The Toyota way or Entropy? What did we find when we went back 8-9 years after improving management in Indian factories?

David McKenzie's picture

Between 2008 and 2010, we hired a multinational consulting firm to implement an intensive management intervention in Indian textile weaving plants. Both treatment and control firms received a one-month diagnostic, and then treatment firms received four months of intervention. We found (ungated) that poorly managed firms could have their management substantially improved, and that this improvement resulted in a reduction in quality defects, less excess inventory, and an improvement in productivity.

Should we expect this improvement in management to last? One view is the “Toyota way”, with systems put in place for measuring and monitoring operations and quality launch a continuous cycle of improvement. But an alternative is that of entropy, or a gradual decline back into disorder – one estimate by a prominent consulting firm is that two-thirds of transformation initiatives ultimately fail. In a new working paper, Nick Bloom, Aprajit Mahajan, John Roberts and I examine what happened to the firms in our Indian management experiment over the longer-term.

Behavioral design: slap or tax yourself into productivity?

One of those stories going the rounds about a month ago concerns a blogger in San Francisco, who worried he was wasting too much time on Facebook and Reddit. As he writes on his blog, he used a software app which tracked what he was doing with his time and found almost 19 hours a week went to these activities.

The Impact of Hiring Workers from More Productive Firms- what really cool data tells us

David McKenzie's picture

A number of developed countries now have linked employer-employee records, although to date I haven’t seen as many papers doing cool things with such data as I would expect. A new paper in the AEJ-Applied (ungated here) by Andrey Stoyanov and Nikolay Zubanov uses Danish data to show what is possible, and help provide some of the most convincing evidence yet that workers carry firm knowledge with them when they move.

Sadness interfering with work: depression and labor supply in developing countries

Jed Friedman's picture

If economists view mental health as one component of human capital, as we typically view physical health, then it’s a natural step to the corollary view that good mental health leads to productivity enhancing behaviors such as increased labor supply, greater effort, enhanced concentration, and so on. Given its productive role perhaps mental health, often neglected in the policy realm, deserves more attention. Unfortunately there are precious few studies till date that actually establish such a link between psychological health and productivity.
