Their results point to several basic messages. First by imposing enough structure on the production function and rhe demand system it is possible to measure product quality and marginal costs at the plant level and to relate the evolution of these variables to firms activity histories. Doing so. the authors find strong firm-level persistence in both quality and marginal costs. But in most industry or country panels that they study past international activities help little in predicting current performance once past realizations on quality and marginal cost are controlled for. That is activities do not typically Granger-cause performance. Interestingly in the minority of cases where significant associations emerge international activities appear to move costs and product quality in the same direction. So the net effect on profits in these cases is not immediately apparent. Second several basic patterns emerge with respect to the .
