We build a model of firms' choice between formality and informality. Complying with costly registration procedures allows the firms to benefit from key public goods, enforcement of property rights and contracts, that make the participation in the formal credit market possible. In a moral hazard framework with credit rationing, their decision is shaped by the interaction between the cost of entry into formality, and the relative efficiency of formal versus informal credit mechanisms and their related institutional arrangements. The model is consistent with existing stylized facts on the determinants of informality. D
High rates of contract renegotiation have raised serious questions about the viability of the concession model to attract private participation in infrastructure in developing countries. After extending in reduced form a standard regulation model, in which renegotiation occurs due to the imperfect enforcement of concession contracts, we use a unique data set of 307 concessions awarded in Latin America from 1989 to 2000, covering the sectors of transport and water, to analyze the determinants of this high incidence of renegotiations of infrastructure contracts. We look in details at the impact, on the probability of renegotiation of a concession, of regulatory institutions, institutional features, economic shocks and of the characteristics of the concession contracts themselves. We then derive some policy implications of our work.
SUMMARYThis paper analyzes government-led renegotiations in infrastructure concession contracts in Latin America, based on the same sample used in Guasch, Laffont and Straub (2003) to examine firm-led renegotiations. After extending the theoretical framework to a multiple-period context in which both Pareto-improving and rent-shifting renegotiations at the initiative of the government can occur, we develop an original instrumental variable strategy to address the issue of contract endogeneity and derive empirical results. While some of the main insights concerning the importance of having a regulator in place when awarding concessions and the fragility of price cap regulatory schemes are unchanged, significant differences arise with respect to the effect of investment and financing, as well as the corruption variables. We provide evidence that a good regulatory framework is especially important in contexts with weak governance and political opportunism.
The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors. They do not necessarily represent the views of the International Bank for Reconstruction and Development/World Bank and its affiliated organizations, or those of the Executive Directors of the World Bank or the governments they represent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
