A Bird in the Hand is Worth Two in the Bush: Technology Search Strategies and Competition Due to Import Penetration

Do firms respond to tougher competition by searching for completely new technological solutions (exploration), or do they work to defend their position by improving current technologies (exploitation)? Considering the different times to fruition for exploration versus exploitation, in the presence of heightened competition, we argue that firms might not be able to wait for the benefits of technological exploration to materialize. With a panel data set of U.S. manufacturing firms, we show that tougher competition, due to import penetration, leads to a decrease in technological exploration and an increase in technological exploitation. These effects are heterogeneous across industries, firms, and time. To obtain exogenous variation in competition we rely on both instrumental variable regressions and a difference-in-differences design exploiting large changes in import tariffs.
