This paper empirically investigates the development of cross-country differences in energy- and labour productivity. The analysis
is performed at a detailed sectoral level for 14 OECD countries, covering the period 1970–1997. A σ-convergence analysis reveals
that the development over time of the cross-country variation in productivity performance differs across sectors as well as
across different levels of aggregation. Both patterns of convergence as well as divergence are found. Cross-country variation
of productivity levels is typically larger for energy than for labour. A β-convergence analysis provides support for the hypothesis
that in most sectors lagging countries tend to catch up with technological leaders, in particular in terms of energy productivity.
Moreover, the results show that convergence is conditional, meaning that productivity levels converge to country-specific
steady states. Energy prices and wages are shown to positively affect energy- and labour-productivity growth, respectively.
We also find evidence for the importance of economies of scale, whereas the investment share, openness and specialization
play only a modest role in explaining cross-country variation in energy- and labour-productivity growth.

An important role of managers is to motivate subordinates. Monetaryrewards have been the focus of economic analysis. Managers alsouse other means to influence subordinates. If a manager canbetter assess the subordinate's ability than the subordinatehimself, and if ability and effort are complements, the managerfinds it hard not to overstate a junior's ability. Talk is cheap.We analyze under what conditions a manager can use organizationalpractices such as delegation and the selective provision ofattention to credibly communicate his assessment. We comparetheir desirability. Delegation is preferable in case the manager'sassessment is fairly accurate; attention is inescapable if itis inaccurate. 相似文献

Analysts in a bank’s research department cover firms that have no relationship with the bank as well as companies in which
the bank has a strategic interest. Officially, banks must establish Chinese Walls around their research departments to allow
the analysts to work independently and to avoid the flow of insider information. We examine analyst behavior under long-term
bank-firm relationships using ownership data and analysts’ earnings per share forecasts for German companies from 1994 to
2001. We find evidence that is consistent with analysts reconciling their employers’ interests with their own career concerns.
They seem to use their information advantage strategically by releasing favorable and thereby more precise reports when the
market underestimates earnings. In order not to jeopardize the bank-client relationship, they suppress negative information
when the market is too optimistic. Combining situations where the market over- and underestimates earnings, we can replicate
the unconditional positive bias in analyst forecasts found in the previous literature. Despite the bias in affiliated analysts’
forecasts, they nonetheless selectively communicate valuable information to investors.

Organizational culture and performance measurement systems 总被引:3,自引:0,他引:3

The aim of this study is to articulate and test the relationships between organizational culture and two attributes of performance measurement systems (PMS), namely the diversity of measurement and the nature of use. The results of a survey reveal that top managers of firms reflecting a flexibility dominant type tend to use more performance measures and to use PMS to focus organizational attention, support strategic decision-making and legitimate actions to a greater extent than top managers of firms reflecting a control dominant type. 相似文献

This paper investigates how welfare losses for facing high-order risk increases change when the risk environment of the decision maker is altered. To that aim, we define the nth-order utility premium as a measure of pain associated with facing the passage of one risk to a more severe one and we examine some of its properties. Changes in risk are expressed through the concept of stochastic dominance of order n. The paper investigates more particularly welfare changes of merging increases in risk, first ignoring background risks, then taking them into account. Merging increases in risk may be beneficial or not, depending on whether background risks are considered and how. The paper also provides conditions on individual preferences for superadditivity of the nth-order utility premium. The results confirm the importance and usefulness of two analytical concepts: mixed risk aversion and risk apportionment. 相似文献

How responsive are migrant remittances to various disasters, both natural and human-made? Would remittances be affected by systemic financial crises, such as the 2008–09 financial crisis, or more recent crises affecting the Eurozone? Using panel data on 23 sub-Saharan African (SSA) countries from 1980 to 2007, we find that remittances are slow to respond to natural disasters, unresponsive to outbreaks of conflict, and will slowly decline following a systemic financial crisis. This suggests that, given its stability, remittances are sources of resilience in SSA. 相似文献

In this paper, we argue that conceptually disentangling the ‘context versus composition’ aspects of regional growth is a multilevel issue. By applying multilevel models (also called random-effects models), we show (1) the importance of considering firm-specific characteristics simultaneously with region-specific characteristics, as we find that a large part of what is traditionally assigned to the impact of the region should be assigned to firm-specific characteristics and (2) that existing single-level methodologies can be problematic, as they are vulnerable to the charge of estimating significance levels that are too liberally assigned and promote exaggerations. This is illustrated empirically by showing that single-level approaches would lead to the conclusion that innovation spillovers are highly significant in a setting of Dutch urban growth differentials, while multilevel analyses shows less liberally assigned significance levels. We conclude that multilevel-effect models better fit research questions that combine firm and spatial characteristics simultaneously, especially because they allow firm-specific characteristics to be differently linked to their regional contexts. 相似文献

In contemporary African cities, dressing well and wearing exclusive garments has become crucial for people in search of identity, distinction and individuality. The research presented in this article, situated at disciplinary intersections of cultural studies, fashion practices and sustainability, provides a case study of African tailors conducted in Maputo and Lisbon, with a special focus on identity building of African immigrants in Portugal. However, the role of tailors in this acculturation process has been ignored in the consumption approach to creative cities. This study is therefore also a reaction to the mainly Western world of regular couture, and to ‘creative city materials’ that focus on consumption. Instead, we emphasize the importance of African tailors who de facto shape urban experiences—visually incrementing practices—that are fundamental to the comprehension of sartorial culture, while we also allude to the complex intersections between local and global markets. In the first part of this article we describe a semi-ethnographic study among tailors in Maputo and Lisbon. The second part presents a participatory action approach that entailed developing an educational programme for African tailors where culture and creativity meet. This programme empowered tailors to tap into their cultural knowledge on tailoring and their awareness of community identity. In our study we argue that the idea of creative cities and their creative economy should be approached from a cultural perspective, by building awareness of the importance of local creative classes instead of focusing on importing those classes. 相似文献
