Economists have developed models including variables that could affect a particular outcome, but have failed to include the uncertainty which could change the results… The Black Swan, the most improbable or uncertain events and the Gray Rhino, the most probable or certain events that could affect the outcome of the dependent variable… The objective or goal of a model is to identify, though the Black Swan events are difficult to gauge, and the Gray Rhino events to include them in the models to predict the effects on the growth…
The Cov-19 is an example of the Black Swan event which no one could foresee so that a preemptive or proactive action could be engineered which pushed the economies under slow economic activity and high unemployment and low productivity, it was a hit on the both demand and supply and ultimately on growth, globally. In the developed economies which have a good productivity and supply levels but low demand saw a plunge in the inflation or price level, but emerging economies that have low unemployment and productivity and supply, but high demand witnessed surge in inflation…
Nonetheless, post active action and monetary stimulus and vaccination helped only a slow recovery from the pandemic and slowdown. The developed countries provided a bigger stimulus to increase demand and zero interest rates to incite recovery where demand side was a problem than the weak supply side and high demand in the emerging markets like INDIA where the stimulus have staged with a delay. The stimulus in the developed countries has increased demand and price expectations in the economy and in the emerging markets it has increased supply and lower price expectations.
In the US low inflation is a problem for wagers and for the business also their income is not going up and in the emerging economies like INDIA high inflation is a problem, nevertheless the objective is to keep prices stable – interest rate, wages and exchange rate - since lower price expectations during slowdown delay demand and reinforce lower prices and higher price expectations during high growth delay supply and reinforce higher prices. Too much high demand and low supply increases nominal prices or inflation which increase spending, and too much high supply and low demand lower real prices or inflation which could increase spending, too.
Both, lower prices and higher prices are good, but within limits, because lower prices increase demand when supply is high to stabilise prices and achieve full-employment and higher price increase supply when demand is high for the price stability and full employment. In the West we have high supply and low demand and in the emerging world we have high demand and low supply which is needed to balance to stabilise the inflation or price level. Instead of bringing supply down to demand the West may increase demand on par with supply to increase growth and instead of bringing demand down to supply the emerging nations may increase supply upto demand to keep prices stable and gain full employment and growth. Globally, too, the higher supply must keep flowing from the West to the emerging world to keep stability through higher trade and reduce inequality.
The objective is to keep demand and supply and prices stable at full employment – maintaining stable and predictable prices and growth regime for the interest rate, wages and exchange rate, actually real interest rate, real wages and exchange rate…
