“…Recent contributions on the informal economy also include: Sarte (2000), who studies the e ect of informality on growth in the presence of rent-seeking bureaucrats; Azuma and Grossman (2002), who show how the Government, in the presence of unobservable endowments, can extract from producers such a high amount to force the poorly endowed in the informal sector; Dessy and Pallage (2003), who propose a model with strategic complementarities where legal rms pay taxes that nance the provision of a productivity enhancing good; Fugazza and Jacques (2003), who develop a matching model of the labor market with formal and informal workers, showing that policies which encourage the participation in the legal sector are more e ective than deterrence; Busato and Chiarini (2004), who develop a business cycle model with a legal and an informal sector to stress the risk sharing opportunities allowed by the reallocation of labor supply across sectors; Maloney (2004), who studies the informal sector empirically in Latin America highlighting its entrepreneurial nature; Gerxhani (2004), who compares the informal sectors in developed and less developed countries; Choi and Thum (2005), who show how the option for an entrepreneur to produce illegally reduces the rents that corrupt public o cials can extract; Amaral and Quintin (2006), who show that informal rms substitute low-skilled labor for physical capital because of nancial constraints; Dabla-Norris, Gradstein and Inchauste (2008), who show, empirically, that the quality of the legal system is an important determinant of informality; De Paula and Scheinkman (2008), who build equilibrium models of informality and test them on a survey of Brazilian rms, showing that informality spreads along the supply chain in the presence of VAT collected with the credit system; La Porta and Shleifer (2008), who show, with survey data, that informal rms are ine cient, less capitalized and worse managed than legal rms; Blackburn, Bose and Capasso (2012), who highlight the trade-o between evading taxes and o ering collateral for investments, which means that the incentive to evade taxes is higher in less nancially developed countries; Capasso and Jappelli (2013), who also show, empirically, a negative relationship between nancial development and tax evasion as a consequence of the trade-o between tax evasion and the necessity to have collateral for investments; Ordonez (2014), who builds a general equilibrium model to show how incomplete tax enforcement decreases aggregate productivity and output.…”
