We point out that for two sets of measurements, it can happen that the average of one set is larger than the average of the other set on one scale, but becomes smaller after a non-linear monotone transformation of the individual measurements. We show that the inclusion of error bars is no safeguard against this phenomenon. We give a theorem, however, that limits the amount of “reversal” that ca...

There are many reasons to take a critical look at the practice's banking relationship(s)--technology advancements, security measures, improvements in available services, recent banking enhancements designed specifically for medical practices, the impact of the financial crisis on bank ratings and stability, changing practice needs, opportunities for operational automation at the practice--and i...

In this paper, we will explain how to perfectly hedge under Heston’s stochastic volatility 17 model with jump-to-default, which is in itself a generalization of the Merton jump-todefault model and a special case of the Heston model with jumps. The hedging instru19 ments we use to build the hedge will be as usual the stock and the bond, but also the Variance Swap (VS) and a Credit Default Swap (...

Proof. Since deterministic mechanisms are just special cases of random mechanisms, Theorem 1 applies: A deterministic mechanism f is strategyproof if and only if it is swap monotonic, upper invariant, and lower invariant. Thus, strategyproofness implies swap monotonicity (i.e., sufficiency in Proposition 5). For necessity, observe that swap monotonicity implies upper and lower invariance for de...
