Multinomial Logistic Regression
Opis:
This study analyzed the factors affecting the level of commercialization among households owning cattle. The study was conducted at the Makhado Local Municipality of Vhembe District, Limpopo Province, South Africa. The study sampled 150 households owning cattle from five villages within the municipality. Data were collected through a structured questionnaire that was administered face-to-face to the respondents. For empirical reasons, the study used two analytical techniques, namely; Household Comecialisation Index and Multinomial Logistic Regression Model. Empirical results reveal that eight variables were significant in affecting the level of commercialization among households owning cattle. These variables are the marital status of household head, the age of the household head, source of income, the occupation of household, access to market information, distance to the nearest market, membership to farmer organization, and land size. Based on the findings of the study, several policy recommendations were proposed, namely; Encouragement of youth participation in agriculture in general and in cattle production in particular, promotion of gender equality in decision-making, households’ farmer organization, encouragement of market-orientation in cattle production, and establishment of cattle input support programs (e.g., feed, water and disease control).

Opis:
This study assessed the different income generating activities as well as factors that influenced choice of such activities among forest communities in Cross Rivers State of Nigeria. One hundred copies of structured questionnaire were used to obtain information from respondents in the study area. Two Local Government Areas (LGAs) were purposively selected for the study, due to their agrarian and forest-based nature. Five communities were then randomly selected from each of the LGAs and ten copies of questionnaire were randomly administered in each community. Both descriptive statistics such as frequencies and percentages as well as inferential statistics such as Multinomial Logistic Regression were used in the study. From the study, it was discovered that the average household size, age, farm size and household income were 4; 36.5; 1.75Ha and N39, 330 respectively. It was also observed that the respondents engaged in different income generating activities which are then categorized into On-farm only activities, Non-farm only activities as well as Non-farm+ On-farm activities. Thirty-seven percent (37%) of the respondents engaged in only farming activities with only 20% of them engaging in non-farm activities alone; while 43% of the respondents combine farm activities with non-farm activities. The results of the Multinomial Logistic Regression show that age, educational qualification, access to extension services, total household monthly income, farming experience, farm size as well as availability of forest were variables that significantly influenced the respondents’ choice of livelihood strategies at 5% level of significance.

Opis:
This study was carried out to estimate the extent of food security and its determinants among rural households in Nigeria. Data for this study was obtained from 180 rural households consisting of 1260 members through the use of a structured questionnaire. Data was analyzed with a descriptive technique and a less restrictive multinomial logistic regression model. The result found most rural households to be food insecure as they measure high on the food insecurity scale. Age, gender, marital status, access to credit, dependency ratio, household size, ownership of farmland and farming experience significantly influence food security categories. The study concluded that: female-headed married households were more food secure than male-headed households; an increase in age of household heads makes it more likely to be food secure, and so does access to credit facilities; conversely, an increase in family size and in the dependency ratio makes it less likely to be food secure. The study recommends that there should be provision and proper monitoring of credit facilities to small farmers in other to increase their scale of operation and improve their food security status. Also, adequate attention should be given to policy measures that address family planning in order to reduce the household size to a level the household heads can adequately cater for.

Opis:
The main objective of this paper was to determine the factors that affect the livelihood strategies of resettled smallholder farmers in Zimbabwe. The study was conducted in Manicaland Province in Zimbabwe, and the respondents were stratified into four groups. These were smallholder farmers resettled under the A1 and A2 models, as well as tobacco and non-tobacco smallholder farmers. The two models differ in how they were implemented and supported, which might lead to them having different livelihood strategies. A total of 300 respondents were surveyed, consisting of 114 tobacco and 149 non-tobacco farmers and 24 off-farm and 13 wageearner households in Manicaland province. The study used a Multinomial Logit model to investigate the factors influencing a household’s decision to choose different livelihood strategies. In the model, the dependent variables included four livelihood strategies, while the explanatory variables included various household social-economic and institutional factors. The results obtained from the multinomial logistic regression model established that gender and land size were significant at a level of 1%, and education, household size, access to credit and access to inputs were significant at 5% in the adoption of tobacco farming, access to credit and gender were significant at a 1% level in the adoption of non-tobacco farming, while education was significant at a 10% level in adopting off-farm were found to be significant in determining the adoption of the tobacco farming in the study area up to less than 10% probability level in adopting off-farm activities. Smallholder farmers who did not adopt tobacco farming indicated that limited land size, shortage of labour and access to tobacco inputs were the major impediments to adopting tobacco farming. The government should support the efforts of smallholder farmers to increase their livelihood strategies through unveiling credit lines for farming activities. Access to inputs for smallholder farmers should be made a priority by the government through the provision and fair distribution of adequate agricultural inputs.

Opis:
Binomial logit models are commonly used in the analysis of the situation of respondents on the labour market. Consequently, in most cases researchers consider two states: of being unemployed and employed or economically inactive and active. This paper focuses on the situation of young people aged 18 to 29 on the labour market in Poland. A major part of the people who comprise the studied group are still in education or combine education with work. Therefore, the participants of the research were divided into the following groups: the employed and not learning, those combining education with work, the unemployed, learners/students only, and those economically inactive and not at school. The model allowing an analysis which includes both the most common division into working and nonworking persons as well as the division proposed in this study is a nested logit model. This model has a hierarchical structure and is a special case of a multinomial logit model. In this paper, all models were estimated within the Bayesian approach. The findings show that continuing education by young people may result from their problems with finding a job; moreover, combining work with education is not the preferred form of professional activity. In addition, the study examines the inequalities observed on the Polish labour market.

Opis:
This paper addresses the issue of participation in additional activities in foreign languages among Polish students aged 7–15. Foreign language skills are important in recruitment to secondary school and university. In the labour market, there is also a considerable wage premium for foreign language skills. Participation in such activities is therefore a form of investment in human capital. In this work we distinguish two kinds of additional foreign language activities: paid and free, and we show their different characteristics, which is our contribution to the literature. We check whether the key factors on the demand and supply side of additional activities such as family socio-economic status (SES) and size of the place of residence affect the participation in paid and free activities in a similar way. We also examine gender differences in additional foreign language activities participation. For the purpose of our analysis, we use data from the second round of the Determinants of Educational Decisions study (UDE) and apply the multinomial logit regression model. Our results indicate that family SES and size of the place of residence are important factors for probability of participation in paid foreign language activities. For participation in free activities, family SES does not matter. The-refore, these classes can contribute to equalising educational opportunities. We also find that girls are more likely to participate in both paid and free activities in foreign languages.

Opis:
Regardless of the several measures implemented by the South African government to curb food insecurity, majority of rural households are still experiencing food insecurity at a provincial level in Limpopo Province. This could be because of the high unemployment rate that the rural households are experiencing at a provincial level. As many of the rural households’ members went as far as obtaining tertiary education, most individuals still find it difficult to secure jobs and this results to many rural households depending on social grants for a living. In addition, social grant money alone does not become enough to meet their entire families’ food needs. The study was conducted at Mopani district municipality. Multistage sampling procedure was used, and the villages were selected based on probability proportionate to size. Thus, making the total of 173 rural households. The objectives of the study were to profile the socio-economic characteristics of rural households and to identify food security status of rural households and to determine factors that influence food security among rural households. To analyse the data, Household food insecurity access scale, descriptive statistics and Multinomial logistic regression model were used. From the findings of the study, the results revealed that majority of rural households in Mopani district municipality were found to be moderate to severe food insecure.

Opis:
This paper deals with the primary causes of informal housing in Greece as well as the observed differentiations in informal housing patterns across space. The spatial level of analysis is the prefectural administrative level. The results of the multinomial logistic regression analysis indicate that Greek prefectures differ in the way they experience the informal housing phenomenon. An explanation for the observed differences may be the separate development paths followed and the diverse range of economic activities in each prefecture. The Greek state has not made provisions for creating the necessary ‘urban land stock’ in each prefecture, so that everyone interested can find land parcels at an affordable price. On the contrary, the state encourages the informal housing activity by legalizing large areas of such activity sporadically and by introducing legislative initiatives of limited success in dealing with the problem.
