New Product Idea Activities in Large Technology Based Firms

In a previous article, Norman McGuinness developed a model of idea generation processes used by small firms. Here he reports similar patterns for larger firms but adds a stage he labels problem definition. Since his model describes the progress of ideas through various predevelopment stages, this article yields additional insight into better management practices. It emphasizes that search involves a system of social activities within the organization and also distinguishes between planned and unplanned search, structured versus unstructured procedures and top-down versus bottom-up orientation.     

Technological change and factor mix over the product cycle: A model of dynamic comparative advantage

This paper presents a simple dynamic model of how, for a given set of factor prices, the optimizing mix of factor inputs changes over a product cycle, and of how (as a result) comparative advantage in international trade shifts. The model is designed to be consistent with, and to explain, the following stylized facts. When a new technology comes into being, follow-on improvements of the original basic design tend to occur at a rapid rate. Opportunities for improvement and the nonroutinized nature of the production process put a premium on flexibility and insight. As the technology settles down, the premium placed on problem solving ability declines, obsolescence of equipment occurs less rapidly, and unskilled workers and machinery are substituted for skilled workers.     

Kickstarting growth in bus patronage: Targeting support at the margins

This paper presents an assessment of the performance of the Kickstart and Bus Route Development Grant schemes in England and Scotland which aimed to move marginal or new bus services towards commercial operation. Three key aspects are addressed, namely: the bidding and implementation process; performance against objectives and the future potential of the approach. The evidence suggests that this form of transformational support appears to offer a better return than subsidy that supports the status quo or indeed patronage based support.     

Perceived value of interactive digital textbook and adaptive learning: Implications on student learning effectiveness

The authors studied the perceived value of an interactive digital textbook LearnSmart (McGraw-Hill Education, New York, NY) and examined its implications on adaptive learning and student learning effectiveness. Constructionism and constructivism provided the theoretical foundation. Data were collected from an American public university over three semesters. Multiple regression analysis results show that LearnSmart improves students’ perceived competency and their satisfaction with LearnSmart, thus increasing their perceived value of using LearnSmart. In addition, perceived value of LearnSmart varies across different course delivery formats and devices, while perceived challenge has no influence on perceived value. Pedagogical implications and future research directions are discussed.     

Civil economy: definition and strategies for sustainable well-living

The civil economy paradigm presented in this paper has two main characteristics. First, it identifies the philosophical roots of the limits of our socioeconomic system in the reductionist views of human beings, corporations, and well-being. The three reductionist views not only fail to capture an important part of the reality, but also produce poverty of sense of life (also defined as eudaimonic well-being) and of life satisfaction, thereby generating a suboptimal level of well-being. The civil economy paradigm proposes an alternative where it is acknowledged that (1) part of the individuals depart from purely self-regarding preferences and develop other-regarding and relational skills enabling them to overcome social dilemmas, (2) part of the productive system depart from the profit maximization paradigm and aim to satisfy the interests of a wider range of stakeholders beyond shareholders, and (3) well-being is, beyond GDP, the stock of cultural, environmental, spiritual, and economic resources that a community can enjoy. The second qualifying point of the civil economy paradigm is that it proposes a richer four-hand approach to political economy (as an alternative to the traditional two-hand approach) where actions of the traditional invisible hand of the market and the visible hand of institutions in solving failures are complemented and supported by the complementary action of the two additional hands of grassroot citizens’ participation and socially and environmentally responsible companies. In our paper, we explain and document that these two additional hands are already at work, thereby confirming that the reductionist hypothesis on individuals and corporations is rejected by empirical evidence. In the paper, we argue that the civil economy paradigm, by increasing social participation and generativity of all actors, has the power of bridging the gap between the current suboptimal and the socially optimal sense of life (well described in the concept of “common good”). We as well provide evidence showing that the paradigm is far from being unrealistic and that its sprouts are already working in several fields of our society, preparing a more thorough transformation and full replacement of the old paradigm at a theoretical level that is near to come.     

Alternative approximations of the bias and MSE of the IV estimator under weak identification with an application to bias correction

We provide analytical formulae for the asymptotic bias (ABIAS) and mean-squared error (AMSE) of the IV estimator, and obtain approximations thereof based on an asymptotic scheme which essentially requires the expectation of the first stage F-statistic to converge to a finite (possibly small) positive limit as the number of instruments approaches infinity. Our analytical formulae can be viewed as generalizing the bias and MSE results of [Richardson and Wu 1971. A note on the comparison of ordinary and two-stage least squares estimators. Econometrica 39, 973–982] to the case with nonnormal errors and stochastic instruments. Our approximations are shown to compare favorably with approximations due to [Morimune 1983. Approximate distributions of k$k$-class estimators when the degree of overidentifiability is large compared with the sample size. Econometrica 51, 821–841] and [Donald and Newey 2001. Choosing the number of instruments. Econometrica 69, 1161–1191], particularly when the instruments are weak. We also construct consistent estimators for the ABIAS and AMSE, and we use these to further construct a number of bias corrected OLS and IV estimators, the properties of which are examined both analytically and via a series of Monte Carlo experiments.
