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.

Carson, R., Graff Zivin, J.S., Louviere, J., Sadoff, S., Shrader Jr, J.G.

This experiment tries to understand how managers respond to uncertainty when making research and development decisions. Three experiments were conducted with master’s degree students in a program focused on the intersection of business and technology.

Dimitriadis, S., Koning, R.

What is preventing entrepreneurs and managers from forming peer connections themselves? This paper argues that entrepreneurs may be under-networked because they lack the necessary social skills that allow them to match efficiently with knowledgeable peers.

Shane, S., Clingingsmith D., Drover W., and Cerf M.

We explore how variation in entrepreneurs' displayed passion affects informal investor interest in start-up ventures by examining neural responses to entrepreneurs' pitches using functional Magnetic Resonance Imaging (fMRI). We find that founders displaying high passion increase investor neural engagement by 39% and investor interest in the venture by 26% over those displaying low passion. A one standard deviation increase in neural engagement is associated with an 8% percent increase in investors' interest in investing in a start-up company relative to the mean.

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.

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.

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.

Meager, R.

In this paper, meager jointly estimates the average effect and the heterogeneity in effects across seven studies using Bayesian hierarchical models.

de Mel, S., McKenzie, D., Woodruff, C.

A field experiment in Sri Lanka provided wage subsidies to randomly chosen microenterprises to test whether hiring additional labor benefits such firms, and whether a short-term subsidy can have a lasting impact on firm employment. Using 12 rounds of surveys to track dynamics four years after treatment, we find that firms increased employment during the subsidy period. Treated firms were more likely to survive, but there was no lasting impact on employment, and no effect on profitability or sales either during or after the subsidy period.

While prior research shows a significant gender gap in traditional equity financing, with mostly male investors who prefer male founders, emerging evidence indicates that gender gaps in funding may not translate to rewards-based crowdfunding, where female entrepreneurs may have an advantage, particularly with female investors. We seek to examine founder gender preferences in the context of equity crowdfunding, which represents a direct counterpart to traditional equity financing and which is a “higher-stakes” context than rewards-based crowdfunding.

Increasing evidence indicates the importance of management in determining firms’ productivity. Yet, causal evidence regarding the effectiveness of management practices is scarce, especially for high-skilled workers in the developed world. In an eight-month field experiment measuring the productivity of captains in the commercial aviation sector, we test four distinct management practices: (i) performance monitoring; (ii) performance feedback; (iii) target setting; and (iv) pro-social incentives.

Lee, D., Dizon-Ross, R., Krieger, J., Fehder, D., Hochberg, Y.

Lack of secular economic opportunity is believed to be related to social unrest, engagement in terrorism, and association with radical groups. In conflict areas, difficulties accessing economic opportunity and employment are often exacerbated by movement restrictions and investor concerns about safety of physical plant and other capital investments that might enhance employment opportunities. Recent advances in cloud-computing and software-driven services present the promise of a solution through cloud-based entrepreneurial activity.
