This essay corrects the results reported in Gerber and Green 2000 and replies to Imai (2005). When data-processing errors are repaired, the original substantive findings from the New Haven experiment remain unchanged. As previously reported, brief phone calls do not increase voter turnout. The “correction” that Imai (2005) offers, which purports to show that these phone calls produce large, sig...

In this paper, we consider a dual risk process which can be used to model the surplus of a business that invests money constantly and earns gains randomly in both time and amount. The occurrences of the gains and their amounts are assumed follow a semi-Markovian structure (e.g. Reinhard (1984)). We analyze a quantity resembling the Gerber-Shiu expected discounted penalty function (Gerber and Sh...

In this paper we consider a risk model with two classes of insurance risks in the presence of multiple thresholds. We assume that the two claim counting processes are, respectively, Poisson and Sparre Andersen with generalized Erlang(2) claim inter-arrival times. We derive an integro-differential system for the Gerber-Shiu functions for surplus-dependent premium rates and a piecewise integro-di...

In their landmark study of a field experiment, Gerber and Green (2000) found that get-out-the-vote calls reduce turnout by five percentage points. In this article, I introduce statistical methods that can uncover discrepancies between experimental design and actual implementation. The application of this methodology shows that Gerber and Green’s negative finding is caused by inadvertent deviati...

In this paper we consider a risk model with two classes of insurance risks in the presence of a multi-layer dividend startegy. We assume that the two claim counting processes are, respectively, Poisson and Sparre Andersen with generalized Erlang(2) claim inter-arrival times. We derive an integro-differential equation system for the Gerber-Shiu functions for surplus-dependent premium rates and a...

Diet quality is an important measure in understanding food security because of the synergistic nature of microand macronutrients (Gerber, 2001 [1]) and the association of healthy diet patterns with reduced risk for diet-related disease and illness (Kant, 1996 [2]). The Diet Quality Index ? International (DQI-I) is a composite, individual-level diet quality indicator. It was created in 2003 to e...

The aim of this work is to use a duality approach to study the pricing of derivatives depending on two stocks driven by a bidimensional Lévy process. The main idea is to apply Girsanov’s Theorem for Lévy processes, in order to reduce the posed problem to the pricing of a one Lévy driven stock in an auxiliary market, baptized as “dual market”. In this way, we extend the results obtained by Gerbe...
