Demand in the context of "Need"

In economics, inflation is an increase in the average price of goods and services in terms of money. This increase is measured using a price index, typically a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index.

Changes in inflation are widely attributed to fluctuations in real demand for goods and services (also known as demand shocks, including changes in fiscal or monetary policy), changes in available supplies such as during energy crises (also known as supply shocks), or changes in inflation expectations, which may be self-fulfilling. Moderate inflation affects economies in both positive and negative ways. The negative effects would include an increase in the opportunity cost of holding money; uncertainty over future inflation, which may discourage investment and savings; and, if inflation were rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include reducing unemployment due to nominal wage rigidity, allowing the central bank greater freedom in carrying out monetary policy, encouraging loans and investment instead of money hoarding, and avoiding the inefficiencies associated with deflation.

In economics, competition is a scenario where different economic firms are in contention to obtain goods that are limited by varying the elements of the marketing mix: price, product, promotion and place. In classical economic thought, competition causes commercial firms to develop new products, services and technologies, which would give consumers greater selection and better products. The greater the selection of a good is in the market, the lower prices for the products typically are, compared to what the price would be if there was no competition (monopoly) or little competition (oligopoly).

The level of competition that exists within the market is dependent on a variety of factors both on the firm/ seller side; the number of firms, barriers to entry, information, and availability/ accessibility of resources. The number of buyers within the market also factors into competition with each buyer having a willingness to pay, influencing overall demand for the product in the market.

The New Deal was a series of wide-reaching economic, social, and political reforms enacted by President Franklin D. Roosevelt in the United States between 1933 and 1938, in response to the Great Depression, which had started in 1929. Roosevelt introduced the phrase upon accepting the Democratic Party's presidential nomination in 1932 before winning the election in a landslide over incumbent Herbert Hoover, whose administration was viewed by many as doing too little to help those affected. Roosevelt believed that the depression was caused by inherent market instability and too little demand per the Keynesian model of economics and that massive government intervention was necessary to stabilize and rationalize the economy.

During Roosevelt's first hundred days in office in 1933 until 1935, FDR introduced what historians refer to as the "First New Deal", which focused on the "3 R's": relief for the unemployed and for the poor, recovery of the economy back to normal levels, and reforms of the financial system to prevent a repeat depression. Roosevelt signed the Emergency Banking Act, which authorized the Federal Reserve to insure deposits to restore confidence, and the 1933 Banking Act made this permanent with the Federal Deposit Insurance Corporation (FDIC). Other laws created the National Recovery Administration (NRA), which allowed industries to create "codes of fair competition"; the Securities and Exchange Commission (SEC), which protected investors from abusive stock market practices; and the Agricultural Adjustment Administration (AAA), which raised rural incomes by controlling production. Public works were undertaken in order to find jobs for the unemployed (25 percent of the workforce when Roosevelt took office): the Civilian Conservation Corps (CCC) enlisted young men for manual labor on government land, and the Tennessee Valley Authority (TVA) promoted electricity generation and other forms of economic development in the drainage basin of the Tennessee River.

A price is the (usually not negative) quantity of payment or compensation expected, required, or given by one party to another in return for goods or services. In some situations, especially when the product is a service rather than a physical good, the price for the service may be called something else such as "rent" or "tuition". Prices are influenced by production costs, supply of the desired product, and demand for the product. A price may be determined by a monopolist or may be imposed on the firm by market conditions.

Price can be quoted in currency, quantities of goods or vouchers.

In economics, a demand shock is a sudden event that increases or decreases demand for goods or services temporarily.

A positive demand shock increases aggregate demand (AD) and a negative demand shock decreases aggregate demand. Prices of goods and services are affected in both cases. When demand for goods or services increases, its price (or price levels) increases because of a shift in the demand curve to the right. When demand decreases, its price decreases because of a shift in the demand curve to the left. Demand shocks can originate from changes in things such as tax rates, money supply, and government spending. For example, taxpayers owe the government less money after a tax cut, thereby freeing up more money available for personal spending. When the taxpayers use the money to purchase goods and services, their prices go up.

Industrial production is a measure of output of the industrial sector of the economy. The industrial sector includes manufacturing, mining, and utilities. Although these sectors contribute only a small portion of gross domestic product (GDP), they are highly sensitive to interest rates and consumer demand. This makes industrial production an important tool for forecasting future GDP and economic performance. Industrial production figures are also used by central banks to measure inflation, as high levels of industrial production can lead to uncontrolled levels of consumption and rapid inflation .

In microeconomics, a monopoly price is set by a monopoly. A monopoly occurs when a firm lacks any viable competition and is the sole producer of the industry's product. Because a monopoly faces no competition, it has absolute market power and can set a price above the firm's marginal cost.

The monopoly ensures a monopoly price exists when it establishes the quantity of the product. As the sole supplier of the product within the market, its sales establish the entire industry's supply within the market, and the monopoly's production and sales decisions can establish a single price for the industry without any influence from competing firms. The monopoly always considers the demand for its product as it considers what price is appropriate, such that it chooses a production supply and price combination that ensures a maximum economic profit, which is determined by ensuring that the marginal cost (determined by the firm's technical limitations that form its cost structure) is the same as the marginal revenue (MR) (as determined by the impact a change in the price of the product will impact the quantity demanded) at the quantity it decides to sell. The marginal revenue is solely determined by the demand for the product within the industry and is the change in revenue that will occur by lowering the price just enough to ensure a single additional unit is sold. The marginal revenue is positive, but it is lower than its associated price because lowering the price will increase the demand for its product and increase the firm's sales revenue, and lower the price paid by those who are willing to buy the product at the higher price, which ensures a lower sales revenue on the product sales than those willing to pay the higher price.
