aOur preceding discussion indicates that macroeconomic changes provide an exogenous source of variation that allows researchers to examine the effect of leverage on competition. An alternative way to examine these issues is to examine how firms respond to exogenous shocks to their competitive environments...
Electroplating is a technique in which a thin layer of metal is deposited, using an electric current, onto an object to enhance the surface characteristics.
An A unit is a railwaylocomotiveused as the manned master unit in multiple locomotive train configurations. When trains are configured to be driven by multiple locomotive units, only one unit has a driver; all control inputs are remotely relayed to the others. These control relays generally take...
