Organisational Behaviour and Corporate Success

This research group analyzes how non-monetary workplace characteristics (such as voice at the workplace or the perceived meaningfulness of the task) and managerial decision-making (e.g. as regards layoffs) influences the work motivation of employees. From a methodological persepective, the group focuses on conducting (field) experiments. First, such experiments allow us to obtain clean performance measures. Second, and more important, holding all things equal for every participating individual except for the treatment of interest, any change in workers’ performance can be put down to the experimenter’s intervention.

Paid Vacation Use: The Role of Works Councils

Laszlo Goerke Sabrina Jeworrek

in: Economic and Industrial Democracy, forthcoming

Abstract

The article investigates the relationship between codetermination at the plant level and paid vacation in Germany. From a legal perspective, works councils have no impact on vacation entitlements, but they can affect their use. Employing data from the German Socio-Economic Panel (SOEP), the study finds that male employees who work in an establishment, in which a works council exists, take almost two additional days of paid vacation annually, relative to employees in an establishment without such institution. The effect for females is much smaller, if discernible at all. The data suggest that this gender gap might be due to the fact that women exploit vacation entitlements more comprehensively than men already in the absence of a works council.

Wage Delegation in the Field

Sabrina Jeworrek Vanessa Mertins

in: Journal of Economics & Management Strategy, forthcoming

Abstract

By conducting a natural field experiment, we analyze the managerial policy of delegating the wage choice to employees. We find that this policy enhances performance significantly, which is remarkable since allocated wage premiums of the same size have no effect at all. Observed self‐imposed wage restraints and absence of negative peer effects speak in favor of wage delegation, although the chosen wage premium levels severely dampen its net value. Additional experimental and survey data provide important insights into employees' underlying motivations.

Financial Literacy and Self-employment

Aida Ćumurović Walter Hyll

in: The Journal of Consumer Affairs, forthcoming

Abstract

In this paper, we study the relationship between financial literacy and self‐employment. We use established financial literacy questions to measure literacy levels. The analysis shows a highly significant and positive correlation between the index and self‐employment. We address the direction of causality by applying instrumental variable techniques based on information about maternal education. We also exploit information on financial support and family background to account for concerns about the exclusion restriction. The results provide support for a positive effect of financial literacy on the probability of being self‐employed. As financial literacy is acquirable, the findings suggest that entrepreneurial activities might be increased by enhancing financial literacy.

Gender Stereotypes still in MIND: Information on Relative Performance and Competition Entry

Sabrina Jeworrek

in: Journal of Behavioral and Experimental Economics, 2019

Abstract

By conducting a laboratory experiment, I test whether the gender tournament gap diminishes in its size after providing information on the relative performance of the two genders. Indeed, the gap shrinks sizeably, it even becomes statistically insignificant. Hence, individuals’ entry decisions seem to be driven not only by incorrect self-assessments in general but also by incorrect stereotypical beliefs about the genders’ average abilities. Overconfident men opt less often for the tournament and, thereby, increase their expected payoff. Overall efficiency, however, is not affected by the intervention.

Measuring Indirect Effects of Unfair Employer Behavior on Worker Productivity – A Field Experiment

Matthias Heinz Sabrina Jeworrek Vanessa Mertins Heiner Schumacher Matthias Sutter

in: IWH Discussion Papers, No. 26, 2017

Abstract

We present a field experiment in which we set up a call-center to study how the productivity of workers is affected if managers treat their co-workers in an unfair way. This question cannot be studied in long-lived organizations since workers may change their career expectations (and hence effort) when managers behave unfairly towards co-workers. In order to rule out such confounds and to measure productivity changes of unaffected workers in a clean way, we create an environment where employees work for two shifts. In one treatment, we lay off parts of the workforce before the second shift. Compared to two different control treatments, we find that, in the layoff treatment, the productivity of the remaining, unaffected workers drops by 12 percent. We show that this result is not driven by peer effects or altered beliefs about the job or the managers’ competence, but rather related to the workers’ perception of unfair behavior of employers towards co-workers. The latter interpretation is confirmed in a survey among professional HR managers. We also show that the effect of unfair behavior on the productivity of unaffected workers is close to the upper bound of the direct effects of wage cuts on the productivity of affected workers. This suggests that the price of an employer’s unfair behavior goes well beyond the potential tit-for-tat of directly affected workers.
