It is increasingly understood across the information technology and services sector that engagement with the open source software model can serve as a means for firms to capture intellectual energy, learn about productive software processes, access relevant technical skills, identify and recruit...

The main objective of this paper is to propose a feasible, model free estimator of the predictive density of integrated volatility. In this sense, we extend recent papers by Andersen et a]. [Andersen, T.G., Bollerslev,T., Diebold, FX, Labys, P., 2003. Modelling and forecasting realized...

This paper applies a geo-additive generalized linear mixed model to describe the spatial variation in the prevalence of cough among children under 5 years of age using the 2000 Demographic and Health survey (DHS) data from Malawi. Of particular interest in the analysis were the small area effect...

We introduce the concept of inconsequential arbitrage and, in the context of a model allowing short-sales and half-lines in indifference surfaces, prove that inconsequential arbitrage is sufficient for existence of equilibrium. Moreover, with a slightly stronger condition of nonsatiation than...

This paper has two main purposes. Firstly, we develop various ways of defining efficiency in the case of multiple-output production. Our framework extends a previous model by allowing for nonseparability of inputs and outputs. We also specifically consider the case where some of the outputs are...

In this study multi-fidelity surrogate modelling for combining data sets of wind tunnel experiments and computations is examined, dealing with different types of errors. Co- kriging regression is constructed with the low-fidelity sample data of the computations and the high-fidelity data of the...

This paper describes the field implementation and validation of the Becker‐DeGroot‐Marschak (BDM) (1964) mechanism to measure willingness to pay in the context of a point‐of‐use water treatment product in Ghana. BDM has the potential to provide precise data through which to study both...

Organizational economics has advanced along two parallel tracks, one concerned with motivating agents with diverging objectives, the other - less developed - with coordinating agents with cognitive limits. This survey focuses on the second strand and on attempts to bring the two strands...

Creative destruction is an economic theory of innovation popularised by the Austrian economist Joseph Schumpeter (2006). In this paper, Schumpeter’s theories are used to explain how radical technological innovations in information-intensive industries are influencing the erosion of traditional...
