Business groups—confederations of legally independent firms—are ubiquitous in emerging economies, yet very little is known about their effects on the performance of affiliated firms. We conceive of business groups as responses to market failures and high transaction costs. In doing so, we develop hypotheses about the effects of group affiliation on firm profitability: affiliation could either boost or depress firm profitability, and members of a group are likely to earn rates of return similar to other members of the same group. Using a unique data set compiled largely from local sources, we test for these effects in 14 emerging markets: Argentina, Brazil, Chile, India, Indonesia, Israel, Mexico, Peru, the Philippines, South Africa, South Korea, Taiwan, Thailand, and Turkey. We find evidence that business groups indeed affect the broad patterns of economic performance in 12 of the markets we examine. Group affiliation appears to have as profound an effect on profitability as does industry membership, yet strategy scholars have a much clearer grasp of industries than of groups. Moreover, membership in a group raises the profitability of the average group member in several of the markets we examine. This runs contrary to the wisdom, conventional in advanced economies, that unrelated diversification depresses profitability. Overall, our findings suggest that the roots of sustained differences in profitability may vary across institutional contexts; conclusions drawn in one context may well not apply to another.

This article studies the performance of the high-order moment capital asset pricing model (CAPM) market models in emerging markets. We apply the cubic market model (4-moment CAPM) to 16 emerging market stock indices ranging from January 2010 to September 2015. Performance of the model is evaluated through the Fama and MacBeth’s two-step regression and through different corrections proposed in the literature, as well as generalized method of moments (GMM) estimation. According to Fama–MacBeth’s procedure, CAPM, the quadratic and cubic market models seem to be insignificant for the analyzed sample; however, the GMM estimation shows that quadratic model is valid for Indian, Polish, and Thai country indices, whereas cubic market model is accurate for Indian country index.  相似文献

This paper presents the case for and the evidence in favour of passive investment strategies and examines the major criticisms of the technique. I conclude that the evidence strongly supports passive investment management in all markets—small–capitalisation stocks as well as large–capitalisation equities, US markets as well as international markets, and bonds as well as stocks. Recent attacks on the efficient market hypothesis do not weaken the case for indexing.  相似文献

Measuring and predicting compliance with tax obligations is an important but challenging task. Survey data from California smokers show that several forms of tax avoidance and evasion were common. The analysis shows that 43% of smokers avoided taxes by purchasing cigarettes from out-of-state sources in the past year, 15% admitted to evading taxes through cross-border purchases, and 26% reported purchasing likely or certainly untaxed cigarettes in the state in the past month. Attitudinal factors related to tax morale explain much more of the variance in compliance rates than demographic or law-and-economics factors. The implications for policy are discussed.  相似文献

The martingale hypothesis is tested for 15 European emerging stock markets located in Croatia, the Czech Republic, Estonia, Hungary, Iceland, Latvia, Lithuania, Malta, Poland, Romania, Russia, the Slovak Republic, Slovenia, Turkey and the Ukraine. For comparative purposes, the developed stock markets in Greece, Portugal and the UK are also included. Rolling window variance ratio tests based on returns and signs and with wild bootstrapped p-values are used with daily data over the period beginning in February 2000 and ending in December 2009. The fixed-length rolling sub-period window captures changes in efficiency and is used to identify events which coincide with departures from weak-form efficiency and to rank markets by relative efficiency. Overall, return predictability varies widely. The most efficient are the Turkish, UK, Hungarian and Polish markets; the least efficient are the Ukrainian, Maltese and Estonian stock markets. The global financial market crisis of 2007–2008 coincides with return predictability in the Croatian, Hungarian, Polish, Portuguese, Slovakian and UK stock markets. However, not all markets were affected: the crisis had little effect on weak-form efficiency in stock markets located in Greece, Latvia, Romania, Russia and Turkey.  相似文献

在分拆上市和单独境外上市对中国资本市场的不利影响日益凸显的情况下,中央企业A股+H股整体上市是兼顾企业利益和国家利益的现实选择。本文利用实证的研究方法,分析了中央企业先H股后A股、A股+H股同步和先A股后H股三种整体上市路径以及中央企业A股+H股整体上市对中国资本市场的影响,得出的结论是,三种中央企业A股+H股整体上市路径都能对我国资本市场的发展产生或多或少的积极影响;同时,中央企业A股+H股整体上市对包括中国香港在内的中国资本市场将产生多方面的积极影响。  相似文献

Levels of insurance against unemployment vary considerably across countries. Replacement rates, the ratio relating income from unemployment to what people earned when they were employed, are higher in countries with proportional electoral systems than in countries with majoritarian systems. Also, replacement rates are positively correlated with per capita income and negatively correlated with the countries' unemployment rates. I develop an electoral competition model that replicates these stylized facts.  相似文献

This paper investigates the causal links between stock market performance and consumption for five Asian economies by applying the bound tests of Pesaran et al. and lag augmented VAR of Toda and Yamamoto . We find two‐way causal relationships between stock market performance and consumption in the cases of Hong Kong and Taiwan in the long run. The existence of such two‐way causal links indicates that stock market performance and consumption mutually affect each other, implying that the previous studies may have overestimated the wealth effect of the stock markets without taking account of the reverse causation from consumption to the stock markets. The short‐run effect of the stock market on consumption is more visible than the long‐run effect in most of the sample economies, suggesting that changes in consumption directly reflect stock market fluctuations.  相似文献

We analyse the optimal location choice of a monopolistic firm that operates two arbitrarily located platforms on a two‐sided market. By extending the traditional Hotelling framework, we show that the optimal platform locations are equivalent to the one‐sided benchmark if both sides are either restricted to single‐ or multi‐homing. In the mixed case (one side single‐homes, the other one multi‐homes), the optimal platform locations are in line with the respective symmetric case. If the monopolist is restricted to choosing the same location on either side of the market, the optimal locations are determined by the relative profitability of the market sides.  相似文献
