How financial intermediation impacts on financial stability?

The great financial crisis widened the role of financial intermediation in financial stability. This study develops a new financial intermediation variable, credit cash flow (CCF), which enables measurement of the net financial flow resulting from loan activity. An analysis provides evidence that CCF affects the capital buffer via credit gap behaviour, thus indicating the existence of a channel between the CCF and the capital buffer. Such a link offers the policy-maker the possibility to monitor the behaviour of financial intermediation carried out by banks, in order to avoid the outbreak of financial instability events.     

Financial intermediation with credit constrained agents

This paper studies the effects of financial intermediation on aggregate levels and the distribution of resources in an economy with credit-constrained heterogeneous agents and occupational choice. Whether an agent becomes an entrepreneur depends on a realized entrepreneurial ability and accumulated assets needed to finance a business project with uncertain returns. I compare a steady state of an economy with financial intermediation to an economy in which entrepreneurs must finance their projects only from their savings. The simulated economy with financial intermediation matches well the US data on the distribution of occupations and resources. The steady state welfare and efficiency gains from financial intermediation are large.

Product mix,transactions and cost behaviour: a study of South African bank branches

This paper utilizes microeconomic theory and a panel data set to assess the impact of product mix and transactions on cost behaviour of bank branches in South Africa over the short and long‐term. Estimates of properties of concavity and monotonocity indicate that the cost functions of typical bank branches in South Africa are neither consistent with short‐term nor long‐term cost‐minimizing behaviour. This corroborates earlier findings which indicate that South African banks have low production efficiency and high market power. In addition the cost functions and two production‐output type indices indicate that overall, the intermediation‐output type mix (foreign exchange and custodial services) has a more significant effect on cost behaviour than the production‐output type mix (cheque and deposit accounts). The variety of production‐output type services provided by a branch appears to have limited effect on costs. However the financial value of production‐output type transactions has an impact on costs while the financial value of intermediation type products does not. Branches that provide intermediation‐output type products tend to have higher variable costs – the key determinant of costs is the number of transactions.     

Financial innovation,economic growth,and the consequences of macroprudential policies

We leverage a ‘catch-all’ measure of financial innovation—research and development spending in the financial sector—to assess the net relationship between financial innovation and economic growth and evaluate the influence of macroprudential policy on this relationship. Using a panel of 23 countries over the period of 1996–2014, our results demonstrate a net-positive relationship between financial innovation and gross capital formation. We find no evidence of a net-negative impact of financial innovation on economic growth, challenging the popular and political stigma surrounding financial innovation. We also find little robust evidence of macroprudential policy influencing the relationship between financial innovation and economic growth. Our results support a functional approach to the regulation of financial innovation, which improves the intermediation process, leading to increased capital formation.     

Management Behaviour in Vietnamese Commercial Banks

This study identifies managerial behaviour in Vietnamese banks between the years 2000 and 2014, based on the managerial framework of banks, as identified by Rossi et al. ( 2009 ). This framework is built on the interrelationships between efficiency, risk, capital and diversification. This study uses the Z‐score to measure insolvency risk, the SFA to estimate cost efficiency, the ratio of total equity to total assets to capture bank capital and the HHI index to measure the diversification of revenue and earning assets. The results from the 3SLS estimator indicate that revenue diversification has an insignificant impact on insolvency risk, capital ratio and cost efficiency, but earning assets diversification has a negative effect on these three variables, supporting ‘classical diversification’, ‘economic capital’ and ‘monitoring’ behaviours. Moreover, a decline in cost efficiency leads to a rise in insolvency risk, implying ‘bad management’ behaviour; an increase in risk results in a reduction in cost efficiency, indicating ‘bad luck’ behaviour; and a reduction in capital ratio in the poorly capitalised banks leads to a growth in risk, suggesting ‘moral hazard’ behaviour. The results remain strongly robust when using an alternative risk measurement (the loan loss provision ratio) and an alternative SFA model.     

Corporate financial soundness and its impact on firm performance: implications for corporate debt restructuring in Slovenia

This article studies the extent of corporate leverage and range of excessive debt of Slovenian firms during the recent financial crisis. Half of all firms (of those with some non-zero debt and at least one employee) are found to face an unsustainable debt-to-EBITDA leverage ratio beyond 4, accounting for almost 80% of total outstanding debt. Moreover, a good quarter of all firms experience debt-to-EBITDA ratios exceeding 10 and hold almost half of total aggregate net debt. We then examine how this financial distress affects firm performance in terms of productivity, employment, exports, investment and survival. We find that, while less important during the good times (pre-recession period), lack of firms’ financial soundness during the period of financial distress becomes a critical factor constraining firm performance. The extent of financial leverage and ability to service the outstanding debt are shown to inhibit firms’ productivity growth as well as the dynamics of exports, employment and investment. Micro and small firms are found to suffer relatively more than larger firms from high leverage in terms of export and employment performance during the recession period.     

Inequality and debt in a model with heterogeneous agents

We show that to account for the cross-sectional divergence in debt-to-income ratios in US data a DSGE model must assume a tax reallocation across the top- and bottom-income quantile of the population, rather than differential productivity growth, and low cost of access to financial intermediation.     

Fiscal Policy and Economic Growth: the Role of Financial Intermediation

This paper analyzes the impact of public debt on financial efficiency in an overlapping‐generations model. We argue that public debt may reduce intermediation costs by increasing the collateral of entrepreneurs. This effect is stronger, the stronger the non‐Ricardian component of public debt, i.e. the more it is associated with intergenerational redistribution. This effect can be interpreted as future generations acting as a guarantee for the loans provided to the entrepreneurs of the current generation. Furthermore, multiple growth paths may arise as low taxes increase private collateral, which in turn boosts growth via financial efficiency, while higher growth allows to maintain the same debt/GDP ratio with reduced taxes.     

Optimal portfolio choices using financial leverage

This paper investigates the role of leverage in determining the investor's optimal asset allocation over multiperiod investment horizons. To do this, we allow investors to lever their financial position by borrowing from credit markets. GMM methods are used to estimate and test the optimal portfolio weights and individual's optimal choice of financial leverage. These optimal choices are assumed to be parametric functions of a set of state variables describing the evolution of the economy. The empirical application of this methodology to a portfolio of cash, bonds and stocks reveals that a) financial leverage limits the reaction of investors to changes in the investment opportunity set; b) individuals increase leverage during recessions and deleverage in expansionary periods; c) optimal portfolio weights and financial leverage are negatively related to the degree of investor's risk aversion and positively related to the investment horizon.     

Dollarization and the inflation threshold

Abstract.  Empirical evidence suggests non-linearity in the impact of inflation on financial intermediation and real activity. Evidence also suggests that high inflation affects financial intermediation through the substitution of dollars 'under the mattress' for savings in domestic banks. We model an economy where inflation and real activity are positively related at low levels of inflation. However, when the inflation rate exceeds a threshold, agents substitute dollars for deposits issued by domestic banks, reducing the scale of financial intermediation and investment. As a consequence, at high levels of inflation, capital stock and output become negatively related to the inflation rate.     

Money, credit and banking

In monetary models where agents are subject to trading shocks there is typically an ex post inefficiency since some agents are holding idle balances while others are cash constrained. This problem creates a role for financial intermediaries, such as banks, who accept nominal deposits and make nominal loans. In general, financial intermediation improves the allocation. The gains in welfare come from the payment of interest on deposits and not from relaxing borrowers’ liquidity constraints. We also demonstrate that when credit rationing occurs increasing the rate of inflation can be welfare improving.     

Self-insurance vs. self-financing: A welfare analysis of the persistence of shocks

We study the welfare cost of market incompleteness in a generalized Bewley model where idiosyncratic risk takes the form of entrepreneurial productivity shocks. Market incompleteness in our framework has two dimensions. First, in the Bewley tradition, only a limited set of instruments for consumption smoothing is available. Second, entrepreneurs? capital rental is subject to collateral constraints. As is well known, it is harder to self-insure against more persistent shocks, and the welfare cost of missing consumption insurance increases with shock persistence. On the other hand, with collateral constraints, an increase in shock persistence leads to better allocation of production factors through entrepreneurs? self-financing, and the welfare cost of imperfect capital rental markets decreases with shock persistence. The overall welfare cost of market incompleteness can be increasing, decreasing, or even non-monotone in shock persistence, depending on the relative strengths of its two components—the cost of missing insurance and the cost of imperfect capital markets.     

Costly financial intermediation and excess consumption volatility

This paper documents the cyclical properties of financial intermediation costs and uses their dynamics to explain excess consumption volatility (ECV) differences across countries in a dynamic stochastic general equilibrium framework with housing market. I find that financial development levels have a limited role in explaining ECVs. Instead, the volatility of financial sectors plays the determinative role. Consistent with the data, the model finds higher ECVs in emerging countries. The paper also shows that if the US had the same intermediation cost structure as Turkey, deteriorations in the production and consumption following a financial shock would increase threefold.     

Optimal monetary and macroprudential policies: Gains and pitfalls in a model of financial intermediation

We estimate a quantitative general equilibrium model with nominal rigidities and financial intermediation to examine the interaction of monetary and macroprudential stabilization policies. The estimation procedure uses credit spreads to help identify the role of financial shocks amenable to stabilization via monetary or macroprudential instruments. The estimated model implies that monetary policy should not respond strongly to the credit cycle and can only partially insulate the economy from the distortionary effects of financial frictions/shocks. A counter-cyclical macroprudential instrument can enhance welfare, but faces important implementation challenges. In particular, a Ramsey planner who adjusts a leverage tax in an optimal way can largely insulate the economy from shocks to intermediation, but a simple-rule approach must be cautious not to limit credit expansions associated with efficient investment opportunities. These results demonstrate the importance of considering both optimal Ramsey policies and simpler, but more practical, approaches in an empirically grounded model.     

Configurations of innovation: predictable and maverick modes

This study reports on an investigation of modes of innovation in 43 firms in six industrial sectors: (i) pulp and paper; (ii) computer. services; (iii) pharmaceucticals; (iv) apparel; (v) metallic products; and (vi) financial brokerage services. A model incorporating context, process, strategy, organization and performance variables was built to serve as a base to identify empirical conjfigurations of models of innovation. Configurations are gestalts of variables that describe particular modes of innovative behaviour. The model includes uariables representing context, process, strategy, organization and performance. Modes of innovations were found to he highly sector-specific. In fact, most firms innovate in predictable ways, in conformity with the logic of innovation in their industrial environment. A significant minority of firms, however, adopt maverick behaviours, similar to modes of innovation that prevail in other industries. Modes of innovation thus cut across industry lines as a result of firm's combetencies, competitive situationes or managerial preferences. A taxonomy of modes of innovation cutting across industry lines is presented. The configurations which emerged from the data analysis were: science-based product innovators; (ii) entrepreneurial fast-track experimenters; (iii) global cost leaders; (iv) lethargic reliance on information technology and (v) on process adaptation.     

Assessing macro-financial linkages: A model comparison exercise

The recent global financial crisis has increased interest in macroeconomic models that incorporate financial frictions. We illustrate the simulation properties of five medium-sized general equilibrium models used by central banks in the Eurosystem. The models include a financial accelerator mechanism (convex “spread” costs related to firms' leverage) and/or collateral constraints (based on asset values). We provide results from impulse responses to shocks originating in the financial sector as well as a monetary policy shock. Overall, the models share qualitatively similar and interpretable features. This gives us confidence that we have some common understanding of the mechanisms involved. Finally, we survey recent trends in the literature on financial frictions.     

中国金融脱媒度量及国际比较

本文采用中介化比率和证券化比率两套指标体系从银行、金融部门两个层次以及资产和负债两个方向度量了1978-2007年中国的金融脱媒,并与美国、日本同期的金融脱媒指标进行了比较。结果表明:(1)我国银行业的金融脱媒将贯穿于金融市场发展的整个过程中;(2)中国金融部门的资产方很可能会出现一个中介化比例先下降,之后回调上升的过程,但回调到什么点是有待检验的问题;(3)我国非银行金融机构在吸纳资金、提供资金两方面都的作用都不明显,但考虑到我国在金融市场发展的阶梯上仍处于较低的阶段,未来我国非银行金融机构在吸纳经济中的盈余资金上可能会具有较大的潜力。

The impact of formal financial inclusion on informal financial intermediation and cash preference: evidence from Africa

This paper examines the effect of formal financial intermediation (inclusion) on informal financial intermediation and the use of cash for economic activities. Using data from the Global Findex 2014, we examine whether the use of formal financial intermediaries reduces cash preference and the use of informal financial intermediaries. Our empirical results show that informal financial intermediation is positively associated with formal financial inclusion. This indicates that the relationship between informal and formal financial intermediation is complementary rather than a trade-off, which demonstrates the importance of informal finance plays in the financial system of Africa. Moreover, the use of formal financial intermediaries significantly reduces the preference for holding cash, implying that a robust financial system infrastructure has the potential of mobilizing excess liquidity in the informal economy of Africa for growth and development.
