1. Introduction. Concrete is the most widely used construction material, of which aggregate accounts for about 70%–80% of the volume [[1], [2], [3]].The global annual consumption of concrete is nearly 17.5 billion tons, and that of aggregate is over 13 billion tons [4].At present, the mining of natural aggregate (NA) has caused enormous …

We find that if Indonesia was cut off from MP, aggregate manufacturing productivity would fall by 19.6 percent. Likewise, if Indonesia was not able to trade with neighboring countries we would find an 8.5 percent decline in aggregate manufacturing productivity. These experiments emphasize that firm-level trade and MP interactions are …

We also discussed the aggregation procedures used to establish the aggregate picture for the benchmark years. In this chapter we see how these benchmark estimates can be combined with time series evidence to build up a consistent picture of comparative productivity over time at the level of aggregate manufacturing.
