Natural Capitalism Problems such as pollution and social injustice may then be seen as failures to properly account for capital, rather than as inherent failures of capitalism itself. The fundamental assumptions of are as follows: In a 2009 interview, Paul Hawken described his motivation behind the title ""Natural Capi...

Gresham's law In economics, is a monetary principle stating that "bad money drives out good". For example, if there are two forms of commodity money in circulation, which are accepted by law as having similar face value, the more valuable commodity will gradually disappear from circulation. The law was named in 1860 by...

Gresham's law Coins of this type are of a known purity and are in a convenient form to handle. People prefer trading in coins rather than in anonymous hunks of precious metal, so they attribute more value to the coins of equal weight. The price spread between face value and commodity value is called seigniorage. As som...
