"A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen...

This paper uses new data to study school management and productivity in India. We report four main results. First, management quality in public schools is low, and ~2σ below high-income countries with comparable data. Second, private schools have higher management quality, driven by much...

A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen...

Beginning in 2008, we ran a randomized controlled trial that changed management practices in a set of Indian weaving firms (Bloom et al. 2013). In 2017 we revisited the plants and found three main results. First, while about half of the management practices adopted in the original experimental...

We collect data on operations, targets and human resources management practices in over 1,800 schools educating 15-year-olds in eight countries. Overall, we show that higher management quality is strongly associated with better educational outcomes. The UK, Sweden, Canada and the US obtain the...

We explore how firms grow by adding products. In contrast to most earlier work on the topic, our conceptual and empirical framework allows for separate treatment of product innovation (vertical differentiation) and diversification (horizontal differentiation). The market context is Japan's...

Between 1800 and 1860, the United States became the preeminent world supplier of cotton as output increased sixty-fold. Technological changes, including the introduction of improved cotton varieties, contributed significantly to this growth. Measured output per worker in the cotton sector rose...

The Cliometrics literature on slave efficiency has generally focused on static questions. We take a decidedly more dynamic approach. Drawing on the records of 142 plantations with 509 crops years, we show that the average daily cotton picking rate increased about four-fold between 1801 and 1862....

During the first half of of the nineteenth century the United States emerged as a major producer of cotton textiles. This paper argues that the expansion of domestic textile production is best understood as a path- dependent process that was initiated by the proetction provided by the Embargo...

Recent research has suggested that the antebellum U.S. cotton textile industry would have been wiped out had it not received tariff protection. We reaffirm Taussig's judgment that the U.S. cotton textile industry was largely independent of the tariff by the 1830s. American and British producers...
