We study the differential impact of large exchange rate devaluations on the cost of living at different points on the income distribution. Across product categories, the poor have relatively high expenditure shares in tradeable products. Within tradeable product categories, the poor consume lower-priced varieties. Changes in the relative price of tradeables and the relative prices of lower-priced varieties following a devaluation will affect the cost of the consumption basket of the low-income households relative that of the high-income households. We quantify these effects following the 1994 Mexican peso devaluation and show that their distributional consequences can be large. In the two years that follow the devaluation, the cost of the consumption basket of those in the bottom decile of the income distribution rose between 1.46 and 1.6 times more than the cost of the consumption basket for the top income decile.
We investigate how multinational firms contribute to the transmission of shocks across countries using a large multicountry firm-level data set that contains cross-border ownership information. We use these data to document two novel empirical patterns. First, foreign affiliate and headquarter sales exhibit strong positive comovement: a 10% growth in the sales of the headquarter is associated with a 2% growth in the sales of the affiliate. Second, shocks to the source country account for a significant fraction of the variation in sales growth at the source-destination level. We propose a parsimonious quantitative model to interpret these findings and to evaluate the role of multinational firms for international business cycle transmission. For the typical country, the impact of foreign shocks transmitted by all foreign multinationals combined is non-negligible, accounting for about 10% of aggregate productivity shocks. On the other hand, since bilateral multinational production shares are small, interdependence between most individual country pairs is minimal. Our results do reveal substantial heterogeneity in the strength of this mechanism, with the most integrated countries significantly more affected by foreign shocks.
The production of capital equipment is concentrated among a small group of countries, and many countries import a large share of their equipment. Given a large body of research arguing that capital-skill complementarity is an important feature of technology, it is possible that international trade has important e¤ects on the skill premium through its impact on the accumulation of capital equipment. In this paper we propose a tractable framework for evaluating this e¤ect and provide simple analytic expressions linking observable changes in import shares by sector to changes in the real wages of skilled and unskilled workers and, therefore, the skill premium. Quantitatively, we …nd that while international trade raises the real wages of both skilled and unskilled workers, it bene…ts skilled workers disproportionately, especially in countries that rely heavily on imports for their capital equipment.
