<em>One of commodity which is important to be fulfilled is fruit. From producer side, it has been available much in Lampung Province but has not been utilized optimally by consumer. This study purposed to analyze the factors influencing fruit demand and the response of demand changes due to shifting of price and income. The analysis was conducted by using AIDS (Almost Ideal Demand System) model and the parameter was estimated by using SUR (Seemingly Unrelated Regression) method. The results stated that the fruit demand was influenced by the fruit price (either own-price or cross-price), expenditure, and the number of household members. The elasticity shows that the own-price for all kinds of fruit is inelastic. The cross-price elasticity indicates that there are some fruits that have substitution or complementary relationship among them and in all types of fruits, income elasticity has positive sign.</em>

Households consume animal protein after carbohydrate food is fulfilled, moreover animal protein prices are increasing. This study aims to analyze the effect of rising beef prices on demand. The demand system approach uses the Quadratic Almost Ideal Demand System (QUAIDS) model. Estimation of parameters using Iterated non-linear Seemingly Unrelated Regression. The research data use the 2016 National Socio-Economic Survey (Susenas, 2016), amounting to 10,751 households. The results of the study concluded that beef is the third most elastic animal food after fresh fish and chicken meat. Fresh fish in the most elastic among all animal foods with a demand elasticity of 3.31%, followed by chicken, beef, milk powder, and eggs with demand elasticities of 1.55%, 1.62%, 1.29%, and 0.80%, respectively. Beef is a luxury item with an income elasticity of 1.59%, as well as fresh fish, chicken meat, and milk powder. While eggs are normal goods. Although fresh fish is more elastic than beef, beef marginal expenditure share (MES) is higher than fresh fish MES, so that in the long run, the increase in household income tends to increase beef consumption more than fresh fish.

The purpose of this study is to investigate the spending behavior of Thai tourists in Dan Sai District, Loei province, Thailand by applying the Almost Ideal Demand System (AIDS) model. The analysis was conducted by employing Seemingly Unrelated Regression Estimation (SURE). A questionnaire was used to collect data and 400 samples were collected. The results revealed that the price factor influences the cost of accommodation on other expenses, food and beverage expenses on other expenses and travel expenses on other expenses while the revenue factor influences travel costs on other expenses and the cost of souvenirs on other expenses. The results of the study show that there should be measures to stimulate tourist spending using price strategy to encourage tourists to spend more, and marketing strategies should be used to encourage high-income tourists to spend in Dan Sai District.

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.

Objectives: We reviewed the current status of healthy eating behaviors in South Korea and analyzed the influencing factors. Methods: A single-equation robust estimator and a seemingly unrelated regression were completed for the effects of access to food retailers, single households, and patients living in the household on healthy eating. Data were retrieved from a consumer survey of 3043 household members preparing food. Results: Better access to retailers is positively related to healthy eating status. Single households are least likely to practice healthy eating and the presence of a patient in the household is negatively related to healthy eating status. Conclusions: The 3 factors have significant effects on South Koreans' healthy eating status.

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.
