Alliance Formation and Firm Value

Mots clés : firm alliances, matching, competitive advantage

We consider the formation of alliances that potentially create complementarities, that is, when the value function is super-modular in firm resources. We show that, in a frictionless world where information is perfect and managers optimize, firm alliances disproportionately increase the value of high-resource-level firms, resulting in higher variance and higher skewness of the distribution of firm value; moreover, higher-value alliances are subject to regression to the mean at a faster rate. These effects are magnified if the degree of complementarities is endogenously determined by each firm’s investment. We also consider alliances where matching and/or information about firm resources are imperfect, and show that complementarities are a necessary but not sufficient condition for alliances to cause an increase in firm value; and that complementarities are neither a necessary nor a sufficient condition for alliances to be correlated with higher firm value

An Integrative Model of the Influence of Parental and Peer Support on Consumer Ethical Beliefs: The Mediating Role of Self-Esteem, Power and Materialism

What causes adolescents to develop consumer’ ethical beliefs? Prior research has largely focused on the negative influence of peers and negative patterns of parent–child interactions to explain risky and unethical consumer behaviors. We take a different perspective by focusing on the positive support of parents and peers in adolescent social development. An integrative model is developed that links parental and peer support with adolescents’ self-worth motives, their materialistic tendencies, and their consumer ethical beliefs. In a study of 984 adolescents, we demonstrate support for a sequential mediation model in which peer and parental support is positively related to adolescents’ self-esteem and feelings of power, which are each associated with decreased materialism as a means of compensating for low self-worth. This reduced materialism is, in turn, associated with more ethical consumer beliefs

Bouncing Back: Building Resilience Through Social and Environmental Practices in the Context of the 2008 Global Financial Crisis

Mots clés : organizational resilience; social and environmental practices; strategic and tactical practices; global financial crisis; survival analysis

Even though organizational researchers have acknowledged the role of social and environmental business practices in contributing to organizational resilience, this work remains scarce, possibly because of the difficulties in measuring organizational resilience. In this paper, we aim to partly remedy this issue by measuring two ways in which organizational resilience manifests through organizational outcomes in a generalized environmental disturbance—namely, severity of loss, which captures the stability dimension of resilience, and time to recovery, which captures the flexibility dimension. By isolating these two variables, we can then theorize the types of social and environmental practices that contribute to resilience. Specifically, we argue that strategic social and environmental practices contribute more to organizational resilience than do tactical social and environmental practices. We test our theory by analyzing the responses of 963 U.S.-based firms to the global financial crisis and find evidence that support our hypotheses

We study whether R&D-intensive firms are more resilient to trade shocks. Wecorrect for the endogeneity of R&D using tax-induced changes to R&D cost. While rising imports from China lead to slower sales growth and lower profitability, these effects are significantly smaller for firms with a larger stock of R&D (by about half when moving from the bottom quartile to the top quartile of R&D). We provide evidence that this effect is explained R&D allowing firms to increase product differentiation. As a result, while firms in import-competing industries cut capital expenditures and employment, R&D-intensive firms downsize considerably less

Data abundance and asset price informativeness

Information processing filters out the noise in data but it takes time. Hence, low precision signals are available before high precision signals. We analyze how this feature affects asset price informativeness when investors can acquire signals of increasing precision over time about the payoff of an asset. As the cost of low precision signals declines, prices are more likely to reflect these signals before more precise signals become available. This effect can ultimately reduce price informativeness because it reduces the demand for more precise signals (e.g., fundamental analysis). We make additional predictions for trade and price patterns

Deciding about human lives: an experimental measure of risk attitudes under prospect theory

For public policies in the health, security or safety domains, the main consequences concern the number of human lives that are saved or lost, and are uncertain ex-ante. In classic economic evaluations of such policies, losses and gains of human lives are often monetized and aggregated with other costs and benefits. Uncertainty about human lives is thus treated as uncertainty about monetary consequences. In this paper, we question whether people risk human lives as they risk money.We present an experiment comparing risk attitudes towards human lives and towards money under prospect theory. The results show that respondents treat the two attributes differently when losses are involved. Specifically, the decisions involving human lives are characterizedby less elevated probability weighting in the loss domain and higher loss aversion compared to decisions involving money. These findings suggest that public preferences may differ from the cost-benefit analysis recommendations

Decision Theory Made Relevant: Between the Software and the Shrink

Decision theory offers a formal approach to decision making, which is often viewed and taught as the rational way to approach managerial decisions. Half a century ago it generated high hopes of capturing and perhaps replacing intuition, and providing the “right” answer in practically all managerial situations. Today it seems fair to say that decision theory has not lived up to these expectations. Behavioral science provides ample evidence that managers fail to follow the dicta of decision theory, even when these are explained to them. As a result, executives often find decision theory frustrating and useless and prefer to rely on their intuition. This paper suggests that this extreme conclusion is unwarranted and calls for a re-appraisal of decision theory. We propose that it should not always be regarded as a mathematical tool that produces the answer; rather, it can be viewed as a framework for a dialog between the decision maker and the decision theorist. In one extreme, the decision theorist studies the problem and provides the “correct’’ answer. But in another, the decision theorist only challenges the decision maker’s intuition and logic. In between, a whole gamut of possible dialogs exists, in which decision theory doesn’t replace intuition, but supports and refines it
