We illustrate how natural resource dependent and isolated communities manage their forest stock. Our model is based on field observations of the Eaglewood trade in Papua New Guinea. Using a dynamic model of household utility maximization and simulations, we analyze the impact of variations in the (monopsonistic) resource price on the households’ consumption choices and their allocation of effor...

Agricultural households use assets not only for production as a source of income generation but also for protecting consumption from negative economic shocks. We show a model of household dynamic decisions on investment in agricultural productive assets under credit constraints and non-convex production technology. We test and estimate the model with data from Kagera, Tanzania in order to show ...

In this paper we present an endogenous growth model with productive public capital and pollution. As to pollution we assume that it is a by-product of aggregate production and that it negatively affects utility of the household but not production possibilities directly. The paper studies the dynamics of the model and demonstrates that there exists either a unique balanced growth path which is a...

In this paper we study growth and welfare effects of fiscal policy in an endogenous growth model with public capital and environmental pollution. As to pollution we assume that it is due to aggregate production. Pollution does not have direct effects as concerns production possibilities but it only reduces utility of the household. The paper then studies growth effects of fiscal policy for the ...

Food-based approaches that focus on dietary diversification are effective strategies for reducing microand macro-nutrient deficiencies in malnourished populations. These approaches such as Helen Keller International‘s (HKI) homestead food production (HFP) model seek to improve the micronutrient intake of individuals, increase household food security, and advance women‘s empowerment. The standar...

in order to investigate effective factors on bread waste and determine effect genial of each factor on probability of being each family in three categories of low-medium, high and extra high bread waste, the order logit model and the 352 families data from mashad city were taken in use. the samples have been selected using a simple random sampling method. the survey of marginal effect in order ...

OBJECTIVE The association between farm production diversity and dietary diversity in rural smallholder households was recently analysed. Most existing studies build on household-level dietary diversity indicators calculated from 7d food consumption recalls. Herein, this association is revisited with individual-level 24 h recall data. The robustness of the results is tested by comparing househol...

To study the role of home production in life—cycle behavior, this paper creates a theoretical model in which both spouses in a couple allocate their time between market and home work. It then derives a pair of regression equations for estimating the parameters of the model, and it carries out the estimation using panel data on household net worth and lifetime earnings from the Health and Retire...

We consider the influence of household-based production on human capital investment. In data from rural Burkina Faso, we document a positive correlation between the presence of girls and enrollment that disappears in households that are able to send out or receive in children. We argue that the connection between education and the sex composition of co-resident children in households that are c...

background and objectives: lactobacillus delbrueckii ssp bulgaricus is widely used in dairy industries as a starter for yogurt production. this study was designed using response surface methodology (rsm) in 12 batch ph-controlled cultures of lactobacillus delbrueckii sub-ssp. bulgaricus for determining the effect of temperature and ph on the biomass production of a native strain of l. bulgaricu...
