The Global Decline of the Labor Share

Abstract: The stability of the labor share of income is a key foundation in macroeconomic models. We document, however, that the global labor share has signicantly declined since the early 1980s, with the decline occurring within the large majority of countries and industries. We show that the decrease in the relative price of investment goods, often attributed to advances in information technology and the computer age, induced rms

Trade and the Global Recession

Abstract: We develop a dynamic multi-country general equilibrium model to investigate forces acting on the global economy during the Great Recession and ensuing recovery. Our multi-sector framework accounts completely for countries' trade, investment, production, and GDPs in terms of different sets of shocks. Applying the model to 21 countries, we investigate the 29 percent drop in world trade in manufactures during 2008-2009. A shift in final spending away from tradable sectors, largely caused by declines in durables investment efficiency, account for most of the collapse in trade relative to GDP. Shocks to trade frictions, productivity, and demand play minor roles.

Trade Adjustment and Productivity in Large Crises

Abstract: The authors empirically characterize the mechanics of trade adjustment during the Argentine crisis using detailed firm-level customs data covering the universe of import transactions made during 1996-2008. Their main findings are as follows: First, the extensive margin defined as the entry and exit of firms or of products (at the country level) plays a small role during the crisis. Second, the sub-extensive margin defined as the churning of inputs within firms plays a sizable role in aggregate adjustment. This implies that the true increase in input costs exceeds that imputed from conventional price indices. Third, the relative importance of these margins and of overall trade adjustment varies with firm size. Motivated by these facts, we build a model of trade in intermediate inputs with heterogeneous firms, fixed import costs, and round-about production to evaluate the channels through which a collapse in imports affects TFP (total factor productivity) in manufacturing. Measured aggregate productivity in the sector depends on within-firm adjustments to the varieties imported as well as the joint distribution of each firm's technology and the share of imports in its total spending on inputs. We simulate an imported input cost shock and show that these mechanisms can deliver quantitatively significant declines in manufacturing TFP.

The Global Decline of the Labor Share

Abstract: The stability of the labor share of income is a key foundation in macroeconomic models. We document, however, that the global labor share has significantly declined since the early 1980s, with the decline occurring within the large majority of countries and industries. We show that the decrease in the relative price of investment goods, often attributed to advances in information technology and the computer age, induced firms to shift away from labor and toward capital. The lower price of investment goods explains roughly half of the observed decline in the labor share, even when we allow for other mechanisms influencing factor shares such as increasing profits, capital-augmenting technology growth, and the changing skill composition of the labor force. We highlight the implications of this explanation for welfare and macroeconomic dynamics.

About Capital in the Twenty-First Century

Abstract: In this article, I present three key facts about income and wealth inequality in the long run emerging from my book, Capital in the Twenty-First Century, and seek to sharpen and refocus the discussion about those trends. In particular, I clarify the role played by r > g in my analysis of wealth inequality. I also discuss some of the implications for optimal taxation, and the relation between capital-income ratios and capital shares.

Online Appendix to: The Next Generation of the Penn World Table*

Abstract: We describe the theory and practice of real GDP comparisons across countries and over time. Effective with version 8, the Penn World Table (PWT) will be taken over by the University of California, Davis and the University of Groningen, with continued input from Alan Heston at the University of Pennsylvania. Version 8 will expand on previous versions of PWT in three respects. First, it will distinguish real GDP on the expenditure side from real GDP on the output side, which differ by the terms of trade faced by countries. Second, it will distinguish growth rates of GDP based on national accounts data from growth rates that are benchmarked in multiple years to cross-country price data. Third, data on capital stocks will be reintroduced. Some illustrative results from PWT version 8 are discussed, including new results that show how the Penn effect is not emergent but a stable relationship over time.

Gravity Equations: Workhorse,Toolkit, and Cookbook

Abstract: This chapter focuses on the estimation and interpretation of gravity equations for bilateral trade. This necessarily involves a careful consideration of the theoretical underpinnings since it has become clear that naive approaches to estimation lead to biased and frequently misinterpreted results. There are now several theory-consistent estimation methods and we argue against sole reliance on any one method and instead advocate a toolkit approach. One estimator may be preferred for certain types of data or research questions but more often the methods should be used in concert to establish robustness. In recent years, estimation has become just a first step before a deeper analysis of the implications of the results, notably in terms of welfare. We try to facilitate diffusion of best-practice methods by illustrating their application in a step-by-step cookbook mode of exposition.
