The classical Fisher equation asserts that in a nonstochastic economy, the inflation rate must equal the difference between the nominal and real interest rates. We extend this equation to a representative agent economy with real uncertainty in which the central bank sets the nominal rate of...

We use administrative and survey-based micro data to study the relationship between cognitive abilities (IQ), the formation of economic expectations, and the choices of a representative male population. Men above the median IQ (high-IQ men) display 50% lower forecast errors for inflation than...

Intertemporal substitution is at the heart of modern macroeconomics and finance as well as economic policymaking, but a large fraction of a representative population of men - those below the top of the distribution by cognitive abilities (IQ) - do not change their consumption propensities with...

Communication targeting households and firms has become a stand-alone policy tool of many central banks. But which forms of communication, if any, can reach ordinary people and manage their economic expectations effectively? In a large-scale randomized control trial, we show that communication...

Many consumers below the top of the distribution of a representative population by cognitive abilities barely react to monetary and fiscal policies that aim to stimulate consumption and borrowing, even when they are financially unconstrained and despite substantial debt capacity. Differences in...

Communication targeting households and firms has become a stand-alone policy tool of many central banks. But which forms of communication, if any, can reach ordinary people and manage their economic expectations effectively? In a large-scale randomized control trial, we show that communication...

Unique administrative data on a representative population's cognitive abilities, spending, and financials reveal that consumers at or below median cognitive abilities barely react when their incentives to spend or borrow change, even if they earn high incomes and are financially unconstrained...
