Nonfarm employment,agricultural intensification,and productivity change: empirical findings from Uganda

This article uses panel data from the Living Standards Measurement Study‐Integrated Surveys on Agriculture for Uganda to assess the farm‐level effects of nonfarm employment on agricultural intensification and productivity change. A sample selection model is used to account for both unobserved heterogeneity and potential simultaneity between agricultural production and nonfarm income. Results show that nonfarm employment can have differential impacts on farm technology intensity and productivity. Nonfarm income is found to have a positive impact on farm hired labor and improved seed intensity; a negative effect on on‐farm family labor use; and no significant impact on fertilizer, soil water management, and joint use of farm technologies. The econometric evidence also indicates that agricultural productivity declines as nonfarm income increases. Taken together, our findings reveal important trade‐offs between nonfarm employment and income and farm productivity growth under smallholder agriculture. The results indicated that targeted policies are required to reduce these potential trade‐offs between nonfarm employment and agricultural intensification and productivity change.     

The increasing importance of nonfarm income and the changing use of labor and capital in rice farming: the case of Central Luzon, 1979–2003

There have been sharp increases in nonfarm income among farm households in Central Luzon for the last few decades. This study attempts to identify the effects of the increasing nonfarm income on the use of tractors and threshers and on the employment of hired labor as a substitute for family labor. We found that while the increased nonfarm income positively affects the ownership of tractors, it has no significant impact on the use of agricultural machines due presumably to the development of efficient machine rental markets. We also found that the increased nonfarm income leads to the increased use of hired labor, thereby releasing family labor to nonfarm jobs.     

New evidence regarding the effects of contract farming on agricultural labor use

Contractual agreements between smallholder farmers and agribusiness companies have gained in importance in many developing countries. While productivity and income effects of contracting in the small farm sector were analyzed in many previous studies, labor market and employment effects are not yet well understood. This is an important research gap, especially against the background of continued population growth and structural transformation. Here, we investigate the effects of two types of contractual agreements between large international processing companies and smallholder farmers on agricultural labor use, household labor allocation, and hired labor demand in Ghana's palm oil sector. We use cross‐sectional survey data and a willingness‐to‐pay approach to control for unobserved heterogeneity between farmers with and without contracts. We find that agricultural labor intensity is substantially reduced through the contracts, because contracting in Ghana is associated with the adoption of labor‐saving procedures and technologies. Simple marketing contracts lead to reallocation of the saved household labor to off‐farm employment, whereas resource‐providing contracts lead to a stronger reallocation of labor within the farming enterprise. Household labor is more affected by labor savings than hired labor.     

Multiple job holdings among dairy farm families in New York and Ontario

Previous empirical studies of multiple job holding have tended to focus on the characteristics of those obtaining off-farm employment and the factors affecting the hours supplied to those obtaining off-farm activities. None of these studies have explicitly addressed the reasons behind the decision to seek off-farm employment. Neither have they been able to examine in-depth the important issue of how this major component of the farm sector responds to alternative policies, since most studies have used cross-sectional data for a given region. A comparison between countries would permit the analysis of how multiple job holding responds to differing government policies. The purpose of this paper is to examine the reasons for and factors affecting multiple job holdings of dairy farm families in neighboring regions of two counties, United States and Canada. The bordering regions of New York and Ontario have similar geographic conditions but significantly different farm support and social service policies. The results indicate the importance of farm income on why people work off the farm and provide evidence of multiple job holding as a flexible mechanism for coping with changes in the economic environment facing the household. For operators, the driving characteristics influencing off-farm labor participation is the farm's financial position. The supply-managed milk marketing system ensures higher and more stable returns for Ontario dairy farm labor. In contrast, it is family demographics, educational level and social support policy that appears to largely influence spousal off-farm employment decisions. Free medical care in Ontario lowers the reservation wage for household members. The effect of these farm and social support policies on the relative returns to labor in agriculture and non-farm employment explains the lower participation rate and hours supplied in off-farm work by both operators, and hours supplied in off-farm work by both operators and spouses in Ontario dairy farm household.     

The Theory of the Farm Household: An Application to Saskatchewan

A theoretical model is presented which integrates the consumption and production components of the rural household. A theoretically determined system of expenditure equations, derived factor demand equations and an off-farm labor supply equation are estimated using primary data for Saskatchewan farm households. From the empirical results we conclude that if the wage rate can be observed or estimated, the farm household's behavior can be explained empirically in a manner consistent with received theory. Summary and Conclusions A theoretical model integrating the consumption and production sides of the farm household or enterprise is estimated empirically using primary data for Saskatchewan farm households. The farm household was assumed to maximize its utility function subject to farm production and cash flow constraints. The empirical results indicate that the theoretical model can be estimated successfully even when data are sparse. While the coefficients for the expenditure, derived demand, and off-farm labor supply equations are consistent with coefficients from similar equations estimated separately by others, the theoretically more precise integrated approach specifies the simultaneous effect of the variables across equations. From the empirical results and the theoretical considerations it is obvious that the wage rate is a key explanatory variable in the model. The wage rate links the three components of the model–final expenditures, the derived input demands and off-farm labor hours. The wage rate is one determinant of the allocation of the operator's time (although other factors such as the nature of the operation and opportunities to work off-farm dominated in this study), and both the wage rate and the allocation of the time determine the eventual income available to the rural household. In essence, then, the problem of explaining farm household behavior when the household's business enterprise function cannot be separated from its consumption activity is similar to that of traditional models based on the theory of the firm and models of consumer behavior. The only difference is that the wage rate is observable in the traditional models but needs to be estimated as a shadow price in models which seek to explain rural household behavior. As a result, research in this area must start with an explanation of the allocation of (at least) the operator's labor and a measure of the shadow wage rate. If the entire household's allocation of time between on-farm and off-farm labor and leisure is determined, it is possible to treat its consumption and production activities separately. Further research is required to extend the model to explain household labor supply to both the farm and off-farm labor markets.     

Hired labor use decisions in cassava-producing households of sub-Saharan Africa

Sub‐Saharan Africa is the only developing region of the world where agricultural output has been trailing population growth for most of the last three decades. Farming systems in the region are inherently risky because they are fundamentally dependent on the vagaries of weather. In addition, it is a region of crises; poverty, civil strife, and HIV/AIDS. Attention must therefore be focused on improving the production of crops that could thrive under these circumstances. Because of its tolerance of extreme drought and low input use conditions, cassava is perhaps the best candidate in this regard. And cassava is a basic food staple and a major source of farm income for the people of the region. The use of hired labor is important for its production growth because cassava root yield responds positively to the application of hired labor. This article, based on farm‐level information collected from six major cassava‐producing countries of Africa, within the framework of the Collaborative Study of Cassava in Africa, identifies strategic variables affecting the hired labor use decisions of producing households. The characteristics of the household head (age and number of years of formal education), the size of the household farm, good market access, and population pressure are found to motivate households to apply hired labor in cassava production. These observations underscore the need for investing in people—education—and in infrastructure—market access—as possible tools for improving food production in the region. The positive effect of farm size also suggests that some kind of land reform, which would put more farmland at the disposal of farm households, could be favorable to improving cassava production.     

How poor are women in rural India?

The assessment of poor women in India as dependent and exploited regardless of poverty focused strategies is reflected in this review of relevant literature. The scholarly approaches to the problems of poor women involve redirection and expansion of resources to women (increase bank credit) through policy and institutional changes, and involve improving women's welfare through changes in class and gender hierarchies; both pertain to restructuring power groups. A little ascribed to belief is that the organization of women's numbers will empower women; the constraints are stated. There is also some argument over whether to design women-specific programs or integrate women into existing programs; some examples are given of successes and difficulties. The regionalization of poverty in eastern and central India is discussed. The growth of the poor has been among the landless, wage-dependent households. 9.6% of households (7.5 million) are headed by women. Women work fewer hours and at lower wage scales and have fewer employment opportunities. Lower earnings are coupled with differentials in demand for female and male labor in agriculture and a crowded labor market. There is a concentration of women in less visible, nonmonetary subsistence production and domestic work. Women are undercounted in employment studies. Women predominate in agricultural activity. Women's status is influenced by economic status, caste, and ethnic background. Domestic work increases status for women and households. The poorer households have greater labor force participation, particularly as wage laborers rather than unpaid family workers. Regional factors affecting rural household strategies are factors affecting the economy (topography, rainfall, climate) and the degree of development, plus sociocultural variables (kinship and religious beliefs which affect the social domain of women), and the degree of dependence on hired vs. family labor. There are sharp contrasts in the value and survival of women regionally. Female labor force participation is low in all regions; the nature and distribution of agricultural laborers is discussed followed by examples from 3 different regions (east, south, and north). The gender inequalities in access to basic needs are reviewed for sex ratio, mortality, and nutrition, and education. The preference is for gender-based policies targeting women.     

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.     

Modern rice technology and regional wage differentials in the Philippines

Fear has been widely expressed that the modern rice varieties have created large disparities in regional income distribution, as the productivity gap between favorable and unfavorable rice-production environments widened due to differential technology adoption throughout South and Southeast Asia over the last two decades. Technology affects the income of farm population directly through its effects on productivity and factor use, and indirectly through its effect on factor prices. In particular, the ultimate distributional impact of modern varieties will critically depend on the interregional labor-market adjustments through migration in response to regional wage differentials created by the differential technology adoption, since labor is the main resource of the majority of the rural population. We studied favorable and unfavorable rice-growing villages in the Philippines, and found that adoption of modern varieties during the 1970s was positively related to population growth rate. Contrary to popular belief, no association was observed between wage rates and adoption of modern varieties as of 1986. These findings support the hypothesis that the differential adoption of modern rice varieties induced interregional labor migration toward equalization of wage income across different production environments.     

Well‐off small‐scale tobacco growers and farm workers in the Mexican agrarian reform (1972–1990)

In this article, I study small‐scale growers of blonde tobacco varieties from the state of Nayarit in Mexico who had contract farming arrangements with the state‐owned company Tabamex (1972–1990). I refer to them as “well‐off small‐scale tobacco growers” given that in the 1960s, 1970s, and the 1980s, they became one of the subaltern social groups that benefited the most from the Mexican Agrarian Reform. I want to set this research apart from the ones carried out on tobacco growers in Nayarit, which have almost exclusively understood this group as agricultural producers and have perceived as secondary, and even as anecdotal, the impact of the high levels of wage labour hired in the region. I argue that in order to have a better understanding of the social relations at play, it is important to take into account that Nayarit tobacco growers have also been employers of farm workers. Hence in my analysis, I have also included the seasonal farm workers hired by these small‐scale tobacco growers because of their importance in the labour force. More specifically, I have looked into the vulnerability and invisibility of these workers both within this branch of agricultural activity and state institutions.     

Distortions to World Trade: Impacts on Agricultural Markets and Farm Incomes

The latest versions of the Global Trade Analysis Project database and the Linkage model of the global economy (projected to 2015) are used to estimate the impact of removing all merchandise trade distortions (including agricultural subsidies). Results suggest that a move to free merchandise trade would increase farm employment, the real value of agricultural output and exports, real returns to farm land and unskilled labor, and real net farm incomes in developing countries. This would occur despite the decline in international terms of trade for some developing countries that are net food importers or are enjoying preferential access to agricultural markets of high-income countries.     

Intertemporal analysis of employment decisions on agricultural holdings in Slovenia

The article attempts to quantify determinants influencing the dynamics of employment decisions on agricultural holdings in Slovenia and to test specific aspects of labor reallocation during the transition period by the application of an agricultural household model. Through the use of a 1991–2000 longitudinal data set for 22,055 farm households, quantitative analysis of intertemporal employment decisions by farm holders is carried out using probit techniques. The determinants tested relate to the personal characteristics of farm holders (gender, age, education level, and potential off‐farm income), household characteristics (size, structure), characteristics of the agricultural holding (economic size, labor intensity), and local labor market conditions. The model results generally confirm existing empirical evidence on asymmetrical and irreversible participation of holders on the labor market. Despite intensive restructuring of agriculture and profound changes in the nonfarm labor market in the analyzed period, labor supply of farm holders remains rigid. The mobility of labor supply is lower than expected, which can be attributed to the importance of structural problems constraining intersectoral mobility. Low labor mobility reduces the efficiency of labor allocation on agricultural holdings in Slovenia. Elements of this problem emerge on both supply (e.g., low level of educational and professional attainment of reference persons) and demand sides of the labor market (e.g., unfavorable local labor market conditions). A marked tendency toward maintaining the same employment status is more distinct in the case of holders employed on‐farm only.     

Efficiency Wages, Deferred Payments, and Direct Incentives in Agriculture

Empirical evidence from agricultural labor markets is consistent with efficiency–wage theory and inconsistent with several alternative explanations. According to this theory, the higher wage or deferred payment (benefits) that direct–hire growers pay relative to that of farm labor contractors is an efficiency wage. Growers use this extra compensation to lower their monitoring expenses and reduce shirking by workers.     

SIMULATED MARKETS,FARM STRUCTURE,AND AGRICULTURAL POLICIES*

In this investigation estimated relationships of resource markets for United States agriculture are used in a simulation model to study resource demand and farm income under three conditions: (a) those actually prevailing, including the historic mix of agricultural policies, (b) with technical change in agriculture only half the rate realized, and (c) with a free market. The results indicate that compared with “actual” conditions the environment of slow technical change would have modest effects in slowing the demand for farm machinery and the migration of labor from agriculture. It also would result in greater net farm income in the 1960's. A free market would be accompanied by increased investment in farm machinery and a greater exodus of family and hired labor from agriculture. It also would result in a smaller farm building investment and a considerable reduction of farm income. Since economic conditions are so similar in both countries, the implications of these findings are related to Canadian agriculture on the assumption the same model would show the same outcomes for Canada. Dans cette étude, des rapports estimés des marchés des ressources pour ?agriculture des Etats-Uns sont employés dans un modéle de simulation afin ?étudier la demande des ressources et le revenu agricol net sous trois conditions: (a) celle qui régne réellement, incluant le mélange historique de politiques agricoles; (b) celle qui ne montre le changement technique de ?agriculture qti à la moitié du train realise; et (c) celle qui profite ?un marché libre. Les résultats indiquent que ?enrironnement du changement technique modéré, quand il est compareé avec les conditions réelles, produirait des effets modestes en diminuant la demande pour des machines agricoles et en ralentissant ?exode de la main-?oeuvre de ?agriculture. En outre, cet environment aurait pour résultat un revenu agricole net plus fort dans les années de 1060 à 1970. Vne marché libre serait accompangne de placements augmentés dans les machines agricoles et ?un plus grand exode de la main ?oeuvre familiale et salariée de ?agriculture. Aussi, ceci aboutirait à un investissement moindre dans la construction rurale et à une réduction considérable du revenu agricole. Puisque les conditions économiques des deux pays sont si ressemblantes, les implications de ces conclusions sont rattachées à?agriculture cana-dienne en supposant que le même modéle montrerait les mêmes résultats pour le Canada.     

The Influence of Labor Price Change on Agricultural Machinery Usage in Chinese Agriculture

The substitution between rural labor and machinery has been a key determinant of farm production, structure, and efficiency in most developed countries and is expected to play a key role in shaping the future of Chinese agriculture. Using disaggregated farm‐level data from Hebei and Shandong provinces of China, we calculated the Allen and Morishima elasticities of substitution between labor and machinery. These elasticities were based on seemingly unrelated regressions and three‐stage least squares estimates of the translog cost function and input cost share functions. In contrast to previous studies, we dissaggregate machinery inputs into three categories: large, medium, and small. In addition, the issue of endogeneity in output quantity and input prices is also addressed. The results show strong evidence of substitution between labor and the three categories of machinery inputs. The findings also support substitution among the three categories of machinery themselves.     

FARMERS‘ WIVES - THEIR CONTRIBUTION TO THE FARM BUSINESS

The contribution which farmers' wives make to the farm business is typically overlooked and under-valued, yet the farm could not function without it. The paper describes the nature of the work done by wives on farms in the UK and Ireland as revealed by two recent postal surveys. Using data from the Farm Business Survey for England and Wales, it attempts to quantify some aspects of the work. It is suggested that farm wives may contribute 5 per cent of the manual hours worked by the regular labour force and 9–10 per cent of the total regular labour input on main holdings. Further, as hired and family labour is shed and farmers seek additional employment, the wife's labour contribution is likely to become more significant. Continued neglect of women's involvement may jeopardise the future of the family farm. The paper suggests how data collection procedures might be improved to give a more realistic picture of the wife's contribution.     

Farm work, off-farm work, and hired farm labour: estimating a discrete-choice model of French farm couples' labour decisions

We model jointly several types of discrete-choice labour decisionsof farm couples: farm work, off-farm work and hired farm labour.Rather than estimating a set of reduced-form participation equationsthat is subject to an internal inconsistency problem, we estimatea 16-choice multinomial model. We find that farm labour of operatorsand of spouses are substitutes. Hired farm labour increaseswith the farmer's qualifications, perhaps substituting for thecouple's labour inputs. Other adults in the household substitutefor the farm labour input of the farm couple and hired workers.We find that the organisation of work by French farm householdshas changed over time, in the direction of a more equal sharingof tasks and responsibilities between members of the farm family.     

Off-farm Labour Supply with Productivity Increases,Peak Period Production and Farm Structure Impacts

The study of of-farm employment of farm family members in the context of a neoclassical time allocation model of labor supply is used to attempt to explain the amount and type of off-farm employment currently prevalent on the Canadian Prairies. The effect of labor saving technical change together with a production process characterized by periods of peak activity affect the priority that may be assigned to off-farm work These factors require explicit consideration in the theoretical framework for the study of off-farm employment. The refinements occasioned by expanding the paradigm in this manner have implications for the role of rural development policy in the support of the agricultural sector     

中国农村留守妇女的劳动供给模式及其家庭福利效应

男出女守的家庭分工改变了中国留守妇女的劳动供给模式,留守妇女保留工资较低、劳动参与率较高以及工资性工作时间较长,表明其劳动供给更接近合作博弈模型所描述的女性劳动力供给行为。留守妇女的家庭分工和劳动供给模式有利于家庭短期经济状况的改善,但同时也使得女性的家庭事务、工资性工作和农业劳动负担加重,不利于家庭的长期利益和不同家庭成员的长期福利。留守妇女的多重角色冲突导致原有的家庭利益平衡机制和稳定状态受到冲击,并且由于目前中国农村仍然缺乏有效的市场化和社会化途径将家庭短期经济收入转化为长期利益,因而短期内无法有效缓解家庭冲突和矛盾。     

Wage and employment effects of Malawi's fertilizer subsidy program

This article uses three waves of nationally representative household‐level panel data from Malawi to estimate how a large‐scale fertilizer subsidy program impacts the agricultural labor market, known as ganyu in that country. I find that when looking across the entire population of smallholders, receiving an additional 100 kg of subsidized fertilizer causes the average household to supply about three fewer days of ganyu. The fertilizer subsidy program also has a small positive effect on the probability that a household demands agricultural labor, with the results approaching statistical significance. In addition, a 10 kg increase in the average amount of subsidized fertilizer acquired per household in a community boosts the median agricultural wage rate by 1.4% in that community. The increase in wage rates translates to a US $1.40 per year increase in average household income in the years after Malawi's subsidy program was scaled up, and a US $1.86 per year increase in average household income for those who sold their labor before the subsidy program was scaled up. This finding suggests that households who sell their labor off farm may experience some small spillover benefit from the program in the form of higher agricultural wage rates.
