\"Market<\/a><\/p>\n

The important concept of market efficiency was introduced. The theorem that
\nwas proved was a \u201cno trade\u201d theorem. If investors had common prior beliefs \u00a0then even
\nif they had different information, they would all refrain from trading purely speculative
\nclaims, and each asset would be priced so that its expected return was equal to the riskless
\nreturn.
\nThe basic intuition for this result was that in a purely speculative market the risk of the
\nassets was not inherent to the economy and could be avoided by every investor. Investors
\nwould trade therefore only when they believed they were receiving a favorable \u201cbet.\u201d Each
\ninvestor realized that all of the other investors also thought this way, so whenever some other
\ninvestor was willing to take the opposite side of a transaction, this had to be understood as
\nbeing based on some information that the first investor did not know. Realizing this, both
\ninvestors would revise their beliefs until they came into concordance.
\nIf markets are not purely speculative, then this result no longer holds. Investors may
\nbe willing to take unfavorable \u201cbets\u201d if they offset some of the risk of their other holdings.
\nThat is, an investor may trade to get a favorable return or <\/i>to reduce risk. It is, however,
\npossible to separate these two motives for trade and derive a \u201cno trade\u201d theorem in other
\nthan purely speculative markets. Like the previous theorem in this chapter, this result also
\ndepends on the market being effectively complete.
\nThe basic structure of the economy is as follows. There is an initial round of trading in
\nwhich a Pareto optimal allocation of period-0 consumption and period-i wealth is achieved.
\nThat is, the initial round of trading takes place in an effectively complete market. After
\nthis equilibrium is reached, investors consume. Then they receive private information, and
\nthe market reopens for trading. In this second round, investors may also learn from the
\nequilibrium price or other public information. Each investor knows that this is the structure
\nof the economy and knows before the first round of trading all the possible states (i.e., the
\nprivate information does not cause any investor to believe that the structure of the economy
\nis changed or that any new states are possible).<\/p>\n
