Do capital grants improve microenterprise productivity? We use the lens of a production function to re-examine two previous randomised controlled trials that allocated capital to microenterprises. We find that productivity is higher for treated firms, and accounts for about 20-30 percent of the revenue effects of capital grants. Although long-run estimates are noisy, point estimates indicate that these productivity effects are sustained six years after the grants.

Jin, Y., Sun, Z.

Expansion of e-commerce presents new opportunities for small and medium enterprises (SMEs) to enter broader market at lower costs, but the SMEs face barriers to growth after entry. To facilitate new entrants to overcome these barriers, this paper explores implementing a training program as a randomized controlled experiment with over two million new sellers on a large e-commerce platform.

Cavendish Enterprise's Business Boost trial project involved providing young small firms - typically micro-businesses - with a treatment involving a series of workshops designed to enhance productivity. This was provided largely as a top-up to an advice and mentoring programme called 'Start and Grow'. The project was part of the government's Business Basics Programme which has the core aim of identifying cost effective, yet productivity enhancing, programmes of business support for SMEs which can be run at scale throughout the country.

Bapna, S., Ganco, M., and Qiu, L.

User entrepreneurs are responsible for the most important innovations in many industries, but little research has explored the performance of firms founded by user entrepreneurs. While user entrepreneurs have a deep knowledge of customer needs that facilitates the identification of innovative solutions, they tend to lack the relevant business knowledge (e.g., market, production, operational and organizational) to successfully exploit opportunities and grow their ventures.

Muehlfeld, K., Rigtering, C., Weitzel, U.

Individual-level opportunity recognition processes are vital to corporate entrepreneurship. However, little is known regarding how managerial communication impacts the effectiveness of idea suggestion systems in stimulating individuals' participation in intrapreneurial ideation. Integrating self-determination theory, creativity, and framing research, we theorize how different ways of inviting employees to submit proposals (opt-out/opt-in registration; provision of examples) affect the number and quality of submitted ideas.

Bouguen, A., Frölich, M., Hörner, D., Wollni, M.

In this study we assess the effects of a decentralized extension program and an additional video intervention on the adoption of integrated soil fertility management (ISFM) among 2,382 farmers in Ethiopia using a randomized controlled trial. ISFM should enhance soil fertility and productivity by combining organic and inorganic soil amendments. We find that both extension-only and extension combined with video increase ISFM adoption and knowledge.

2019
Custodio, C., Merges, D., Metzger, D.

This paper studies the impact of a financial education program for top managers of medium and large enterprises in Mozambique through a randomized controlled trial (RCT). We use survey data and financial reporting data to show consistent evidence that managers adjust some financial policies in response to the education program. The largest treatment effects are on short-term financial policies related to working capital, generating a positive impact on cash flows due to reductions in account receivables and inventories.

Gambardella, A., Camuffo, A., Cordova, A.

A classical approach to collecting and elaborating information to make entrepreneurial decisions combines search heuristics such as trial and error, effectuation, and confirmatory search. This paper develops a framework for exploring the implications of a more scientific approach to entrepreneurial decision making. The panel sample of our randomized control trial includes 116 Italian startups and 16 data points over a period of about one year.
