If you want to understand the shifting balance of power in the world economy, it helps to know the names Jorge Paulo Lemann, Carlos Brito, and Frederico Curado. Lemann, Brazil’s richest man and the dealmaker behind the $52 billion InBev-Anheuser-Busch merger and the $3.3 billion purchase of Burger King (BKW), has just teamed up with Warren Buffett to acquire yet another major American company, H.J. Heinz (HNZ), for $23 billion. Brito, the Brazilian chief executive officer of Anheuser-Busch InBev (BUD), has launched a $20 billion takeover bid for Mexico’s Grupo Modelo (GPMCY)—the maker of Corona beer—and in the process prompted a U.S. antitrust suit. (AB InBev already sells almost one in five beers in the world.) And Curado, the CEO of Embraer (ERJ), the world’s third-largest commercial planemaker, recently inked a $4 billion deal to supply American Airlines with regional jets.
