Quote from seasideheights:
Good find.
The summary of andy9775's posted paper is worth noting
"The Government of Indiaâs proposed transaction tax on commodity
futures trading is likely harmful to Indiaâs economy. This report illustrates
the experience around the world (New York, Japan, Taiwan, etc.) which
shows conclusively that transaction taxes in financial markets hurt local
economies. Typically, these taxes adversely impact markets liquidity,
impair the price discovery function, cause a significant loss of trading
volume to competing overseas exchanges or to underground activity,
and secure no real gain in revenues. Indiaâs commodity futures markets
are no exception to this rule, and these markets in India are both highly
successful, and yet fragile because so new. No new commodity
transaction tax should be implemented."
