Polar Coordinates for the 3/2 Stochastic Volatility Model

open access: yesMathematical Finance, EarlyView.
ABSTRACT The 3/2 stochastic volatility model is a continuous positive process s with a correlated infinitesimal variance process ν$\nu $. The exact definition is provided in the Introduction immediately below. By inspecting the geometry associated with this model, we discover an explicit smooth map ψ$ \psi $ from (R+)2$({\mathbb{R}}^+)^2 $ to the ...

Coordination of distributed adaptive signal control and advisory speed optimization based on shockwave theory

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract This paper presents a distributed adaptive signal control and advisory speed coordination method based on shockwave theory, which accommodates diverse traffic conditions. In order to assess signal control efficiency under various scenarios, an innovative evaluation index termed synthetic delay is introduced based on the analysis of traffic ...

Does Less Education Harm Health? Evidence From a Natural Experiment in a Developing Country

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We investigate the health outcome effects of a reduction in years of schooling in Egypt in 1988, a policy change that moves in the opposite direction in relation to the extant literature. We exploit this policy change as a natural experiment and employ a fuzzy regression discontinuity design to investigate a range of objectively measured ...
