Using 2002-2006 Household Budget Survey, this thesis investigates the income, consumption and saving dynamics of Turkish households within a life-cycle theory framework by employing cross-sectional analyses and cohort techniques. Cohort techniques are used not only to analyze these variables, but also to investigate the demographics and components of income and consumption. The analyses are deepened by dividing the sample according to the location of the households (urban-rural areas), and significant differences are found between urban and rural households, especially in terms of saving behaviors. Income, consumption and savings of formal and informal households are also investigated. Analyzing these households provides information regarding the precautionary saving since the higher income uncertainty of the informal households is expected to force them for extra saving due to precautionary motive. Finally, the life-cycle model and the precautionary saving hypothesis are tested by estimating log-linearized Euler equations. In the test of precautionary saving hypothesis, formal-informal data are used as a proxy for the risk variable. According to the estimation results, the predictions of the life-cycle model do not hold for Turkey but there is no evidence that this is due to precautionary saving.

The overall objective of the study was to analyse the Forest Dwelling Systems in the Terra Firme and Várzea communities and to investigate the conditions under which the different activities are allocated across households. In this study, the Farming System Approach facilitates a holistic examination of the Forest Dwelling Household System. This study broadly analyses the importance of natural products and their role as consumption and as goods for cash income for forest dwellers. By focusing on the functions of those products, their role within the Forest Dweller System must be examined. There have been identified differences between the Terra Firme (upland) and Várzea (floodplain) ecosystems management and production systems that are still ignored by decision makers. The study area was identified based on certain criteria: a) accessibility to the area (field support), b) availability of the forest production and, c) ecosystem (Terra Firme and Várzea communities). The survey was conducted in one community at the Terra Firme region (Itacoã) and in three communities at the Várzea region (Monte Tabor, Nova Santa Cruz, Manoel Carneiro). In selecting the households, the dependence on extraction of forest resources as the principal source of income was used as the major criteria, and part-time households were excluded from the studies. In order to obtain data on the structure of the entire Forest Dwelling Household System, productive activities within the house garden, cropping and forest extraction, financial and marketing aspects, were analyzed in 60 households (48 in Terra Firme and 12 in Várzea communities). Data concerning demography, socio-cultural aspects, labour force, land tenure were also gathered and analyzed. For this purpose households and key informants were interviewed with the use of a semi-structured questionnaire; participative observation was carried out and market research was executed. The households live basically to sustenance. A purely subsistence oriented family can only be identified as such if its production objectives are merely meant to fulfil subsistence needs. The type of forest dwelling household system existing in the region is strongly marked by small-scale production; the involvement of unpaid family workers in the production process; the combination of the incomes earned from on-, out- and off-farm activities and, to a limited extent, these households live under the threat of poverty. According to the results of the household financial analysis it could be stated that the main financial characteristics of households are the following: a) they are poor and have little ready cash; b) loans to them are usually unavailable; c) they are conscious of an uncertain environment, of cash shortage, and of household responsibilities and therefore are risk-averse; d) they often suffer cyclical labour shortage and under-employment; e) they are economically rational but not necessary profit maximising because they have their own scales of utility. The results of the analysis led to one priority goal, ranked as such by all the households, which was to satisfy the family?s sustenance, namely to supply sufficient food and provide housing for the family at all times. Only when food supply is guaranteed households will think of how to generate cash from their farm, in order to satisfy other needs which are part of an improved standard of living. Commercializing production does not come as a desire to maximize profit, but rather a need to generate cash income for subsistence purposes.

<p>The aim of this study was to examine the relations between women’s perceived stress off the job (dependent variable), responsability for household chores, emotional support, number of children living at home, neuroticism and age (independent variables). Comparisons between the present sample and two independent samples from previous research were made with regard to perceived stress and neuroticism. The sample of this study consisted of 186 women working in the fields of health care and geriatric care. The results showed that perceived stress correlated positively with neuroticism and number of children and negatively with emotional support, though the effectsizes for number of children and emotional support were fairly small. Neuroticism was the strongest predictor for perceived stress. Implemented comparisons showed that the present sample reported significantly higher levels of perceived stress and neuroticism than the two independent samples.</p><p>Keywords: women, perceived stress off the job, responsability for household chores, emotional support, number of children, neuroticism, age.</p>

Abstract In the 1980s the cinematic nuclear family flourished again after the self-explorative 1960s and turbulent 1970s. This thesis explores the portrayal of the idealized American family in film between the 1950s and 1980s. The 1955 film Rebel Without a Cause reflects the 1950s cinematic family model. My investigation includes the role of the father figure and the bonds in intergenerational relationships. During the early 1980s, films such Ordinary People and ET: The Extraterrestrial reflect the need to reevaluate the 1950s ideal nuclear family. My examination of these films continues to include the importance of the father figure and bonds between child and parents along with contemporary elements such as the use of psychiatry and rise of single-parent households. These movies' redefined portrayals of the idealized nuclear family represent the shifting dynamics of modern society in terms of single-parent households and highlighted importance of intergenerational relationships.

Water quality and availability are important issues in many developing countries where portions of populations still lack access to potable water. Throughout the English-speaking Caribbean and parts of Latin America, households and businesses invest in water supply systems even when they are connected to and pay for water services from a private or state owned provider. Inconsistent supplies of water from the water companies have led many people to invest in storage tanks which, if operated correctly, can provide water throughout the day even when the supply from the main is low or zero. While these individual systems help to guarantee a more constant supply of water, they may impact water quality when it does reach the household tap. The tanks could become breeding grounds for vectors of human disease and may also affect the concentrations of bacteria, heavy metals and organics in the water. The goal of this research was to understand how households use water storage tanks and determine the effect of these tanks and the individual practices on water quality. Target plots were used to visualize linkages between water quality parameters and household surveys of localized water practices and perception on water quality. The study focused on three field sites: Siparia, Trinidad and Tobago, Region 4 Subset in Guyana, and Villa Litoral, Bolivia. Convenience sampling was used to administer surveys to households in the rural areas of Siparia (39), Region 4 Subset (40), and Villa Litoral (57). The Region 4 Subset is comprised of two rural areas, Mon Repos and Mocha, and Georgetown, the country's capital. Black, high-density polyethylene (HDPE) tanks and water storage drums are predominantly used in the field sites within Siparia and Region 4 Subset, while cement tanks, drums, and jerry cans are used in Villa Litoral. The average age of household water storage devices was 4-10 years in Siparia and Region 4 Subset, and 0- 3 years in Villa Litoral. These devices were found on various elevations to accommodate piped connection, indoor pumping, and rainwater catchment. Cleaning frequency of tanks in Siparia was every few months, while in Region 4 Subset it varied from weekly to every few months. In Villa Litoral 26.3% of the population surveyed cleaned weekly and 38.6% cleaned annually. Disinfection of water sources was practiced by 30% of residents in Siparia and 60% of residents in the Region 4 Subset. While disinfection was practiced, issues with frequency and correct dosage led to inadequate disinfection. Eighty-four percent of households in Siparia and 50% of households in Region 4 Subset disinfected on a monthly or quarterly basis. Of the households that did disinfect, the bleach and/or disinfectant used was allowed to mix for at least 30 minutes in 50% of households in Siparia and 91.6% of households in the Region 4 Subset. Disinfection was not practiced by the majority of households in Villa Litoral. With regards to health, 15% of households in Region 4 Subset and 40.4% in Villa Litoral reported recent waterborne illnesses among house members. Water samples were taken from households in Siparia (24), Region 4 Subset (40), and Villa Litoral (26). The majority of households in all three communities relied on piped water from their respective main pump. Those who were not connected to piped water relied on rain water. In the Region 4 Subset, 18% of samples tested positive for fecal coliform and 45% for total coliform. In Villa Litoral, 85% of samples tested positive for fecal coliform and 100% for total coliform. The majority of samples from all three communities exceeded the WHO guideline values for lead (0.01 mg/L) and iron (0.3 mg/L). This was most likely due to the material used in the household plumbing and distribution pipe infrastructure as these could leach. Five indicators (chemical and biological water quality, reach of risk, storage device, female involvement, and household belief) were conveniently projected on target plots to link the results from water quality assessments with reported household practices and beliefs. The greatest risk factors seen were poor water quality and household beliefs like the security of water storage containers and safety of stored water, perceived water description and pressure, and access to water safety media.

Recent research suggests that, besides traditional socio-demographic and built environment attributes, the attitudes and perceptions of parents toward walking and bicycling play a crucial role in deciding their children’s mode choice to school. However, very little is known about the factors that shape these parental attitudes toward their children actively commuting to school. The current study aims to investigate this unexplored avenue of research and identify the influences on parental attitudes toward their children walking and bicycling to school, as part of a larger nationwide effort to make children more physically active and combat rising trends of childhood obesity in the US. Through the use of a multivariate ordered response model (a model structure that allows different attitudes to be correlated), the current study analyses five different parental attitudes toward their children walking and bicycling to school, based on data drawn from the California add-on sample of the 2009 National Household Travel Survey. In particular, the subsample from the Los Angeles – Riverside – Orange County area is used in this study to take advantage of a rich set of micro-accessibility measures that is available for this region. It is found that school accessibility, work patterns, current mode use in the household, and socio-demographic characteristics shape parental attitudes toward children walking and bicycling to school. The study findings provide insights on policies, strategies, and campaigns that may help shift parental attitudes to be more favourable toward their children walking and bicycling to school. / text

Economists have rejected the popular view that time use is primarily influenced by local customs and law, and instead argue that it is determined by optimal choices of economic agents and the market mechanism. However the analysis of time allocation has been focused on the labor-leisure choice problem which posits a worker who wants more leisure because of his preference for leisure over work. Thus going beyond the standard model, these essays add to the theory of the economics of time use. First I examine why married men earn more. I explore the possibility that differences in household work by marital status can explain the observed male marital wages advantage. Depending on the type and timing of household work, I segregate it into flexible and inflexible household work, using the American Time Use Survey. Empirical results provide strong support for the productivity difference between married and never married men. Household work has significant negative and differential effects on wages. The effects are not only driven by total time spent on household work, but also by types and timing of household work. The result shows that inflexible household work has a stronger negative effect on wages than flexible household work. Second I study how taxes affect time and goods allocation in home production. I claim that an increase in sales taxes encourages households to substitute away from the market goods input in favor of untaxed non-market time input. I explore the substitution response by relating household market purchases and time use. The theory part shows that the size of elasticity of substitution between market goods input and time input is crucial for understanding the government's optimal tax policy. Then I show that it is optimal to impose lower taxes on goods used in the production of commodities with a higher elasticity of substitution. In the empirical part, I estimate sizes of elasticities of substitution of goods for time with the combined survey of Mexican household consumption expenditures and time allocation for 2002. I find that the elasticity of substitution for 'Eating' is lowest. Finally wage compensation for climate is examined. Using the Merged Outgoing Rotation Group File from 2002 to 2007, I find that the North-South wage differential in construction and extraction occupations is much higher than in any other occupations. I claim that this is because weather affects wage determination. If individuals are to locate in both desirable and undesirable locations, undesirable locations must offer higher wages. Using the O*NET database, I obtain information on how often an occupation requires exposure to weather conditions. Estimation results of the wage equation show that wage compensation for living in bad weather amounts to 11.9 percent of hourly wages evaluated at sample means. The difference in wage compensation for working in bad weather between the most exposed (outdoorness index = 5) and least exposed (outdoorness index = 0) occupations is estimated to be 9.6 percent of hourly wages evaluated at sample means. In addition, I find that the occupational injury risk is related to weather conditions in the case of construction and extraction occupations. / text

Since doi moi, Vietnam has made remarkable achievements in many frontiers. However, much effort needs to be done to further improve social and economic sectors, particularly in the context of increasing the number of uncertainties. In analyses using household surveys from Vietnam, this dissertation finds that there are discrepancies between monetary and multidimensional measures of poverty in the same time period and as well as over time. The results also show that an additional shock is not always important but physical and human assets are vital determinants of a household's poverty dynamics. Additionally, coping strategies are useful for households to recover from shocks. However, it is not always easy to identify the effects of coping strategies independently from other effects. The findings of this dissertation contribute to the increasing discussion of the discrepancies between monetary and multidimensional poverty, of the vulnerability to poverty, and of the resilience against shocks. They are also useful for evaluation and assessment of poverty alleviating policies in developing countries.

The importance of access to modern energy has been well understood by governments and donor agencies in many developing countries, and significant effort has been made in recent years to address energy access challenges. However, despite these efforts, the International Energy Agency (IEA) has predicted that the energy access problem will remain unresolved by 2030. Therefore, adequate and appropriate action is needed to resolve this problem more quickly. This dissertation analyses policies and their impacts and will help researchers and policy makers in developing countries to (i) understand the impact of policies in the formation of a renewable energy (RE) market, (ii) consider the determinants of technological choices when promoting access to energy services and, (iii) better appreciate the sustainability performance of rural energy. For the purpose of analysis, several country cases from Asia and Sub-Saharan Africa region were carried out as these are the two main regions where the energy access problem are most acute. To understand the impact of policies in the formation of RE based rural electrification market, a case study was conducted in Nepal. The study has shown that rural electrification has been expanding as a consequence of market-oriented policies. When it comes to selection of electrification path-ways, different technological alternatives are analysed in Afghanistan and Nepal, taking levelized cost of electricity (LCOE) as the means to select cost effective options. The analysis has presented best-fit conditions for these various technological pathways in the two countries and verified whether they are following the appropriate and cost effective course in their efforts to expand rural electrification. For understanding the determinants of cooking fuel choices and to analyse policy implications in the transition of large populations from traditional to modern fuels, fuel choices are modelled in the case of China. Choices are modelled (using MESSAGE–ACCESS mod-el) with standard economic variables such as income, technology costs and fuel prices, along with some unique variable such as inconvenience costs. Future access scenarios are designed considering different policy options to accelerate the transition. Sustainability is one of the key concerns in terms of energy access. This dissertation introduces methods for evaluating (i) the sustainability performance of energy technologies and (ii) the status and progress of developing countries in providing sustainable energy access. Different sets of sustainability indicators are considered for the rural energy sector and aggregated to form a single composite index. The energy technology sustainability index (ETSI) is used for assessing the performance of different energy technological systems in the case of India. The analysis reveals that mature technologies such as biomass gasifiers, biogas and micro hydro have relatively better sustainability performance among the options considered, while solar and wind, though showing fairly good improvement in sustainability performance, still have difficulties competing with more mature and conventional technologies without policy support. The Energy Sustainability Index (ESI) has been applied to China, India, South Africa, Sri-Lanka, Bangladesh and Ghana between 1990 and 2010 to evaluate the status and progress made by these countries in rural energy sustainability. The analysis suggests that South Africa’s rural energy sustainability index is highest followed by China, Sri Lanka, India, Bangladesh and Ghana respectively. The rural energy sustainability has improved relatively over time in all countries except Ghana. The dissertation shows that policies are helping the rapid expansion of the RE market though with uneven penetration in rural Nepal. Access to credit and cumbersome subsidy delivery mechanism are perceived as the major factors affecting the expansion of rural electrification, requiring innovation. The electrification pathways taken by Nepal seem functional and moving in the right direction but some flaws in the delivery mechanisms require attention. Meanwhile in Afghanistan, pathways are not well defined and the country lacks a clear-cut national policy framework for the expansion of rural electrification. The analysis on fuel transition shows that even a fast developing country such as China will continue to have serious problems guaranteeing the access to solid fuels for cooking for one third of its rural population by 2030. The problem could be more severe in poorer nations. There-fore, further policy intervention addressing the high implicit discount rate of the poorer section of the population, reducing the upfront cost of more efficient technology (stoves) or the costs of cleaner fuels with subsidies must be considered to promote energy transition. Overall, this dissertation has analysed key issues in the global discussion about sustainable energy access. The methods for sustainability assessment suggested have been specially designed for rural settings in developing countries and are instrumental to assess the performance of rural energy technologies and track the progress of sustainable energy access efforts among rural households. / <p>QC 20140210</p>
