The present work aims at contributing to the recent stream of literature which attempts to link the Neo-Schumpeterian/Evolutionary and the Post-Keynesian theory. The paper adopts the Post-Keynesian Stock Flow Consistent modeling approach to analyze the process of development triggered by the emergence of a new-innovative productive sector into the economic system. The model depicts a multi-sectorial economy composed of consumption and capital goods industries, a banking sector and two households sectors: capitalists and wage earners. Furthermore, it provides an explicit representation of the stock market. In line with the Schumpeterian tradition, our work highlights the cyclical nature of the development process and stresses the relevance of the finance-innovation nexus, analyzing the feed-back effects between the real and financial sides of the economic system. In this way we aim at setting the basis of a comprehensive and coherent framework to study the relationship between technological change, demand and finance along the structural change process triggered by technological innovation.  相似文献

A research agenda for improving national Ecological Footprint accounts   总被引:3,自引:0,他引:3  
Nation-level Ecological Footprint accounts are currently produced for more than 150 nations, with multiple calculations available for some nations. The data sets that result from these national assessments typically serve as the basis for Footprint calculations at smaller scales, including those for regions, cities, businesses, and individuals. Global Footprint Network's National Footprint Accounts, supported and used by more than 70 major organizations worldwide, contain the most widely used national accounting methodology today. The National Footprint Accounts calculations are undergoing continuous improvement as better data becomes available and new methodologies are developed. In this paper, a community of active Ecological Footprint practitioners and users propose key research priorities for improving national Ecological Footprint accounting. For each of the proposed improvements, we briefly review relevant literature, summarize the current state of debate, and suggest approaches for further development. The research agenda will serve as a reference for a large scale, international research program devoted to furthering the development of national Ecological Footprint accounting methodology.  相似文献

Trade policy literature has for many years emphasized open policies positive impact on economic growth and development. While these results generally hold when measured on averages, empirical evidence suggests that trade liberalization is unlikely to produce beneficial results across all households. This study adds to the literature by providing an analysis of the distributive effects of tariff liberalization in Mexico. The paper examines the effect of tariff liberalization from the perspective of households both as consumers and factor owners allowing for imperfect domestic price transmission. The results indicate the overall positive effect of tariff liberalization masks significant differences in the distribution of gains both across income levels and across geographic regions. Richer households are found to have gained relatively more. Urban areas, as well as Mexican states closest to the United States border, are also found to be larger beneficiaries while southernmost states have been largely bypassed by the effects of tariff liberalization. Those results can be explained not only in relation to the different endowments of the households, but also by the diverse effects on local prices that has resulted from Mexican trade liberalization.  相似文献

We study the optimal dynamic portfolio exposure to predictable default risk, taking inspiration from the search for yield by means of defaultable assets observed before the 2007–2008 crisis and in its aftermath. Under no arbitrage, default risk is compensated by an ‘yield pickup’ that can strongly attract aggressive investors via an investment-horizon effect in their optimal non-myopic portfolios. We show it by stating the optimal dynamic portfolio problem of Kim and Omberg (Rev Financ Stud 9:141–161, 1996) for a defaultable risky asset and by rigorously proving the existence of nirvana-type solutions. We achieve such a contribution to the portfolio optimization literature by means of a careful, closed-form-yielding adaptation to our defaultable asset setting of the general convex duality approach of Kramkov and Schachermayer (Ann Appl Probab 9(3):904–950, 1999; Ann Appl Probab 13(4):1504–1516, 2003).  相似文献

ABSTRACT

Information accuracy and decision-making speed are of paramount importance in managing today’s mobility of goods and people inside the city. Intelligent Transport Systems (ITS) can provide road users with updated information and forecasts on both traffic and weather conditions. The result is a higher efficiency in the use of resources and a better management of physical flows. The purpose of this paper is to conduct an in-depth review on the role of ITS supporting urban Smart Mobility, in order to identify the main gaps in the literature and propose future research streams. In total, 71 papers have been thoroughly analysed: they are mainly focused on technology, with limited attention to value creation. Even though some benefits have been examined, a general lack of quantitative models emerged. Eventually, there is a lack of contributions considering both people and freight transport, even if they are strongly related, especially in an urban environment.  相似文献

After briefly recalling Sraffa's own contribution, the article surveys the ensuing debate, concerning both the critique of the marignalist theory, the revival of the classical approach, and the analytical contributions on specific aspects of Sraffa's 1960 book. Three lines of research for a modern reconstruction of th classical approach are then illustrated: Pasinetti's lsquo;Ricardianrsquo; reconstruction, Garegnani's lsquo;Marxianrsquo; reconstruction, and Sylos Labini's lsquo;Smithianrsquo; reconstruction. Finally, an assessment of these three research lines is provided, together with some suggestion for their integration.  相似文献

Assessing the level of development of small business in Russia requires a critical analysis of official statistics, owing to the existence of several inconsistencies. In addition, the frequent changes in the methodology make it difficult to compare the data over a period. It must also be taken into account that Russian and Western official data on small business are not fully comparable, as the Russian definition of small business has several limitations. For this reason its contribution to the economy is understated. Officially, employment in small businesses has stopped growing since 1994. Survey‐based results, however, point to a continuous increase in the number of people employed by new private enterprises, suggesting that the emergence of entrepreneurship has been an organic process, as in the leading transition countries, although it has been much slower in Russia.  相似文献

It is generally acknowledged that the cuts in government funding for research implemented in several European countries will induce academic researchers to increase their interaction with non academic entities to promote the acquisition of external funding for research. Indirectly this implies that there will be a shift in the focus of academic scientific activity from basic to applied research via private research contracts and consultancy work. The aim of our paper is to assess the extent of the trade-off between basic research and applied activity in academic research departments. We use data for the universe of Italian academic departments over the period 2006–2011 and estimate whether increased applied activity is substituting or complementing basic research activity. We provide empirical evidence of a strong substitution effect for life sciences departments and, to a lesser extent, for engineering and technology departments, while there does not seem to be evidence of a substitution effect for departments whose scientific activity revolves around basic science.  相似文献

Recent economic and organisational changes have fostered an increasing diversification of the workforce, among whom freelancers are an under‐represented population in the literature. This study aimed at examining the role of protean and boundaryless career, professional commitment, and employability activities in fostering freelancers' subjective career success. Data were collected via an online survey among a sample of 425 Italian freelancers and analysed through structural equation modelling. Results partially confirmed several hypotheses: higher self‐directed career management and boundaryless mindset predicted higher employability activities and professional commitment; moreover, employability and professional commitment acted as mediators between career attitudes and subjective career success. The study provides support for the importance of such variables to freelancers' career success, as well as for the significance of protean and boundaryless careers among nontraditional occupational groups. Interventions aimed at fostering such attitudes could support freelancers in improving their attainment of professional progress and perception of career success.  相似文献

The focus of this paper is on Lithuania, whose government released an ambitious innovation strategy to become an innovative services hub for Northern Europe by 2015, and an innovation hub by 2020. Biotechnology has been identified as a strategic sector, and whether Lithuania will be able to achieve its ambition of a fully functioning biotechnology sectoral system of innovation will be explored. With the Lithuanian government declaring that they will intervene to achieve their innovation goals, this paper argues that sound policy intervention is possible and can be done in a way that avoids the limitations of past systemic approaches. The policy approach presented is based on a modified extended industry life cycle, and the movement of system structures through three phases – background, pre-emergence and emergence – and explains how each phase lays the groundwork for transition to the next phase.  相似文献
