An investigation of the black-box supplier integration in new product development

This research examines black-box supplier integration in new product development (NPD). A model and several hypotheses are proposed to study the relationship between product task characteristics (importance and complexity), supplier integration, and product performance. Data from 136 U.S. high-tech firms were used to test the hypotheses. Results suggest that assessing the importance and complexity of NPD tasks is critical to the implementation of supplier integration innovation strategy. Firms are likely to perform NPD tasks that are related to firms' core competencies in-house. They tend to externalize complex tasks to suppliers in order to utilize suppliers' resources and to increase NPD speed. The black-box supplier integration influences the speed to market. However, it is more effective on speed to market when technology uncertainty is low than when technology uncertainty is high.     

The Ancillary Benefits from Climate Policy in the United States

This study investigates the benefits to human health that would occur in the United States (US) due to reductions in local air pollutant emissions stemming from a federal policy to reduce greenhouse gas emissions. In order to measure the impacts of reduced emissions of local pollutants, this study considers the Warner-Lieberman bill (S.2191) of 2007 and the paper considers the impacts of reduced emissions in the transport and electric power sectors. This analysis provides strong evidence that climate change policy in the US will generate significant returns to society in excess of the benefits due to climate stabilization. The total health-related co-benefits associated with a representative climate policy over the years 2010–2030 range between 103 billion and103 billion and 1.2 trillion in present value terms. Much of the co-benefit stems from between 32,000 and 189,000 avoided premature mortalities associated with exposure to PM_2.5 and O₃. Most of the co-benefits are due to reduced emissions of SO₂ from coal-fired power plants since these are an important contribution to ambient concentrations of PM_2.5. Among the most important determinants of co-benefits is the relationship between climate policy and existing policies governing SO₂ discharges from coal-fired power generation capacity. If SO₂ emissions are permitted to remain at current levels, total co-benefits are cut by 65%. We find that the co-benefit per ton of CO₂ emissions ranges between 1 and1 and 77 depending on modeling assumptions and year.     

Organizational political climate: Shared perceptions about the building and use of power bases

Organizational politics continues to be acknowledged as a real and important dimension of organizational functioning. Most research has focused on ‘perceptions of organizational politics’ where organizational politics is conceptualized negatively and its relationship with detrimental individual and organizational outcomes is demonstrated. We argue that organizational politics can be conceptualized as a multi-dimensional climate level construct and that ‘organizational political climate’ can be both functional and dysfunctional. We propose and explain a four dimensional model of organizational political climate informed by existing theoretical perspectives on power bases. The four key dimensions are represented by the building and use of personal power, positional power, connection power and informational power. We also highlight the need for a comprehensive measure of organizational political climate which is underpinned by the four dimensions and which enables an assessment of the extent to which the organizational political climate is functional and/or dysfunctional. In summary, we recommend that HR practitioners seek to understand the functional and dysfunctional dimensions of organizational political climate and implement practices to foster a positive political climate. We overview practical implications for HR managers and suggest a future research agenda.     

Rallying the Troops or Beating the Horses? How Project‐Related Demands Can Lead to Either High‐Performance or Abusive Supervision

In today's high‐pressure work environment, project managers are often forced to “do more with less.” We argue that this imperative can lead project managers to engage in either high‐performance or abusive supervision behaviors. To understand this process, we develop a model and associated propositions linking a project manager's cognitive appraisal of project‐related demands to high‐performance work practices versus abusive supervision behaviors—both of which impact three project outcomes: stakeholder relationships, people‐related project success factors, and employee well‐being. We propose that the choice between high‐performance work practices and abusive supervision behaviors is moderated by a project manager's personal resources (psychological capital, emotional intelligence, and dark triad personality).     

Share portfolios in the early years of financial capitalism: London, 1690–1730

The dramatic expansion of public and private financial markets in the aftermath of the Glorious Revolution has received extensive attention. Despite this, little is known about how ordinary individual investors managed risk within this framework. Using a newly constructed dataset of share ownership for those joint‐stock companies listed in the financial press of the day, we reconstruct individual portfolio holdings for investors in these companies. We examine individual portfolio holdings first for the decade after the Glorious Revolution and then for the years around the South Sea Bubble. Despite a fivefold increase in the number of unique individuals in the market between the 1690s and the 1720s, we find that in each period roughly 80 per cent of those active in the equity market held shares in only one company, even though many shareholders had the capacity or wealth to diversify share portfolios. These outcomes suggest diversification against idiosyncratic liquidity risk. Overall, however, there is limited evidence that individuals were using their financial portfolios to protect against diversifiable shocks. For many, we argue, company‐specific voting and firm governance rules drove market activity.     

Land use and income diversification: comparing traditional and colonist populations in the Brazilian Amazon

This article compares and analyzes land use and income diversification among two distinct groups of farmers in the Brazilian Amazon: recent colonists in Ouro Preto do Oeste, Rondônia, and traditional long‐term residents along the Tapajós River, Pará. We investigate the hypothesis that farmers who diversify their cash income sources clear less forest on an annual basis, and we compare these livelihood choices across colonist and traditional populations. In particular, we develop a conceptual model based on the household production framework and use econometric models to identify determinants of diversification and forest clearing. We find that diversification of agricultural cash crops is negatively correlated with forest clearing by colonists, providing limited evidence for the hypothesis. Other significant covariates of diversification and forest clearing include cash income levels, stage in family life cycle, cattle ownership, and chemical inputs. Differences in these variables, and differences in household response to these variables, explain variation in diversification and forest clearing across the two populations.     

Acquisition,affinity and rewards: Do they stay or do they go?

Customer relationship management seeks to understand how to generate profitable customers who enter into a long-term relationship with a firm. In this paper, we examine the role of modes of acquisition and retention programmes on customer lifetime in the context of a credit card issuing bank. While other papers have studied retention programmes such as loyalty card and reward card, there is no published study in the credit card context. Using a rich data set on nearly 5,000 customers observed over a three-year period, we are able to provide detailed insights about the efficacy of these strategies. We show that affinity cards customers and customers acquired through direct mail have longer lifetimes. We also find that reward card programmes generate customers with a shorter lifetime. Finally we re-examine the link between long-life customers and profitability and find that the relationship is weak, consistent with recent findings.     

On Structural Sources of the 1994 Turkish Crisis: a CGE modelling analysis

This paper investigates the impact of the Turkish public sector imbalances on the evolution of the economic crisis during 1990–93. A computable general equilibrium model is used. The theoretical basis of the model rests upon the structuralist/Keynesian macro foundations. Its distinguishing features entail accommodation of oligopolistic mark-up pricing rules in the industrial sectors, and endogenous solution of capacity utilisation and unemployment levels through Keynesian mechanisms of effective final demand. The results of the model underscore the importance of intra-class relations of income distribution and conflict in the evolution of price movements in the Turkish economy. It is further argued that the sources of the capitalist in the administrative interventions of the state towards protection of the capitalist and rural incomes, which would otherwise be squeezed out in favour of wage-labour in the early 1990s.
