economists need different models of the economy because

Those benign numbers miss mass layoffs announced by restaurants, retailers, manufacturers and others because they occurred in the second half of March, after the survey period.Possible outcomes for the March report are unusually wide.
But given the current situation, you can see why companies might need to take a step back from shoveling cash out the door. For example, an economist might try to explain what caused the Great Recession in 2008, or she might try to predict how a personal income tax cut would affect automobile purchases. Economists reach for theories in much the same way as a carpenter might grab a tool. You can get away with fuzzy thinking and vague approximations in your own mind, but not when you’re reducing a model to algebraic equations. Richard Henderson at the Financial Times writes this morning about Dividends are a marker of financial stability for listed companies that try to raise payouts year after year, and which are typically penalised by investors when they fail to do so. That said, math is a tool that can be used to explore economic concepts in very helpful ways. Some expect the unemployment rate to hold at a 50-year low, others project it will rise above 5%.“No forecasting models are built to deal with the unique situation we have,” said Brad Hershbein, an economist at the Upjohn Institute for Employment Research.

At the same time, math has certain disadvantages. Both micro and macroeconomics are explained in terms of theories and models. Why would you use your fist to bang a nail, if you had a hammer? No model and no gut is up to the challenge of evaluating exactly what is going on. So the “March” employment data really represents mid-February to mid-March. Normally, that discrepancy would only be discussed by a bunch of econometricians in a grad seminar, but given the gargantuan changes in the economy these days, that artifact of survey design is suddenly front and center.Economists surveyed by The Wall Street Journal through Monday forecast employers cut 10,000 workers from payrolls and the unemployment rate for March ticked up to 3.7% from 3.5%. Importance of Models in Economics Suttinee Kaewsuwan BBA 2 SS 2002 - 3 - Types of Models in Economics From the definition of a model, it has been said that models in economics have the wide range of forms including graphs, diagrams, and mathematical models. Economics (/ ɛ k ə ˈ n ɒ m ɪ k s, iː k ə-/) is the social science that studies the production, distribution, and consumption of goods and services.. Economics focuses on the behaviour and interactions of economic agents and how economies work. It disciplines our thinking by making us specify exactly what we mean. The circular flow diagram simplifies these distinctions in order to make the picture easier to grasp.
Similarly, using the algebraic formula for a line allows economists to find precise points on a graphs that help in interpreting how much of a good should be sold, or at what price.An architect who is designing a major office building will probably build a physical model that sits on a tabletop to show how the entire city block will look after the new building is constructed.

Sometimes economists use the term Watch this video to get a better grasp on economic models and why they are useful to economists in making predictions about behavior.Economists use models as the primary tool for explaining or making predictions about economic issues and problems. Surveyed economists are forecasting a range of employers adding 312,000 jobs to shedding 1.25 million. While there are a variety of scenarios that are reasonable, those scenarios are often so incompatible that it creates analysis paralysis.Will travel pick up in two years due to pent-up demand, or will we see a long-term secular decline in exploring the world? Models in economics also help us to generate hypotheses about the real world. The point is that math is one tool, but it’s not the only tool or even always the best tool economists can use to work with economic models. For example, if a business puts their product on sale for 10% off the regular price, how much more will consumers buy? The most well-known theories are probably those of supply and demand, but you will learn about several others.Why would an economist use math when there are other ways of representing models, such as with text or narrative?
