OBESITY IN WESTERN EUROPE
Aim of paper:
Economic and econometric analysis of overweight and extreme overweight (obesity)
in Western Europe
Measure of weight: Body mass indexBMI = weight in kilo/(height in meters)2
![Page 3: TIME CONSTRAINTS, DURABLE CONSUMER GOODS AND THE PREVALENCE OF OBESITY IN WESTERN EUROPE Karsten Albæk.](https://reader033.fdocuments.net/reader033/viewer/2022051820/56649e355503460f94b24991/html5/thumbnails/3.jpg)
OBESITY IN WESTERN EUROPE
Idea: Analyze factors which affect energy balance intake of caloriesspending of calories
Time use of importance?
Durable consumer goods which affect time use:CarsMicrowave ovensDishwashers
Formal modeling: Becker’s analysis of time use
Extension: Take preferences of weight into accountDeviations from preferred weight enter intothe utility of the agents

OBESITY IN WESTERN EUROPE
Data: European Community Household Panel
Questions about weight and height 1998-2001
10 Western European countries: 5.500 to 21.500 males in each country
ditto for females
Pooled sample: about 107.000 males105.000 females

OBESITY IN WESTERN EUROPE
Econometric analysis:
OLS results for each countryMeasures the impact of covariates on average BMI
Quantile regression for pooled sampleMeasures the impact of covariates on differentquantiles of the weight distribution

OBESITY IN WESTERN EUROPE
Comments, effect of car possessionMales: Positive impact in all countries
(significant in 6 out of 10)Females: Positive impact in 3 countries (none significant)
Hypothesis, as most households in Europe only have one car:The male mostly uses the carAs the female does not use the car as much as the male, the car has no detrimental effect on the weight of the
female

Comments, effect of possession of a micro wave ovenNorthern Europe: Positive and significant effect on weight
for both males and females in 4 out of 6 countriesSouthern Europe: No effect in 3 out of 4 countries
(only a positive and significant effect for Spanish males)
Hypothesis: different use of the micro wave oven, for example Northern Europe: Used to heat ready prepared food Southern Europe: Heat milk for cappuccino

OBESITY IN WESTERN EUROPE
Comments, effect of possession of a dishwasher18 out of 20 coefficients are negative6 coefficients are significantly negative
Fact: a dishwasher is an extremely time saving deviceWashing up by hand after a family of 4
takes often more than ½ hourThis time could be used for something else
Hypothesis: the time saved is used on something that reduces weight problems (for example making food instead ofwarming up ready prepared food)

Comments, effect of not working full time:Males: The coefficients are negative for all countries
(significantly negative in the 4 Southern Europeancountries)
Females: Mixed results 3 positive and significant coefficients1 negative and significant coefficient
