Many economists and financial speculators were surprised when the U.S. economy didn't experience significant inflation following the inflow of "money" generated by the U.S. financial system and other world banks following the economic problems in the years 2007 and 2008.
As we experience another year during which the U.S. Federal Reserve system used its fiscal powers to increase the flow of money in the economy, analysts again are concerned about the specter of inflation.
We are right to be concerned about the risk of inflation, but I don't think we need to be concerned about inflation as much as we were in the 1970's and 1980's for one simple reason. That reason is that our technology is keeping inflation from happening. And by "technology" I mean the information, knowledge, and automation of accounting processes we enjoy as part of the computer and information ages.
Inflation occurs when demand for a product exceeds supply. This rarely happens anymore because businesses are so good at forecasting demand. Businesses strive fervently to produce enough product to meet demand but also to avoid overproducing and causing excess inventory of product they can't sell. Therefore they have invested heavily in computer systems connected to the Internet to provide good models based on forecasts of the exact demand for product expected in different areas of the world based on hundreds of factors.
How can Amazon deliver those protein bars you ordered in the morning to your home within hours? It is because they have forecast that there will be a certain about of demand for those protein bars in your geographic area and have provided just enough supply of those protein bars at their local warehouse to meet that demand. They are not tracking what specific people want; they are tracking the statistical averages. They also know how to factor in the impact of weather, festivals, sporting events, and concerts into the impact on demand in specific areas and stock their warehouses accordingly.
Amazon does this really well, but Walmart does also; as do thousands of other businesses. This means that inadequate supply is not as likely as before the computer age. It is only when the raw material is in short supply that we are our economy will be unable to meet current demand; such as when the packing plants shut down and we can't get beef to supermarkets; that we have cases where supply fails to meet demand. And these cases are temporary. People don't fear that they will go on for years.
Due to better access to information and our ability to forecast future demand, we are much more likely to meet demand in the future and thus less likely to face situations where supply systemically fails to keep up with demand causing long periods of inflation.
