The Difference Between Inflation, Deflation, and Disinflation
The Difference Between Inflation, Deflation, and Disinflation
Inflation is a general increase in the price level. The price level represents the prices of most products in an economy. Thus, the prices of most products are increasing during periods of inflation. The forces of supply and demand still determine prices in individual markets. Yet, inflation creates a tendency for prices to rise throughout the economy.
The inflation rate measures how quickly the price level changes. It is usually reported on an annual basis. In October 2003, for example, the inflation rate was 2.04%. This means that if prices rose at this same rate for an entire year, then they would be 2.04% higher on October 1, 2004 than they were on October 1, 2003. (The price index was actually 0.17% higher on October 31, 2003 than it was on October 1, 2003. Twelve months multiplied by 0.17% yields an annual rate of 2.04% per year.)
Deflation is a general decrease in the price level. During periods of deflation, the prices of most products are decreasing. Deflation is undesirable because it usually causes a significant decrease in overall spending (i.e., aggregate demand) in an economy and is most likely to occur when the economy is already stagnant. For example, deflation occurred in the United States during the Great Depression. Deflation occurs when the inflation rate is negative.
Disinflation occurs when the inflation rate decreases, but remains positive. For example, if the inflation rate changes from 6% in January to 5.5% in February to 5.2% in March, economists would say there is disinflation in the economy during the first quarter of the year (i.e., during January, February and March).

Deletethank you
ReplyDeleteI could not have closed on my first home without Mr, Benjamin Lee ! Benjamin and his team went above and beyond for me on this transaction. He handled my very tight turn around time with ease and was always available for me when I had questions (and I had plenty), even when he was away from the office, which I greatly appreciated! He and his team handled many last-minute scrambles with the seller and worked tirelessly to make sure that I could close before my lease (and my down payment assistance, for that matter) expired. Mr Benjamin is an incredibly knowledgeable Loan Officer, courteous, and patient. I went through a couple offers on properties before my final purchase and Benjamin was there to help with each one, often coordinating with my agent behind the scenes. I felt supported throughout the entire process. Thanks to Benjamin and the tireless efforts of his team, I am now a proud homeowner! I would encourage you to consider Benjamin Briel Lee for any kind of loan.Mr, Benjamin Lee Contact informations.via WhatsApp +1-989-394-3740 Email- 247officedept@gmail.com.
