Latin America's historically low saving rates and sub-par growth performance raise the question of whether the region should save more to grow faster. Economists generally resist acknowledging a policy-exploitable causal connection going from saving to growth because domestic saving is perceived...

This paper examines the conceptual foundations of macroprudential policy by reviewing the literature on financial frictions from a policy perspective that systematically links state interventions to market failures. The method consists in gradually incorporating into the Arrow-Debreu world a...

This paper explores the conceptual foundations of macroprudential policy. It does so within a framework that gradually incorporates and interacts two types of frictions (principal-agent and collective action) with two forms of rationality (full and bounded), all in the context of aggregate...

The Subprime crisis largely resulted from failures to internalize systemic risk evenly across financial intermediaries and recognize the implications of Knightian uncertainty and mood swings. A successful reform of prudential regulation will need to integrate more harmoniously the three...

This paper analyzes the bright and dark sides of the financial development process through the lenses of the four fundamental frictions to which agents are exposed -- information asymmetry, enforcement, collective action, and collective cognition. Financial development is shaped by the efforts...

The global financial crisis brought public guarantees to the forefront of the policy debate. Based on a review of the theoretical foundations of public guarantees, this paper concludes that the commonly used justifications for public guarantees based solely on agency frictions (such as adverse...

Financial crises can happen for a variety of reasons: (a) nobody really understands what is going on (the collective cognition paradigm); (b) some understand better than others and take advantage of their knowledge (the asymmetric information paradigm); (c) everybody understands, but crises are...

A widely shared view holds that there is no policy-exploitable causal connection from saving to growth because domestic saving is fully endogenous, optimally determined, or substitutable by foreign saving. Yet, abandoning these assumptions, which are questionable in the real world of frictions,...
