The 5 Major Changes in the PPC Landscape

The PPC, or the price-performance curve, is a graphical representation of the relationship between price and performance. The five shifters of the PPC are: 1) Price 2) Performance 3) Technology 4) Quality 5) Quantity.

1) Price: The most obvious factor that affects the PPC is price. As prices increase, performance usually decreases and vice versa. This is because manufacturers often have to make trade-offs between price and performance in order to stay competitive. For example, a company might choose to use lower quality components in order to keep costs down.

2) Performance: Another important factor that affects the PPC is performance. In general, as performance increases so does price. This is because higher performing products usually require more expensive components and technology. For example, a high-end graphics card will typically cost more than a lower end model even though they may only offer slightly better performance.

3) Technology: As new technologies are developed, they often allow for increased performance at lower prices. This is because older technologies become less expensive as they become more commonplace while newer technologies are initially only available to early adopters who are willing to pay a premium for them. For example, SSDs were once very expensive but their.

Change in Taste and Preference

Taste and preference are important factors in purchasing decisions. They can be shaped by a variety of influences, including advertising, personal experiences and peer pressure.

Tastes can change over time as people are exposed to new things or have new experiences. For example, someone who once disliked the taste of beer may develop a taste for it after trying different types or brands.

Preferences can also be affected by changes in lifestyle or circumstances. A person who prefers expensive wines may start buying cheaper brands if their income decreases.

Some people are more influenced by changes in taste and preference than others. Those who are less influenced tend to have stronger preferences and are less likely to change them.

Price of Related Goods

A change in the price of a good can lead to a change in demand for that good. An increase in the price of a good will lead to a decrease in demand for that good, while a decrease in the price of a good will lead to an increase in demand for that good. The relationship between price and quantity demanded is known as the law of demand.

The law of demand is based on the premise that, all else being equal, consumers will purchase more of a good when its price is lower and less of a good when its price is higher. The law of demand exists because people have limited incomes and must make choices about how to spend their money. When the prices.


There are several different ways to measure income. The most common is household income, which measures the total income of all members of a household. Household income can be measured before or after taxes and includes all sources of income, such as wages, investments, and government benefits.

Another way to measure income is per capita income, which divides the total national income by the population size. This measure gives a more accurate picture of average incomes than household income because it takes into account households of different sizes. Finally, median household income is the point at which half of households have less income and half have more. This measure is often used to gauge whether incomes are increasing or decreasing over time because it is not affected by changes in household size or composition.

Income inequality refers to the extent to which there is unequal distribution of income among individuals or households in an economy. It can be measured using various methods, including the Gini coefficient and Theil index. A high level of inequality means that there are large differences in incomes between individuals or households; a low level of inequality means that incomes are relatively equal.
