Monetizing the growth of mobile platforms is increasingly important as more and more users adopt mobile platforms such as the Google’s Android OS and the Apple’s iOS. In this study, we use a differential game theoretical model to study the problem of joint advertising investment and in‐app advertising adoption decisions by platform owners and app developers on a mobile platform. A key finding is that a platform owner may delay or even not offer an in‐app advertising program if the revenue from...]]>2019-05-20T21:35:38ZThe Value of a Statistical Life for Risk‐Averse and...
http://www.statisticsviews.com/details/journalArticle/11155732/The-Value-of-a-Statistical-Life-for-RiskAverse-and___.html
Abstract This article estimates the value of a statistical life (VSL) for Chile under the hedonic wage method while accounting for individual risk preferences. Two alternative measures of risk aversion are used. First, risk aversion is directly measured using survey measures of preferences over hypothetical gambles, and second, over observed individual behaviors that may proxy for risk preferences, such as smoking status, are used. I reconcile the results with a theoretical model of economic...]]>2019-05-20T15:19:36ZShelf Space Selection to Control Product Expiration
http://www.statisticsviews.com/details/journalArticle/11155985/Shelf-Space-Selection-to-Control-Product-Expiration.html
Product expiration is an important problem in the consumer‐packaged‐goods industry eroding profits and generating substantial waste. We propose that shelf space selection can be an operational lever to control expiration of perishable inventory. To this end, we first explain the conditions under which shelf space impacts expiration then develop a method to determine the appropriate level of shelf space which incorporates this impact. We formulate a shelf space selection problem for a single...]]>2019-05-20T05:39:03ZExpected market returns: SVIX, realized volatility, and the...

Summary This note provides a replication of Martin's (Quarterly Journal of Economics, 2017, 132(1), 367–433) finding that the implied volatility measure SVIX predicts US stock market returns up to 12‐month horizons. I find that this result holds for both S&P 500 and CRSP market returns, regardless of whether returns include or exclude dividends. The predictability largely disappears after the SVIX index is replaced by an exponentially weighted moving average measure of realized volatility,...]]>2019-05-20T03:31:00ZMathematical analysis of the motion of a rigid body in a...
http://www.statisticsviews.com/details/journalArticle/11155671/Mathematical-analysis-of-the-motion-of-a-rigid-body-in-a___.html
Abstract We study an initial and boundary value problem modelling the motion of a rigid body in a heat conducting gas. The solid is supposed to be a perfect thermal insulator. The gas is described by the compressible Navier–Stokes–Fourier equations, whereas the motion of the solid is governed by Newton's laws. The main results assert the existence of strong solutions, in an ‐ setting, both locally in time and globally in time for small data. The proof is essentially using the maximal...]]>2019-05-20T02:34:36ZSome new results on the preservation of the NBUE and NWUE...
http://www.statisticsviews.com/details/journalArticle/11155565/Some-new-results-on-the-preservation-of-the-NBUE-and-NWUE___.html
Abstract We consider the classical problem of whether certain classes of lifetime distributions are preserved under the formation of coherent systems. Under the assumption of independent and identically distributed (i.i.d.) component lifetimes, we consider the NBUE (new better than used in expectation) and NWUE (new worse than used in expectation) classes. First, a necessary condition for a coherent system to preserve the NBUE class is given. Sufficient conditions are then obtained for systems...]]>2019-05-18T00:00:00ZRethinking Resilience Analytics
http://www.statisticsviews.com/details/journalArticle/11155332/Rethinking-Resilience-Analytics.html
Abstract The concept of “resilience analytics” has recently been proposed as a means to leverage the promise of big data to improve the resilience of interdependent critical infrastructure systems and the communities supported by them. Given recent advances in machine learning and other data‐driven analytic techniques, as well as the prevalence of high‐profile natural and man‐made disasters, the temptation to pursue resilience analytics without question is almost overwhelming. Indeed, we find...]]>2019-05-17T13:14:22ZSpectral statistics of random Schrödinger operator with...

Abstract In this work we investigate the spectral statistics of random Schrödinger operators acting on where are i.i.d random variables distributed uniformly on [0,1].]]>2019-05-17T08:05:57ZOn the radius of spatial analyticity for the modified...

Abstract First, by using linear and trilinear estimates in Bourgain type analytic and Gevrey spaces, the local well‐posedness of the Cauchy problem for the modified Kawahara equation on the line is established for analytic initial data that can be extended as holomorphic functions in a strip around the x‐axis. Next we use this local result and a Gevrey approximate conservation law to prove that global solutions exist. Furthermore, we obtain explicit lower bounds for the radius of spatial...]]>2019-05-14T07:48:26ZCrossed product of C*‐algebras by hypergroups

Abstract The crossed product of ‐algebras by groups, groupoids and semigroups are well studied. In this paper we introduce and study the crossed product of ‐algebras by (locally compact) hypergroups. We calculate the crossed products by finite hypergroups of orders 2 and 3.]]>2019-05-14T07:42:22Z
