Meta-analýza v mezinárodní ekonomii

Havránek, Tomáš

The dissertation consists of three papers presenting applications of meta-analysis in international economics. The first paper examines the effect of common currency on international trade, while the remaining two papers address the relationship between foreign investment and the productivity of domestic firms. An introductory chapter puts these applications into perspective. In the first application I present a meta-analysis of the effect of currency unions on trade, focusing on the euro area. I find strong publication bias in the literature. The estimated trade- promoting effect of currency unions other than the euro reaches more than 60%. In contrast, the euro's trade-promoting effect is insignificant when I correct for publication bias. The empirical literature on this topic shows signs of the so-called economics research cycle: the relation between the reported t-statistics and publication years has an inverse U-shaped form. During the last decade more than 100 researchers have examined productivity spillovers from foreign affiliates to local firms in upstream or downstream sectors. Yet results vary broadly across methods and countries. To examine these vertical spillovers in a systematic way, in the second application I collect 3,626 estimates of spillovers and review the literature quantitatively....
