Tips not keptLecturer: Ondřej Dohnal Affiliation: Masaryk University Academic club 12:30 PM • 6/22/2018
Waiters often pool their tips and in some restaurants, waiters do not get to keep their tips, but forfeit them to their employer. We use a variation of the dictator game to explore if and how these scenarios may affect tipping behavior if customers are aware of them. Lab experiment participants are divided into dictators and servers. Servers solve an effort intensive task and earn their dictator a lower or higher amount of money based on their performance (money earned is a proxy for service quality.) In the baseline treatment, dictators then decide if they want to tip their server and how much. In the pooling treatment, dictators decide if and how much to tip their server knowing that the tips will be pooled. In the third treatment, where waiters do not get to keep their tips, dictators choose if and how “big” and expensive a Thank you message to send to their server, knowing he will not receive any of the money it cost.
The effects of corporate social responsibility on labor supply: Evidence from a field experiment with gig-workersLecturer: Tommaso Reggiani Affiliation: Masaryk University Academic club 12:00 PM • 6/22/2018
Tommaso Reggiani (Masaryk University) & Rainer Michael Rilke (WHU - Otto Beisheim School of Management
We investigate the influence of pro-social incentives on workers' labor supply in a natural field experiment. We recruited workers to take part in a survey for a fixed compensation. Having finished the survey, a bonus payment is offered in order to perform an additional optional task. In different treatments, the bonus payment generates (i) a standard private gain, (ii) an equivalent donation or (iii) different combinations of private gain and donation. We observe that high donations in combination with no or only small individual gains lead to negative or null effects on labor supply. Bonus combinations of small donations and generous private gains increase labor supply. Effort provision, as well as job satisfaction, are not systematically affected by the different incentive schemes. The experiment sheds lights on widely accepted claims that corporate philanthropy measures are effective tools to motivate employees. When firms consider the design of pro-social incentives schemes, they should be vigilant about employees' distributional concerns.
Does homeownership hinder labor market activity? Evidence from housing privatization in BrnoLecturer: Štěpán Mikula Affiliation: Masaryk University Academic club 12:15 PM • 6/18/2018
(joint work with Josef Montag)
This paper uses housing privatization in Brno as a quasi-experiment producing exogenous assignment of homeownership status. We do not find homeownership to be causing higher unemployment. In fact, our estimates are consistently negative and economically substantively, ranging from -3 to -8 percentage points. We find no evidence that homeownership lowers labor force participation.
Conventional vs. Digital Vigilante Practices in the Far Right and Anti-Far Right StrategiesLecturer: Radka Vicenová Affiliation: Comenius University, Bratislava ESF ACADEMIC CLUB (Floor -1) 2:00 PM • 11/24/2017
Abstract: The lecture will focus on the concept of vigilantism in the strategies of far right groups in Slovakia as well as in the context of the response from the civil society initiatives. While in the case of far right groups we can see various examples of conventional vigilante strategies used as a tool of political struggle, the civil society is adopting especially diverse digital vigilante practices in order to actively challenge the presence of far right agenda in the public discourse. In both cases, the interaction of online and offline world will be explored, with special attention to the role of the government and state authorities in the equation.
The effect of anchors on task duration estimatesLecturer: Matej Lorko Affiliation: Macquarie Graduate School of Management, Sydney ESF ACADEMIC CLUB (Floor -1) 12:00 PM • 11/24/2017
(Coffee and sandwiches will be available at the seminar)
Abstract: The ability to accurately estimate the duration of planned tasks is the cornerstone of successful time and project management. It is naturally appealing to expect that the accuracy of estimates increases with estimators' professional experience. However, contrary to the intuition, many companies keep estimating over-optimistically. Projects then run late and trigger budget extensions. We hypothesize that project time estimates can be influenced by anchors such as managerial suggestions or customer expectations. Suggestions driven by wishful thinking can cause the estimates to become too optimistic. Moreover, in the absence of estimation feedback, the effect of anchor can persist over time and influence subsequent estimates of the same or similar task. Even when there is no anchor before the first estimate available, the first estimate itself can serve as an anchor for future estimates and cause systematic bias. We experimentally test the influence of numerical anchors on duration estimates of a simple real effort task. In addition, we test the interplay between anchor and task experience by repeating the task estimation and performance process in multiple rounds. We find strong anchoring effects which persist over time. We also find an evidence of a self-anchoring effect.
Old sins cast long shadows: Long-term effects of social capital destruction on residential migrationLecturer: Martin Guzi Affiliation: Masaryk University ESF Room s307 12:50 PM • 11/20/2017
(Cake will be available from 12:40 with the seminar starting promptly at 12:50)
Abstract: The theoretical models suggest there is a negative relationship between social capital and migration (Glaeser et al 2002, David et al 2010, Bräuninger and Tolciu 2011). The simultaneity between investment in social capital and residential mobility decisions leads to an identification problem for empirical analysis. In this paper we exploit the post-war resettlement process in Czechoslovakia as a natural experiment to confirm the causal effect of social capital on residential mobility. After World War II over 3 million Germans (some 29% of the total population in Czech lands) were forcibly expelled leaving behind empty villages and their property. Abandoned lands were swiftly resettled with Czech inhabitants creating new communities in former German villages. Our identification strategy exploits the variation in migration behavior along the historical dividing line between formerly Czech (refereed to as old) and German (new) settlements. For the analysis we employ administrative data on changes of permanent residency in the Czech Republic during 1971–2015. Our results document the enduring effects of social capital destruction in the settlements influenced by the resettlement process. We show a consistently higher migration rates in the new communities vis-a-vis the old communities. A set of falsification tests validates the interpretation of the results.

The Metropolisation Processes – A Case of Central Europe and the Czech RepublicLecturer: Vilém Pařil Affiliation: Masaryk University Academic club 12:00 PM • 5/18/2017
The contribution deals with the strategically important problems of metropolisation. In this context, it presents a theoretically based method of assessment of metropolises, the explanatory power of which was verified on the example of the Central Europe. This method is based on three components: population size (initial assumption), economic profile (ties to economic performance) and general attractiveness (the perception of development potential). The results of the evaluation of the 27 identified metropolises were generalized using a typology of their inclusion within the framework of the listed components: most metropolises were classified as type B – an established metropolis, followed by type C – an elementary metropolis, and type A – a dominant metropolis. A practically targeted conceptualization is then demonstrated on the example of the Czech Republic. The main attention was focused on the intensity of the economic links of Prague (and two further Czech centres) with other Central European metropolises. The corresponding complementary contribution is focused on verification of metropolisation axes on express/highspeed transportation modes.
Do the politicians work for us or someone else?Lecturer: Miloš Fišar Affiliation: Masaryk University Academic Club 12:45 PM • 4/26/2017
