This paper constructs a class of multivariate Gaussian marked Poisson processes to model asset returns. The model proposed accommodates the cross section properties of trades, allows for returns to be correlated conditional on trading activity, and preserves the economic intuition of normality of returns conditional on trading activity. We prove that the new class of processes are in law subord...

Urban migration in developing countries is expected to increase the number of slum inhabitants from 940 million in 2003 to over two billion by 2030. As socio-economic status at birth is a strong predictor of future socio-economic status, slum children seem destined to a life of poverty. However, emerging examples of empowerment appear to demonstrate possibilities of information technology to be...

A well-functioning credit market is a central driver of economic growth. At the same time, academics, policymakers, as well as the general public, have long been concerned that in some situations borrowing can actually end up hurting consumers. This concern has resurfaced with particular poignancy in the recent financial crisis, as subprime mortgages, credit cards, payday loans, and other credi...

Mobile technologies are reshaping the global economic landscape, enhancing speed and comfort of communication and information exchange. Existing studies on the economic impact of mobile technologies taking a socio-technical system perspective are scarce. Our study shortly describes an integrative approach for such systems, which is in detail described in Högler et al. (2015), and specifically c...

This paper constructs a macro-finance model for commodity futures, and documents a new empirical fact that real economic activity forecasts oil futures returns and prices. The model generalizes previous futures pricing models and indicates a time-varying oil risk premium that covaries strongly with the business cycle. Model estimates reveal rich dynamics between economic activity and oil future...

Management of applications in the new world of pervasive computing requires new mechanisms to be developed for admission control, QoS negotiation, allocation and scheduling. To solve such resourceallocation and QoS provisioning problems within pervasive and ubiquitous computational environments, distribution and decomposition of the computation are important. In this paper we present a QoS-base...

Introduction: The existence of standard tools is one of the basic needs of scientists of healthy behavior for predicting health-related behaviors. The aim of the present study was to design a psychometrically sound instrument to measure the protection motivation theory constructs regarding self-medication for elderly Iranians. Methods: The study was conducted in spring 2016. The sample con...
