Eurozone crisis and BRIICKS stock markets: Contagion or market interdependence?

This paper examines the financial contagion in an emerging market setting by investigating the contagion effects of GIPSI (Greece, Ireland, Portugal, Spain and Italy), USA, UK and Japan markets on BRIICKS (Brazil, Russia, India, Indonesia, China, South Korea and South Africa) stock markets. During Euro-zone crisis period (October 19, 2009–January 31, 2012), the empirical results indicate that among GIPSI countries, Ireland, Italy and Spain appear to be most contagious for BRIICKS markets compared to Greece. The study reports that Brazil, India, Russia, China and South Africa are strongly hit by the contagion shock during the Eurozone crisis period. However, Indonesia and South Korea report only interdependence and not contagion. From policy perspective, the findings provide useful implications for possible decoupling strategies to insulate the economy from contagious effects. For multilateral organizations like International Monetary Fund (IMF) and World Bank, the study will provide an important direction in undertaking coordinated rescue measures for the vulnerable as well as contagious countries.     

A core–periphery framework in stock markets of the euro zone

The introduction of the euro was expected to have an effect not only on real convergence of economies but also on stock markets. This research compares the dynamics and synchronization of stock market regimes in European markets before and after the euro launch. Countries of the euro zone are found to have different dynamics with regard to switching between bull and bear markets, but the differences become less pronounced after the introduction of the single currency, increasing the overall level of stock market synchronization. Nevertheless, Austria and Portugal reduced the level of regime synchronization with other stock markets. The results delineate a framework of core–periphery stock markets, i.e., a large group of stock markets that share the same market regime, with some others on the periphery characterized by distinctive behavior.     

What can we tell about monetary policy synchronization and interdependence over the 2007–2009 global financial crisis?

We investigate the synchronization and nonlinear adjustment dynamics of short-term interest rates for France, the UK and the US using the bi-directional feedback measures proposed by Geweke (1982) and appropriate smooth transition error-correction models (STECM). We find evidence to support the increasing synchronization of these rates over the period 2005–2009 as well as of their lead–lag causal interactions. Moreover, short-term interest rates converge towards a common long-run equilibrium in a nonlinear manner and their time dynamics exhibit regime-switching behavior. As far as the underlying types of monetary policies conducted by the world’s leading central banks are concerned, our empirical evidence thus reveals strong interdependence, but only some degree of synchronization.     

Are Islamic stock markets efficient? A time-series analysis

This article investigates the weak-form informational efficient hypothesis for three major Islamic stock markets (world, emerging and developed). Unlike previous studies, we applied different parametric and nonparametric tests to investigate efficiency in the short and long horizons. Using recent data over the period May 2002–June 2012, we developed a time-series analysis of Islamic stock price dynamics in the context of the recent global financial crisis (2008–2009). Our analysis offers two interesting results. First, emerging Islamic stock markets seem to be less efficient than developed Islamic markets, suggesting interesting investment opportunities and diversification benefits from this region in both the short run and the long run. Second, nonrejection of the cointegration hypothesis for developed Islamic markets and the global conventional stock market point to efficiency for the former in the long term, even if it is inefficient in the short term. This finding has at least two economic and political implications: (i) investors who seek moderate risk would do well to opt for Islamic funds in developed countries, particularly as they share the same tendency and provide similar expected returns in the long term as conventional funds, (ii) Islamic financial systems can offer a useful model that can help to reform and remodel conventional financial institutions.     

Has the structural break slowed down growth rates of stock markets?

In this paper, we use the common structural break test suggested by Bai et al. (1998) to test for a common structural break in the stock prices of the US, the UK, and Japan. On the basis of the structural break, we divide each country's stock price series into sub-samples and investigate whether or not the structural break had slowed down the growth of stock markets. Our main findings are that when stock markets are modelled in a trivariate sense the common structural break turns out to be 1990:02, with the confidence interval including several episodes, such as the asset price bubble when housing prices and stock prices in Japan reached a peak in 1988/1989, the early 1990s recession in the UK, the business cycle peak of July 1990, the August 1990 Iraqi invasion of Kuwait and the March 1991 business cycle trough. Annual average growth rates suggest that the structural break has slowed down the growth rate of the US, the UK and Japanese stock markets.     

Does monetary integration lead to income convergence in Africa? a study of the CFA monetary area

Portuguese Economic Journal - The CFA franc area is one of the oldest currency unions, but it has come under intense criticism recently for failing to promote economic growth and income convergence...     

The role of Chinese stock market in global stock markets: A safe haven or a hedge?

The contribution of the study is threefold. First, the paper proposes a new empirically testable definition for a safe haven and a hedge from the viewpoint of extreme and regular dependences measured by a modern statistical tool of copulas. Second, this paper investigates the extreme and regular dependences between the Chinese and the G7 stock markets, using a mixture copula specification, and the results reveal that the Chinese stock market has been not only a hedge but also a safe haven for the G7 stock markets all these years. Finally, this study suggests that the Chinese stock market is the target market for global stock fund managers and international investors, who are seeking a hedge or a safe haven for their portfolios, under turbulence.     

What are the effects of fiscal policy on asset markets?

We investigate the link between fiscal policy shocks and asset markets. Our results show that spending shocks have: a positive and persistent effect on GDP in the U.S. and in the U.K., while for Germany and Italy, such impact is temporary; a positive and persistent effect on housing prices; a negative effect on stock prices; and mixed effects on the price level. A VAR counter-factual exercise suggests that fiscal shocks play a minor role in the asset markets of the U.S. and Germany, and substantially increase the variability of housing and stock prices in the U.K., while government revenue shocks have increased volatility in Italy.     

What can biology tell us about transaction balances?

The total cash issuance of a central bank consists of domestic transaction and hoarding balances as well as foreign demand. The different shares are not known exactly. The introduction of the new Europa series of banknotes in the euro area offers the opportunity to calculate transaction balances with the help of a biometric method. Our results indicate that transaction balances are very low.     

Does the introduction of stock exchange markets boost economic growth in African countries?

We assess whether the introduction of private equity capital markets affects economic growth in African countries. We address this issue by focussing on stock exchange markets as the predominant type of new equity markets, using a Diff-in-Diff regression method. The analysis uses a panel data set from 48 Sub-Saharan countries over the time range of 1970–2018. 23 countries are part of the “treated” group – which introduced international stock exchanges – and 25 “untreated” countries serve as the control group. Our results show that when compared with the time period prior to the introduction of stock exchange markets, GDP per capita rises by the amount of 532 US$ (around 40% of the Sub-Saharan average) after the introduction of equity capital markets in the treated countries. Over the ten years post introduction, the effect is hump-shaped, with effects becoming statistically significant from the first year after implementation, with a peak in the 5th year, and it then becomes statistically insignificant from then onwards.     

A wavelet analysis of capital markets’ integration in Latin America

The continuous wavelet transform analysis may provide a rich and flexible framework for the analysis of time series which exhibit less stable statistical properties, such as the ones describing the dynamic trajectory of capital markets. In contrast to the Fourier analysis, wavelet transform preserves information on both time and frequency. We provide a summary of the most important features of this framework. By involving the concept of coherence as well as its partial and multiple forms, we analyse the connections between Santiago Stock Exchange, Mexican Stock Exchange and BM&FBOVESPA São Paulo Stock Exchange, for a time span which covers the 23 September 2003–12 March 2014 period. We highlight the existence of several significant forces of regional integration and of a short- to medium-run synchronization process between these markets. We conclude that deeper structural and institutional reforms are required in order to enhance the sustainable development and more profound integration of these markets.     

Dynamic pricing and asymmetries in retail gasoline markets: What can they tell us about price stickiness?

Theoretical explanations for price stickiness used in businesses cycle models are diverse (e.g., information processing delays, rational inattention and fair pricing), with each theory resulting in a different implication for inflation dynamics. Using an autoregressive conditional binomial model and a data set consisting of daily observations of price and cost for 15 Philadelphia retail gasoline stations, we test which of these theories is most consistent with the observed pattern of price adjustment. Our findings of time dependence, asymmetry and the role of cost volatility are consistent with a combination of fairness considerations and rational inattention by producers.     

Have minutes helped markets to predict the MPC's monetary policy decisions?

This paper examines whether the minutes of the Bank of England's Monetary Policy Committee (MPC) have provided markets with additional information about the future course of monetary policy. The paper conducts an econometric approach based on an Ordered Probit model explaining future policy rate changes (sample 1998 to 2014), and the Vuong test for model selection, which helps to identify changes in the market assessment around the release of MPC minutes. Our results suggest that the Bank of England's published minutes of the MPC's deliberations have indeed helped markets in forming their expectations on future monetary policy decisions.     

What can Islamic financing tell us about macro-prudential policies?

Macro-prudential policies are theoretically effective at mitigating a debt deflation crisis by forcing individuals to internalize their impact on aggregate prices reducing systemic risk caused by pecuniary externalities. To better understand the potential effectiveness of a macro-prudential time varying tax/subsidy on debt/dividends, we empirically estimate the impact of an Islamic financing presence on financial crises. Adherence to Islamic financing principles for a nontrivial portion of a country’s population has similar impacts to a macro-prudential policy in that these limited asset holders are likely to hold less debt or use debt-like instruments rather than conventional debt, driving down their marginal rate of substitution and the price of equity in equilibrium. To empirically estimate the effects of this policy, we interact an Islamic financing variable with debt in an otherwise standard model of financial crises. The results show that this macro-prudential-like policy decreases the likelihood of a banking crisis by 50%. The contribution of the article is twofold. First, we show that an Islamic finance presence encourages precautionary savings like a macro-prudential policy. Second, using an Islamic finance presence to capture macro-prudential potential effects, we find empirically that the likelihood of banking crises are cut roughly by half when such policies are in effect.     

Does crude oil move stock markets in Europe? A sector investigation

The aim of this article is to investigate the responses of European sector stock markets to oil price changes. We use linear and asymmetric models and study the association of oil and stock prices. Our findings suggest that the strength of this association varies greatly across sectors. Moreover, for some sectors we find strong evidence of asymmetry in the reaction of stock returns to changes in the price of oil.     

What does high-dimensional factor analysis tell us about risk factors in the Australian stock market?

Estimates of the cost of equity are often sensitive to the specification of the linear factor model used in their construction. In this article, we use techniques developed for high-dimensional factor models to consider the identity of systematic risk factors in the Australian equities market. Our results support the use of neither the Capital Asset Pricing Model (CAPM) nor the Fama and French model, although they provide an explanation for the empirical performance of these models. Many other model specifications are also rejected. We find that a single-factor model with an equal-weighted market index is the best model for estimating the cost of equity in the Australian context.     

What can we learn from the distribution of trade patterns?

This paper proposes an empirical framework for analyzing the dynamics of trade specialization, using a symmetric transformation of the standard Balassa (Manch Sch Econ Soc Stud 33(2):99–123, 1965) index and the conditional density estimation methods suggested by Hyndman et al. (J Comput Graph Stat 5(4):315–336, 1996). The framework is implemented using data on the cross-sector export and import specialization of the four initial EU Cohesion countries over the last 40 years. We discuss the importance of studying both the distribution’s external shape and the intra-distribution dynamics and why it is interesting to include imports in the analysis. We find a reduction of the overall degree of export specialization in Portugal, Greece and Spain. Conversely, Ireland has the strongest export specialization and there is evidence of an increase over time. The export intra-distribution dynamics reveal persistence of the specialization status in the four countries, especially for high values of the index. In all countries, the degree of specialization is higher for exports than for imports and intra-distribution dynamics reveal more mobility of import specialization than that of exports.     

Can consumption-based asset pricing models using monetary conditioning variables explain the cross-section of German stock returns?

In this article, we analyse whether simple Consumption-based Capital Asset Pricing Models (CCAPMs) using monetary conditioning information (growth of the money aggregates M1, M2 and M3) can explain the cross-section of German size, book-to-market and industry portfolio returns. Our results show that models having stochastic discount factor parameters that vary with money aggregates can reduce the pricing errors of models with constant parameters. However, a large proportion of the cross-sectional variation remains unexplained.
