Food Budget

While Malawi’s per capita cereal production may be higher than her per capita cereal consumption, Malawi is a net cereal importer and thus food insecure. The food situation is much worse in Malawi’s prisons because inmates generally eat one meal per day.The general objective of this study was to determine food budget shares and elasticities for the food stuffs commonly eaten in Malawi’s prisons. Using structured questionnaires in face to face interviews, the study collected data from 1000 prisoners and 30 officers-in-charge from all prisons in the country. The data was analysed using Stata 12 and employed the quadratic almost ideal demand system (QUAIDS) model as an analytical tool.Results from the analysis showed that budget shares for maize and beans were high as reflected by the fact that 86.5 per cent of the prison food budget was spent on these two food items while 6.8 per cent was spent on meat and vegetables. Maize was inelastic while meat, beans and salt were elastic with the own-price elasticity for meat being the highest. Expenditure elasticities for maize, meat and beans, at above unity, showed that these food items were luxuries in Malawi’s prisons.

While Malawi’s per capita cereal production may be higher than her per capita cereal consumption, Malawi is a net cereal importer and thus food insecure. The food situation is much worse in Malawi’s prisons because inmates generally eat one meal per day.The general objective of this study was to determine the importance of farms in Malawi’s prisons by comparing food insecurity in prisons with farms to that in prisons without farms. Using structured questionnaires in face to face interviews, the study collected data from 1000 prisoners and 30 officers-in-charge from all prisons in the country. The data was analysed using Stata 12 and employed the probit and the Foster-Greer-Thorbecke (FGT) models as an analytical tools.Results from the analysis showed that practically all prisoners in Malawi’s prisons were food insecure. There was a higher perception of food insecurity in prisons without farms than there was in prisons with farms. Conditions of severe food insecurity were experienced more in non-farmed prisons than in farmed prisons, and more prisoners in non-farmed prisons depended on food brought to them from their homes. Food insecurity was more prevalent in prisons without farms than in prisons with farms.

This paper analyze the food consumtion base-on animal protein in Lebong. The study estimated a demand model for food base-on animal protein by using Almost Ideal Demand System (AIDS) model. It also estimated demand elasticities for different food items by the models.  The result show that the demand model for food-based on animal protein can be explained by AIDS models. The model is consistent with demand theory. The coefficient of determination show range from 12.59 percent to 29.36 percent. However, the homogenity test for restriction parameters have not been explained by the model.  The estimated own-price elasticity of demand for Chicken, Goldfish and Egg indicated that if the price fell by 10% then the demand for the items would increase by 2.72%, 6.82%, and 9.05%, respectively. It show that the items are inelastic and necessities goods.  The income elasticity of demand for Chicken, Goldfish and Egg were 1.000, 0.999, and 1.000, respectively. It shows that all commodities are normal goods.  The estimates of cross price elasticity indicate that substitution effects of price change were not quite strong. Key word: food consumption, animal protein, AIDS model.

Tulisan ini bertujuan untuk menganalisis faktor-faktor yang mempengaruhi permintaan produk ikan penduduk Indonesia dan menduga elastisitas harga dan pendapatan beberapa kelompok ikan menurut kelompok pendapatan. Data yang digunakan adalah data SUSENAS 2008 modul konsumsi rumahtangga yang diperoleh dari Badan Pusat Statistik. Metode multistage budgetting approach dengan pendekatan model QUAIDS (Quadratic Almost Ideal Demand System)digunakan dalam penelitian ini. Hasil analisis menunjukkan bahwa pendugaan permintaan dengan model QUAIDS memberikan hasil cukup baik. Nilai dugaan koefisien sistem permintaan ikan menunjukkan bahwa semua peubah berpengaruh signifikan terhadap fungsi permintaan kelompok ikan dengan nilai koefisien determinasi sistem 67,3%. Dugaan koefisien peubah wilayah perkotaanperdesaan, peubah jumlah anggota rumah tangga, serta peubah dummy wilayah kepulauan semua bertanda positif. Nilai elastisitas pengeluaran ikan terhadap total pengeluaran pangan untuk semua kelompok pendapatan lebih besar dari dari satu (elastis) dengan kisaran 1,7 sampai 3,9; nilainya semakin kecil dengan semakin meningkatnya pendapatan. Elastisitas pengeluaran kelompok ikan terhadap total pengeluaran ikan semua juga bertanda positif dengan nilai berkisar dari 1,1 sampai 2,9. Hal ini menunjukkan bahwa keempat kelompok ikan yang dianalisis merupakan barang normal. Bila pengeluaran rumahtangga untuk seluruh ikan naik 1%, maka permintaan terhadap kelompok ikan yang dimaksud akan naik sebesar hampir 3%. Elastisitas harga kelompok ikan segar dan ikan awetan pada semua kelompok pendapatan bertanda negatif dengan nilai berkisar dari -0,4 sampai -0,8; sedangkan elastisitas harga untuk udang/hewan air lain (bukan ikan) yang diawetkan adalah -1. Tittle: Analysis of Demand for Fish in Indonesia: A Quadratic Almost Ideal Demand System (QUAIDS) Model Approarch.This study aimed at determining various factors affecting fish consumption patterns of Indonesian households, estimating income and price elasticities for different fish categories according to income groups. National Social and Economic Survey 2008 data were used in this study. and formulating policy directions to increase consumption of fish. Household consumption/expenditure data collected by Central Beaureu of Statistics in 2008 were used in this study. Multistage budgetting approach method with QUAIDS (Quadratic Almost Ideal Demand System) model was used in this study. Results of the analysis show that estimates parameters of demand for fish using QUAIDS model were a relatively good. Estimates value of fish demanf system were significantly affected on fish group demand function with determination coefficient of 67,3%. Dummy coefficient of urban-rural, family size and isloand region were a positive sign. Fish elasticity to the total food expenditure for all income group were greater than 1 ranging from 1,7 to 3,9; the magnitude of elasticity tends to smaller with the increase in income group category. Elasticity of fish group expenditure to the total fish expenditure were a positive sign ranging from 1.1 to 2.9. This indicates that all four fish group are considered a normal good. As total fish expenditure of the household increased by 1%, quantity demang for fish group increased approximately to 3%. Price elasticity of fresh and reserved fish were a negative sign ranging from -0.4 to -0.8; while price elasticity of preserved shrimp and other animal water (non fish) were -1.

While Malawi’s per capita cereal production may be higher than her per capita cereal consumption, Malawi is a net cereal importer and thus food insecure. The food situation is much worse in Malawi’s prisons because inmates generally eat one meal per day.The general objective of this study was to determine the effect of smaller prisoner numbers at a prison on the inmates’ access to food. This was done by comparing food insecurity in small prisons with that in big institutions. An institution housing less than 400 inmates was considered a small prison while one housing more than 400 prisoners was considered a big institution. Using structured questionnaires in face to face interviews, the study collected data from 1000 inmates and 30 officers-in-charge from all prisons in the country. The data was analysed using Stata 12 and employed the probit and the Foster-Greer-Thorbecke (FGT) models as analytical tools.Results from the analysis showed that practically all inmates in Malawi’s prisons were food insecure. There was, however, a higher perception of food insecurity in big prisons than there was in small ones. Conditions of severe food insecurity were experienced more in big institutions than in small ones, and more inmates in big prisons depended on food brought to them from their homes. Food insecurity was more prevalent in big prisons than in small ones.

The first difference version of the restricted source-differentiated almost ideal demand system is used to estimate South Korean meat demand. The results of this study indicate that the United States has the most to gain from an increase in the size of the South Korean imported meat market in terms of its beef exports, while South Korea has the most to gain from this expansion in the pork market. Moreover, the results indicate that the United States has a competitive advantage to Australia in the South Korean beef market. Results of this study have implications for U.S. meat exports in this ever-changing policy environment.

The market of wooden beds in the U.S. has been flooded with imports from China and Vietnam in recent years. Static and dynamic Almost Ideal Demand System models are used to assess the import demand for wooden beds from the top seven supplying countries. The analyses reveal that the antidumping investigation on China has some temporary trade depression effect on China, but trade diversion occurs to Vietnam, Indonesia, Canada, and Brazil. The formal implementation of antidumping duties since 2005 has not shown any significant effect on the trade pattern. U.S. consumers spend more on beds from newly industrialized countries and there are moderate degrees of substitution among wooden beds from most countries.
