Die Corona-Pandemie hat die Weltwirtschaft im ersten Halbjahr 2020 drastisch einbrechen lassen. Im Sommer wurden viele Aktivitäten aber wiederaufgenommen, und ein großer Teil des Einbruchs dürfte im zweiten Halbjahr wieder wettgemacht werden. Einige wirtschaftliche Aktivitäten wie der Tourismus oder Verkehrsdienstleistungen werden allerdings noch eine Weile eingeschränkt bleiben.

This paper investigates the role of the fiscal and economic record of the incumbent government in shaping the price response of sovereign bonds and stocks to the election outcome in emerging markets and developed countries. For sovereign bonds in emerging markets, we find robust evidence for higher cumulative abnormal returns (CARs) if a government associated with a relatively low primary fiscal balance is voted out of office compared to elections where the fiscal balance was relatively high. This effect of the incumbent government's fiscal record is significantly more pronounced in the presence of high sovereign default risk and strong political veto players, whereas the quality of institutions does not explain differences in effects for different events. We do not find robust effects of the government's fiscal record for developed countries and stocks.

The slowing down of the global economy adds additional challenges to China? economic policies as the country orchestrates its transition to lower resource dependency and higher technology intensity of output. Are policies aimed at technologically advanced sectors the right answer? Drawing from a newly created dataset of firms? balance sheets over the period 1998?2013, matched with patents data until 2009, we uncover that expenditure in innovation had limited effect on boosting productivity, without generating a clear gain in overall productivity for the high-tech sector. As a matter of fact, there is a much higher dispersion in productivity outcomes in firms belonging to the low-technology sectors, which derives from a bunch of champions in those sectors scoring higher productivity dynamics than in the High-technology sectors. The paper finds those barriers to entry and in general, market power of incumbents in the high-tech generate less than optimal resource reallocation, which hampers the overall productivity. Policies should presumably aim at removing such obstacles rather than solely promote innovation expenditure.

Critics of private equity have warned that the high leverage often used in PE-backed companies could contribute to the fragility of the financial system during economic crises. The proliferation of poorly structured transactions during booms could increase the vulnerability of the economy to downturns. The alternative hypothesis is that PE, with its operating capabilities, expertise in financial restructuring, and massive capital raised but not invested ("dry powder"), could increase the resilience of PE-backed companies. In their study of PE-backed buyouts in the U.K. - which requires and thereby makes accessible more information about private companies than, say, in the U.S. - the authors report finding that, during the 2008 global financial crisis, PE-backed companies decreased their overall investments significantly less than comparable, non-PE firms. Moreover, such PE-backed firms also experienced greater equity and debt inflows, higher asset growth, and increased market share. These effects were especially notable among smaller, riskier PE-backed firms with less access to capital, and also for those firms backed by PE firms with more dry powder at the crisis onset. In a survey of the partners and staff of some 750 PE firms, the authors also present compelling evidence that PEs firms play active financial and operating roles in preserving or restoring the profitability and value of their portfolio companies.

Finance has seen a spectacular growth in innovation and internationalization during the 20th century (Lane and Milesi-Ferretti, 2008; Shiller, 2013), resulting in a complex and highly interconnected network of financial entities spanning across jurisdictions (Allen and Gale, 1994; Popov and Udell, 2012). Meanwhile the challenges grow for policymakers to provide a framework which allows for the operation of a stable finan- cial system within their jurisdiction (Merton, 1995; Allen and Gale, 2000; Morrison and White, 2009; Ongena et al., 2013). The global financial crisis highlights that se- vere disruptions in the financial sector spread across jurisdictions (Wiggins and Met- rick, 2015) and can have large negative effects on the real economy (Chodorow-Reich, 2013). To contain systemic risk and contagion in the globalized financial system, sev- eral changes have been applied to the regulatory framework of international financial markets (G20, 2009). Regulatory efforts encompass among others the implementa- tion of macroprudential policies and the introduction of mandatory central clearing of derivatives. This thesis aims to contribute to the understanding of differential effects of financial policy reforms depending on the characteristics of the regulated financial entities and networks.

I show that rising temperatures can detrimentally affect the sovereign creditworthiness of emerging economies. To this end, I collect long-term monthly temperature data of 54 emerging countries. I calculate a country’s temperature deviation from its historical average, which approximates present day climate change trends. Running regressions from 1994m1-2018m12, I find that higher temperature anomalies lower sovereign bond performances (i.e. increase sovereign risk) significantly for countries that are warmer on average and have lower seasonality. The estimated magnitudes suggest that affected countries likely face significant increases in their sovereign borrowing costs if temperatures continue to rise due to climate change. However, results indicate that stronger institutions can make a country more resilient towards temperature shocks, which holds independent of a country’s climate.

Die Weltwirtschaft befindet sich im Sommer 2020 in einer tiefen Rezession. Auslöser ist die Corona-Pandemie: Regierungen haben überall in der Welt eine Vielzahl von Möglichkeiten der Mobilität und des Zusammentreffens von Personen unterbunden. Etwa seit Mai werden die Restriktionen in etlichen Ländern wieder gelockert. Für den zeitlichen Verlauf der Rezession ist neben den Lockerungen vor allem das Krankheitsgeschehen selbst maßgeblich, das in Asien sehr deutlich und in der Europäischen Union spürbar zurückgegangen ist, kaum jedoch in den USA. Alles in allem dürfte der Produktionseinbruch in der Welt im ersten Halbjahr 2020 deutlich tiefer sein als infolge der Finanzkrise im Winterhalbjahr 2008/2009.

The German government launched an unprecedented range of support programmes to mitigate the economic fallout from the Covid-19 pandemic for employees, self-employed, and firms. Fiscal transfers and guarantees amount to approximately €1.2 billion by now and are supplemented by similarly impressive measures taken at the European level. We argue in this note that the pandemic poses, however, also important challenges to financial stability in general and bank resilience in particular. A stable banking system is, in turn, crucial to ensure that support measures are transmitted to the real economy and that credit markets function seamlessly. Our analysis shows that banks are exposed rather differently to deteriorated business outlooks due to marked differences in their lending specialisation to different economic sectors. Moreover, a number of the banks that were hit hardest by bleak growth prospects of their borrowers were already relatively thinly capitalised at the outset of the pandemic. This coincidence can impair the ability and willingness of selected banks to continue lending to their mostly small and medium sized entrepreneurial customers. Therefore, ensuring financial stability is an important pre-requisite to also ensure the effectiveness of fiscal support measures. We estimate that contracting business prospects during the first quarter of 2020 could lead to an additional volume of non-performing loans (NPL) among the 40 most stressed banks ‒ mostly small, regional relationship lenders ‒ on the order of around €200 million. Given an initial stock of NPL of €650 million, this estimate thus suggests a potential level of NPL at year-end of €1.45 billion for this fairly small group of banks already. We further show that 17 regional banking markets are particularly exposed to an undesirable coincidence of starkly deteriorating borrower prospects and weakly capitalised local banks. Since these regions are home to around 6.8% of total employment in Germany, we argue that ensuring financial stability in the form of healthy bank balance sheets should be an important element of the policy strategy to contain the adverse real economic effects of the pandemic.

THE RAPID AND ONGOING PROCESS OF GLOBALIZATION creates profound challenges for firms operating in the market economy. Global integration has increased the size of firms’ product markets and the amount of their competitors, while global production networks and dramatically falling transportation costs redefine the nature of firms’ production activities. Firms that cannot adapt to this new environment decay and are forced to exit the market, whereas firms that successfully cope with those processes of internationalization prosper and capture markets shares from declining and less productive firms (Pavcnik (2002); Melitz (2003); Melitz & Trefler (2012)).

We show that emergency liquidity provision by the Federal Reserve transmitted to non-U.S. banking markets. Based on manually collected holding company structures, we identify banks in Germany with access to U.S. facilities. Using detailed interest rate data reported to the German central bank, we compare lending and borrowing rates of banks with and without such access. U.S. liquidity shocks cause a significant decrease in the short-term funding costs of the average German bank with access. This reduction is mitigated for banks with more vulnerable balance sheets prior to the inception of emergency liquidity. We also find a significant pass-through in terms of lower corporate credit rates charged for banks with the lowest pre-crisis leverage, US-dollar funding needs, and liquidity buffers. Spillover effects from U.S. emergency liquidity provision are generally confined to short-term rates.
