Demand shock refers to sudden changes in demand for a product or property purchase due to factors such as supply-demand mismatch, tax laws, and media coverage. Underproduction causes a positive shock, while overproduction causes a negative shock. Tax laws can manipulate output levels, and media coverage can impact purchasing decisions.
Demand shock is an economic term that refers to sudden changes in the level of demand for a certain product or property purchase. These events can result from a number of factors. They could include a mismatch between the level of public desire for an item versus the available supply, changes in tax laws, and the funding available if the costs of the goods exceed most people’s ability to purchase the item for cash. Another potential trigger for the demand shock could be media coverage that stimulates public desire for an item.
The term “demand level” describes the correlation between product availability and the number of consumers who want the product, have the ability to buy it, and intend to buy it soon. All three factors are typically involved in triggering a demand shock. For example, millions of people may want to purchase a new technological gadget and may also have the ability to purchase the item. If most wait to buy it during a particular season, such as a major holiday, a demand shock is likely to occur. Without the added factor of a gift-giving season, demand would likely be more evenly distributed over a period of time.
The factors that trigger a demand shock vary widely and are not always predictable, as in the case of a fad. For example, if a popular new toy captures consumers’ attention and the desire to own the product becomes intense, the demand for the product will rise sharply, producing a sudden upward swing in the demand curve. When demand is plotted against supply on a two-dimensional graph, it produces a line that can be straight or curved, which is the origin of the term “demand curve.”
One of the main causes of a demand curve is when the planned production of an item does not match public demand over a given period of time. Underproduction of an item can cause a positive demand shock, while overproduction can cause a negative demand shock. Both present difficulties for producers. The former usually results in missed opportunities to sell a product when consumer desires are strong. In the second circumstance, manufacturers have to overpay to store or liquidate unsold inventory.
Changes in tax laws can be used to manipulate output levels, particularly if there is a negative demand shock. For example, if too many homes are erected in a speculative real estate frenzy, as occurred during the US subprime mortgage crisis of the mid-to-late 2000s, lawmakers can pass laws granting tax incentives to correct the imbalance. Luxury items may be taxed at higher rates during times of prosperity, as raising taxes during those times typically won’t have a negative impact on sales. Media coverage can also have a major impact on demand shocks, as consumers receive feedback from media stories and often incorporate that information into purchasing decisions.
