Some firms say they care about the well-being and “happiness” of their employees. But are such claims hype or scientific good sense? We provide evidence, for a classic piece rate setting, that happiness makes people more productive. In three different styles of experiment, randomly selected individuals are made happier. The treated individuals have approximately 12% greater productivity. A fourth experiment studies major real-world shocks ðbereavement and family illnessÞ. Lower happiness is systematically associated with lower productivity.

We investigate the relationship between employees' and managers' training and firm performance using a policy intervention that randomly assigned training support to small‐ and medium‐sized enterprises in the UK accommodation and food service sector. Because the number of firms self‐selected into training exceeded available places, training was randomly assigned to some firms, resulting in a randomized natural experimental design that allowed us to identify the average effect of training on treated firms.

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.

Entrepreneurship programmes have a strong positive effect on youths, particularly on labour-market activities and business-practice outcomes, and improve business knowledge and practice, particularly for existing entrepreneurs. However, there is no evidence that this translates into improved business performance and increased income.

Most academic and development policy discussions about microentrepreneurs focus on credit constraints and assume that subject to those constraints, the entrepreneurs manage their business optimally. Yet the self-employed poor rarely have any formal training in business skills. A growing number of microfinance organizations are attempting to build the human capital of microentrepreneurs in order to improve the livelihood of their clients and help further their mission of poverty alleviation.
