and the external cost in this situation before coming up with a solution.
The Key Question
Even though economists generally prefer free exchange — and therefore markets — to achieve goals, using those markets is not always cost-free. Sometimes, an unaccounted cost falls upon another person — an external cost — and sometimes there are costs associated with just finding the person to trade with — transactions costs.
To a Microeconomist, the key question is what makes those costs as low as possible? They recommend that entrepreneurs must think carefully about where the inevitable costs of using a market fall while seeking out the opportunities that reduce transaction costs for buyers and sellers.
Competition - Two Sides of the Coin
When the market is not perfectly competitive, incumbent firms get a bigger share of trade gains. They have a vested interest in preventing another firm from coming in and competing for a share of the profits. They may advertise or invest in things that involve sunk cost to prevent a rival.
Consumers lose out because the incumbent producers produce less, for a higher cost, and take more of the surplus. Microeconomists look carefully at barriers to market entry and work to get them down as low as possible in the long run.
But that isn’t the whole story.
There are times when economists give two cheers to markets that are not competitive. For example, a monopolist doesn’t compete with itself, which can mean that you can get a better range of product diversity when there is less competition. Optimization of Optimism Economics often gets a bad rap because the model of people and firms seems to prioritize individual benefit without focusing on many of the features people deem essential. Microeconomists are the world’s greatest optimists. They build economic models on the assumption that people follow their interests and, in so doing, create firms, organizations, production and consumption, and all the things that make the world go round.
Econometrics
Econometrics analyzes data using statistical methods to test or develop economic theory. These methods rely on statistical inferences to quantify and analyze economic theories by leveraging frequency distributions, probability, probability distributions, statistical inference, correlation analysis, simple and multiple regression analysis, simultaneous equations models, and time series methods.
Government Jobs - the Pros & Cons
Government jobs are generally very secure and tend to benefit from excellent health care coverage and plenty of vacation days. However, Microeconomists must remember that working within the government can be frustrating due to the slow pace and the difficulties of getting different stakeholders to agree on a policy. It requires patience, expertise at explaining complicated economic issues to non-experts, and the willingness to work alongside people of different political beliefs and values.
