Access to markets,weather risk,and livestock production decisions: Evidence from Ethiopia

Despite several studies showing the effect of access to markets and weather conditions on crop production, we know quite little on whether and how livestock production systems respond to variation in weather risk and access to markets. In this paper, we study whether and how livestock production responds to (access to) markets and varying weather risk. We also explore whether such responses vary across livelihood zones and livestock production systems. We study these research questions using households’ livestock production, ownership, and marketing decisions of households in Ethiopia. We find that households living close to markets are more likely to engage in market-oriented livestock production and use modern livestock inputs. We also find that households exposed to more unpredictable weather are less likely to engage in livestock production for markets, rather they are more likely to engage in livestock production for precautionary savings and insurance. Furthermore, greater rainfall uncertainty influences livestock portfolio allocation toward those which can be easily liquidated while also discouraging investment in modern livestock inputs. However, these responses and patterns vary across livelihood zones and production systems; most of these stylized responses and impacts are more pronounced and significant in the arid and semi-arid lands of Ethiopia, where livestock herding remains a dominant source of livelihood. Those households relying only on livestock production seem more sensitive and responsive to weather risk and weather shocks. The heterogeneity in responses and impacts of weather risk among farming systems and livelihoods highlights the need for more tailored livestock sector policies and interventions.     

Effects of decoupling on the mean and variability of output

The influence of inputs on output risk in the context of agriculturalproduction decisions taken by non-risk neutral agents has beenignored by previous research assessing the effects of decoupledincome support payments in a deterministic world or risk-neutralframework. We study the impacts of decoupled payments on inputuse and on output mean and variance. Our theoretical frameworkfor studying agricultural producers' responses to lump sum paymentsallows for both output and price uncertainty and economic agents'risk attitudes. Results show the importance, in a non-risk neutralscenario, of considering the influence that economic agentshave on the stochastic component of output through input use.Our empirical application uses Kansas farm-level data to illustratethe model.     

Has China’s new round of collective forest reforms caused an increase in the use of productive forest inputs?

Forestland tenure and financial incentives are the most important policy issue to sustainable forest resource management. The new wave of reform of collective forestland tenure (NRCFT) has been launched since 2003 and the governmental matching reform measures (MRMs) for the NRCFT have been introduced since 2009. The objective of these reforms is to enhance sustainable forest resource management in Chinese collective regions by encouraging rural households’ productive forest inputs. We use a unique dataset of 1778 sample households in 18 counties of nine provinces with six years and employ a fixed effects model with clustered standard errors. Our empirical results indicate that: 1) the NRCFT has increased households’ forestland area of different tenure types, and the effects of the MRMs on rural households’ labor input and production expenditures for forestry purposes are generally positive, especially household used forestland as collateral for a loan and afforestation or reafforestation subsidy and reform of Annual Allowance Cut (AAC) have significantly contributed to increase in the use of productive forest inputs; 2) the NRCFT and the MRMs have different impacts on the use of productive forest inputs for different tenure forests, and these reforms have caused the most significant changes in rural households’ production decision changes for household responsibility forestland; 3) both the NRCFT and the MRMs have significant effects on rural households’ rent-in and rent-out forestland; and 4) forestland fragmentations have caused additional labor and investment inputs for rural households’ forest resource management and protection. And finally, market drivers and household and village characteristics factors also affect households’ decisions for productive inputs for their managing forests.     

Analysing Production Technology and Risk in Organic and Conventional Dutch Arable Farming using Panel Data

This paper compares the production technology and production risk of organic and conventional arable farms in the Netherlands. Just–Pope production functions that explicitly account for output variability are estimated using panel data of Dutch organic and conventional farms. Prior investigation of the data indicates that within variation of output is significantly higher for organic farms, indicating that organic farms face more output variation than conventional farms. The estimation results indicate that in both types of farms, unobserved farm‐specific factors like management skills and soil quality are important in explaining output variability and production risk. The results further indicate that land has the highest elasticity of production for both farm types. Labour and other variable inputs have significant production elasticities in the case of conventional farms and other variable inputs in the case of organic farms. Manure and fertilisers are risk‐increasing inputs on organic farms and risk‐reducing inputs on conventional farms. Other variable inputs and labour are risk increasing on both farm types; capital and land are risk‐reducing inputs.     

The effects of EU agricultural policy changes on farmers' risk attitudes

This analysis utilises a model of production under risk estimatedon Finnish farm-level data to measure farmers' risk attitudesin a changing policy environment. We find evidence of heterogeneousrisk preferences among farmers, as well as notable changes overtime in farmers' degree of risk aversion. This result is dueto the increase in the non-random part of farm income generatedby the policy change after Finland's European Union accession.The analysis confirms the assertion that agricultural policiesthat are decoupled from production do affect input use and cropmix through their effect on farmers' risk attitudes.     

Decoupled Agricultural Policy and the Lack of Production Alternatives

Overall, only a small proportion of geographic-specific production (for the selected commodities) are in areas that are highly specialized in that commodity. The large proportion of production in nonspecialized regions suggests that other production opportunities do exist. Thus, a “decoupled” agricultural policy would not necessarily mean that producers receiving a decoupled “government payment would be constrained by geographic factors to continue their original production pattern. We recognize, however, that others may wish to select different commodity groups when analyzing the availability of production alternatives. We suggest that census data do provide one way for determining the extent to which a decoupled” agricultural policy may in effect lock in the existing production pattern.     

Welfare implications of reduced government subsidies to farm families: accounting for fringe benefits

In the past three decades, farm families have relied on government payments and off‐farm income to reduce income risk and increase total household income. Studies have shown that, as the income effect dominates, government payments tend to reduce off‐farm labor of farm operators and spouses. But that may not be true if one accounts for fringe benefits associated with off‐farm employment. Additionally, with looming budget deficits and the possibility of a reduction in decoupled government payments, farm families may be facing an altered economic environment. Our study addresses this issue by examining the links between government farm program payments and the ever‐important role of fringe benefits in the off‐farm employment of farm couples. Results from farm‐level data actually show that the marginal effect of government payments on hours worked off‐farm will decrease in magnitude when accounting for fringe benefits, ceteris paribus. These results support the notion that farm households’ welfare loss stemming from reduced decoupled payments may be overstated when models exclude fringe benefits from the estimation of off‐farm labor supply.     

Investment rigidity and policy measures

This paper assesses the impacts of decoupled government transferson production decisions of a sample of Kansas farms. Our empiricalanalysis is based on a reduced-form application of the dualmodel of investment under uncertainty developed by Sckokai,which is extended to a consideration of irregularities in thecapital stock adjustment cost function. To do so we adopt thethreshold regression methods proposed by Hansen. The econometricresults support the existence of three regimes characterisedby different economic behaviour. Our analysis suggests thatin a dynamic setting that allows for irregularities in the capitaladjustment cost function, decoupled transfers can have a powerfulinfluence on production decisions. The dynamics of the stockof capital cause this influence to grow over time.     

Fungicide use under risk in Swiss wheat production

The short-run effects of fungicide application on economic risk and the effects of risk on fungicide use in Swiss wheat production are empirically explored. A quadratic production function model is developed. With the help of the moment-based approach, marginal contributions of fungicides (representing controlled inputs) and of rain (representing uncontrolled inputs) to the variances of yield and revenue are analyzed. It is not possible to show risk-reducing effects of fungicides on yield or revenue. At low rain quantities during the vegetation period fungicides have a statistically significant risk-increasing effect on revenue. Increasing risk leads Swiss wheat growers to use more fungicide. This increase is statistically significant at higher levels of revenue. For example, when risk is doubled fungicide inputs are raised by 44% at the highest revenue quartile.     

China’s Agricultural Policy Transition: Impacts of Recent Reforms and Future Scenarios

This article reviews recent developments in China’s agricultural domestic support policy, especially the transition from taxing farmers and agriculture to providing direct subsidies to grain production and purchased inputs. A model‐based quantitative analysis on the effects of these policy changes is presented. Simulation results suggest that recent policy changes have achieved the declared policy goals of increasing grain production and boosting farm income. Much of the increase in grain production and farm income can be attributed to higher per unit return to arable land, land reallocation to grain production and extra agricultural employment triggered by the policy changes. Based on the assumption that China’s public assistance to agriculture and farmers will continue and rise, two hypothetical future scenarios are simulated. Using all the support permitted under WTO de minimis limits with existing instruments, China’s policy will increase grain production, change trade patterns seemingly contrary to China’s comparative advantage, increase rural employment and significantly increase farm income (by more than 12%). If, however, decoupled instruments are applied to raise China’s agricultural domestic support to the same level, China’s agricultural production and trade will remain unchanged, rural employment remain stable, but farm income will be increased by nearly 15%.     

The Varying Impacts of Agricultural Support Programs on U.S. Farm Household Consumption

Farm households are economic agents whose income is derived from farm, off-farm, and government sources. This article uses farm-level data from the Agricultural Resource Management Survey (ARMS) and recent advances in the econometric theory of dynamic pseudo-panels to show that farm households consume various sources of income differently at the margin. Particular attention is given to a specific type of lump-sum government transfer payment intended to be decoupled from (independent of) farm production decisions. The results suggest that relatively decoupled government subsidies have a greater marginal effect on farm household consumption than subsidies that are tied to market conditions.     

Economic and environmental effects of decoupled agricultural support in the EU

This article reports findings from a simulation model representing the European farming system disaggregated at different scales. This modeling experiment explores the effects of various decoupling options associated with the 2003 European agreement on gross margins, land use, shadow cost of land, and greenhouse gas emissions. Our results show increases in the farmers’ gross margins when decoupled support is maintained equal to the amount of direct aid previously attributed to agricultural production, assuming unchanged prices. Land used for pasture increases at the expense of land used for cereals and protein crops. The extent to which these effects materialize depends on the policy options selected by Member States when implementing the Luxembourg agreement. When they opt for some recoupling of support, adverse net economic impacts occur for producers. Regional differences in impacts are more pronounced than the analysis aggregated at European and national scales suggests. This highlights the need for further work based on geostatistical downscaling.     

Adaptive society in a changing environment: Insight into the social resilience of a rural region of Taiwan

Taiwan has abundant biological resources that provide a quality living environment; however, industrial land use may change that environment through urban sprawl and thus have impacts on rural society. This study examined the experience of a Taiwanese rural region that has been exposed to industrial wastewater discharge specifying the relationship of industrial development to rural society and its role in policy. We addressed the societal adaptation to environmental degradation from risk perception perspectives about land use. Drawing on social vulnerability concept, semi-structured interviews were conducted in five communities that use irrigation water exposed to wastewater discharge. The interviews were designed using the Driver-Pressure-State-Impact-Response (DPSIR) causal framework to examine residents’ risk perceptions highlighting both built-environmental sensitivity (degradation) and residents’ adaptability (capacity). In addition, remote sensing technology was used to identify the urban sprawl that led to industrial land use and exposed the rural region to water pollution risks. As a result, we present a social resilience cycle to introduce adaptive responses underlining social amplification of risk. Both local knowledge of the locals (the Hakka people) and their societal response to environmental change reflect the role of culture in influencing land use policy. It is underlined that individual and community responses shape the social experience of risk and are related to both the ethnicity of the locals and the land use policy of the government. We indicated further that a large-scale survey that would really quantity this exploratory study to support land use decision-making is expected.     

Factors influencing technological practices in the Brazilian agrarian reform

In recent decades, agriculture has responded to technology-related changes with strong productivity growth. Despite this evolution, the adoption of new technologies by small farmers has been a consistent challenge. In the coming years, the adoption of technology should be an essential element for the survival of small producers. To follow this evolution, the objective of this research is to identify factors that influence the adoption of higher levels of technological practices by producers of the agrarian reform in the Midwestern region of Brazil. Technological practices were evaluated based on the adoption of natural or chemical inputs, crop rotation, high yield seeds and mechanization. Higher levels of technological practices were defined as the joint use of these technologies, classified as technological packages. We identified two technological packages, one using natural inputs and the other chemical inputs. Questionnaires were applied to 1,162 settlers and the analytical model used was an ordered logit. Education, technical assistance and exchange experience with neighbors have a positive effect on technology use but do not favor the use of technological packages, which are instead favored by training courses in technology, partnerships with agro-food companies and resources available for investment. Thus, the government’s priority should be to offer good technical support and access to training courses in technology. The financing of production costs did not show any effect on the adoption of technology, in contrast to funding for investments. Consequently, the financing of production costs should be reconsidered to favor greater technological investments.     

How Decoupled are Decoupled Payments? The Evidence from Ireland

This article explores the production effects of the EU's system of decoupled payments and the implications for WTO negotiations. We compare survey data on Irish farmers' production plans post decoupling to the optimal outputs predicted by a farm-level profit maximisation model. The results show that, post decoupling, a significant number of farmers plan to use their decoupled payments to continue or expand economically non-viable production. An econometric analysis reveals that the decision to maintain or expand production levels post decoupling is not significantly influenced by current or future projected profitability levels. The analysis suggests likely widespread cross subsidisation of unprofitable production post decoupling but that aggregate production is still likely to decline relative to the traditional coupled, but production-limiting, blue box payments. If the EU wants to claim in the current WTO negotiations that decoupled payments amount to green box support, then the argument must be made that the payments have no, or at most minimal, trade distorting effects or effects on production. If it becomes apparent to members of the WTO that European farmers are using their decoupled income to subsidise market loss production, then the green boxing of the EU's decoupled payment scheme may come up for debate at the negotiations.     

Short‐ and Long‐Run Policy Evaluation: Support for Grassland‐Based Milk Production in Switzerland

Following the abolition of the milk quota in 2008, farmers in Switzerland strongly increased the use of concentrate feed in milk production. Against this background, the Swiss government introduced the voluntary grassland‐based milk and meat (GMF) programme in 2014, which combines economic incentives with feeding restrictions to reduce the reliance on concentrate feed and increase the use of grass feed. We analyse the economic and ecological impacts of the GMF programme at the farm and at the sector level in the short‐ and long‐run. We use a difference‐in‐differences approach (ex‐post) and an agent‐based simulation model SWISSland (ex‐ante) to construct counterfactual states to evaluate the programme's impacts. We find that the GMF programme reduces the use of concentrate feed and increases the use of grass feed in Swiss milk production. Whereas the programme has a positive effect on economic indicators such as the farm income, we find no effect on ecological indicators such as the N surplus. Our analysis suggests that feeding restrictions on concentrate feed are not enough to achieve a reduction in the N surplus. Additional feeding restrictions on grassland are necessary. Furthermore, the GMF programme has a dampening effect on sectoral milk supply, and leads to a higher milk price.     

Agriculture and climate change in global scenarios: why don't the models agree

Agriculture is unique among economic sectors in the nature of impacts from climate change. The production activity that transforms inputs into agricultural outputs involves direct use of weather inputs (temperature, solar radiation available to the plant, and precipitation). Previous studies of the impacts of climate change on agriculture have reported substantial differences in outcomes such as prices, production, and trade arising from differences in model inputs and model specification. This article presents climate change results and underlying determinants from a model comparison exercise with 10 of the leading global economic models that include significant representation of agriculture. By harmonizing key drivers that include climate change effects, differences in model outcomes were reduced. The particular choice of climate change drivers for this comparison activity results in large and negative productivity effects. All models respond with higher prices. Producer behavior differs by model with some emphasizing area response and others yield response. Demand response is least important. The differences reflect both differences in model specification and perspectives on the future. The results from this study highlight the need to more fully compare the deep model parameters, to generate a call for a combination of econometric and validation studies to narrow the degree of uncertainty and variability in these parameters and to move to Monte Carlo type simulations to better map the contours of economic uncertainty.     

Off‐farm employment and reasons for entering farming as determinants of production enterprise selection in US agriculture

In today’s agriculture, farmers consider off‐farm employment and lifestyle goals in complex ways to select production enterprises. Data from USDA’s Agricultural Resource Management Survey were used to examine how off‐farm employment and ‘reasons for entering farming’ influence production enterprise selection in US agriculture. A two‐stage analysis with a multivariate tobit model was used to examine the impact of off‐farm employment as influenced by government farm programme payments, reasons for entering farming, demographics and location on production enterprise selection. Results underscore the impacts of reasons for entering farming and off‐farm employment on production enterprise choice and provide implications for policy development. The study highlights the importance of government farm programme payments in production enterprise selection by US farmers.     

Factors influencing the profitability of fertilizer use on maize in Zambia

Fertilizer use remains very low in most of Africa despite widespread agreement that much higher use rates are required for sustained agricultural productivity growth. This study uses longitudinal farm survey data to estimate maize yield response functions in a relatively high-potential zone of Zambia to determine the profitability of fertilizer use under a range of small-farm conditions found within this zone. The theoretical framework used in this study incorporates agronomic principles of the crop growth process. We generalize the asymmetric production models and define a concept of yield scaling factors. The model distinguishes different roles of inputs and non-input factors in crop production. We estimate the effects of conventional production inputs as well as of household characteristics and government programs on maize yield. The results indicate that recommended fertilizer application rates in the two specific years were often unprofitable, given observed price conditions and the yield response to fertilizer. However, there was substantial variability in yield response to fertilizer based upon the rate of application, the timeliness of fertilizer availability, the use of animal draught power during land preparation, and whether the household incurred the death of an adult member in the past three years. These modifying factors, as well as variations in input and output prices due to proximity to roads and markets, substantially affected the profitability of fertilizer use on maize.     

Estimation of input-oriented technical efficiency using a nonhomogeneous stochastic production frontier model

Technical inefficiency can be modeled as either input‐oriented (IO) or output‐oriented (OO). However, in the estimation of parametric stochastic production frontier models which use maximum likelihood method only the OO measure is used. In this article we consider a simple nonhomogeneous production function and estimate it with both IO and OO specifications. A sample of 80 Spanish dairy data (1993–1998) is used to estimate both models. We consider one output (liters of milk) and four variable inputs (viz., number of cows, kilograms of concentrates, hectares of land, and labor [measured in man‐equivalent units]). We find that returns to scale (RTS) and technical efficiency results derived from these models are different because either estimated technologies are different, or they are evaluated at different points. Using a Monte Carlo analysis we show that if RTS is close to unity differences in the estimates of RTS and technical efficiency are smaller. This holds true for estimates of both RTS and technical efficiency.
