Technical Optimum of Bank Liquidity Creation
Iftekhar Hasan, Jean-Loup Soula
Revue Economique,
Nr. 3,
2022
Abstract
This paper generates a technical optimum of bank liquidity creation benchmark by tracing an efficient frontier in liquidity creation (bank intermediation) and questions why some banks are more efficient than others in such activities. Evidence reveals that medium size banks are most correlated to efficient frontier. Small (large) banks—focused on traditional banking activities—are found to be the most (least) efficient in creating liquidity in on-balance sheet items whereas large banks—involved in non-traditional activities—are found to be most efficient in off-balance sheet liquidity creation. Additionally, the liquidity efficiency of small banks is more resilient during the 2007-2008 financial crisis relative to other banks.

Firm Subsidies, Financial Intermediation, and Bank Risk
Aleksandr Kazakov, Michael Koetter, Mirko Titze, Lena Tonzer
Abstract
We study whether government subsidies can stimulate bank funding of marginal investment projects and the associated effect on financial stability. We do so by exploiting granular project-level information for the largest regional economic development programme in Germany since 1997: the Improvement of Regional Economic Structures programme (GRW). By combining the universe of subsidised firms to virtually all German local banks over the period 1998-2019, we test whether this large-scale transfer programme destabilised regional credit markets. Because GRW subsidies to firms are destabilised at the EU level, we can use it as an exogenous shock to identify bank responses. On average, firm subsidies do not affect bank lending, but reduce banks’ distance to default. Average effects conflate important bank-level heterogeneity though. Conditional on various bank traits, we show that well capitalised banks with more industry experience expand lending when being exposed to subsidised firms without exhibiting more risky financial profiles. Our results thus indicate that stable banks can act as an important facilitator of regional economic development policies. Against the backdrop of pervasive transfer payments to mitigate Covid-19 losses and in light of far-reaching transformation policies required to green the economy, our study bears important implications as to whether and which banks to incorporate into the design of transfer Programmes.

Non-linearity in the Finance-Growth Nexus: Evidence from Indonesia
Nuruzzaman Arsyad, Iftekhar Hasan, Wahyoe Soedarmono
International Economics,
August
2017
Abstract
This paper investigates the finance-growth nexus where bank credit is decomposed into investment, consumption, and working capital credit. From a panel dataset of provinces in Indonesia, it documents that higher financial development measured by financial deepening and financial intermediation exhibits an inverted U-shaped relationship with economic growth. This non-linear effect of financial deepening is driven by both investment credit and consumption credit. These results suggest that too much investment credit and, to a lesser extent, consumption credit are detrimental to economic growth. Ultimately, only financial intermediation associated with working capital credit has a positive and monotonic impact on economic growth.

Time-varying Volatility, Financial Intermediation and Monetary Policy
S. Eickmeier, N. Metiu, Esteban Prieto
IWH Discussion Papers,
Nr. 19,
2016
Abstract
We document that expansionary monetary policy shocks are less effective at stimulating output and investment in periods of high volatility compared to periods of low volatility, using a regime-switching vector autoregression. Exogenous policy changes are identified by adapting an external instruments approach to the non-linear model. The lower effectiveness of monetary policy can be linked to weaker responses of credit costs, suggesting a financial accelerator mechanism that is weaker in high volatility periods. To rationalize our robust empirical results, we use a macroeconomic model in which financial intermediaries endogenously choose their capital structure. In the model, the leverage choice of banks depends on the volatility of aggregate shocks. In low volatility periods, financial intermediaries lever up, which makes their balance sheets more sensitive to aggregate shocks and the financial accelerator more effective. On the contrary, in high volatility periods, banks decrease leverage, which renders the financial accelerator less effective; this in turn decreases the ability of monetary policy to improve funding conditions and credit supply, and thereby to stimulate the economy. Hence, we provide a novel explanation for the non-linear effects of monetary stimuli observed in the data, linking the effectiveness of monetary policy to the procyclicality of leverage.

Is More Finance Better? Disentangling Intermediation and Size Effects of Financial Systems
Thorsten Beck, Hans Degryse, Christiane Kneer
Journal of Financial Stability,
2014
Abstract
Financial systems all over the world have grown dramatically over recent decades. But is more finance necessarily better? And what concept of financial system – a focus on its size, including both intermediation and other auxiliary “non-intermediation” activities, or a focus on traditional intermediation activity – is relevant for its impact on real sector outcomes? This paper assesses the relationship between the size of the financial system and intermediation, on the one hand, and GDP per capita growth and growth volatility, on the other hand. Based on a sample of 77 countries for the period 1980–2007, we find that intermediation activities increase growth and reduce volatility in the long run. An expansion of the financial sectors along other dimensions has no long-run effect on real sector outcomes. Over shorter time horizons a large financial sector stimulates growth at the cost of higher volatility in high-income countries. Intermediation activities stabilize the economy in the medium run especially in low-income countries. As this is an initial exploration of the link between financial system indicators and growth and volatility, we focus on OLS regressions, leaving issues of endogeneity and omitted variable biases for future research.

Government Banking in Russia: Magnitude and New Features
Andrei Vernikov
IWH Discussion Papers,
Nr. 13,
2011
Abstract
State-controlled banks are currently at the core of financial intermediation in Russia. This paper aims to assess the magnitude of government banking, and to reveal some of its special features and arrangements. We distinguish between directly and indirectly state-controlled banks and construct a set of bank-level statistical data covering the period between 2000 and 2011. By January 2011 the market share of state-controlled banks reached almost 54 percent of all bank assets, putting Russia in the same league with China and India and widening the gap from typical European emerging markets. We show that direct state ownership is gradually substituted by indirect ownership and control. It tends to be organized in corporate pyramids that dilute public property, take control away from government bodies, and underpin managerial opportunism. Statecontrolled
banks blur the borderline between commercial banking and development
banking. Dominance of public banks has a bearing on empirical studies whose results might suggest state-owned banks’ greater (or lesser) efficiency or competitiveness compared to other forms of ownership. We tend to interpret such results as influenced by the choice of indicator, period of observations, sample selection, etc., in the absence of an equal playing field for all groups of players. We suggest that the government’s planned retreat from the banking sector will involve non-core assets mainly, whereas control over core institutions will just become more subtle.

Finance and Growth in a Bank-Based Economy: Is It Quantity or Quality that Matters?
Michael Koetter, Michael Wedow
Journal of International Money and Finance,
Nr. 8,
2010
Abstract
Most finance–growth studies approximate the size of financial systems rather than the quality of intermediation to explain economic growth differentials. Furthermore, the neglect of systematic differences in cross-country studies could drive the result that finance matters. We suggest a measure of bank’s intermediation quality using bank-specific efficiency estimates and focus on the regions of one economy only: Germany. This quality measure has a significantly positive effect on growth. This result is robust to the exclusion of banks operating in multiple regions, controlling for the proximity of financial markets, when distinguishing different banking sectors active in Germany, and when excluding the structurally weaker East from the sample.
