We assess the empirical validity of the trilemma (or impossible trinity) in the 2000s for a large sample of advanced and emerging market economies. To do so, we estimate Taylor-rule type monetary policy reaction functions, relating the local policy rate to real-time forecasts of domestic fundamentals, global variables, as well as the base-country policy rate. In the regressions, we explore variations in the sensitivity of local to base-country policy rates across different degrees of exchange rate flexibility and capital controls. We find that the data are in general consistent with the ...

Case studies and econometric evidence demonstrate that IT has enabled firms to more rapidly replicate improved business processes throughout an organization, thereby not only increasing productivity but also market share and market value. We develop a simple model that shows how IT-enabled business ...
