A Framework for Assessing Global Imbalances1

Since the mid‐1990s and prior to the financial crisis external balances of systemically important economies widened significantly. This paper takes a long‐run perspective and reviews the main determinants of widening global imbalances. To this aim, we first provide a set of newly derived statistical measures: while large external imbalances are not new in economic history, their persistence, their concentration on one economy (the United States) and the specific role of emerging market economies make the present episode rather unique. Second, we argue that the observed pattern of imbalances can be mostly understood as a result of various structural changes in the global economy, which have allowed a widening trend of external positions. Three main features set the most recent period apart from past episodes of growing external imbalances: (i) the emergence of new players, in particular emerging market economies such as China and India, which are quickly catching up with the advanced economies; (ii) an unprecedented wave of financial globalisation, with more integrated global financial markets and increasing opportunities for international portfolio diversification, also characterised by considerable asymmetries in the level of market completeness across countries; and (iii) the favourable global macroeconomic and financial environment, with record high global growth rates in recent years, low financial market volatility and easy global financing conditions over a long period of time, running until the outburst of the financial crisis during the summer of 2007. These structural changes that have been supplemented by cyclical or policy‐induced factors ultimately facilitated the sudden, disorderly unwinding of global imbalances that is reflected in the current financial crisis.

Is the Global Economy Headed for a Lost Decade? A European Perspective

In the 15 years leading up to the recent crisis, the world economy's exceptional performance was driven by globalisation, rapid, export-driven growth in emerging markets, debt-fuelled consumption in major advanced economies, and a benign financial and macroeconomic environment. These, however, sowed the seeds for the financial crisis by creating unsustainable imbalances and distortions. Obstacles to future growth are likely to be retrenchment in consumption, dampened investment, and unsustainable fiscal balances. Going forward, there must be a renewed commitment to medium-term, rule-based, policies for maintaining fiscal sustainability, price stability, and financial stability. The international imbalances between savings and consumption must also be addressed through a global reform agenda discussed in the paper. Even with reform, the challenges to growth will be daunting. Without reform, however, it is likely that the global economy will suffer a lost decade.     

The World Credit Crisis: Understanding It,and What to Do

The origin of the world credit crisis has four stages: (1) too much credit – an international perspective; (2) too much risk – reaction to low real interest rate; (3) the fatal flaw – the new complex financial instruments; and (4) the panic – bank lending dries up. The paper also discusses how the crisis spread around the world from the US, whether the high credit expansion was the fault of Alan Greenspan, whether China is to blame, and how this crisis related to the often expected crisis of global imbalances. Some implications for long‐term reform are discussed.     

The effects of the saving and banking glut on the U.S. economy

We use a quantitative equilibrium model with houses, collateralized debt and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one fourth and one third of the increase in U.S. house prices and household debt that preceded the financial crisis. The key to these findings is that the model generates the sustained low level of interest rates observed over that period.

The Determinants of Net Interest Margin in the Ghanaian Banking Industry

Abstract

This study investigates the determinants of net interest margin and the role of the financial crisis in explaining net interest margin (NIM) in the banking industry in Ghana. Further, we assess the sensitivity of our results to the measure of credit risk. We observe a sharp drop in NIM and an increase in bad debt growth during the 2007–2009 financial crisis in Ghana’s banking sector. Depending on the definition of credit risk, we observe marginal differences in the magnitude and significance of the determinants of NIM. Generally, NIM is explained by bank-specific, industry and macroeconomic factors. We find risk aversion, operating cost, inflation rate and previous year’s GDP growth to be robust drivers of NIM.     

Umbau der Finanzmärkte: Übermäßiges Vertrauen in Marktrationalität hält an

Governments on both sides of the Atlantic have reacted with a raft of new regulations to the US subprime mortgage crisis. The article argues that while these new rules actually touch many of the incentive and information problems which were instrumental in creating the crisis, they only address problems which can be analysed in the traditional neoclassical framework. Issues beyond this paradigm such as underlying market irrationality, bubbles, macroeconomic imbalances or the excessive complexity of the financial system have been left unattended. As these issues played an important role in the genesis of the crisis, new regulations will not suffice to stabilise the global financial system for long.     

The Changing Role of Financial Stress,Oil Price,and Gold Price in Financial Contagion among US and BRIC Markets

The objective of this paper is to explore the determining factors behind financial contagion between US and BRIC (Brazil, Russia, India, and China) equity markets. To this end, we investigate the effects of global macroeconomic factors on the time‐varying correlations among these markets obtained by asymmetric dynamic conditional correlation method. Utilizing quantile regression analysis, we examine the determinants of financial contagion at different levels of time‐varying correlations. The results of quantile regression analyses reveal that global financial crisis (GFC) (2008) leads to changes in the dependence structure between dynamic conditional correlations among equity markets and global macroeconomic factors, such as global financial stress, oil prices, and gold prices. Following the GFC, monetary, and fiscal policy changes in the BRIC markets and hence changing macroeconomic risks of these markets are conducive to these changes. Our findings also demonstrate the importance of cross‐market rebalancing channel for information transmission across US and BRIC markets.     

G20 Financial Officials Discuss Global Economy in Busan

In September 2009 the Group of Twenty （G20） took over the Group of Eight （G8） as a premier forum ,for international economic cooperation at the Pittsburgh Summit. The first achievement of the new forum, a “Framework for Strong, Sustainable, and Balanced Growth＂, would be tested and improved in the G20 meetings in June 2010. Considering the escalating debt crisis in the euro zone since this spring and calls for getting rid of the weaknesses of the financial regulatory system, the G20 assumed the responsibility to formulate global strategies to keep economic recovery on track and lead world economies and financial systems to get away from the mess in a more prudential and skillful way.     

Fiscal stimulus and its effects in the European Union

In the wake of the financial and economic crisis Keynesian macroeconomic management has once again come into the spotlight. The following article takes a critical look at the practice of expansionary fiscal policy in the EU’s old member states between 1980 and 2005 in order to answer the question whether fiscal stimulus can be a successful response to the current crisis in both the short and the long run.     

THE PARADOX OF DEBT AND MINSKY'S FINANCIAL INSTABILITY HYPOTHESIS

Some authors have claimed that the paradox of debt invalidates Minsky's theory of financial instability. Their theoretical frameworks are radically different from Minsky's in several aspects. Important Minskian elements, the role of margins of safety as a basis of financial decisions and the effects of asset prices on debt dynamics, among others, are absent in the critics' frameworks. We maintain that the thrust of the paradox of debt‐based criticism to Minsky's theory has been exaggerated and key insights of Minsky's theory of financial instability can be formalized in an alternative macroeconomic framework. We provide a stock‐flow consistent model of Minskian long waves.     

Transpacific Trade Imbalances: Causes and Cures

This paper explores the causes of the transpacific trade imbalances using an empirical global model. It also evaluates the impact of various policies to reduce these imbalances. We find the fundamental cause of trade imbalance since 1997 is changes in saving‐investment gaps, attributed to the surge of the US fiscal deficits and the decline of East Asia's private investment after the 1997 financial crisis. Our simulation results show that a revaluation of East Asia's exchange rates by 10 per cent (effectively a shift in monetary policy) cannot resolve the imbalances. We find East Asia's concerted efforts to stimulate aggregate demand can have significant impacts on trade balances globally, but the impact on the US trade balance is not large. US fiscal contraction is estimated to have large impacts on the US trade position overall and on the bilateral trade balances with East Asian economies. These results suggest that in order to improve the transpacific imbalance, macroeconomic adjustment will need to be made on both sides of the Pacific.     

Financial Repression — Ein neues Umfeld für die Finanzm?rkte?

High levels of debt caused by the financial crisis are forcing countries to take measures to reduce debt. Financial repression is a debt reduction opportunity based on measures imposed on the financial markets by governments which manifests itself primarily in lower real interest rates. Financial repression is regarded as another characteristic of a “new normality” in the global economy with low potential growth rates and low interest rates, high levels of public debt as a result of the financial crisis. The article describes this phenomenon and attempts to evaluate its empirical relevance.     

The ethical and policy implications of profiling ‘vulnerable’ customers

In the shadow of the global financial crisis, the issue of the marketing of credit has become an increasing concern in the past 12 months. Outstanding personal debt in the UK currently stands at £1479 billion and is rising by £1 million every 10.6 min. In Australia, there is currently $44.6 billion worth of outstanding credit card debt, and in the US, $2596 billion was owed on credit cards in 2008. At present, the banking sector utilizes sophisticated research methods to profile consumers, including those who might be considered financially vulnerable. However, the policy frameworks in most industrialized countries do not account for this form of target marketing when considering how to protect vulnerable groups. This paper is an initial attempt to examine the different methods by which profiling is conducted and the policy implications of this sophisticated form of segmentation and targeting. We argue that current consumer policies are inadequate in protecting vulnerable consumers from these marketing techniques, and recent recommendations from the Federal Reserve Bank of the United States, and the Australian Law Reform Commission to allow banks and lenders to ‘pre‐screen’ potential customers will exacerbate personal debt levels, rather than reducing them.     

Das europäische Verfahren zur Vermeidung und Korrektur von Leistungsbilanzungleichgewichten

The Macroeconomic Imbalance Procedure (MIP) is part of a institutional framework known as the so-called “sixpack“, which has come into effect on December 13th 2011 in response to the European financial and debt crisis. The crisis has shown that internal and external imbalances (in particular current account deficits) are strongly intertwined. The MIP should identify external imbalances at an early stage and thus compel countries to correct these imbalances to forestall potential crises. Methodological questions are discussed, which are to be resolved to ensure the effectiveness of the MIP.     

风险承担渠道：货币政策信贷传导渠道新探

近年来,＂风险承担渠道＂作为货币政策传导的一条新渠道,逐渐引起学界和业界的广泛关注。2008年爆发了全球性金融危机,反思其成因,＂过低的利率＂被一些学者认为是重要的诱因之一。长时期过于宽松的货币政策将引起投资者风险偏好的上升,导致金融不平衡的累积。风险承担渠道的研究表明,追求物价稳定的宽松货币政策对金融稳定产生了负面的影响。物价稳定与金融稳定双重目标的有效实现,需要货币政策与宏观审慎政策的协调配合。     

Strengthening the resilience of an economy

The financial crisis has affected the real economy in stages yet nevertheless at an unexpected rate and with all regions being affected simultaneously. It advanced almost independently of the regions’ exposure to the actual initial causes, among them the subprime crisis, innovative financial products, dubious microeconomic incentives, inefficient regulation and macroeconomic imbalances. The following analysis asks how national economic structures can be made more resilient to a shock (be it a financial crisis or another turbulence) and how economic policy can act in order to stabilise the economy before and after such a shock.
