Historical background
“Call your men back, let them return from wherever they migrated to, andtell them that finally there will be jobs for them, here.”E.Mattei, 27.10.1962.

The research question
Has intensive exploitation of oil fields and greater resource revenues inBasilicata, all else equal, led to a higher degree of regional economicdevelopment?

Contribution
1 Estimate the economic effect of oil in the region of Basilicata duringthe period 1980− 2009, compared to control regions.
Synthetic Control Method (SCM) (Abadie et al. 2014): weight controlregions to construct a counterfactual that replicates the treated regionbefore treatment.
2 Discussion about channels.
Control rights; Organized crime; Sectoral effects; Labor migration.

Empirical Strategy
Identification strategy: exploit the fact that Basilicata producedthroughout the period of analysis a fraction close to unity of oilextracted in the 5+ 1 southern Italian regions.

Implementing the SCM: generating weights
SCM Algorithm: define GDP per capita as Y and its determinants X,such as:
Population, Labor Force, Gross Fixed Investment, Pop. shares byeducation level, Value Added shares of GDP by Industry.
Matching period (1980− 1998): Y pre0 and X0 in DP; Ypre1 and X1 in
treated unit.
Post-treatment (1999− 2009): Y post0 in DP; Y post1 in treated unit.
SC unit is given by the vector of weights W ∗ = (w1, ...,w5) (withw1 + ...+ w5 = 1) chosen as W that minimizes
k
∑m=1
vm(X1m − X0mW )2
in which vm are weights assigned to the m− th determinant.Roberto Iacono (Institute) No blessing, no curse? Oxford, 22.08.2015 10 / 32

Control rights structure
Brunnschweiler and Valente (2013): Int’l Partnership is linked tohigher GDP levels than Domestic/Foreign Control, regardless ofpolitical regime type.
Brunnschweiler and Valente (2013)’s coding of Italy: Foreign1930− 1956 and 1995− 2008, Partnership in between.
Q: would have Italy (and Basilicata)’s GDP benefited fromPartnership?

The plague of organized crime
Pinotti (2012): exposure to mafia activity (proxied by increase inmurders) after 1970s lowered GDP per capita by 16% in the treatedunit (Basilicata-Apulia), as compared to control group.
Q: can we rule out that public royalty revenues in Basilicatarepresented a profit opportunity for criminal organizations?

VAi ,t = value added (% of GDP) for sector (..) in region i , year t.
γi = region fixed effects.
δt = time fixed effects.
