The empirics of microfinance: what do we know?

Microfinance has received a lot of attention recently, both from policy makers as well as in academic circles. Two of the main topics that have been hotly debated are explaining joint liability group lending and its implications for reducing information asymmetries, and the trade-off between the financial sustainability and outreach of microfinance programmes. This Feature contains three novel empirical contributions providing new insights with respect to why and how joint liability group lending works. It also contains the first large-scale systematic analysis of the trade-off between financial performance and outreach of microfinance institutions.

Public debt and economic growth: what do neoclassical growth models teach us?

This paper aims to quantify the crowding-out effect of public debt and the related loss in long-run output in neoclassical growth models. To accomplish this task, we incorporate the government sector into the Ramsey–Cass–Koopmans (RCK) model, the Blanchard model and the Solow model, which differ only in their assumptions concerning the consumption behaviour of households. We also introduce a general framework that is capable of gauging the burden of public debt in a neoclassical world in the case of any type of consumption behaviour. Our results are threefold. First, contrary to the RCK model, public debt reduces long-run output in the Blanchard model and the Solow model, although to a different extent: the crowding-out effect is marginal in the former, whereas it can be very large in the latter. Second, the burden of public debt is country-specific depending crucially on the saving rate and the population growth rate. Finally, in developed countries the upper limit of the output loss related to public debt is moderate at best even if distortionary taxes are taken into account.     

Learning to do: Facilitating practice in a large introductory macroeconomics class

Contemporary pedagogy encourages instructors to move away from memorization to teaching the ability to “do economics.” In such an environment, students are taught to apply knowledge of economic measurement, the economic model, and economic policy to analyze current events and policies. In this article, the authors build on existing literature describing independent activities by sharing a set of class exercises and assignments that comprise an entire course. The course discussed in this article is a large enrollment introductory course and presents a novel approach to active learning, adapted to this often-challenging context. The course emphasizes engaging students by encouraging them to practice using macroeconomic tools.

For they know not what they do: an analysis of monetary policy during the Great Moderation

In this article, we develop an empirical framework to show the importance of money during the Great Moderation, while accounting for the fact that monetary policy was exclusively conducted through interest rates. We estimate the impulse response functions and forecast error variance decomposition derived from a structural VAR with a least absolute shrinkage and selection operator–based lag selection. The variance decomposition suggests that a substantial component of macroeconomic variation has been driven by shocks to the money market, which were not only unintended by the Federal Reserve, but worse passed unnoticed allowing those shocks to accumulate over time.
