The objective of this study was to analyze consumers' fluid milk consumption and preference in Turkey by using cross-sectional national survey data. The Chi-square test of independence and multinomial logit procedure were used to investigate the selected socioeconomic and demographic characteristics of consumers that determine households' fluid milk consumption choices between unprocessed fluid milk, processed fluid milk and non-consumption choices. Empirical results indicate that unprocessed fluid milk preference is related positively to household size, number of children in family, household income, and age of housewife; and negatively to education level and employment status of housewife. On the other hand, processed fluid milk preferences are related positively to household income, number of children in households and education level of housewife and negatively to household size and age of housewife.

Based on the data, 47.8% of the households consume unpacked milk, 29.3% consume sterilized milk, and 7.9% consume pasteurized fluid milk at least once a month. Results of the multinomial logit model for fluid milk consumption behavior suggest that unpacked fluid milk preference is related positively to household size, income and age of the household head, and negatively to education level of the household head and status of the household wife. Similarly, pasteurized and sterilized fluid milk preferences are related positively to income and the education level of the household head, and negatively to household size and age of the household head. Results from these analyses are used to suggest techniques for marketing fluid milk products to specific segments of the consumer population.

Demand elasticities and PCM ratios were measured for 32 national branded and 14 private label products for 9 food categories by using Almost Ideal Demand System. According to the results, lower-income shoppers were more prices sensitive than higher-income shoppers and the average price elasticities were ranged between -1.96 (Snacks) and -3.33 (ice-cream). According to the results, non-collusive case gave smaller PCM than the Bertrand case and the average PCM ratios ranged from 27% for ice cream to 54% for chips.

Using data from the Turkish Household Expenditure Survey, the odds of smoking and spending level on tobacco products are investigated jointly. Statistical tests identify the inverse hyperbolic sine double-hurdle model as the preferred model. Socio-demographic factors are found to have differentiated effects on participation and level decisions. Findings can inform deliberations of policy measures to curtail tobacco consumption and reduce the costs of the public healthcare system.

Between 1994 and 2000, the share of total food expenditures spent on food away from home (FAFH) increased from 7 to 15% with an increasing share for fast-food facilities. This study focuses on whether demographic and socioeconomic factors have detectable effects on Turkish FAFH expenditures. This question is of interest because previous studies suggest that increasing household income, education, female labor participation and changing lifestyle especially in developing countries increased household FAFH consumption share but decreased food at home consumption share. However, no study to our knowledge has examined the combined effect of income, education, employment, and family status on Turkish FAFH consumption. The data for this research were obtained from personal interviews of representative sample households of the province of Adana in Turkey. The findings of this study generally indicate that restaurant facilities, employment of wife and education, composition of household, and income are statistically significant determinants of FAFH consumption.
Knowledge of a high correlation between a consumerÕs residence and his place of grocery shopping ... more Knowledge of a high correlation between a consumerÕs residence and his place of grocery shopping has allowed researchers to use scanner data to assess the relationship between income and shopping behavior. This study addresses the shopping behavior of over 100,000 consumers who patronize six supermarkets weekly. Three of these supermarkets are best characterized as stores that service primarily lower-income shoppers, and three are best characterized as stores that service primarily higher-income shoppers. A key objective of this research is to determine if purchasing patterns differ for the two income groups and, if so, to determine if these differences are consistent with economic theory. The results show that the dominant income group for a given area makes purchase decisions that are so widespread and prominent that the confounding effects of other income shoppers are completely overshadowed. Simply stated, the statistical evidence is so strong that it overcomes all possible deviating effects which may result from data outliers.
