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.

When the Meaning of Work Has Disappeared: Experimental Evidence on Employees’ Performance and Emotions
Adrian Chadi, Sabrina Jeworrek, Vanessa Mertins
Management Science,
Nr. 6,
2017
Abstract
This experiment tests for a causal relationship between the meaning of work and employees’ motivation to perform well. The study builds on an existing employer–employee relationship, adding realism to the ongoing research of task meaning. Owing to an unexpected project cancelation, we are able to study how varying the information provided about the meaning of previously conducted work — without the use of deception, but still maintaining a high level of control — affects subsequent performance. We observe a strong decline in exerted effort when we inform workers about the meaninglessness of a job already done. Our data also suggests that providing a supplemental alternative meaning perfectly compensates for this negative performance effect. Individual characteristics such as reciprocal inclinations and trust prompt different reactions. The data also show that the meaning of work affects workers’ emotions, but we cannot establish a clear relationship between emotional responses and performance.

On Modeling IPO Failure Risk
Gonul Colak, Mengchuan Fu, Iftekhar Hasan
Economic Modelling,
April
2022
Abstract
This paper offers a novel framework, combining firm operational risk, IPO pricing risk, and market risk, to model IPO failure risk. By analyzing nearly a thousand variables, we observe that prior IPO failure risk models have suffered from a major missing-variable problem. Evidence reveals several key new firm-level determinants, e.g., the volatility operating performance, the size of its accounts payable, pretax income to common equity, total short-term debt, and a few macroeconomic variables such as treasury bill rate, and book-to-market of the DJIA index. These findings have major economic implications. The total value loss from not predicting the imminent failure of an IPO is significantly lower with this proposed model compared to other established models. The IPO investors could have saved around $18billion over the period between 1994 and 2016 by using this model.

Commitment or Constraint? The Effect of Loan Covenants on Merger and Acquisition Activity
Gene Ambrocio, Gonul Colak, Iftekhar Hasan
Finance Research Letters,
June
2022
Abstract
We investigate how loan covenants associated with potential target firms affect takeover deals. We propose two possible channels. Under a discipline channel, the target firm becomes an attractive candidate for takeovers and merger deals are facilitated. Under a constraint channel, covenants hinder merger activity. We find support for the latter channel. Takeover likelihood is lower, deal failures are more common, the likelihood of price renegotiation is higher, and acquisition premium is lower when the target is bound by covenants. Covenant tightness exacerbates this effect.

Productivity, Managers’ Social Connections and the Financial Crisis
Iftekhar Hasan, Stefano Manfredonia
Journal of Banking and Finance,
August
2022
Abstract
This paper investigates whether managers’ personal connections help corporate productivity to recover after a negative economic shock. Leveraging the heterogeneity in the severity of the financial crisis across different sectors, the paper reports that (i) the financial crisis had a negative effect on within-firm productivity, (ii) the effect was long-lasting and persistent, supporting a productivity-hysteresis hypothesis, and (iii) managers’ personal connections allowed corporations to recover from this productivity slowdown. Among the possible mechanisms, we show that connected managers operating in affected sectors foster productivity recovery through higher input cost efficiency and better access to the credit market, as well as more efficient use of labour and capital.

Stock Liquidity and Corporate Labor Investment
Mong Shan Ee, Iftekhar Hasan, He Huang
Journal of Corporate Finance,
February
2022
Abstract
Labor is among the most crucial factors of production that maintain a firm's competitiveness. Given its economic importance, drivers of firms' labor investment policy have gained increasing attention in the financial economics literature. This study investigates the relation between stock liquidity and labor investment efficiency. We establish a causal relation between the two phenomena using an exogenous shock to liquidity: the 2001 decimalization of stock trading. We find that labor investment efficiency improves following an increase in stock liquidity, and the effect is prevalent in firms experiencing overinvestment in labor. Our findings further support the argument that stock liquidity improves the efficiency of labor investment by enhancing governance through shareholder exit threat.

Konjunktur aktuell: Belebung in Dienstleistungsbranchen, aber zunächst weiter schwache Industriekonjunktur
Konjunktur aktuell,
Nr. 2,
2023
Abstract
Im Sommer 2023 deuten Stimmungsindikatoren auf einen weltweiten Aufschwung in den Dienstleistungsbranchen, die Konjunktur im Verarbeitenden Gewerbe bleibt aber schwach. Hohe Inflation und gestiegene Leitzinsen dämpfen die Konjunktur in den meisten Weltregionen. In Europa belasten auch im langjährigen Vergleich hohe Energiepreise. Insgesamt bleibt die Dynamik der Weltwirtschaft im Jahr 2023 verhalten. Die deutsche Wirtschaft wird in mäßigem Tempo expandieren, denn mit sinkender Inflation und erhöhter Lohndynamik wird der private Konsum wieder zulegen. Das Bruttoinlandsprodukt dürfte 2023 um 0,3% zurückgehen, für das kommende Jahr ist ein Zuwachs von 1,7% prognostiziert. Für 2023 ist mit einer Inflationsrate von 6,1% und für 2024 mit 2,7% zu rechnen.

Safety Net or Helping Hand? The Effect of Job Search Assistance and Compensation on Displaced Workers
Daniel Fackler, Jens Stegmaier, Richard Upward
IWH Discussion Papers,
Nr. 18,
2023
Abstract
We provide the first systematic evidence on the effectiveness of a contested policy in Germany to help displaced workers. So-called “transfer companies” (Transfergesellschaften) employ displaced workers for a fixed period, during which time workers are provided with job-search assistance and are paid a wage which is a substantial fraction of their pre-displacement wage. Using rich and accurate data on workers’ employment patterns before and after displacement, we compare the earnings and employment outcomes of displaced workers who entered transfer companies with those that did not. Workers can choose whether or not to accept a position in a transfer company, and therefore we use the availability of a transfer company at the establishment level as an IV in a model of one-sided compliance. Using an event study, we find that workers who enter a transfer company have significantly worse post-displacement outcomes, but we show that this is likely to be the result of negative selection: workers who lack good outside opportunities are more likely to choose to enter the transfer company. In contrast, ITT and IV estimates indicate that the use of a transfer company has a positive and significant effect on employment rates five years after job loss, but no significant effect on earnings. In addition, the transfer company provides significant additional compensation to displaced workers in the first 12 months after job loss.

The Promise and Peril of Entrepreneurship

MIT Press,

Abstract
Startups create jobs and power economic growth. That's an article of faith in the United States—but, as The Promise and Peril of Entrepreneurship reveals, our faith may be built on shaky ground. Economists Robert Fairlie, Zachary Kroff, Javier Miranda, and Nikolas Zolas—working with Census Bureau microdata—have developed a new data set, the Comprehensive Startup Panel, that tracks job creation and the survival of every startup in the country. In doing so, they recalibrate our understanding of how startups behave in the US economy. Specifically, their work seeks to answer three critical questions: How many jobs does each entrepreneur create? Do those jobs disappear quickly? And how long do entrepreneurial enterprises survive?

Abstract
Die Gemeinschaftsaufgabe „Verbesserung der regionalen Wirtschaftsstruktur“ (GRW) ist das wichtigste regionalpolitische Programm in Deutschland und wurde nach der Wiedervereinigung in großem Umfang zur Unterstützung des wirtschaftlichen Transformationsprozesses in den neuen Bundesländern eingesetzt. Ein Überblick über nationale und internationale kausalanalytische Studien zur Wirkung von Investitionszuschüssen zeigt, dass solche Programme positive Effekte auf die Entwicklung insbesondere von Beschäftigung und Einkommen haben. Nicht nur die geförderten Betriebe profitieren von der Unterstützung, sondern die Regionen insgesamt. Auch wenn die Studien nicht bis in die frühen 1990er Jahre zurückreichen, kann man daraus schließen, dass die GRW zur wirtschaftlichen Entwicklung in Ostdeutschland beigetragen hat – und zum Aufholprozess.
