Abstract
How important is mastering information and communication technology (ICT) on modern labor markets? We answer this question with unique data on ICT skills tested in 19 countries. Our two instrumental-variable models exploit technologically induced variation in broadband Internet availability that gives rise to variation in ICT skills across countries and German municipalities. We find statistically and economically significant returns to ICT skills. For instance, an increase in ICT skills similar to the gap between an average-performing and a top-performing country raises earnings by about 8 percent. One mechanism driving positive returns is selection into occupations with high abstract task content.

O Brother, Where Start Thou? Sibling Spillovers on College and Major Choice in Four Countries

Abstract
Family and social networks are widely believed to influence important life decisions, but causal identification of those effects is notoriously challenging. Using data from Chile, Croatia, Sweden, and the United States, we study within-family spillovers in college and major choice across a variety of national contexts. Exploiting college-specific admissions thresholds that directly affect older but not younger siblings’ college options, we show that in all four countries a meaningful portion of younger siblings follow their older sibling to the same college or college-major combination. Older siblings are followed regardless of whether their target and counterfactual options have large, small, or even negative differences in quality. Spillover effects disappear, however, if the older sibling drops out of college, suggesting that older siblings’ college experiences matter. That siblings influence important human capital investment decisions across such varied contexts suggests that our findings are not an artifact of particular institutional detail but a more generalizable description of human behavior. Causal links between the postsecondary paths of close peers may partly explain persistent college enrollment inequalities between social groups, and this suggests that interventions to improve college access may have multiplier effects.

Communication instead of conflict – why are female CEOs so interesting for hedge funds
The value of female-led firms is enhanced more by the intervention of activist investors than that of firms with male CEOs. This is the result of a recent paper by Iftekhar Hasan (Fordham University and IWH) and Qiang Wu (Rensselaer Polytechnic Institute, RPI) at the Halle Institute for Economic Research (IWH). "The results show that female CEOs particularly benefit from the intervention of hedge fund activists due to their strong communication and interpersonal skills," explains Iftekhar Hasan. This is because, on average, the intervention of an activist hedge fund increases the value of the firm ex post. To achieve this, activist hedge funds such as Carl Icahn, Trian Fundmanagement or Elliott prefer to rely on communication and cooperation with the management.

International Trade Barriers and Regional Employment: The Case of a No-Deal Brexit
Hans-Ulrich Brautzsch, Oliver Holtemöller
Journal of Economic Structures,
No. 11,
2021
Abstract
We use the World Input–Output Database (WIOD) combined with regional sectoral employment data to estimate the potential regional employment effects of international trade barriers. We study the case of a no-deal Brexit in which imports to the United Kingdom (UK) from the European Union (EU) would be subject to tariffs and non-tariff trade costs. First, we derive the decline in UK final goods imports from the EU from industry-specific international trade elasticities, tariffs and non-tariff trade costs. Using input–output analysis, we estimate the potential output and employment effects for 56 industries and 43 countries on the national level. The absolute effects would be largest in big EU countries which have close trade relationships with the UK, such as Germany and France. However, there would also be large countries outside the EU which would be heavily affected via global value chains, such as China, for example. The relative effects (in percent of total employment) would be largest in Ireland followed by Belgium. In a second step, we split up the national effects on the NUTS-2 level for EU member states and additionally on the county (NUTS-3) level for Germany. The share of affected workers varies between 0.03% and 3.4% among European NUTS-2 regions and between 0.15% and 0.4% among German counties. A general result is that indirect effects via global value chains, i.e., trade in intermediate inputs, are more important than direct effects via final demand.

Cultural Resilience, Religion, and Economic Recovery: Evidence from the 2005 Hurricane Season
Iftekhar Hasan, Stefano Manfredonia, Felix Noth
IWH Discussion Papers,
No. 9,
2021
Abstract
This paper investigates the critical role of religion in the economic recovery after high-impact natural disasters. Exploiting the 2005 hurricane season in the southeast United States, we document that establishments in counties with higher religious adherence rates saw a significantly stronger recovery in terms of productivity for 2005-2010. Our results further suggest that a particular religious denomination does not drive the effect. We observe that different aspects of religion, such as adherence, shared experiences from ancestors, and institutionalised features, all drive the effect on recovery. Our results matter since they underline the importance of cultural characteristics like religion during and after economic crises.

Loneliness during the pandemic – social isolation increases the likelihood of selfish behaviour
Social distancing as a counter-measure to the COVID-19 pandemic has far-reaching social consequences which have so far hardly been discussed from an economic perspective. This is demonstrated in a study by the Halle Institute for Economic Research (IWH). “Experiencing social isolation resulted in the participants in our study making more selfish decisions,” says the author of the study, Sabrina Jeworrek, Assistant Professor at Otto von Guericke University Magdeburg and head of research group in the Department of Structural Change and Productivity at IWH.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior
Sabrina Jeworrek, Joschka Waibel
IWH Discussion Papers,
No. 8,
2021
Abstract
Around the globe, the COVID-19 pandemic has turned daily live upside down since social distancing is probably the most effective means of containing the virus until herd immunity is reached. Social norms have been shown to be an important determinant of social distancing behaviors. By conducting two experiments and using the priming method to manipulate social isolation recollections, we study whether social distancing has in turn affected norms of prosociality and norm compliance. The normative expectations of what behaviors others would approve or disapprove in our experimental setting did not change. Looking at actual behavior, however, we find that persistent social distancing indeed caused a decline in prosociality – even after the relaxation of social distancing rules and in times of optimism. At the same time, our results contain some good news since subjects seem still to care for norms and become more prosocial once again after we draw their attention to the empirical norm of how others have previously behaved in a similar situation.

IWH Bankruptcy Update: Still No Bankruptcy Wave in Sight; Number of Impacted Jobs Reaches New Low
In May the number of corporate bankruptcies once again fell significantly. A jump in June is also unlikely, according to early indicators assessed by IWH. The number of jobs impacted by bankruptcy has fallen to the lowest level witnessed since the Corona outbreak. The IWH Bankruptcy Report, published by the Halle Institute for Economic Research (IWH), provides a monthly update on German bankruptcy statistics.

The Impact of Risk-based Capital Rules for International Lending on Income Inequality: Global Evidence
Iftekhar Hasan, Gazi Hassan, Suk-Joong Kim, Eliza Wu
Economic Modelling,
May
2021
Abstract
This paper investigates the impact of international bank flows from G10 lender countries on income inequality in 74 borrower countries over 1999–2013. Specifically, we examine the role of international bank flows contingent upon the Basel 2 capital regulation and the level of financial market development in the borrower countries. First, we find that improvements in the borrower country risk weights due to rating upgrades under the Basel 2 framework significantly increase bank flows, leading to improvements in income inequality. Second, we find that the level of financial market development is also important. We report that a well-functioning financial market helps the poor access credit and thereby reduces inequality. Moreover, we employ threshold estimations to identify the thresholds for each of the financial development measures that borrower countries need to reach before realizing the potential reductions in income inequality from international bank financing.

Are Credit Rating Disagreements Priced in the M&A Market?
Iftekhar Hasan, He Huang, Thomas To
Journal of International Financial Markets, Institutions and Money,
May
2021
Abstract
This paper examines the effect of credit rating disagreements on merger and acquisition (M&A) decisions. We show that acquirers with split ratings prefer to use stock to finance their acquisitions. More importantly, we find that acquirers with split ratings experience lower announcement returns. Further analysis shows that overpayment by acquirers with split ratings is concentrated in acquirers with entrenched managers. Our results are robust to alternative identification strategies. Overall, our evidence indicates that credit rating disagreements are heavily priced in the M&A market.
