Public-Private Partnerships: when and how

When are public-private partnerships (PPPs) better than conventional provision and regulated privatization? And should PPP contracts be structured and governed when this is the case?We show that the defining features of a PPP are (i) bundling of construction and operation, (ii) private but temporary ownership of assets and (iii) intertemporal risk sharingwith the public sector.

The economics of infrastructure finance: Public-private partnerships versus public provision

We examine the economics of infrastructure finance, focusing on public provision and public-private partnerships (PPPs). We show that project finance is appropriate for PPP projects, because there are few economies of scope and assets are project specific. Furthermore, we suggest that the higher cost of finance of PPPs is not an argument in favour of

Cost of Moral Hazard and Limited Liability in the Principal-Agent Problem

In this paper we quantify the potential social-welfare loss due to the existence of limited liability in the principal-agent problem. The worst-case welfare loss is defined as the largest possible ratio between the social welfare when the agent chooses the effort that is optimal for the system and that of the sub-game perfect equilibrium of

Structural unemployment and the regulation of product market

I assess the impact of product market regulation on unemployment in a large-firm model of the labor market with search frictions and firm entry and exit. Two regulatory frictions are considered: administrative costs of establishing a new firm and the share of capital entrepreneurs recover when exiting. Product market regulation explains half the unemployment gap

Non-revelation Mechanisms in Many-to-One Markets

This paper presents a sequential admission mechanism where students are allowed to send multiple applications to colleges and colleges sequentially decide the applicants to enroll. The irreversibility of agents decisions and the sequential structure of the enrollments make truthful behavior a dominant strategy for colleges. Due to these features, the mechanism implements the set of

The Effectiveness of Private Voucher Education: Evidence from Structural School Switches

In this paper we analyze the effect of private voucher education on student academic performance using new data on Chilean students and a novel identification strategy. Most schools in Chile provide either primary or secondary education. We analyze the effect of private voucher education on students that are forced to enroll at a different school

Labor force heterogeneity: implications for the relation between aggregate volatility and government size

There is substantial evidence of a negative correlation between government size and output volatility. We put forward the hypothesis that large governments stabilize output fluctuations because in economies with high tax rates the share of total market hours supplied by demographic groups exhibiting a more volatile labor supply is lower.This hypothesis is motivated by the

Renegociación de concesiones en Chile

Este trabajo describe en forma sistemática los montos renegociados en las 50 concesiones cuyos datos han sido publicados por el MOP en su página web. Nuestra principal conclusión es que las renegociaciones son frecuentes y que involucran montos considerables. En promedio, cada concesión ha sido renegociada 3 veces, resultando en transferencias a los concesionarios de

Aggregate Implications of Employer Search and Recruiting Selection

This paper develops a general equilibrium model of nonsequential employer search with recruiting selection and heterogeneous workers, and characterizes its equilibrium. I depart from the standard search model by allowing firms to simultaneously meet several applicants and choose the best candidate. Recruiting selection is important: firms interview a median of 5 applicants per vacancy and

Inflation and welfare in long-run equilibrium with firm dynamics

We analyze the welfare cost of inflation in a model with cash-in-advance constraints and an endogenous distribution of establishments` productivities. Inflation distorts aggregate productivity through firm entry dynamics. The model is calibrated to the United States economy and the long-run equilibrium properties are compared at low and high inflation. We find that, when the period

Wage dispersion and Recruiting Selection

In this paper I introduce a novel source of residual wage dispersion. In the model, workers are heterogenous in productivity and randomly apply to ex ante identical posted vacancies. Each employer simultaneously meets several applicants, offers the position to the best candidate and bargains with her about the wage. Since the outside option of the

Conflict Resolution in the Electricity Sector - The Experts Panel of Chile

One of the main challenges facing the electricity sector worldwide is the design of efficient markets. In particular, the mechanisms used to solve regulatory conflicts are a crucial element of a regulatory regime and a major determinant of the risks borne by private investors. We use the Chilean experience to analyze the evolution of mechanisms
