In light of growing discourse on 'frugal innovation', this book offers novel approaches to innovation based on extensive empirical research. The study complements a decade of scholarly attention on frugal innovation by taking a research-based approach to innovation in resource-scarce and complex...

Networks contain complex patterns of dependency and require multiple levels of analysis to explain their formation, structure, and outcomes. In this Element, the authors develop the Multilevel Network Framework. The framework serves as (i) a conceptual tool to think more deeply about network...

Why are some subnational governments more likely to lobby the national government than others? Extant research in social sciences has widely discussed lobbying dynamics in the private sector. However, governments lobby governments, too. In the United States, lobbying is a popular strategy for...

What is the nonprofit sector and why does it exist? Collecting the writing of some of the most creative minds in the field of nonprofit studies, this book challenges our traditional understanding of the role and purpose of the nonprofit sector. It reflects on the ways in which new cultural and...

This paper critically reviews both mainstream and Keynesian empirical studies of interest rate dynamics. It assesses the key findings of a selected number of these studies, surveying the debates between the mainstream and the Keynesian schools. It also explores the debates on interest rate...

We study how the output gap affects potential output over time-i.e., the dynamic hysteresis effect. To do so, we introduce novel unobserved components (UC) models that consider hysteresis as a sequence of lagged effects, thus separating the long-run recession-induced adverse effects from other...

This paper presents empirical evidence on the nature of idiosyncratic shocks to firms and discusses its role for firm behavior and aggregate fluctuations. We document that firm-level sales and productivity are hit by heavy-tailed shocks and follow a nonlinear stochastic process, thus departing...

We study international monetary policy spillovers and spillbacks in a tractable two-country Heterogeneous Agent New Keynesian model. Relative to Representative Agent (RANK) models, our framework introduces a precautionary-savings channel, as households in both countries face uninsurable income...

We propose an approach for Bayesian inference in time-varying structural vector autoregressions (SVARs) identified with sign restrictions. The linchpin of our approach is a class of rotation-invariant time-varying SVARs in which the prior and posterior densities of any sequence of structural...

Protests and fiscal crises often coincide, with complex causal dynamics at play. We examine the interaction between tax revolts and sovereign risk using a quantitative structural model calibrated to Argentina during the Macri administration (2015-2019). In the model, the government can be...
