Using micro-level data from the mortgage market, we examine yield spreads as a funnction of both credit risk and prepayment risk using a two-stage instrumental variable approach. Our results are consistent with findings in the finance literature that leverageinduced financial risk reflected in capital structure results in higher yield spreads on debt. In particular, borrowers with loan-to-value...

In order to explore the possible mechanisms by which ethologically relevant sounds can be extracted from complex auditory environments, this study examined the effects of weak noise on the rate-intensity functions (RIFs) of neurons responding to tone burst in the inferior colliculus (IC) of nine mice (Mus musculus Km). Under free field stimuli conditions, a total of 112 IC neurons were recorded...
