An Exploratory Study on Nonlinear Causality Among the MILA Markets

According to conventional portfolio theory, an increase in the interconnectedness of international financial markets may reduce the potential for constructing diversified portfolios. This article explores the implications of the creation of the Latin American Integrated Market (MILA)¹ over the dependence structure of its members using correlation and cointegration analysis as well as linear and nonlinear Granger causality tests. The creation of MILA aimed to enhance the integration process that Latin American financial markets “naturally” present while still providing diversification opportunities to investors. The results of our empirical analysis suggest that such objective is being achieved. Evidence of a rise in cross-country linear correlations and their linear causal relationship supports the idea of an increasing financial integration process in the region, while the absence of cointegration and the weakening of the nonlinear causal relationship favors the creation of diversified regional portfolios. These findings provide valuable insights for investment portfolio designers, regulators, and supervisors.     

Mimicking repurchases

We study the tendency of firms to mimic the repurchase announcements of their industry counterparts. We argue that a firm, by repurchasing its shares, sends a positive signal about itself and a negative one about its competitors. This induces the competing firms to mimic the behavior of the repurchasing firm by repurchasing themselves. Using a broad sample of US firms from the period 1984–2002, we show that, in concentrated industries, a repurchase announcement lowers the stock price of the other firms in the same industry. The other firms react by repurchasing themselves to undo these negative effects. Repurchases are chosen as a strategic reaction to other firms’ repurchase decisions and are not motivated by the desire to time the market, i.e., to take advantage of a significantly undervalued stock price. Therefore, repurchasing firms in more concentrated industries experience a lower increase in value in comparison with their counterparts in less concentrated industries in the post-announcement era. Alternative methodologies used to estimate long-term performance confirm that it is only the repurchasing firms in low concentration industries that outperform the market, their non-repurchasing peers, and their counterparts in more concentrated industries by amounts that are economically and statistically significant.     

Augmented reality in marketing: Conceptualization and systematic review

This systematic review of the literature focuses on the use of AR and its impacts in the marketing area. It provides a multidisciplinary, up-to-date synthesis of the literature and an exhaustive classification of AR. Through the use of the SPAR-4-SLR protocol, 148 articles were selected for analysis. The study has three main objectives. First, it reports the key characteristics (distribution by year, publication outlets, etc.), theoretical models, and methodologies used in this research domain. Second, it suggests a classification of the types of AR according to their triggers and the object of the augmentation (self vs. external). Third, it proposes a framework that presents (1) the AR features and attributes and the AR use experience; (2) the cognitive, affective, and social mediators; and (3) the outcomes of these experiences. Key moderators (types of AR, types of products, individual characteristics, etc.) are also discussed. Using the TCCM framework (theories, context, characteristics, and methodologies), this study offers several future research avenues and highlights the importance of considering the effects of the different types of AR. Finally, it offers pointers for managers on how to develop efficient AR solutions and how these can be used to reduce a company's carbon footprint.     

Reintegrating Ethics and Institutional Theories

Organizational ethics and institutional theories are extended by recovering Weberian and Pre-Weberian theorizing that emphasized the joining of ethics and institutional theories. Understanding how ethics and institutional systems influence each other can advance our understanding of the nature and causes of structural organizational ethics issues and help guide potential reforms. We consider the interplay of these elements during the recession of 2008–2009, highlighting how structural ethics problems may have to be addressed at the institutional levels and not solely the individual or organizational levels.     

Do small shareholders count?

We hypothesize that age similarity among small shareholders acts as an implicit coordinating device for their actions and, thus, could represent an indirect source of corporate governance in firms with dispersed ownership. We test this hypothesis on a sample of Swedish firms during the 1995-2000 period. Consistent with our hypothesis, we find that compared with shareholders of differing ages, same-age noncontrolling shareholders sell more aggressively following negative firm news; firms with more age-similar small shareholders are more profitable and command higher valuation; and an increase (decline) in a firm's small shareholder age similarity brings a significantly large increase (decline) in its stock price. The last effects are more pronounced in the absence of a controlling shareholder.     

The role of institutional investors in propagating the crisis of 2007–2008

Using novel data on investors' bond portfolios, we study the contagion of the crisis from securitized bonds to corporate bonds. When securitized bonds became “toxic” in August 2007, mutual funds retained the now illiquid securitized bonds and sold corporate bonds. Funds with negative flows or high liquidity needs liquidated more than others. Yield spreads increased more for corporate bonds whose pre-crisis bondholders were more heavily exposed to securitized bonds, compared to same-issuer bonds held by unexposed investors. The findings suggest that liquidity-constrained investors with exposure to securitized bonds played a role in propagating the crisis from securitized to corporate bonds.     

Information flows within financial conglomerates: Evidence from the banks–mutual funds relation

We study how information flows within financial conglomerates by analyzing the relations between mutual funds and banks that belong to the same financial group. We investigate the effect that the lending behavior of affiliated banks has on the portfolio choice of the mutual funds that are part of the same group. We show that funds (fund families) increase their stakes in the firms that borrow from their affiliated banks in the period following the deal by far greater amounts than other unaffiliated funds (fund families). We provide evidence that this strategy is information-driven. The performance of the positions of affiliated funds in the stocks of borrowing firms exceeds that of their other positions in nonborrowing stocks located in the same industry as well as that of other stocks having similar characteristics by up to 1.6% per month. Funds increase (decrease) their stock holdings in those borrowing stocks that subsequently provide positive (negative) abnormal returns, suggesting that they exploit privileged inside information not available to other market participants. This behavior is prevalent largely in funds located in close geographic proximity to their lending banks. Furthermore, it is exhibited mostly by young, small, and poorly performing fund families. Our evidence points to information flows within conglomerates through informal channels such as personal acquaintances.     

Cosmetic mergers: The effect of style investing on the market for corporate control

We study the impact of “style investing” on the market for corporate control. We argue that the choice of the bidder is influenced by the fact that the merge with a firm that belongs to an investment style more popular with the market may boost the bidder's value. By using data on the flows in mutual funds, we construct a measure of popularity, which relies directly on the identification of sentiment-induced investor demand, rather than being a direct transformation of stock market data. We show that differences in popularity between bidder and target help to explain their pairing. The merger with a more popular target generates a halo effect from the target to the bidder that induces the market to evaluate the assets of the less popular bidder at the (inflated) market value of the more popular target. Both bidder and target premiums are positively related to the difference in popularity between the target and the bidder. However, the target's ability to appropriate the gain is reduced by the fact that its bargaining position is weaker when the bidder's potential for asset appreciation is higher. We document a better short- and medium-term performance of less popular firms taking over more popular firms. The bidder managers engaging in these cosmetic mergers take advantage of the window of opportunity induced by the deal to reduce their stake in the firm under convenient conditions.     

Financial Innovation and Information: The Role of Derivatives When a Market for Information Exists

We study the effects of financial innovation in a model of endogenousinformation acquisition. We determine the conditions under whichthe introduction of a derivative written on an existing stockincreases or decreases the incentive to purchase information.We show that financial innovation produces some effects whichhold across informational structures and others which differ.The former coincide with the few empirical results that arerobust in the literature (effects on prices, risk premia, andvolatility), while the latter coincide with the ones that differexperiment by experiment (effects on volume, correlation betweenvolume and volatility, and market informational efficiency).     

The Global Financial Crisis and Sub‐Saharan Africa: The Effects of Slowing Private Capital Inflows on Growth*

Abstract: This paper uses the bias‐corrected least‐squares dummy variable (LSDV) estimator to examine the relationship between economic growth and four different types of private capital inflows (cross‐border bank lending, foreign direct investment (FDI), bonds flows and portfolio equity flows) on a sample of 15 selected sub‐Saharan African countries over the period 1980–2008. Our results show that FDI and cross‐border bank lending exert a significant and positive impact on sub‐Saharan Africa's growth, whereas portfolio equity flows and bonds flows have no growth impact. Our estimates suggest that a drop by 10 per cent in FDI inflows may lead to a 3 per cent decrease of income per capita growth in sub‐Saharan Africa, and a 10 per cent decrease in cross‐border bank lending may reduce growth by up to 1.5 per cent. Therefore, the global financial crisis is likely to have an important effect on sub‐Saharan Africa's growth through the private capital inflows channel.
