Farmland prices have risen dramatically in recent years, which has attracted interest from the broader investment community. At the same time, concern is being expressed regarding another bubble in farmland prices. This paper studies and compares the farmland price to cash rent ratio (P/rent) with the price to earnings (P/E) ratio of stocks. We find that the farmland P/rent ratio has reached historical highs and is currently at the level of the P/E ratio of the S&P 500 during the tech bubble. Data from 1911 to 2012 are used to estimate the beta of farmland, a measure of the risk that farmland adds to a diversified portfolio. The beta is found to be very low over this period. Farmland returns are also regressed against expected and unexpected inflation, and we find that farmland moves relatively close to one-to-one with inflation. We also report 10- and 20-year holding period returns for farmland and find that the relationship between return and the cyclically adjusted P/rent ratio is strongly negative. Moreover, the current cyclically adjusted P/rent ratio is extremely high, indicating a reason for caution when investors are considering farmland purchases.
近年来,农田价格大幅上涨,吸引了更广泛投资界的兴趣。与此同时,也有人担心农地价格会再次出现泡沫。本文研究并比较了农地价格与现金租金比率(P/rent)与股票的市盈率(P/E)。我们发现,农田的P/rent比率已经达到历史高点,目前处于标准普尔500指数在科技泡沫时期的P/E水平。1911年至2012年的数据被用来估计农田的贝塔系数,这是衡量农田给多元化投资组合增加的风险的指标。在这段时间内,贝塔系数非常低。农田收益也对预期通货膨胀和非预期通货膨胀进行了回归,我们发现农田与通货膨胀的变动相对接近于一对一。我们还报告了农田10年和20年的持有期回报,并发现回报与周期性调整的P/rent比率之间的关系是强烈的负相关。此外,目前经周期调整的P/rent比率非常高,这表明投资者在考虑购买农田时有理由保持谨慎。

Linking the Price of Agricultural Land to Use Values and Amenities 农业用地价格与使用价值和便利度挂钩
Pub Date : 2014-10-01 DOI: 10.1093/ajae/aau041

In many areas throughout the United States, the market value of agricultural land exceeds its use value in agricultural production. This deviation is the result of many factors, including urban influence, recreation, mineral extraction, and other natural amenities. This study examines the drivers of the nonagricultural portion of cropland and pastureland values across the United States using a rich geospatial data framework linked to the USDA’s June Area Survey. The analysis suggests that many natural amenities and urban pressures shape the value of US cropland and pastureland, and that development potential is the largest driver of the nonagricultural component of farmland values.
在美国许多地区,农业用地的市场价值超过了其在农业生产中的使用价值。这种偏差是许多因素的结果,包括城市影响、娱乐、矿物开采和其他自然设施。本研究使用与美国农业部6月区域调查相关的丰富地理空间数据框架,考察了美国农田和牧场非农业部分价值的驱动因素。分析表明,许多自然设施和城市压力塑造了美国农田和牧场的价值,而发展潜力是农田价值中非农业成分的最大驱动力。

Are Women Better Bankers to the Poor? Evidence from Rural Microfinance Institutions 女性对穷人来说是更好的银行家吗?来自农村小额信贷机构的证据

Microfinance Institutions (MFIs) provide financial services to the poor and in many ways resemble both banks and non-profit organizations. Many MFIs target women because more women than men are poor, especially in rural areas. Studies show that women manage money differently from men and have different leadership styles. Thus, in credit unions and financial firms, female and male managers achieve different results. In microfinance, gender diversity on the board of MFIs is beneficial, and loans authorized by female loan officers have lower default rates. Motivated by these findings, we ask whether MFIs with a female Chief Executive Officer (CEO) are more efficient at serving the poor without jeopardizing financial sustainability. We adapt the banking approach to managerial (in)efficiency to account for the outreach and sustainability goals of the MFIs, and evaluate whether MFIs' outreach efficiency differs by the gender of their respective CEOs. We estimate a stochastic frontier cost function using the Battese-Coelli (1995) model and the "true" random effects estimators using panel data from over 250 MFIs. We find that MFIs with female CEOs have significantly higher outreach efficiency than MFIs with male CEOs. Similar results are found with a two-step stochastic frontier approach. Overall, the results suggest that promoting gender diversity at the top levels of MFI management is likely to have both social and financial benefits.
小额信贷机构(MFIs)向穷人提供金融服务,在许多方面类似于银行和非营利组织。许多小额信贷机构以妇女为目标,因为贫穷的妇女多于男子,特别是在农村地区。研究表明,女性管理金钱的方式与男性不同,领导风格也不同。因此,在信用合作社和金融公司,女性和男性经理取得不同的结果。在小额信贷方面,小额信贷机构董事会的性别多样性是有益的,女性信贷员批准的贷款违约率较低。在这些发现的激励下,我们想知道,由女性担任首席执行官的小额信贷机构是否能更有效地为穷人服务,同时又不危及财务可持续性。我们根据管理效率调整银行方法,以考虑小额信贷机构的外联和可持续性目标,并评估小额信贷机构的外联效率是否因其各自首席执行官的性别而异。我们使用Battese-Coelli(1995)模型估计随机前沿成本函数,并使用来自250多个小额信贷机构的面板数据估计“真实”随机效应。我们发现女性ceo的小额信贷机构的外联效率显著高于男性ceo的小额信贷机构。用两步随机前沿法得到了类似的结果。总体而言,研究结果表明,在小额信贷机构的高层管理中促进性别多样性可能会带来社会和经济效益。

Investment in Cellulosic Biofuel Refineries: Do Waivable Biofuel Mandates Matter? 投资纤维素生物燃料精炼厂:可豁免的生物燃料法规重要吗?

We develop a conceptual model to study the impact of mandate policies on stimulating investment in cellulosic biofuel refineries. In a two-period framework, we compare the first-period investment level (FIL) under three scenarios: laissez-faire, non-waivable mandate (NWM) policy, and waivable mandate (WM) policy. Results show that when plant-level marginal costs are increasing then both NWM policy and WM policy may stimulate FIL. The WM policy has a smaller impact than does the NWM policy. When the plant-level marginal costs are constants, however, WM policy does not increase FIL but does increase the expected profit of more efficient investors.
我们开发了一个概念模型来研究授权政策对刺激纤维素生物燃料精炼厂投资的影响。在两期框架中,我们比较了三种情况下的第一期投资水平(FIL):自由放任、不可放弃的授权(NWM)政策和可放弃的授权(WM)政策。结果表明,当工厂边际成本增加时,NWM政策和WM政策都可以刺激FIL。WM策略的影响小于NWM策略。然而,当工厂边际成本为常数时,WM政策不会增加FIL,但会增加效率较高的投资者的预期利润。

This article is concerned with efficient estimation of characteristics demand. We derive and estimate an inverse input demand system for quality characteristics by using 172,946 observations over 881 trading days in the Icelandic fish auctions. An improved estimation method based on an expanded random coefficient model is suggested as an alternative to the currently used two-stage method of Brown and Rosen. The estimates demonstrate the improved efficiency of the suggested method. A number of empirical results emerge, including a general increase in the demand for quality.

The modeling of micro-level food demand patterns requires not only allowing for household heterogeneity, but also addressing the problem of censoring. In this article, we present a variation of the Amemiya-Tobin framework for estimating a censored demand system that allows for household heterogeneity. The unique aspect of our approach is the use of a procedure that ensures the adding up of both latent and observed expenditure shares and also imposes expenditure share nonnegativity. This system is applied to an analysis of food demand based on a random sample of urban Mexican households.
微观层面粮食需求模式的建模不仅需要考虑到家庭的异质性,而且还需要解决审查问题。在本文中,我们提出了阿米米亚-托宾框架的一种变体,用于估计允许家庭异质性的审查需求系统。我们方法的独特之处在于使用了一种程序,该程序确保了潜在和观察到的支出份额的总和,并规定了支出份额的非负性。该系统应用于基于墨西哥城市家庭随机样本的粮食需求分析。

Laws concerning government accountability mandate that agencies weigh constituent interests in setting priorities. This study extends literature on the value of research by considering the public's stated preferences for scientist-effort allocated across an Agricultural Experiment Station's research portfolio. Over 75% of respondents expressed a willingness-to-pay exceeding $20 per household for allocations of at least 139 scientist-months. The mean household is willing to pay about $25 for a 25% increase in effort. Marginal analysis identifies topic areas where an additional scientist-month provides above- or below-average benefits. The distribution of effort across research topics significantly affects respondents' values.

This article proposes a tractable approach for analyzing the sources of TFP changes (i.e., technical change, changes in technical and allocative inefficiency, and the scale effect) in a multi-output setting, while retaining the single-equation nature of the econometric procedure used to estimate the parameters of the underlying technology. The proposed approach relies on Bauer's cost function-based decomposition of TFP changes and the duality between input distance and cost functions. The empirical results are based on a sample of 121 UK livestock farms observed over the period 1983–92 and a translog input distance function. Copyright 2004, Oxford University Press.

Shared Agents and Competition in Laboratory English Auctions 实验室英语拍卖中的共享代理与竞争
Pub Date : 2003-11-01 DOI: 10.1111/1467-8276.00491
D. Menkhaus, Owen R. Phillips, Kalyn T. Coatney
At livestock auctions, the same purchasing agent can represent more than one processor. Repeated multiple-unit English auctions are created in a laboratory to measure the impact of shared agents on trade prices under alternative treatments with six, and as few as two, agents representing six principals. Treatments are constructed in which the agents either know or do not know quantity for sale, and in which there are progressively fewer agents bidding. Knowledge of quantity for sale can be anticompetitive. Evolution toward increased market concentration leads to consistent anticompetitive pricing, resulting in prices significantly lower than the predicted competitive equilibrium prices.
在牲畜拍卖中,同一个采购代理可以代表多个加工商。重复的多单元英语拍卖是在实验室中创建的,以衡量共享代理对交易价格的影响,这些代理有6个,少则2个,代表6个委托人。在处理过程中,代理商知道或不知道待售数量,并且竞标的代理商逐渐减少。对销售数量的了解可能是反竞争的。市场集中度的提高导致了持续的反竞争定价,导致价格显著低于预期的竞争均衡价格。

For risk-averting agents, risks alter production decisions while the existence of institutions to insure against adverse states of nature will likely restore decisions toward levels under risk neutrality. In this article, conditions are identified on a stochastic technology to test H rn 0,≤ : that risk averters choose smaller input levels than risk neutral agents, and H ra 0,≤ : that an increase in risk aversion reduces input use. A robust statistical method to test for dominance is adapted to stochastic production relations. It is found that H rn 0,≤ is likely true for nitrogen application on Iowa corn. Weaker evidence is found in favor of H ra 0,≤ . Copyright 2003, Oxford University Press.
对于风险规避主体,风险改变生产决策,而制度的存在,以确保对不利的自然状态将可能恢复决策到风险中立的水平。在本文中,在随机技术上确定了条件来检验hr0,≤:风险厌恶者选择比风险中立者更小的投入水平,以及hr0,≤:风险厌恶的增加减少了投入的使用。针对随机生产关系,提出了一种稳健的优势检验方法。结果表明,在爱荷华玉米上施氮,hrn 0,≤可能是正确的。较弱的证据支持hra 0,≤。牛津大学出版社版权所有。
