Local differential privacy has recently surfaced as a strong measure of privacy in contexts where personal information remains private even from data analysts. Working in a setting where both the data providers and data analysts want to maximize the utility of statistical analyses performed on the released data, we study the fundamental trade-off between local differential privacy and utility. ...

The problem of dynamic portfolio choice with transaction costs is often addressed by constructing a Markov Chain approximationof the continuous timeprice processes. Using this approximation,wepresent an efficient numerical method to determine optimal portfolio strategies under timeand state-dependent drift and proportional transaction costs. This scenario arises when investors have behavioral b...

In the area of dynamic revenue management, optimal pricing policies are typically computed on the basis of an underlying demand rate model. From the perspective of applications, this approach implicitly assumes that the model is an accurate representation of the real world demand process and that the parameters characterizing this model can be accurately calibrated using data. In many situation...

W consider choice over uncertain, monetary payoffs and study a general class of preferences. These preferences favor diversification, except perhaps on a subset of sufficiently disliked acts over which concentration is instead preferred. This structure encompasses a number of known models (e.g., expected utility and several variants under a concave utility function). We show that such preferenc...

We introduce a unified framework for the study of the utility and the energy efficiency of solutions to a large class of weighted max-min utility maximization problems in interferencecoupled wireless networks. In more detail, given a network utility maximization problem parameterized by a maximum power budget p̄ available to network elements, we define two functions that map the power budget p̄ t...

INTRODUCTION Administration of human C1 esterase inhibitor (Berinert(®) P) from target import is the most widespread treatment strategy for patients with hereditary angioedema (HAE). However, a therapeutic health program including Ruconest(®) (conestat alfa) could shorten a patient's expectancy for a life-saving treatment. AIM To evaluate the cost-utility of Ruconest(®) (conestat alfa) financ...

The main objective of this paper is to address, in an a continuous-time framework, the issue of using storable commodity futures as vehicles for hedging purposes when, in particular, the convenience yield as well as the market prices of risk evolve randomly over time. Following the martingale route and by operating a suitable constant relative risk aversion utility function (CRRA) specific chan...

We present time/utility function (TUF) algorithms that provide probabilistic assurance on timeliness behavior. A TUF, which is a generalization of the classical deadline constraint, specifies the utility of completing an application activity as a function of that activity’s completion time. The algorithms consider a stochastic model where activity execution times and arrivals are probabilistica...

in children. although its burden is considerably preventable by vaccine, routine vaccination against hib has not been defined in the national immunization program of iran. this study was performed to assess the cost-benefit and cost‑utility of running an hib vaccination program in iran. methods: based on a previous systematic review and meta‑analysis for vaccine efficacy, we estimated the avert...
