Imported Inputs , Quality Complementarity , and Skill Demand ∗
This paper analyzes how access to imported inputs affects firms in developing countries, where domestically produced high-quality inputs are relatively costly. We build an O-Ring type model with quality complementarity across input tasks, ranking tasks by their qualitysensitivity. Because high-quality inputs are relatively cheap in international markets, firms use these instead of domestic inpu...
متن کاملSkill Upgrading and Imports in US Manufacturing
The majority of skill-upgrading in the United States in the 1980s and early 1990s was due to within industry shifts in skill-intensity. Traditional trade theory, represented by the HeckscherOhlin model, predicts that trade affects relative employment primarily by shifting resources across industries. For this reason, many economists have concluded that international trade has played a minor rol...
متن کاملSkill Upgrading and Imports in US Manufacturing
Recent theoretical models show that international trade can induce within-industry skillupgrading by raising R&D intensity and creating skill-biased technologies. This paper tests this assertion by estimating the effect of rising import shares on wage shares for 4-digit SIC US manufacturing industries. Using Arellano-Bond estimation to account for the endogeneity of imports, I find that neither...
متن کاملSkill Upgrading and the Real Exchange Rate
This paper examines the effect of changes in the real exchange rate on skill upgrading in the case of Chile. Using plant-level data from the manufacturing sector we find that a real depreciation increases the share of skilled workers in the total wage bill in exporters but not in non-exporters. This result suggests that depreciations or, more generally, increases in export profitability, may in...

While the need for hierarchies within control systems is apparent, it is also clear to many researchers that such hierarchies should be learned. Learning both the structure and the component behaviors is a diicult task. The beneet of learning the hierarchical structures of behaviors is that the decomposition of the control structure into smaller transportable chunks allows previously learned kn...
