DSGE Models in a Data-Rich Environment

Abstract: Standard practice for the estimation of dynamic stochastic general equilibrium (DSGE) models maintains the assumption that economic variables are properly measured by a single indicator, and that all relevant information for the estimation is summarized by a small number of data series. However, recent empirical research on factor models has shown that information contained in large data sets is relevant for the evolution of important macroeconomic series. This suggests that conventional model estimates and inference based on estimated DSGE models might be distorted. In this paper, we propose an empirical framework for the estimation of DSGE models that exploits the relevant information from a data-rich environment. This framework provides an interpretation of all information contained in a large data set, and in particular of the latent factors, through the lenses of a DSGE model. The estimation involves MarkovChain Monte-Carlo (MCMC) methods. We apply this estimation approach to a state-of-the-art DSGE monetary model. We find evidence of imperfect measurement of the model’s theoretical concepts, in particular for inflation. We show that exploiting more information is important for accurate estimation of the model’s concepts and shocks, and that it implies different conclusions about key structural parameters and the sources of economic fluctuations.

A Tabu Search Algorithm for a Routing and Container Loading Problem

Abstract: This article considers a combination of capacitated vehicle routing and three-dimensional loading, with additional constraints frequently encountered in freight transportation. It proposes a tabu search algorithm that iteratively invokes an inner tabu search procedure for the solution of the loading subproblem. The algorithm is experimentally evaluated both on instances adapted from vehicle routing instances from the literature and on new real-world instances.

Further Understanding of Trust and Performance in Virtual Teams

Abstract: Trust has been deemed to be critical in ensuring the efficient operation of virtual teams and organizations. This study empirically verifies ability and integrity as being antecedents of trust formation in virtual teams. However, effective team performance was found to be independent of the formation of trust. Further analysis suggests that information symmetry and good communication distinguish high performance teams from low performance teams.

Challenges in Conducting Empirical Work Using Structuration Theory: Learning from IT Research

Abstract: Giddens’s structuration theory is increasingly used as an alternative approach to studying numerous organizational phenomena. However, the applicability of Giddens’s concepts is not without difficulties because of two main challenges. First, structuration theory is complex, involving concepts and general propositions that operate at a high level of abstraction. Second, structuration theory is not easily coupled to any specific research method or methodological approach, and it is difficult to apply empirically. Arguing that structuration theory is a valuable framework for a rich understanding of management, organization and related subjects of inquiry, this paper aims to improve the application of structuration theory in empirical work by drawing on the experience in information technology (IT) research. It identifies patterns of use of Giddens’s theory in publications in the domain of IT, and then describes how IT researchers have attempted to address its major empirical challenges. The paper presents a ...
