Continuity,Change, and New Product Performance: The Role of Stream Concentration*

Product development teams often face the challenge of designing radically new products that cater at the same time to the revealed tastes and expectations of existing customers. In new product development projects, this tension guides critical choices about continuity or change concerning product attributes and team composition. Research suggests these choices interact, but it is not clear whether they are complements or substitutes and if the level of change in one should match or not the level of change in the other. In this article, we examine the interaction between product attribute change, team change, and a new team-level factor, which we term stream concentration, as it captures differences among team members in terms of familiarity with the knowledge domain of the new product being developed. We measure stream concentration as team members’ prior NPD experience within a given set of products and assess its impacts on the management of change in new product development projects using longitudinal data from the music industry. We analyze 2621 new product development projects between 1962 and 2008 involving 34,265 distinct team members. Results show that stream concentration is a critical factor in new product development projects that, together with product attributes and team composition, affects new product performance. We discuss implications for research and practice.

Online Reputation Monitoring: An Exploratory Study on Italian Hotel Managers’ Practices

This study aims to understand current Italian hotel managers’ practices in monitoring online reviews included on travel websites and online travel agencies. Results obtained by a web survey indicate what hotel managers monitor (rating, rankings, guest comments regarding different service elements) and managers’ orientation in replying to customer reviews. Findings may support online reputation management tools providers and consulting firms by highlighting the degree of hoteliers’ interest in UGC monitoring and providing insights on possible factors that differentiate current management practices and should be considered in order to offer technical solutions coherent with the distinctiveness of Italian context.     

R&D Corporate Planning: Selecting the Core Technological Competencies

This paper deals with the selection of a firm's technological competencies on which to concentrate development efforts in a long term view. The perspective is that of corporate R&D which has to identify the technological competencies relevant to future competition and select those core for the firm. This process faces a major challenge, especially to put together different issues relevant to the problem: identify future scenarios and predict how new industries will be shaped, evaluate the potential of future markets, estimate the role and relevance of the technologies involved, identify a balanced set of technologies. This paper proposes a comprehensive methodology to support the process of selection of core technological competencies.     

Financial market equilibria with cumulative prospect theory

The paper first shows that financial market equilibria need not to exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. This is due to the boundary behavior of the cumulative prospect theory value function, which might cause an infinite short-selling problem. But even when a non-negativity constraint on final wealth is added, non-existence can occur due to the non-convexity of CPT preferences, which might cause discontinuities in the agents’ demand functions. This latter observation also implies that concavification arguments which has been used in portfolio allocation problems with CPT preferences do not apply to our general equilibrium setting with finite many agents. Existence of equilibria is established when non-negativity constraints on final wealth are imposed and there is a continuum of agents in the market. However, if the original prospect theory is used instead of cumulative prospect theory, then other discontinuity problems can cause non-existence of market equilibria even in this case.     

The effects of environmental policies on the abatement investment decisions of a green firm

This paper focuses on environmental policies aimed at rising investment in pollution abatement capital. We assume that ecological uncertainty, i.e., uncertainty over the dynamics of pollution, affects firm investment decisions. Capital irreversibility is not postulated but endogenized using a quadratic adjustment cost function. Using this framework, we study the effects of environmental policies considering taxes on polluting inputs and subsidies to reduce the cost of abatement capital. Environmental policies promoted to enforce abatement capital may generate the unexpected result of reducing the abatement investment rate.     

China and India in the global economy

The purpose of this overview paper is to present the economic growth in China and India over the last three decades with a specific focus on the integration of these countries into the global economy. In the first part, we briefly review the long-run process of growth and institutional change, emphasizing the reforms leading to the “opening” of the two economies. Then, we focus on key structural features and compare the recent development processes of the two countries. At the end, there are some hints about certain persisting imbalances and the sustainability of the growth processes.
