5 Statistical blanks in data on European minimum wage sector Extant surveys cover limited number of countries (often the same)

6 Statistical blanks in data on European minimum wage sector Extant surveys cover limited number of countries (often the same) Statistical panoramas of minimum wage earners are outdated (and partial)

7 Statistical blanks in data on European minimum wage sector Extant surveys cover limited number of countries (often the same) Statistical panoramas of minimum wage earners are outdated (and partial) Few efforts to disaggregate the group of minimum wage earners

16 Typology of minimum wage systems

17 Typology of minimum wage systems Type 1 A single statutory minimum wage fixed at national level with no subsequent differentiation:

18 Typology of minimum wage systems Type 1 A single statutory minimum wage fixed at national level with no subsequent differentiation: clean cut system

19 Typology of minimum wage systems Type 1 A single statutory minimum wage fixed at national level with no subsequent differentiation: clean cut system Type 2 Many different minimum wages exist (specific sectors, regions, occupations, etc):

20 Typology of minimum wage systems Type 1 A single statutory minimum wage fixed at national level with no subsequent differentiation: clean cut system Type 2 Many different minimum wages exist (specific sectors, regions, occupations, etc): fuzzy system

21 Qualitative features of minimum wage systems

22 Qualitative features of minimum wage systems Main mechanism regulating minimum wages (government agencies, tripartite commissions, sectoral bargaining. etc.)

23 Qualitative features of minimum wage systems Main mechanism regulating minimum wages (government agencies, tripartite commissions, sectoral bargaining. etc.) Extension mechanism (erga omnes laws, selective extension laws, etc.)

24 Qualitative features of minimum wage systems Main mechanism regulating minimum wages (government agencies, tripartite commissions, sectoral bargaining. etc.) Extension mechanism (erga omnes laws, selective extension laws, etc.) Exempted categories of workers (civil servants, apprentices, etc)

25 Qualitative features of minimum wage systems Main mechanism regulating minimum wages (government agencies, tripartite commissions, sectoral bargaining. etc.) Extension mechanism (erga omnes laws, selective extension laws, etc.) Exempted categories of workers (civil servants, apprentices, etc) Differentiation of minimum rates (reduced rates for younger workers, people with disabilities, etc.)

50 Descriptive statistics (9 European countries, 2007)

51 Descriptive statistics (9 European countries, 2007) Level of minimum wages, share of minimum earners, and Kaitz indices per country

52 Descriptive statistics (9 European countries, 2007) Level of minimum wages, share of minimum earners, and Kaitz indices per country Individual characteristics of employees below and above minimum wages

53 Descriptive statistics (9 European countries, 2007) Level of minimum wages, share of minimum earners, and Kaitz indices per country Individual characteristics of employees below and above minimum wages Job characteristics of employees below and above minimum wages

54 Descriptive statistics (9 European countries, 2007) Level of minimum wages, share of minimum earners, and Kaitz indices per country Individual characteristics of employees below and above minimum wages Job characteristics of employees below and above minimum wages Distribution of minimum wage earners according to sector of activity

55 Descriptive statistics (9 European countries, 2007) Level of minimum wages, share of minimum earners, and Kaitz indices per country Individual characteristics of employees below and above minimum wages Job characteristics of employees below and above minimum wages Distribution of minimum wage earners according to sector of activity Household characteristics of employees below and above minimum wages

56 Weighted Kaitz index Clean cut systems : Hungary UK Ireland Poland Romania Bulgaria Spain Fuzzy systems : Belgium Germany 57.8 (19.0) Share of minimum earners

57 Logit model predicting likelihood of earning the minimum wage

58 Logit model predicting likelihood of earning the minimum wage Dependent variable: minimum wage dummy

59 Logit model predicting likelihood of earning the minimum wage Dependent variable: minimum wage dummy Independent variables: temporary work contract, part time, job change, tenure, occupational category, age, sex, education, firm size, sector of activity

60 Logit model predicting likelihood of earning the minimum wage Dependent variable: minimum wage dummy Independent variables: temporary work contract, part time, job change, tenure, occupational category, age, sex, education, firm size, sector of activity Separate individual-level regression for each of the nine countries

61 Descriptive statistics and logit regression:

62 Descriptive statistics and logit regression: Minimum wage earners on average younger, more feminine, less educated

63 Descriptive statistics and logit regression: Minimum wage earners on average younger, more feminine, less educated Proportion with temporary work contracts and part time work is on average higher among minimum wage earners

64 Descriptive statistics and logit regression: Minimum wage earners on average younger, more feminine, less educated Proportion with temporary work contracts and part time work is on average higher among minimum wage earners Size of effects differs across countries

65 Other results:

66 Other results: Minimum wage earners tend to live in bigger households, have lower disposable family income, and higher risk of poverty

67 Summary of results so far

68 Summary of results so far Updated, extended, and improved statistics on minimum wages

69 Summary of results so far Updated, extended, and improved statistics on minimum wages Diversity of minimum wage systems; co-existence of different rates in (almost) all countries

70 Summary of results so far Updated, extended, and improved statistics on minimum wages Diversity of minimum wage systems; co-existence of different rates in (almost) all countries Sign of effects for socio-demographic variables often similar across countries, but size of effects differ

71 Summary of results so far Updated, extended, and improved statistics on minimum wages Diversity of minimum wage systems; co-existence of different rates in (almost) all countries Sign of effects for socio-demographic variables often similar across countries, but size of effects differ Extensive infra-national variations in rates and employment spikes, notably among sectors of activity
