LA COMPARAZIONE CROSS-NATIONAL• GLI STUDI DI CASI E L’APPROCCIO PER
VARIABILI• metodi qualitativi vs. quantitativi nella
macrosociologia comparata• Explanatory factorsEconomic (growth & technology)Cultural (social norms and values)Institutional (political system and
organisations)1
STUDI DI CASI• olismo non radicale• nazioni = configurazione storico-sociale unica e
complessa,ma• accettabile astrarre caratteristiche/ attributi,
che possono esser comparate- variabili identificate implicitamentema - mantenuta identificabilità dei casi• metodo della concordanza e della differenza• carattere logico → proposizioni deterministiche
2
Case-oriented approach
- Focus on how phenomena are working in each case
- Country = case considered as a “whole”
- Qualitative variables are often stressed
- (Very) few country-cases
3
APPROCCIO PER VARIABILI• sfida alla pretesa storicista• nazioni = uniche,• comparazione olistica impossibile • obiettivo: sostituire i nomi delle nazioni
con quelli delle variabili• ogni nazione caratterizzata da un valore
di variabile dipendente e di variabili indipendenti
4
Variable-oriented approach
- Focus on relations between variables
- Country = set of items of variables included in the analysis
- Usually quantitative variables (data- bases)
- A large number of countries
5
PROBLEMA DEI PICCOLI NUMERI• limitato numero di casi → modelli sovra
determinati con insufficienti gradi di libertà• ma non può essere risolto da studi di casologica di Mill • presuppone - inclusione di tutti i fattori causali- assenza di interazioni tra fattori• implica- società governata da leggi deterministiche- dati raccolti privi di ogni errore
6
IL PROBLEMA DI GALTON= mancanza di indipendenza delle
osservazioni nazonali• correlazioni istituzionali potrebbero
sorgere• non da processi interni a società,• ma essere risultato di processi di
diffusione culturale/politica tra società
7
IL PROBLEMA DI GALTON• riguarda solo studio comparativo delle
politiche pubbliche (pressione delle organizzazioni internazionali e della internazionalizzazione dell’economia)
• è possibile incorporare nell’analisi i processi responsabili di interdipendenza
• introdurre idea di “famiglia di nazioni”• Confini e limiti della macrosociologia• Processi intersocietali vs. intrasocietali
8
IL PROBLEMA DELLA SCATOLA NERA
= come si passa dalle inferenze descrittive a quelle causali
• analisi quantitativa cross-national dice poco sui processi e le azioni sociali alla base delle relazioni tra variabili empiricamente individuate
occorre• avere un resoconto “casualmente adeguato”
del modo in cui sono generate tali regolarità9
IL PROBLEMA DELLA SCATOLA NERA
non bastano• sequenza di eventi storici• assemblaggio di induzioni, • ridescrizione di regolarità empiriche
all’interno di struttura concettualetroppo spazio per spiegazioni ad hoc• un resoconto teorico deve avere pretesa di
generalità• teoria generale = applicabile in contesti sociali
molto lontani nel tempo e nello spazio10
Macro-variable-oriented approachMerits• Easy availability of national average
data allows exploratory analyses on many countries, also for long periods.
Limits• Number of countries often restricted
for statistical methods (regressions).• Choice of countries can undermine
the results.• Macro-relations may not be confirmed
at the micro level.11
12
Two easy examples concerning the choice of countries
1. Cross-national relation between penalisation of women and their labour market participation.
2. Cross-national relation between female employment and the proportion of part time.
Women in the labour market: at a cross-road between cultural norms, socio-political institutions, economic growth.

The underlying hypothesisWomen are more penalised in societies that are less accustomed to regarding their participation in the labour market as fully normal by social standards (gender culture: mother vs. worker).ButSuch a hypothesis is grounded on the choice of countries where labour market participation of women was growing over time at least since early Seventies

The different story of former planned societies
Near full employment also for women in planned societies; then transition caused a more or less important decrease of women activity rate and increase of unemployment, both for women and men.In those countries, long time fully accustomed in regarding women as workers, their (recent) penalisation followed idiosyncratic pathways.

The underlying hypothesisSince early ’70s, growth in % part time paralleled growth of women employment in all Western countries (but Italy till early ’90s).Part time pushed women employment because it let also poorly educated (and more family-committed / poorly paid) women to get a paid work.So, women are more employed in countries where opportunities for part time jobs are larger.

The different story of former planned societies
In those countries also poorly educated women were accustomed to being fully employed in full time jobs.When transition caused a more or less important decrease in their employment rate, the proportion of women in part time jobs remained very low and cross-nationally followed idiosyncratic pathways without any relation with their labour participation.
Societal analysis approach- Micro-macro analysis- Two steps:1. stressing relations between
variables inside any country (also at individual level)
2. cross-national comparing the results of those relations
Quali/quantitative variables (recently also longitudinal)
22
Societal analysis approach- Medium number of countries- Standardised data-sets are
neededUsual outcomes = typologies• - un/employment models• - labour market systems• - welfare regimes
23
Cross-national variation in youth unemployment
Variation in total unemployment rate among EU countries is important, but more important is variation in penalisation of youth vs. prime age people.Ratio of youth/adult unemployment rates ranges from 1.1 to 3.6
24
The connection with the strictness of the labour market regulation
• Oecd tried to cross-nationally relates
- unemployment rate to EIP → failure
- youth/adult unemployment rate to EIP
→ failure
25
26
Educational system’s role in the transition from school to work
• Vocational education → signalling a job seeker for a job → reducing seeking time
• General education→ no signalling function
• Where vocational education prevails, impact of high EIP is counterbalanced
