A OP's second expression corresponds to $$\Delta p = P(Y=1|D=1,X=\bar{X}) - P(Y=1|D=0,X=\bar{X}),$$ which is $$ \Delta p = \Lambda(\beta_0 + \beta_1 + \beta_2 \bar{X}) - \Lambda(\beta_0 + \beta_2 \bar{X}), $$ where $\Lambda(z) = e^z/(1+e^z)$. Rationale for dividing by p OP's first expression corresponds to $(\Delta p)/p$, where $p$ is the proportion of 1'...

The word "noise" implies that there is error in the measurement of household debt, but there is no good reason to believe this is so. In fact, I argue that a finer time period would give you more detail, and a more accurate measurement of the correlation between two variables. You don't want to find a moving average because that throws away valuable ...

There are many methods to forecast exchange rates- look at the series of influential papers by Meese and Rogoff for a primer (https://scholar.harvard.edu/files/rogoff/files/51_jie1983.pdf). To answer your particular question- what you describe seems to be driven by multicollinearity. For instance, returns on stocks will be correlated with the inflation ...
