也论废除农业税制 --兼与财政部财政科学研究所孙东升商榷

近几年来 ,我国经济理论界和实际工作者已开始大声呼吁取消农业税和废除农业税制的问题。《农业经济问题》2 0 0 3年第 3期发表了财政部财政研究所孙东升的文章《论农业税的取消》。孙东升的观点与中央财经领导小组的唐仁健的观点是一致的 ,认为农业税应该取消 ,只是现在还不行 ,“还需要一个较长的时期过程” ,要形成“取消农业税的几个必要条件”。为了向决策者提供一个真实的情况 ,笔者以一个基层实践者的身份 ,也谈谈尽快废除农业税制的问题 ,并与孙东升商榷。一、税费剖析　　所谓现行农业税体制 ,我把它作了一个概括 :在农村依据耕地…     

Patterns in Technical Efficiency and Technical Change at the Farm‐level in England and Wales, 1982–2002

English and Welsh farm‐level survey data are employed to estimate stochastic frontier production functions for eight different farm types (cereal, dairy, sheep, beef, poultry, pigs, general cropping and mixed) for the period 1982 to 2002. Differences in the relative efficiency of farms are explored by the simultaneous estimation of a model of technical inefficiency effects. The analysis shows that, generally, farms of all types are relatively efficient with a large proportion of farms operating close to the production frontier. However, whilst the frontier farms of all types are becoming more efficient through time because of technical change, it is also the case that the efficiency of the average farm for most farm types is increasing at a slower rate. In addition, annual mean levels of efficiency for most farm types have declined between 1982 and 2002. The factors that consistently appear to have a statistically significant effect on differences in efficiency between farms are: farm or herd size, farm debt ratios, farmer age, levels of specialisation and ownership status.     

Re‐evaluating the Harbinson Proposal – Prospects for the EU25: A Note

In this study, we use the Harbinson Proposal and July Framework to compare a ‘likely’ Doha scenario with a realistic baseline. The novelty of this study is that we focus exclusively on the trade‐led welfare impacts in selected EU member states. The important features of this note are the: (i) usage of the latest Global Trade Analysis Project (version 6) data; (ii) focus on EU25 regions incorporating all major Common Agricultural Policy instruments and reforms; and (iii) inclusion of binding tariff overhangs into the Harbinson tariff reductions. Results show the damping effects of tariff‐binding overhangs on welfare outcomes. This and other factors which limit the gains to liberalisation mean that the EU25 only realises 10% of its long‐run welfare gain potential, as defined by complete liberalisation.     

A Statistical Analysis of Wheat Price Fluctuations in England: 1685–1850

For some commodities and time periods, the analysis of price fluctuations must necessarily rely on the existence of price data alone. A theory applicable in such circumstances is outlined for commodities that are storable, traded in open markets and subject to net supply shocks which are heterogeneously distributed across the months of the year. Market prices are predicted to vary autoregressively except at times when wheat stocks become negligible and observed market prices exceed threshold prices (which may themselves differ across months). The model is applied to a monthly time series of wheat prices for southern England from 1685 to 1850. The autoregressive parameter and the threshold prices are estimated, substantial empirical support being found for the models tested. Historical events from the late seventeenth century through to the continental wars in the late eighteenth and early nineteenth centuries are used to illustrate the mechanisms underlying the theory.

A cost-benefit analysis of a public labelling scheme of fish quality

The purpose of this paper is to introduce a new method capable of evaluating the economic welfare for quality graded fish products using the hedonic price method for plaice in Denmark. Today, no labelling scheme exists for the final consumers of different qualities of fish. A scheme only exists at the first hand market. On this basis, a general applicable, theoretical and empirical method is developed to compare the costs and benefits of the hypothetical choice between the total absence of labelling and the presence of a public labelling scheme, which fully informs consumers on the quality and simultaneously allows the producers to differentiate prices between quality grades. It is shown that the economic welfare associated with a public labelling scheme is at minimum €263,000. Sensitivity analysis shows that this result is robust. The policy implication is that a public labelling scheme should not be implemented as the demand and cost functions have low elasticities, implying that the welfare gain is low.     

中国与东盟国家土地税费政策比较与借鉴

为帮助我国企业熟悉东盟市场环境,借鉴完善我国土地财税体制,对东盟与我国的土地税费政策进行了比较研究。与东盟国家相比,我国土地税费政策主要存在地方性土地收费项目繁多、土地税费收益用于民生开支不足、土地税费政策调控房地产市场的作用还没有得到充分体现等缺陷。因此,可以借鉴东盟国家土地税费征收经验,通过正税清费,提高土地税费的市场调控能力,改革财税体制,完善土地收益分配关系,以及加强土地收益使用监管等措施进一步完善我国土地税费政策。     

Land change in the Brazilian Savanna (Cerrado), 1986–2002: Comparative analysis and implications for land-use policy

The Brazilian Cerrado, a biodiverse savanna ecoregion covering 1.8 million km² south and east of the Amazon rainforest, is in rapid decline because of the expansion of modern agriculture. Previous studies of Cerrado land-use and land-cover (LULC) change imply spatial homogeneity, report widely varying rates of land conversion, use ambiguous LULC categories, and generally do not attempt to validate results. This study addresses this gap in the literature by analyzing moderate-resolution, multi-spectral satellite remote sensing data from 1986 to 2002 in two regions with identical underlying drivers. Unsupervised classification by the ISODATA algorithm indicates that Cerrado was converted to agro-pastoral land covers in 31% (3646 km²) of the study region in western Bahia and 24% (3011 km²) of the eastern Mato Grosso study region, while nearly 40% (4688 km² and 5217 km², respectively) of each study region remained unchanged. Although aggregate land change is similar, large and contiguous fragments persist in western Bahia, while smaller fragments remain in eastern Mato Grosso. These findings are considered in the current context of Cerrado land-use policy, which is dominated by the conservation set-aside and command-control policy models. The spatial characteristics of Cerrado remnants create considerable obstacles to implement the models; an alternative approach, informed by countryside biogeography, may encourage collaboration between state officials and farmer-landowners toward conservation land-use policies.     

Exploring agricultural advice networks,beneficial management practices and water quality on the landscape: A geospatial social-ecological systems analysis

Agricultural practices have been linked to detrimental effects on ecosystems, with water quality of particular concern. Research has been devoted to understanding uptake of beneficial, or best, management practices (BMPs) in agriculture; however, sources of advice and subsequent effects on the landscape have not been elucidated. This study set out to understand (1) what sources of information agricultural producers rely on when making land-management decisions; (2) the characteristics of their advice networks; and (3) how the advice network linked spatially to water quality on the landscape. A watershed in Alberta was used as a case study and respondents identified that regional advisors were relied upon most often for advice and these advisors had the most influence on the adoption of BMPs. Results indicate that respondents with connections to regional actors implemented more BMPs that those without. Regional government actors had a greater effect than regional non-governmental actors. Local actors played a lesser role in advice networks related to BMP adoption. A 3D geovisualization was used to explore linkages among advisors, BMPs, and water quality. This technique may be useful for other scenarios and can contribute to policy development and enhanced practices.     

PROBLEMS OF AGRICULTURAL POLICY IN EUROPE–A DANISH POINT OF VIEW

Recent developments in the agricultural situation of Western Europe has led to inceased self-sufficiency in importing countries and stagnation in the world trade of agricultural products. An examination is made of the effects of these developments on Danish agriculture and the Danish economy, which has been subject to a very rapid change of structure. Characteristics of the Danish agricultural support policy are commented upon as well as the issue of price support versus income support in relation to the objectives of greater efficiency and improved farm structure. The importance of other measures is emphasised, including action to impove the mobility of agricultural manpower. On the basis of past experience some comments are finally made about the enlargement of E.E.C. and its possible effects on the world trade, on the situation of overseas producers, including the developing countries, and possible ways of reducing the difficulties.

PRICE-QUALITY RELATIONSHIPS IN A DURABLE ASSET: ESTIMATION OF A CONSTANT QUALITY PRICE INDEX FOR NEW FARM TRACTORS, 1948–1965*, †

Because of the many uses of price indices it is important that they be corrected for quality change. This paper presents a regression approach to the problem of extracting the influences of quality change on price and a price index for new farm tractors is calculated which allows for the considerable, post-war, quality improvements in the input. The results indicate that whilst the average price of tractors has risen rapidly over the post-war period, the true (constant quality) price has shown only a small increase. Some implications of these results are put forward—particularly with regard to the measurement of gross investment and capital stock, and to the importance of input quality change in explaining increasing agricultural productivity over time. Finally, firm level decision making leads to the observed changes over time in the quality demanded of an input: some consideration is given to the place of factor quality selection in firm theory.     

Seasonal variability,land values and willingness–to–pay for a forward wheat contract with protein premiums and discounts

This article investigates the impact of a protein premiums and discounts system on the income stream from growing wheat. Based on a biological relationship between protein and yield in uncertain seasonal conditions, it shows that such a system reduces the expected level and variability of wheat income. It is subsequently argued, using a numerical analysis, that protein payments affect both the attraction to wheat growers of forward contracts and the value of land used for wheat. The nature of both of these impacts is related to the level of seasonal variability affecting the land. Consequently, wheat growers in the more unreliable regions of the wheatbelt may have been particularly disadvantaged by the system.     

Sweetness and Power – Public Policies and the ‘Biofuels Frenzy’

Sweetness and Power – Public Policies and the ‘Biofuels Frenzy’ In the last decade, there has been a huge policy‐led expansion in biofuels production and consumption. This paper presents some of the findings of a funded research project which has sought to identify the drivers of biofuels policies over this period. It focuses on the EU, US and Brazil which, together, represent about 90 per cent of global biofuels markets. Biofuels policies have three key drivers: as a partial substitute for fossil fuels, to lower greenhouse gas emissions; as a way of improving energy security, by diversifying away from fossil fuels and from the limited number of countries with fossil‐fuel reserves; and as a means of promoting rural development, given the opportunities offered by the production of biofuel feedstocks and their processing into biofuels. One particular challenge for both the EU and US has been to create and sustain a broad coalition of stakeholder interests in support of biofuels and biofuel policies. Both have sought to promote ‘conventional’ biofuels now, whilst trying to aid the development of ‘advanced’ biofuels industries that will address problems with existing technologies. The continued failure to deliver significant quantities of advanced biofuels raises questions for biofuels policymakers going forward, not least dealing with the downsides of conventional biofuels that, so far, have not been mitigated by a successful transition to advanced biofuels.
