Financial intermediation,consumption dynamics,and business cycles

The recent financial crisis highlighted the need to deepen our understanding of the impact of the financial intermediation sector on the real economy. We examine the quantitative implications of financial intermediation and firm's financing frictions in explaining the observed cyclical properties of both real and financial variables. We find that a modified version of the financial intermediation framework of Gertler and Karadi (2011) augmented with financing frictions in production does a good job in matching the unconditional moments of financial fluctuations without compromising key real co-movements. Our results are relevant for macro-prudential policy analysis as they underscore the importance of carefully identifying the sources of aggregate fluctuations in models in which financial intermediaries and financial frictions play a non-trivial role.     

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.     

Collateral,labour monitoring and banking accelerator

This paper derives the determination of external finance premium (EFP ) in the context of banking sector profit maximisation behaviour. EFP/credit spread stems from the managerial cost, associated with the intermediation process, of factor payments to collateral and labour services. The stake of entrepreneurs is relevant to determine the EFP on two grounds: (a) the ratio of entrepreneurial net wealth to collateral value influences the total managerial cost; and (b) entrepreneurs' net worth (fraction of total collateral) helps mitigate the EFP from extracting rebate from collateral service. Based on these, we can derive an observationally similar relationship between EFP and entrepreneurial leverage, as in previous studies. This provides a rationale for us to understand the financial friction from a novel perspective. Besides the leverage ratio, the EFP is shown to be determined also by the resource cost of financial intermediation, for which the model generates a mechanism that contains broader ingredients in determining the behaviour of EFP .     

Financial Structure Changes and the Central Bank Policy

In a response to the financial collapse of 2007–2009, central banks overstepped their narrow role of lender of last resort (LLR) and acted as dealers or market-makers of last resort (MMLR). Such an evolution of the central bank policy stems from the endogenous process of growing securities markets, financial innovations, and market-based credit intermediation. This article examines how changes in the structure of the banking and financial system transforms the central bank policy in financial stability. It considers the separation or integration of the LLR and MMLR functions, revisits the debate opposing lend-to-market and lend-to-institution theses, and discusses the LLR standard rule and its transposition to the MMLR rule. Inasmuch as private securities markets and financial innovations determine the structure of the credit system, central banks endogenously adopt the integrated approach, so that the extensive LLR policy prevails.     

Financial Openness in Turkey

The purpose of this paper is to analyse the effects of financial liberalization on the financial and real sectors of the Turkish economy. The process of liberalization began over 15 years ago simultaneously with a stabilization programme that had been designed according to neoclassical model. The implementation addressed first foreign trade, then the domestic financial market and finally foreign capital movements. Contrary to theoretical expectations, the opening of the capital account induced adverse effects on financial intermediation, savings, investment, growth and foreign debt.     

A simple endogenous growth model of financial intermediation with multiplicity and indeterminacy

This paper analyzes the role of financial intermediation in a simple endogenous growth model. The results suggest that multiple endogenous growth paths can exist in connection with various levels of financial development, due to the reciprocal externality between financial and real sectors. According to multiplicity, the growth effects of shocks on the technology of intermediation are opposite, depending on the balanced growth path. Furthermore, transitional dynamics is examined, and reveals that the high equilibrium is a saddle path, while the low-growth is locally stable. Therefore, the model presents local and global indeterminacy. These theoretical results support the large empirical literature on the relationship between financial development and growth which depicts conflicting impacts.

Differences in growth with international capital markets and financial innovation

This paper presents a model in which technological progress affects the productivity of the financial sector. When technological progress moves quicky, the financial intermediation costs are low, which increases the incentives to invest in new technology. This feedback process involves two types of long-run equilibria: one with low financial intermediation costs and high growth, and the other with high financial intermediation costs and low growth. These divergences in growth rates among countries hold even in the presence of international capital markets with free capital mobility, a very unusual result in the endogenous growth literature.     

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.     

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.     

Intermediation costs and capital flows

In this paper, we modify the standard neoclassical model by incorporating financial intermediation in order to deliver returns consistent with the observation that capital primarily flows to middle income countries. We build a static contracting framework where costly intermediation together with an adverse selection problem have quantitatively important effects on capital flows. When intermediation costs are ignored, the model behaves like the neoclassical model in terms of capital returns. However, when intermediation costs are considered, returns to capital in middle income countries could exceed those in poor and rich countries—high costs of intermediation cause poor countries to concentrate their investments in projects with low returns, while the standard neoclassical effect lowers returns in capital-rich countries. When we embed the return function from the static analysis in a two-country dynamic model, there is capital outflow from a poor country that removes capital controls and becomes open. Even though the closed economy dominates in terms of capital employed in production, it is the open economy that dominates in terms of income, consumption and welfare.     

Expectations and forecasting during the Great Depression: Real-time evidence from the business press

How was the Great Depression viewed in real time? This paper yields a new perspective on this question by quantifying the qualitative statements of economic analysts in the business press and at the Federal Reserve Board. We compare the statements of economic analysts about current and future conditions to what actually happened to the American economy in the Great Depression. While Depression-era economic forecasters were able to accurately assess what was happening contemporaneously in the economy, forecasters were persistently optimistic that “the corner had been turned” and that a strong recovery was imminent even as the economy continued to decline. This optimism was based on the use of analogies and forecasting rules-of-thumb of how an economy should behave, which were derived from the experience of previous recessions (Haney, 1931).     

全球金融危机与国际贸易保护:兼与1929-1933年大萧条的比较

全球金融危机爆发后,贸易保护主义悄然在世界范围内蔓延,自由的国际贸易体系受到了强烈的冲击。这种贸易保护主义是否会重蹈1929-1933年大萧条时期世界性贸易战的覆辙?通过对此次金融危机和1929-1933年大萧条时期的国际贸易保护进行比较研究,作者认为由于在危机爆发后可供选择的宏观经济政策工具、国际贸易的约束规则、国际生产体系、国际协调机制和应对金融危机的经验等方面与大萧条时期存在着不同,虽然此次金融危机爆发后有国际贸易保护的趋势,但由此引发1929-1933年大萧条那样的世界性贸易战的可能性较小。然而,国际经济界仍要防微杜渐,采取有利措施来应对贸易保护主义。     

Financial reforms and credit growth in Nigeria: empirical insights from ARDL and ECM techniques

In the last 37 years, Nigeria has undergone several stages of financial reforms with different impacts on the economy. This paper analyses the impact of these financial reforms on credit growth in Nigeria using annual data from 1980 to 2016. The research work hinges on the theoretical underpinning of McKinnon-Shaw hypothesis on the relevance of financial reforms in a lagging economy. Analysing the data with autoregressive distributed lag error correction representation and bounds testing techniques, we find evidence supporting this hypothesis, and specifically that at higher real interest rates there is increased financial intermediation evidenced by credit growth. Other findings are that in the long-run, financial system deposits, inflation rate and per capita GDP are strong asymmetrical predictors of credit growth and real interest rates (the financial reform indicator), while the short-run relationships are indicator-specific. We further show that a long-run cointegration relationship exists between domestic credit and other covariates and likewise between the real interest rate and its regressors.

International Integration,Trade, and the Great Recession

In the wake of the Great Recession, almost all countries suffered a severe and synchronized trade collapse unlike any seen since the Great Depression. To the extent that economic integration fosters trade among countries, this paper examines the role that international integration played in moderating the negative shock caused by the Great Recession on trade. The methodology adopted is a modified gravity model in which we control for the Great Recession, different forms of integration, as well as the interaction between integration and the recession. Measuring integration in three different ways, the findings show that countries that were more integrated fared better in trade – the extent of trade collapse was milder – than less integrated countries. Specifically, Regional Trade Agreement, as a form of trade integration, had a positive and robust effect on trade during the Great Recession. This positive effect is also robust across regions and countries around the world. In a nutshell, countries that are into some form of trade agreements are better-positioned to absorb negative demand-side shocks caused by economic recessions than similar countries without such agreements.     

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.     

America’s flawed paradigm: macroeconomic causes of the financial crisis and great recession

This paper traces the roots of the financial crisis and Great Recession to a flawed U.S. macroeconomic paradigm that was adopted around 1980 with the triumph of neoliberal economics. One flaw concerns the growth model. A second flaw concerns the model of global economic engagement that created a triple economic hemorrhage of spending on imports, manufacturing job losses, and off-shoring of investment. The new growth model hollowed out the economy and relied on growing debt and asset price inflation. As the process deepened the economy needed ever larger bubbles to grow. Financial deregulation and excess kept the model going longer than expected, but it meant the economy experienced a financial crash and deeper collapse when the contradictions finally surfaced. The United States needs a new economic paradigm and a new growth model, but as yet this challenge has received little attention from policymakers or economists.     

The Workout of Banking Crises: A Macroeconomic Perspective

This paper provides a macroeconomic perspective for governmentinterventions in banking crisis. Such crisis occur when a largenumber of banks fail to meet capital requirements or are insolvent.Using a macroeconomic model with financial intermediation, ouranalyis suggests that strict enforcement of capital-adequaterules suffices in prosperous periods. Capital requirements serveas an indicator for crises interventions in critical stateswhich may require interest rate intervention and restructuringof the banking industry. These policies can be reinforced byrandom bailouts and temporary financial relief, with a largepercentage of the costs being covered by current and futureowners of banks. (JEL D41, E4, G2)
