The Amazon is the largest tropical forest area on Earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large‐scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so‐called “arc of deforestation”. Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and 1ivestock economics.studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications. 相似文献

This paper is focused on the cost of raising capital in Germany. A cross-sectional analysis of flotation cost data for 117 IPOs over the years 1993–1998 is presented. We find average flotation costs to be 7.77 percent of gross proceeds, while underwriting fees average 5.01 percent. Our results extend the literature in two important directions. First, contrary to the conventional economies of scale view we find marginal spreads to be rather constant in gross proceeds and to be higher for more risky and more complex offerings. Fixed costs amount to 5 to 9 percent of underwriting fees. Second, by applying a principal component analysis we find issue size, an issuer risk factor, and an offering method complexity factor to have an economicaly meaningful impact on underwriting fees. 相似文献

一个培育我国外贸新增长点的设想--发展环渤海区域外贸城市群 总被引:3,自引:0,他引:3
对外贸易的拉动作用是实现我国十六大经济增长目标的重要保证。但是,反观当前的国内外环境,我国进出口贸易的发展遇到了诸多困难。欲解决这些问题,必须进行制度创新,其中培育城市群是一种可行的办法。而环渤海区域以其特有优势,成为培育对外贸易城市群的首选。为此,我国需要在环渤海区域大力发展高新技术产业,培育产业集群,引导民营企业发展,以及发挥政府的政策作用。 相似文献

生态环境的恶化与乡村社会控制--以清代徽州的棚民活动为中心 总被引:4,自引:1,他引:3
从明后期开始进入徽州地区的外地棚民,利用当地丰富的自然资源,进行各种经济活动。在当时的社会条件制约下,此类经济活动耗费了大量的资源,破坏了徽州农村的生态环境,损害了地方和国家的利益。针对这一问题,清代徽州乡村社会各种民间力量和官方联合展开了一场声势浩大的驱禁棚民运动,取得了预期效果。 相似文献

This paper investigates the existence of a correction mechanism for mis-pricing between Japanese stock and bond. By this correction mechanism we mean that when deviations occur from the equilibrium levels of the expected return differentials between stock and bond — the risk premium differentials, the market will tend to correct the mis-pricing and bring the expected return differentials back to the equilibrium levels. We assume that the yield spread between the predicted earnings price ratio of stock and the yield to maturity of bond reflects the risk premium between stock and bond, and estimate the equilibrium risk premium differentials and mis-prices between stock and bond by modelling their behaviors with a statistical yield spread model (SYS). Empirical results strongly indicate the existence of the mis-pricing correction mechanism, suggesting the inefficiency of securities markets. 相似文献

Among the economies with a Currency Board System (CBS), Hong Kong (HK) is probably the one with the largest and most developed financial sector, as well as the highest capital mobility. Hence, studying HK’s CBS is not only crucial to HK, but also important for the understanding of the modern CBS. This paper outlines the major monetary reforms in HK since the late 1980s. The impacts of these reforms and the 1997–1998 Asian Financial Crisis are then examined empirically. We focus on the differentials between the US and HK interbank interest rates. We assume the conditional-mean equation follows an autoregressive process and the conditional-variance equation follows a generalized autoregressive conditional heteroscedasticity process. This model captures the time-varying level and volatility of the differential. In light of the empirical results we provide an assessment of the reforms in HK. 相似文献

转移价格是指跨国关联企业之间进行交易时使用的价格。70年代以后,随着日本经济实力的增强,日本企业经营国际化迅猛发展,出现了许多利用国际关联企业转移所得而避税的情况,而日本有关跨国公司转移定价的税制的实施,使这一避税现象得到了了的避免。随着我国加入WTO后外资的更多进入,加强转移定价的管理势在民行,学习发达国家的先进做法,将有助于我们在这方面少走弯路。 相似文献
