The economics of land fragmentation in the north of Vietnam*

Land fragmentation, where a single farm has a number of parcels of land, is a common feature of agriculture in many countries, especially in developing countries. In Vietnam, land fragmentation is common, especially in the north. For the whole country, there are about 75 million parcels of land, an average of seven to eight plots per farm household. Such fragmentation can be seen to have negative and positive benefits for farm households and the community generally. Comparative statics analysis and analysis of survey data have led to the conclusion that small‐sized farms are likely to be more fragmented, and that fragmentation had a negative impact on crop productivity and increased family labour use and other money expenses. Policies which allow the appropriate opportunity cost of labour to be reflected at the farm level may provide appropriate incentives to trigger farm size change and land consolidation. Policies which tip the benefits in favour of fewer and larger plots, such as strong and effective research and development, an active extension system and strong administrative management, may also lead to land consolidation.     

Trade Verticality and Structural Change in Industries:The Cases of Taiwan and South Korea

This paper documents that a significant portion of trade for Taiwan and Korea follows the trend of world trade in moving toward a pattern of vertical specialization (VS). Noteworthy is the manufacturing sector, whose VS shares of exports has been steadily increasing and has accounted for more than 90% of the total VS shares of manufactured exports. For Taiwan, nearly 57% of the growth in exports is contributed by the growth in VS-based trade; for Korea, it is as high as 64%. In the analysis, we compare VS shares of exports with or without input-output circulation among domestic industries in an open economy. Using Taiwan as a case study, we further discuss the implications of trade liberalization through tariff reductions for trade verticality. JEL Classification Numbers: F1, F14     

Fragmentation of land ownership in Slovakia: Evolution,context, analysis and possible solutions

Land ownership fragmentation is currently a very topical issue in Slovakia. In particular, small farmers complain that even 30 years after the end of the previous (“real socialist”) regime, there has been no significant change in the structure of agricultural land use. The subject of the article is not the land fragmentation in terms of use. In Slovakia, the problem is rather the opposite. This contribution deals with fragmentation of ownership that is mostly invisible in the landscape. Usage still dominates over the ownership and the real landowner cannot get his or her own property in a simple way. The reason for this is huge fragmentation of land ownership, which makes it virtually impossible to actually claim it. Well known solution is the land consolidation that does not advance at a rate that would guarantee the rights (and obligations) of all owners in the foreseeable future in Slovakia. Neglecting the land fragmentation by authorities leads to tense situations between landowners and land tenants and also co-causes a stagnation of rural development and issues with landscape protection. The paper describes the specific state of land ownership in Slovakia and attempts to explain this complicated situation on a sample of 50 historical and modern ownership documents. This contribution has the ambition to specify the largely yet unresolved problems that arise from the current state of massive fragmentation of land ownership. The aim of the paper is also to fill in the information gap on the topic, not only in the national context.     

Liquidity provider incentives in fragmented securities markets

We test theoretical predictions of changes in make/take fees in a setting with isolated make rebates for liquidity providers on a single trading venue (Xetra) by examining the impact on both Xetra and the overall market. The rebates lead to higher quoted depth but do not change bid–ask spreads or trading volume on Xetra. For the overall market, no change in trading volume or liquidity is observable. This shows that market participants redistribute their orders to the venue offering fee rebates rather than providing additional liquidity to the overall market. Consequently, the impact of fee changes depends on the setting.     

Resolving identity ambiguity through transcending fandom

Identity construction involves accumulating cultural, social, and symbolic capital, with initial endowments being accrued through socialization into one’s habitus. This research explores the experiences of individuals that feel a lack of capital, which leads to ambiguity regarding their identities and places in the world. Through in-depth interviews, this interpretive research shows that such individuals may turn to fandom for gaining status and belonging. Fandoms are consumption fields with clear, limited forms of cultural capital. Through serial fandom and engagement with fandom in different ways, individuals were able to learn the skill of identifying and accruing relevant cultural capital. The skill became decontextualized and recontextualized, allowing individuals to transcend fandom and accrue general forms of cultural capital. Learning the skill aids individuals in dealing with the simultaneously debilitating and empowering freedom of contemporary consumer culture. Moreover, gaining cultural capital could be altogether developing into the form of the process we describe.     

A territorial approach to assess the transition to trellis vineyards in special protection areas for steppe birds in Spain

Traditional vineyards in Spain are being upgraded to trellis vineyards. A key question is to what extent the transition to trellis vineyards is compatible with the environmental preservation goals in Special Protection Areas. This paper presents a GIS-based model to assess the suitability of Special Protection Areas for the development of trellis systems. The model was applied in a Special Protection Area for steppe birds in Castilla-La Mancha, Spain, a region with the largest concentration of vineyards in the world. The model includes three components: (1) a vineyard structure analysis, (2) an analysis of habitat fragmentation, and (3) a suitability analysis. The results showed that 50.9% of the study area, including 82.1% of the existing vineyards, was classified as suitable for transition to trellis systems. In the remaining unsuitable areas an increase in trellis systems should be avoided. The model is a stepping stone for improving the sustainable land use development of Mediterranean agricultural landscapes. Further research is needed to include wider socio-economic and environmental consequences of modernizing viticulture practices.     

Economic,social and political fragmentation: Linking knowledge-biased growth,identity, populism and protectionism

This paper examines how economic fragmentation (widening inequality of skills, income and education) gives rise to social fragmentation (via incompatible social identities), generating political fragmentation (via incompatible economic policies). We consider three value-driven identities: individualism, focused on status concerns, communitarianism, focused on social affiliations, and multi-affiliatedness, encompassing both objectives. Under endogenous identity formation high-skill people are drawn to individualism, the lower-skilled to communitarianism, and those of intermediate skill to multi-affiliatedness. Skill- and education-biased growth leads to increasing social polarisation, expanding the individualistic and communitarian groups at the expense of multi-affiliates. This expands the political constituency for closed policies (such as protectionism, immigration controls and nationalism), even when these policies reduce everyone's living standards. Our analysis thereby helps explain the economic and social underpinnings of populism.

Commonality in liquidity and multilateral trading facilities

We use the introduction of two multilateral trading facilities (MTFs) to examine the impact of market fragmentation on commonality in liquidity. We find that the introduction of MTFs following the Markets in Financial Instruments Directive increases the comovement of stocks’ liquidity with MTF liquidity, while the comovement with the home market liquidity generally decreases. We also find that the higher the MTF trading volume or the number of MTFs trading a stock, the stronger the effect. Further, we find that the commonality in liquidity remains unchanged for a matched control sample of stocks that do not trade on MTFs.     

大学科技园发展中的政府“碎片化”治理对策

大学科技园在国家创新型经济社会发展和文化强国过程中起了重要作用。而政府积极为大学科技园发展提供资金支持、政策助推和服务咨询,是实现大学科技园健康发展的有力保障,但其存在的一些"碎片化"管理问题却也成为制约大学科技园发展的硬伤。新形势下,政府要进一步转变职能,克服"碎片化"管理模式,努力创新我国大学科技园的发展策略,为实现大学科技园可持续发展提供机制保障。
