  1. Sexual orientation discrimination in the labor market against gay men
    Autor*in: Drydakis, Nick
    Erschienen: 2021
    Verlag:  Global Labor Organization (GLO), Essen

    The study replicates the first European field experiment on gay men's labor market prospects in Greece. Utilizing the same protocol as the original study in 2006-2007, two follow-up field experiments took place in 2013-2014 and 2018-2019. The study... mehr

    The study replicates the first European field experiment on gay men's labor market prospects in Greece. Utilizing the same protocol as the original study in 2006-2007, two follow-up field experiments took place in 2013-2014 and 2018-2019. The study estimated that gay men experienced occupational access constraints and wage sorting in vacancies offering lower remuneration. It was found that in 2013-2014 and 2018-2019, gay men experienced increasingly biased treatment compared to 2006-2007. Moreover, the results suggested that unemployment bore an association with occupational access constraints and wage sorting in vacancies offering lower remuneration for gay men. In each of the three experiments, this study captured recruiters' attitudes toward gay men. A one standard deviation increase in taste-discrimination attitudes against gay men decreased their access to occupations by 9.6%. Furthermore, a one standard deviation increase in statistical-discrimination attitudes against gay men decreased their access to occupations by 8.1%. According to the findings, in 2013-2014 and 2018-2019, firms excluding gay applicants expressed a higher level of taste- and statistical-discrimination attitudes compared to 2006-2007. A gay rights backlash due to the LGBTIQ+ group's attempt to advance its agenda, rising far-right rhetoric, and prejudice associated with economic downturns experienced in Greece might correspond with increasing biases against gay men.

    We replicate Meissner (2016) where debt aversion was reported for the first time in an intertemporal consumption and saving problem. While Meissner (2016) uses a German sample, our subjects are US undergraduate students. All of the main findings from the original study replicate, with similar effect sizes. Additionally, we extend the original analysis by correlating a new individual index of debt aversion on individual characteristics such as gender, cognitive ability, and risk aversion. The findings suggest that gender and risk aversion are not correlated with debt aversion. However, cognitive ability is positively correlated with debt aversion. Overall, this paper confirms the importance of debt aversion in intertemporal consumption problems and validates the approach of Meissner (2016).

    Reanalyses of empirical studies and replications in new contexts are important for scientific progress. Journals in economics increasingly require authors to provide data and code alongside published papers, but how much does the economics profession indeed replicate? This paper summarizes existing replication definitions and reviews how much economists replicate other scholars’ work. We argue that in order to counter incentive problems potentially leading to a replication crisis, replications in the spirit of Merton’s ‘organized skepticism’ are needed – what we call ‘policing replications’. We review leading economics journals to show that policing replications are rare and conclude that more incentives to replicate are needed to reap the fruits of rising transparency standards.

    We conduct a replication of Settele (2022), a online survey experiment designed to find out how individual's beliefs about the gender wage gap affect their policy preferences. We reproduce Results 1 and 2 of the study: how prior beliefs around the wage gap are distributed among individuals and how a information treatment causally affects the policy demand. Our re-coded replication shows that the reported results are robust.

    Replication and constructive controversy are essential for scientific progress. This paper reviews the impact of all replications published as comments in the American Economic Review between 2010 and 2020. We investigate the citation rates of comments and whether a comment affects its original paper’s citation rates. We find that most comments are barely cited, and they have no impact on the original papers’ subsequent citations. This finding holds for original papers for which the comment diagnoses a substantive problem. We conclude from these citation patterns that replications do not update the economics literature. In an online opinion survey, we elicited viewpoints of both comment authors and original authors and find that in most cases, there is no consensus regarding the replication’s success and to what extent the original paper’s contribution sustains. This resonates with the conventional wisdom that robustness and replicability are hard to define in economics. Replikation und konstruktive Debatten sind für den wissenschaftlichen Fortschritt unerlässlich. Dieses Papier untersucht die Auswirkungen aller Replikationen, die zwischen 2010 und 2020 als Kommentare (engl. Comments) im American Economic Review erschienen sind. Wir untersuchen die Zitationen von Kommentaren und ob sich die Veröffentlichung eines Kommentars auf die Zitationen des Originalartikels auswirkt. Wir stellen fest, dass die meisten Kommentare kaum zitiert werden, und dass sie keinen Einfluss auf die nachfolgenden Zitationen der Originalartikel haben. Dieses Ergebnis gilt auch für Originalartikel, bei denen der Kommentar ein gravierendes inhaltliches Problem diagnostiziert. Wir schließen aus diesen Zitationsmustern, dass Replikationen die wirtschaftswissenschaftliche Literatur nicht aktualisieren. In einer Online-Umfrage haben wir die Meinungen der Autoren von Kommentaren und Originalartikeln eingeholt. Wir haben festgestellt, dass in den meisten Fällen weder Konsens über das Ergebnis der Replikation besteht, noch ob der Beitrag der Originalartikel weiterhin Gültigkeit hat. Dies deckt sich mit der gängigen Meinung, dass Robustheit und Replizierbarkeit in den Wirtschaftswissenschaften schwer zu definieren sind.

    Bosch-Domènech et al. (2014) reported a negative association between 2D:4D, a suggested marker of prenatal testosterone exposure, and the Cognitive Reflection Test (CRT) in a sample of 623 university students. In this pre-registered study, we test whether we can replicate their findings in a general population sample of over 2,500 individuals from Germany. We find no statistically significant association between 2D:4D and the CRT in any of our primary hypothesis tests, or in any of our pre-registered exploratory analyses and robustness tests. The evidence is strong (based on the 99.5% confidence intervals in all three primary hypotheses tests) against effect sizes in the hypothesized direction larger than 0.075 CRT units (0.073 of the CRT standard deviation) for a one standard deviation change in 2D:4D.

    This paper revisits the instrumental variable (IV) approach in Lipscomb et al. (2013, 2021, LMB) to study the impacts of electrification. We first make corrections to the construction of the dataset, including the modelled IV. Revised estimates on main outcomes and mechanisms are statistically insignificant, with substantially lower effect sizes. We second develop a framework that accounts for weak IVs and discourages specification screening. Applying it to LMB, we find that most theoretically justified specifications yield insignificant results. The proposed framework is transferable to other IV applications to reduce potential bias stemming from researcher’s or replicator’s discretion. In diesem Papier replizieren wir den Instrumentvariablen-Ansatz (IV) von Lipscomb et al. (2013, 2021) zur Untersuchung der Wirkungen von Elektrifizierung. Wir nehmen zunächst Korrekturen an der Konstruktion des Datensatzes vor, einschließlich der modellierten IV. Die revidierten Schätzungen für die wichtigsten Ergebnisse und Mechanismen der Studie sind statistisch nicht signifikant, mit wesentlich geringeren Effektgrößen. Zweitens entwickeln wir einen Analyserahmen, der schwache IVs berücksichtigt und es erleichtert, Spezifikations-Screening zu vermeiden. Wir stellen bei der Anwendung dieses Analyserahmens fest, dass die meisten theoretisch berechtigten Spezifikationen im Falle von Lipscomb et al. nicht signifikante Ergebnisse liefern. Der vorgeschlagene Analyse-Rahmen ist auf andere Arten von IV-Anwendungen übertragbar, um potenzielle Verzerrungen aufgrund von Ermessensspielräumen auf Seiten der Forschenden und auch Replikatoren zu reduzieren.

    The politically motivated replacement in local governments is a pervasive fact in our modern democracies. Whether it has causal effects on the quality of public services, such as education, is a critical question and yet understudied. This paper uses a regression discontinuity design (RDD) for close elections to replicate Akthari, Moreira and Trucco (2022) who find negative effects on the quality of public education in Brazil (.05-.08 standard deviations of lower test scores). I first reproduce these main results, finding minor computational differences that have no effect on the conclusions. I also show that the estimates for Brazil are in general robust to different specifications following Brodeur, Cook and Heyes (2020). Finally, I implement the same RDD framework now applied to Chilean administrative records to find null effects on test scores. Taken together, these results suggest that political turnover has weakly negative effects on service quality.

    The relationship between social status and ethical behavior is a widely debated topic in research. In their study, Gsottbauer et al. (2022b) investigate whether higher socio-economic status is linked to lower ethical behavior, using data from two large survey experiments involving over 11,000 participants. In this replication project, we test the computational reproducibility and robustness to the replication of their study, using the provided data and code from the replication package (Gsottbauer et al., 2022a). Nearly all the figures and tables were reproducible - in the process of reproducing the results, some minor rounding or transcription errors were discovered. In testing the robustness replicability, we find consistent results for our extensions. The effort for the replication was manageable, even though the authors treat categorical variables as numeric, or use manually-coded interaction variables (i.e. in regression models). In summary, we applaud the transparency of Gsottbauer et al. (2022b) in facilitating replications, and make some general recommendations for further improvements for data-analysis studies.

    Görtz et al. (2022) estimate the effects of innovations to future total factor productivity (TFP) on financial markets. In a Bayesian vector autoregression, they identify a TFP news shock as one that explains the largest share of 40-quarter ahead forecast error variance (FEV) of TFP. Their estimated impulse responses functions show that a positive news shock significantly decreases credit market spreads and increases credit market supply. They also find that a shock that explains the maximum of the FEV of the "excess bond premium" (EBP) (Gilchrist and Zakrajsek 2012) causes similar responses. These results are consistent with an estimated DSGE model with financial frictions. We estimate the main IRFs of the study using the original data and a frequentist estimation approach. We obtain similar point estimates for the dynamic responses to TFP news and EBP max-share shocks. We also update their macroeconomic and financial time series, as some of the data has been revised substantially since their original estimate. We use the updated data to re-estimate the above-mentioned IRFs, and we find that the results are robust to this change in the data. Finally, we investigate the computational reproducibility of their DSGE results, and find that their provided code (consistent with warnings in their README file) does not execute in the most recent version of Dynare or Matlab. Using the version indicated in their replication files, we encounter issues estimating the posterior mode.

    Dickens (2022) studies the role of trade on long-run inter-ethnic linguistic differences. He establishes that neighboring ethnolinguistic groups have smaller (lexicostatistical) linguistic distances when there is a larger agricultural productivity variation between them. Specifically, he establishes that pre-1500 land productivity variation (CSI SD) and its change due to Columbian Exchange in the post-1500 (CSI SD CHANGE) era decrease linguistic distances between groups. In what can be considered his main specification, which includes geographical controls, spatial controls, and language family fixed effects (Table 1 column 5), he estimates that a one standard deviation increase in the change in land productivity variation (post-1500) decreases linguistic distances by 0.11 standard deviations (p-value < 0.01) and a one standard deviation increase in land productivity variation (pre-1500) decreases linguistic distances by 0.06 standard deviations (p-value = 0.12) We conduct a direct replication of the paper by (i) reconstructing the main independent variables using the same original sources and following the procedures explained in the original study, (ii) using an updated version of the linguistic map (Ethnologue v17 instead of v16), and (iii) constructing alternative measures of inter-ethnic potential gains from trade. Our results basically confirm the sign, magnitude, and statistical significance of the point estimates in the original study.

    This paper reviews the impact of replications published as comments in the American Economic Review between 2010 and 2020. We examine their citations and influence on the original papers' subsequent citations. Our results show that comments are barely cited, and they do not affect the original paper's citations - even if the comment diagnoses substantive problems. Furthermore, we conduct an opinion survey among replicators and authors and find that there often is no consensus on whether the original paper's contribution sustains. We conclude that the economics literature does not self-correct, and that robustness and replicability are hard to define in economics.

    Bold et al. (2022b) investigate the effect of providing access to a larger, centralized market where quality is rewarded with a premium on farm productivity and framing incomes from smallholder maize farmers in western Uganda, using a series of randomized experiments and a difference-in-differences approach. We successfully reproduce the results of this study using the publicly provided replication packet. Then test the robustness of these results by re-defining treatment and outcome variables, testing for model misspecification and the leverage of outliers, and testing for non-random selection in the Fisher-permutation process. Our results show that the findings in Bold et al. (2022b) are robust to a variety of decisions in the research process. This evokes confidence in the internal validity of the findings.

    Bauer et al. (2022) derive market-based monetary policy uncertainty and uncover an 'FOMC uncertainty cycle' characterized by a fall of uncertainty after FOMC announcements and its subsequent built-up. Then, the authors show that the financial markets' response to monetary policy announcements depends on the level of short-rate uncertainty on the day before the FOMC announcement. First, we reproduced the paper's findings, though with Matlab version-specific issues. Second, we tested the robustness of the two main results of the paper. We show that the uncertainty cycle in the monetary policy uncertainty is confirmed when the crisis period is included in the sample or when the median instead of the average of changes in the monetary policy uncertainty is considered. However, the FOMC uncertainty cycle does not appear when the monetary policy uncertainty index (Husted et al. 2020) or the daily economic policy uncertainty index (Baker et al. 2016) are used as uncertainty proxies.

    Henry, Zhuravskaya, and Guriev (2022) examine whether people are willing to share "alternative facts" espoused by right-wing populist parties before the 2019 European elections in France and how this interacted with the availability of fact-checking information. They find that both imposed and voluntary fact-checking reduce the likelihood of sharing false statements by approximately 45%, and that imposed and voluntary fact-checking have similar effect sizes. We reproduce these findings and introduce several alternative estimates to assess the robustness of the original results, including resolving an inconsistency in the handling of pre-treatment controls. Overall, our results align with the results of the original paper. The differences we find are small in absolute magnitude but, since many effects were small, not always trivial in terms of relative differences. This replication supports the conclusions of the original paper.

    Xu (2022) estimates the causal impact of bank failures on the level of trades with a staggered difference-in-differences design and an IV strategy with Bartik instrument, using the 1866 banking crisis as a quasi-natural experiment. Findings, based on historical data on the trades and loans between London banks and banks around the world, show that countries exposed to bank failures in London immediately exported significantly less and did not recover their lost growth relative to unexposed places. Moreover, the effect lasted for decades. First, we reproduce the paper's main findings by running the original code and uncover three issues, one of which that slightly affects the main estimates reported in the study. Second, we test the robustness of the results to (1) removing weights from the regressions, (2) using a spatial HAC correction for the standard errors, and (3) implementing a method for possibly heterogeneous treatment effects with a staggered difference-indifferences design. Overall, we conclude that the main findings are valid and robust.

    Leininger et al. (2023) study the political consequences of temporary disenfranchisement. Taking advantage of differentiated voting elegibility thresholds applying in different elections in Germany, they analyze how first-time voters react when losing eligibility in a follow-up election. They exploit this setting in a difference-in-differences design using panel data. They find that temporary disenfranchisement decreases perceived external efficacy by 0.19 points on a five-point Likert scale and satisfaction with democracy by 0.14 points. Both results are statistically significant at the five-percent level. In contrast, internal efficacy and political interest remain unaffected by the treatment, and regaining voting eligibility is not associated with statistically significant changes in respondents' attitudes. This report focuses on the computational reproducibility and robustness replicability of these findings. To assess the paper's reproducibility, we first attempt to reproduce the paper's estimates and figures using the author's replication materials. In a second step, we perform several robustness checks by means of alternative difference-in-differences specifications using coarsened exact matching and entropy balancing, and a closer examination of panel attrition. Overall, we find complete reproducibility of the original replication materials. Our robustness checks confirm the sign congruence and significance of coefficients reported in the original paper. We raise the issue of potential bias due to differential panel attrition rates between treated and untreated respondents.
