On farmland prices and rents in Japan

Historically, the Japanese farmland market has been strongly regulated, although fundamental changes in policy were introduced in 1967 and 1980. This article examines the relationship between farmland prices and rents in Japan for 1955–2000 using the cointegration procedure of Johansen et al. (2000) , which admits structural breaks. Results show the presence of a cointegrating relationship with a significant break in 1980. There is Granger‐causality from prices to rents, which suggests that rents are determined within an institutional setting according to farmland prices. The rent–price elasticity is unity, which supports the notion of efficiency in the farmland market.     

Prices paid for farmland in Ontario: Does buyer type matter?

In the wake of the substantial increases in farmland values that have occurred in Ontario since 2008, concerns have been expressed regarding the potential influence of nonfarmer buyers, such as investment companies and foreign buyers, on prices paid for farmland. To examine whether these concerns may be warranted, this paper estimates the impact of nonfarmer buyers on sale prices for farmland in Ontario, using a hedonic approach and farmland sales data from 2002 to 2016. Analysis is also conducted to determine whether marginal implicit prices of specific farm attributes differ between farmer buyers and nonfarmer buyers. The results indicate that nonfarmer buyers have paid higher prices for farmland, but only in near‐urban areas. In addition, differences in marginal implicit prices for farmland attributes are found, where farmer buyers value more highly attributes related to the agricultural productivity of the property while nonfarmer buyers value more highly attributes related to nonagricultural use. These results imply that the higher prices paid by nonfarmers may be attributable to the bid‐rent theory, as nonfarmers may be bidding more than farmers for farmland in near‐urban areas due to higher expected returns from future urban use of the land.     

农地经营权流转价格扭曲的政府干预效应 ——基于边际价格理论的实证分析

研究目的：考察政府不同干预行为对农地经营权流转价格扭曲的影响效应,为完善农地生产要素配置及优化农地市场内外环境等提供政策建议。研究方法： Binary Logistic模型。研究结果：（1）当前农地经营权流转价格本应反映承包地利用产生的经济效益,由土地要素投入产出品的边际收益价值所决定;但受市场机制不完善、乡土伦理规范等多重影响,农地实际流转价格与要素价格间产生差异,表现为农地经营权流转价格扭曲。（2）政府不同的干预行为对农地经营权流转价格扭曲产生差异化效应。政府主导流转的直接干预模式会引起流转价格的高价扭曲,而通过构建流转交易平台、提供补贴等政策间接干预会缓解流转价格的低价扭曲。（3）对土地的经济诉求和保障诉求是造成流转价格扭曲的重要原因。研究结论：农地经营权流转价格的形成应交予市场,政府应避免直接干预造成价格的人为扭曲,可通过土地流转中介组织或补贴政策来间接培育优化农地市场交易环境。     

农村土地流转中土地租金差异化动因及影响研究

随着城镇化的发展,大量农民进城务工,农村土地流转是必然趋势。经过调查研究发现,在土地流转中,不同主体对土地租金的期望不同,进城务工农民对土地租金的期望不高,而留守劳动力对土地的租金要求较高,且期望的租金还要包括劳动力机会成本。留守劳动力对土地租金的博弈直接导致了土地规模化经营中土地租金的高涨,使土地规模经营收益出现倒挂,但政府的补贴又维持了这种不健康的租赁关系。农地租金的非理性增长影响了自耕农的壮大和发展,使农地规模化经营偏向公司化,农业公司对利润的博弈导致了套取政策补贴、农地非粮化等问题,土地规模化经营前景堪忧。建议构建进城农民土地退出机制、扶持培养自耕农、建立多种途径的农业经营合作模式、提高农民社保水平等措施,促进农地经营良性发展。     

Derivation of an aggregate supply curve for U.K. beet production

Abstract

This paper examines the relationship between real agricultural land prices and real rents for farmland using annual data. Taking account of inflation as a third variable there is evidence to suggest that rents and land prices are cointegrated; that is, changes in rents are mirrored in the long run by changes in land prices. It is also found that the implied real rate of return in the land market is around 3%.     

Land economic rent computation for urban planning and fiscal purposes

This article proposes an innovative methodology to compute economic rents of land designed to current or potential offices uses. It consists in the establishment of a cause-and-effect relation between offices’ price levels and correspondent levels of land rent, considering the main factors that influence property prices, the ones that guide public and private activities’ location decisions and the inter-dependencies between land and real estate property markets. The rationale subjacent to this research is that land economic rent is determined by the difference between offices market price and a set of costs correspondent to land acquisition, planning and building processes, and a profit margin. An assessment of surplus values is provided in order to compute it as the difference between total land market value (land economic rent plus economic return on land use) and correspondent tributary patrimonial-value according to legal valuation proceedings (settled on property law). In order to reach these goals, variables that exert influence on urban planning and municipal management were identified, an urban management information system was designed and implemented, and an integrated and interactive model to support decisions in urban planning – concerning real estate offices and land prices and characteristics – was developed. These tools were applied as a case study to Oporto city (Portugal). They embody updating functionalities, setting up as an on-going support to policies of municipal land use management (particularly applied to offices uses). A proposal is made to integrate similar models in territorial plans as valuation tools to support better approaches to assess the impact of planning decisions on real estate and land values, thus informing a more equitable, efficient and local-based tax basis. Implications of this analysis for urban planning and fiscal settings are proposed.     

Reconsidering royalty and resource rent taxes for Australian mining

It is argued that a comparative assessment of a royalty and a resource rent tax as a special tax on the Australian mining industry should recognise the following: the importance of quasi‐rents earned on investments which shift out the mining supply curve over time, the dominance of nonresidents as buyers and as shareholders, and available data on relative costs for mines with more and less favourable natural resource endowments. Comparable tax rates for the two special taxes to generate similar government revenue are derived. For approximate revenue neutral taxes, the efficiency and distributional effects of the royalty and resource rent tax options are assessed and compared. In terms of efficiency, the superiority of one over the other is ambiguous because of imperfect knowledge about key parameters. In terms of returns to Australia, and in particular the aggregate of transfers from nonresident shareholders and export buyers, both provide similar outcomes.     

EXPLAINING THE DISTRIBUTION OF QUOTA RENTS FROM US CHEESE IMPORTS

A theoretical model is outlined to illustrate how rents are generated from import quotas. The model is used to estimate rents from US cheese import quotas; rents are substantial. Relative rent capture by importers and exporters is explained by estimating an industrial organisation-type model. Unequal market power is important in explaining the distribution of rents between importers and exporters. Exporters tend to maintain price-cost margins and let importers capture a larger share as rent size increases.     

Distress rentals and the land rental market as a safety net: contract choice evidence from Tigray,Ethiopia

Rural households in the semiarid Northern Ethiopian highlands are net buyers of food. Crop failure due to erratic and unpredictable rainfall occurs frequently and leads to food shortages and income shocks. The renting out of land may be one of the coping responses of households exposed to shocks. We developed a theoretical household model for poor landlord households capturing their contract choice response to downside production shocks. We tested econometrically whether contract choice may depend on poverty, capital constraints, production risk and random shocks. The multinomial logit model estimates show that poor households experiencing random shocks are more likely to choose fixed‐rent contracts as a distress response to shocks, suggesting that fixed‐rent contracts may be used to meet immediate needs, but at the expense of future incomes. We also found that fixed‐rent contracts are preferred when ex ante production risk is low, while sharecropping is more likely where production risk is high. Finally, we found an indication that the choice of a fixed‐rent contract as a coping response to shocks comes as a last resort after all other means of coping are exhausted.     

关系治理还是契约治理：农地流转治理结构的 转型逻辑与区域差异研究

研究目的：为完善农地产权制度和要素市场化配置机制,从制度、经济与文化三个层面分析农地流转治理结构的转型逻辑与区域差异。研究方法：逻辑演绎法,Biprobit模型。研究结果：（1）促进农地流转从关系治理向契约治理转型的核心驱动因素是产权的界定与实施、流转租金的上涨和人情往来的减少。（2）农地流转治理结构及其转型逻辑存在明显的区域异质性。东部和西部地区更偏向契约治理,中部地区更偏向关系治理。在驱动因素上,东部地区较高的流转租金和完善的土地流转服务是主要的转型驱动力,中部地区的人情文化传统较深,阻碍了农地流转的市场化转型,西部地区的土地确权颁证率较高,发挥出了明显的确权效应。研究结论：（1）完善的农地产权制度是农地流转市场的基石,不仅要保障产权明晰,还要构建有效的产权实施机制;（2）经济利益是驱动农地流转市场转型的重要因素,要促进农地价值形成合理的价格参照系;（3）文化观念是农地流转市场转型的重要支撑,要协调好市场观念与文化传统之间的关系;（4）需因地制宜地推进农地流转市场转型。     

中国农户在农地流转市场上能否如愿以偿?——流转市场的交易成本考察

农地流转是实现规模经营的重要途径,尽管中国农地流转市场发展迅速,但农户在流转市场上能否转入自己想要转入数量的土地尚无人关注。本文利用全国6省1200户2000年和2008年追踪调查数据实证分析农户的流转意愿多大程度上可以在流转市场上得以实现,进而考察流转市场交易成本的存在性、对称性和动态性。研究表明,中国农地流转市场存在明显的交易成本,因此流转市场是不完善的。具体结论:第一,流转市场存在明显进入门槛,进入市场后农户也无法实现完全调整,转入户2000年和2008年分别能实现调整意愿的24%和37%,高于转出户的19%和18%;第二,流转市场的交易成本存在非对称性,转入户比转出户面临的交易门槛高,但进入市场后转入户调整意愿实现程度高于转出户;第三,从2000年到2008年,流转市场的交易门槛显著降低了,但进入市场后调整意愿实现程度并没有显著提高;第四,农资设备和劳动力等要素市场的不完善程度更严重,因此农地流转市场发挥了将土地这种"不能移动"的要素移动起来以迎合那些"本该移动"的要素功能,提高了资源配置效率。政府应进一步提高农地产权稳定性,降低流转市场交易成本,加快农业生产社会化服务业发展,完善农村劳动力市场。     

Credit Market Imperfections and the Distribution of Policy Rents

This article shows that credit market imperfections have important implications for the distribution of policy rents. In a model with land as fixed factor and credit market imperfections, when an area payment is given, land rents go up by more than the subsidy. On aggregate farms may lose from the subsidy. The results depend on the extent to which subsidies have direct and indirect effects on the credit constraints, on whether farms rent or own land, and on farm heterogeneity.     

Healthy Competition to Support Healthy Eating? An Investigation of Fruit and Vegetable Pricing in UK Supermarkets

Governments and public health officials are urging the public to eat more fruits and vegetables to contribute to a healthy diet. However, there is concern that a lack of effective competition amongst supermarket retailers has resulted in inflated prices for these products which are deterring consumers from eating more of these healthy foods. We investigate this by examining the nature and extent of price competition for fresh fruits and vegetables amongst UK supermarket retailers, drawing on a panel of weekly retail and corresponding wholesale market prices over a seven‐year period. We find that the extent of supermarket competition varies across the products, being quite intense on some but much weaker on others, where the retailers do not fully respond to each other's prices and where the extent of their competitive interaction varies significantly with each other.     

The political economy of farmland ownership regulations and land prices

One of the most ubiquitous forms of agricultural regulation is a restriction on farmland ownership. One Canadian example of a farmland ownership restriction is The Saskatchewan Farm Security Act (FSA), passed in 1974. The purpose of this article is to explain, using a political economy framework, why the FSA was implemented and to estimate the effect of the FSA on Saskatchewan farmland values. A Present Value (PV) model is used to estimate the relationship between land values, rents, and the regulation. The Hausman endogeneity test reveals that the regulation variable is endogenous with the land price. The sign of the regulation variable is negative, which fits with the theory, i.e., the more stringent the regulation the lower the land value. We estimate that the regulation lowered Saskatchewan farmland prices by an average of 4 to 34 US$/acre, depending on whether ordinary least squares (OLS) or two‐stage least squares (TSLS) is employed in the estimation, over the period of 1974–2001.     

Farmland prices, structural breaks and panel data

Previous time series evidence has indicated that farmland pricesand cash rents are not cointegrated, a finding at odds withthe present value model of farmland prices. We argue that thisfailure to find cointegration may be due to low power of testsand to the presence of structural change representing a shiftingrisk premium on farmland investments. To accommodate this possibility,we use panel unit root and cointegration methods that are morepowerful than conventional time series methods and allow forbreaks in the cointegration relationship. Our results, basedon a large panel covering 31 US states between 1960 and 2000,suggest that the present value model of farmland prices cannotbe rejected.

Price shock transmission: evidence from the wheat‐bread market value chain in Ethiopia

This study assesses the degree of vertical price transmission along the wheat‐bread value chain in Ethiopia. This is pursued by applying a vector error correction model and an impulse response analysis using monthly price data for the period 2000–2015. Our analysis considers transmission of price shocks across different market levels, including from the international and domestic wheat grain markets at the upstream to the domestic wheat bread market at the downstream of the value chain. The empirical findings indicate that significant cointegration exists across prices of the different market stages. There is a transmission from international prices to domestic prices at downstream markets, in particular to flour and bread prices. Prices at upstream markets are largely influenced by the domestic wholesale market. In general, the speed of adjustment is quite slow with a half‐life of about one year for restoring the equilibrium price relationship. As price margins between the different market stages in the value chain have substantially decreased in the last 15 years, higher transmission, and thus exposure to international market shocks, can be expected in the future. The results also show that causal relationships exist between prices at different market stages—with the wholesale market identified as the key market level where prices and price expectations are formed.

The Incidence of EU Per‐Hectare Payments on Farmland Rental Rates: A Spatial Econometric Analysis of German Farm‐Level Data

This article analyses determinants for 2001 farmland rental prices from 3,819 farms in Germany. Based on specification tests we estimate a general spatial model to account for both spatial relationships among rental prices of neighbouring farmers and spatially autocorrelated error terms. A €1 per hectare higher rental price in a farmer’s neighbourhood coincides with a €0.72 higher rental price paid by the farmer. The marginal incidence of EU per‐hectare payments paid for eligible arable crop land on rental rates amounts to €0.38 for each additional €1 of premium payments. Regional livestock density, which is indirectly influenced by different policies, is also a major determinant of rental prices. Results are confirmed by sensitivity analyses. Consequently, German farmland rental rates are heavily influenced by agricultural policy instruments and therefore, these policies exhibit substantial distributional effects.     

Testing vertical price transmission for Vietnam's Robusta coffee

Vietnam has undergone market reforms over the last three decades; and as a consequence, the coffee sector has become increasingly market‐driven. The success of the government's liberalisation policies in terms of market efficiency is investigated by examining the transmission of both positive and negative price changes for Robusta coffee between export and farmgate prices. We used a threshold vector error correction model and high‐frequency daily data. The primary result here is that of a symmetric price transmission between export and farm‐level prices. This result holds when tested with weekly price data, derived from the daily data. Farmgate prices respond faster to decreases than increases in export prices when the long‐run deviation exceeds a certain threshold. These price changes are transmitted within several days. This research also confirms the importance of transaction costs, and other price frictions mostly ignored in prior analyses for coffee.
