“…Women in the low-income group had less varied diets than females in the higherincome groups, except for fish and fruit. Syrovátka (2003) examined the impact of the czech household income differentiation on the food expenditures using the Engel's expenditure functions. his research results confirmed the negative correlation between the level of the household incomes and the level of expenditures spent on such kind of food groups as fish and fish products, fruit and fruit products, fats and oils.…”

Abstract:The economy of the Slovak republic, as a part of the European economic area, is significantly determined by the world globalization process. one of the aspects, which globalization brings, is the social differentiation deepening between countries as well as across the particular countries. This phenomenon occurs in the Slovak republic also as a consequence of the increasing households' income differentiation. it is logical to assume that the household's members who live in the different living conditions behave differently in the commodity and service market due to different preferences. The purpose of this article is to quantify the influence of the household income differentiation on their behaviour in the food market. This market is divided into five separated food market groups according to the healthy Eating Pyramid. The share of the particular food groups' expenditures in the total household food expenditures is used as a representative of the household food purchase preferences. The results of the analysis did not confirm the assumption about the significant influence of the household income differentiation on the purchases of the particular food groups. The estimation of the Engel's expenditure functions and the food expenditures elasticities with respect to the income changes are used for quantification of the impact of the household income differentiation on the particular food groups' expenditures. The food expenditures elasticities referred to the income changes verified differences among the household behaviour in the food market. The food expenditures of the households with a higher income are less elastic regarding the income changes than the food expenditures of the households with a lower income.

“…These starting points make the household's decision-making process formally tractable and enable its precise mathematical formalization. This advantage of the neoclassical approach is demonstrated for example in Syrovátka (2003) by the analysis of the Engel's law validity within food expenditures. However, the agents usually do not know all possible events or their accompanying probabilities and the market forces generally cannot account for the unknowability and unpredictability of the future.…”

Decision-making process of households on food consumption

Decision-making process of households on food consumption is discussed in the post-Keynesian theory of household choice. Since the core assumption of uncertainty is employed, the set of consumption alternatives is restricted to the subset of the known ones. When searching for these alternatives, the consumer faces the search costs expressed by time of search. The sample of Czech households was investigated to ascertain the volume of the search and 57% of households do not seek for any information that are relevant for decision-making on foodstuff purchase. To overcome this activity, the households more likely rely on prices and the range of goods of the closest sellers to them. Searching for information on product is replaced by reliance on habits and recommendations of the others. On the contrary, the uncertainty of real purchase power is of lower significance in food consumption, because the foodstuffs meet the basic physiological needs and dispose of constrained stability in storage. Thus, households cannot always postpone (or bring forward) their consumption. In order to deal with the lack of money, households from lower income levels reduce their expenditures for foodstuffs more often than those from the higher income levels. Consequently, the relationship between the level of income and needs satiation is outlined.

“…Přímá dynamizace modelů sice zamezila vzniku zdánlivých regresí v analyzovaných vztazích z pozice trendové složky (Minařík, B., 1998), ale nedokázala eliminovat případný vliv pravidelně se opakujících výkyvů. Bohužel právě přítomnost periodické složky může vyvolat nežádoucí zkreslení zkoumaných Engelových vztahů, viz výsledky výzkumů v oblasti výdajů českých domácností za potraviny (Syrovátka, P., 2003). S vědomím této skutečnosti byla ve výchozích časových řadách (re t ), (rE t ), (rm t ) nejprve důkladně prošetřena periodická složka vývoje tak, aby mohlo být provedeno její případné odfiltrování.…”

The article deals with the analysis of the shape of the Engel's curve in the field of the expenditures for meat and meat products. Within the analysis, the paper is especially focused on the initial growth phase of the Engel's curve. The CSO data of the average Czech household was used for the research. For the elimination of the price impacts in this income-expenditure analysis, the original CSO data on nominal level were transformed into the real level. The studied real shares were determined with respect to the total food expenditures and also with respect to the total households' incomes. The linear and the quadratic forms of the dynamic Engels' models were developed for the aims of the research. Besides the trend development, the periodical component was investigated. Regression analysis was fully confirmed the validity of the Engel's law in the field of the Czech-household expenditures for meat and meat products. Furthermore, the quadratic model form showed the existence of the initial growth phase of the examined Engel's curve. In case of the real share with respect to the total food expenditures by the model:rw1t* = (–1,0176E – 08) · (rmt*)2 + (2,8498E – 04) · rmt* + [(–1,7011E + 00) + (1,3970E – 03) · t],the size of the real household income is 14 003 CZK. For the second analysed share of the real expenditures with respect to the total households’ incomes, the real level of the income by the developed model:rw2t* = (–2,8844E – 09) · (rmt*)2 + (7,8205E – 05) · rmt* + [(–4,6323E + 01) + (3,1095E – 04) · t]the value was 13 557 CZK.
