Analysis of the volatility’s dependency structure during the subprime crisis

In this article, we test the hypothesis of contagion amongst sectors within the United States’ economy during the subprime crisis. The econometric methodology applied here is based on the dynamic conditional correlation model proposed by Engle (2002). Further, we applied several Lagrange multiplier (LM)-robust tests to test whether there were structural breaks in series’ dependency structures during the period of interest. Events theoretically classified as relevant to the crisis upshots as well as the interactions between the moments of the series were used as indicator functions to the referred structural breaks. The main conclusion of this study is that one can indeed observe contagion within almost all pairs of sectors’ indices. Thus, we conclude that the dependency structure of the sectors of interest has faced structural changes during the years of 2007 and 2008. Hence, diversification strategies as well as the risk analysis inherent to the portfolios’ management may have been drastically affected.     

Post-Crisis Experiments in Development Finance Architectures: A Hirschmanian Perspective On ‘Productive Incoherence’

Abstract

The Asian and especially the global crisis of 2008 have catalyzed decentralization of the developing world’s financial governance architecture. I understand this state of affairs via the concept of “productive incoherence” which is apparent in a denser, multilayered development financial architecture that is emerging as a consequence of heterogeneous practical adjustments to changing circumstances rather than as the embodiment of a coherent doctrine. Drawing on Albert Hirschman, I argue that the absence of an encompassing theoretical blueprint for a new economic system—i.e. a new “ism” to replace neoliberalism—is in fact a vitally important virtue. If we cannot live without a new “ism,” I propose “Hirschmanian Possibilism” as a new doctrine—one that rejects an overarching theoretical framework from which to deduce the singly appropriate institutional structure of the economy. Hirschmanian Possibilism asserts instead the value of productive incoherence as a framework for pursuing democratic, ethically viable development institutions.     

Financial market spillovers in transition economies

This paper examines financial market comovements across European transition economies and compares their experience to that of other regions. Correlations in monthly indices of exchange market pressures can partly be explained by direct trade linkages, but not by measures of other fundamentals. Higher-frequency data during three crisis periods reveals the presence of structural breaks in the relationship between exchange-, but not stock markets. While the reaction of markets during the Asian and Czech crises is muted, the pattern of high-frequency spillovers during the Russian crisis looks very similar to that observed in other regions during turbulent times. With greater financial market integration, the financial markets of the more advanced transition economies can be expected to behave more and more like their Asian and Latin American counterparts.     

Effects of Trade and Financial Links on the Transmission of GDP Growth

Using panel analysis of quarterly data from 14 developed countries between 1980 and 2012, I examine the channels by which GDP growth transmission has taken place, and how the transmission of growth has varied with time and global growth. I find that countries with large, open banking sectors and trade deficits tend to transmit growth more strongly than other countries. Transmission effects seem to have become stronger over time and are stronger in periods of slow economic growth.

近年来国际金融危机频发,这些危机的原因除了发生危机的国家的内在因素之外,更主要的还与其外在的整个国际货币金融体系存在着的巨大构造性缺陷息息相关。     

A contribution to the empirics of convergence in real GDP growth: the role of financial crises and exchange-rate regimes

This paper investigates the convergence in real gross domestic product growth focusing on the impact of financial crises (i.e. banking crises, currency crises and debt crises) and nominal exchange-rate regimes (i.e. fixed, intermediate and flexible) on convergence. To that end, we compute four convergence indicators (σ-convergence, γ-convergence, absolute β-convergence and conditional β-convergence) for 163 countries classified into four income groups during the period 1970–2011. The results suggest that (i) there is evidence in favour of σ-convergence and γ-convergence only for high-income countries; (ii) absolute and conditional β-convergence are present in each of the four income groups of the countries under study; (iii) exchange-rate regimes seem to play some role in upper-middle and lower-middle-income countries; and (iv) financial crises have a negative and significant impact on GDP growth independently of the income level of the countries.     

An Institutional Perspective to Finance and Development as an Alternative to Financial Liberalisation

This paper argues that financial liberalisation as practiced recently worldwide engenders widespread financial crises precisely because of the weak foundations of its theoretical framework and poor empirical performance. Financial liberalisation is critically evaluated on both theoretical and empirical grounds, which suggests that an alternative is vitally necessary. Based on institutional theory,a new approach is proposed the focus of which is on ways to affect financial and banking transformation that is more consistent with economic development. We demonstrate how this theoretical approach can be applied in the real world, and indeed how the theoretical propositions we put forward in this contribution, very different from those of financial liberalisation, produce a more developmentally oriented set of policies for the countries that are prepared to pursue them.     

Financial and Capital Account Liberalization,Financial Development and Economic Development: A Review of Some Recent Contributions

Abstract

This article presents a review of some recent contributions on the relation between global finance and economic development in emerging economies. It first, stresses the growing consensus among economists on the financial instability that financial and capital account liberalization can possibly cause in emerging economies. It then outlines and compares two alternative strategies to tame such instability. The comparison is between the “good-institutions need-to-come-first” approach put forward by some mainstream economists, and the request for a deeper reform of the existing monetary system advocated by heterodox economists.     

Capital Openness and Financial Crises: A Financial Contagion Model with Multiple Equilibria

Abstract

This paper explores the effects of capital openness on financial crises and contagion. In the model, we analyze four channels of contagion involved in the process of financial crisis: monsoon effects, spillovers, self‐fulfilling expectations and new information. We empirically test the data from China, an economy with capital account controls, and find that the fundamentals of China (PRC) are now in a vulnerable area which yields multiple equilibria. Consequently, the Chinese economy is easily affected via the channels discussed in this paper. Finally we suggest that the capital account of China should be opened gradually.     

A test for the too-big-to-fail hypothesis for European banks during the financial crisis

Motivated by the theoretical prediction of the opportunistic behaviour of large banks that face expected public intervention, we test a full and a partial form of the too-big-to-fail (TBTF) hypothesis. The full form of the hypothesis implies the increase in the risk undertakings and profitability of banks that exceed a certain dimension; the partial form of the hypothesis implies only an augmented risk appetite of large banks compared to their smaller counterparts. The examined area is the European banking industry, whose behaviour is observed over the first wave of the present financial crisis (2007/09). The estimation of a quadratic fit that links change in a bank’s credit risk profile and profitability retention rates with a bank’s size suggests the existence of a partial form of the TBTF hypothesis. However, a more precise, local rolling windows estimation of the size sensitivities reveals that large banks – those whose liabilities exceed approximately 2% of the country of origin’s GDP (15% of our sample) – show an increase in credit risk profile and a superior capability of retaining higher ROA scores, vis-à-vis their smaller counterparts. With the caveats of our investigation, we interpret these results as evidence of a full form of the TBTF hypothesis.     

Intersectoral default contagion: A multivariate Poisson autoregression analysis

This paper analyzes credit rating default dependencies in a multisectoral framework. Using Mergent's FISD database, we study the default series in the U.S. over the last two decades, disaggregating defaults by industry-sector group. During this period, two main waves of default occurred: the implosion of the “dot-com” bubble and the global financial crisis. We estimate a Multivariate Autoregressive Conditional Poisson model according to the biweekly number of defaults that occurred in different sectors of the economy from 1996 to 2015. We discuss the contagion effect between sectors in two ways: the degree of transmission of the probability of default from one sector to another, i.e., the “infectivity” of the sector, and the degree of contagion of one sector from another, i.e., the “vulnerability” of the sector. Our results show differences between the sectors' relations during the first and second part of our sample. We add some exogenous variables to the analysis and evaluate their contribution to the goodness of fit.     

The determinants of cross‐border bank flows to emerging markets

This paper studies the determinants of cross‐border bank lending on a panel dataset comprising 17 advanced and 28 emerging market economies from 1993 to 2008. The empirical framework is based on a gravity model of financial flows. Our main findings are that the decrease in cross‐border lending in the 2007–2008 crisis was mostly due to global rather than country‐specific risk factors, and that central and eastern Europe was less affected by this decrease than other emerging market regions because of its stronger financial and monetary ties with creditor countries, and its relatively sound banking systems. These results are fairly robust to several different specifications, sub‐samples and econometric methodologies.     

QARMA-Beta-t-EGARCH versus ARMA-GARCH: an application to S&P 500

Statistical performance and out-of-sample forecast precision of ARMA-GARCH and QARMA-Beta-t-EGARCH are compared. We study daily returns on the Standard and Poor’s 500 (S&P 500) index and a random sample of 50 stocks from the S&P 500 for period May 2006 to July 2010. Competing models are estimated for periods before and during the US financial crisis of 2008. Out-of-sample point and density forecasts are performed for periods during and after the US financial crisis. The results provide evidence of the superior in-sample statistical and out-of-sample predictive performance of QARMA-Beta-t-EGARCH.     

A Model of Balance‐of‐Payments Crises due to External Shocks: Monetary vs. Fiscal Approaches

This paper develops a model for balance‐of‐payments (BOP) crises triggered by an external shock. Whether an external shock induces a BOP crisis depends crucially on the sequence of policy actions taken by the government's monetary and fiscal authorities. If the fiscal authority moves first and imposes an exogenous constraint on the monetary authority, an external shock can lead to a BOP crisis. However, if the monetary authority moves first and imposes an exogenous constraint on the fiscal authority, the same shock does not cause a BOP crisis.
