If you ask a common person about inflation, they will have only complains about it. And then there are these economists and central bankers losing their sleeps on the very low inflation and the potential of deflation. So why is there such a divergence among economists and common people on this?
Nominal vs Real Inflation
Most of the inflation that we experience is nominal and not real and therefore largely an accounting trick and nothing else. Let me explain.
Let’s say – if I earn $10,000 and spend $5000 on food, rent and other essentials, spending almost 50%. Now 10 years from now all these essentials might cost $8000 because prices have increased by around 5% p.a., but if my salary from same job has also increased at 5% p.a., it will still cost me around 50% of my income. So yes, there has been inflation but seems more like an accounting trick than anything else. It costs me same amount of effort to buy same utilities and hence there is no real inflation.
The ultimate finite resource that a human has is: Time. So real inflationary situaion will be if you had to spend more of your time for the same utilities over time. But if you look at the history, we have been able to do more within the same life span. Key reason for this has been continuous advancement in human understanding of the physical universe around us. We call this technological advancement. This has helped us to rearrange the physical universe around us to our benefit, allowing us to do more with less and therefore is a very powerful deflationary force.
So most of the complain we hear on daily basis or the inflation that economists talk about is nominal. This is largely a man-made accounting trick, by-product of the management of one of the greatest tool developed by humans – money. There are some finite resources/assets that we value a lot and therefore have become expensive over time. Think of prime real estate, unique painting of picaso or some other unique prized assets. Also prices for different products and services can move at different rate, and different people will feel different impact from these. But as a whole as long we continue to innovate, world will continue to benefit from real deflation.
Now the question that I have been trying to answer is: whether the nominal inflation is necessary and can one make some reasonable assumption on this for future? I am not sure if I really know enough to answer these yet, but let me share some thoughts on this and how one can think about it especially in the long-term.
I think inflation is a useful tool for economists to manage the economy as it can signal the state of econony. Also as now this is deeply rooted in human psychology, it has huge impact on consumption and investment patterns. Economist strongly agree on the benefits of inflation and fear deflation, so lets just assume its somewhat beneficial without going into details. But again, is this really necessary and especially how much? Is there any way to predict it? If this is man made, why does it get out of control sometime? Why modern developed economies are struggling to keep inflation above 0? My intention is not to be able to forecast it, but having a better understanding of this and have a framework to think about if/when things change in future.
In some of my next posts, I want to explore these questions and share my thoughts on this. It has helped me to think more clearly about the the function of money, value of real assets and how all of this affects the modern economy! Of course ultimately my quest is to improve my investment process and I think this can have significant implications on that.
