Sign Restrictions, Structural Vector Autoregressions, and Useful Prior Information

Abstract
This paper makes the following original contributions to the literature. (i) We develop a simpler analytical characterization and numerical algorithm for Bayesian inference in structural vector autoregressions (VARs) that can be used for models that are overidentified, just‐identified, or underidentified. (ii) We analyze the asymptotic properties of Bayesian inference and show that in the underidentified case, the asymptotic posterior distribution of contemporaneous coefficients in an n‐variable VAR is confined to the set of values that orthogonalize the population variance–covariance matrix of ordinary least squares residuals, with the height of the posterior proportional to the height of the prior at any point within that set. For example, in a bivariate VAR for supply and demand identified solely by sign restrictions, if the population correlation between the VAR residuals is positive, then even if one has available an infinite sample of data, any inference about the demand elasticity is coming exclusively from the prior distribution. (iii) We provide analytical characterizations of the informative prior distributions for impulse‐response functions that are implicit in the traditional sign‐restriction approach to VARs, and we note, as a special case of result (ii), that the influence of these priors does not vanish asymptotically. (iv) We illustrate how Bayesian inference with informative priors can be both a strict generalization and an unambiguous improvement over frequentist inference in just‐identified models. (v) We propose that researchers need to explicitly acknowledge and defend the role of prior beliefs in influencing structural conclusions and we illustrate how this could be done using a simple model of the U.S. labor market.

Abstract
Ende November 2019 wurde ein neuer Tarifvertrag für die Chemische Industrie abgeschlossen. Dementsprechend steigen die tabellenwirksamen Tariflöhne zum Juli 2020 um 1,5% und ein Jahr später nochmals um 1,3%. Hinzu kommen Einmalzahlungen in Höhe von 4,0% – 6,0% eines Monatsentgelts für die Zeit bis zur ersten Tariferhöhung im Juli 2020. Zusätzlich wurde erstmalig ein tarifliches Zukunftskonto im Gegenwert von zwei Tagen im Jahr 2020, drei Tagen im Jahr 2021 und danach jeweils fünf Tagen je Jahr vereinbart, die als Freizeit genommen, angespart oder ausgezahlt werden können. Dies entspricht einem Plus von 1,8 %. Hinzu kommt eine tarifliche Pflegezusatzversicherung und die Anhebung des Weihnachtsgeldes. Durch diese Zusatzvereinbarungen werden die eher niedrigen tabellenwirksamen Tariflohnsteigerungen erheblich aufgewertet. Insgesamt umfasst der Tariflohnabschluss ein Plus von mehr als 6% für eine Laufzeit von bis zu 29 Monaten.

Abstract
Seit dem Jahr 2009 sind im Grundgesetz neue Verschuldungsgrenzen verankert, nach denen die Bundesländer ab dem Jahr 2020 strukturell ausgeglichene Haushalte vorweisen müssen. Für das Land Hessen ist im Artikel 141 der Landesverfassung bestimmt, dass Einnahmen und Ausgaben des Haushalts des Landes grundsätzlich ohne Kredite auszugleichen sind. Diese Regelung ist erstmals ab dem Haushaltsjahr 2020 anzuwenden. Bei einer Abweichung von der wirtschaftlichen Normallage sind Kreditaufnahmen, ebenso wie in außergewöhnlichen Notfällen, zulässig, sofern die anschließende Rückführung dieser Kredite sichergestellt ist. Mit dem vorliegenden Gesetzentwurf soll die gesetzliche Ausgestaltung der hessischen Schuldenbremse geregelt werden. Zudem soll ein verbindlicher Abbaupfad für die Neuverschuldung bis zum Jahr 2020 festgelegt werden.

Political Influence and Financial Flexibility: Evidence from China
Xian Gu, Iftekhar Hasan, Yun Zhu
Journal of Banking and Finance,
February

Abstract
This paper investigates how political influence affects firms’ financial flexibility and speed of adjustment toward target leverage ratios. We find that at the macro level, firms in environments with high political advantages, proxied by provincial affiliations with heads of state as well as political status and party rank of provincial leaders, adjust faster. At the micro level, firms that are state-owned, have CPC members as executives, or bear low exposure to changes in political uncertainty adjust faster. When interacted, the micro-level political factors have more significant impact.

On the Empirics of Reserve Requirements and Economic Growth

Journal of Macroeconomics,

2019
Abstract
Reserve requirements, as a tool of macroprudential policy, have been increasingly employed since the outbreak of the great financial crisis. We conduct an analysis of the effect of reserve requirements in tranquil and crisis times on long-run growth rates of GDP per capita and credit (%GDP) making use of Bayesian model averaging methods. Regulation has on average a negative effect on GDP in tranquil times, which is only partly offset by a positive (but not robust effect) in crisis times. Credit over GDP is positively affected by higher requirements in the longer run.

Bank Financing, Institutions and Regional Entrepreneurial Activities: Evidence from China
Iftekhar Hasan, Nada Kobeissi, Haizhi Wang, Mingming Zhou
International Review of Economics and Finance,

Abstract
We investigate the effects of bank financing on regional entrepreneurial activities in China. We present contrasting findings on the role of quantity vs. quality of bank financing on small business formation in China: while we document a consistent, significantly positive relationship between the quality of bank financing and new venture formation, we find that the quantity of supplied credit is insignificant. We report that formal institutions are positively correlated to regional entrepreneurial activities, and informal institutions substitute formal institutions. Our findings also reveal that the institutional environment tends to supplement bank financing in promoting regional entrepreneurial activities.

SMEs and Access to Bank Credit: Evidence on the Regional Propagation of the Financial Crisis in the UK
Hans Degryse, Kent Matthews, Tianshu Zhao
Journal of Financial Stability,
2018
Abstract
We study the sensitivity of banks’ credit supply to small and medium size enterprises (SMEs) in the UK with respect to the banks’ financial condition before and during the financial crisis. Employing unique data on the geographical location of all bank branches in the UK, we connect firms’ access to bank credit to the financial condition (i.e., bank health and the use of core deposits) of all bank branches in the vicinity of the firm for the period 2004–2011. Before the crisis, banks’ local financial conditions did not influence credit availability irrespective of the functional distance (i.e., the distance between bank branch and bank headquarters). However, during the crisis, we find that SMEs with banks within their vicinity that have stronger financial conditions faced greater credit availability when the functional distance is close. Our results point to a “flight to headquarters” effect during the financial crisis.

When Arm’s Length is too Far: Relationship Banking over the Credit Cycle
Thorsten Beck, Hans Degryse, Ralph De Haas, Neeltje van Horen
Journal of Financial Economics,
Nr. 1,
2018
Abstract
We conduct face-to-face interviews with bank CEOs to classify 397 banks across 21 countries as either relationship or transaction lenders. We then use the geographic coordinates of these banks’ branches and of 14,100 businesses to analyze how the lending techniques of banks in the vicinity of firms are related to credit constraints at two contrasting points of the credit cycle. We find that while relationship lending is not associated with credit constraints during a credit boom, it alleviates such constraints during a downturn. This positive role of relationship lending is stronger for small and opaque firms and in regions with a more severe economic downturn. Moreover, our evidence suggests that relationship lending mitigates the impact of a downturn on firm growth and does not constitute evergreening of loans.

Relationship Banking and SME Financing: The Case of Wales
Kent Matthews, Hans Degryse, Tianshu Zhao
International Journal of Banking, Accounting and Finance,
Nr. 1,
2017
Abstract
Regional disparities in credit availability across the UK have been highlighted in a series of studies as a factor affecting both new firm starts and small firm growth prospects. This paper suggests that relationship banking might be an important means of attenuating differences in credit availability. The paper focuses on the value of relationship banking to SMEs in Wales in the period following the global banking crisis. The results show that SMEs that had developed a customer-loan relationship with their banks had a lower probability of experiencing a worsened credit outcome than those that did not. The implications of the findings for regional development and financial provision are discussed.
