The literature on the rural credit market in India (and elsewhere) has generally assumed that peasant farm households are rationed in their access to subsidized formal credit. Because of a lack of infrastructure and poor access to institutional credit, such farmers are exploited by means of an interlocked market connecting informal credit to the sale of paddy. The resulting gap, between the sale by a borrower of paddy at a predetermined low price, and the price of this commodity on the open market, constitutes the amount of what is termed a distress sale. The latter is itself influenced by the bargaining capacity (or lack thereof) of the peasant farmer who borrows on the informal market. Also of importance in determining whether or not a cultivator is compelled to resort to the informal credit market – and thus into an interlocked arrangement – is the need for additional liquidity to meet production costs and/or household consumption, as well as the monopsony nature of the paddy market. Data from Kalahandi district in Orissa suggest that access to formal credit is limited in rural areas although there exists a high demand for it, that a high degree of credit rationing by the formal lender occurs, and that poor implementation by the state of minimum support price policy all contribute to the need for informal loans and its attendant interlinkage.  相似文献

Zusammenfassung Nach einer Entscheidung des Bayerischen Verfassungsgerichtshofs kann ein Bauleitplan wegen Versto? gegen das Willkürverbot aus Gründen des Umweltschutzes nichtig sein. Diese auf eine Popularklage ergangene Entscheidung er?ffnet die Frage, ob der Verfassungsgrundsatz des Willkürverbots auch im Rahmen von Verwaltungsakten herangezogen werden kann. Der Beitrag bejaht diese M?glichkeit.  相似文献

The legislative process in the tax field and the administrative process for the issuance of regulatory and interpretative material by the Treasury Department are closely coordinated. The same persons and interests both inside and outside of Government are involved in both processes. There is thus continuity of expertise, understanding of what is at stake, adversary viewpoints, and Washington knowhow. The preparation of administrative material within the Treasury is a task for those technical personnel and policy officials who in varying degrees also have a voice in the preparation of the Treasury's legislative position and the legislative development of statutory language. The outside forces who watch legislative activity also closely watch administrative activity and seek to shape the latter just so they do the former. The response of the Treasury is much the same in both situations, and governed by the policies, attitudes and predilections of tax policy officials and career personnel.  相似文献

A longitudinal study of 25 families, with children aged 14 months—5 years, in joint custody, is reported. Varying motivations that lead divorcing parents to undertake and sustain joint custody are discussed, together with the stresses and gratifications of these arrangements for the parents and children. Findings are that where both parents are motivated primarily by interest in the child, where the parenting is sensitive and where the child is shielded from interparental conflict, young children do well. Such families were not the majority in this study. Significant differences emerged in the adjustment of the 1–3 age group as compared with the 3–5 age group which point to greater difficulties for the 3–5 year-olds.  相似文献

DNA profiling evidence presented in court should be accompanied by a reliable estimate of its evidential weight. In calculating such statistics, allele frequencies from commonly employed autosomal microsatellite loci are required. These allele frequencies should be collected at a level that appropriately represents the genetic diversity that exists in the population. Typically this occurs at broadly defined bio-geographic categories, such as Caucasian or Asian. Datasets are commonly administered at the jurisdictional level. This paper focuses on Australian jurisdictions and assesses whether this current practice is appropriate for Aboriginal Australian and Caucasian populations alike. In keeping with other studies we observe negligible differences between Caucasian populations within Australia when segregated geographically. However segregation of Aboriginal Australian population data along contemporary State and Territory lines appears to mask the diversity that exists within this subpopulation. For this reason datasets collated along more traditional lines may be more appropriate, particularly to distinguish the most genetically differentiated populations residing in the north of the continent.  相似文献
