Eye-Tracking im Einzelhandel - Ein Leitfaden für die Blickaufzeichnung

Die Frage, welche Artikel wo im Regal platziert werden sollten, l?sst sich nicht allein mit Abverkaufsdaten beantworten. Vielmehr gilt es zu untersuchen, wie sich Kunden vor dem Regal verhalten und wie sie die Warenplatzierungen wahrnehmen. Ein Instrument dafür ist das Eye-Tracking. Die Blickaufzeichnung erlaubt es, das Such- und Orientierungsverhalten am Regal mit den Augen der Kunden zu sehen. Um aussagekr?ftige Ergebnisse aus einer Eye-Tracking-Studie zu erhalten, sind bestimmte Anforderungen zu erfüllen. Ein Leitfaden.     

How Likely are Employers to Rehire Older Workers After Mandatory Retirement? A Vignette Study Among Managers

With a vignette experiment among Dutch managers we examine employers’ considerations in the decision to rehire employees after mandatory retirement. We specifically focus on the effects of the employee’s downward wage flexibility (i.e., the willingness to accept a lower wage) and contract flexibility (i.e., preference for a contract which allows flexible hours or employment). The results show that employers are strongly affected by employees who offer to work for a significantly lower wage, but not by the employees’ preference for a particular labor contract. Employers are overall quite disinclined to rehire employees after mandatory retirement, although large differences exist between employees. Part of these differences can be explained by employers having higher retirement age norms (i.e., the maximum age at which employers consider employees suited for work in their organization).     

Identifying relevant and irrelevant variables in sparse factor models

This paper considers factor estimation from heterogeneous data, where some of the variables—the relevant ones—are informative for estimating the factors, and others—the irrelevant ones—are not. We estimate the factor model within a Bayesian framework, specifying a sparse prior distribution for the factor loadings. Based on identified posterior factor loading estimates, we provide alternative methods to identify relevant and irrelevant variables. Simulations show that both types of variables are identified quite accurately. Empirical estimates for a large multi‐country GDP dataset and a disaggregated inflation dataset for the USA show that a considerable share of variables is irrelevant for factor estimation.     

The Incidence of EU Per‐Hectare Payments on Farmland Rental Rates: A Spatial Econometric Analysis of German Farm‐Level Data

This article analyses determinants for 2001 farmland rental prices from 3,819 farms in Germany. Based on specification tests we estimate a general spatial model to account for both spatial relationships among rental prices of neighbouring farmers and spatially autocorrelated error terms. A €1 per hectare higher rental price in a farmer’s neighbourhood coincides with a €0.72 higher rental price paid by the farmer. The marginal incidence of EU per‐hectare payments paid for eligible arable crop land on rental rates amounts to €0.38 for each additional €1 of premium payments. Regional livestock density, which is indirectly influenced by different policies, is also a major determinant of rental prices. Results are confirmed by sensitivity analyses. Consequently, German farmland rental rates are heavily influenced by agricultural policy instruments and therefore, these policies exhibit substantial distributional effects.     

The influence of causation and effectuation logics on targeted policies: the cases of Singapore and Israel

We examine the causation and effectuation logics for implementing targeted biotechnology policies using two case studies: Singapore (causation) and Israel (effectuation). After more than a decade of implementing targeted biotechnology policies, both Singapore and Israel have failed to create fully fledged biotech clusters. Singapore has been unsuccessful in creating vibrant entrepreneurial activity that will support its transformation into a knowledge economy. Israel has failed to turn its 1000 small, dedicated biotechnology firms into a substantial engine of growth and employment. The paper questions how these two policy approaches influenced the targeting of the biotechnology sectors and identifies the limits of these approaches in supporting targeting. We conclude that a combination of the two logics is needed, especially when targeting complex sectors with a yet unknown development path.     

Franchisee Associations: Strategic Focus or Response to Franchisor Opportunism

This article examines some of the antecedents, processes, and effects of independent franchisee associations (IndFAs) and the reactions of franchisors to their organization. Specifically, we draw on various literatures to pose propositions relating to the following research questions: (a) Are there fundamental differences between associations whose focus is based on disagreements relating to strategic actions of the franchisor and those whose focus is perceived opportunistic behavior on the part of the franchisor? (b) Does the way these IndFAs are treated by the franchisor—after inception—affect members' identification with the group and/or franchisor? (c) Does the existence of a franchisee advisory council influence the willingness of a franchisor to legitimize an IndFA? (d) How does the size of the IndFA influence identification? We then present a conceptual model and use two illustrative examples from the business literature to explore our propositions.     

Trip chaining behavior in multi-destination shopping trips: A field experiment and laboratory replication

Models of consumer store patronage generally employ the economic theory-based assumption that, all else being equal, consumers seek to minimize travel distance. Moreover, consistent with reference-dependent theory, findings from recent experimental research conducted in a controlled lab setting suggest that holding travel distance constant, the configuration of stops along multi-stop routes may also impact store-patronage decisions. However, given the use of simplified map configurations of multi-stop routes, along with the stimulus-based nature of the laboratory exercise, the external validity of these findings are open to question. Thus, the purpose of the three experiments in the present paper is to replicate and test the external validity of the reference-dependent predictions supported in previous research. In experiment one, consumer travel preferences are examined in a memory-based field experiment with results replicating those of earlier research. In experiment two, results are again replicated, but this time in a lab setting using realistic maps. Finally, experiment three provides a test of boundary conditions for the theory-consistent results of experiments one and two.
