Abstract (english)

The traditional policy evaluation approach mainly focuses on one specific policy parameter, typically the treatment status, while less attention has been given to the mechanisms through which development program operates. On other hand, in recent econometric literature there have been some significant developments in untangling the mechanisms of economic agents behavior, they shed light on preferences and technology parameters that are invariant to policy changes.

The core of the thesis is to unlock the policy parameters in a unique World Bank programs in the challenging context of rural African economies, through acquiring knowledge about the causal mechanisms driving the change induced by the economic development policy. In the first part of the thesis, using a very unique setting of the World Bank infrastructure development program, I propose a strategy for the construction of building blocks that can be used as the ingredients of a structural system that explains the interconnection between the roads construction, access to markets and households' well being. I exploit the results from the innovative structural literature and apply them in under-developed economies setting, where standard economic theory often fails to explain the agents's behavior. The goal is to understand better the underlying developing economy principles, and to perform an ex-ante evaluation of the road construction on complex mechanisms of market exchange and welfare production function. This is interesting from both methodological and empirical point of view, as there are very few studies that apply newly developed structural econometric tools on real data. Moreover, in contrast to the carefully designed evaluations of many health and education initiatives in developing countries, our knowledge about the impacts of infrastructure projects has remained under-developed.

In the second part of this thesis, I use the setting of The Gambia Community Driven Development Program, to explore the endogenous social network formation, that defines the dimensions of the informal economic exchange. The objective of the research is twofold: conduct an empirical research on a very rich dataset on social networks in rural Gambia, using the setting of the Community Driven Program Evaluation (CDDP) and focus on the endogenous link formation. The second goal is to disentangle the effect of the program that operates indirectly on the probability of forming a link, through modifying the existing network attributes or modifying exchange preferences of individuals; thus find convincing way to identify the program effect on preferences.

Abstract (italian)

Il tradizionale approccio della valutazione delle politiche si concentra principalmente su un particolare parametro: in genere il treatment status, mentre una minore attenzione e stata volta verso i meccanismi attraverso i quali opera la politica in questione. Lo scopo principale di questa tesi e quello di acquisire di conoscenza dei meccanismi causali attraverso i quali una politica per lo sviluppo produce un e etto. Utilizzo il contesto delle piccole economie dell'Africa rurale, attraverso i due case study relativi ai progetti della Banca Mondiale (WB) nel campo dello sviluppo economico in Nigeria e in Gambia.

Nella prima parte della tesi si considera un progetto WB della costruzione delle strade e si propone una strategia per la derivazione del marginal treatment effect come un ingrediente della l'interconnessione tra la costruzione delle strade, l'accesso ai mercati locali e il benessere delle famiglie nelle piccole economie rurali. La mia ricerca parte dalla letteratura che crea i ponti tra policy evaluation e approccio strutturale alla Heckman (2010) e fornisce una sua applicazione nel contesto di economia dello sviluppo, dove la classica teoria economica spesso non riesce a spiegare il comportamento degli individui. Dopo aver derivato il marginal treatment e ect dell'accesso al mercato al benessere delle famiglie, costruisco un setting per eseguire una valutazione ex-ante della componente infrastrutturale del programma.

Nella seconda parte della tesi, considero il contesto di The Gambia Driven Development Program per esplorare i mechanismi della formazione endogena delle reti sociali, de nite dalle dimensioni dello scambio economico informale tra le famiglie nei villaggi. Gli scambi che consideriamo sono scambi tra le famiglie in termini di lavoro, credito, terra e mezzi di produzione. L'obiettivo della ricerca e duplice: condurre una ricerca empirica sfruttando i network sovrapposti dello scambio economico, cercando di ottenere una maggiore comprensione del ruolo del programma nella formazione delle reti sociali. L'obiettivo principale e quello di distinguere l'effetto del programma che opera indirettamente sulla probabilita di formare un link, attraverso le modi che delle preferenze individuali verso lo scambio economico.
