This paper focuses on the process of Computer Aided Design (CAD) diffusion into a group engaged in the development of innovative products. Adopting an ethnographic approach, we build a grounded theory for interpreting CAD usage in terms of the interplay between variables such as management orientation, training, actors' specialisation and deskilling, availability of shared archives, technological discontinuities between organisational areas. 相似文献

ABSTRACT In this paper we provide a proof of the ‘Granger representation theorem’ starting from Phillips' triangular representation of a cointegrated system. Proofs of the theorem have already been provided but starting either from the MA representation or from the AR representation. Conversely, we derive and characterize analytically the MA and the AR representations in terms of the parameters of the triangular system. 相似文献

The authors investigate the differences in margins of export and domestic markets for Spanish manufacturing firms in the period 1990 to 1997. They estimate jointly a multiproduct cost function, a variable factor share equation, and two price/marginal‐cost margin equations. The results indicate that the marginal cost of production sold in export markets is slightly greater than in domestic markets. At the same time, the price/marginal‐cost margins in export markets are smaller than in domestic markets. There is also strong evidence that margins are procyclical in domestic markets, but this evidence is less clear in foreign markets. 相似文献

The performance of Latin American countries in reducing poverty and expanding the middle class has been remarkable. By taking a close look at the Peruvian experience, we examine how this aggregate behavior relates to business cycle conditions and whether different population groups share this behavior. We find that social mobility is cyclical; it decreases in recessions but increases with strong economic growth. The reduction in poverty in Peru appears to be the result of a sustained increase in the poverty exit rate together with a prolonged decrease in the poverty entry rate. These results hold among heterogeneous groups and are particularly marked for households regarded as initially disadvantaged. 相似文献

We document the substantial process of structural transformation—the reallocation of labor between agriculture, manufacturing,
and services—and aggregate productivity growth undergone by Portugal between 1956 and 1995. We assess the quantitative role
of sectoral labor productivity in accounting for these processes. We calibrate a model of the structural transformation to
data for the United States and use the model to gain insight into the factors driving the structural transformation and aggregate
productivity growth in Portugal. The model implies that Portugal features low and roughly constant relative productivity in
agriculture and services (around 22%) and a modest but growing relative productivity in manufacturing (from 44 to 110%). We
find that productivity growth in manufacturing accounts for most of the reduction of the aggregate productivity gap with the
United States and that a further closing of this gap can only be accomplished via improvements in the relative productivity
of services.

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification. 相似文献

We introduce a simple model of oligopolistic competition where firms first build capacity, and then, after observing the capacity decisions, choose a reservation price at which they are willing to supply their capacities. This model describes many markets more realistically than the model of Kreps and Scheinkman [Kreps, D., Scheinkman, J., 1983. Quantity precommitment and Bertrand competition yield Cournot outcomes. Bell J. Econ. 14, 326–337]. We show that in this new model every pure strategy equilibrium yields the Cournot outcome, and that the Cournot outcome can be sustained by a pure strategy subgame perfect equilibrium. 相似文献

We examine the performance of 160 pharmaceutical acquisitions from 1994 to 2001 and find evidence that on average acquirers realize significant positive returns. These returns are positively correlated with prior acquirer access to information about the research and development activities at target firms and a superior negotiating position. A unique Desperation Index is employed to determine the current status of a firm's internal productivity. We find that firms experiencing declines in internal productivity or which are more desperate are more likely to engage in an outsourcing-type acquisition in an effort to replenish their research pipelines. 相似文献

Although sustainable development is increasingly becoming a part of business plans, it is unclear what makes the economic, social and environmental dynamics strategically compatible. This research examines which of the following in sustainable development – government policy, managerial attitude and stakeholder engagement – is the most influential on the profitability of companies in the UK construction sector. Quantitative and qualitative analyses were rendered through a survey and semi‐structured interviews. Patterns of ambiguity in legislation were discovered as an obstacle for changing the sector's mind‐set. Stakeholder engagement was identified as the defining factor increasing managers' awareness, helping legislation to be effectively implemented and making sustainability highly appealing to clients. These findings indicate that to gain competitive advantage, companies should embark on long‐term strategic alliances which adopt the proposals of environmental non‐governmental organisations and closely follow public opinion. This, strengthens brand equity, allows for premium pricing, increases market share and maximizes profit. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment. 相似文献

This article contributes to the current literature on mergers and acquisitions (M&As) by identifying the existence of waves and the determinants of M&A activity in the economies of Argentina, Brazil, Chile, Colombia, Mexico, and Peru. From a sample of 2,391 M&A announcements reported by Thomson One on these countries, applying the methodology proposed by Harford (2005), evidence of M&A waves is found for the periods 1995–2002 and 2003–2010, as reported for other regions in various international studies. After controlling for economic and business environment variables, as well as for profitability and book-to-market variables at the industry level, we find evidence that supports neoclassical theory as a main explanation for M&A activity but not for the misvaluation effect. 相似文献
