The economics of information allows one to distinguish within the national product the real production from the costs of organization. It reveals a continuous inflation of these costs which, per employee and since 1900, has been twice as fast as the increase of productivity. From this, one can conclude that the growth of productivity comes up against a real ‘wall’ when the costs of organization approach 50% of the national product. This is the essential cause of the present crisis. The author subsequently designs an economy of organization structures applicable to complex systems, such as physical, biological or social systems. He shows how the 50% wall is characteristic for centralized structures. Most economic structures are those where social forces and solidarities are distributed justly among all levels of organization, from local to global ones. They tend to establish themselves by self-organization, but a new political economy applying these principles would, aided by information and communication technologies, accelerate this process.  相似文献

In some of their papers published in the 1950s, Herbert Simonand Sidney Siegel responded to the so-called mixed strategyanomaly in ways which deserve more attention. They producednot only (i) immediate defences of the economic theory of theirown time, but also (ii) ideas and solutions that have laterturned out to be significant contributions to the developmentof the economic theory of choice and decision-making and theseparation of experimental economics from experimental psychology.These observations suggest that economics can be more responsiveto empirical anomalies than has been assumed. Furthermore, knowledgeof the desirable responsiveness to anomalies can provide meansof avoiding the non-desirable immunity to anomalies.  相似文献

Frequent climate shocks require farmers in developing countries to increase their resilience. Although index insurance is often discussed as a promising climate adaptation strategy, take-up rates are still low. This study primarily explores the role of peer behavior as peer imitation in the demand for three marketable and unsubsidized crop index insurance options. Furthermore, the influence of trust and understanding is investigated. We collected data in lab-in-the-field experiments among farmers in Kyrgyzstan, where index insurance is planned for imminent implementation. Applying ordered logit estimations, our results show significant and strong peer imitation effects. Imitation attitudes decrease with own insurance experience and received insurance payouts, but intensify with peer size, insurance trust and practical insurance understanding. While trust robustly increases index insurance adoption, understanding effects only gain significance in the dynamic perspective. These findings underline the importance of community-based extension treatments and trust toward the uptake of innovative agricultural technologies in the first steps of dissemination.  相似文献

This article proposes a conceptual and theoretical institutional approach to the relations between the economy and economics and uses it to examine, through a structured survey of the literature, the relations between institutions in the economy and the institutions of mainstream economics, macroeconomics, and financial economics, highlighting issues related to the financial and macroeconomic crisis and focusing on the United States from the late 1970s to 2008. Institutions are socially shared systems of rules of behavior or of thought. Some systems of mental and behavioral rules are socially shared among economic agents and policymakers in part because they are socially shared among academic economists. They may exert on economic agents and policymakers some of the same types of influence they have on economists. On the other hand, there are important limits to the influence of the institutions of economics outside academia, and institutions in the economy also influence the institutions of economics.  相似文献

A new multi-logistic methodology to analyze long range time series of evolutionary S-shaped processes is presented. It conceptually innovates over the traditional logistic approach. The ansatz includes computing the residuals to an optimized multi-logistic trend curve least squares fitted to the time-series data. The elements of the residuals series are checked for autocorrelations and once detected the residuals series is further analyzed to search for eventual presence of underlying periodic structures using a truncated Fourier sine series. The method foundations ensures both a universal applicability and a capacity to disclose the existence of active clocks that can be possibly traced to the driving motors of the evolutionary character of the time series, due to the responsiveness of corresponding process to the development of economic cycles. On associating these two views, it is found that the methodology has a strong potential to improve the quality of short-term forecasts. These findings have been put to test through applications of the methodology to studying the time evolution of two commodities of strong economic and social importance (corn and steel) and good results were consistently obtained for both the analytical and forecasting aspects.  相似文献

This paper evaluates the impact of Brazil's National Program to Strengthen Family Farming (PRONAF) on the time allocation of household members. We use data from the 2014 Pesquisa Nacional por Amostra de Domicílios, and we apply propensity score methods to complex surveys recently recommended in the literature. We find that PRONAF helps to increase focus on agricultural activities, but it also stimulates female partners to engage in unpaid work. The results show significant effects of PRONAF on child labor and on the gender‐specific division of labor within households, although it does not have the usual adverse effects of rural credit programs on school attendance.  相似文献

We develop a general and unifying methodology for ecological economics which integrates philosophical considerations on the foundations of ecological economics with an adequate operationalization. We argue that the subject matter and aims of ecological economics require a specific combination of inter- and transdisciplinary research, and discuss the epistemological position on which this methodology is based. In accordance with this understanding of inter- and transdisciplinarity and the underlying epistemological position, we develop an operationalization which comprises simultaneous analysis on three levels of abstraction: concepts, (generic) models and case studies. This provides a systematic and integral view on ecological economics, and thus allows one to see the relationship between contributions to the field that have so far been perceived as very heterogeneous and largely unrelated. At the same time, this methodological framework may provide orientation for the further development of ecological economics.  相似文献

Worldwide, improved sources of drinking water are still lacking for 663 million people. With Malawi as a case study, we aim to address the scarcity of data available to understand the full cost and options of drinking water at a regional level covering both urban and rural areas. We studied options in the northern region of Malawi under the following thematic areas: urban piped water, water wells, handpump spare part supply networks, household point-of-use water treatment, the cost of entering a water business and capacity building in science education. Primary locally sourced data were collected as well as secondary publically available data. Additionally, local markets were surveyed for spare part networks. This research has shown that when looking at water resource economics in northern Malawi, it is not a monopoly and options are available at a range of costs. The data challenge policy-makers to reach the last 10% of the population still lacking improved drinking water. This will require a combination of expansion of urban piped water infrastructure, new boreholes in rural areas, increased handpump functionality rates, scale-up of household drinking water point-of-use treatment and growth of local universities to train local experts within the sector.  相似文献

Gualerzi's comment on Trezzini’s 2015 article (‘Growth without Normal Capacity Utilization and the Meaning of the Long-Run Saving Ratio.’) underestimates the role played by the long-run elasticity of output with respect to changes in aggregate demand in my analysis and in the demand-led processes of growth.  相似文献

Like their Greek counterparts, a number of Chinese thinkers of the “Axial Period” wrote extensively on the division of labour. In particular, Kuan Chung, Hsün Tzu and Ssu-ma Ch’ien explicitly discussed economic issues related to the division of labour, contributing sophisticated analysis on the subject. In this article, we first examine Kuan Chung and his followers’ fairly interesting analysis of the economies of agglomeration of specialists, and Ssu-ma Ch’ien's deep insight into the Taoist invisible hand of the market in coordinating the division of labour. The common ground between them is a sound understanding of the role of market exchange in facilitating the social division of labour, but the latter goes much further in appreciation of the spontaneous market order. We then turn to Hsün Tzu's profound scholarship of specialised learning or doing and his Confucian theory of the origin of social division, highlighting, in particular, his Confucian notion of natural equality and utilitarian account of the formation of society. Similarity in profundity and influence notwithstanding, of greater interest, appears to be the remarkable differences between the Chinese scholars and the philosophers of classical Athens in respect of their study of the division of labour, and we therefore investigate how and why the Chinese treatment contrasts thus sharply with the Greek/Europeans.  相似文献

The purpose of this paper is to explain the sources of energy system lock-in. It presents a comparative analysis of the respective contributions of some features of increasing returns to adoption factors, i.e. learning-by-doing, learning-by-searching and returns to scale effects in explaining the technological change dynamics in the energy system. The paper is technically based on a critical analysis of the learning curve approach. Econometric estimation of learning and scale effects inherent to seven energy technologies were performed by the use of several learning curve specifications. These specifications permit to deal with some crucial issues related to the learning curve estimation which are associated with the problem of omitted variable bias, the endogeneity effects and the choice of learning indicators. Results show that dynamic economies from learning effects coupled with static economies from scale effects are responsible for the lock-in phenomena of the energy system. They also show that the magnitude of such effects is correlated with the technology life cycle (maturity). In particular, results point out that, 1) the emerging technologies exhibit low learning rates associated with diseconomies of scale which are argued to be symptomatic of the outset of the deployment of new technologies characterized by diffusion barriers and high level of uncertainty, 2) the evolving technologies present rather high learning rates meaning that they respond quickly to capacity expansion and R&D activities development, 3) conventional mature technologies display low learning rates but increasing returns to scale implying that they are characterized by a limited additional diffusion prospects.  相似文献

Abstract

Sraffa's book artfully combines an exposition of key problems of capital theory, using economic logic, with mathematical arguments, and he created a school of disciples extending his ideas by means of both methods. His analysis of single product systems has turned out essentially to be flawless, but the problems of joint production cannot simply be solved on the basis of analogies with single production. A truncation approach and a dynamic approach are discussed in order to summarise his main results, to illustrate his method and to take stock of the recent developments of the theory.  相似文献

The more that health care expenditures are financed by general taxation, the greater the discretion governments are likely to exercise when timing increases in health care expenditures. Vote-maximising governments time increases in health care expenditures to occur in economic upturns, when voters are not as aware of the required increase in taxation. In recessions, they have an incentive to sustain expenditures on health care by diverting expenditures from other public expenditure programmes that voters perceive as low priority. In this way, government pursuit of a political agenda is likely to exert a systematic influence on the cyclicality of government expenditure. Predictions are tested with reference to the cyclicality of government health expenditures, for a sample of OECD countries from 2000 to 2012.  相似文献

This paper investigates the determinants of European Union FDI in the CEECs at sectoral level. The aim is to understand whether and to what extent FDI undertaken in different sectors reacts to the characteristics of the host countries. The analysis is based on a dataset created specifically for this purpose. It concentrates on the manufacturing sectors, classified according to the Pavitt taxonomy. Firstly, data summarizing the recent trend of FDI in the CEECs is presented and then empirical evidence given to account for differences between sectors. The estimated model is a generalization of a three-way fixed effect model incorporating 'classic' variables, such as labour costs as well as country-specific variables, i.e., the stage reached in the transition process. The results confirm the presence of heterogeneity at sector level.  相似文献

社会观念、社会风气的转变是社会变迁的一个重要方面。清末民初安徽传统的"重义理,轻艺事"观念、"重农轻商""重儒轻商"观念的动摇,男女平等观念开始出现端倪,旧的生活方式和政治生活方式的些许变化及读新书、阅报刊、学外语、出国留学等新风气的出现,表明清末民初安徽传统的社会观念、社会风气在一定程度上、一定范围内有了异于传统的变化。这些变化,既是外力冲击的结果,也是安徽自身为适应时代的变化而不断自我调整的结果。但这些变化主要是发生在城市、城镇及社会上层,广大农村及社会下层的观念、风气还是较为保守的,对安徽社会来说,要使变化从点发展到面,从上延伸到下,还需要一段路程要走。  相似文献

This paper compares the importance of English proficiency (EP) on earnings among the foreign-born immigrants from 1980 to 2000 and shows its importance varied over time. The key issue examined is changes in the impact of being in a minority-language enclave and its interactions with the return to EP. Results show that the negative effects of enclaves were the greatest in 1990 and such effects were significantly stronger among those fluent English speakers. The relationship between EP and the enclave effects is explored, which confirms their strong interaction in 1990. However, the evidence of fluent speakers' large migrations from enclaves between 1990 and 2000 is not strong, as of the 24 foreign language groups, 13 showed decreases in fluency in enclaves relative to non-enclaves, while 11 showed increases in fluency in enclaves relative to non-enclaves. This may relate to non-wage benefits of living in enclaves, such as social benefits.  相似文献

This paper analyzes the question whether web applications pose a disruptive threat to incumbents or a disruptive growth opportunity for entrants in the application software industry using a novel method for ex ante identification of disruptive innovations in the software industry. Building on the theory of disruptive innovations, network effects and existing frameworks for the ex ante identification of disruptive innovations a new method of analysis is deduced. The analysis is based on a list of criteria that indicate a disruptive innovation and trajectory maps of the technologies' performance attributes. This method is applied to study the potential disruption of Microsoft's desktop office applications by Google's web-based office applications.The chosen method of analysis indicates a small likelihood for web applications to pose a disruptive threat to Microsoft, and by extension, to incumbents in the software industry. While web applications show a potential to satisfy market demand in established performance attributes, strong network effects in existing software products should give incumbents enough time to co-opt the innovation. The case illustrates how our new method to analyze disruptive potential in the software industry ex ante can help to apply the theory of disruptive innovation better for forecasting purposes and to provide novel strategic insights for the players involved.  相似文献
