This paper examines how policies regulating the cross‐border movement and domestic use of electronic data on the internet impact the productivity of firms in sectors relying on electronic data. In doing so, we collect regulatory information on a group of developed economies and create an index that measures the regulatory restrictiveness of each country's data policies. The index is based on observable policy measures that explicitly inhibit the cross‐border movement and domestic use of data. Using cross‐country firm‐level and industry‐level data, we analyse econometrically the extent to which these data regulations over time impact the productivity performance of downstream firms and industries, respectively. We show that stricter data policies have a negative and significant impact on the performance of downstream firms in sectors reliant on electronic data. This adverse effect is stronger for countries with strong technology networks, for servicified firms, and holds for several robustness checks.  相似文献

According to most classifications, Sub‐Saharan Africa is the region of the world with the highest presence of fragile states. In this paper we examine the relationship between fragility and poverty, suggesting that countries may become trapped in a vicious circle of fragility and low levels of wellbeing. We consider fragility as a continuum and begin by reviewing available measures. These show the high presence of fragility in Sub‐Saharan Africa and allow the more fragile countries to be identified. There is seen to be a strong association between fragility, poor growth performance, and lower wellbeing in Sub‐Saharan Africa. Building on the strong evidence for the two‐way relationship between economic growth and poverty, we present an analysis of how the vicious circle linking poorer welfare outcomes and fragility may be able to be broken. We argue that building successful institutions is key here, and this can be enabled by specific policy interventions that are both poverty reducing and productive.  相似文献

This paper investigates the existence of markups and their cyclical behaviour at the industry sector level. Markups are given as a price-cost relation that is estimated from a dynamic, structural model of the firm. The firms face costly adjustment of labour and potential financial constraints. The model is tested on a panel of firm- and plant-level data from Norwegian manufacturing industries. The results indicate a frequent presence of moderate pro-cyclical markups. Labour adjustment costs are present in four out of seven sectors but small in magnitude. The results are related to the role played by unions in a setting with high union density.  相似文献

A generalization is presented of the existence results for an optimal consumption problem of Aumann and Perles [4] and Cox and Huang [10]. In addition, we present a very general optimality principle. Received: July 14, 1999; revised version: September 9, 1999  相似文献

Environmental Innovations in Small and Medium Sized Enterprises   总被引:1,自引:0,他引:1  
Supporting and accelerating the adoption and diffusion of environmental innovations amongst small and medium sized enterprises (SMEs) is a major challenge to environmental policy makers. Research suggests that whilst SMEs possess high flexibility, their innovative capacity may be limited to incremental changes within their existing technology system and network. Twenty case studies examining the innovation adoption process in SMEs in four sectors and in five countries within the ENVIS project (commissioned by the EU) revealed great variety in factors driving this process. Findings indicate that this variation can be attributed to the character of the environmental innovation, the specific business opportunity, the regulatory setting and pressure experienced by the sector. Based on these findings an analytical framework is suggested, whereby the environmental innovative capability of SMEs is conceived as the result of an interplay between the competencies, the network relations and the strategic orientation of the company (the 'dynamic triangle'). This indicates that policy to support SME's adoption of environmental innovations has to take an integrated form, i.e. addressing and developing competence, networks and strategic orientation of SMEs simultaneously whilst remaining systemic and context sensitive.  相似文献

The market for publicly traded equity is the heart of a modern capitalist system. In particular, the market for newly listed firms is in turn a bellwether for the public equity market because the entry gives firms expanded access to capital, allowing them to emerge and grow. On the other hand, stock markets also serve as an institution to reallocate productive resources from non-surviving to surviving firms. We describe the Neuer Markt—a special segment of the Frankfurt Stock Exchange in Germany—as an institution to foster the creation of new firms and their destruction.
