Abstract
Using a newly collected dataset at the plant level from 2014 to 2018, we provide the first microscopic portrait of robotization in Germany and study the correlates of robot adoption. Our descriptive analysis uncovers five stylized facts: (1) Robot use is relatively rare. (2) The distribution of robots is highly skewed. (3) New robot adopters contribute substantially to the recent robotization. (4) Robot users are exceptional. (5) Heterogeneity in robot types matters. Our regression results further suggest plant size, high-skilled labor share, exporter status, and labor shortage to be strongly associated with the future probability of robot adoption.

Inflation Concerns and Green Product Consumption: Evidence from a Nationwide Survey and a Framed Field Experiment
Sabrina Jeworrek, Lena Tonzer
IWH Discussion Papers,
Nr. 10,
2024
Abstract
Promoting green product consumption is one important element in building a sustainable society. Yet green products are usually more costly. In times of high inflation, not only budget constraints but also the fear that prices will continue to rise might dampen green product consumption and, hence, limit the effectiveness of exerted efforts to promote sustainable behaviors. To test this suggestion, we conducted a Germany-wide survey with almost 1,200 respondents, followed by a framed field experiment (N=500) to confirm causality. In the survey, respondents’ stated “green” purchasing behavior is, as to be expected, positively correlated with concerns about climate change. It is also negatively correlated with concerns about future inflation and energy costs, but after controlling for observable characteristics such as income and educational level only the correlation with concerns about future prices remains significant. This result is driven by individuals with below-median environmental attitude. In the framed field experiment, we use the priming method to manipulate the saliency of inflation concerns. Whereas sizably relaxing the budget constraint (i.e., by 50 percent) has no impact on the share of organic products in participants’ baskets, the priming significantly decreases the share of organic products for individuals with below-median environmental attitude, similar to the survey data.

IWH-Tarif-Check: Keine realen Netto-Tariflohnzuwächse für Beschäftigte im öffentlichen Dienst der Länder
„Inflationsausgleichszahlung“ und Tariflohnsteigerungen dürften Verbraucherpreisinflation nur knapp ausgleichen.
Die Tarifvertragsparteien des öffentlichen Dienstes der Länder haben sich vor kurzem auf einen neuen Tariflohnabschluss geeinigt: Es wurde vereinbart, dass Einmalzahlungen von insgesamt 3 000 Euro in elf Monatsbeträgen abgabenfrei als so genannte Inflationsausgleichsprämie gezahlt werden. Bereits im Dezember 2023 soll ein Teilbetrag in Höhe von 1 800 Euro ausgezahlt werden, von Januar bis einschließlich Oktober gibt es monatlich jeweils 120 Euro. Die regulären Tabellenentgelte erhöhen sich währenddessen nicht. Erst ab November 2024, wenn die Inflationsausgleichszahlung wegfällt, gibt es eine Stufenerhöhung über 200 Euro für alle Beschäftigten. Auf diese setzt ab Februar 2025 dann eine reguläre prozentuale Erhöhung von 5,5% auf. Der Tarifvertrag läuft bis Ende Oktober 2025.

"Let Me Get Back to You" — A Machine Learning Approach to Measuring NonAnswers
Andreas Barth, Sasan Mansouri, Fabian Wöbbeking
Management Science,
Nr. 10,
2023
Abstract
Using a supervised machine learning framework on a large training set of questions and answers, we identify 1,364 trigrams that signal nonanswers in earnings call questions and answers (Q&A). We show that this glossary has economic relevance by applying it to contemporaneous stock market reactions after earnings calls. Our findings suggest that obstructing the flow of information leads to significantly lower cumulative abnormal stock returns and higher implied volatility. As both our method and glossary are free of financial context, we believe that the measure is applicable to other fields with a Q&A setup outside the contextual domain of financial earnings conference calls.

Poison Bonds
Shuo Xia, Rex Wang Renji
SSRN Discussion Paper,
2023
Abstract
This paper documents the rise of "poison bonds", which are corporate bonds that allow bondholders to demand immediate repayment in a change-of-control event. The share of poison bonds among new issues has grown substantially in recent years, from below 20% in the 90s to over 60% after 2005. This increase is predominantly driven by investment-grade issues. We provide causal evidence that the pressure to eliminate poison pills has led firms to issue poison bonds as an alternative. Further analyses suggest that this practice entrenches incumbent managers, coincidentally benefits bondholders, but destroys shareholder value. Holding a portfolio of firms that remove poison pills but promptly issue poison bonds results in negative abnormal returns of -7.3% per year. Our findings have important implications for understanding the agency benefits and costs of debt: (1) more debt does not necessarily discipline the management; and (2) even without financial distress, managerial entrenchment can lead to conflicts between shareholders and creditors.

Competition and Moral Behavior: A Meta-Analysis of Forty-Five Crowd-Sourced Experimental Designs

Abstract
Does competition affect moral behavior? This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental research protocols. To provide further evidence on whether competition affects moral behavior and to examine whether the generalizability of a single experimental study is jeopardized by design heterogeneity, we invited independent research teams to contribute experimental designs to a crowd-sourced project. In a large-scale online data collection, 18,123 experimental participants were randomly allocated to 45 randomly selected experimental designs out of 95 submitted designs. We find a small adverse effect of competition on moral behavior in a meta-analysis of the pooled data. The crowd-sourced design of our study allows for a clean identification and estimation of the variation in effect sizes above and beyond what could be expected due to sampling variance. We find substantial design heterogeneity—estimated to be about 1.6 times as large as the average standard error of effect size estimates of the 45 research designs—indicating that the informativeness and generalizability of results based on a single experimental design are limited. Drawing strong conclusions about the underlying hypotheses in the presence of substantive design heterogeneity requires moving toward much larger data collections on various experimental designs testing the same hypothesis.
