By advancing a cross-sectional projection method developed by prior research and using firm-specific information in financial statements and business plans, we derive benchmarks for management revenue forecasts. With these benchmarks, we estimate forecast errors as an a priori measure of biased expectations. Using this measure for our proprietary dataset on venture-backed start-ups in Germany, we find evidence of substantial upward forecast biases. We uncover that firms with large forecast errors fail significantly more often than do less biased entrepreneurs in years following the investment. Overall, our results highlight the implications of excessive optimism and overconfidence in entrepreneurial environments and emphasize the relevance of accounting information and business plans for venture capital investment decisions.}}, author = {{Sievers, Sönke and Mokwa, Christopher Frederik}}, keywords = {{Management forecast biases, cross-sectional projection models, venture-backed start-ups, failure prediction, overoptimism, overconfidence}}, pages = {{31}}, title = {{{The Relevance of Biases in Management Forecasts for Failure Prediction in Venture Capital Investments}}}, doi = {{10.2139/ssrn.2100501}}, year = {{2012}}, } @techreport{2249, abstract = {{The phenomenon that groups or people work together when they face an opponent, although they have little in common otherwise, has been termed the "common enemy effect".

To address the issue of myopic management, our study shows how the complexity of the service profit chain (SPC) can cause managers to make suboptimal decisions. Hence, our paper departs from past research by recognizing that understanding the temporal interplay between operational investments, employee satisfaction, customer satisfaction, and operating profit is essential to achieving sustained success. In particular, we intend to improve understanding of the functioning of the SPC with respect to time lags and feedback loops. Results of our large-scale longitudinal study set in a multi-outlet retail chain reveal time-lag effects between operational investments and employee satisfaction, as well as between customer satisfaction and performance. These findings, along with evidence of a negative interaction effect of employee satisfaction on the relationship between current performance and future investments, show the substantial risk of mismanaging the SPC. We identify specific situations in which the dynamic approach leads to superior marketing investment decisions, when compared to the conventional static view of the SCP. These insights provide valuable managerial guidance for effectively managing the SPC over time.}}, author = {{Evanschitzky, Heiner and Wangenheim, Florian v and Wünderlich, Nancy}}, journal = {{Journal of Retailing}}, keywords = {{Employee satisfaction, Customer satisfaction, Performance, Service profit chain, Feedback loops, Time lags, Myopic marketing management}}, number = {{3}}, pages = {{356--366}}, publisher = {{Elsevier}}, title = {{{Perils of Managing the Service Profit Chain: The Role of Time Lags and Feedback Loops.}}}, volume = {{88}}, year = {{2012}}, } @article{5717, abstract = {{Although professional service providers increasingly deliver their services globally, little is known about cross-cultural differences in customers’ motivation to participate in service production.

In our set-up, countries are symmetric, but coalitions can be of arbitrary size. We analyze stability by means of a repeated game setting employing simple trigger strategies and we allow a sub-coalition to deviate from the coalitional equilibrium. For a given form of punishment we are able to rank the stability of different coalition structures as long as the size of the largest coalition does not change. Our main results are: (1) singleton regions have the largest incentives to deviate, (2) the stability of cooperation depends on the degree of cooperative behavior ex-ante.}}, author = {{Brangewitz, Sonja and Brockhoff, Sarah}}, publisher = {{Universität Paderborn}}, title = {{{Stability of Coalitional Equilibria within Repeated Tax Competition}}}, year = {{2012}}, }
