Technological improvements along with falling prices on photovoltaic (PV) panels and electric vehicles (EVs) suggest that they might become more common in the future. The introduction of distributed PV power production and EV charging has a considerable impact on the power system, in particular at the end-user in the electricity grid. In this PhD thesis PV power production, household electricity use and EV charging are investigated on different system levels. The methodologies used in this thesis are interdisciplinary but the main contributions are mathematical modeling, simulations and data analysis of these three components and their interactions. Models for estimating PV power production, household electricity use, EV charging and their combination are developed using data and stochastic modeling with Markov chains and probability distributions. Additionally, data on PV power production and EV charging from eight solar charging stations is analyzed. Results show that the clear-sky index for PV power production applications can be modeled via a bimodal Normal probability distribution, that household electricity use can be modeled via either Weibull or Log-normal probability distributions and that EV charging can be modeled by Bernoulli probability distributions. Complete models of PV power production, household electricity use and EV home-charging are developed with both Markov chain and probability distribution modeling. It is also shown that EV home-charging can be modeled as an extension to the Widén Markov chain model for generating synthetic household electricity use patterns. Analysis of measurements from solar charging stations show a wide variety of EV charging patterns. Additionally an alternative approach to modeling the clear-sky index is introduced and shown to give a generalized Ångström equation relating solar irradiation to the duration of bright sunshine. Analysis of the total power consumption/production patterns of PV power production, household electricity use and EV home-charging at the end-user in the grid highlights the dependency between the components, which quantifies the mismatch issue of distributed intermittent power production and consumption. At an aggregate level of households the level of mismatch is shown to be lower.

Paper [I]- Household Migration and the Local Public Sector: Evidence from Sweden, 1981-1984 (co-authored with Michael L. Wyzan), contains an empirical explo­ration of the nexus between variables related to the local public sector budget and migration. Micro-data is employed in binomial and multinomial-logit regressions esti­mating the probability to migrate. We report results separately for metropolitan and nonmetropolitan areas, because the per capita levels of the tax base and intergovernmen­tal grants are theoretically important migration determinants where population is sparse, while the tax rate may be more important where population is dense. Empirical results support our fiscal hypotheses and are consistent with previous findings on household characteristics. Paper [II]- Internal Gross Migration in Sweden: The effects of Variation in Mobility Grants and Regional Labour Market Conditions, focuses on the effects of labor market conditions and migratory stimuli on over county-border migration. Aggregate data on the flows of all migrants and on the flows of migrants receiving extra mobility stimuli are used in estimations of a single-equation migration model based on the hiring function. The results indicate that regional migration flows respond to changes in labor market conditions in accordance with predictions from economic theory. This result seems mainly to stem from the migratory behavior of the unemployed. In addition, nonmatching migration subsidies at the levels employed are not found to be migration enhancing. Paper [IH]- Employment Opportunities, Wages and Interregional Migration in Sweden 1970-1989, deals with the impact of aggregate labor turnover and regional labor market conditions on gross in- and outmigration. Annual panel data is used in estima­tion of separate in- and outmigration functions, where regional labor market conditions are assumed to be endogenous with migration under two different assumptions concer­ning the working of the labor market. An increase in the regional excess supply of labor is found to increase outmigration and decrease inmigration. Moreover, cyclical variation in labor turnover is positively correlated with gross migration. The hypothesized effects of real wages on migration are not confirmed. The results are not sensitive to the various assumptions concerning regional wage formation considered in this study. Paper [IV]- A Panel Study of Migration, Household Real Earnings and Self-Selec- tion (co-authored with Roger Axelsson). The effects of migration on household real earnings are examined. Data pertain to a sample of stable household constellations in Sweden, 1978-1991. A treatment-effect model is employed, whereby the potential effects of nonrandom sampling of data on earnings for migrants and nonmigrants are taken into account. We find that stable multi-adult household constellations did not gain in income from migration during the 1980s. In addition, we find no strong indications of selection bias in the income equation. / digitalisering@umu

The main aim of this study is to define the cooking activity spaces in Burgaz at 4th Century B.C. by carrying out statistical analysis of artefacts come from floor levels. In this study the distribution of artefacts and the associations of these distributions with architectural remains are examined rather than architectural features. In order to defining cooking activity spaces, the spatial distribution of cooking wares and utilities were taken into consideration. The distributions of cooking wares were tried to associate with ashy areas that can be related to cooking activities. In this study, the spatial analysis of archaeological artefacts assemblages that found in four well preserved houses from NE Sector revealed during the excavations of Burgaz (1993-2003) was carried out and the space usage, especially cooking spaces, were identified in these houses.

Urban land prices have important effects on urban development and locational distribution of land-uses. Housing is one of those sectors. There are high-density residential areas covering high-rise apartments at the city center where the land prices are quite high. Here, sizes of the plots and the housing units are relatively small. However, land prices begin to decrease with the increasing distance from the city center and the production of low-density, low-rise housing which is economically unfeasible at the center turns to be feasible for the housebuilders at the outskirts. Low-rise houses at the urban fringe provides various opportunities for the households. In these areas, plots and housing units are relatively larger due to cheap and available land. In addition to this, better urban services, quiet and clean environment as well as privacy contribute to create a livable urban environment. However, households living in low-rise housing units are subject to high transportation and maintenance costs. It is expected that they would compensate these costs with larger housing units, prestigious urban environment and many opportunities that their neighborhoods offer. Urbanization processes may be differ from one country to another with respect to the socio-economic and political structures, and the environmental characteristics. In that sense, low-rise housing areas at the urban fringe of Ankara were found to be developed highly compatible with urban land use theories / but different from the processes experienced in developed countries, to some extent. With regard to these, low-rise housing development in Ankara is discussed according to plan decisions, housebuilders, households and urban development pattern, considering the theoretical basis and historical processes.

Recent work in the area of retail financial services marketing almost invariably cite the deregulation of national and international financial markets as a major reason as to why financial institutions have a need for better knowledge of their customers' behaviors and needs. Among the most sought-after information are better ways to segment and target the market, that is, how do groups of households behave with regards to their savings and investments, why do they behave in certain ways, how can we reach them and how do they respond to marketing activities? In this thesis we will attempt to shed light on some salient aspects of the first two of these four questions.Three of the papers in this volume are based on the segmentation of the market for retail financial services based on different financial strategies, as expressed in households' portfolio choices. In the first two papers, such behavioral segmentation is carried out on data from samples of Swedish and Dutch households. Issues concerning the stability of segmentation over time are also highlighted. The third paper is also focused on the concept of heterogeneity, but this time as expressed by different agents within the individual household, the question being whether the marketing researcher needs to collect data from both spouses in family households. In the fourth paper behavioral segments are used as domains to examine differences in human intertemporal discounting. / Diss. Stockholm : Handelshögsk.

This thesis presents three essays on Malaysia’s poverty profile based on the Household Expenditure Survey (HES). The first and second studies were motivated by the shortcomings of the official poverty lines and poverty measurements. There are several conceptual and measurement problems related to evaluating the extent of poverty in Malaysia. The first study offers several alternative regional poverty analyses based on the consumption expenditure approach with varying underlying assumptions. The poverty lines are estimated using Ravallion-Bidani and Kakwani-Sajaia approaches and the consumption pattern of the 10th and 20th percentile per capita expenditure (PCE) households. Regional poverty lines based on Kakwani-Sajaia and Ravallion-Bidani lower bounds produced robust poverty measurement rankings across regions in the country for both the 10th and 20th percentile PCE households. However, for the 10th percentile PCE, Ravallion’s upper bound poverty lines do not produce robust poverty rankings. In relation to the shortcomings of the official poverty measurements, the second study analyses the economies of scale in consumption, specifically amongst poor households. Using the 10th and 20th percentile PCE households, the household size economies are estimated using specifications proposed by Deaton-Paxson and Kakwani-Son. The findings show that the economies of scale indices are sensitive to the selection of methods and sample groups. Economies of scale in poor household consumption are present for food, housing, clothing, furnishing, personal goods and miscellaneous goods. This study further suggests that these indices be used as complementary to the existing national poverty measurements. The final study provides new insights into the limited urban poverty studies and to the new dimension of urban poverty. Using logistic regression, the determinants are analysed using the new poverty lines estimated in the earlier essay. The test of robustness of the determinants is conducted through re-estimating the logistic regression using a range of poverty lines. The findings show that education, locational dimension, foreign migrant workers and household size are significant determinants of poverty in the urban areas.
