In addition, this positive shift mostly happens right after retirement immediately and is mainly driven by the fact that households without risky assets start to hold risky assets after retirement. Evidence in support of (a) shifts in risk tolerance and (b) spending additional time tracking the stock market is presented.
markets with higher housing price growth, banks with higher OTD participation extended mortgages to riskier borrowers, and thus, had larger incidence of defaults once house prices declined.

Both window dressing and screening efforts are shown to depend on the state of the economy: better states exhibit greater window dressing and less screening. The rating quality and default probability for given ratings also vary with economic conditions, and credit spreads adjust to such variations.
