Though many economists seem to agree that secular price deflation (that is falling prices without monetary deflation) isn’t a bad thing, most also agree that monetary deflation is awful, since not only do prices fall, but wages and profits fall as well. This is conceived as negative since the real value of debt increases, making it harder for debtors to pay back their creditors. Thus, monetary deflation is perceived to harm both debtors and creditors.
I increasingly disagree with the above. If individuals come to expect deflation, I believe that this deflation could play a positive role. In a world where deflation is expected, firms could still be profitable, since they would modify their behavior in order to continue being profitable in a deflationary environment. Being profit-seeking institutions, they would continue to accumulate capital and invest in R&D, thereby increasing labor productivity. This increase in labor productivity would mean one crucial thing - the fall in prices would exceed the fall in wages and profitability. Thus, though wages and profits would fall while the real value of debt would rise, the greater fall in prices could offset the increasing real value of debt.
So assuming a rather drastic deflation rate of 10% per year, the real value of debt would increase by 10% while nominal wages and profits would fall by 10%. At the same time, prices would fall by more than 10% (assuming normal GDP growth rates, prices would fall by approx. 12-13%). So any deflation would ultimately make the increasing real value of debt moot.
I think there could be very positive side effects that expected monetary deflation could have: households and firms would run very sound balance sheets and real saving/investment would increase. Monetary deflation would obviously create an incentive to save money and a disincentive to borrow (“dissave”) money. This would push households and firms to become more dependent on their own resources (saved income) over the resources of others (borrowed income). This increase in net saving would directly or indirectly increase real investment, by pushing interest rates lower and freeing up resources for investment use.
Now, I’m not saying that monetary deflation is a policy arraignment that the government or its central banks should seek. Instead, I believe that a free market currency system ought to determine the supply of money. But at the same time I believe that the dangers of monetary deflation are widely exaggerated.
