European Firm Concentration and Aggregate Productivity
Tommaso Bighelli, Filippo di Mauro, Marc Melitz, Matthias Mertens
Abstract
This article derives a European Herfindahl-Hirschman concentration index from 15 micro-aggregated country datasets. In the last decade, European concentration rose due to a reallocation of economic activity towards large and concentrated industries. Over the same period, productivity gains from reallocation accounted for 50% of European productivity growth and markups stayed constant. Using country-industry variation, we show that changes in concentration are positively associated with changes in productivity and allocative efficiency. This holds across most sectors and countries and supports the notion that rising concentration in Europe reflects a more efficient market environment rather than weak competition and rising market power.

Finance-Growth Nexus and Banking Efficiency: The Impact of Microfinance Institutions
Afsheen Abrar, Iftekhar Hasan, Rezaul Kabir
Journal of Economics and Business,
March-April
2021
Abstract
This paper investigates the relative importance of microfinance institutions (MFIs) at both the macro (financial development, economic growth, income inequality, and poverty) and micro levels (efficiency of traditional commercial banks). We observe a significant impact on most of the fronts. MFIs’ participation increases overall savings (total bank deposits) and credit allocation (loans to private sector) in the economy. Their involvement enhances economic welfare by reducing income inequality and poverty. Additionally, their active presence helps to discipline the traditional commercial banks by subjecting them to more competition triggering higher efficiency.

Private Equity in the Hospital Industry
Janet Gao, Yongseok Kim, Merih Sevilir
ECGI Working Paper,
No. 787,
2021
Abstract
We examine employment and patient outcomes at hospitals acquired by private equity (PE) firms and PE-backed hospitals. While employment declines at PE-acquired hospitals, core medical workers (physicians, nurses, and pharmacists) increase significantly. The proportion of wages paid to core workers increases at PE-acquired hospitals whereas the proportion paid to administrative employees declines. These results are most pronounced for deals where the acquirers are publicly traded PE-backed hospitals. Non-PE-backed acquirers also cut employment but do not increase core workers or reduce administrative expenditures. Finally, PE-backed acquirers are not associated with worse patient satisfaction or mortality rates compared to their non-PE-backed counterparts.

Lack of Selection and Limits to Delegation: Firm Dynamics in Developing Countries
Ufuk Akcigit, Harun Alp, Michael Peters
American Economic Review,
No. 1,
2021
Abstract
Delegating managerial tasks is essential for firm growth. Most firms in developing countries, however, do not hire outside managers but instead rely on family members. In this paper, we ask if this lack of managerial delegation can explain why firms in poor countries are small and whether it has important aggregate consequences. We construct a model of firm growth where entrepreneurs have a fixed time endowment to run their daily operations. As firms grow large, the need to hire outside managers increases. Firms’ willingness to expand therefore depends on the ease with which delegation can take place. We calibrate the model to plant-level data from the U.S. and India. We identify the key parameters of our theory by targeting the experimental evidence on the effect of managerial practices on firm performance from Bloom et al. (2013). We find that inefficiencies in the delegation environment account for 11% of the income per capita difference between the U.S. and India. They also contribute to the small size of Indian producers, but would cause substantially more harm for U.S. firms. The reason is that U.S. firms are larger on average and managerial delegation is especially valuable for large firms, thus making delegation efficiency and other factors affecting firm growth complements.

Public Bank Guarantees and Allocative Efficiency
Reint E. Gropp, Andre Guettler, Vahid Saadi
Journal of Monetary Economics,

2020
Abstract
A natural experiment and matched bank/firm data are used to identify the effects of bank guarantees on allocative efficiency. We find that with guarantees in place unproductive firms receive larger loans, invest more, and maintain higher rates of sales and wage growth. Moreover, firms produce less productively. Firms also survive longer in banks’ portfolios and those that enter guaranteed banks’ portfolios are less profitable and productive. Finally, we observe fewer economy-wide firm exits and bankruptcy filings in the presence of guarantees. Overall, the results are consistent with the idea that guaranteed banks keep unproductive firms in business for too long.

Sovereign Default Risk, Macroeconomic Fluctuations and Monetary-Fiscal Stabilisation
Markus Kirchner, Malte Rieth
IWH Discussion Papers,
No. 22,
2020
Abstract
This paper examines the role of sovereign default beliefs for macroeconomic fluctuations and stabilisation policy in a small open economy where fiscal solvency is a critical problem. We set up and estimate a DSGE model on Turkish data and show that accounting for sovereign risk significantly improves the fit of the model through an endogenous amplication between default beliefs, exchange rate and inflation movements. We then use the estimated model to study the implications of sovereign risk for stability, fiscal and monetary policy, and their interaction. We find that a relatively strong fiscal feedback from deficits to taxes, some exchange rate targeting, or a monetary response to default premia are more effective and efficient stabilisation tools than hawkish inflation targeting.

Finance and Wealth Inequality
Iftekhar Hasan, Roman Horvath, Jan Mares
Journal of International Money and Finance,
November
2020
Abstract
Using a global sample, this paper investigates the determinants of wealth inequality capturing various economic, financial, political, institutional, and geographical indicators. Using instrumental variable Bayesian model averaging, it reveals that only a handful of indicators robustly matters and finance plays a key role. It reports that while financial depth increases wealth inequality, efficiency and access to finance reduce inequality. In addition, redistribution and education are associated with lower inequality whereas wars and openness to international trade contribute to greater wealth inequality.

Activism and Empire Building

Journal of Financial Economics,
No. 2,
2020
Abstract
Hedge fund activists target firms engaging in empire building and improve their future acquisition and divestiture strategy. Following intervention, activist targets make fewer acquisitions but obtain substantially higher returns by avoiding large and diversifying deals and refraining from acquisitions during merger waves. Activist targets also increase the pace of divestitures and achieve higher divestiture returns than matched non-targets. Activists curtail empire building through the removal of empire building chief executive officers (CEOs), compensation based incentives, and appointment of new board members. Our findings highlight an important channel through which activists improve efficiency and create shareholder value.

The Corona Recession and Bank Stress in Germany

No. 4,
2020
Abstract
We conduct stress tests for a large sample of German banks across different recoveries from the Corona recession. We find that, depending on how quickly the economy recovers, between 6% to 28% of banks could become distressed from defaulting corporate borrowers alone. Many of these banks are likely to require regulatory intervention or may even fail. Even in our most optimistic scenario, bank capital ratios decline by nearly 24%. The sum of total loans held by distressed banks could plausibly range from 127 to 624 billion Euros and it may take years before the full extent of this stress is observable. Hence, the current recession could result in an acute contraction in lending to the real economy, thereby worsening the current recession , decelerating the recovery, or perhaps even causing a “double dip” recession. Additionally, we show that the corporate portfolio of savings and cooperative banks is more than five times as exposed to small firms as that of commercial banks and Landesbanken. The preliminary evidence indicates small firms are particularly exposed to the current crisis, which implies that cooperative and savings banks are at especially high risk of becoming distressed. Given that the financial difficulties may seriously impair the recovery from the Covid-19 crisis, the pressure to bail out large parts of the banking system will be strong. Recent research suggests that the long run benefits of largely resisting these pressures may be high and could result in a more efficient economy.
