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...

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...

This paper proposes some basic elements of a conceptual framework to help organize the thinking about policies that can strengthen the knowledge mission of the World Bank. It first argues that the Bank occupies a unique and prominent subset of the social and economic development"knowledge...

The"conventional wisdom"in academic and policy circles argues that, while large and foreign banks are generally not interested in serving SMEs, small and niche banks have an advantage in doing so because they can overcome SME opaqueness through relationship lending. This paper shows that there...

This paper argues that the dominant policy paradigm on financial development is increasingly insufficient to address big emerging issues that are particularly relevant for financial systems in Latin America. This paradigm was shaped over the past decades by a fundamental shift in thinking toward...
