The cross-section of returns in frontier equity markets: Integrated or segmented pricing?

Is asset pricing segmented or integrated in frontier equity markets? To answer this question, we examine the returns on more than 4500 stocks from 22 frontier countries for the years 1997–2018. We evaluate the performance of a few major asset pricing models. We document strong value and momentum effects but find no consistent evidence regarding size, investment, and profitability premia. The recent six-factor model of Fama and French (2018) outperforms other models and best explains the cross-sectional and time-series variation in returns. Our results point to low integration of frontier equities, even after the global financial crisis. Local risk factors explain the behavior of prices much better than their global counterparts do. The low correlation of these risk factors allows augmenting the efficient frontier of an international investor.     

Financial market liberalization and the pricing of idiosyncratic risk

We test the impact of idiosyncratic risk on stock returns for emerging markets that experience financial market liberalizations. Idiosyncratic risk is positively associated with returns prior to financial market liberalization, but liberalization diminishes this effect. Moreover, prior to liberalization, the number (concentration) of stocks available in the market is negatively (positively) correlated with the pricing of idiosyncratic risk. The decrease in the pricing of idiosyncratic risk can explain the reduction in the cost of capital around liberalizations. Additionally, the change in the pricing of idiosyncratic risk may be a useful measure of the success of financial market liberalization.     

Sector level cost of equity in African financial markets

This paper assesses the effectiveness of Liu (2006) metrics in measuring illiquidity within a multifactor CAPM pricing model. Costs of equity are estimated using this model for the major sectors within Africa's larger equity markets: Morocco, Tunisia, Egypt, Kenya, Nigeria, Zambia, Botswana and South Africa. In all countries, the cost of equity is found to be highest in the financial sector and lowest in the blue chip stocks of Tunisia, Morocco, Namibia and South Africa. At an aggregate level, Nigeria and Zambia have the highest cost of capital.     

Dynamic interdependence of ASEAN5 with G5 stock markets

We find ASEAN5 and G5 stock markets are weakly linked in normal conditions. ASEAN5 markets became more connected with G5 markets during global financial crisis, with stronger conditional correlations, a higher level of risk spillover-connectedness and intensive causal risk dependence. By implications, ASEAN5 stocks are both return enhancers and risk diversifiers in boom market conditions. The diversification benefits remain even during crisis times, albeit lesser. Over the longer term, the diversification benefits of a portfolio that includes both ASEAN5 and G5 stocks are recaptured as market linkages revert to some lower levels due to decreased crisis contagion.     

Oil and stock markets before and after financial crises: A local Gaussian correlation approach

The effect of financial shocks on the cross‐market linkages between oil prices (spot and futures) and stock markets is examined for four major crises. We employ the local Gaussian correlation approach and find that the two markets were regionalized for most of the 1990s and the early 2000s. Flights from stocks to oil occur in all crisis episodes, except the recent global financial crisis. The view that stock and oil markets behave like “a market of one” after the financialization of commodities is further supported by the presence of contagion between US stock markets and all the benchmark oil markets.     

How far have we come and where should we go after 30+ years of research on Africa's emerging financial markets? A systematic review and a bibliometric network analysis

In this study, we perform a systematic literature review and a bibliometric network analysis of studies on Africa's financial markets from 1992 to 2021. The findings are as follows. First, we observe a steady growth of financial markets research in Africa over the 30-year period under consideration, which is suggestive of increasing interest and commitment to research on financial markets in Africa. Additionally, we note a lack of collaboration between or among researchers of financial markets studies in Africa, which implies very little knowledge exchange, ideas sharing, and innovations. We identify seven major areas of research based on the thematic network and content analysis, which are as follows: (i) asset pricing, (ii) financial integration, (iii) contagion, herding and extreme global events, (iv) efficiency and predictability of stock returns, (v) market interdependencies-sources and channels, (vi) portfolio diversification and risk management strategies, and (vii) impact of economic and financial news. We offer several avenues for future research that can set the agenda for financial market research in Africa in the coming years.     

Pricing Experience Goods in Information Good Markets: The Case of eBusiness Service Providers

We study the pricing strategies of firms providing a service in experience good markets with switching costs. Using data on vendors providing “hosting and related services” at an early stage of the market, we test for pricing distortions that follow from oligopolistic competition with quality uncertainty and switching costs. We find that firms with a brand name charge a premium for their product – leveraging the reputation accumulated in closely related markets. As the theoretical literature suggests, we also find that the type of pricing distortions along the product line depends on consumers’ expectations about quality. If consumers underestimate the quality of the product, firms behave as if they discount introductory contracts in order to build trust, and later on markup upgraded contract. In contrast, firms that offer a quality level that is lower than consumers’ expectations markup initial contracts while discounting upgraded ones.     

Indian equity options: Smile,risk premiums,and efficiency

We study the pricing of equity options in India which is one of the world's largest options markets. Our findings are supportive of market efficiency: A parsimonious smile-adjusted Black model fits option prices well, and the implied volatility (IV) has incremental predictive power for future volatility. However, the risk premium embedded in IV for Single Stock Options appears to be higher than in other markets. The study suggests that even a very liquid market with substantial participation of global institutional investors can have structural features that lead to systematic departures from the behavior of a fully rational market while being “microefficient.”     

Dispersion in Analysts’ Earnings Forecasts and Market Efficiency

Recent studies show that firms with higher analysts’ earnings forecasts dispersion subsequently have lower returns than firms with lower forecasts dispersion. This paper evaluates alternative explanations for the dispersion–return relation using a stochastic dominance approach. We aim to discriminate between the hypothesis that some asset pricing models can explain the puzzling negative relation between dispersion and stock returns, and the alternative hypothesis that the dispersion effect is mainly driven by investor irrationality and thus is an evidence of a failure of efficient markets. We find that low dispersion stocks dominate high dispersion stocks by second‐ and third‐order stochastic dominance over the period from 1976 to 2012. Our results imply that any investor who is risk‐averse and prefers positive skewness would unambiguously prefer low dispersion stocks to high dispersion stocks. We conclude that the dispersion effect is more likely evidence of market inefficiency, rather than a result of omitted risk factors.     

Exchange Rate Effects on Domestic Prices in Bulgaria and Poland: Progress in Making Markets?

The economic liberalization which has occurred in Central and Eastern Europe (CEE) over the past 15 years generally has involved establishing domestic markets and privatizing state‐owned firms, both with the intention of integrating the CEE economies into the global economy and allowing the benefits of competition to be realized. We explore how well this has been accomplished in two countries, Poland and Bulgaria, and the domestic conditions that contribute to its accomplishment. The sensitivity of domestic markets to international shocks, as reflected in exchange rate effects on domestic prices, may be viewed as an indicator of how integrated a country’s markets are into the global economy, and a proxy for competition in those markets. In explaining variation in exchange‐rate pass‐through, we examine the impact of market structure, economic liberalization and infrastructure as factors contributing to the development of competitive markets. We find that although integration into global markets can significantly increase market competitiveness, domestic factors also play a significant role.     

Systematic risk in emerging markets: the D-CAPM

There is by now a growing literature arguing against the use of the CAPM to estimate required returns on equity in emerging markets (EMs). One of the characteristics of this model is that it measures risk by beta, which follows from an equilibrium in which investors display mean–variance behavior. In that framework, risk is assessed by the variance of returns, a questionable and restrictive measure of risk. The semivariance of returns is a more plausible measure of risk and can be used to generate an alternative behavioral hypothesis (mean–semivariance behavior), an alternative measure of risk for diversified investors (the downside beta), and an alternative pricing model (the downside CAPM, or D-CAPM for short). The empirical evidence discussed below for the entire Morgan Stanley Capital Indices database of EMs clearly supports the downside beta and the D-CAPM over beta and the CAPM.     

Flight-to-liquidity: Evidence from China's stock market

In an order-driven and strictly regulated stock market, illiquidity risks' effects on asset pricing should be highlighted, particularly in such extreme market conditions as those in China. This paper utilizes panel data from China's stock market in an attempt to answer whether the illiquidity risk in various dimensions—including price impacts, the transaction speed, trading volume, transaction costs, and asymmetric information—can explain stock returns. We find that almost all dimensions of stock illiquidity are positively associated with excess stock returns. More importantly, smaller, less-liquid stocks suffer more liquidity costs, providing a strong evidence for “flight-to-liquidity.” Additionally, the transaction costs and asymmetric information, denoted by bid-ask spreads, robustly account for these illiquidity effects on stock pricing and differ from the findings in the U.S. market. We also find that the “flight-to-liquidity” can partially explain the idiosyncratic volatility puzzle, investors' gambling, and herding psychologies. This study provides substantial policy implications in regulation and portfolio management for emerging markets.     

Currency Substitution and Price Endings: Right Digit Effect

ABSTRACT

The strategic manipulation of prices. rightmost digits has been a tactic used by retailers in the western world for decades. By studying the internationalization of pricing tactics in a global economy, our research adds a much needed contribution to the literature of price endings and pricing tactics in global markets. We find that at lower price levels, consumers exposed to a 99 ending price in a currency substitution market are more likely to purchase the product compared to consumers in the US market. At higher price levels, on the other hand, consumers in either market situation exhibit no change in purchase intentions. Thus, the 99 ending tactic has no effect on consumers when the product is expensive. The use of the right digit effect by managers in a currency substitution/ dollarized economy as a way of persuading consumers to buy is still likely to be more successful compared to the USA market. As such, firms in a dollarized economy should structure their pricing strategies while taking into consideration the type of product they are offering and the consumer market they are dealing with.     

Excess Risk Premia of Asian Banks

This paper develops a framework for gauging the risks of emerging market banks by using stock market data. Employing a multifactor asset pricing model that allows for time‐varying risk premia, we find the presence of large excess risk premia on Asian bank stocks, especially in those markets affected by the Asian financial crisis. We find that the excess risk premia appear to be negatively related to the degree of economic freedom of a country but positively related to its corruption level. Thus, our findings are consistent with the view that crony capitalism in Asia may have distorted the market mechanism or the systematic risk exposure of banks. This suggests that the excess risk premium provides useful information on risk exposure for opaque banking systems where quality accounting information is not available.     

Regional financial integration in the GCC

We investigate the extent of regional financial integration in the member countries of the Gulf Cooperation Council. Interest rate data show that convergence exists and that interest rate differentials are relatively short-lived—especially relative to other unified currency area and comparable to those of the Euro Area post 1999. Equity data using cross-listed stocks confirm that stock markets are fairly integrated compared to other emerging market regions, although price equalization is hampered by market illiquidity. The limited volume data available suggests that intra-GCC capital flows are sizeable.     

PORTFOLIO SELECTION WITH MONOTONE MEAN-VARIANCE PREFERENCES

We propose a portfolio selection model based on a class of monotone preferences that coincide with mean-variance preferences on their domain of monotonicity, but differ where mean-variance preferences fail to be monotone and are therefore not economically meaningful. The functional associated with this new class of preferences is the best approximation of the mean-variance functional among those which are monotonic. We solve the portfolio selection problem and we derive a monotone version of the capital asset pricing model (CAPM), which has two main features: (i) it is, unlike the standard CAPM model, arbitrage free, (ii) it has empirically testable CAPM-like relations. The monotone CAPM has thus a sounder theoretical foundation than the standard CAPM and a comparable empirical tractability.     

Regime Dependent Sensitivity of Country Exchange Traded Funds to Common Risk Factors

If common factors jointly affect country stock markets, it is an indication of global stock market integration. Common factors may affect some markets more/less than other markets, an indication of the degree of global stock market integration/ segmentation. In this paper, we study the integration of global stock markets based on the returns on exchange traded funds (ETFs) for the US, Canada, UK, Germany, France, Italy, Australia and Japan. The relationship between country ETF returns and common risk factors may be time-varying across countries, and that favors a regime switching (RS) factor model for the dynamics of the country ETF returns. A RS factor model for the relationship between country ETF returns and common risk factors is fitted to daily data for the period from May 31, 2000 to March 31, 2014. We use the data to test a hierarchy of hypotheses on country ETF returns: (1) common factor exposure across all country ETFs and all regimes; (2) common factor exposure across some country ETFs and all regimes, and (3) common factor exposure across some country ETFs and some regimes. The RS factor model for ETF returns fits the data well and the common factors have variable effects across countries and over regimes.     

Monetary Policy,Vagabonding Liquidity and Bursting Bubbles in New and Emerging Markets: An Overinvestment View

‘Capitalism without failure is like religion without sin’. Charles Kindleberger's book Manias, Panics and Crashes points out that speculation and crises have always been present: the world economic crisis of the 20th century, the South Sea bubble in the 18th century, and the tulip mania in the first part of the 17th century. Starting with the Japanese bubble in the 1980s we take the reader on a tour through 20 years of bubbles in emerging markets and industrial countries which have recently culminated in the 2007/08 US subprime market crisis. We explain the global stock market and real estate booms based on the real and monetary overinvestment theories of Hayek, Wicksell and Schumpeter, arguing that ample liquidity supply originating in the large industrialised countries has contributed – independent from the exchange rate regime – to overinvestment cycles in new and emerging markets around the globe. The policy implication is to keep interest rates not too low for too long in response to bursting bubbles.     

Empirical evidence on cross-listed stocks of Central and Eastern European companies

This paper empirically investigates cross-listing's implications for companies in the newly-established capital markets in Central and Eastern Europe. Central and Eastern European companies face small capitalisation of local markets, limited liquidity and poor effectiveness of legal systems, all of which can have detrimental effects on stock pricing. We find that companies which issue Depositary Receipts and enter foreign markets experience a permanent value enhancement of about 26% around the event. We also observe that foreign listing significantly improves home market liquidity, which suggests that cross-listing helps to draw the interest of new investors and encourages them to start trading in both foreign and local markets. Moreover, we find that the pricing efficiency increases after foreign listing, which is reflected in reduced stock return autocorrelation.     

Derivatives trading,volatility spillover,and regulation: Evidence from the Korean securities markets

Unlike the U.S. and Japanese securities markets, we find new evidence of volatility spillover between index stocks and non‐index stocks following the introductions of index derivatives trading in the Korean securities markets. We further find that the degree of volatility spillover is closely related to the level of market deregulation; significant return volatility spills over from non‐index to index stocks during deregulation period but in the opposite direction during post‐deregulation period. Our empirical results show that the former volatility spillover from non‐index to index stocks can be explained by the transitory contagion effect associated with the 1997 Korean financial crisis and the subsequent market deregulation, whereas the latter volatility spillover from index to non‐index stocks is attributed to the permanent information spillover effect. This latter evidence suggests that the information regarding investors' expectations on the future common market factors is first reflected into the return volatility of index stocks and then transferred to the trading of non‐index stocks against which derivatives are not traded. Our results are robust to different estimation and sample construction methods. © 2009 Wiley Periodicals, Inc. Jrl Fut Mark 29:563–597, 2009
