Access to a Telephone and Factor Market Participation of Rural Households in Bangladesh

This paper assesses the impact of access to a telephone on rural households’ factor market opportunities. It answers two questions. First, does the use of a telephone have any impact on rural households’ factor market participation? Second, correcting for market participation, does the use of a telephone have any impact on the type of factor market participation? For the first question, the paper uses a bivariate probit to correct for omitted variable bias and for the second question, the paper uses a two‐stage probit. The empirical findings suggest that access to a telephone has a significant positive impact on factor market participation. The difference in market participation between telephone users and non‐users is around 14%. However, once a household participates in the market, the use of a telephone does not have any impact on specific factor market participation.     

Farm-gate tomato price negotiations under asymmetric information

This article provides an empirical analysis of farm‐gate tomato price negotiations under asymmetric information. Regression models are estimated to analyze when and by how much sellers stick to their initial ask prices and what explains the variation in the initial ask–offer price spread. Detailed information on 66 farm‐gate tomato transactions and daily tomato wholesale price data from the central vegetable market in Addis Ababa are used for the analysis. Estimation results show that farmers are less committed to their initial ask price when the buyer speaks out the transaction price first, when their quality perceptions of the tomatoes being transacted differ from those of the buyers, and when their tomato farm is at a large distance from the main road. Sellers stick more to their initial ask price when they know that the central market price is high. The initial ask–offer price spread decreases when the buyer speaks out the initial negotiation price first, but increases in the difference in quality perception between buyer and seller, and in the quantity of tomatoes being transacted.     

Impacts of price and productivity changes on banana‐growing households in Uganda

This article compares the effects of changing market prices and farm productivity on the welfare of banana‐growing households in the Ntungamo district of Uganda. A heterogeneous‐agent model is applied via a series of mathematical optimization problems, to simulate production and consumption responses of 70 farm households surveyed in 2006. Results show that a given increase in productivity has a greater impact on poverty alleviation than that same increase in market prices. Despite the effects of productivity gains being comparable across different types of household groups, price improvements primarily benefit the incomes of households who are involved in rural producer organizations, who are located closer to markets, and who sell at the market.     

Market imperfections,liquidity, and farm household labor allocation: the case of rural South Africa

Asset endowments and market imperfections shape households’ labor allocation decisions and lead to different production regimes within rural farm households in South Africa. This article uses a farm household model to explain the presence of three main household groups determined on the basis of the labor regime adopted: small peasants (working both on and off farm), self‐cultivators (autarkic in labor) and hiring‐in households. A partial generalized ordered logit is used to test the main predictions of the model and a Brant test on threshold constancy is performed to identify the household‐specific factors affecting labor market participation. The results show that liquidity constraints and market imperfections matter in the choice of the labor strategy adopted. Liquidity‐constrained households are more likely to sell labor off farm while access to information facilitates the hiring in of workers.     

A hedonic approach to estimating the supply of variety attributes of a subsistence crop

The article extends the household hedonic model by estimating a supply function for variety attributes of a subsistence crop in a developing economy. The model is applied to bananas in Uganda, making use of disaggregated data on variety‐specific farm‐gate banana bunch prices and attributes, while accounting for the semisubsistence nature of banana‐producing households. The article is motivated by the need to understand the attribute trade‐offs made by farmers at the farm gate in light of targeted variety improvement efforts and their impact on banana markets. Whether variety improvement will pay off at the market level requires a more detailed examination of the relative worth of banana attributes within the structure of consumer preferences and production technologies related to bananas in Uganda. The results confirm the importance of consumption and production attributes in selling behavior. Quality and bunch size are found to be complements at the farm gate. Banana bunches that capture a premium at the market will be those that provide bundles of desirable consumption and production attributes simultaneously. By revealing important price–attribute relationships, the findings provide guidance for crop improvement efforts and diversification choices, while taking into account implicit market signals for output attributes.     

Incomplete Credit Markets and Commodity Marketing Behaviour

We use a simple theoretical model of seasonal market participation in the presence of liquidity constraints and transaction costs to explain the ‘sell low, buy high’ puzzle in which some households do not take advantage of inter‐temporal price arbitrage through storage and sell output postharvest at prices lower than observed prices for purchases in the subsequent lean season. We test our model with data from western Kenya using maximum likelihood estimation of a multivariate sample selection model of market participation. Access to off‐farm income and credit indeed seem to influence crop sales and purchase behaviours in a manner consistent with the hypothesised patterns.     

The adoption of intensive monocrop horticulture in southern Cameroon

Results from a 1997 survey of 208 households in the humid forest zone of southern Cameroon indicate that African policy makers seeking to intensify agricultural production should focus attention on the horticultural sub‐sector. The survey, which gathered information on horticultural production practices, found that the average expenditure on agro‐chemical inputs by horticultural producers using monocrop production systems was 190US$/ha, which greatly exceeds the FAO reported national average expenditure of 6.50 US$/ha. A logit model of monocrop adoption indicated that the size of land holding per household had a negative effect on adoption, congruent with population‐driven technical change and that increases in unit transportation costs significantly decreased the probability of adoption. These findings suggest that policy makers should target horticultural intensification in areas of higher population density and promote investment in rural roads. The age of the household head had a significant negative and elastic effect on adoption, which in combination with an increase in the cohort of younger farmers in the rural population induced by macro‐economic events contributed to the spread of intensified horticulture. In the study area, roughly two‐thirds of rural households also produce cocoa and the quantity of cocoa produced was positively associated with adoption of intensive horticultural systems suggesting that export crop promotion indirectly facilitated diversification of agriculture. Women's participation in intensive monocrop production was limited and efforts to promote their greater involvement are recommended.     

A latent class approach to investigating demand for genetically modified banana in Uganda

This study explores consumer acceptance and valuation of a genetically modified (GM) staple food crop in a developing country prior to its commercialization. We focus on the hypothetical introduction of a disease‐resistant GM banana variety in Uganda, where bananas are among the most important staple crops. A choice experiment is used to investigate consumer preferences for various attributes related to the banana (such as bunch size, technology, producer benefit, and price) and examine their opinions on GM foodstuff. Choice data come from 421 banana‐consuming households randomly selected from three regions of Uganda. A latent class model is used to investigate the heterogeneity in consumers’ preferences for selected attributes related to the banana and to profile consumers who are more or less likely to accept GM bananas. Our results reveal that there is significant heterogeneity in consumer preferences across our sample. GM bananas are valued the most by poorer households located in the rural areas of the Eastern region. These food‐insecure households would experience the highest benefits (i.e., welfare gains) from the commercial release of GM bananas. In contrast, urban consumers are less accepting of GM bananas, and they would experience significant welfare losses if GM banana is released. According to our welfare estimates, both the total welfare benefits acquired by the gainers and the total welfare losses borne by the losers of this technology are significant and large. These results suggest the need for further investigation of the overall welfare effects of the introduction of GM bananas on the Ugandan society as a whole.     

Modeling Farm Households' Price Responses in the Presence of Transaction Costs and Heterogeneity in Labor Markets

We develop a farm household model to analyze price responses of farm households. This model incorporates various types of transaction costs as well as labor heterogeneity. Nonproportional variable transaction costs or labor heterogeneity imply that production and consumption decisions become nonseparable, even when the household buys or sells labor. An empirical model is estimated using data from Midwest Poland. The results show that nonproportional variable transaction costs and labor heterogeneity significantly influence household behavior. Not all price elasticities, however, change significantly if these are neglected.     

Dynamics of smallholder participation in horticultural export chains: evidence from Ecuador

We study the dynamics of smallholder participation in export value chains focusing on the example of small‐scale broccoli producers in the highlands of Ecuador. Combining cross‐sectional data from a household survey with 11‐year longitudinal data on export market transactions, we explain the hazards of dropping out of a high‐value export chain. We apply a multispell cox duration model that allows us to consider multiple entries and exits from the supply chain. We also provide evidence on the welfare impacts associated with participation. The results suggest that small‐scale farmers’ exit from the export sector is accelerated by high transaction risks experienced in the past. While we find no particular evidence for the exclusion of small‐scale farmers from the export sector, we do find that poorer households and female‐headed households tend to drop out faster, especially as long as the sector is still prospering. Finally, when considering welfare effects, we do not find evidence that participation translates into tangible benefits for broccoli farmers. We discuss some measures that could help improve the long‐term sustainability of smallholder integration in high‐value chains.     

The dynamics of Chinese rural households' participation in labor markets

The work is devoted to the dynamics of labor market participation of Chinese rural households. Based on a theoretical farm household framework the choice between four distinct labor market participation states is empirically analyzed. Using household data over the period 1995–2002 from the province Zhejiang we apply a discrete time hazard approach to analyze households' labor market participation histories. In particular, we investigate the movements between autarky and participation in general and, more specifically, the shifts between part-time and full-time farming. Estimation results suggest significant duration dependence, more precisely, a decreasing risk of moving from one state to another with an increasing time a household occupies one of these states. Further, the likelihoods of starting any participation in labor markets and to start part-time farming are considerably higher than to end participation or to return to full-time farming. In addition, we find that labor market participation decisions are significantly related to several household and farm characteristics.

The impact of the 2005–2010 rice price increase on consumption in rural Bangladesh

This article studies the impact of the rice price increase between 2005 and 2010 on consumption in rural Bangladesh. Using the Household Income and Expenditure Survey (HIES) data, we compare net rice buyers and sellers to self‐sufficient households. To identify the effect of rice price changes on household consumption of rice, nonrice food and nonfood items, we employ a difference‐in‐differences (DiD) technique. Our findings indicate that the surge in domestic rice prices between 2005 and 2010 reduced the nonrice food consumption of net rice buyer households by 7%, compared to the households who are self‐sufficient in rice production. However, it did neither affect their rice nor their nonfood consumption. In contrast, while we find no significant effect of rice price increases on the rice consumption of net rice sellers, we observe a 9% increase in their nonrice food consumption. In such situation, a subsidy on low‐quality rice may be effective in fulfilling the nutritional requirement of low‐income households.     

Off‐farm labor market decisions and agricultural shocks among rural households in Kenya

Using household level data from rural Kenya, this article explores whether and how farm households respond to unfavorable agricultural production environments, including any ex post adjustments in off‐farm labor supply in response to unexpected weather shocks. While controlling for a wide range of educational, demographic, and other locational factors, we examine how long‐term weather conditions and specific rainfall shocks influence a household's decision to engage in, and their earnings from, the off‐farm labor market. We find that rural households engage in off‐farm work as a long‐term strategy to deal with the effects of anticipated weather conditions on their farming operations. The analysis does not reveal major short‐term adjustments in off‐farm engagement as a result of specific, unexpected rainfall shocks; these households do however rely on remittance income and petty agricultural wage labor under these circumstances. Holding other factors constant, and conditional on participation, households in areas with a more productive local agriculture tend to earn more from off‐farm work especially in the informal/business sector than their counterparts in regions with a less productive agriculture. As expected, a vibrant local economy in the form of public investment increases the probability of off‐farm participation.     

Smallholder participation in vegetable exports and age‐disaggregated labor allocation in Northern Tanzania

Modern agricultural supply chains have been playing an increasingly important role in developing countries and have had significant effects on rural labor markets. This article analyses the effects of smallholder farmer participation in export vegetable supply chains in Northern Tanzania on both household hired labor demand and off‐farm labor supply, using an age‐disaggregated approach. In our sample, neither separability nor exogeneity of smallholder farmer participation in export supply chains can be rejected. Hence, we apply lognormal double‐hurdle models and find that participation in export supply chains positively affects households’ decision to hire labor from all age groups. We also find that it increases the unconditional overall level of hired labor demand, while the age‐disaggregated analysis shows that these effects mostly benefit rural youth. However, our sample does not allow us to establish statistically significant evidence of an effect on household off‐farm labor supply although the point estimates point to nonnegligible positive effect sizes.     

The estimation of long term impacts of China's key priority forestry programs on rural household incomes

We use a large unique household panel dataset spanning 16 years to estimate the impacts of three Key Priority Forestry Programs (the KPFPs) in China on household incomes. The programs are the most significant of China's forest policies namely the Sloping Land Conversion Program (the SLCP), the Natural Forest Protection Program (the NFPP), and the Desertification Combating Program around Beijing and Tianjin (the DCBT). A fixed effect model with clustered standard errors is used to identify programs’ impacts based on variation in participation across households and time. In addition to estimating the total impacts of these programs, individually and in combination, we disaggregate the effects by income source, stage of policy implementation, and duration of participation. Overall, the impacts of the KPFPs on rural households’ income vary with time of enrollment and policy stage. We observe that the KPFPs in their initial stages of implementation, and for the early years of household participation, had negative, or at best neutral impacts on household incomes, in particular incomes from land. However, the later stages of the SLCP and the DCBT have tended to raise land-based incomes, and the NFPP has ceased to have a negative effect. This is likely to be in part the result of adjustments made by rural households over time in response to changes in the programs, as well as in market and environmental conditions.     

A trait-based model of the potential demand for a genetically engineered food crop in a developing economy

We predict the potential demand of smallholder farmers for genetically transformed varieties of a food crop, the cooking banana of the East African highlands. Farmer demand for planting material is derived in an agricultural household model that accounts for variety traits and missing markets. The demand for candidate host varieties is predicted using a Zero‐Inflated Poisson (ZIP) regression system. The fitted model is used to illustrate the sensitivity of farmer demand for improved planting material to (a) investments in research and development, represented by the effectiveness of gene insertion and expression, and (b) other public investments in education, extension, and market infrastructure that support diffusion. By comparing the characteristics of agricultural households we demonstrate that the choice of host variety can have social consequences, favoring one rural population compared with another. Clients for transgenic banana planting material are likely to be poorer, subsistence‐oriented farmers in areas greatly affected by biotic constraints. A model of this type might be useful in assessing the investments needed to support the systematic dissemination of improved planting material. The approach can be generalized to other crop biotechnologies for smallholder farming systems, particularly in developing economies.     

Effect of off‐farm income on smallholder commercialization: panel evidence from rural households in Ethiopia

This article investigates how off‐farm income affects crop output market participation decisions and marketed surplus of smallholder farmers in Ethiopia. A double‐hurdle model is estimated using three waves of panel data from the Ethiopian Rural Household Survey. Unobserved heterogeneity is controlled for using a correlated random effect procedure and potential endogeneity of explanatory variables using a control function approach. The results show that off‐farm income has no significant influence on household crop output market participation. However, conditional on market participation, additional off‐farm earnings negatively affect the marketed surplus. This indicates that farmers use off‐farm earnings for consumption rather than for investment in agricultural production. Policy measures that promote rural investment may help increase returns to labor for land‐poor households participating in off‐farm work in the process of agricultural commercialization.     

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.     

Drivers of transaction costs affecting participation in the rental market for cropland in Vietnam

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.
