Double Exponential Instability of Triangular Arbitrage Systems

If financial markets displayed the informational efficiency postulated in the efficient markets hypothesis (EMH), arbitrage operations would be self-extinguishing. The present paper considers arbitrage sequences in foreign exchange (FX) markets, in which trading platforms and information are fragmented. In Kozyakin et al. (2010) and Cross et al. (2012) it was shown that sequences of triangular arbitrage operations in FX markets containing 4 currencies and trader-arbitrageurs tend to display periodicity or grow exponentially rather than being self-extinguishing. This paper extends the analysis to 5 or higher-order currency worlds. The key findings are that in a 5-currency world arbitrage sequences may also follow an exponential law as well as display periodicity, but that in higher-order currency worlds a double exponential law may additionally apply. There is an "inheritance of instability" in the higher-order currency worlds. Profitable arbitrage operations are thus endemic rather that displaying the self-extinguishing properties implied by the EMH.Comment: 22 pages, 22 bibliography references, expanded Introduction and Conclusion, added bibliohraphy reference

Global debt dynamics: the elephant in the room

This introduction analyses the nature and characteristics of global debt dynamics in the post global financial crisis (GFC) period. First, we attempt to map the ways in which debt has been moving from sector to sector, and from one group of countries to another within the global economy. By capturing this inter-sectorial, inter-national, inter-regional movements of global debt we aspire to contribute to a more comprehensive understanding of global debt and its mode of operation. Second, we attempt to analyse what is wrong with global debt dynamics, i.e. we examine the broken link between what global debt was supposed to do and what it does. Here, we point to three interrelated dynamics: the accumulation of unproductive debt, growing inequalities of income and wealth, and the increase in privately-created, interest-bearing money. We conclude by discussing how each paper in this special issue contributes to the current state of the art on the analysis of global debt dynamics in emerging and developing economies

Global Capital Market Volatility and the Developing Countries: Lessons from the East Asian Crisis

Summary The emerging global economy is characterised by the virtually free movement of capital, while labour is still essentially confined to the nation state. The East Asian crisis has revealed the extent to which international financial ‘architecture’ does not yet correspond to this reality – let alone resolve its inconsistencies. The consequent public action problem is analysed in this article by first addressing the global causes of emerging market volatility and the failure of international financial institutions (such as the IMF) to contain it. The current attempt to extend multilateral bank regulation towards emerging markets is shown to suffer from severe limitations, as do proposals for mutual regulatory recognition and a global credit insurance system. The prospects for establishing a binding set of rules for global investment, with logical consequences for both multilateral capital taxation and international debt resolution, are improving, but remain problematic due to the ‘missing institutions’ required to create an orderly global capital market. The article concludes with an unexpected implication for the concept of citizenship itself

The new resilience of emerging and developing countries: systemic interlocking, currency swaps and geoeconomics

The vulnerability/resilience nexus that defined the interaction between advanced and developing economies in the post-WWII era is undergoing a fundamental transformation. Yet, most of the debate in the current literature is focusing on the structural constraints faced by the Emerging and Developing Countries (EDCs) and the lack of changes in the formal structures of global economic governance. This paper challenges this literature and its conclusions by focusing on the new conditions of systemic interlocking between advanced and emerging economies, and by analysing how large EDCs have built and are strengthening their economic resilience. We find that a significant redistribution of ‘policy space’ between advanced and emerging economies have taken place in the global economy. We also find that a number of seemingly technical currency swap agreements among EDCs have set in motion changes in the very structure of global trade and finance. These developments do not signify the end of EDCs’ vulnerability towards advanced economies. They signify however that the economic and geoeconomic implications of this vulnerability have changed in ways that constrain the options available to advanced economies and pose new challenges for the post-WWII economic order

Stabilising Capital Flows to Developing Countries

Summary The East Asian financial crisis is linked to volatile short?term capital flows. Restrictions on short?term inflows should be contemplated to cope with large surges in these capital flows. There is also a need to improve regulation of increasingly important institutional investors introducing risk?weighted regulation. The IMF could prepare for more rapid responses in the case of a crisis by maintaining ‘shadow programmes’ with countries before they are affected. It is also advisable to implement orderly workout procedures, involving private sector agents, for the case of insolvency. Further research is required on the behaviour of institutional investors, crisis contagion and changes in the international financial system

Financial crises and the attainment of the SDGs: an adjusted multidimensional poverty approach

This paper analyses the impact of financial crises on the Sustainable Development Goal of eradicating poverty. To do so, we develop an adjusted Multidimensional Poverty Framework (MPF) that includes 15 indicators that span across key poverty aspects related to income, basic needs, health, education and the environment. We then use an econometric model that allows us to examine the impact of financial crises on these indicators in 150 countries over the period 1980–2015. Our analysis produces new estimates on the impact of financial crises on poverty’s multiple social, economic and environmental aspects and equally important captures dynamic linkages between these aspects. Thus, we offer a better understanding of the potential impact of current debt dynamics on Multidimensional Poverty and demonstrate the need to move beyond the boundaries of SDG1, if we are to meet the target of eradicating poverty. Our results indicate that the current financial distress experienced by many low-income countries may reverse the progress that has been made hitherto in reducing poverty. We find that financial crises are associated with an approximately 10% increase of extreme poor in low-income countries. The impact is even stronger in some other poverty aspects. For instance, crises are associated with an average decrease of government spending in education by 17.72% in low-income countries. The dynamic linkages between most of the Multidimensional Poverty indicators, warn of a negative domino effect on a number of SDGs related to poverty, if there is a financial crisis shock. To pre-empt such a domino effect, the specific SDG target 17.4 on attaining long-term debt sustainability through coordinated policies plays a key role and requires urgent attention by the international community

Fund Management and Systemic Risk - Lessons from the Global Financial Crisis

Fund managers play an important role in increasing efficiency and stability in financial markets. But research also indicates that fund management in certain circumstances may contribute to the buildup of systemic risk and severity of financial crises. The global financial crisis provided a number of new experiences on the contribution of fund managers to systemic risk. In this article, we focus on these lessons from the crisis. We distinguish between three sources of systemic risk in the financial system that may arise from fund management: insufficient credit risk transfer to fund managers; runs on funds that cause sudden reductions in funding to banks and other financial entities; and contagion through business ties between fund managers and their sponsors. Our discussion relates to the current intense debate on the role the so-called shadow banking system played in the global financial crisis. Several regulatory initiatives have been launched or suggested to reduce the systemic risk arising from non-bank financial entities, and we briefly discuss the likely impact of these on the sources of systemic risk outlined in the article
