How firms react to a given shock may depend on the degree to which rivals are present and on whether potentially viable entrants to that market exist. The authors try to measure these effects internationally by examining the price behavior of the United States in Brazil's market when MERCOSUR...

The welfare effects of preferential trading agreements, are most directly linked to changes in trade prices - that is, the terms of trade.

Even though time series estimates can provide...

Knowledge accumulation means either new knowledge (an increase in its quality), greater access to existing knowledge (an increase in its quantity), or both. The authors examine the relative contribution of these two components of knowledge to total factor productivity (TFP) for North-North and...
