A projection of future trends in labor productivity and TFP remains very difficult. The
service-producing sectors are still in a state of disequilibrium following the financial crisis with a negative reported rate of TFP change. It also seems evident that agriculture still accounts for a substantial level of underemployment; so that fast growth in the other sectors will draw workers out of agriculture and contribute to a positive rate of TFP change within agriculture. In future research, it would be useful to disaggregate the service-producing sector to exclude the highly capital intensive sector of homeownership and to focus more directly on the problems of finance. It is also likely that many services industries, such as public administration, display constant labor productivity by assumption.
