In many developing and transition economies Mafia-like activities are rampant. Extortion and other forms of predation lower profitability in private businesses and distort investment incentives. Incorporated in a model of industrialization, bimodal club convergence may result. Economies may get stuck in a Predators’ Club characterized by a vicious cycle of poverty and predation. Societies with a low flow of new entrepreneurs are especially vulnerable to predation and never get out of this club. Poor societies with a high flow of new entrepreneurs, however, may grow out of the trap and join the rich Producers’ Club.  相似文献

The aim of this paper is to study wood consumption during the industrial expansion which took place in the western world in the second half of the nineteenth and the first decades of the twentieth century, through the analysis of the case of Spain. For this purpose, we present the series of Spanish wood consumption both as a raw material (WRM) and as firewood (FW) between 1860 and 1935 and we carry out two exercises with these series. The first calculates the intensity of use (IOU), which relates wood consumption in physical terms with the evolution of the GDP. The second, more complex, exercise estimates a standard consumption function that allows us to know the elasticity of WRM with respect to the GDP, the Spanish price of wood and the Spanish price of a substitute material like iron. Based on our results, we discuss the lower dependence of the Spanish industrial economy on wood, the “liberation” of forest areas that may have occurred in Spain as a result of industrialization, and to what extent the trends observed for the Spanish case can be extrapolated internationally. The main conclusion is that industrialization transformed the uses of wood and, though the importance of this resource per unit of GDP decreased, its overall consumption increased, generating greater pressure on forests at an international level.  相似文献

To meet the sustainability challenge private companies must implement corporate strategies and adopt novel technologies. The technical and social embeddedness of industrial production systems, however, complicates these systems' transition towards sustainability. In the paper, mechanisms and conditions are reported for the development and implementation of waste management options in embedded industrial production systems. The focus is on the Dutch zinc production industry, which had to deal with a major waste problem; the generation of jarosite. The industry's options were to increase the jarosite waste storage capacity, to develop a jarosite treatment process or to switch to a zinc-ore of low-iron content whereby no jarosite waste would be generated anymore. Required conditions appeared to be a combination of technological capability and technical embedding and favourable economics. Case study research, however, revealed that adequate stakeholder management is crucial to address social pressure exerted and to obtain external acceptance for any transition strategy. Whilst appropriate, internal technological capabilities are important, effective interactions with and enrolment of various firm-external actors are crucial. In the case of zinc, access to the heterogeneous external actor network was critical for the development of the jarosite treatment solution direction. In conclusion, both the technical, organizational and social embedding of new technologies are crucial for successful implementation.  相似文献

This paper looks at the relations that exist between standardisation and user-side innovation in ICT. Some necessary background information are followed by a discussion of how standards and user-side innovations are shaped. A mutual influence between standardisation and innovation can be identified. To avoid the emergence of standards that are beneficial only for a handful of users a co-ordinated representation of users in standards setting is suggested.  相似文献

The potential duration of benefits is generally viewed as an important determinant of unemployment duration. This paper evaluates a unique policy change that prolonged entitlement to regular unemployment benefits from 30 weeks to a maximum of 209 weeks for elderly individuals in certain regions of Austria. In the evaluation, we explicitly account for the fact that the program was an endogenous policy response to deteriorating labor market conditions for older workers in certain regions and sectors. The main results are: (i) REBP reduced the transition rate to jobs by 17%; (ii) accounting for endogenous policy adoption is important and quantitatively significant.  相似文献

In this paper, we report on an equilibrium with market dominance that exists in a simple two-firm model that features neither entry barriers nor sophisticated punishment strategies. This equilibrium induces an intertemporal market division in which the two firms alternate as monopolists - despite the fact that the model also sustains a Cournot duopoly. Even when initially both firms are active in the market, the alternating monopoly reveals itself rather quickly. Moreover, it Pareto dominates the Cournot equilibrium - as it is close to the cartel outcome. Several examples of what well may be such alternating monopolies are presented.  相似文献

What are the most effective learning strategies for firms given the characteristics of their knowledge environment? This paper addresses this question by documenting the major changes in the knowledge environment of the pharmaceutical industry, with a particular emphasis on the period since the emergence of biotechnology, and discussing the related changes in the learning strategies of established pharmaceutical firms. Both the historical analysis and a review of the empirical research on organizational learning and knowledge transfer reveal a strong emphasis of firms on external learning through interfirm collaborations and sourcing of external knowledge. This learning strategy seems to be driven by the speed, uncertainty, and dispersion of knowledge developments in the industry. Studying the connections between the knowledge environment and the effectiveness of organizational learning processes is important to understand organizational change and adaptation, and is an area of research that deserves further attention.  相似文献

I note an important distinction between the optimal price of environmental quality in a second-best world and the optimal level of environmental quality. Using an analytical general equilibrium model, I show that for reasonable parameter values, an increase in tax distortions (arising from an increase in required tax revenues) leads to a fall in the optimal Pigouvian tax rate even while environmental quality improves. In general, knowledge of the direction of changes in optimal environmental tax rates due to changes in the economy is not sufficient for understanding the impact on environmental quality.  相似文献

Expectations held by different actor groups are of key importance for the shaping of socio-technical transformation processes. Foresight activities may be interpreted as a means to elicit, aggregate, modulate and contextualize expectations held by different actors. The paper proposes a conceptual framework that allows assessing and reflecting expectations in foresight initiatives that focus on sustainable sector transformations. For this purpose it draws on the recent literature on socio-technical system transformations and social expectation dynamics. The application of the framework is illustrated by experiences gained with the Sustainability Foresight method developed for the case of sustainable utility sector futures in Germany. The process was conceived as a series of participative scenario and strategy workshops involving about 120 stakeholders from the provision, use and governance of utility services.  相似文献

In many OECD countries, statutory corporate tax rates are lower than personal income tax rates. This tax rate difference is often particularly large for small firms. The present paper argues that a reduction of the corporate tax rate below the personal tax rate is an optimal tax policy if there are problems of asymmetric information between investors and firms in the capital market. The reduction of the corporate tax rate below the personal tax rate encourages equity financing and thus mitigates the excessive use of debt financing induced by asymmetric information. Our main theoretical result stands in marked contrast to the traditional view of corporate taxation and corporate finance theory, according to which there is a tax disadvantage to equity financing. More recent empirical evidence on this issue, however, is in line with our result.  相似文献

A critical phase of scenario making is the choosing of scenarios. In the worst case, a futures researcher creates scenarios according to his/her subjective views and cannot see the real quality of the study material. Oversimplification is a typical example of this kind of bias. In this study, an attempt towards a more data sensitive method was made using Finnish transport policy as an example. A disaggregative Delphi method as opposed to traditional consensual Delphi was applied. The article summarises eight Delphi pitfalls and gives an example how to avoid them. A two-rounded disaggregative Delphi was conducted, the panelists being representatives of interest groups in the traffic sector. Panelists were shown the past development of three correlating key variables in Finland in 1970-1996: GDP, road traffic volume and the carbon dioxide emissions from road traffic. The panelists were invited to give estimates of their organisation to the probable and the preferable futures of the key variables for 1997-2025. They were also asked to give qualitative and quantitative arguments of why and the policy instruments of how their image of the future would occur. The first round data were collected by a fairly open questionnaire and the second round data by a fairly structured interview. The responses of the quantitative three key variables were grouped in a disaggregative way by cluster analysis. The clusters were complemented with respective qualitative arguments in order to form wider scenarios. This offers a relevance to decision-making not afforded by a nonsystematic approach. Of course, there are some problems of cluster analysis used in this way: The interviews revealed that quantitatively similar future images produced by the panelists occasionally had different kind of qualitative background theory. Also, cluster analysis cannot ultimately decide the number of scenarios, being a choice of the researcher. Cluster analysis makes the choice well argued, however.  相似文献

This study presents a practical case application of socio-technical framework to assess and predict the development of cyber-infrastructure (CI) in Korea. Applying a socio-technical system approach to CI, this paper attempts to gain a clear understanding of how CI will evolve and stabilize in the cyber environment. It investigates the complex interaction between social and technical aspects of CI by highlighting the co-evolving nature, diversity, and interface which constitute the next generation network environment. It describes the challenges in developing, deploying, and maintaining the diverse components of CI and provides a snapshot of Korea's current approach to supporting members in meeting this challenge. The purpose of this study is to provide insight into these challenges and opportunities by offering a socio-technical analysis of CI development involving the social dynamics and organizational, policy, management, and administration decisions inherent in the design and development of CI.  相似文献

Sustainability science poses severe challenges to classical disciplinary science. To bring the perspectives of diverse disciplines together in a meaningful way, we describe a novel methodology for sustainability assessment of a particular social-ecological system, or country. Starting point is that a sustainability assessment should investigate the ability to continue and develop a desirable way of living vis-à-vis later generations and life elsewhere on the planet. Evidently, people hold different values and beliefs about the way societies sustain quality of life for their members. The first step, therefore, is to analyze people's value orientations and the way in which they interpret sustainability problems i.e. their beliefs. The next step is to translate the resulting worldviews into model-based narratives, i.e. scenarios. The qualitative and quantitative outcomes are then investigated in terms of associated risks and opportunities and robustness of policy options.The Netherlands Environmental Assessment Agency (PBL) has followed this methodology, using extensive surveys among the Dutch population. In its First Sustainability Outlook (2004), the resulting archetypical worldviews became the basis for four different scenarios for policy analysis, with emphases on the domains of transport, energy and food. The goal of the agency's Sustainability Outlooks is to show that choices are inevitable in policy making for sustainable development, to indicate which positive and negative impacts one can expect of these choices (trade-offs), and to identify options that may be robust under several worldviews. The conceptualization proposed here is both clear and applicable in practical sustainability assessments for policy making.  相似文献

Current economic instruments aimed at climate change mitigation focus on CO2 emissions only, but the Kyoto Protocol refers to other greenhouse gases (GHG) as well as CO2. These are CH4, N2O, HFCs, PFCs and SF6. Taxation of multiple greenhouse gases improves the cost-effectiveness of climate change mitigation. It is not yet clear, however, what the effect is of multigas taxation on the distribution of the tax burden across income groups. This paper examines and compares distributional effects of a CO2 tax and a comprehensive tax that covers all six GHG of the Kyoto Protocol. The study concentrates on the Netherlands in the year 2000. We established tax rates on the basis of marginal abatement cost curves and the Dutch policy target. The distributional effects have been determined by means of environmentally extended input−output analysis and data on consumer expenditures. Our results show that taxation of multiple GHG improves not only the cost-effectiveness of climate change mitigation, but also distributes the tax burden more equally across income groups as compared to a CO2 tax. These findings are relevant for the debate on the role of non-CO2 GHG in climate change mitigation.  相似文献

Using firm level panel data from 12 developing countries we explore whether financial liberalization improves the efficiency with which investment funds are allocated. A summary index of the efficiency of investment allocation that measures whether investment funds are going to firms with a higher marginal return to capital is developed. We examine the relationship between this and various measures of financial liberalization and find that liberalization increases the efficiency with which investment funds are allocated. This holds after various robustness checks and is consistent with firm level evidence of a stronger association between investment and fundamentals after financial liberalization.  相似文献

Material flow accounting and analysis (MFA) has been established as an influential framework for quantifying the use of natural resources by modern societies. So far, however, no reference data for overall scale and trends of global extraction of natural resources and their distribution between different world regions has been available. This paper presents the first comprehensive quantification of the material basis of the global economy, i.e. used domestic extraction in a time series from 1980 to 2002. We analyse time trends for major material groups (fossil fuels, metals, industrial and construction minerals, and biomass) disaggregated into seven world regions. This allows for (a) an illustration of the global economy's physical growth driven by worldwide processes of economic integration over the past decades, and (b) an indication of the worldwide distribution of environmental pressures associated with material extraction. The results show that annual resource consumption of the world economy increased by about one third between 1980 and 2002. This indicates that scale effects due to economic growth more than compensated for other effects, such as the relative increase of the service sectors' contribution to GDP (structural effect) and the use of new production technologies with higher material and energy efficiency (technology effect). The observed growth of natural resource extraction is unevenly distributed over the main material categories, with metals showing the highest growth rate. The regional analysis shows the increasing importance of Asia and Latin America in global resource extraction. On the global level, material intensity, i.e. resource extraction per unit of GDP, decreased by about 25%, indicating relative decoupling of resource extraction from economic growth. The paper concludes with policy recommendations for a more sustainable use of natural resources.  相似文献
