关于分配与所有制关系若干问题的思考

共同富裕,消除两极分化是社会主义改革区别于资本主义改革的试金石,也是邓小平的社会主义改革理论中的一个根本问题。正确评估中国贫富差距扩大的形势,促进分配关系的调整和社会公平是经济研究者的职责所在。贫富差距扩大最根本原因在所有制结构的变化,即所有制结构的"公降私升"已经达到影响公有制为主体的临界点,造成这种状况是干扰"公有制经济为主体"的"私有化"倾向。本文认为毫不动摇地发展包括私有经济在内的非公有经济,要以坚持公有制经济为主体、国有经济为主导作为前提,即实行两个毫不动摇,齐头并进,才能保证我国社会主义基本经济制度的巩固发展,永远立于不败之地。     

Diversification and optimal hedges for socially responsible investment in Brazil

This study contributes to the literature on socially responsible investing by examining the diversification potential of commodities, specifically oil, gold and clean energy together with the Brazilian Corporate Sustainability Index (ISE). Multivariate GARCH models are used to model volatility spillovers and conditional correlation in pairs of stocks containing ISE. Specifically, A-BEKK and A-DCC models with spillovers are estimated. The models’ results are used to compute and analyze the optimal weights and hedge ratios for stock portfolio holdings. The greatest benefit from diversification is obtained through the acquisition of gold and then OVX.     

The “New” Kerala Model: Lessons for Sustainable Development

The “Kerala model of development” has won wide international attention for its achievements in regard to social development and, to a certain extent, environmental sustainability. The “old” Kerala model, preoccupied with redistributive policies, failed, however, to induce economic development. As a result, attention is now being given to a “new” Kerala model. The new policy explicitly seeks reconciliation of social, productive and environmental objectives at the local level, and tries to develop synergies between civil society, local governmental bodies and the state government. The new Kerala model thus holds important lessons for participatory, community-based sustainable development in India and elsewhere.     

Does Money Always Make People Happy?

This paper presents an overlapping generations model with private information, in which the use of fiat money and the rampant moral hazard incentives sustain each other. It is shown that there is a monetary equilibrium, despite the fact that the rate of return on the nonmonetary asset is significantly higher than the rate of economic growth in the nonmonetary case; the valuation of money is not necessarily Pareto-improving, but rather can be harmful to almost all generations; an inflationary policy can improve the welfare of all generations except the initial one.

The problem of fair division of surplus development rights in redevelopment of urban areas: Can the Shapley value help?

Many more people are expected to live in urban areas in the coming decades, and much of the physical transformation will take place in the built-up areas of cities. Landownership is a key factor in urban regeneration, and the fair division of benefits is a major obstacle to redeveloping urban land in a cooperative context. This paper aims to show that the Shapley value, a fair division scheme developed within the cooperative game theory framework, can be used to achieve a fair division of the surplus development rights among landowners remolding smaller and irregular parcels into bigger and regular ones, resulting in higher aggregate development rights. The methodology is illustrated by a case study of three parcels selected from the Karabaglar district in Izmir, Turkey, where surplus development rights are available for landowners cooperating for land amalgamation. The findings show that the Shapley values for the landowners satisfy the core conditions of the game and landowners can benefit from the highest possible development rights and share the surplus fairly. However, the current institutional setting has to be restructured to apply such division schemes.     

Learning pathways for energy supply technologies: Bridging between innovation studies and learning rates

Understanding and supporting learning for different emerging low carbon energy supply technology fields is a key issue for policymakers, investors and researchers. A range of contrasting analytical approaches are available: energy system modelling using learning rates provides abstracted, quantitative and output oriented accounts, while innovation studies research offers contextualised, qualitative and process oriented accounts. Drawing on research literature and expert consultation on learning for several different emerging energy supply technologies, this paper introduces a ‘learning pathways’ matrix to help bridge between the rich contextualisation of innovation studies and the systematic comparability of learning rates. The learning pathways matrix characterises technology fields by their relative orientation to radical or incremental innovation, and to concentrated or distributed organisation. A number of archetypal learning pathways are outlined to help learning rates analyses draw on innovation studies research, so as to better acknowledge the different niche origins and learning dynamics of emerging energy supply technologies. Finally, a future research agenda is outlined, based on socio-technical learning scenarios for accelerated energy innovation.     

Network based definition of functional regions: A graph theory approach for spatial distribution of traffic flows

Functional regions are autonomous (internally coherent and externally self-contained) spatial structures based on vector data, so-called spatial interactions. Typically, travel-to-work, travel-to-school flows and migrations are analysed by various methods of functional regional taxonomy in order to define functional regions. There is still another type of statistically recorded vector data which has, up to now, rarely been used for this purpose: traffic flows. However, these data differ distinctly from the above mentioned flows. In this paper we pursue two objectives: (i) to define functional transport regions based on a graph theoretic analysis of individual traffic flows, and (ii) to add knowledge to the issue of the self-containment of functional transport regions. The specific nature of transport data compared to the above-mentioned spatial interactions requires a specific methodological approach, which is presented in the paper. The existing graph theoretic procedures do not seem suitable for the definition of functional transport regions due to data specifics. Therefore our analysis is based on a rough analogy to the minimum cut method – we identify minimum flows in a graph representing a transport network. The territory of the Czech Republic is used as the example. Two regional systems are defined (based on 2000 and 2016 data) and compared in time. The paper achieves two main findings. First, the proposed methodological approach allows us to define autonomous functional transport regions, and the means to calculate their self-containment is discussed. Second, functional transport regions in the Czech Republic show unexpected stability over time compared to functional regions based on such spatial interactions as commuting flows.     

Examining the effect of flow experience on online purchase: A novel approach to the flow theory based on hedonic and utilitarian value

The literature indicate that when flow is approached as unidimensional, its effects on online purchase intention are always positively significant, however the results of the studies where the flow is approached as a multidimensional level, is far from indicating a general tendency. The inconsistent results appeared in the literature are regarded as a result of overlooking both the utilitarian and hedonic significance of research context and the hedonic and utilitarian characteristics of the flow's sub-dimensions. In this direction, the effects of flow on online purchase intention are examined upon consideration of those two factors. Research's data were gathered via e-mail survey from an online shopping website's database. A total of 490 samples obtained in this study were analyzed with structural equation modeling. The results indicates that the flow's most valuable antecedent is feedback in the context of online purchase. The dimensions of “enjoyment”, “perceived control” and “merging of action and awareness” has positive and time distortion has negative significant effects on online purchase intention. However, no significant effects of the concentration and curiosity on online purchase intention were determined.

民间金融与中小微企业共生性研究

民间金融内生于中小微企业的融资需求之中,并形成了互利共生的关系。通过对民间金融规模进行测算,然后建立民间金融和中小微企业的共生模型,测算出2001~2012年我国民间金融和中小微企业之间的共生度和共生系数,结果表明中小微企业对民间金融的影响要小于民间金融对中小微企业的影响。因此,政府应明确民间金融的合法地位,并进行必要的监管和风险防范,努力将民间资金纳入到体制内循环中。
