The Predictive Power of Anisotropic Spatial Correlation Modeling in Housing Prices

This paper develops a method to capture anisotropic spatial autocorrelation in the context of the simultaneous autoregressive model. Standard isotropic models assume that spatial correlation is a homogeneous function of distance. This assumption, however, is oversimplified if spatial dependence changes with direction. We thus propose a local anisotropic approach based on non-linear scale-space image processing. We illustrate the methodology by using data on single-family house transactions in Lucas County, Ohio. The empirical results suggest that the anisotropic modeling technique can reduce both in-sample and out-of-sample forecast errors. Moreover, it can easily be applied to other spatial econometric functional and kernel forms.     

Why Do REIT Prices Change? The Information Content of Barron's “The Ground Floor”

This article examines the information content in a series of market commentaries covering the publicly traded real estate market. The data are constructed from REIT-specific announcements published in a widely disseminated source of market commentary. The empirical methodology is designed to test whether the unexpected price change and unexpected volume are significant on the announcement day. The results demonstrate that the market commentaries provide information that impacts prices and that investors use this information in their trading. Additional analysis suggests that prices change more in the period following the REIT boom than during an earlier period. This result seems somewhat puzzling given recent studies that report an increase in REIT market liquidity.     

Work and Volunteering: Longitudinal Relationships between Work‐Related Experiences and Volunteering Behaviour

This study examines the effect of work‐related experiences on employees’ engagement in community volunteering, using data from a British longitudinal panel of employees. Using a novel analytical approach that separates variation in volunteering due to within‐person changes in work conditions from variation due to between‐person work differences, we more robustly test existing and new hypotheses about the effects of work on volunteering. New to this literature, we find that commuting and satisfaction with job experiences are significant predictors of community volunteering, both the likelihood to volunteer and volunteering frequency. In turn, volunteering determinants previously explored with cross‐sectional data, such as managerial and professional jobs, employment sector and hourly paid contracts, are no longer statistically significant in the within‐person models. We discuss a number of important theoretical and practical consequences of these findings.     

Sicherungssysteme für Finanzdienstleistungsunternehmen im europäischen Vergleich – Theorieperspektive

The contribution discusses the design of guarantee schemes for financial services firms, with a focus on insurance guarantee schemes. It lists reasons that contribute to the development of guarantee schemes, especially stemming from a market failure risk. It further describes the pros and cons of ex-ante and of ex-post premium payments, and sets out arguments for and against risk based premiums of insurance guarantee schemes. The contribution also investigates whether the existence of insurance guarantee schemes might lead to a more risky insurance firm policy. Finally it examines in how far consumer protection based on insurance guarantee schemes prevents consumer protection based on market discipline that should be achieved by the third pillar of Solvency II.     

Information Producers and Valuation: Evidence from Real Estate Markets

This paper examines valuation and its relation to information production by licensed appraisers across real estate markets. The testable implications are discussed for either a peer monitoring or a crowding out effect in the data. The empirical model is estimated with data for all 50 US states and DC covering the sample period from 1999 to 2008. While analysis is primarily cross-sectional and not causal, the evidence is consistent with theory stating that the minimum quality associated with residential licensure standards may be too low. In contrast, the evidence suggests certified residential standards afford information producers the opportunity to signal or information consumers the ability to screen based on quality.     

Actor network pictures and networking activities in business networks: An experimental study

In recent years, there has been increasing interest among business-to-business marketing scholars in the processes of managerial cognition. In particular, actors' network pictures, defined as the cognitive representations of managers' business surroundings have attracted much attention. However, there has so far been no empirical research on the impact that network pictures have on managerial behavior. The purpose of this paper is therefore to understand if and how specific pertinent network picture characteristics — namely power, dynamics, broadness, and indirectness — are associated with different behavioral choices, i.e. networking strategies. Based on an experiment with 445 Executive MBA students, all international managers across different industries, we find that managers' choices when managing business relationships, their strategic actions, are affected by the way they perceive their surrounding business network. However, amongst the different theoretical models of networking activities tested, only the power dimension showed significant associations with all four network picture characteristics. This study represents the first to empirically study the connection between cognition and behavior in business-to-business markets, as well as one of the few to apply an experimental design to study a business-to-business marketing related phenomenon. Also, it paves the way for future understanding of the association between network picture characteristics and networking strategies in interaction between actors.
