Three essays on applied methods of regional development analysis
No full textLa tesi si compone di tre capitoli indipendenti volti allo studio dello sviluppo
economico e all’analisi d’impatto a livello regionale. I primi due capitoli si occupano
della regione Valle D’Aosta e utilizzano due metodologie applicate per l’analisi dello
sviluppo regionale in prospettiva storica e la valutazione degli effetti di alcuni
potenziali scenari di sviluppo sull’economia locale. Il primo capitolo utilizza il
metodo dei moltiplicatori contabili ottenuti da due matrici di contabilità sociale
regionali (SAM) costruite con riferimento agli anni 1963 e 2002. Il metodo impiegato
permette di analizzare i cambiamenti strutturali avvenuti nel territorio nel
quarantennio considerato. L’analisi rivela le caratteristiche principali dell’economia
regionale e i principali cambiamenti avvenuti ponendo un’attenzione particolare
all’integrazione tra settori e istituzioni regionali e alla capacità di ricezione e
trasmissione degli interventi di politica economica. La matrice di contabilità sociale
del 2002 viene successivamente utilizzata per simulare alcuni scenari di sviluppo volti
a valorizzare le principali risorse della regione suggerendo interventi per promuovere
la diffusione di tecnologie avanzate e la creazione di sinergie tra le imprese. Il
secondo capitolo sviluppa un modello regionale di equilibrio economico generale
dinamico calibrato utilizzando entrambe le matrici di contabilità sociale regionali.
Viene proposta una calibrazione storica tale per cui il modello inizializzato al 1963 è
in grado di riprodurre le condizioni economiche osservate 40 anni piú tardi. Questo
processo di calibrazione permette di determinare i tassi di crescita della produttività a
livello di settore. La validazione storica del modello, attraverso il confronto dei
risultati ottenuti con delle serie storiche di dati reali riferiti al valore aggiunto per
settore, allo stock di capitale regionale e al totale degli investimenti, permette di
valutare i limiti e la capacità di previsione del modello. Il metodo proposto permette
inoltre di condurre un’analisi controfattuale storica che non è possibile con i modelli
classici di equilibrio economico generale dinamici. Il modello viene infine utilizzato
per l’analisi degli effetti di due scenari volti all’analisi del comportamento della
pubblica amministrazione regionale. Il terzo capitolo propone un modello di
equilibrio economico generale multi-regionale per valutare gli effetti della riforma
della politica agricola comune del 2003 sulle tre macro-aree Nord, Centro e Sud
d’Italia. Il modello pone un’attenzione particolare sul settore agricolo suddiviso in 22
categorie. A differenza dei modelli di equilibrio generale utilizzati in letteratura per
l’analisi dell’impatto della riforma della politica agricola comune dove l’analisi si
basa sull’assunzione che i beni agricoli siano prodotti su tutto il territorio, il modello
proposto in questo capitolo considera la distribuzione regionale delle attività agricole
e l’eterogeneità delle famiglie nel territorio. L’impresa famigliare agricola è
considerata come un modello di equilibrio generale in miniatura dove, come sequenza
delle imperfezioni di mercato, in particolare della imperfetta sostituibilità tra lavoro
familiare e salariato, le decisioni di consumo e produzione non sono separabili.
Questo porta alla determinazione di un salario endogeno, indicativo del costo
opportunità del lavorio familiare, che differisce tra le regioni e quindi permette di
tener conto dell’eterogeneità delle imprese familiari nelle tre macro-aree. Un altro
aspetto innovativo riguarda la modellizzazione del commercio interregionale che
contribuisce a chiarire gli effetti complessivi della riforma sull’economia regionale. I
metodi proposti in questa tesi sono facilmente trasferibili alle amministrazioni locali e
possono quindi facilitare il processo di capacity building istituzionale.This thesis consists of three self-contained essays devoted to the analysis of regional
development and policy issues. The first two essays share a focus on the Italian region
Valle d’Aosta and employ two alternative applied methods for the analysis of the
regional historical development and the impact of alternative policy scenarios. The
first essay uses the multipliers obtained from two regional social accounting matrices
(SAM) for the years 1963 and 2002 to compare the current economic conditions with
those observed in 1963. This analysis reveals the core characteristics and the changes
occurred during the observed period with a focus on the level of integration and
responsiveness to policy interventions of local sectors and institutions. The 2002
SAM is used to simulate several scenarios which stress the importance of the main
regional resources and suggest interventions to foster the diffusion of advanced
technologies and promote synergies within local enterprises. The second essay
develops a regional dynamic general equilibrium model calibrated using the two
regional SAMs above mentioned. A historical calibration procedure is performed over
the 40 years period to obtain the sectorial total factor productivity growth rates so that
the model outcomes reasonably match the actual value added by sector in 2002. A
validation exercise ensures that the modelled tendencies closely approximate the
actual observed growth patterns of the main regional macroeconomic variables. This
dynamic general equilibrium model provides an original and powerful tool for
historical counterfactual analysis not available using standard dynamic general
equilibrium models. The model is used to compare the growth path followed by the
region during the considered period with different scenarios intended to explore the
effects of alternative behaviours of the regional administration. Finally, the third essay
develops a multi-regional general equilibrium model (MEG-R) to compare policy
effects across the three Italian macro-regions: North, Centre and South. The model
focuses on the agricultural sector and is used to evaluate the impact of the Common
Agricultural Policy (CAP) reform. In contrast with most of the general equilibrium
models adopted, where the impact analysis is based on the assumption that all crops
are produced in all regions, this model takes into account the territorial distribution of
agricultural activities. Moreover, while it is common to model the representative farm
using a unique aggregate production technology separated from the consumption
decisions, this model incorporates the link between the production and the
consumption side of the farm household allowing for heterogeneous household
behaviour across regions. A further contribution is in the modelling of interregional
trade flows of agricultural commodities which exploits the current available
information and helps to assess the regional implications of the reform. The applied
methods proposed in this thesis are highly transferable to local and regional
authorities and can facilitate the process of capacity building of territorial institutions

Crop diversification and child health: empirical evidence from Tanzania
No full textMalnutrition is recognized as a major issue among low-income households in developing countries with long-term implications for economic development. Recently, crop diversification has been considered as a strategy to improve nutrition and health. However, there is no systematic empirical evidence on the role played by crop diversification in improving human health. We use three waves of the Tanzania National Panel Survey to test the effect of crop diversification on child health. We implement two instrumental variable approaches, and perform several robustness checks to address potential endogeneity concerns. We find a positive but small effect of an increase in crop diversification on child height-for-age z-scores, through greater dietary diversity. The effect is larger for subsistence households and children living in households with limited market access

No full textMalnutrition is recognized as a major issue among low-income households in developing countries with long-term implications for economic development. Recently, crop diversification has been recognized as a strategy to improve nutrition and health, and as a risk coping strategy used by farmers in the face of climate change. However, there is no systematic empirical evidence on the role played by crop diversification in improving human health. We use the Tanzania National Panel Survey to investigate the effects of crop diversification on child health. We use fixed effects panel estimation to control for unobserved heterogeneity, and perform several robustness checks including placebo tests to test the validity of our findings. We find a positive and significant effect of crop diversification on long-term child nutritional status, in particular for very young children and children living in households with limited market access

Social Networks and Renewable Energy Technology Adoption: Empirical Evidence from Biogas Adoption in China
No full textWe provide novel empirical evidence on the association between social networks and the adoption of renewable energy technology. We distinguish between two main transmission mechanisms through which social networks can affect renewable energy technology adoption: information diffusion and social influence. Using data primarily collected from rural China on biogas adoption, we find that both mechanisms are at work. In addition, we find that information spreads through trusted network members, such as friends and family, while social influence is mainly exercised by government officials. Government officials are more likely to promote the adoption of technology by leading by example rather than by spreading information
Un'analisi dello sviluppo della Valle d'Aosta in prospettiva storica con l'ausilio delle matrici di contabilità sociale
No full textQuesto saggio descrive lo sviluppo economico della regione Valle d'Aosta in prospettiva storica attraverso l'impiego dei moltiplicatori contabili ottenuti da due SAM regionali riferite al 1963 e al 2002. L'attuale struttura economica viene confrontata con le condizioni osservate agli inizi degli anni '60; il metodo permette di analizzare i cambiamenti avvenuti con particolare attenzione al grado di integrazione dei settori e delle istituzioni locali e alla capacità di ricezione e trasmissione delle politiche regionali. La SAM del 2002 viene utilizzata per condurre alcune simulazioni con l'obiettivo di valutare scenari di sviluppo volti a valorizzare le risorse principali della regione
A regional dynamic general equilibrium model with historical calibration: a counterfactual exercise
No full textThis paper develops a regional dynamic general equilibrium model calibrated using two regional SAMs for the Italian region Valle D'Aosta for the years 1963 and 2002. A historical calibration procedure is performed over the 40 years period and ensures that the modelled tendencies perfectly reproduce the actual observed growth patterns of the main regional macroeconomic variables. The dynamic general equilibrium model provides an original and powerful tool for historical counterfactual analysis not available using standard dynamic general equilibrium models. The model is used to compare the growth path followed by the region during the period of interest with a counterfactual scenario intended to evaluate how the region would have performed in the case of a contraction of the transfers from the national government to the regional government and the families
