Because of the share dynarnicity being adopted which shows the flexible strong points, the shares of ownership and contracting power avoid many unnecessary otiose disputes on income of glebe deal, adding the stability to the glebe usufruct deal.

The paper proposes a broad argument that the end of state–led development from the 1970s coincided with (i) the final wave of major redistributive land reform, and its place within transitions to capitalism, that lasted from about 1910 to the 1970s, and (ii) the beginnings of contemporary 'globalization'. Self–styled 'new wave' agrarian reform in the age of neo–liberalism, centred on property rights, is unlikely to deliver much on its claims to both stimulate agricultural productivity and reduce rural poverty. The reasons are grounded in the basic relations and dynamics of capitalism, and how these are intensified and reshaped by and through globalization. Understanding these processes, with all their inevitable unevenness, requires (i) recognizing that the historical conditions of the 'classic' agrarian question no longer apply, and (ii) developing the means to investigate and understand better the changing realities facing different agrarian classes within a general tendency to the concentration of capital and fragmentation of labour, including how the latter may generate new agrarian questions of labour.  相似文献

This paper analyzes the dynamic relationship between primary and secondary mortgage markets and the short-term and long-term market interest rates. Using a series of monthly data on fixed rate mortgage rates and GNMA rates, we explore the dependence and speed of adjustment in these primary and secondary mortgage rates to each other as well as to the long and short-term government rates. The results indicate that residential mortgage rates in general, appear to follow the long-term rate and are not very sensitive to movements in the short-term interest rate.  相似文献

This paper contributes to the debate over land tenure in rural China by extending its spatial coverage to the country’s extensive rangeland regions. Key characteristics of pastoral tenure, identified from field appraisals in western China, include group tenure and fuzzy boundaries. Although these characteristics give rise to efficiency concerns, from a new institutional economics perspective they also facilitate the realization of certain benefits, benefits that could represent opportunity costs of further exclusiveness. The strengthening of rangeland co-management may constitute a more appropriate path to institutional improvement than the establishment of the household ranch, the current goal of national rangeland policy.  相似文献

强化处置闲置地   总被引:1,自引:0,他引:1  
闲置地是当前土地资源利用和管理中值得关注的重要问题。闲置地弊端甚多,严重地威胁了子孙后代的生存和社会经济的可持续发展。闲置地本质上是二元土地制度的产物,也是投机因素作祟的结果。强化闲置地的处置须从改革土地制度、规范地方政府行为、无偿收回闲置地、健全政策法规等多方面努力。  相似文献

In this research we use a continuous payment formula for duration to examine the price behavior of a fixed-rate level payment mortgage. In the case where the mortgage is held to maturity, duration increases monotonically as term-to-maturity increases, regardless of changes in the market rate of interest. In the case where the mortgage is prepaid prior to maturity, there exists a unique market interest rate below which duration is a monotonically increasing function of time of prepayment, but above which duration has a global maximum at some time of prepayment prior to the term-to-maturity.  相似文献
