This paper evaluates the global welfare impact of observed levels of migration using a quantitative multi-sector model of the world economy calibrated to aggregate and firm-level data. Our framework features cross-country labor productivity difference, international trade, remittances, and a...

This paper provides a forensic account of the role of individual firms in generating aggregate fluctuations using data covering the universe of French firms for the period 1990–2007. We derive a theoretically-founded set of estimating equations that decompose firms’ annual sales growth rate...

This paper evaluates the global welfare impact of China's trade integration and technological change in a multi-country quantitative Ricardian-Heckscher-Ohlin model. We simulate two alternative growth scenarios: a "balanced" one in which China's productivity grows at the same rate in each...

This paper shows that an income effect can drive expenditure switching between domestic and foreign goods. We use a unique Latvian scanner-level dataset for food and beverages, covering the 2008-09 financial crisis, to study (i) relative price movements, and (ii) expenditure switching between...

Existing estimates of power laws in firm size typically ignore the impact of international trade. Using a simple theoretical framework, we show that international trade systematically affects the distribution of firm size: the power law exponent among exporting firms should be strictly lower in...

This paper analyses the extent to which ASEAN may be suitable for a regional monetary arrangement. On the economic front, we review evidence on patterns of trade, economic shocks, the extent of factor mobility, and the monetary transmission mechanism. We find that ASEAN today is less suitable...

We identify the groups of countries where international risk-sharing opportunities are most attractive. We show that the bulk of risk-sharing gains can be achieved in groups consisting of as few as seven members, and that further marginal benefits quickly become negligible. For many such small...

This paper examines the relationship between fiscal policy and the current account, drawing on a larger country sample than in previous studies and using panel regressions, vector auto-regressions, and an analysis of large fiscal and external adjustments. On average, a strengthening in the...

Drawing on a newly-collected data set on bond yields, macroeconomic variables, and news of various categories for a panel of emerging markets, we provide the first comparative analysis of the determinants of sovereign bond spreads in the first era of financial globalization and bond finance...

This paper analyzes the interactions between business and financial cycles using an extensive database of over 200 business and 700 financial cycles in 44 countries for the period 1960:1-2007:4. Our results suggest that there are strong linkages between different phases of business and financial...
