Investigating the Not Invented Here (NIH) syndrome: A look at the performance, tenure, and communication patterns of 50 R & D Project Groups

The study, carried out in a large laboratory, shows that performance increases up to 1. 5 years tenure, stays steady for a time but by five years has declined noticeably. This tendency is best accounted for by the marked decline in communication rate among group members and between them and critical external sources of information. The authors analyse the significance of this finding and suggest means of maintaining the vitality of long-standing project teams.

Testing for Mean-Variance Spanning with Short Sales Constraints and Transaction Costs: The Case of Emerging Markets

We propose regression-based tests for mean-variance spanning in the case where investors face market frictions such as short sales constraints and transaction costs. We test whether U.S. investors can extend their efficient set by investing in emerging markets when accounting for such frictions. For the period after the major liberalizations in the emerging markets, we find strong evidence for diversification benefits when market frictions are excluded, but this evidence disappears when investors face short sales constraints or small transaction costs. Although simulations suggest that there is a possible small-sample bias, this bias appears to be too small to affect our conclusions.     

The Solution of Updating or Regionalizing a Matrix with both Positive and Negative Entries

Normally, when updating or regionalizing input-output matrices with negative entries, the negative numbers are first brought outside the matrix, then the matrix is updated or regionalized, then the negative numbers are added back to the result. This is theoretically, and sometimes also empirically, a rather unsatisfactory procedure. This paper proposes a theoretically sound alternative for the presently used ad hoc procedure. Based on the first-order conditions of a restated information loss problem, we generalize the RAS-procedure using reciprocals of the exponential transformations of the related Lagrange multipliers. The diagonal matrices that update or regionalize a given matrix optimally are the solutions of a fixed-point problem. To derive a numerical solution, the paper presents the GRAS-algorithm, which is illustrated in terms of a simple updating example.     

Money-supply turbulence and exchange-rate turbulence: Some empirical results

The purpose of this paper is to present the results of a simple empirical test of the hypothesis that volatile money supplies have led to volatile exchange rates. The results suggest that while there may exist a broad positive relation between money supply and exchange-rate volatility, it may not be discernible for small variations in turbulence.     

An Empirical Exploration of Decision-making Under Agency Controls and Stewardship Structure

abstract Two theories have emerged in the managerial control literature as to the best way for organizations to ensure that managers are acting in the firm's best interest: agency theory, which stresses controlling decision‐makers through monitoring and incentives aligned with organizational goals, and stewardship theory, which stresses that decision‐makers will act in the organization's best interest even in the absence of controls. Much of the research investigating the utility of these two positions is based on archival data where actual decision‐making can only be inferred. In this study, we utilize a laboratory methodology in order to determine if decision‐makers actually make different decisions when under the types of control (or lack thereof) suggested in these two theories. The results of this study show that individuals under agency controls invest more in alternatives that maximize profits of an organization than individuals under stewardship controls.     

The Role of Value‐Informed Pricing in Market‐Oriented Product Innovation Management*

Although the positive effect of a market orientation on new product success is widely accepted and the market orientation literature has increased its understanding of how a market orientation leads to performance, the extant literature has overlooked the role of value‐informed pricing in the relationship. Value‐informed pricing is a pricing practice in which the decision makers base the price of the new product on the customers' perceptions of the benefits that the product offers and how these benefits are traded by customers against the price (that has yet to be determined). Considering that pricing mistakes may hit hard on the profitability of product innovations, it is important to firms to have a good understanding of its role. This study develops a framework in which value‐informed pricing is integrated in the relationship between market orientation and new product performance. A distinction is made between customer and competitor orientations, and relative product advantage is also included in the conceptual model. The model is tested on data obtained from managers based on a cross sectional sample of 144 firms. The respondents were involved in a decision‐making process of the pricing of a new product. The model is tested using structural equations modeling. The results show that value‐informed pricing has a strong effect on new product performance. It also reveals that each component of a market orientation fulfills a specific role in a market‐oriented organization. Value‐informed pricing is found to have important mediating effects in the market orientation–new product performance relationship. Results show that firms with a strong customer orientation engage in value‐informed pricing and develop superior benefits to customers in an advantageous product. In turn, both value‐informed pricing and relative product advantage positively affect new product market performance. However, no significant effect of competitor orientation on value‐informed pricing is found. Combined with the finding that competitor orientation negatively affects relative product advantage, this suggests that competitor orientation may hurt new product performance when this orientation is not balanced with a strong customer orientation. The results also portray that value‐informed pricing leads to higher product advantage. Interestingly, this relation is contingent on the degree of interfunctional coordination within the firm. This suggests that the relationship between market orientation and new product performance is strongest if firms integrate value‐informed pricing in the new product development process. In this sense, a market‐oriented firm mirrors the customer value perception that makes a trade‐off between benefits and price.
