The promise (and pitfalls) of ICT for agriculture initiatives

The widespread growth of information and telecommunication technologies (ICTs) in rural areas of developing countries offers new opportunities to provide more timely and low‐cost information services to farmers, as well as assist in coordinating agricultural agents. Over the past decade, the number of public and private sector initiatives in this space has increased substantially, with over 140 deployments worldwide in 2015. While there is substantial potential for such services to address farmers’ and traders’ information and credit market constraints, economic research suggests that the impacts of such services on agricultural adoption, behavior and welfare is mixed. While this can, in part, be explained by the degree of the information asymmetry and the presence of other market failures in different contexts, research from other disciplines provides additional insights into these findings. In particular, work in the domain of human–computer interaction (HCI) focuses heavily on users’ interaction and experience with a given technology, thus explaining why users may not fully engage with ICT‐based agricultural interfaces. Furthermore, sociological and anthropological approaches study the provision of information and trust and how these may be altered by ICT platforms. Drawing upon these disciplines, we suggest that future ICT for agriculture initiatives should first seek to better understand the information and complementary market failures in a given context, in order to better understand whether information is a binding constraint. Second, even if information is missing, the information services provided should be of high quality and from a trusted source, which can be a challenge with some ICT platforms. Finally, such services should be delivered via platforms that build upon local ICT access and usage, paying particular attention to the gender digital divide.     

The impact of farm credit in Pakistan

Both informal and formal loans matter in agriculture. However, formal lenders provide many more production loans than informal lenders, often at a cost (mostly loan default cost) higher than what they can recover. For example, the Agricultural Development Bank of Pakistan (ADBP), providing about 90% of formal loans in rural areas, incurs high loan default costs. Yet, like other governments, the Government of Pakistan supports the formal scheme on the grounds that lending to agriculture is a high risk activity because of covariate risk. Hence, such policies are often based on a market failure argument. As farm credit schemes are subsidised, policy makers must know if these schemes are worth supporting. Using a recent large household survey data from rural Pakistan (Rural Financial Market Studies or RFMS), we have attempted to estimate the effectiveness of the ADBP as a credit delivery institution. A two‐stage method that takes the endogeneity of borrowing into account is used to estimate credit impact. Results reveal that ADBP contributes to household welfare and that its impact is higher for smallholders than for large holders. Nevertheless, large holders receive the bulk of ADBP finance. The ADBP is, thus, not a cost‐effective institution in delivering rural finance. Its cost‐effectiveness can be improved by reducing its loan default cost and partially by targeting smallholders in agriculture where credit yields better results.     

Land degradation, drought and food security in a less-favoured area in the Ethiopian highlands: a bio-economic model with market imperfections

This paper presents a bio‐economic model of Andit Tid, a severely degraded crop‐livestock farming system with high population density and good market access in the highlands of Ethiopia. Land degradation, population growth, stagnant technology, and drought threaten food security in the area. Drought or weather risk appears to have increased in recent years. The bio‐economic model is used to analyse the combined effects of land degradation, population growth, market imperfections and increased risk of drought on household production, welfare and food security. We find that the indirect effects of drought on household welfare through the impact on crop and livestock prices are larger than the direct production effects of drought. Provision and adoption of credit for fertiliser, although risky in itself, may lead to increased grain production and improved household welfare and food security. Provision of credit may have a negative effect on conservation incentives but this effect may be mitigated by linking a conservation requirement to the provision of credit for fertiliser.     

Rational But Poor? An Explanation for Rural Economic Livelihood Strategy

Using panel data for six rural sub‐Saharan Africa countries, this article tests two hypotheses: (i) household‐specific staple food price bands resulting from market failures in the presence of liquidity constraints and rainfed agriculture induces rural household specialisation in food crops as an economic livelihood strategy; (ii) specialisation in food crops yields inferior welfare than diversification, and keeps households trapped in poverty. The results lend strong support to both hypotheses, reinforcing the need for public investment in rural infrastructure in order to encourage household livelihood diversification for improved welfare.     

The Farm Credit System as a Government-Sponsored Enterprise

This article examines the impact of government-sponsored enterprise status for the Farm Credit System on allocative efficiency in agricultural credit markets. The Farm Credit System was established originally to overcome market failures in these markets and to provide long-term funding at rates lower than private credit sources. Using a supply and demand model and an options model, the impact of subsidized interest rates is discussed. My results show that the default risk premium in interest rates is transferred from agricultural borrowers to taxpayers. There is evidence of deadweight losses and market distortions due to government-sponsored enterprise status for the Farm Credit System.     

Vertical integration in West Africa's cotton industry: are parastatals a second best solution?

This article provides a framework to compare market outcomes among vertically integrated monopsonies in the cotton sector of West Africa and alternative, more competitive market structures. Based on a principal agent framework, in the presence of factor market constraints, as well as capital market failure, efficiently operated cotton parastatals increase sector welfare and efficiency by providing input credits. In equilibrium, outcomes with the principal agent model suggest growers receive the reservation income to participate in cotton production while the principal (cotton company) extracts the surplus above the reservation income. Competitive markets entail more equitable distribution of benefits than with parastatal vertical integration, but credit and factor market constraints can still persist. Promotion of a competitive market system will not support cotton productivity growth unless stakeholders pursue complementary programs to develop credit markets and research and extension institutions. In the presence of current market failures, parastatals may be a second‐best solution.

Do Futures Benefit Farmers?

Simulations are used to analyze welfare and market- and farm-level effects of making futures available to producers of a storable commodity. Key features of the model are the explicit consideration of dynamic impacts due to inventories, and of aggregate market effects associated with futures adoption by some producers. Application to the natural rubber market shows that futures availability can lead to sizable market- and farm-level effects. Futures availability enhances consumer welfare, reduces nonadopter welfare, and yields important welfare gains for adopters when their market share is small and welfare losses when they account for a sufficiently large market share.     

The importance of the savings device in precautionary savings: Empirical evidence from rural Bangladesh

We test if precautionary behavior in the consumption decisions of rural households differs across the forms of savings. Using monthly panel data from Bangladesh, we find that, on average, the savings device does not matter but that the effect of income on savings indeed depends on the savings device. Precautionary savings in the form of staple grain are relatively constant across income quartiles, while nongrain precautionary savings vary across income quartiles. Previous studies, which treat these two types of savings devices as fungible, misdiagnose the reasons for, and by extension the market failures behind, a large percentage of the precautionary savings held by rural households.     

Rising Food Prices and Household Welfare: Evidence from Brazil in 2008

Food price inflation in Brazil in the 12 months to June 2008 was 18%, whereas overall inflation was 7%. Using spatially disaggregated monthly data on consumer prices and two different household surveys, we estimate the welfare consequences of these food price increases, and their distribution across households. Because Brazil is a large food producer, with a predominantly wage‐earning agricultural labour force, our estimates include general equilibrium effects on market and transfer incomes, as well as the standard estimates of changes in consumer surplus. Although the expenditure (or consumer surplus) effects were large, negative and markedly regressive everywhere, estimates of the market‐income effect were positive and progressive, particularly in rural areas. Because of this effect on the rural poor, and of the partial protection afforded by increases in two large social assistance benefits, the overall impact of higher food prices in Brazil was U‐shaped, with middle‐income groups suffering larger proportional losses than the very poor. Nevertheless, as Brazil is 80% urban, higher food prices still led to a greater incidence and depth of poverty at the national level.     

The effects of a large discrete maize price increase on the distribution of household welfare and poverty in rural Kenya1

This study estimates the effects of a large discrete maize price increase on the welfare of a sample of rural Kenyan households. The usual first‐order welfare approximation formula is extended to a second‐order formula that allows for supply and demand responses to the price change. Results show that many rural households are not affected greatly by the price change, and there are about as many gainers as losers. However, these full sample results mask important differences across regions. Welfare gains generally take place in major production areas while losses are in areas where most households are net buyers of maize. Semiparametric methods are used to investigate the relationship between income and the size of the welfare effect, and poverty dominance techniques are applied to study the impacts of the maize price increase on rural poverty.     

农户贷款利率改革的福利分析——以江苏、河南与甘肃农村信用社为例

本文以江苏、河南和甘肃农村信用社为例,采用条件价值评估法(CVM)获取各地农户微观数据,探讨放开农户贷款利率对不同地区农户经济福利的影响。研究表明,如果农村信用社放开农户贷款利率,各地农户经济福利变动将有显著差异:在江苏为负,在河南与甘肃为正,即放开农户贷款利率不会增进所有农民的福利。从增进农户福利的政策目标出发,农村金融机构改革应因地制宜。结合地区特征和农村金融机构服务半径等因素来探讨某地是否适合进行利率改革也许更有意义。     

Long-term consequences of short-term precipitation shocks: evidence from Brazilian migrant households

We find that large short-term precipitation shocks damage the long-term income of households that have permanently migrated from rural to urban areas. This outcome is consistent with the behavior of credit-constrained rural households who are willing to accept lower long-term income in urban areas following the depletion of their productive assets during an adverse shock. Our empirical evidence suggests that there may be a link between large precipitation shocks in rural areas and urban poverty. Further exploration is warranted on the mechanisms by which natural disasters cause these long-term losses.     

Assessing the effectiveness of rural credit policy on the adoption of integrated crop-livestock systems in Brazil

This study analyzes the effectiveness of rural credit policy to increase the adoption of ICLS. Analyzes are based on a survey with 175 farmers in the State of São Paulo, Brazil. Our estimates suggest that rural credit has positive and relevant impacts on the adoption of ICLS. In turn, the adoption of these systems may also involve investments in fixed capital and increases in operational costs, which create additional demand for rural credit. Other factors, such as access to extension policy, production scale, ex-ante perceptions, and market infrastructure also explain ICLS adoption. The access to rural credit policy is also determined by dependence on farm income, farmer’s perception of transaction costs, and supply of credit in the municipality. The study finally discusses important implications for the devising of rural credit policies and the diffusion of sustainable production systems in developing countries.

FOOD SECURITY IN KWAZULU: RESULTS OF A HOUSEHOLD-BASED PROGRAMMING MODEL

A mathematical programming model of rural KwaZulu, excluding three northern districts, was developed to simulate agricultural production in regions of high and low cropping potential. This model aggregates enterprise levels predicted for four representative households of which two are in the high-potential region and two in the low-potential region. Several economic scenarios are simulated with the model to predict, inter alia, responses to changes in cereal prices, input subsidies, changes in off-farm employment and a rental market for crop land. Long-run food supply response is estimated to be inelastic with respect to changes in product and input prices. Higher food prices harm the majority of rural households. Lower input prices have little impact on household welfare. Conversely, it is predicted that a rental market for arable land could have a large positive impact on crop production and would improve household welfare.     

The producer welfare effects of trade liberalization when goods are perishable and habit‐forming: the case of asparagus

Asparagus is a perishable, highly seasonal crop. We find that out‐of‐season imports of asparagus caused habit formation that increased demand in the U.S. growing seasons. We find that habit effects offset about 64% of the welfare losses to U.S. asparagus producers from increased Mexican imports under NAFTA and all of the U.S. producer welfare losses from increased Peruvian imports under the Andean Trade Preference Act. We estimate that the U.S. producer welfare losses from NAFTA are less than the annualized value of market loss assistance provided them in the 2008 Farm Bill.

农村商业银行在提供金融服务的同时,也面临来自借款人层面的信贷风险。而这种信贷风险的产生源于信贷市场中的信息不对称、有限理性和羊群效应等。文章利用层次分析法,从借款人角度构建农村商业银行信贷风险的预警体系,设计农村商业银行信贷风险的控制策略。并用江苏省10家农村商业银行2018年的数据进行验证,研究结论显示:个别农商行的信贷风险水平较高,在经济下行期,且有向高风险发展的趋势,建议从构建风险预警体系、完善内部控制建设等方面加强重视和防范。     

Markets and pro-poor agricultural growth: insights from livelihood and informal rural economy models in Malawi

This article presents the development of a set of programming models describing the major features of different rural livelihoods and of the informal rural economy they together make up in Malawi. The models allow for differentiated responses by different household types to change and for the partial equilibrium effects of consequent supply, demand, and price adjustments in labor and grain markets. The models provide insights into the relations between own‐farm and nonown‐farm activities in different households' livelihoods and in the informal rural economy as a whole, and are used to investigate possible impacts of increasing cash crop prices and of a more open rural economy. Impacts of these changes on the poor are found to be critically dependent upon supply and demand elasticities in labor and grain markets, but the poor could potentially suffer significant losses from increased openness of the local economy leading to increased expenditure by less poor households on imported goods and services.     

Rural Banking and Landless Labour Households: Institutional Reform and Rural Credit Markets in India

Financial liberalization is a key component of programmes of orthodox structural adjustment. Financial reforms include, among other things, the removal of controls on interest rates and the abolition of programmes of directed credit. Here the effect of financial sector reform on rural banking and rural credit transactions in India is examined, with particular reference to landless labour households. First, the trends in selected indicators of rural banking at the national level over the last 30 years are reviewed. Secondly, longitudinal data for a village in Tamil Nadu are used to examine changes in patterns of indebtedness and credit transactions among landless labour households. It is argued that the exploitation of landless labour households in the credit market has intensified with the introduction of financial reforms. Lastly, the policy envisaged as an alternative to the formal credit sector in the countryside – the establishment of micro–credit projects – is examined critically.
