What I meant is in countries like Bangladesh who are suffering from acute power shortages the question of whether electricity causes growth or growth leads to higher demand for electricity is not quite pertinent. That electricity is a binding constraint on growth is self evident in these countries. Authorities have stopped allowing new electricity connections to factories and homes; limited hours when shops can remain open; diverted gas from fertilizer production to power generation and so on. If these do not suffice as conclusive evidence that shortage of electricity is indeed choking growth, what will? In our eagerness to produce technically sophisticated evidence, we sometimes lose sight of common sense. Hope this answers your query. Thanks for commenting.
