Show/Hide Abstract Modeling House Price Dynamics with Heterogeneous Speculators (2013)
Roberto Dieci Frank Westerhoff
This paper investigates the impact of speculative behavior on house price dynamics. Speculative demand for housing is modeled using a heterogeneous agent approach, whereas ‘real’ demand and housing supply are represented in a standard way. Together, real and speculative forces determine excess demand in each period and house price adjustments. Three alternative models are proposed, capturing in different ways the interplay between fundamental trading rules and extrapolative trading rules, resulting in a 2D, a 3D, and a 4D nonlinear discretetime dynamical system, respectively. While the destabilizing effect of speculative behavior on the model’s steady state is proven in general, the three specific cases illustrate a variety of situations that can bring about endogenous dynamics, with lasting and significant price swings around the ‘fundamental’ price, as we have seen in many real markets.
Show/Hide Abstract Effects of Inflation Expectations on Macroeconomic Dynamics: Extrapolative Versus Regressive Expectations (2012)
Marji Lines Frank Westerhoff
In this paper, we integrate heterogeneous inflation expectations into a simple monetary model. Guided by empirical evidence, we assume that boundedly rational agents, selecting between extrapolative and regressive forecasting rules to predict the future inflation rate, prefer rules that have produced low prediction errors in the past. We show that integrating this behavioral expectation formation process into the monetary model leads to the possibility of endogenous macroeconomic dynamics. For instance, our model replicates certain empirical regularities such as irregular growth cycles or inflation persistence. Moreover, we observe multi-stability via a Chenciner bifurcation.
Show/Hide Abstract BPEL Conformance in Open Source Engines (2012)
Simon Harrer Jörg Lenhard Guido Wirtz
More than five years have passed since the final release of the long-desired OASIS standard of a process language for Web Services orchestration, the Web Services Business Process Execution Language (BPEL). The aim of this standard was to establish a universally accepted Web Services orchestration language that forms a core part of service-oriented architectures and, because of standardization, avoids vendor lock-in. By now, several fully conformant engines should have arrived in the market. It is our aim to shed light on this situation and to provide a comprehensive picture of the current state of BPEL upport. We present an evaluation of the standard conformance of five open source BPEL engines. To obtain these results we have developed betsy, a tool that allows for a fully-automatic standard conformance testing of BPEL engines. The results demonstrate that full standard conformance in contemporary engines is still far from given.
Show/Hide Abstract How management actions affect social exchanges in outsourcing relationships (2013)
Anna Wiesinger Daniel Beimborn
This paper explores the effect of management actions on social exchanges in outsourcing relationships. Social exchanges between individuals constitute relationship quality between client and vendor, which is an important factor of outsourcing success. Based on the interaction approach, we develop a framework for management actions entailing three dimensions: the exchange targeted, the organization targeted and the effect on social exchanges. We apply the framework to studying a comprehensive case of an outsourcing relationship full of conflict. This proof-of-concept shows that it is vital to consider side effects of management actions on social exchanges as they indirectly influence outsourcing success.
Show/Hide Abstract Online Social Networks as a Source and Symbol of Stress: An Empirical Analysis (2012)
Christian Maier Sven Laumer Andreas Eckhardt Tim Weitzel
This research examines the sources and consequences of stress when using online social networks (OSN). In a first step, the five OSN-induced stressors invasion, pattern, complexity, uncertainty, and disclosure are identified. In a second step, the Model of Continuous OSN Usage is developed in order to examine the influence of these five stressors. Therefore, the model is based on the Model of Adoption of Technology in Households and the Post-Acceptance Model. Results of an empirical analysis with 154 OSNs users reveal that 57 per cent of satisfaction and 64 per cent of continuous usage intention can be explained within the Model of Continuous OSN Usage. Notably, the five stressors have a higher strength of effect on satisfactions than the three attitudinal beliefs hedonic, utilitarian, and social outcomes altogether. In summary, the results offer a theoretical foundation for recent practical observations that OSNs are a source and symbol of stress.
Show/Hide Abstract The Influence of Pressure to Perform and Experience on Changing Perceptions and User Performance: A Multi-Method Experimental Analysis (2012)
Andreas Eckhardt Christian Maier Ricardo Buettner
To address shortcomings of predominately subjective measures in empirical IS research on IT usage and human-computer interaction, this paper uses a multi-method experimental analysis extending empirical surveying with objective measures from eye-tracking and electrodermal activity (EDA). In a three stage process, objective user performance is observed in terms of task fulfillment and user performing of participants in four focus groups, classified by user system experience and the treatment pressure to perform. Initial results of this research-in-progress reveal that users with prior system experience perform considerably better and faster than users without system experience. This also accounts for users under pressure to perform compared to users without pressure to perform. However, the results of the EDA show that users under pressure to perform also have a higher objective strain level. Furthermore, a first regression analysis outlines that objective performance might help to understand user's system satisfaction to a greater extent.
