The last generalists

Abstract

The general trend of research specialisation in economics has contributed to the marginalisation of the history of economic thought. However, it has also led to a state of fragmentation in the profession and thereby increased the costs of neglecting the history of economic thought. This paper argues that historians of thought can help to counteract fragmentation because they are special generalists that fulfil multiple functions, for example, in the education of economists, the detection of blind spots in modern theories and the identification of routes for innovation by backtracking.

Land consolidation – A great need to improve effectiveness. A case study from Poland

Among the different factors which have an influence on the profitability of small and medium-size farms, a very significant and sometimes even crucial role is played by the unfavourable parameters of land fragmentation (LF). However, this adverse limiting factor can be improved in a relatively short time through land consolidation (LC) treatment. The financial support of these kinds of activities is one of the main aspects of the Common Agricultural Policy (CAP), which aims to equalise the conditions for farming production. Since accession to the EU in 2004, Poland is one of the biggest beneficiaries of various financially-supported projects oriented to the development of rural area, where LC work takes a special position.This paper sums up the outcomes of the LC work that was undertaken in Poland over the period 2007–2013. The results of the investigation delivered the information about the effectiveness of LC work at the farm level. Also, the efficiency of the existing funding strategy of LC work was evaluated. Additionally, the findings revealed poor effects of land swapping and re-parcelling activities, which is disturbing bearing in mind the financial scale and the amount of time spent conducting these actions. As a remedy, several solutions for improvement of the inefficient LC proceedings were proposed.     

Whereto land fragmentation–land grabbing in Romania? The place of negotiation in reaching win–win community-based solutions

The present study seeks to discuss and advance the understanding of land fragmentation and land grabbing within Romania's economic historiography landmarks, depicting how the origins of the land property issues are deeply embedded politically, socially, and culturally in history and still strongly exist in today's collective mind. Scientific evidence on the perceptions and behaviors of land owners regarding land grabbing was obtained through a non-probabilistic survey. The data collection instrument was a structured questionnaire, which was applied through face-to-face interviews to a sample of 52 Romanian land owners from various regions of the country. The results show that in the land owners’ perception, if land is sold to foreigners, national security is the most vulnerable aspect. Regarding the preference for the nationality of the land buyer, the majority of the people investigated prefer to sell to a Romanian buyer, thus making a clear statement in favor of the Romanian ownership of the land. The empirical results are placed in the context of a bottom-up approach—negotiation, with a high potential, unexplored in Romania, for implementing win–win agricultural solutions. Negotiation is valued as part of the answer to land fragmentation–land grabbing, a “back and forth” matter. The study recommends several measures for land use policy, tailored according to specific Romanian conditions, such as using an open access electronic registry of foreign land acquisitions, establishing a threshold for these acquisitions, and securing the preservation of the agricultural destination of land. In a political and economic context where land fragmentation and grabbing are two realities that are hard to deny and separate, a significant implication of the research is the enrichment of knowledge related to the sources of the “chronical” nature of fragmentation and to land owners’ attitude toward land grabbing, thus contributing to the design and implementation of future integrative land use solutions.     

The Farmland Rental Paradox: Extreme land ownership fragmentation as a new form of land degradation

Extreme farmland ownership fragmentation is becoming a limiting factor for sustainable land management in some countries. Scattered, excessively small parcels cease to be viable for individual farming, and owners feel forced to rent these parcels to larger enterprises farming on adjacent land. Our study demonstrates a phenomenon that we call the Farmland Rental Paradox, where very small parcels tend to create large production blocks by being rented to larger farmers, and therefore to significantly homogenize the land-use pattern. The parcel size established as the threshold for this phenomenon is 1.07 ha. Below this threshold, the smaller the parcels were, the larger the blocks that they tended to create.Using the example of the Czech Republic, a state with extremely high farmland ownership fragmentation, it is demonstrated that this phenomenon can currently determine the land use of up to 40% of the country's farmland. Our study also points to other countries where this phenomenon may apply, especially the transitional countries of Central and Eastern Europe.The study discusses the tempo of the fragmentation process, which accelerates exponentially in countries with the equal inheritance system. It goes on to discuss defragmentation, social impacts of the dominance of the land rental market, and environmental impacts of significant homogenization of the land-use pattern. The serious negative impacts of extreme land-ownership fragmentation show that this phenomenon can be considered as a significant form of land degradation.     

Socioeconomic drivers of forest loss and fragmentation: A comparison between different land use planning schemes and policy implications

Forest loss and fragmentation, which generate various negative environmental and ecological consequences, have become widespread phenomena across the globe. Motivation to investigate the underlying drivers is essential for land use planning and policy decision making. This paper characterizes forest loss and fragmentation from 1979 to 2014 in the Ningbo region (China) using multitemporal satellite imageries and a set of landscape metrics (area-weighted mean patch area, edge density, area-weighted shape index, Euclidean nearest neighbor distance, effective mesh size and total area); and then quantifies the responsible socioeconomic drivers (economy, social activities, science and technology, culture and policy, demography) under different land use planning schemes (urban and non-urban) using multivariate linear regression. Results show that the two zones present identical trend of intensifying forest loss and fragmentation but differ in changing magnitude and speed. More specifically, forest loss and fragmentation in the non-urban planning zone occurs at a significantly higher pace and magnitude. For the urban planning zone, population pressure, economic growth and fruit consumption are the primary drivers of forest loss, while forest fragmentation is mainly driven by economic openness, cash crop consumption and environmental protection consciousness. For the non-urban planning zone, income increases, fruit consumption and infrastructure development are the primary drivers of forest loss, while infrastructure and tourism development are the major drivers of forest fragmentation. Besides, forest loss and fragmentation in the two zones are both heavily subjected to land use policy. The variance partitioning analysis highlights that the policy driver is the most influential one and economic driver also has strong effect on forest loss and fragmentation in the urban planning zone. For the non-urban planning zone, the influence of policy driver is the strongest and social activity is also very powerful. These results provide compelling evidence that land use planning fails to play an efficient role in protecting forest resources in the Ningbo region. The failure should be attributed to several issues associated with land use planning and forestry governance that widely exist in China. We finally propose some pertinent implications and suggestions for China’s land use planning and forest policy. This study is believed to advance the understanding of the socioeconomic drivers of forest loss and fragmentation. It therefore provides some new insights in land use policy.     

农地细碎化对农户农地流转决策的影响研究

研究目的:分析农地细碎化对农户农地流转决策的影响。研究方法:成本—收益理论,排序概率选择模型。研究结果:(1)农地细碎化增加了农业生产成本,降低单位面积农业生产收益,对农户农地最优经营规模产生负向影响;(2)农地细碎化对农户转入意愿产生负向影响,使农地流转市场的需求量减少;(3)农地细碎化对农户转出意愿虽有一定的正向影响,在一定程度上使农地流转市场的供给量增加,但农户转出意愿主要受非农就业影响。研究结论:为活跃农地流转市场,应采取农地整治等措施降低细碎化程度,鼓励新型农业经营组织转入农地,形成适度规模经营的农业生产格局,增加农地流转市场的需求量;此外,应深化城市经济社会体制改革,提供更多更好的非农就业岗位,以吸引农民市民化,使更多的农民愿意转出农地,增加农地流转市场的供给量。     

How Did Finance Capital Infiltrate the World of the Urban Poor? Homeownership and Social Fragmentation in a Spanish Neighborhood

When working‐class localities in developed countries are in question, social fragmentation is often analyzed along ethnic lines. Instead, this article claims that it is more critically fruitful to explore fragmentation in terms of people's relations with the state and different forms of capital. It does this by considering housing in Spain as a key resource that connects state policies both with the forms of reproduction and (dis)organization of the disadvantaged, and with the development of real estate and finance capital. First, it unfolds the historical formation of the Spanish ‘homeownership culture’ and the construction–finance complex. Second, starting from an in‐depth ethnography of a peripheral neighborhood in Barcelona, it emphasizes the embeddedness of recent financialization in the livelihood strategies of poor households. Finally, it shows how the process led to a commodification and erosion of those social relations on which it partially depended, thereby exposing problems for class reproduction and fracture lines among the urban poor.     

The communal roots of entrepreneurial–technological growth – social fragmentation and stagnation: reflection on Atlanta's technology cluster

Why do some entrepreneurial high-technology industrial clusters grow and prosper, while others stagnate? Even after several decades of research, we have yet to find a definitive answer. One of the main debates in the literature revolves around the importance of societal variables, such as the growth of a cohesive community, versus the importance of factor availability, such as the supply of highly educated labour. Employing a critical case study design to analyse the technology industry in metropolitan Atlanta, this article shows that although the availability of certain factors might be necessary, it is not sufficient without the crystallization of a cohesive social structure. More specifically, we argue that unless a local high-technology industry develops rich multiple, locally centred social networks, which embed companies in the region, cluster development will stagnate. This is true even if the region is extremely rich in all the factors identified as growth-inducing in the literature.
