Engel's approach to consumption plays an important role in theoretical economics. There is thus strong empirical and theoretical interest to analyze the cross-section Engel function of real populations. A prerequisite of any economic interpretation is a reasonable estimation of these curves from given cross-section data containing households' expenditures and income. In submitted paper the Engel curves computation was applied on the Slovak household's income and expenditure. A double-log specifi cation of the Engel's function has been chosen in order to estimate the expenditure elasticity of households by using an economic status of households' head at work for each household by children per person. The household Budget Survey of the Slovak Statistical offi ce was used for the period 2004-2014. Analysis of income elasticity demonstrated negative correlation of food expenditure in Slovak households and the number of children in all food groups of the consumer basket classifi ed as necessary goods. Examination of the households based on the economic activity of their head (employee, self-employed, retired, and others) showed differences in availability of various food groups for the households (inferior, necessary, luxury goods). Increased amount of food groups were included within the luxury category in following order: the households with self-employed head, employed household head, and retirees. Households without children have meat and fats & oils included in the category inferior goods, other types of households according to the number of children considered all types of food in the consumer basket as necessary goods. Results provide deeper knowledge about consumers' behavior of Slovak households.

Exists plenty of the theoretical and empirical literature on what determines consumption levels over time and across countries, but less research into changes in consumption patterns. To better understand how changing incomes and prices influenced consumption patterns, we estimate Almost Ideal Demand System models. Aim of the paper is to find patterns and preference changes in the consumer demand for foodstuff in Slovakia. From the methodological aspect we used important items of the demand and for consumers behavior analysis we computed elasticity coefficients by using model AIDS. Computed elasticities showed that all foodstuff items had a positive income elasticity of demand.

The aim of the paper is to explain beef consumption through the economic indicators and the prediction tendencies of beef consumption. There are countries like Slovakia that confirm the opposite trend despite the global trend of consumption growth. In terms of the ecosystems' sustainability, beef production should be adjusted accordingly, as in the case of Slovakia. We focus on the economic aspect of beef consumption from the perspective of sustainability. Commodity prices are considered to be a significant factor influencing consumption and the behaviour of beef consumers. Despite increasing income in Slovakia, consumption of beef covers only 30% of recommended doses in the year 2018. To achieve the objective of the research, we decided to use the calculation of price and income elasticity of food demand using the Almost Ideal Demand System (AIDS) model to analyse meat consumption trends. The findings confirm that beef consumption will decline in Slovakia in the following years, and it will be progressively replaced by pork and poultry meat.
