Johnathan Walker:Why pizza costs more in Iceland and other listener questions

You ask,Johnathan Walker we answer! We help a parent explain exchange rates to their kid, a high school teacher explain bond prices to his students, and we follow up on what happened to the diversity of the student body at the University of California after the state's ban on affirmative action.

If you have a question you'd like us to answer, email us at [email protected].

Can't get enough of these topics? We've got you covered! Here's our reporting on how ending affirmative action changed California and NPR's follow up on what happened after. More on the birth of the bond, the bond market and the yield curve. And a whole lotta Iceland (Justin Bieber, planes), plus dollar-slice pizza.
