Climate change poses an urgent and existential threat to the wine sector. However, it is not easy for wineries and farmers to take action to reduce carbon emission comparing to adaptation. How can we encourage these actions? Farmers often seek information before take action, which influences their current risk perceptions of extreme weather condition or moral norms. Regarding the information, a positive approach focusing on empowering farmers to take action to address climate change is generally more successful at engaging people and minimizing defensive reactions.

This paper tests whether providing more information on business practices can lead firms to seek out advice and improve their practices. The authors collaborated with a business advice provider in Brazil to implement a randomized experiment with 866 small firms. The treatment groups received different versions of an information sheet that benchmarked business practices to other firms and listed five practices to improve.
The study investigates the role of information constraints and behavioral biases in the under-adoption of key business practices by micro-enterprises in Brazil. We combine a randomized control trial with online surveys to study these questions.
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.
This study analyses a field experiment conducted on AngelList Talent, a large online search platform for startup jobs.
We examine the influence of physical proximity on between-startup knowledge spillovers at one of the largest technology co-working hubs in the United States. Relying on the random assignment of office space to the hub's 251 startups, we find that proximity positively influences knowledge spillovers as proxied by the likelihood of adopting an upstream web technology already used by a peer startup.
This study asks why more small firms in developing countries do not use the market for professional business services like accounting, marketing, and human resource specialists and asks how this could be altered.
This randomised experiment tested the impact of exogenously inducing higher financial aspirations among poor entrepreneurs.
Using survey and register data, this experiment estimates the effects of the information treatment brochure on awareness of WeGebAU, on take-up of WeGebAU and other training, and on subsequent employment.
This paper explores what might motivate employees to participate in internal crowdsourcing, a peer-based approach to innovation.
This paper compares how two common incentive schemes affect innovative performance in a field experiment run in partnership with a large life sciences company.
This trial investigates whether excessively optimistic beliefs may play a role in the persistent demand for doctoral and post-doctoral training in science.
We investigate how knowledge similarity between two individuals is systematically related to the likelihood that a serendipitous encounter results in knowledge production. We conduct a field experiment at a medical research symposium, where we exogenously varied opportunities for face-to-face encounters among 15,817 scientist-pairs. Our data include direct observations of interaction patterns collected using sociometric badges, and detailed, longitudinal data of the scientists' postsymposium publication records over 6 years.
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.
This study explores how individuals develop habitual perspectives from repetitive tasks they enact over time, and how these deeply ingrained habits of perspective influence creativity. Further, this study proposes that habits of perspective are resistant to the creativity-stunting effect of financial incentives.
This project aims to understand how increased access to competitor information enabled by digitization affects the strategic decisions and performance of firms.
Examines a program in Benin that drastically reduces costs to formalize a business, while also offering tax mediation and training. Results forthcoming.
This natural field experiment tests the effects of purely symbolic awards on volunteer retention in a public goods context. The experiment is conducted at Wikipedia, which faces declining editor retention rates, particularly among newcomers. Randomization assures that award receipt is orthogonal to previous performance. The analysis reveals that awards have a sizeable effect on newcomer retention, which persists over the four quarters following the initial intervention.
We conducted a field experiment to identify the causal effects of extrinsic incentive cues on the sorting and performance of nascent social entrepreneurs. The experiment, carried out with one of the United Kingdom’s largest support agencies for social entrepreneurs, encouraged 431 nascent social entrepreneurs to submit a full application for a grant competition that provides cash and in-kind mentorship support through a onetime mailing sent by the agency.
By randomising the information sent to potential investors on AngelList over e-mail, this experiment finds evidence that the founding team of a startup has strong influence over the investor's decision to invest.
Examines the effectiveness of a specific management production routine relying on knowledge transfer of managers in a Bangladeshi garment factory. Results forthcoming.
Workers who sort into institutional settings they prefer may work twice (or many more times) as hard in these preferred settings. This productivity effect is especially important in institutional settings where a taste for competition is strongest.
Self-control problems change the logic of agency theory by partly aligning the interests of the firm and worker: both now value contracts that elicit future effort. Findings from a year-long field experiment with full-time data entry workers support this idea. First, workers increase output by voluntarily choosing dominated contracts (which penalize low output but give no additional rewards for high output). Second, effort increases closer to (randomly assigned) paydays.
This paper explores the effectiveness of goal setting and accountability within group-based entrepreneurship initiatives in creating human capital. The study uses a randomized cluster trial to compare the experimental and control groups of entrepreneurs. The results suggest that frequent goal setting and accountability in group settings provides a greater number of learning experiences and human capital development opportunities available to entrepreneurs than those that did not engage in the same level of goal setting.
Micro-entrepreneurs often lack the financial literacy required to make important financial decisions. We conducted a randomized evaluation with a bank in the Dominican Republic to compare the impact of two distinct programs: standard accounting training versus a simplified, rule-of-thumb training that taught basic financial heuristics. The rule-of-thumb training significantly improved firms' financial practices, objective reporting quality, and revenues.
Using the historical random assignment of MBA students to sections at Harvard Business School (HBS), I explore how executive peer networks can affect managerial decision making. Within an HBS class, firm outcomes are significantly more similar among graduates from the same section than among graduates from different sections, with the strongest effects in executive compensation and acquisitions strategy. I demonstrate the role of ongoing social interactions by showing that peer effects are more than twice as strong in the year following staggered alumni reunions.
In the context of consumer lending in South Africa, advertising content has significant effects on demand, even relative to price effects. However, it was very difficult to predict the effects of different advertising content, and highlights the psychological premise that context matters.
In the context of a call centre, behavioural heterogeneity observed through employees shirking when reduced monitoring is introduced has important implications for the design and management of reward systems. Management needs to balance monitoring strategies needed to regulate opportunistic employees with strategies needed to sustain the motivation of the substantial fraction of employees disinclined to shirk.
