Indonesia is one of the top coffee producers in the world. The major markets for Indonesian coffee are European Union (EU), then Germany is the largest importing country. This research analyzed the position for Indonesian robusta coffee in Germany among Vietnam and India as the major producers of robusta coffee as Indonesia. The econometric model of the Linear Approximate Almost Ideal Demand System was used to estimate a position for Indonesian robusta coffee among its competitors. The analysis utilized time-series data from 1996 to 2017. The results of the study showed that the main exporting countries, including Indonesia, tended to have lower import tariffs than other countries, not the main exporters. The demand for imported coffee beans was generally influenced by the prices of major exporters, but demand for imported roasted coffee was not affected by the prices of major importing countries. Indonesian coffee beans in the German market was elastic, while roasted coffee was inelastic. Indonesian coffee competed with Vietnam both for coffee beans and roasted coffee. The expenditure elasticity of Indonesian coffee beans was positive and Indonesian roasted coffee was negative.

Indonesia is the largest coffee producer in the world after Brazil, Vietnam and Colombia, but it was confronted with market problems. This paper, therefore, analysed the demand system as the position market for Indonesian coffee, either green bean or roasted coffee in the main importing countries such as Germany, Japan and The United States. The linear Approximate Almost Ideal Demand System (LA/AIDS) model was used to analyse the position of Indonesian coffee and its competitors. Time series data from 1996 to 2017 were obtained for the analysis. Empirical results indicated that most of the slope coefficients were statistically significant and in accordance with microeconomic theory. The variables of trade policy effected the Indonesian coffee trade. Indonesian green bean was found to be elastic in Germany, Japan, and The United States. Then, Indonesian roasted coffee was found to be inelastic in Japan. Indonesian green bean was a luxury good only in Germany, but Indonesian roasted coffee was an inferior good in Germany and The United States. Both Indonesian green bean and roasted coffee were a necessity in Japan. Almost Indonesian coffee substitute for Brazilian coffee and Colombian coffee, and complementary with Vietnamese coffee as its competitor.

The paper presents the results of a study that estimated the demand relations for primary oilseeds in South Africa.  The Error Correction version of Linear Approximated Almost Ideal Demand System (LA/AIDS)(ECM-LA/AIDS) were estimated.  Time series data for the period 1971-2002 were analysed.  Prior tests stablished weak searability between four oilseeds (sunflower seed, soybeans, groundnuts and cotton seed), indicating that these oilseeds should be modelled together.  The results suggest that the demand for oilseeds is negatively influenced by own price, which is consistent with economic theory, while positive long-term expenditure elasticities suggest that some oilseeds, notably sunflower seed and cotton seed, are luxury commodities in South Africa.

This study aims to analyze the integration of the Arabica and Robusta coffee markets in Indonesia with world coffee prices. The study uses secondary data in the form of annual time series data during the period 1985 - 2015. The study uses the VECM analysis method. This method explains the relationship of long-term dynamic equilibrium and short-term equilibrium in a system of equations. The analysis shows that Indonesian and world Arabica coffee is not integrated in the long term or the short term. In Robusta coffee VECM estimation analysis shows that there is a significant value at the 10% level in a long-term relationship with a value of 0.08579, which means that there is a short-term relationship between world Robusta coffee prices and domestic Robusta coffee prices in the previous year, but no relationship in the long run.

Fast and non-destructive indicators were evaluated as tools to measure the technological quality of Arabica and Robusta coffee. Accordingly, considering the roasting intensity in highly valuable commercial samples, volume, mass, apparent density, moisture, total ash, ash insoluble in hydrochloric acid, and ether extract were characterized. The chromatic parameters L*, C*, Hº were measured using illuminants D65 and C. It was found that in roasted coffee beans, the parameters L*, C*, Hº, and coordinate b* had an antagonist interaction due to an increase in the roasting intensity, whereas after milling, only L* and Hº decreased progressively. Considering that the parameters L* and Hº followed similar patterns using both illuminants, D65 and C, it can be concluded that they are appropriate to evaluate coffee colour changes during roasting, enabling a relationship with coffee quality.

<p>This paper estimates substitution in consumer demand for coffee product categories in Japan using the linear approximate quadratic almost ideal demand system model (LA/QUAIDS). Three expenditure shares and demand equations for coffee beans and powder (beans/powder), canned and bottled coffee (canned/bottled) and coffee drunk at coffee shops (coffee shops) are estimated for two or more person households in forty-nine cities for the period January 2000 through February 2015. The expenditure elasticity estimates indicate that coffee shops are luxury goods while beans/powder and canned/bottled coffee are necessities in the Japanese household. The demographic effects show that persons over the age of 65 and people who earn more consume coffee at coffee shops. Moreover, seasonal effects show demand for canned and bottled coffee as mostly positive while it is mostly negative for coffee drunk at coffee shops in most of the months. The findings of this study indicate that coffee product categories in the Japanese market are substitutes for one another, which is consistent with the reality of coffee consumption in Japan.<strong></strong></p>

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.
