Transaction cost theory and application tells us that when buyers and sellers in a market incur transaction costs, intermediaries may become involved. Specifically, intermediaries influence the cause of the transaction costs to buyers and sellers such that transaction costs are reduced. In this paper we assess if and how this occurs for a number of case study government created and private emergent intermediaries in Australian environmental offset markets. We find that the causes of transaction costs to buyers and sellers in offset markets – asset specificity, uncertainty and transaction frequency are influenced downwards by intermediaries. The degree of influence depends on the nature of the good traded in the offset market. We also assessed if the public intermediaries studied were operating in the offset markets to reduce the incidence of probity hazard (poor transactions) from private intermediaries. We found that this was not the case.  相似文献

Increased reliance on commercial traders in liberalised agricultural markets poses questions about the nature of contractual relations between traders and farmers; about welfare, efficiency and equity characteristics of these relations; and about conditions necessary for traders to engage in these markets. A new institutional economics analysis seeks to understand the institutions that affect transaction costs and risks for each party, and power relations between them. Transaction cost analysis has not, however, developed a unifying conceptual or quantitative framework to integrate these issues. This paper develops a methodology for modelling negotiated choice of contractual arrangements in buyer/seller relationships, taking account of the socioeconomic characteristics of each party, economic and technical characteristics of the commodity, and the institutional environment. The model is setup as a non‐linear programming problem. The approach provides a framework for the application of transaction cost economics to quantitative empirical study of markets, to individual firms' supply chain decisions, and to the analysis of policy interventions in markets.  相似文献

The paper looks at the possibility of creating a market for environmental goods and services in the countryside by awarding conservation contracts to farmers on the basis of competitive bidding. Auctions have several theoretical advantages over alternative allocation mechanisms (such as standard-rate payments) because they allow the participants to deal with informational asymmetries and the uncertainty about the value of the (non-market) goods being traded. A formal model of bidding behaviour in ‘green auctions’ shows that bidding strategies are determined by the individual farmers' costs of implementing the conservation contracts and their beliefs about the maximum acceptable payment level, making the auction an imperfect cost revelation mechanism. Auctions can reduce the information rents accruing to farmers and can increase the cost-effectiveness of public goods provision. Strategic bidding behaviour in multiple-signup auctions as well as high transaction costs are potential sources of reduced efficiency.  相似文献

ABSTRACT

The projected global expansion in consumption of meat and other livestock products potentially offers sub-Saharan African small-holder farmers opportunities to escape from the poverty trap. A necessary condition for exploiting this potential is the establishment of marketing systems that provide farmers with reasonable incentives to participate in the market. In this study, the functioning of livestock markets in rural Uganda is analyzed based on a survey of 401 livestock keepers, complimented with focus group discussions with livestock traders and policy planners. The first part is dedicated to the empirical analysis of key organizational and institutional arrangements. Constraints along the marketing chain as well as potential institutional solutions are illuminated. The second part is dedicated to propositions of new areas where more work and new results are needed to improve the functioning of the livestock marketing chain. Empirical findings indicated the following institutional constraints: a poor market information system, lack of grades and standards, lack of trade finance, poor contract enforcement and dispute settlement, disorganized actors, high transaction risks, and poorly developed marketing infrastructure. The study recommends a structured approach to livestock marketing, market infrastructure development, and emphasis on arbitration systems as specific ways of improving the efficiency of livestock marketing in Uganda and other developing countries.  相似文献

This article analyzes the impact of road rehabilitation on the spatial market efficiency of maize markets in Mozambique. We estimate a modified version of the Parity Bounds Model (PBM) that allows us to test the impact of road rehabilitation on spatial efficiency. This article seeks to contribute to the existing literature in three ways. First, a unique data set, where road rehabilitation episodes between market pairs are identified, is developed. Second, special care is devoted to estimation of transaction costs due to the sensitivity of the PBM model to the quality of transaction costs estimates. Finally, as opposed to most existing literature that focuses on relatively distant markets, the article focuses on spatially closed markets. We find that maize markets tend to be segmented due to high transport costs. Following road rehabilitation, inefficiency and average absolute price differentials tend to decrease, and market pairs have tended to shift toward autarky regimes. Overall, while the results point broadly toward a positive impact of road rehabilitation on spatial efficiency, they are not as strong or as robust as one would like. Large increases in fuel prices likely offset the positive impacts of road rehabilitation on transaction costs, contributing to the increase in the probability of being in an autarky regime.  相似文献

Abstract

Maize is Zimbabwe's staple food. An adequate supply of maize is essential to food security and domestic stability. A series of droughts and government mismanagement of the economy led to a maize production and food security problem in the 1980s. Zimbabwe's maize marketing system was transformed dramatically from a government monopoly to a competitive market system in which prices are determined by market forces in the 1990s. This paper examines the steps that Zimbabwe took towards maize market reform and the benefits of that reform. The movement to a competitive market led to formation of a commodity exchange to improve price discovery and increase price transparency. De-regulation has increased entry and competitiveness from new private sector hammer millers and traders. Farmers, millers, and traders face new profit opportunities and new price and financial risks that have increased management responsibilities. Consumers enjoy lower cost maize meal products and more convenient service. The benefits of the 1991–1997 reforms indicate what could be achieved in the long run if prices are determined by the market, rather than by the government.  相似文献

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。  相似文献

Data from a 1998 survey of farming households in Kenya is used to estimate the effects of poor rural road infrastructure (and high market access costs) on the structure of smallholder farm production. Simultaneous estimation of cost and input share equations reveals rational responses by farmers to high access costs. In the expected continued absence of major investments in rural infrastructure in countries such as Kenya, the policy challenge is to identify and catalyse institutional innovations that reduce a range of transaction costs, increase financial liquidity, increase social capital, and reduce risk.  相似文献

Farm incomes in rural Vietnam are tightly constrained by very small farm sizes. Stringent limits on the area of cropland that individuals may own means that farmers need a well‐functioning rental market to consolidate land parcels, grow their farm enterprises, adopt new technology and increase incomes. This research investigates the efficiency and equity impacts of the rental market in rural Vietnam and attempts to identify transaction costs impeding the market. A generalised ordered logit model with shifting thresholds allowing transaction costs to impact lessors and lessees differently was specified and estimated using data extracted from the Vietnam Household Living Standards Surveys. The findings show that rental transactions reduced imbalances in factor endowments, transferring cropland to households that were relatively land‐poor but more willing and able to farm. However, the market is constrained by transaction costs that affect lessors and lessees differently. It is recommended that government should complete its land registration program and relax restrictions on the use of wetlands to grow crops other than rice. It should also improve access to all‐weather roads as this encourages participation on both sides of the rental market, whereas better access to communications infrastructure was found to promote only the supply side.  相似文献

Using trimonthly Chinese provincial grain prices from 1988 to 1995, we estimate a parity-bounds model of interregional trade for four subperiods to characterize how multiple aspects of market performance change during the process of economic transition. For each period, we estimate the extent to which arbitrage opportunities are realized by traders, the transaction costs between location pairs, and the likelihood that regions do not trade. Trade restrictions cannot explain the pattern of uneven market development over time. Infrastructure bottlenecks, managerial incentive reforms, and production specialization policies, all were likely important factors affecting market performance.  相似文献

The article presents a theory of policy timing that relies on uncertainty and transaction costs to explain the optimal timing and duration of policy reforms. Delaying reforms resolves some uncertainty by gaining valuable information and saves transaction costs. Implementing reforms without waiting increases welfare by adjusting domestic policies to changed market parameters. Optimal policy timing is found by balancing the trade‐off between delaying reforms and implementing reforms without waiting. Our theory offers an explanation of why countries differ with respect to the length of their policy reforms and why applied studies often judge agricultural policies to be inefficient when actually they may not be.  相似文献

Hedging Multiple Price Uncertainty in International Grain Trade   总被引:3,自引:0,他引:3  
Commodity and freight futures contracts are analyzed for their effectiveness in reducing uncertainty for international traders. A theoretical model is developed for a trader exposed to several types of risk. OLS hedge ratio estimation is compared to the SUR and the multivariate GARCH methodologies. Explicit modeling of the time-variation in hedge ratios via the multivariate GARCH methodology, using all derivatives, and taking into account dependencies between prices, results in reductions in risk, even after accounting for transaction costs. Results confirm that while the commodity futures contracts are important for hedging risk, freight futures are a useful mechanism for reducing risk.  相似文献

Increases in U.S. consumer incomes result in an increase in imports' share of U.S. consumption. Although U.S. consumers reduce the quantity demanded in response to higher import prices, the reduction is sufficiently inelastic that exporter revenue increases. U.S. Free Trade Agreements have made fresh fruits and vegetables available throughout the year and may also have broadened the U.S. marketing window for imports. Now U.S. food safety regulations favor large operations that can absorb the fixed and seasonal food safety related costs. Therefore, the brunt of the increased import competition is borne by small and medium-size producers.  相似文献

Farmers in sub‐Saharan Africa are constrained by large transaction costs associated with marketing of their livestock. However, transaction costs are often not taken into account in the analysis of factors hampering the development of livestock marketing in this region. This article empirically measures the influence of transaction costs on the offtake from cattle grazed on natural rangelands in Uganda. The study is based on the monitoring of 696 cattle transactions in three districts of Uganda from August 2004 to August 2005. The estimated models suggest that proportional transaction costs represented by the state of roads, distance to markets, and time taken to reach the market are important variables constraining market participation. In order to raise offtake from the national herd, it is essential to explicitly address these costs. One potential solution is collective action in marketing of livestock in which proportional and fixed transaction costs are reduced and shared among the group members.  相似文献

集体经营性建设用地统筹入市的模式选择   总被引:1,自引:0,他引:1  
研究目的:比较分析两种集体经营性建设用地统筹入市模式的治理效率,为深化集体经营性建设用地市场化治理实践提供参考。研究方法:基于案例的交易成本比较分析。研究结果:不确定性是影响统筹入市模式选择的关键因素。村集体自组织的土地联营公司模式比政府主导的土地整备模式,更适于处理较高不确定性引致的交易成本,在促成集体行动、避免事后违反协议、促进收益分配公平等方面表现更好。研究结论:集体经营性建设用地入市的交易属性与所采用的治理模式之间的匹配程度决定统筹入市的治理效率。建议在农村经济较为发达的地区,发挥政府协调引导作用,鼓励各村集体在充分协商的基础上,成立联合委员会或者土地股份公司,合作开展集体经营性建设用地的统筹入市。  相似文献

Value chains linked to urban markets and agro-industry present new opportunities for adding value and raising rural incomes. Small farmers, who produce small volumes, struggle to enter these markets. A lack of trust among value chain actors increases transaction costs and short-circuits innovation. This paper explores how multi-stakeholder platforms have been used to address these problems in potato-based value chains in Bolivia, Peru and Ecuador. It uses the Institutional Analysis and Development (IAD) framework to understand how platforms work. Differences in characteristics of the value chains, the participating actors and institutional arrangements have led to the emergence of two types of platforms. The first type brings traders, processors, supermarkets and others together with farmer associations and research and development (R&D) organizations to foster the development of new market opportunities through commercial, institutional and technological innovation. The second type is structured around geographically delimited supply areas, meshing farmers and service providers to address market governance issues in assuring volumes, meeting quality and timeliness constraints and empowering farmers. Evidence from these cases indicates that platforms that bring stakeholders together around value chains can result in new products, processes, norms and behaviours that benefit poor farmers, which could not have been achieved otherwise.  相似文献
