Networks and the Macroeconomy: An Empirical Exploration
Daron Acemoglu, Ufuk Akcigit, William R. Kerr
NBER Macroeconomics Annual,
2015
Abstract
How small shocks are amplified and propagated through the economy to cause sizable fluctuations is at the heart of much macroeconomic research. Potential mechanisms that have been proposed range from investment and capital accumulation responses in real business-cycle models (e.g., Kydland and Prescott 1982) to Keynesian multipliers (e.g., Diamond 1982; Kiyotaki 1988; Blanchard and Kiyotaki 1987; Hall 2009; Christiano, Eichenbaum, and Rebelo 2011); to credit market frictions facing firms, households, or banks (e.g., Bernanke and Gertler 1989; Kiyotaki and Moore 1997; Guerrieri and Lorenzoni 2012; Mian, Rao, and Sufi 2013); to the role of real and nominal rigidities and their interplay (Ball and Romer 1990); and to the consequences of (potentially inappropriate or constrained) monetary policy (e.g., Friedman and Schwartz 1971; Eggertsson and Woodford 2003; Farhi and Werning 2013).

How Effective is Macroprudential Policy during Financial Downturns? Evidence from Caps on Banks' Leverage
Manuel Buchholz
Working Papers of Eesti Pank,
No. 7,
2015
Abstract
This paper investigates the effect of a macroprudential policy instrument, caps on banks' leverage, on domestic credit to the private sector since the Global Financial Crisis. Applying a difference-in-differences approach to a panel of 69 advanced and emerging economies over 2002–2014, we show that real credit grew after the crisis at considerably higher rates in countries which had implemented the leverage cap prior to the crisis. This stabilising effect is more pronounced for countries in which banks had a higher pre-crisis capital ratio, which suggests that after the crisis, banks were able to draw on buffers built up prior to the crisis due to the regulation. The results are robust to different choices of subsamples as well as to competing explanations such as standard adjustment to the pre-crisis credit boom.

A Review of Empirical Research on the Design and Impact of Regulation in the Banking Sector
Sanja Jakovljević, Hans Degryse, Steven Ongena
Annual Review of Financial Economics,
2015
Abstract
We review existing empirical research on the design and impact of regulation in the banking sector. The impact of each individual piece of regulation may inexorably depend on the set of regulations already in place, the characteristics of the banks involved (from their size or ownership structure to operational idiosyncrasies in terms of capitalization levels or risk-taking behavior), and the institutional development of the country where the regulation is introduced. This complexity is challenging for the econometrician, who relies either on single-country data to identify challenges for regulation or on cross-country data to assess the overall effects of regulation. It is also troubling for the policy maker, who has to optimally design regulation to avoid any unintended consequences, especially those that vary over the credit cycle such as the currently developing macroprudential frameworks.

International Banking and Liquidity Risk Transmission: Evidence from Canada
James Chapman, H. Evren Damar
IMF Economic Review,
No. 3,
2015
Abstract
This paper investigates how liquidity conditions in Canada may affect domestic and/or foreign lending of globally active Canadian banks, and whether this transmission is influenced by individual bank characteristics. It finds that Canadian banks expanded their foreign lending during the recent financial crisis, often through acquisitions of foreign banks. It also finds evidence that internal capital markets play a role in the lending activities of globally active Canadian banks during times of heightened liquidity risk.

Uncertainty, Bank Lending, and Bank-level Heterogeneity
Claudia M. Buch, Manuel Buchholz, Lena Tonzer
IMF Economic Review,
No. 4,
2015
Abstract
We analyze how uncertainty affects bank lending. We measure uncertainty as the cross-sectional dispersion of shocks to bank-level variables. Comparing this measure of uncertainty in banking to more traditional measures of uncertainty, we find similar but no identical patterns. Higher uncertainty in banking has negative effects on bank lending. This effect is heterogeneous across banks: lending by banks that are better capitalized and have higher liquidity buffers tends to be affected less. Also, the degree of internationalization matters, as loan supply by banks in financially open countries is affected less by uncertainty. The impact of the ownership status of the individual bank is less important, in contrast.

Support for Public Research Spin-offs by the Parent Organizations and the Speed of Commercialization
Viktor Slavtchev, D. Göktepe-Hultén
Abstract
We empirically analyze whether support by the parent organization in the early (nascent and seed) stage speeds up the process of commercialization and helps spin-offs from public research organizations generate first revenues sooner. To identify the impact of support by the parent organization, we apply multivariate regression techniques as well as an instrumental variable approach. Our results show that support in the early stage by the parent organization can speed up commercialization. Moreover, we identify two distinct channels - the help in developing a business plan and in acquiring external capital - through which support by the parent organization can enable spin-offs to generate first revenues sooner.

EFN Report Autumn 2015: Economic Outlook for the Euro Area in 2015 and 2016
European Forecasting Network Reports,
No. 4,
2015
Abstract
For the end of this year and for 2016, chances are good that production in advanced economies will continue to expand a bit faster than at trend rates, while growth dynamics in emerging markets economies will not strengthen or even continue to decrease.
Since autumn 2014, production in the euro area expands at an annualized rate of about 1.5%. The recovery appears to be broad based, with contributions from private consumption, exports, and investment into fixed capital, although it fell back in the second quarter after a strong increase at the beginning of the year. From a regional perspective, the recovery is as well quite broad based: production is expanding in almost every country, surprisingly and according to official data, including Greece.
Structural impediments still limit the ability of the euro area economy to grow strongly: firms and, in particular, private households are only slowly reducing their heavy debt burdens.
According to our forecasts, the euro area GDP will grow by 1.6% in 2015 and by 1.9% in 2016. The high increase in the number of refugees in 2015 will, in principle, positively affect private as well as public consumption, but the effect should be below 0.1 percentage points relative to GDP.
Our inflation forecast for 2015 is 0.1%. For 2016, we expect that inflation will increase to 1.3%, which is still below the ECB’s target of 2%.

Banks and Sovereign Risk: A Granular View
Claudia M. Buch, Michael Koetter, Jana Ohls
Abstract
We identify the determinants of all German banks’ sovereign debt exposures between 2005 and 2013 and test for the implications of these exposures for bank risk. Larger, more capital market affine, and less capitalised banks hold more sovereign bonds. Around 15% of all German banks never hold sovereign bonds during the sample period. The sensitivity of sovereign bond holdings by banks to eurozone membership and inflation increased significantly since the collapse of Lehman Brothers. Since the outbreak of the sovereign debt crisis, banks prefer sovereigns with lower debt ratios and lower bond yields. Finally, we find that riskiness of government bond holdings affects bank risk only since 2010. This confirms the existence of a nexus between government debt and bank risk.

Young, Restless and Creative: Openness to Disruption and Creative Innovations
Daron Acemoglu, Ufuk Akcigit, Murat Alp Celik
NBER Working Paper,
No. 19894,
2015
Abstract
This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations—innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation, and on how managers of different ages and human capital are sorted across different firms with different degrees of openness to disruption, we provide firm-level, patent level and cross-country evidence consistent with this pattern. Our measures of creative innovations proxy for innovation quality (average number of citations per patent) and creativity (fraction of superstar innovators, the likelihood of a very high number of citations, and generality of patents). Our main proxy for openness to disruption is the age of the manager - based on the idea that only companies or societies open to such disruption will allow the young to rise up within the hierarchy. Using this proxy at the firm, patent and country level, we present robust evidence that openness to disruption is associated with more creative innovations, but we also show that once the effect of the sorting of young managers to firms that are more open to disruption is factored in, the (causal) impact of manager age on creative innovations is small.

Does Going Public Affect Innovation?
Shai B. Bernstein
Journal of Finance,
No. 4,
2015
Abstract
This paper investigates the effects of going public on innovation by comparing the innovation activity of firms that go public with firms that withdraw their initial public offering (IPO) filing and remain private. NASDAQ fluctuations during the book-building phase are used as an instrument for IPO completion. Using patent-based metrics, I find that the quality of internal innovation declines following the IPO, and firms experience both an exodus of skilled inventors and a decline in the productivity of the remaining inventors. However, public firms attract new human capital and acquire external innovation. The analysis reveals that going public changes firms' strategies in pursuing innovation.
