Macroeconomic consequences of state fragility in sub‐Saharan Africa

Are poor macroeconomic outcomes primarily the result of economic policies, or of deeper underlying state fragility problems in sub‐Saharan Africa? We attempt to answer this question by using carefully specified dynamic panel regression techniques to show how state fragility conditions help to explain the differences in the macroeconomic performance of sub‐Saharan African economies, and to identify the most plausible mechanisms of transmission. We find that countries with greater fragility suffer higher macroeconomic volatility and crisis; they also experience weaker growth. When we disaggregate state fragility into its various components, we find that it is the security and social components that have the strongest causal impact on macroeconomic outcomes, while the political component is, at best, weak. Therefore, we conclude that it is state fragility conditions, and not necessarily macroeconomic policies, that are of first‐order importance in explaining the differences in macroeconomic performance for African countries. The knock‐on effects are mostly mediated through the fiscal channel, the aid channel, and the finance channel. Accordingly, we recommend that interventions in fragile states should best focus on exploiting the potential for using fiscal policy, aid, and finance as instruments to improve macroeconomic outcomes in sub‐Saharan Africa.     

Financial Globalization,Social Exclusion and Financial Crisis

This paper suggests one set of mechanisms that ties financial globalization processes to local dynamics of financial inclusion or exclusion. Specifically, this paper explores the worldwide reconsideration of financial firms’ strategies that has accompanied financial globalization. It is shown that the neoliberal and asymmetric‐information approaches to credit markets and financial crises in developing economies overlook these dimensions of financial globalization because of their tendency to focus on representative credit markets. Banks’ strategic shift has led to the global homogenization and stratification of financial practices—and this in turn has been a key driver of processes of financial exclusion. Financial exclusion then involves bifurcation within financial markets, so that different markets serve different portions of the household and business population. This analysis suggests a reconstruction of Minsky’s microfoundational model of the origins of financial fragility and crisis, which shifts from Minsky’s emphasis on a representative borrower–lender relationship to a situation of borrower–lender relationships in bifurcated markets.     

Optimal Dynamic Capital Requirements

We characterize welfare maximizing capital requirement policies in a quantitative macrobanking model with household, firm, and bank defaults calibrated to Euro Area data. We optimize on the level of the capital requirements applied to each loan class and their sensitivity to changes in default risk. We find that getting the level right (so that bank failure risk remains contained) is of foremost importance, while the optimal sensitivity to default risk is positive but typically smaller than under Basel internal ratings based (IRB) formulas. Starting from low levels, savers and borrowers benefit from higher capital requirements. At higher levels, only savers prefer tighter requirements.     

On the volatility spillover between lslamic and conventional stock markets: A quantile regression analysis

This paper aims at analyzing the degree and structure of interdependencies in terms of volatility (transmission, contagion) between Islamic and conventional stock markets on calm periods and at times of financial fragility and crisis. We focused on the recent financial instability periods and used the Quantile Regression-based GARCH model. Main results lead to very interesting conclusions. First, it has been found that Islamic stock markets are not totally immune to the global financial crisis. Second, a very strong interdependence is sensed from the conventional to the Islamic stock markets, especially, from the conventional developed markets to the Islamic Emerging and Arab markets and to the Islamic developed markets. Finally, it has been proved that the interdependencies from conventional to Islamic markets are propagated between Islamic markets. Our findings suggest that the Islamic finance industry does not seem able to provide cushion against economic and financial shocks that affect conventional markets.     

Financial fragility,sovereign default risk and the limits to commercial bank bail-outs

We show that with intertwined weak banks and weak sovereigns, bank recapitalizations become much less effective. We construct a DSGE model with leverage constrained banks lending to firms and holding domestic government bonds. Bond prices reflect endogenously generated sovereign risk. This introduces a negative amplification cycle: after a credit crisis output losses increase more because higher interest rates trigger lower bond prices and subsequent losses at banks. This further tightens bank leverage constraints, and causes interest rates to rise further. Also bank recapitalizations are then much less effective. Recaps involve swaps of newly issued sovereign bonds for bank equity, the new debt increases sovereign debt discounts, leading to capital losses for the banks on their holdings of sovereign debt that (partially) offset the impact of the recapitalization. The favorable macroeconomic effects of bank recaps on the recovery after a financial crisis are correspondingly lower.     

定向增发、资产注入与股市波动——股权分置改革后的股市脆弱性模型推导及其政策含义

股权分置改革的完成并不能消除上市公司大股东与中小股东之间的利益冲突。在全流通时期,大股东理性参与上市公司的定向增发、资产注入及其后的股份减持很可能诱致股市的过度波动。对这种股市过度波动所引致的股市脆弱性机理我们进行了模型推导和因子分析。分析表明,牛市中,大股东参与定向增发、资产注入会导致牛市的助涨。而当熊市来临时,大股东会停止资产注入并减持股份,进而起到熊市助跌的作用。针对由此引起的股市脆弱性,监管部门应采取相应的监管措施。     

Towards a measure of financial fragility

The paper proposes a measure of financial fragility that is based on economic welfare in a general equilibrium model calibrated against UK data. The model comprises a household sector, three active heterogeneous banks, a central bank/regulator, incomplete markets, and endogenous default. We address the impact of monetary and regulatory policy, credit and capital shocks in the real and financial sectors and how the response of the economy to shocks relates to our measure of financial fragility. Finally we use panel VAR techniques to investigate the relationships between the factors that characterise financial fragility in our model, i.e. banks’ probabilities of default and banks’ profits – to a proxy of welfare.      

试析金融自由化的前提条件

一国金融自由化改革的成功一般应具备四个条件,即稳定的宏观经济环境、金融脆弱性的及时消除、审慎而有效的金融监管以及必要的制度环境建设。这些条件经过各国的实践检验,具有一定的合理性和普遍性。但进行金融自由化改革的前提条件并不绝对,更重要的是应该从本国国情出发,具体情况具体对待,不宜盲目模仿他国。
