While many existing studies report that corporate diversification destroys shareholder value, several recent studies challenge these findings. Schoar [Schoar, A. (2002). Effects of corporate diversification on productivity. The Journal of Finance, 57, 2379?2403] finds that plants in conglomerates are more productive than those in comparable single-segment firms, although conglomerates are traded at discounts. Villalonga [Villalonga, B. (2004a). Diversification discount or premium? New evidence from the business information tracking services. The Journal of Finance, 59, 479–506; Villalonga, B. (2004b). Does diversification cause the “diversification discount”. Financial Management, 33, 5?27] employs a more comprehensive database and statistical techniques than those used in the prior studies, and shows that there is a diversification premium, rather than discount. This paper develops a model that highlights the costs and benefits of corporate diversification. The diversified firm trades off the benefits of more efficient resource allocation through its internal capital market against the costs of information rents to division managers, which are necessary for effective workings of the internal capital market. We provide an argument supporting Schoar's findings, and identify conditions under which there can be a diversification discount or a premium.  相似文献

We investigate the effect of intraday sentiment on subsequent stock returns. Mispricing caused by intraday sentiment is not corrected immediately; rather, it lasts for about 30 min. After 30 min, however, investor sentiment negatively affects stock returns, suggesting that mispriced stocks are at least partially but not entirely adjusted back to their fundamental values. We also show that the effect of intraday sentiment depends on the degree of arbitrage. Intraday sentiment has little effect on firms that are easy to arbitrage. For these firms, the difference in the one-minute returns of firms with high and low sentiment is nearly zero, implying that any mispricing caused by intraday sentiment is immediately corrected for this group of firms. In contrast, among firms that are hard to arbitrage, the difference in the returns of firms with high and low sentiment lasts for about half an hour. This difference in the effect of intraday sentiment is not caused by the firms’ liquidities.  相似文献

The corporate diversification literature presents a puzzle. Short-horizon event studies report positive abnormal returns around the announcement of a diversifying event, while studies that examine diversified firms find evidence that diversified firms are worth less than specialized firms (a diversification discount). If diversification is value destroying, perhaps the destruction occurs over longer periods than have been previously tested. This paper tests the hypothesis that diversifying firms have negative long-run abnormal performance following diversification by examining a sample of specialized firms that have a diversifying event from 1978 through 1998. The firms are tracked for up to five years past their diversification year. There is evidence that value is destroyed for small firms that diversify but enhanced for larger firms that diversify.

This study examines diversification of the activities of business organizations. The meaning of diversification has been ambiguous in many studies that have used the concept as a way of describing strategic resource allocation decisions within firms. Many previous studies of diversification have suffered from a number of deficiencies. Some studies have observed the consequences of firms’ resource allocation and made inferences about the influence of organizational and external environmental factors on managers’ decisions affecting diversification. Other studies, that have been concerned with investigating diversification from a focus within the firm, have often adopted a molecular approach, being concerned with a limited number of organizational or environmental characteristics. In an attempt to redress these deficiencies, a contingency theory framework is used to describe and, in part, explain the formulation of decisions affecting diversification. This involves developing an unambiguous definition of diversification, and identifying organizational and external environmental characteristics that may be used to aid understanding of why firms diversify their activities in different ways.  相似文献

Prior studies provide empirical evidence that dual class firms are discounted compared to single class firms due to the extraction of private benefits. This study examines the link between managerial entrenchment and the dual class discount. Using propensity score matching and conditioning for past underperformance, the paper shows that investors apply a greater discount to the value of dual class firms as the degree of managerial entrenchment increases. The impact of entrenchment on dual class discount is more pronounced when the CEO is the controlling shareholder compared to when the controlling shareholder is a director or the chairman of the board.  相似文献

ABSTRACT This paper examines the impact of the industrial and geographical diversification activities of developing country firms on their performance, and draws attention to the unique attributes of these firms and of the circumstances under which their diversification activities take place. The empirical analysis is based on data from 345 developing country firms. The findings suggest significant and positive association between industrial and geographic diversification and performance, and considerable variation of these relationships across developing regions and diversification strategies.  相似文献

The well-known “MAX effect” documents that stocks with high maximum daily returns in the past month underperform those with low maximum daily returns. We show that such an effect varies with firm-level political sentiment. Among firms with low political sentiment, the usual MAX strategy gives a monthly risk-adjusted return of 1.52% and is statistically significant. However, the MAX effect weakens substantially or even reverses for firms with high political sentiment. Our findings provide novel guidance for trading on the MAX effect. Moreover, the results challenge the usual sentiment-based explanation for the MAX effect. Further evidence suggests that the prospect theory or investors’ underreaction to news may be consistent with our findings, although these channels cannot empirically explain the impact of political sentiment.  相似文献

In markets where consumers have switching costs and firms cannot price‐discriminate, firms have two conflicting strategies. A firm can either offer a low price to attract new consumers and build future market share or a firm can offer a high price to exploit the partial lock‐in of their existing consumers. This paper develops a theory of competition when overlapping generations of consumers have switching costs and firms produce differentiated products. Competition takes place over an infinite horizon with any number of firms. This paper shows that the relationship between the level of switching costs, firms' discount rate, and the number of firms determines whether firms offer low or high prices. Similar to previous duopoly studies, switching costs are likely to facilitate lower (higher) equilibrium prices when switching costs are small (large) or when a firm's discount rate is large (small). Unlike previous studies, this paper demonstrates that the number of firms also determines whether switching costs are pro‐ or anticompetitive, and with a sufficiently large (small) number of firms switching costs are pro‐ (anti‐) competitive.  相似文献

It is difficult to predict the financial distress of unlisted public firms due to their longer disclosure cycle of accounting information and more inadequate continuity of market trading information compared to listed firms. In this paper, we propose a framework to predict the financial distress of unlisted public firms using current reports. Specifically, to better represent the meaning of current report texts, we propose a semantic feature extraction method based on a word embedding technology. Empirical results show that current reports contain more effective information for predicting the financial distress of unlisted public firms compared with periodic reports. In addition, semantic features extracted using our proposed method significantly improve the predictive performance, and their enhancing effect is superior to that of topic features and sentiment features. Our study also provides implications for stakeholders such as investors and creditors.  相似文献

Whereas a majority of previous research in the diversification literature has focused on the performance consequences of diversification strategy, this paper examines the reverse relationship, that is, the effects of a firm's prior performance on the choice between related and unrelated diversification. This paper empirically tests and confirms the view that there are systematic ex ante performance differences between firms diversifying into related businesses and firms diversifying into unrelated businesses. These findings imply that ex post performance differences between related and unrelated diversifiers, often reported in previous research, are largely attributable to these ex ante performance differences, not to diversification strategy per se.  相似文献

This paper aims to assess the impact of both geographic and industrial diversification of economic activities on the productivity performance of large European R&D Multinational Enterprises (MNEs). Based on the worldwide subsidiaries of these firms, we measure the performance of the firms according to their level of industrial diversification and globalisation that we proxy with the presence and importance of subsidiaries in the EU, North America and Asia–Pacific regions. The sample consists of large R&D firms that represent about 80 % of total European R&D. In general, the results indicate a positive impact from globalisation on firms’ R&D productivity, especially in the US, while a negative impact for industrial diversification is found.  相似文献

This paper examines the links between product diversification, international diversification and capital structure for a panel of medium and large Italian firms. The results indicate that the interaction between these two dimensions of diversification strategy has a negative and significant impact on leverage. Furthermore, debt maturity analysis reveals that firms pursuing a simultaneous dual diversification strategy have, in particular, lower long‐term debt ratios. Our findings support the hypothesis that the complexity that comes from diversification reduces debt levels. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

This study analyses technological expansion by examining the interaction between firms' diversification strategy and internal capabilities. We argue that when new technologies emerge, firms that were actively pursuing diversification do not have equal intention to adopt the technologies. For firms that possess internal capabilities similar or relevant to the new technologies, their diversification strategy facilitates technological expansion, otherwise diversification strategy negatively affects technological adoption. This study improves our understanding on technological expansion. Existing studies try to identify organizational characteristics that facilitate or impede firm entry into new technological fields. This research reveals that the same organizational characteristic (e.g. diversification strategy) can exhibit different effects on technological adoption. It facilitates technological expansion if firms' existing capabilities can be applied to new technologies, otherwise it impedes new technological adoption.  相似文献

This paper examines how the sentiment of firm-specific news affects CDS spreads conditional on the degree of information asymmetry. Using a large set of news releases, we document a strong negative relationship between the sentiment of firm-specific news and CDS spreads. More importantly, consistent with the role of public news in reducing information asymmetry, we find evidence that the relation between news sentiment and CDS spreads is stronger for firms with higher information asymmetry. Furthermore, the relation is stronger for news with negative sentiment and during the 2008 financial crisis. Our results are robust to alternative sentiment measures.  相似文献

Using a two‐period switching cost model, this paper compares rental profit with sales profit in a framework in which duopolists produce horizontally differentiated durable goods. Rental firms use maintenance contracts that stipulate that repeat customers pay a lower fine per unit of damage than do those customers who switch to a rival firm. In the sales regime, firms give loyal customers a discount on their second period prices. If switching costs are zero, sales profit equals rental profit. For positive and identical switching costs, either regime can dominate. As the exogenous rate of depreciation falls, rental profit exceeds sales profit.

In this paper some of the results emerged in the empirical literature on diversification are put into perspective against the background of a simple integrative model of multiproduct firms. By letting diversification strategies depend on the simultaneous play of four factors (demand relationships and technological links between goods, collusion within a market and across markets), the latter provides an illustrative framework which is useful to discuss how effectively the issue of ambiguous findings has been tackled in applied works. In some cases scholars have devoted substantial effort in order to build tests which can successfully discriminate among the different views on the causes and effects of diversification, while in other circumstances empirical investigations have been conducted with much less care. Other then criticising some of the methods used in the past, the paper provides a number of suggestions that can help guiding future empirical work on corporate diversification.

This article uses the structure/conduct/performance framework as an underpinning to investigate the attributes of turnaround firms. Turnaround is defined as a substantial improvement of the firms's return on assets relative to the average return of its industry. Industry and firm structural characteristics including concentration, industry growth, R&D, advertising, market share, size, diversification, capital intensity and margins are identified. The results of a series of univariate and multivariate tests run on a sample of turnaround and non-turnaround firms indicate that size, R&D, and an interaction between operating margin and advertising can be helpful in explaining some turnaround situations.  相似文献

In order to strengthen the debate on the foundations of aggregate business cycles, the science of macroeconomics has recently benefited from a series of contributions that emphasize the complex nature of collective human action. Progressively, agent heterogeneity, local interaction, sentiment formation and out-of-equilibrium dynamics are becoming central pieces on the analysis of short-term business fluctuations. This paper offers a contribution to this new literature by exploring a macro framework where endogenous fluctuations emerge regardless from the occurrence of shocks to technology or preferences. The proposed setting separates firms into two groups, which follow different wage setting strategies. The firms may systematically change from one class of wage setters to the other following local interaction rules and by making a global assessment of the profitability of each of the wage setting alternatives. Under reasonable parameterizations, long-term large periodicity cycles are generated; these cycles might constitute a meaningful component of the observed output gap and price level volatility, a component that complements the typical view on exogenous disturbances over an otherwise stable economy.  相似文献

Which is more innovative: the decentralized, diversified firm, or the centralized, more narrowly focused firm? The economics and finance literatures argue that diversified firms have innovation advantages as their operating units have access to an internal capital market. In contrast, the strategy and entrepreneurship literatures argue that managers of these firms suffer from “managerial myopia,” discouraging them from investing in projects with long-term, uncertain payoffs. We take a fresh look at the relationship between innovation and diversification using a comprehensive sample of diversified and nondiversified firms and a novel approach that teases out the mechanisms influencing the relationship between diversification and innovation. Consistent with conceptual and empirical work in strategy, we find a robust negative correlation between diversification and R&D intensity, suggesting that diversification reduces innovation by discouraging investment. However, our analysis suggests that internal capital market inefficiencies, rather than managerial myopia, is responsible for this observed negative relationship.  相似文献
