� Classical view. Informality is the result of segmentation i.e. exces of labour supply(Harris & Todaro 1970).Workers have no choice than to create an "informal" market !
� New Evidence:Informality may also be avoluntary status

The drawbacks→challenges:
� Exit or Exclusion are explained by different theoretical approaches� Hard to (empirically) identify excluded from non excluded informals
(subjective surveys and only a few exist)
+ This paper’s methodology explains/proposes :
� How an existing unifying theoretical framework may nest both (exit andexclusion)

� Homogeneous productivity across workers� Workers receive job (wage) offers at random frequencies∼ Pλ
if λ → ∞⇒ perfect competition equilibrium� Two groups of workers with heterogenous information availability:
λ1 < λ2
Main implications:
Workers with less information stay at lower paid or less satisfactory jobs
This paper suggests :
� Workers atλ1 → segmented ones from Harris and Todaro model
Thus, Excluded workers may be identified to the group with lessinformation availability λ1

But other empirical evidence supports these findings Ernst (2008) :
� Structural change in Brazil’s labour market since the early90’s, caused asystematic increase of the lower and middle skilled labour demand
� It also increased the urban unemployment rates : urban unemployment≈ 10% rural unemployment≈ 1%

� Estimated parameters reflect the structural shocks in the labour market(education and urban→R)
� From labour status probabilities given exclusionP [S|R] :
� Education unambiguously reduces exclusion at any labour status� The estimated share of excluded within the informal sector≈ 70%� Exclusion mainly affects informality and unemployment
