The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

Distributional consequences typically receive limited attention in economic models that analyze the effects of monetary and financial sector policies. These consequences deserve more attention since financial markets are incomplete, imperfect, and economic agents' access to them is often...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained...

We develop a two-sector, heterogeneous-agent model with incomplete financial markets to study the distributional effects and aggregate welfare implications of alternative monetary policy rules in emerging market economies. Relative to inflation targeting, exchange rate management benefits...

In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

Very little is known about the effectiveness of SME policies, and a careful look at the structure, mechanisms and incentives provided by these policies suggest caution in their implementation and, most importantly, the need to carefully and closely monitor their results. This paper relies on the...

The guide outlines the main evaluation challenges associated with ALMP s, and shows how to obtain rigorous impact estimates using two leading evaluation approaches. The most credible and straightforward evaluation method is a randomized design, in which a group of potential participants is...

Although many countries are aggressively implementing the One Laptop per Child (OLPC) program, there is a lack of empirical evidence on its effects. This paper presents the impact of the first large-scale randomized evaluation of the OLPC program, using data collected after 15 months of...
