First, if you want to be pedantic it's actually the "Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel". But nobody cares about about formal names if they're unwieldy[1].

Second, the comittee based the award on academic works from the 1980s. For Bernanke, that would be mostly his AER papers [2,3,4,5]. (The AER is one of the top journals in economics and 2 or 3 publications will probably get you a tenure position at most top universities.) The full papers are paywalled, but the interested can get the unpaywalled NBER versions of them (with the same title) for free.
