"The Handbook on Impact Evaluation serves two broad audiences – researchers new to the evaluation field and policy makers involved in implementing development programs worldwide. We hope this book will offer an up-to-date compendium that serves the needs of both audiences, by presenting a detailed analysis of the quantitative research underlying recent program evaluations and case studies that reflect the hands-on experience and challenges of researchers and program officials in implementing such methods."

"Small businesses significantly contribute to the economic development of a country. From purchasing groceries on an app to enabling new modes of learning, small businesses, especially start-ups, are transforming India into a technology-driven nation. This handbook is an endeavour to provide insight on several models that could be explored to set up a fund to promote start-ups, contributions to which would qualify as CSR spend under the Section 135 of the Companies Act, 2013."

"The vast majority of micro and small enterprises (MSEs) in developing countries are located in industrial clusters, and the majority of such clusters have yet to see their growth take off. The performance of MSE clusters is especially low in Sub-Saharan Africa. While existing studies often attribute the poor performance to factors outside firms, problems within firms are seldom scrutinized. In fact, entrepreneurs in these clusters are unfamiliar with standard business practices. Based on a randomized experiment in Ghana, this study demonstrates that basic-level management training improves business practices and performance."

"Firm productivity is low in African countries, prompting governments to try a number of active policies to improve it. Yet despite the millions of dollars spent on these policies, we are far from a situation where we know whether many of them are yielding the desired payoffs. This paper establishes some basic facts about the number and heterogeneity of firms in different sub-Saharan African countries and discusses their implications for experimental and structural approaches towards trying to estimate firm policy impacts. It shows that the typical firm program such as a matching grant scheme or business training program involves only 100 to 300 firms, which are often very heterogeneous in terms of employment and sales levels. As a result, standard experimental designs will lack any power to detect reasonable sized treatment impacts, while structural models which assume common production technologies and few missing markets will be ill-suited to capture the key constraints firms face. Nevertheless, the author suggests a way forward which involves focusing on a more homogeneous sub-sample of firms and collecting a lot more data on them than is typically collected."

"Corporate venturing has gained much attention due to challenges and changes that occur because of discontinuous innovations - which seem to be promoted by digitalization. In this context, open innovation has become a promising tool for established companies to strengthen their innovation capabilities. While the external opening of the innovation process has gained much attention, the internal opening lacks on investigations. Especially new organizational forms, such as Internal Corporate Accelerators, have not been investigated sufficiently. This study, which is based on 13 interviews from two German tech-companies, contributes to a better understanding of this new form of corporate venturing and the resulting effects on the organizational renewal."

"Over the last six months, Nesta has been working with the Impact Management Project to explore how we think about evidence of impact. This document provides guidance on both using existing evidence of impact, and building your own evidence base."

Written by ANDE's Director of Research and Impact, this article gives an overview of why to measure impact, what to measure, how to collect data, and practical considerations for putting impact data into practice.

"This paper examines the relative importance of the caste system in explaining the resource misallocation in India and quantifies its impact on aggregate productivity. I document that the historically disadvantaged castes (LC) are less likely to enter entrepreneurship even though they are more productive on average. At the intensive margin, the LC entrepreneurs are less capital-intensive but have higher marginal revenue product of capital relative to high castes. In a quantitative model of entrepreneurship, I find that the LC face higher entry cost and stricter financial constraints and that such asymmetries reduce aggregate TFP by 2.54% and output by 6%."

"For the past two years I have been the chair of the research committee of a multi-country survey effort known as the Global Entrepreneurship Monitor (GEM) project, which has begun to make headway in understanding how different types of entrepreneurship affect development. The starting point has been to distinguish “necessity entrepreneurship,” which is having to become an entrepreneur because you have no better option, from “opportunity entrepreneurship,” which is an active choice to start a new enterprise based on the perception that an unexploited or underexploited business opportunity exists. Analyzing data gathered by GEM researchers in 11 countries, Atilla Varga and I have found that effects on economic growth and development of necessity and opportunity entrepreneurship vary greatly. We found that necessity entrepreneurship has no effect on economic development while opportunity entrepreneurship has a positive and significant effect.

"In emerging-market countries, commercial institutions do not always develop sufficiently quickly or effectively to support ambitious entrepreneurs. How might intermediaries remedy these problems? We address this question by drawing on institutional literatures to develop the concept of "open system intermediaries." Our research design involves examining business incubators in emerging markets as a form of open system intermediary. Empirically, we examine the relative emphasis that business incubators in emerging-market countries place on developing markets versus developing specific businesses. The study further examines how private, government, academic, and non- governmental organization sponsorship of incubators influences the mix of services that incubators provide. In sum, this work contributes to our understanding of how, why, and when intermediaries emerge to address institutional failures."
