Allowing for sign-dependence in discounting substantially improves the description of people’s time preferences. The … practice in modeling intertemporal choice where sign-dependence is largely ignored and only decreasing impatience is allowed …

explore the relationships in detail. Among other things, we show that (1) volatility dependence produces sign dependence, so … long as expected returns are nonzero, so that one should expect sign dependence, given the overwhelming evidence of … volatility dependence; (2) it is statistically possible to have sign dependence without conditional mean dependence; (3) sign …
