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.

Currently, animal protein consumption in Indonesia is still low. The consumption of animal protein is one of the keys to improving public health. This study aims to analyze the consumption of animal protein shown by consumption of meat, chicken, fish and milk commodities in households in Indonesia. Fifth Indonesia Family Life Survey (IFLS) data applied by model of Almost Ideal Demand System (AIDS). The results found that the own-price elasticity has a negative sign in accordance with the law of demand. Cross-price elasticity values vary from one another. Expenditure elasticity has positive sign indicates that all commodities are normal goods. ========================== Saat ini konsumsi protein hewani di Indonesia masih relatif rendah. Padahal konsumsi protein hewani menjadi salah satu kunci untuk meningkatkan kesehatan masyarakat. Penelitian ini bertujuan untuk menganalisis konsumsi protein hewani yang ditunjukkan oleh konsumsi komoditas daging, daging ayam, ikan-ikanan, dan susu pada rumah tangga Indonesia. Penelitian ini menggunakan data Indonesian Family Life Survey (IFLS) 5 yang diaplikasikan dengan model Almost Ideal Demand System (AIDS). Hasil penelitian menunjukkan bahwa koefisien elastisitas harga sendiri memiliki tanda negatif sesuai dengan hukum permintaan. Nilai elastisitas harga silang bervariasi satu sama lain. Elastisitas pengeluaran bertanda positif menunjukkan bahwa seluruh komoditas merupakan barang normal.

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.

Objective: To identify the factors affecting the demand for berries in Mexican households, as well as the behavior in face of variations in economic income. Design/Methodology/Approach: In order to analyze the demand, microdata were used from the National Income-Expenditure Survey of Households 2018 (Encuesta Nacional Ingreso Gasto de los Hogares, ENIGH) from the National Institute of Statistics and Geography (Instituto Nacional de Estadística, Geografía e Informática, INEGI), and for its modelling the Almost Ideal Demand System (AIDS) model was used. Results: Because of their Marshallian elasticity, berries are an elastic good (-1.0316), and because of their expenditure elasticity they are a luxury good (1.0691). In terms of crossed Marshallian elasticities, sweet fruits and sugary beverages were identified as substitute goods with elasticity of 0.0013 and 0.0380, respectively, while semi-acid fruits and melons would be complementary goods, with elasticities of -0.0191 and -0.0184, respectively. Study Limitations/Implications: Given that most of the time series of the berries lack disaggregation and sufficient information, it is difficult to analyze each component of the group separately; therefore, it was decided to analyze the group of berries and its relationship with other goods; in addition, the ENIGH database was selected, which provides more information. Conclusions: There are state differences in the response to changes in prices and income with regard to the demand for berries, so that facing a generalized increase in household income consumption would increase much more in the center of the country than in the south-southeast.

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.

Jumlah rumah tangga sumber data yang dianalisis dalam penelitian ini berjumlah 839 rumah tangga.  Hasil penelitian menunjukkan secara parsial harga ikan, harga daging sapi, pengeluaran rumah tangga, wilayah geografi, dan jumlah anggota keluarga berpengaruh terhadap pangsa pengeluaran untuk produk ikan-ikanan, daging ayam, dan daging sapi. Elastisitas permintaan harga permintaan untuk ikan, daging sapi, dan daging ayam masuk dalam kategori inelastis, elastisitas pendapatan untuk daging sapi dan daging ayam masuk kategori elastis, dan ikan mempunyai elastisitas pendapatan yang inelastic. Kata kunci: model Almost Ideal Demand System (AIDS), elastisitas harga permintaan, elastisitas silang, elastisitas pendapatan. Abstract: Elasticity Analysis for Three Animal Protein Resources in Indonesia. This study aimed to analyze the behavior of household demand on three sources of animal protein (fish, beef, and chicken) were associated with different household characteristics and analyze the response of households in Indonesia to changes in price and income on the consumption of fish, beef, and chicken. Almost Ideal Demand System (AIDS) was adopted in this study, using data from the Indonesia Family Life Survey wave 4 (IFLS 4). Total number of the household analyzed in this study amounted to 839 households. The results showed that partially price of fish, beef prices, household expenditure, geographic region, and number of family members affect the share of expenditure fisheries products, chicken, and beef. The results implied that Price elasticity of demand for demand for fish, beef, and chicken were categorized as inelastic. While the income elasticity for beef and chicken were elastic, furthermore income elasticity for fish was inelastic. Keywords:  Almost Ideal Demand System (AIDS) model, demand price elasticity, cross elasticity of demand, income elasticity of demand.

Black soil is fertile, abundant with organic matter (OM) and is exceptional for farming. The black soil zone in northeast China is the third-largest black soil zone globally and produces a quarter of China’s commodity grain. However, the soil organic matter (SOM) in this zone is declining, and the quality of cultivated land is falling off rapidly due to overexploitation and unsustainable management practices. To help develop an integrated protection strategy for black soil, this study aimed to identify the primary factors contributing to SOM degradation. The geographic detector, which can detect both linear and nonlinear relationships and the interactions based on spatial heterogeneous patterns, was used to quantitatively analyze the natural and anthropogenic factors affecting SOM concentration in northeast China. In descending order, the nine factors affecting SOM are temperature, gross domestic product (GDP), elevation, population, soil type, precipitation, soil erosion, land use, and geomorphology. The influence of all factors is significant, and the interaction of any two factors enhances their impact. The SOM concentration decreases with increased temperature, population, soil erosion, elevation and terrain undulation. SOM rises with increased precipitation, initially decreases with increasing GDP but then increases, and varies by soil type and land use. Conclusions about detailed impacts are presented in this paper. For example, wind erosion has a more significant effect than water erosion, and irrigated land has a lower SOM content than dry land. Based on the study results, protection measures, including conservation tillage, farmland shelterbelts, cross-slope ridges, terraces, and rainfed farming are recommended. The conversion of high-quality farmland to non-farm uses should be prohibited.

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.
