Institutions don't matter
Distribution of wealth doesn't matter ? Information asymmetry = in economics it is the study of decisions in transactions where one party has better or more information than the other neo-classical economics assumes perfect information Information asymmetry creates imbalance of power market failure people buying insurance know more than the insurance company
“sort” customers by risk category --> "screening"
offering a range of insurance products and letting the customers select.

Credit markets --> lenders charge higher interest rates to higher-risk borrowers

Stiglitz’s work with Carl Shapiro on “efficiency wages” --> explains unemployment
Stiglitz critical of free markets because of information asymmetries
a free and competitive market is highly beneficial to society at large, but it needs government regulation and oversight to remain functional
Stiglitz called for government intervention to correct market failures
He showed how it is possible for government to improve on markets --> Firestone tyres company Some of his famous and most recent books include:

"Economics for an Imperfect World" --> Essays in Honor of Joseph E. Stiglitz
One of the founders of modern development economics
--> asymmetric information and economic incentives have explanatory value for analysis of developing economies

It is not uncontrollable technological and social change that has produced a two-tier society, but the exercise of political power by moneyed interests over legislative and regulatory processes. “While there may be underlying economic forces at play,” he writes, “politics have shaped the market, and shaped it in ways that advantage the top at the expense of the rest.” Conservative advocates of pure free markets fail to acknowledge how concentrated economic power converts into political power.
