Technological expectations and adoption of improved technology

Attention is focused upon the adoption (demand) rather than the creation (supply) of new technology, which improves from time to time. Based on the expected flow of technological progress over which the firm (demander) has no control, it must decide either to adopt the current best available technology or to postpone adoption. The distinguishing features of the model are that more than one technological innovation is anticipated and expectations about the likelihood of such innovations are revised as time passes since the last innovation. Our analysis shows that the firm will adopt the current best practice if its technological lag exceeds a certain threshold; moreover, as time passes without new technological advances it may become profitable to purchase a technology that has been available even though it was not profitable to do so in the past.     

Auditors as modern pharmakoi: Legitimacy paradoxes and the production of economic order

Despite a continuous flow of audit failure episodes the auditing profession keeps on being seen as technically and morally legitimate. This paper seeks to better understand how the paradox that surrounds the legitimacy of financial auditing develops. Relying on René Girard's theoretical developments on scapegoating, sacrificial rituals and mythification, we argue that auditors are often (but not always) selected as sacrificial victims in the wake of major corporate scandals. Rationalized mythologies are mobilized in the process by which auditors are morally and/or legally condemned, in a way which maintains or strengthens the legitimacy of the financial audit function. Fundamentally speaking, we contend that financial auditors can be conceived of as modern pharmakoi, constituting a reservoir of victims to sacrifice whenever fraudulent financial statements surfacing in the public arena threaten to severely disrupt the credibility and smooth-functioning of capital markets. We confront our theoretical translation of Girardian theory to the empirical domain through an analysis of the breakdown of accounting firm Arthur Andersen, in which we examine how the legitimacy paradox surrounding the financial audit function is produced and reproduced. One of our key conclusions is as follows: despite claims which commonly celebrate the rationality of capital markets, the latter's functioning and the sustaining of economic order are predicated on the production and reproduction of mythologies.     

Threshold Effects in Cointegrating Relationships*

In this paper, we introduce threshold‐type nonlinearities within a single‐equation cointegrating regression model and propose a testing procedure for testing the null hypothesis of linear cointegration vs. cointegration with threshold effects. Our framework allows the modelling of long‐run equilibrium relationships that may change according to the magnitude of a threshold variable assumed to be stationary and ergodic, and thus constitutes an attempt to deal econometrically with the potential presence of multiple equilibria. The framework is flexible enough to accommodate regressor endogeneity and serial correlation.     

Creating new growth platforms

Sooner or later, most companies can't attain the growth rates expected by their boards and CEOs and demanded by investors. To some extent, such businesses are victims of their own successes. Many were able to sustain high growth rates for a long time because they were in high-growth industries. But once those industries slowed down, the businesses could no longer deliver the performance that investors had come to take for granted. Often, companies have resorted to acquisition, though this strategy has a discouraging track record. Over time, 65% of acquisitions destroy more value than they create. So where does real growth come from? For the past 12 years, the authors have been researching and advising companies on this issue. With the support of researchers at Harvard Business School and Insead, they instituted a project titled "The CEO Agenda and Growth". They identified and approached 24 companies that had achieved significant organic growth and interviewed their CEOs, chief strategists, heads of R&D, CFOs, and top-line managers. They asked, "Where does your growth come from?" and found a consistent pattern in the answers. All the businesses grew by creating new growth platforms (NGPs) on which they could build families of products and services and extend their capabilities into multiple new domains. Identifying NGP opportunities calls for executives to challenge conventional wisdom. In all the companies studied, top management believed that NGP innovation differed significantly from traditional product or service innovation. They had independent, senior-level units with a standing responsibility to create NGPs, and their CEOs spent as much as 50% of their time working with these units. The payoff has been spectacular and lasting. For example, from 1985 to 2004, the medical devices company Medtronic grew revenues at 18% per year, earnings at 20%, and market capitalization at 30%.     

Proto-coalition bargaining and the core

In the proto-coalition model of government formation, formateur F appoints a proto-coalition and asks its members whether to start negotiating a coalition contract. If all accept, then the proto-coalition forms and starts negotiating; otherwise, a caretaker government assumes office. I extend this model by allowing F to revise the chosen proto-coalition after rejections, that he states pre-conditions for the subsequent negotiations, and that F??s opponents may publicly pre-commit to accept/reject certain proposals. The set of equilibrium outcomes is identified as the core if F??s opponents can pre-commit and as the convex hull of the core if they cannot pre-commit credibly. This extended model eliminates two flaws of the standard model: it explains why F cannot always install his favored coalition (whatever the status quo) and why ??important?? coalition members may have more bargaining power in the subsequent negotiations than others.     

Customer participation in service recovery: a meta-analysis

Research on customer participation in service recovery is surging, yet empirical examinations provide mixed results. A meta-analysis of 30 independent samples reported in 21 studies (N?=?7872) shows that the effect sizes for the relationships between customer participation in service recovery and customer outcomes are rather weak. We also find that customer participation in service recovery has an indirect effect on satisfaction with service recovery via distributive justice and procedural justice, but not via interactional justice. Conversely, customer participation in service recovery has an indirect effect on overall satisfaction via distributive justice and interactional justice, but not via procedural justice. Finally, the effectiveness of customer participation in service recovery is stronger when customers participate in the outcome of the recovery and for customers with an Eastern cultural background, but weaker when additional compensation is offered and in online settings.     

Intergenerational risksharing and equilibrium asset prices

In the presence of overlapping generations, a social security system, with contingent taxes and benefits, can affect both asset prices and intergenerational risksharing. In a simple model with two risky factors of production—human capital, owned by the young, and physical capital, owned by all older generations—a social security system that optimally shares risks exposes future generations to a share of the risk in physical capital. Such a system reduces precautionary saving and increases the riskbearing capacity of the economy. Under plausible conditions it increases the riskless interest rate, and lowers the price and risk premium of physical capital.
