Climate change and business responses: Green Banking as a role modelLecturer: Monowar Mahmood Affiliation: KIMEP University Almaty, Kazakhstan ESF MU Room S306 10:30 AM
The aim of this paper is to describe the dimensions and parameters of the unique nationally coordinated industry-wide ‘green banking model’ developed by the central bank of Bangladesh, and to assess its adaptability as a role model for other countries to combat climate change challenges and promote sustainability practices. The findings of the paper provide empirical evidence of green banking practices implemented by all industry members of the banking sector. It provides effectiveness of such unique nationally coordinated effort in combating global climate change challenges and promote sustainability initiatives in widespread manner.

Daughters and DivorceLecturer: Jan Kabátek Affiliation: University of Melbourne ESF MU ROOM MT205 3:00 PM
What makes couples with daughters more likely to divorce than couples with sons? Using Dutch registry and U.S. survey data, we show that daughters are associated with higher divorce risks, but only when they are 13-18 years old. These age-specific results rule out explanations involving overarching son preferences and selection. Our findings are consistent with causal mechanisms involving relationship dynamics in families with teenage children. Survey evidence buttresses this interpretation. Subsample analyses show that the magnitude of the effect is linked to parental gender norms and that the effect is absent for fathers who grew up with sisters.
How to fix the existing copyright enforcementLecturer: Lenka Fiala Affiliation: Tilburg University S308 1:00 PM • 5/22/2018
Whether it is copyright infringement, hate speech or terrorist content, Internet intermediaries like Facebook, Twitter or YouTube are expected to essentially do the government's job -- enforcing the law. The legal scheme under which a lot of such delegated enforcement takes place is often referred to as notice \& takedown. According to empirical evidence, it leads to over-notification, over-compliance by providers and under-assertion of rights by affected content creators. We re-create these existing problems in a laboratory and then test a mechanism to address two of them: the overcompliance by providers, and the lack of complaints by creators. Through experiment, we show that our proposed solution gives more power to the users, who realize higher profits due to an improved accuracy of providers' assessment of content and leads to a significant reduction in over-compliance by providers.
Coordination and focal points under time pressure: Experimental evidenceLecturer: Axel Sonntag Affiliation: University of Vienna, Institute for Advanced Studies ESF MU, Room S309 1:00 PM • 5/16/2018
We experimentally examine the effects of varying time pressure on the likelihood that two players coordinate on a label salient focal point in a coordination game. We consider both payoff-symmetric and payoff-asymmetric coordination games. In symmetric games there are no effects of time pressure on overall earnings and efficiency, since almost everyone coordinates on the focal point, regardless of how much time they have to decide. In asymmetric games we observe that higher time pressure only weakly significantly increases overall coordination, but it becomes significantly more likely that any coordination is on the focal outcome, so changes in time pressure also affect the distribution of the surplus.
The Human Capital Cost of Radiation: Long-run Evidence from Exposure outside the WombLecturer: Benjamin Elsner Affiliation: University College Dublin and IZA ESF MU, Room S308 2:30 PM • 5/15/2018
This paper studies the long-term effect of radiation on cognitive skills. We use regional variation in nuclear fallout caused by the Chernobyl disaster in 1986, which led to a permanent increase in radiation levels in most of Europe. To identify a causal effect, we exploit the fact that the degree of soil contamination depended on rainfall within a critical ten-day window after the disaster. Based on unique geo-coded survey data from Germany, we show that people who lived in highly-contaminated areas in 1986 perform significantly worse in standardized cognitive tests 25 years later. This effect is driven by the older cohorts in our sample (born before 1976), whereas we find no effect for people who were first exposed during early childhood. These results are consistent with radiation accelerating cognitive decline during older ages. Moreover, they suggest that radiation has negative effects even when people are first exposed as adults, and point to significant external costs of man-made sources of radiation.
Research findings from the global WageIndicator web survey on work and wagesLecturer: Kea Tijdens Affiliation: AIAS and University of Amsterdam ESF MU, Room S309 1:00 PM • 5/3/2018
On its websites WageIndicator invites web visitors to complete a survey on work and wages. This multi-country, multilingual survey is posted continuously in all 92 countries with a national WageIndicator website. These websites are frequently visited by people looking for information about wages, labour law, collective agreements, and alike (almost 40 million visitors in 2017). The data of the web survey has been used to analyse a range of topics. A study of health workers showed that the main migration pattern is to countries where the same language is spoken, followed by migration to neighbouring and former colonizing countries. Out-migrated health workers earn more and work fewer hours than comparable workers in source countries. Another study showed that wage dispersion among observationally similar workers is due to the intensity of tasks within occupations, though workers in high-wage occupations are less defined around a typical worker than those in other occupations. Other findings relate to variation in collective bargaining coverage, the gender pay gap, the structure of minimum wages around the world, self-identification of occupation in web surveys, and an informality-index for Sub-Saharan countries.

Stigma and prisonersLecturer: Václav Korbel Affiliation: Charles University in Prague ESF MU, Room S309 1:00 PM • 4/12/2018
Prisoners are often stigmatized after their release which contributes to recidivism. However, little is known if and how much their beliefs are affected already before release: if a feeling of stigma arises during incarceration. In a lab-in-the-field experiment, we study if inmates expect to be stigmatized by people outside of prison in a standard trust game (and triple dictator game) and if it is reflected in their trustworthiness. Next, we test if a light-touch psychological intervention — self-affirmation — can mitigate the assumed impact of stigma, looking at the role of risk preferences and competitive confidence. In both games, senders are non-prisoners and receivers are 297 inmates from fifteen medium to high-security Czech prisons. We manipulate if the prison identity is revealed to senders or not, and inmates interact with both types in a within-subject design. Contrary to our expectations, inmates do not feel stigmatized as they expect to receive a higher transfer in the trust game when their prison identity is revealed. It can be fully explained by higher expected altruism in the dictator game. Inmates, however, do not send back more when their identity is revealed. Looking at the heterogeneity across types of prisoners, inmates not participating in any long-term prison-provided treatment drive the differences in beliefs. Unsurprisingly, self-affirmation does not affect trustworthiness nor beliefs when stigma is absent. Our results point to a more nuanced view on the stigmatization of prisoners: even though prisoners may expect statistical discrimination, they do not expect taste-based discrimination.
Criminals on the Field: A Study of College FootballLecturer: Radek Janhuba Affiliation: CERGE-EI ESF MU, Room S309 1:00 PM • 3/22/2018
Economists have found mixed evidence on what happens when the number of police increases. On the one hand, more law enforcers means a higher probability of detecting a crime, which is known as the monitoring effect. On the other hand, criminals incorporate the increase into their decision-making process and thus may commit fewer crimes, constituting the deterrence effect. This study analyzes the effects of an increase in the number of on-field college football officials, taking players as potential criminals and officials as law enforcers. Analyzing a novel play by play dataset from two seasons of college football, we report evidence of a monitoring effect being present in the overall dataset. This effect is mainly driven by offensive penalties which are called in the area of jurisdiction of the added official. Decomposition of the effect provides evidence of the presence of the deterrence effect in cases of penalties with severe punishment or those committed by teams with moderate to high ability, suggesting that teams are able to strategically adapt their behavior following the addition of an official.
Do Gender Quotas Damage Hierarchical Relationships? Evidence from Labor Market ExperimentsLecturer: Joseph Vecci Affiliation: University of Gothenburg ESF MU room MT205 11:00 AM • 3/16/2018
Abstract: Although little is known about the support for gender quotas in hierarchical relationships, they are implemented in many organizations. We conduct a representative survey and a novel set of laboratory experiments to study opinions on gender quotas for managers and how they influence wage setting and worker effort. Our findings reveal that opinions and workplace reactions depend on the environment in which gender quotas are introduced. In our survey, we observe that the approval rating of gender quotas is low if there is no disadvantage against women in the manager selection process, even if they address gender differences in performance. Complementing this evidence, in our experiments we observe that quotas in such environments lead to lower wage and effort levels. However, in an environment where women are disadvantaged because of a biased selection process, we observe a high approval rating for quotas and that they increase wage and effort levels. Our results suggest that it is important to evaluate the existence and nature of disadvantage in the specific labor market before implementing gender quotas.
