The Relationship between Delegation and Incentives Across Occupations: Evidence and Theory

A large literature suggests that incentive pay and delegation of worker authority are positively related. Using data from a large cross section of British establishments, we show that the positive relationship found in the empirical literature masks a stark difference across jobs. Classifying jobs into two categories (complex jobs, including professional, technical and scientific occupations, and simple jobs, consisting of all other non‐managerial occupations) we find a positive relationship for simple jobs and a negative relationship for complex jobs. To explain this negative relationship, we develop a model where stronger incentives distort a worker's decisions towards low risk‐return tasks. 相似文献

This paper discusses the nature of the 10 example paragraph entries at the end of Pacioli's bookkeeping treatise. It concludes that these are entries from fledgling banking operations involving one account holder and one borrower who, along with two others, has financial transactions with the account holder. The widely held assumption that they are examples of entries in the Ledger is set aside and it is concluded that, on the basis of the available evidence, they are examples of entries in a Ricordanze, a record book Pacioli described as being used to record items of this type. 相似文献

The way firms lengthen or shorten their product line with respect to rivals is regarded as one of the possible strategies firms can pursue to respond to competition. This article builds and tests hypotheses to study the effect of different levels of competitive intensity on product line length. The empirical analysis of data on 3,527 handset models introduced by 66 mobile phone vendors from 1994 to 2010 shows a consistent inverse U‐shaped relationship between competitive intensity and the firm's product line length. In this way, we pinpoint an interesting link between the product line extension literature and the competitive dynamics and competitive intensity perspectives.

We show that the composition of international trade has important implications for the optimal volatility of the exchange rate, above and beyond the size of trade flows. Using an analytically tractable small open economy model, we characterize the impact of the trade composition on the policy trade-off and on the role played by the exchange rate in correcting for price misalignments. Contrary to models where openness can be summarized by the degree of home bias, we find that openness can be a poor proxy of the welfare impact of alternative monetary policies. Using input–output data for 25 countries we document substantial differences in the import and non-tradable content of final demand components, and in the role played by imported inputs in domestic production. The estimates are used in a richer small-open-economy DSGE model to quantify the loss from an exchange rate peg relative to the Ramsey policy conditional on the composition of imports. We find that the main determinant of the losses is the share of non-traded goods in final demand. 相似文献

The Contribution of Bioenergy to a New Energy Paradigm 总被引:1,自引:0,他引:1
Biomass is a widely available resource that is receiving increased consideration as a renewable substitute for fossil fuels. Developed sustainably and used efficiently, it can induce growth in developing countries, reduce oil demand, and address environmental problems. The potential benefits include: reduction of greenhouse gases, recuperation of soil productivity and degraded land, economic benefits from adding value to agricultural activities and improving access to and quality of energy services. The production of bioenergy involves a range of technologies, including solid combustion, gasification, and fermentation. These technologies produce energy from a diverse set of biological resources - traditional crops, crop residues, energy-dedicated crops, dung, and the organic component of urban waste. The results are bioenergy products that provide multiple energy services: cooking fuel, heat, electricity and transportation fuels. It is this very diversity that holds the potential of a win-win-win for the environment, social and economic development. Bioenergy has to be viewed not as a replacement for oil, but as an element of a portfolio of renewable sources of energy. Coherent and mutually supportive environmental and economic policies may be needed to encourage the emergence of a globally dispersed bioenergy industry that will pursue a path of sustainable development. 相似文献

We implement a controlled, multi-site experiment to develop and test guidance principles for benefits transfers. These argue that when transferring across relatively similar sites, simple mean value transfers are to be preferred but that when sites are relatively dissimilar then value function transfers will yield lower errors. The paper also provides guidance on the appropriate specification of transferable value functions arguing that these should be developed from theoretical rather than ad-hoc statistical approaches. These principles are tested via a common format valuation study of water quality improvements across five countries. While this provides an idealised tested, results support the above principles and suggest directions for future transfer studies. 相似文献

The study of one's own business future is a distinctive element of a business strategy. Innovative companies are aware of weak signals coming from the periphery and of trends in their industry, and they monitor the coherence between weak signals and trends (the external perspective) and strategic direction (the internal perspective).The literature today does not provide well-framed and complete methodologies for assessing the coherence among trends, vision and products. Therefore, the authors propose a methodology called “the methodology of future coverage”, which measures how much the strategy oriented to the future effectively covers trends and megatrends. In other words, it helps to check the contents and the coherence of the firm' vision and products and those of the trends that will have relevance for the future of the industry, and this process supplies firms with supplementary information on how to improve. The authors tested this methodology and exemplified its use via the Eurotech case study, employing longitudinal analysis.The methodology can be useful as a tool for diagnosing the coherence between trends and company strategy. Moreover, from a dynamic point of view, it can be used as a tool to check on the company's progress in following up on trends by adapting its strategy over time. Finally, the methodology can be also used as a tool for cross-comparison of the “level of future orientation” among companies in the same industry. 相似文献

This paper examines the impact of projected demographic trends on international capital flows. The analysis builds upon a ten-region overlapping generations' model of the world economy where capital is mobile across regions. Results show that, over the first half of the century, emerging regions will finance the demand of capital coming from the developed world where population aging is relatively advanced. In particular, the findings suggest that in the coming decades China will be the world's main creditor region. However, in the second half of the century, India will take over this leading position because of the predicted decline in the Chinese labor force. An additional analysis demonstrates that the economic consequences of demographic changes depend on the degree of capital market integration between regions. 相似文献
