Daily Inspiration Quote by Joseph Stiglitz

Stiglitz is taking a scalpel to a comforting civic myth: that markets run on transparent prices and rational actors who just "respond to incentives". In his world, incentives are inseparable from the costly, uneven, and strategic production of knowledge. The line is almost bureaucratic in tone, but it smuggles in a radical claim: information is not a free side note to economic life; it is one of the main things economic life is about.

The specific intent is to reposition "beliefs" as an economic variable. People and firms aren’t merely choosing between products or investments; they’re choosing how much certainty they can afford. That shifts attention from outcomes to the machinery that manufactures them: analysts, credit ratings, market research, lobbying, PR, due diligence. These aren’t frictions around an efficient core. They are the core, and they cost real money.

The subtext is power. If information is expensive, then advantage accrues to whoever can pay to acquire it, shape it, or hide it. "Actions of others" affecting beliefs points to feedback loops where behavior becomes signal: a big investor buys, others infer confidence; a firm overinvests in branding, consumers infer quality; a bank tightens credit, markets infer danger. Beliefs cascade, sometimes untethered from fundamentals, because everyone is watching everyone else.

Contextually, this is Stiglitz’s signature terrain: information asymmetry as a reason markets misfire, not merely misprice. It’s also a quiet critique of policies that assume disclosure alone fixes everything. If belief formation is an arms race, then "more information" can just mean more weaponized persuasion.
