(NBER): "...a significant decline in economic activity spread across the country, lasting more than a few months, normally visible in real GDP growth, real personal income, employment (non-farm payrolls), industrial production, and wholesale-retail sales."

Labor economists categorize people into three groups: "employed" - actually working at a job, even if part-time; "unemployed" - not working, but looking for work or awaiting a scheduled recall from a temporary layoff; and "not in the labor force" - neither working nor looking for work. People not in the labor force, even if they have given up looking for a job despite wanting one, are not considered unemployed. For this reason it is often thought, especially when a recession has persisted for a sustained period, that the unemployment rate understates the true amount of unemployment because some unemployment is disguised by discouraged workers having left the labor force.

Supply is a schedule that shows the relationship between the good’s price and quantity supplied, holding everything else constant. Holding everything else constant seems a little ambitious, even for economists, but there is a reason for that qualification. By holding everything else constant, supply enables you to focus on the relationship between price and the quantity provided. You must be able to distinguish between two terms that sound the same, quantity supplied and supply, but mean very different things. It is common for others not to make the distinction and as a result their analysis is confused. Quantity supplied refers to the amount of the good businesses provide at a specific price. Economists use the term supply to refer to the entire curve. The supply curve is an equation or line on a graph showing the different quantities provided at every possible price.

Say's Law and Supply Side Economics. It should be known that at the beginning of a dynasty, taxation yields a large revenue from small assessments. It is drawn with price on the vertical axis of the graph and quantity demanded on the horizontal axis. With few exceptions, the demand curve is delineated as sloping downward from left to right because price and quantity demanded are inversely related (i.e., the lower the price of a product, the higher the demand or number of sales). This relationship is contingent on certain (other things equal) conditions remaining constant. Such conditions include the number of consumers in the market, consumer tastes or preferences, prices of substitute goods, consumer price expectations, and personal income. A change in one or more of these conditions causes a change in demand, which is reflected by a shift in the location of the demand curve.

The total demand for a product will depend on a number of factors, with the most obvious factor being the price of the product. A rational consumer will seek to purchase products at the lowest price possible because it maximises the 'value' or 'satisfaction' in economics we sometimes refer to this as utility he or she gets.

Estimated Economic Impact of Illegal Opioid Use and Opioid-Related Overdose Deaths The White House Council of Economic Advisers [CEA] released its analysis of the economic costs of illegal opioid use, related overdoses, and overdose mortality in November 2017. ONDCP changed its method of accounting for treatment spending in its FY2018 report. 18, in the FY2018 budget report: "The estimates for the CMS [Centers or Medicare and Medicaid Services] reflect Medicaid and Medicare benefit outlays (excluding spending under Medicare Part D) for substance use disorder treatment; they do not reflect budget authority.

Within this total, the Budget supports \$1.3 billion in investments authorized by the Comprehensive Addiction and Recovery Act (CARA) the 21st Century Cures Act, and other opioid-specific programs to help address the opioid epidemic." "National Drug Control Budget: FY 2018 Funding Highlights" (Washington, DC: Executive Office of the President, Office of National Drug Control Policy), May 2017, p.

According to the CEA, "We diverge from the previous literature by quantifying the costs of opioid-related overdose deaths based on economic valuations of fatality risk reduction, the “value of a statistical life” (VSL)." The CEA noted that "According to a recent white paper prepared by the U. Environmental Protection Agency’s (EPA) Office of Policy for review by the EPA’s Science Advisory Board (U. EPA 2016), the EPA’s current guidance calls for using a VSL estimate of \$10.1 million (in 2015 dollars), updated from earlier estimates based on inflation, income growth, and assumed income elasticities. The central estimates used by these three agencies, DOT, EPA, and HHS, range from a low of \$9.4 million (HHS) to a high of \$10.1 million (EPA) (in 2015 dollars)." In addition, the CEA assumed that the number of opioid-related overdoses in the US in 2015 was significantly under-reported.

## Law of demand - Wikipedia

In microeconomics, the law of demand states that, "conditional on all else being equal, as the price of a good increases ↑, quantity demanded decreases ↓; conversely, as the price of a good decreases ↓, quantity demanded increases ↑". In other words, the law of demand describes an inverse relationship between. Increases in demand are shown by a shift to the right in the demand curve. This could be caused by a number of factors, including a rise in income, a rise in the price of a substitute or a fall in the price of a complement. A shift in demand to the right means an increase in the quantity demanded at every price. For example, demand can decrease and cause a shift to the left of the demand curve for a number of reasons, including a fall in income, assuming a good is a normal good, a fall in the price of a substitute and a rise in the price of a complement.
