Survival of the Most Foolish of Fools: The Limits of Evolutionary Selection Theory

The paper investigates whether evolutionary selection, in nature or the market, ensures the survival of rational agents. It argues that once rationality appears, evolutionary selection can account for its diffusion—but cannot account for its appearance in the first place. This issue differs from the investigation of whether history matters. The issue of history or path-dependency focuses on whether evolutionary selection can favor the survival of the potentially most productive apparatus (in the biological or technological sense). To show this, the paper commences with the much-neglected difference between efficiency and productivity.

Contracts and Productive Information Gathering

We modify a standard Baron–Myerson model by assuming that, instead of knowing the state of nature, the agent has to incur a cost γ to learn it. Under these conditions, the principal will offer contracts that, depending on the value of γ, try to induce the agent to gather or not to gather information. We study the tradeoffs that are involved.Journal of Economic LiteratureClassification Numbers: D82, D83.     

Artificial decision-making and artificial ethics: A management concern

Expert systems are knowledge-based information systems which are expected to have human attributes in order to replicate human capacity in ethical decision making. An expert system functions by virtue of its information, its inferential rules, and its decision criteria, each of which may be problematic. This paper addresses three basic reasons for ethical concern when using the currently available expert systems in a decisions-making capacity. These reasons are (1) expert systems' lack of human intelligence, (2) expert systems' lack of emotions and values, and (3) expert systems' possible incorporation of intentional or accidental bias. For these reasons artificial ethics seems to be science fiction. Consequently, expert systems should be used only in an advising capacity and managers should not absolve themselves from legal and ethical responsibility when using expert systems in decision making.Omar E.

Vertical Integration,Foreign Multinationals and Stigler's Hypotheses: An Empirical Test Using Malaysian Data*

In this paper the hypotheses on motives for vertical integration as proposed by Stigler are empirically tested using a panel dataset from Malaysian manufacturing under both fixed‐effects and random‐effects specifications. Because the degree of multinational participation is expected to influence the results of the regression estimates, empirical tests are conducted with and without controlling for the effect of foreign firms’ participation. Depending on model specifications, evidence is found in favor of Stigler's hypotheses where vertical integration is positively related to demand growth and industry concentration. This result is generally consistent with those found in other vertical integration studies. Significantly, the coefficient estimates of the growth variable are not significant and biased downwards if there is no control on the effect of foreign multinationals in the estimation process.     

Construct validation of an Arabic version of the Learning Transfer System Inventory for use in Jordan

The purpose of this study was to translate and validate an Arabic version of the Learning Transfer System Inventory (LTSI) for use in Jordan. The study also investigated the perceptions of transfer system characteristics across selected individual and situational variables. The LTSI was administered to 450 employees of 28 different public and private sector organizations operating in Jordan. Principal axis factoring with oblique rotation was used to uncover the underlying structure of the Arabic version of the LTSI. Results showed a latent factor structure that is highly consistent with the English version of the LTSI. Results also indicated that transfer system perceptions differed across levels of education, years of experience, types of training, choice of training, sector of the organization and task of the organization. Implications for the field of human resource development are also provided.     

LEVERAGED BUYOUTS AND SHAREHOLDER RETURNS

This study examines the risk-adjusted stock returns realized by shareholders of firms acquired through leveraged buyouts to assess the economic gains associated with this type of acquisition. Stockholders of firms acquired through leveraged buyouts realize significant positive abnormal returns as a result of the buyout announcement. The findings support the notion of value creation in leveraged buyouts.     

Does Zero Tillage Improve the Livelihoods of Smallholder Cropping Farmers?

The biophysical benefits of zero tillage (ZT) are well documented in the literature. However, the literature on its economic benefits, especially in the context of small and medium‐scale farmers in the temperate developing world is scanty. Using a study of 621 wheat farmers in Syria, we provide empirical evidence on the impacts of adoption of ZT on farm income and wheat consumption. We use propensity score matching (PSM) and endogenous switching regression (ESR) approaches to account for potential selection biases. After controlling for confounding factors, we find that adoption of the ZT technology leads to a US$ 189/ha (33%) increase in net crop income and a 26 kg (34%) gain in per capita wheat consumption per year (adult equivalent) – an indication of meaningful changes in the livelihoods of the farm households. Besides the biophysical and environmental benefits documented elsewhere, our results suggest that adoption of ZT can also be justified on economic and food security grounds. Therefore, ZT can have sizeable impacts in transforming the agricultural sector in the temperate developing world provided that the technology is well promoted and adopted.     

The performance implications of power–trust relationship: The moderating role of commitment in the supplier–retailer relationship

The current research examines how coercive power and non-coercive power affect trust and how these relationships are affected by affective and calculative commitment. It also expands the understanding of the role of an under-researched dimension of performance, i.e., strategic performance, and studies it as a mediating variable in the relationship between trust and financial performance. The proposed model is empirically tested using Partial Least Squares (PLS) in supplier–retailer channel in Taiwan. The findings reveal that affective commitment has a positive moderating effect on the negative relationship between coercive power and trust, while calculative commitment has a negative moderating effect on the positive relationship between non-coercive power and trust. The results also indicate that strategic performance partially mediates the effect of trust on financial performance. The research advances theoretical understanding on the complex power–trust relationship and provides insights into the role of commitment in both enabling and undermining channel relationships. The findings highlight the importance of building affective commitment in channel relationships and the critical role of strategic performance in the trust–financial performance relationship.
