Nonlinearities in emerging stock markets: evidence from Europe's two largest emerging markets

Recent developments in time series analysis allow proper modelling of nonlinearities in economic and financial variables. A growing body of research was dedicated to investigation of potential nonlinearities in conditional mean of many economic and financial variables, mainly concentrating in developed economies. However, nonlinearities in financial variables in developing economies have not been fully examined yet. In this article we investigate potential nonlinearity and cyclical behaviour of stock returns in Europe's two largest emerging stock markets, mainly in the Greek and Turkish stock markets. Specifically, we use STAR family models, which allow to model nonlinearities in the conditional mean, for modelling monthly returns on stock exchange indices of the Athens Stock Exchange and Istanbul Stock Exchange. Although we find no nonlinearity in conditional variance, we do find strong evidence in favour of nonlinear adjustment of stock returns. It is found that allowing for nonlinearity in conditional mean results in a superior model and provides good out-of-sample forecasts, which contradicts to efficient market hypothesis.     

Institutional arrangements and price rebalancing: empirical evidence from the United States and Europe

This paper explores the rebalancing of prices for voice service in the United States (US) and the European Union (EU) from conceptual and empirical perspectives. We determine the overall cost and structure of a standardized basket of residential and business services. Our data indicate that during the 1994–2000 period the degree of rate rebalancing was significantly higher in the EU than in the US. While the developments at the level of EU Member States are more heterogeneous and the process of rate rebalancing is not completed, these findings correspond to the predictions derived from our comparative institutional analysis.     

Co-movement and spillovers: empirical evidence from BRIC equity markets

A higher degree of co-movement and spillover effects among different asset classes undermine portfolio diversification benefits. In this regard, the present study attempts to capture dynamic co-movement and return-volatility spillover effects among the most promising emerging equity markets, i.e. Brazil, Russia, India and China in a multivariate framework by employing VAR-ABEKK and VAR-DCC-AGARCH (1,1) models. To further comprehend the behaviour of the correlation coefficients during the global financial crisis period (2007–2009), heat map and Markov regime switching model (two regimes with a switch at ‘mean’ level only) have been used. The results report that the BRIC equity markets do not share a common stochastic trend in the long run. There is strong evidence of market shocks to volatility, volatility to volatility and negative shocks to volatility spillover effects among the BRIC markets. Overall, the BRIC markets are partially integrated with each other, thereby making them stronger investment candidates.     

Capital structure and value of reported earnings: evidence from an emerging market

This article documents a nonlinear impact of capital structure on the value of reported earnings in India during the period between 2009 and 2015. Our results show that earnings reported by firms with moderate level of debt are more valuable than earnings reported by firms with low or high level of debt. Our results are robust across various proxies of capital structure and across various sub-samples. This article argues that moderate level of debt is associated with low-agency problems, while low and high level of debt is synonymous to high-agency problems. Differences in agency problems result in reported earnings that have very different levels of relevance.     

The risk-return relations: evidence from the Korean and Taiwan stock markets

This article examines the risk-return relations conditional on up and down market periods in the Korean and Taiwan stock markets. Based on statistical tests adjusted for the effects of heteroskedasticity and autocorrelation of the residuals, beta is found positively (negatively) related to realized returns in up (down) markets. However, the results are sensitive to portfolio aggregation methods. Its role as a risk measure vanishes in down markets for the two-way (beta-size and size-beta) sorted portfolios. Unsystematic risk is significantly and positively priced only in up markets and mainly for beta-sorted portfolios while total risk is correctly priced except in Taiwan during down markets. Moreover, the impact of skewness and kurtosis on realized returns is not only sensitive to portfolio aggregation methods but also different across stock markets. They are found to be more relevant risk characteristics in the Korean than in the Taiwan stock market.     

The relationship between developed equity markets and the Pacific Basin's emerging equity markets

Using a trivariate vector autoregression (VAR) model with a proper control for heteroscedasticity, this paper investigates the relationships between the two largest equity markets in the world—the U.S. and Japan—and the four Asian emerging equity markets: Hong Kong, Korea, Singapore, and Taiwan. Evidence indicates that the links between the developed markets and the Asian emerging markets (AEMs) began to increase after the stock market crash in October 1987, and have significantly intensified since the outbreak of the Asian financial crisis in July 1997.     

Exogenous shocks,dynamic correlations,and portfolio risk management for the Asian emerging and other global developed and emerging stock markets

ABSTRACT

This study examines the potential influence of exogenous shocks on time-varying correlations and portfolio strategies between the Asian emerging and other global stock markets including developed and other emerging markets. Using the ARMA-cDCC-FIEGARCH model with and without exogenous shocks, our results highlight the usefulness of including other global stock assets in the traditional portfolio for Asian emerging market investors. However, investors have limited opportunities to diversify their assets during the global financial crisis. Moreover, the shocks from the U.S. stock market have a greater influence on global stock markets compared to that from U.S. economic policy. Fortunately, the model with exogenous shocks improves its accuracy, which plays the same role of controlling structural breaks in the model. More importantly, incorporating exogenous shocks in our model also provides better value-at-risk performance results and hedging effectiveness. These results have several important implications for investors, researchers, and policymakers.     

Market segmentation and information values of earnings announcements: Some empirical evidence from an event study on the Chinese stock market

This paper investigates the trading activities of two distinct classes of shareholders, namely, the Chinese domestic investors and the foreign investors in the segmented Chinese A- and B-share markets, respectively. We conduct an event study on the annual earnings announcements based on two different accounting standards: International accounting standards (IAS) and PRC generally accepted accounting principles (PRC GAAP). The earnings announcements based on IAS and PRC GAAP are value relevant. The investors in the B-share market react to both the IAS and PRC GAAP earnings announcements, while the investors in the A-share market pay more attention to the PRC GAAP earnings reports. In the B-share market, positive abnormal returns are associated with positive earnings surprise and negative abnormal returns go with negative earnings surprise. We find preevent abnormal trading volumes without significant price changes for the A shares, which may be due to existing information in the A-share market prior to earnings announcements. The postevent abnormal trading volumes last for a longer period in the A-share market than in the B-share market.     

Conditional risk and return in Asian emerging markets: evidence from the banking sector

Previous studies reach no consensus on the relationship between risk and return using data from one market. This study argues that the market factor should be noticed in assessing the risk-return relationship in a partially integrated emerging market. The analysis aims to provide new insight into the nature of the risk-return relationship by a conditional factor GARCH-M framework that controls for time-series effects, to investigate the banking sector in five Asian emerging markets of China, Hong Kong, Indonesia, Malaysia and Taiwan during the period 1995 to 2004. Finally, the study provides evidence on these relations before and after the Asian financial crisis of 1997. The results are generally consistent across the markets and with expectations, and have implications for empirical assessments of the risk-return relationship and diversification.     

Computerization and immigration: Theory and evidence from the United States

Recent technological changes have been characterized as “routine-substituting” because they reduce demand for routine tasks and increase demand for analytical and service tasks. Little is known about how these changes have impacted immigration, or task specialization between immigrants and native-born individuals. In this paper, we show that such technological progress has attracted immigrants who increasingly specialize in manual-service occupations. We also suggest that openness to immigration attenuated the job and wage polarization faced by native-born from technological changes. We explain these facts with a model of technological progress and endogenous immigration. Simulations show that unskilled immigration attenuates the drop in routine employment proceeding from technological change, enhances skill upgrading for native-born and raises economy-wide productivity and welfare.     

Credit channel and flight to quality in emerging markets: evidence from Chile

Empirical evidence of the credit channel of monetary policy often relies on the observance of flight to quality during monetary tightening. The identification assumption is that the typically smaller firms facing financing constraints, are disproportionally affected by the stance of monetary policy. I argue that when credit constrains are widespread, as may be the case in Emerging Markets, flight to quality should not be expected during monetary contractions. Indeed, in my model, among constrained firms, those with tighter financing constraints are less responsive to monetary conditions. I find evidence supporting my model in a sample of firms from the Emerging Market of Chile.     

Environmental disclosure and stock market liquidity: evidence from Arab MENA emerging markets

The objective of this study is to examine the impact of environmental disclosure levels on the stock market liquidity of Arab Middle Eastern and North African (MENA) companies. For that, a self-constructed disclosure index was applied to the annual reports for the years 2010, 2011 and 2012 and the bid-ask spread was used as a proxy for stock market liquidity. Results indicate that levels of environmental disclosure in MENA companies are quite low. In addition, using a sample of 276 firm-year observations, multivariate analysis shows that the higher the level of environmental disclosure provided in the annual reports, the lower the spread between the market bid and ask prices, thereby indicating an increase in stock market liquidity.     

Social benefit expenditures and stagflation: evidence from the United States

Stagflation refers to the terrible economic malaise associated with declining growth, hyperinflation and high unemployment. Unlike previous cost-push explanations such as an overheated labour market and oil prices, this article suggests that social benefit expenditures are a potential cause of stagflation. We investigate the impact of social benefit expenditures on stagflation in the U.S. over the 1950–2014 period by employing an autoregressive distributed lag (ARDL) bounds testing approach to cointegration, which was developed by Pesaran, Shin, and Smith. The influence of social benefit expenditures on economic growth and inflation and unemployment rates is estimated. The empirical results from the U.S. suggest that economic growth responds negatively to social benefit expenditures, while inflation and unemployment rates are both positively associated with social benefit expenditures. Thus, government-led rigid welfare could contribute to stagflation in the U.S. Instead of increasing people’s happiness, the over-burdened welfare system could push people into economic malaise. This stagflation risk shouldn’t be ignored. These results are important for U.S. policymakers and can inform other governments characterized by high levels of well-being.     

The earnings of Mexican immigrants in the United States

"This paper documents the trends in the earnings of Mexican immigrants during the 1970-1990 period. The empirical evidence indicates that there has been a decline in the relative wage of successive Mexican immigrant waves in the past three decades and that little wage convergence occurs between the typical Mexican immigrant and the typical native worker. The data also suggest that the increasing importance of Mexican immigration is partly responsible for the deterioration in relative skills observed in the aggregate immigrant population, but that there has also been a decline in relative skills even among non-Mexican immigrants."     

Co-movements of GCC emerging stock markets: New evidence from wavelet coherence analysis

This paper examines the short term and long term dependencies between stock market returns for the Gulf Cooperation Council (GCC) Countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates) during the period 2005–2010. Our empirical investigation is based on the wavelet squared coherence which allows us to assess the co-movement in both time-frequency spaces. Our results reveal frequent changes in the pattern of the co-movements especially after 2007 for all the selected GCC markets at relatively higher frequencies. We further note an increasing strength of dependence among the GCC stock markets during the last financial crisis signifying enhanced portfolio benefits for investors in the short term relative to the long term. On the financial side, we uncover that the strength of co-movement between GCC markets may impact the multi-country portfolio's value at risk (VaR) levels. These findings provide potential implications for portfolio managers operating in the GCC region who are invited to consider co-movement through both frequencies and time when designing their portfolios.     

Distribution of wealth and incomplete markets: Theory and empirical evidence

This paper analyses the equilibrium distribution of wealth in an economy where firms’ productivities are subject to idiosyncratic shocks, returns on factors are determined in competitive markets, households have linear consumption functions and government imposes taxes on capital and labour incomes and equally redistributes the collected resources to households. The equilibrium distribution of wealth is explicitly calculated and its shape crucially depends on market incompleteness. With incomplete markets it follows a Paretian law in the top tail and the Pareto exponent depends on the saving rate, on the net return on capital, on the growth rate of population, and on portfolio diversification. The characteristics of the labour market crucially affects the bottom tail, but not the upper tail of the distribution of wealth in the case of completely decentralized labour market. The analysis also suggests a positive relationship between growth and wealth inequality. The theoretical predictions find a corroboration in the empirical evidence of United States in the period 1989-2004.     

Capital flight from the countries in transition: Some empirical evidence

This paper presents empirical evidence suggesting that the transition economies have tended to experience capital flight during periods of macroeconomic instability, such as high inflation and sharply declining output. The timing of these outflows, however, has differed somewhat across countries. Poland and Czechoslovakia experienced significant capital flight early in the transition process, but as reforms have progressed, capital outflows have slowed. By contrast, Russia registered a relatively steady flow of capital flight from 1991-94, with cumulative outflows totalling about $40 billion. Finally, capital flight from Hungary has been subdued, paralleling the gradual course of economic reforms and the country's comparative political stability.
