Farm household economics: Some policy implications for emergent farmers in Southern Africa

Farm household economics recognises the fact that production and consumption decisions are made jointly by small farm (ie surplus‐producing) households. This phenomenon is of particular importance in areas where small farm households predominate.

Most empirical applications of farm household economics have been directed at measuring the effects of price changes on consumption and have relied on the ‘separable’ approach in deriving estimates. This approach assumes that production decisions always precede consumption decisions with farm households treated as profit maximizers in production and utility maximizers in consumption. Results have clearly demonstrated consumption responses smaller than estimates based on consumer theory alone.

Although many researchers regard mathematical programming as a potentially suitable tool for simulating smallholder behaviour, proponents of new household economics would be reluctant to accept any model that does not (a) maximize utility (rather than profit) and (b) capture the ‘profit effect’ which variations in product prices have on the farm household's full‐income constraint. Attempts to include these basic postulates of farm household economics in programming models are in progress.     

Farm Household Responses to Government Policies: Evidence from West Java

Few micro level analyses have been undertaken in Indonesia of rural households' responses to government policies, and of household characteristics and endowments. Most studies of rural household behaviour in Indonesia have analysed the consumption, production and labour supply aspects separately, ignoring the complex interrelations among farm production, farm profit, household consumption and family labour supply. In this study, the complex nature of rural household production and consumption decisions is analysed by applying a farm household model to cross-sectional data from 241 households in six villages of West Java. The model incorporates multiple crops, different wage levels for males and females, and non-agricultural employment.     

Alternative Poverty Lines for Malaysia

Because of the shortcomings of the Malaysian official poverty line, this paper offers several alternative regional poverty line estimations with varying underlying assumptions. Using the Household Expenditure Survey 2004/2005, poverty lines are estimated based on the consumption patterns of 10th and 20th percentile household per capita expenditure. The regional poverty lines from these reference groups produced robust poverty measurement rankings across regions in the country. We suggest that the poverty lines from both reference groups be used as lower and upper poverty lines for the country.     

A model of real and financial household behaviour

Summary This paper shows that the traditional specification of the consumption function in Dutch macroeconometric models is unsatisfactory. In the traditional approach the fact that the consumption decision is taken simultaneously with financial decisions has been ignored. If both the consumption function and the asset demand equations are modelled simultaneously, then in the Dutch case financial stocks have influence on private consumption. Also it has been shown that the income concept is important in describing household behaviour. In a current income model short-term financial considerations are important in the consumption decision. In a permanent income model long-term financial considerations influence private consumption.The author would like to thank Professor Th. van de Klundert, Professor S.K. Kuipers, Mr. G.H. Kuper and Dr. N.S. Kroonenberg for their comments on an earlier version of this paper.     

Urban working‐class food consumption and nutrition in Britain in 1904

This article re‐examines the food consumption of working‐class households in 1904 and compares the nutritional content of these diets with modern measures of adequacy. We find a fairly steep gradient of nutritional attainment relative to economic class, with high levels of vitamin and mineral deficiency among the very poorest working households. However, we conclude that the average unskilled‐headed working household was better fed and nourished than previously thought. When proper allowance is made for the likely consumption of alcohol, household energy intakes were significantly higher still. We investigate the likely impact of contemporary cultural food distribution norms and conclude on the basis of the very limited evidence available that women may have received, on average, about 80 per cent of a man's share of the available food. We adjust energy requirements for likely higher physical activity rates and smaller stature and find that except among the poorest households, early twentieth‐century diets were sufficient to provide energy for reasonably physically demanding work. These results are consistent with recent attempts to relate the available anthropometric evidence to long‐run trends in food consumption. We also find that the lower tail of the household nutrition distribution drops away very rapidly, so that few households are estimated to have suffered severe food shortages.     

E-commerce and Consumption Inequality in China

Consumption inequality may impede economic development and hinder the achievement of common prosperity. Using three waves of the China Family Panel Studies from 2014 to 2018, this paper investigated the impact of e-commerce on consumption inequality, as measured by the Kakwani index. The results indicate that e-commerce can reduce household consumption inequality. A mechanism analysis shows that e-commerce can narrow household income inequality, increase the purchasing power of low-income households, and promote the consumption of households with limited access to offline markets, thereby reducing the consumption gap. A heterogeneity analysis suggests that the positive role of e-commerce in reducing consumption inequality can be more significant among vulnerable households, such as households with elderly members and less-educated households. E-commerce can have varying impacts on consumption inequality across different subcategories of household expenditure, with the greatest impact seen in entertainment and education expenditure. These findings provide new evidence for the role of e-commerce in reducing consumption inequality in the digital economy, and the implications of this are discussed.     

Chinese household saving and dependent children: Theory and evidence

This paper examines the impact of family size on household saving. We first study a theoretical life-cycle model that includes finite lifetimes and saving for retirement and in which parents care about the consumption by their dependent children. The model implies a negative relationship between the number of dependent children in the family and the household saving rate. Then, we test the model's implications using new survey data on household finances in China. We use the differential enforcement of the one-child policy across counties to address the possible endogeneity between household saving and fertility decisions in a two-stage least squares Tobit regression. We find that Chinese families with fewer dependent children have significantly higher saving rates. The data yields several additional insights on household saving patterns. Households with college-age children have lower saving rates, and households residing in urban areas have higher saving rates and a lower ratio of education expenditures to income. However, having an additional child reduces saving rates more for households in urban areas than in rural areas. Our regressions also indicate that saving rates vary with age and tend to be higher for households with more workers, higher education, better health, and more assets.     

Role of Education in Cigarette Smoking: An Analysis of Malaysian Household Survey Data*

Heckman's sample selection model is used to examine the role of education on household purchase decisions and expenditures of tobacco products in Malaysia. Results of the marginal effects of education, segmented by ethnic and gender groups, suggest that education decreases the probability, conditional levels and unconditional levels of tobacco expenditures amongst Malaysian households. Specifically, an additional year of education of the household head, irrespective of ethnic or gender considerations, decreases smoking probability by 1.5 percent. However, the negative effect of education seems to be higher for Chinese (US$1.07) than Malay (US$0.26) households in terms of conditional expenditures. Furthermore, education significantly decreases conditional tobacco expenditures within male‐headed households.     

Household schooling and child labor decisions in rural Bangladesh

Using empirical methods, this paper examines household schooling and child labor decisions in rural Bangladesh. The results suggest the following: poverty and low parental education are associated with lower schooling and greater child labor; asset-owning households are more likely to have children combine child labor with schooling; households choose the same activity for all children within the household, regardless of gender; there is a weak association between direct costs and household decisions; finally, higher child wages encourage households to practice child labor.     

The role of off-farm employment in the rural energy consumption transition — A village-level analysis in Jiangxi Province, China

Energy consumption in rural areas in China is characterized by high consumption of fuelwood, straw and other biomass. Off-farm employment can play an important role in the transition towards more sustainable sources of energy by increasing rural household incomes and reducing the amount of labor available for biomass collection. The purpose of this paper is to examine the impact of off-farm employment on rural household energy consumption choices, and to disentangle the various causal relationships that play a role in this respect. To this end, a hybrid farm household/village computable general equilibrium (CGE) model is used that has been calibrated for a remote village in Northeast Jiangxi Province where fuelwood is the main source of energy. The model takes into account nonseparability of farm household production and consumption decisions as well as linkages within the village between households involved in off-farm employment and households with no members working off-farm. Contrary to previous research for a richer region in rural China, we find that fuelwood is not an inferior good. The positive impact of more food consumption on fuelwood collection more than compensates the higher leisure demand associated with higher incomes. Shifts in production activities and in prices on village factor markets caused by increased labour scarcity (the lost-labour effect of off-farm employment), on the other hand, cause a reduction in fuelwood collection and consumption. This lost-labour effect is much stronger for migration than for local off-farm employment, because the latter can more easily be combined with on-farm work and fuelwood collection. For local off-farm employment the income effect dominates the lost-labour effect, resulting in a positive overall impact of higher off-farm participation on fuelwood consumption. For migration, on the other hand, the income effect and the lost-labour effect are almost equal in size. Hence, the amount of fuelwood collected and consumed does not change much when households participate in migration. The final conclusion is therefore that increased off-farm employment opportunities do not promote the transition of rural energy use in the poorer regions of rural China.     

Parental Education and Child Health: Evidence from China*

This paper examines the effect of parental, household and community character‐istics on the health of children in China. We find that birth order, death of elder siblings, use of prenatal care and alcohol consumption by the mother when pregnant have statistically significant effects on the health of children. Although parental education does not have a significant direct effect on child health, it does affect mothers’ behavior during pregnancy and inflfluences the use of health inputs, indirectly impacting the health of children. The research findings have important implications for both family planning programs and broader social policies in China.     

Decisions by Chinese households regarding renting in arable land—The impact of tenure security perceptions and trust

Policies aimed at strengthening tenure security through the elimination of land reallocations and provision of land certificates have been implemented with different degrees of success in rural China. In this study, we examine the impact of tenure security perceptions and trust on household decisions to rent in land in a region where tenure security is high and in a region where households face much lower land tenure security. Our regression results suggest that when land tenure is less secure, household perceptions of tenure security positively affect decisions to rent in additional land and the size of the rented land, whereas trust is important for the choice between oral and written contracts. When land tenure is relatively secure, household tenure security perceptions are less relevant, and trust becomes more important for land rental decisions. However, tenure security perceptions do seem to play a role in the choice between oral and written contracts in such high tenure security environments.     

社会资本、农地流转与农户消费扩张

中国农户消费转型升级引发各方关注,但鲜有从社会资本的视角探讨农地流转对农户消费的影响及其微观作用机理。文章在理论层面分析了农地流转通过影响农户生计资本变动和生计策略调整对农户消费的传导机制,并基于中国家庭追踪调查（CFPS）三期面板数据,定量评估了农地流转对农户消费影响的社会资本效应。结果表明：（1）我国农户消费基尼系数总体呈缩窄趋势,但农地转出农户相比农地转入农户具有更高的人均消费支出及消费不均等程度;（2）农地流转能够影响农户关键自然资本改变和生计策略调整,从而显著提高农户消费水平,且参与农地流转农户相比未参与农地流转农户具有更高的消费动机;（3）社会资本在农户农地转入和转出过程中对农户消费存在微观中介效应,即社会资本越高的农户参与农地流转的概率越大,且能够通过提高农地转出户非农就业机会和扩大其多元化收入来源,间接提升农户消费水平。在精准扶贫和乡村振兴战略协同背景下,应积极有序推进农地适度规模经营,促进农地转出户非农就业,并强化农户社会资本建设,提高农户多元化收入,从而全面助推农村消费转型升级。     

Employment,Wages, and Alcohol Consumption in Russia

This article investigates the association between alcohol consumption and labor market outcomes in Russia, using data from the Russian Longitudinal Monitoring Survey (RLMS). It estimates cross-sectional and fixed effects models of the impacts of alcohol consumption on employment and wages for males and females using three different measures of drinking. The cross-sectional findings indicate that alcohol consumption has an inverse U-shaped impact on employment and wages for females. The impact on males appears to be positive but the inverse-U shape is less pronounced. Once the unobserved individual heterogeneity is accounted for using fixed effects, alcohol consumption is found to have no significant effect on employment for either males or females. The fixed effect wage models indicate that alcohol consumption has a small, positive, but linear impact on the wage rate for both males and females. Models including fixed effects generate estimates that are smaller in magnitude compared with those of cross-sectional models. The findings are robust to several diagnostic checks.     

Home value misestimation and household behavior: Evidence from China

Households often make errors when self-assessing their housing wealth. By using the Chinese Households Finance Survey, we show that Chinese urban households systematically overestimate their home value. This bias is significantly related to household consumption: a one standard deviation increase in the extent of estimation bias is associated with a 10% increase in household consumption. Our main results are robust against a variety of robustness checks, e.g., taking into account the expectations of future home price, using the interviewee's estimation as the instrumental variable for the household self-estimation, implementing the hedonic model on an external data source to assess real homevalue, etc.. Further, we show that overestimated households are more likely to take risk in financial market, and have a larger amount of immediate and conspicuous consumption. These findings have policy implications for the recent debate about property tax, indicating the unintended consequences of property tax through providing more precise information about home value.     

Do International Sanctions Reduce Household and Government Consumption in Developing Countries?

This paper uses a panel of 30 developing countries over the 1996-2015 period to study the effect that international sanctions have on household and government consumption in target countries. I use a broad set of sanctions covering different aspects of sanctions. The panel model estimates show that sanctions have heterogeneous effect on household and government consumption. Household consumption responds significantly negative to noneconomic sanctions. Government consumption, in contrast, is negatively associated with intensity of sanctions, economic sanctions, plurilaterial sanctions, EU sanctions and U.S. sanctions. Disaggregating government consumption reveals that the intensity of sanctions increases government expenditure on subsidies and transfers, while government expenditure on goods and services is not correlated with sanctions. With regard to health outcomes, there is no clear evidence that sanctions are significantly associated with either life expectancy or infant mortality in target countries.     

Estimating flexible consumption functions for urban and rural households in China

There are few comprehensive studies of household consumption in China that covers all commodities due to data restrictions. This prevents the calculation of inequality indices based on consumption. This lack of coverage also makes analysis of policies that affect consumption difficult; economy-wide models used for analysis often have to employ simple consumption forms with unit income elasticities. We estimate a translog demand system distinguished by demographic characteristics, giving price and income elasticities that should be useful for policy analysis. We estimate separate functions for urban and rural households using household expenditure data and detailed commodity prices (1995–2006). This allows future analysis of social welfare and inequality based on consumption to supplement existing studies based on income. To illustrate an application of the model, we project consumption composition based on projected prices, incomes and demographic changes – aging, education improvement and urbanization.     

Food Demand Characteristics in Uganda: Estimation and Policy Relevance

Uganda was highly successful in reducing poverty over the past two decades but made little progress towards household food security. This underlines the need for designing food security interventions customised for household‐specific needs and behaviours. This study estimates Ugandan household demand behaviour with a focus on food consumption paying particular attention to household‐specific characteristics. The results show that preferences to increase calorie‐dense staple consumption, likely associated with food energy deficiency, extend far beyond the percentage of rural Ugandans officially deemed poor. Price elasticities indicate that poor rural households are largely well positioned to compensate staple price increases by substitution as long as they are not already concentrated on the cheapest foods. This flexibility applies less to urban households. The estimated demand elasticities generally vary widely between rural and urban households and depend on expenditure levels. Household‐specific characteristics have significant, sometimes pronounced, influences on demand, as do seasons and regions. The results reflect highly differentiated demand behaviour, which can be utilised to improve the design and evaluation of food security interventions.     

Retesting the Separability of China＇s Rural Households

This article retests the separability of China’s rural households in light of growing doubt about the sustainability of high economic growth in China.If a household’s production decisions are "separable "from the household’s consumption decisions,generally this suggests there is no surplus labor.Many scholars aver that China’s surplus rural labor has spurred rapid economic growth,but concerns have arisen as to whether China still has surplus labor available.We investigate this issue using rural household panel data from 1993 to 2009.The regression results confirm that households in rural China have progressed from being non-separable to separable.The estimation results for both the entire country and regions reject the separability hypothesis before 2004 but fail to reject the hypothesis after 2004(with the exception of the central region).These results suggest that China ’s surplus labor supply is dwindling,especially in the eastern and the western regions.The sustainability of China’s high economic growth is questionable in the absence of a large reservoir of surplus rural labor.     

Food away from home in Beijing: Effects of wealth,time and “free” meals

Based on a modified Becker household consumption and production model and newly surveyed data set collected by the authors, this study investigated household expenditure on food away from home (FAFH) and its determinants in Beijing, China. A Box–Cox double-hurdle regression is estimated. The key findings suggest that household expenditure on dining out might be significantly underestimated when using the data most commonly used in food consumption research in China. Excluding hosted meals that are not paid for by individual consumers comprises nearly one half of the underestimation. Meanwhile, this exclusion could bias estimates of income effects on the demand for food away from home.
