negative interest rate lending ripple effects I was attempt to describe the ramifications of negative interest rates across benchmarks.

I can foresee the business practice changes amongst holders of government bonds, savings accounts, certificates of deposit and mortgages. My conclusion was a possible stall of lending in those markets, but thats a red herring to my real question. When it comes to corporate debt I wasn't so sure what ramification even lower interest rates would have on the attractiveness of investment grade corporate debt.

Is there anywhere I can read prevailing or new theories about that?
Decreasing the nominal interest rate to a negative value will cause businesses to have to raise their prices in order to maintain 0 economic profit. This is because wages are "sticky," and cannot change in a general quarterly or annual period.  People who live in the country have not been given any higher incentive to spend, but since prices are increased - aggregate demand will decrease.  Additionally, in order to survive the cut in demand and rise in prices, firms will look to lay off workers - raising unemployment.  Consumption should decrease as a result of a negative interest rate charged by the Central Bank.  In what was an attempt to increase GDP - output will decrease.  --> Stagflation is likely to occur
