This note accompanies the Cross?country Historical Adoption of Technology (CHAT) dataset. CHAT is an unbalanced panel dataset with information on the adoption of over 100 technologies in more than 150 countries since 1800. The data is available for download at: http://www.nber.org/data/chat. We...

We assemble a dataset on technology adoption in 1000 BC, 0 AD, and 1500 AD for the predecessors to today's nation states. We find that this very old history of technology adoption is surprisingly significant for today's national development outcomes. Our strong and robust results are for 1500 AD...

We build a two country asymmetric DSGE model with two features: (i) endogenous and slow diffusion of technologies from the developed to the developing country, and (ii) adjustment costs to investment flows. We calibrate the model to match the Mexico-U.S. trade and FDI flows. The model is able to...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

We develop a new survey instrument to codify CEOs' diaries in large samples and use it to measure the labor supply of 1,114 family and professional CEOs of manufacturing firms across six countries (Brazil, France, Germany, India, the United Kingdom and the United States). By this measure, family...

Over the past years, forward-looking CEOs have adopted a higher-ambition approach to strategy and leadership. These "higher-ambition CEOs" are driven by a sense of purpose that goes beyond achieving financial success. They aspire to build organizations that succeed in the marketplace by earning...

The relatively new concept of a "multi-front negotiation campaign" (Sebenius 2010, Lax and Sebenius, 2012) offers an analytic approach that may...

Platform owners sometimes enter complementors' product spaces to compete against them directly. Prior studies have offered two possible explanations for such entries: platform owners may target the most successful complementors so as to appropriate value from their innovations, or they may...

Roughly 20% of adults in the OECD lack basic numeracy and literacy skills. In the UK, many colleges offer fully government subsidized adult education programs to improve these skills. Constructing a unique dataset consisting of weekly attendance records for 1179 students, we find that...
