This study investigates worker shares of the returns to scale and returns to technology adoption on U.S. hog farms. The wage analysis controls for a matching process by which workers are linked to farms of different sizes and technology uses. Using four surveys of employees on hog farms...

The hypothetical distribution of multiple technology adoptions under the assumption that technologies are mutually independent is compared against the actual observed distribution of technology adoptions on hog farms. Combinations of technologies that occur with greater frequency than would...

A long-standing puzzle in labor economics has been the positive relationship between wages and firm size. Even after controlling for worker's observed characteristics such as education, work experience, gender, and geographic location, a significant firm size wage effect averaging 15 percent...

By allowing agents to switch from entrepreneurship to wage work and vice versa over the life cycle, this study proposes a dynamic Jacks-of-All-Trades (JAT) model where entrepreneurs invest in highly varied skills to manage their business. We simultaneously endogenize human capital investment and...

We propose a strategy to identify the complementarity or substitutability amongtechnology bundles. Under the assumption that alternative technologies are independent,we develop a hypothetical distribution of multiple technology adoptions. Differencesbetween the observed distribution of...

We conducted large-scale lost letter experiments in Beijing, a megacity with more than 21 million residents, to test if the observed altruistic attribute of the letter recipient would induce more passersby to return the lost letters. The treatment letters were addressed to a nationally renowned...

We present findings from an evaluation study of the Dual-Teacher program, a computer- assisted instruction program, that makes lecture videos and other teaching resources from an elite urban middle school available through the internet to schools in poor and remote areas in China. The unique...

We conducted a large-scale lost letter experiment with a novel design across all seasons in Beijing to study whether ambient air pollution influences helping behavior. We assessed air pollution by PM2.5 and PM10. Our novel design allowed us to collect real-time granular data from the streets. To...
