Post-crisis business investment in the euro area and the role of monetary policy

ABSTRACT

Business investment in the euro area strongly declined during the Global Financial Crisis and the Sovereign Debt Crisis. It has not yet rebounded to its pre-crisis trend despite the very expansionary monetary policy measures of the ECB. We analyse the sluggish recovery in business investment in the euro area and the role of monetary policy in three steps. We investigate the main factors that have impeded business investment since the Global Financial Crisis. We empirically analyse how business investment has developed compared to typical patterns during other financial crises. Based on these results, we then discuss how effective monetary policy has been in stimulating business investment since the Global Financial Crisis. We conclude that business investment in the euro area has developed broadly in line with typical post-crisis patterns. Monetary policy significantly contributed to stabilize business investment at the beginning of the crises. In the aftermath of the crises, however, there seems to be little scope for monetary policy to further stimulate investment.     

Does Purchasing Power Parity hold? New evidence from wild-bootstrapped nonlinear unit root tests in the presence of heteroskedasticity

In spite of the extensive research which has already been undertaken, the issue as to whether Purchasing Power Parity (PPP) empirically holds, continues to be strongly debated. Existing studies have been criticized for their reliance on unit root tests which are deemed to suffer from certain weaknesses such as the size distortion bias arising from heteroskedasticity. In this paper, we provide new evidence on PPP based on a new methodology that overcomes this problem. We use the widely accepted KSS (Kapetanios et al., 2003) non-linear unit root tests which we, however, wild bootstrapped. Through Monte Carlo simulation, we demonstrate that the wild-bootstrapped KSS is robust to heteroskedasticity-induced size distortion problem. We apply this method to test PPP across 61 countries over the period 1994 to 2012 — a period characterized by a number of crises such as the Asian Financial Crisis, Russian Crisis, dotcom crisis, Global Financial Crises, among others, and therefore, intense heteroskedasticity. Our results provide strong evidence against PPP. This paper contributes to both the international financial economics and econometrics literatures.     

How efficient is the banking system of Asia’s next economic dragon? Evidence from rolling DEA windows

Vietnam is now widely regarded as a rising economic star and the next economic dragon of Asia. Its banking system has played a key role in this stellar economic performance. Since 1990, Vietnam’s banking system has undergone significant changes which saw its composition transformed from being state banks only to now being both state as well as private banks, and has performed generally well in terms of growth, profitability and stability. But is it efficient? We conduct a dynamic analysis of the level and trend of the cost and profit efficiency of the Vietnamese banking sector over the period 1995 to 2011 taking into account the Asian and Global Financial crises. We use the Data Envelopment Analysis (DEA) Windows Analysis approach and adjust for bank size in calculating the average efficiency score of the banking system. Our empirical findings show that the cost and profit efficiency of the Vietnamese banking system averaged around 0.90 and 0.75, respectively, with the state banks being more efficient than the private banks and with efficiency experiencing an upward trend over the analysis period. Moreover, we find that the Global Financial Crisis (GFC) and Asian Financial Crisis (AFC) did not significantly affect the efficiency of the whole Vietnamese banking system.     

Portfolios in the Ibex 35 before and after the Global Financial Crisis

In this article, we present an analysis of the effectiveness of various portfolio optimization strategies applied to the stocks included in the Spanish Ibex 35 index, for a period of 14 years, from 2001 until 2014. The period under study includes episodes of volatility and instability in financial markets, incorporating the Global Financial Crisis and the European Sovereign Debt Crisis. This implies a challenge in portfolio optimization strategies since the methodologies are restricted to the assignment of positive weights. We have taken for asset allocation the daily returns with an estimation window equal to 1 year and we hold portfolio assets for another year. This article attempts to influence the discussion over whether the naive diversification proves to be an effective strategy as opposed to portfolio optimization models. For that, we evaluate the out-of-sample performance of 15 strategies for asset allocation in the Ibex 35, before and after of the Global Financial Crisis. Our results suggest that a large number of strategies outperform to the 1/N rule and to the Ibex 35 index in terms of return, Sharpe ratio and lower VaR and CVaR. The mean-variance portfolio of Markowitz with short-sale constraints is the only strategy that renders a Sharpe ratio statistically different from Ibex 35 index in the 2001–2007 and 2008–2014 time periods.     

Causes and hazards of the euro area sovereign debt crisis: Pure and fundamentals-based contagion

This paper tries to contribute to the understanding of sovereign debt crises' pattern by empirically investigating the determinants of the recent euro area crisis to assess if its transmission was due to “pure” or “fundamentals-based” contagion. Using sovereign bond yield spreads with respect to Germany for a sample of ten central and peripheral countries from January 1999 to December 2012, we firstly examine the dynamic evolution of Granger-causality within the 90 pairs of yield spreads in our sample to detect episodes of contagion (associated with episodes of significant intensification in causality). Secondly, we make use of a logit model to explore whether there is evidence of “pure contagion” or “fundamentals-based contagion”, by trying to determine which factors might have been behind the detected contagion episodes. Our results suggest that contagion episodes are concentrated just after the inception of the EMU and matching the Global Financial Crisis, yielding more accurate and sensible indicators than those obtained from DCC-GARCH models used in prior studies. Indeed, they preceded the outburst of the Global Financial Crisis (causality intensification is detected from March 2008), and reached a peak during January–May 2011. Furthermore, they underline the coexistence of “pure” and “fundamentals-based contagion” during the recent European debt crisis.

Semi-peripheral Financialisation and Social Reproduction: The Case of Portugal

Portugal, a semi-peripheral country within the world economy, has followed financialisation processes similar to and distinct from those of core countries. This article reflects on the factors that have shaped social reproduction in Portugal by examining the differentiated ways through which finance has interacted with the provision of housing, pensions and water and their variegated impacts. Based on these three case studies, the article discusses the constraints on, and pressures for, continued expansion of finance in the aftermath of the Global Financial Crisis. It underlines the subordinated and uneven nature of Portuguese semi-peripheral financialisation, the role of European integration in its unfolding, and concludes that the promotion of the interests of finance located in major advanced capitalist countries, and of the national and international institutions under their influence, has resulted in growing social and spatial inequalities.     

The varying shadow of China's banking system

The rapid rise of shadow banking activities in China since 2009 has attracted a great deal of attention in both academia and policy circles. Most existing studies and commentary on China's shadow banking have treated it as a recent phenomenon that appeared after the Global Financial Crisis and China's response to it. In this paper, I argue that shadow banking is not a new phenomenon; it has always been a part of China's financial system since the 1980s, and arose from the need to get around various lending restrictions imposed by the central government on banks. I also emphasize that there are two types of shadow banking activities, those initiated by banks and those initiated by local governments or state-owned enterprises. I provide evidence suggesting that the shadow banking activities initiated by banks prior to 1996 helped directing credits to the more productive non-state sector and were efficiency enhancing. In recent years, however, I find that the shadow banking loans have a positive effect on real estate investments only, and their effects on investments by private firms outside the real estate sector have been negative.     

Calculating the Efficient Frontier for the Portuguese Stock Market

The paper investigates the efficient frontier and capital market line for the Portuguese stock market before and after the Global Financial Crisis. The efficient frontier and capital market line shift to positions that offer investors better opportunities as we move from 2000‐2008 to 2009–2015.     

A theory of the non-neutrality of money with banking frictions and bank recapitalization

The unconventional monetary policy actions of the Federal Reserve during the recent Global Financial Crisis often involve implicit subsidies to banks. This paper offers a theory of the non-neutrality of money associated with capital injection into banks via nominal transfers, in an environment where banking frictions are present in the sense that there exists an agency problem between banks and their private-sector creditors. The analysis is conducted within a general equilibrium setting with two-sided financial contracting. We first show that even with perfect nominal flexibility, the recapitalization policy has real effects on the economy. We then introduce banking riskiness shocks and study optimal policy responses to such shocks.     

Regulating Synthetic Securitisation Following the Global Financial Crisis

This article explores whether proposed changes to the regulation of synthetic securitisation in Australia are sufficient in light of the Global Financial Crisis. Synthetic securitisation is specifically chosen as an object of study, given the relative ease with which it can be over‐used. The article examines several theoretical problems with securitisation, which entice corporations into excessively risky behaviour. Contrary to popular belief, it is established that agency issues are not a serious problem with securitisation. Instead, managerial behavioural biases are shown to be most problematic. The article recommends stricter capital adequacy relief requirements, which would provide a disincentive for excessive risk‐taking by potentially over‐confident managers.     

The predictive ability of a risk-adjusted yield spread for economic activity in Europe

This paper examines whether the pricing of risk is important for macroeconomic activity at the country level. We design a risk-adjusted yield spread and test its predictive content for economic activity on the periphery and the centre of Europe over the 1990–2012 period. This risk-adjusted bond yield spread is defined in a cross-country context and referred to as the GZ-type spread. Increases in the yield on corporate bonds issued in the countries on the periphery relative to the riskless yield (calculated using German zero-coupon term structure data) reflect increases in the risk premium that the financial market imposes on borrowers. The risk premium rises in all countries during European-wide recessions of the recent past, particularly those associated with the Global Financial and the Sovereign Debt Crisis. Our findings indicate further that this GZ-type spread acts as a reliable signal for imminent and near-term economic activity in countries where financial markets were shaken to their foundations during the Crisis period. For Germany, the GZ-spread has predictive content for industrial production but not for the unemployment rate. For GDP its predictive ability is confined to the EMU period.     

Predicting long-run risk factors of stock returns: Evidence from Australia

This study utilises the stock market data provided by the Australian Equity Database to analyse the long-run relationship between Australian stock returns and key macroeconomic variables over the period 1926–2017. To measure the diverse risk factors in the stock market, we examine the possible determinants in four main categories: real, financial, domestic and international. Our results reveal that historical stock returns are strongly connected to financial and international factors as compared to real and domestic factors. Both the 1973–1974 OPEC Oil Price Crisis and 2007–2008 Global Financial Crisis had dampening effects on stock returns. There is a positive association between the US and Australian stock markets in the long-run. These findings on stock market dynamics and their linkages with domestic and international macroeconomic policy changes in the long-run have important implications for traders and practitioners.     

Are all financial crises created equal? Wholesale funding and two financial crises

We use financial information on banks from Asia, Europe, North America and Oceania to examine the role of wholesale funding on the transmission of financial crises to bank lending, as well as to study the response of financial institutions in different regions during the crises. We consider the role of wholesale funding during the Global Financial Crisis (GFC) and Asian Financial Crisis (AFC). Our results suggest that during the GFC, wholesale funding dependence had a negative effect on loans growth across regions, but with substantial regional heterogeneity. The growth of loans from financial institutions in Asia and Europe was consistently sensitive to wholesale funding dependence. Although wholesale funding did not play a significant role in the transmission mechanism of the AFC, a subsample of financial institutions in Asia, who depended more heavily on wholesale funding, experienced a faster loan growth and may have been able to better withstand the crisis.     

Improved output gaps with financial cycle information? An application to G7 countries’ new Keynesian Phillips curves

In search for more robust cyclical imbalance indicators, recent research has highlighted the interactions between business and financial cycles. Output gap formulations increasingly take imbalances of the financial cycle into account, postulating finance-neutral output gaps (FNGAPs). To test their increased explanatory power in econometric models, we compare FNGAPs to univariate output gaps in their ability to explain inflation dynamics in hybrid new Keynesian Phillips curves. Results indicate FNGAPs to exercise (dis)inflationary pressure, but not to outperform traditional output gaps. Nonetheless, they have become increasingly significant in the course of the 2007/08 Global Financial Crisis.     

代工制造、金融危机与东部地区产业升级

金融危机引发国际市场需求锐减,将东部地区以代工制造为主导的产业置于前所未有的困境之中。本文认为,其根本原因在于出口导向型代工产业自身的固有缺陷,即严重依附于跨国公司和国际采购商的生产者驱动和购买者驱动,金融危机只是一个放大器。出口导向型代工产业由于内在升级动力机制无法有效建立,造成产业内源性升级缓慢,但金融危机却在客观上为产业外源性升级提供了契机。金融危机背景下东部地区产业升级的方向在于:一是沿着产业链的上游进行技术破坏,从代工供给终端摆脱对生产者驱动的依附;二是沿着产业链的下游进行市场破坏,从代工需求终端摆脱对购买者驱动的依附。     

Using Psychology to Improve Economic Policy

In this Australian Treasury seminar, I discuss the contributions that psychology could make to public policy formation via a new field: public policy psychology. Behavioural economics provides a precedent for my new field of public policy psychology. Unlike economics, psychology provides a solid scientific model of how individuals make decisions. I discuss shortcomings of economics in policy formation: model blindness, the focus on evidence supporting theories, the focus on markets, plus the importance of elements left out of conventional economic models (for example, irrational decision‐makers). I end by discussing two Treasury case studies: the mining tax and government responses to the Global Financial Crisis.     

On the problem of scale: Hayek, Kohr, Jacobs and the reinvention of the political state

There is no shortage of crises in the ecological (e.g. climate change), economic (e.g. the Global Financial Crisis), and socio-political spheres (e.g. the Arab Spring). While such crises are not new to the human saga, both the magnitude and frequency of these crises seem to be intensifying. The usual prognosis follows the public/private dichotomy, suggesting more or less government intervention (and the closely related variants of more integration and regime change). However, there are ‘islands’ of alternative analyses where crises result from scale distortion (organisational structures of states, markets and firms that are too large or too small) and scale entanglement (strong rather than weak ties between different scales such as the local, national and global). This paper attempts to synthesise this scale problematisation into one coherent school of thought. To this end, we introduce the complexity ansatz, which links complexity to symmetry (breaking), scale and collapse. To illustrate, the paper traces this ansatz in the writings of Friedrich Hayek, Léopold Kohr and Jane Jacobs (HKJ). The thesis is that the moribund nation state needs to be relegated to a subsidiary role to evade collapse. Loosely coupled (fiscally and monetarily) autonomous city-regions should be the ‘eyes’ of socio-economic action.     

Is Australia One Recession Away from a Disability Blowout? Lessons from Other Organisation for Economic Co‐operation and Development Countries

A blowout in disability‐based cash transfer programmes resulted in fundamental reforms over the last decade in several Organisation for Economic Co‐operation and Development countries. Similar reforms are being proposed in the United States in the wake of its disability programme growth following the Global Financial Crisis. We compare trends in US and Australian disability receipt with those of the Netherlands and Sweden and argue that Australia's current Disability Support Pension programme is vulnerable to the same forces that caused unsustainable programme growth in these countries. Absent fundamental reforms focused on return to work over benefit receipt means that Australia could be one recession away from disability benefit blowout.     

The transmission mechanism of Malaysian monetary policy: a time-varying vector autoregression approach

The aim of this paper is to determine whether the propagation and transmission mechanism of Malaysian monetary policy differed during the Asian Financial Crisis of 1997/1998 and the Global Financial Crisis of 2007/2008. The methodology employs a time-varying vector autoregression framework. The primary result is that despite having no evidence of time-variation within the propagation mechanism of Malaysian monetary policy the average contribution of a monetary policy shock to the variability of each macroeconomic variable: real GDP, inflation and the nominal effective exchange rate, differs between the two crises. This finding suggests that despite the propagation mechanism being relatively constant, Malaysia’s monetary policy transmission mechanism evolves over time. We believe that the main mechanism driving this evolution is the time-variation in the variance–covariance matrix of the shocks of the model, not the coefficients. We also find some evidence that the implementation of capital controls reduced the influenceability of monetary policy on the Malaysian economy.
