Structural Change in Labor Supply and Cross-Country Differences in Hours Worked
This paper studies how structural change in labor supply along the development spectrum shapes cross-country differences in hours worked. We emphasize two main forces: sectoralreallocation from self-employment to wage work, and declining fixed costs of wage work. We show that these forces are crucial for understanding how the extensive margin (the employment rate) and intensive margin (hours per worker) of aggregate hours worked vary with income per capita. To do so we build and estimate a quantitative model of labor supply featuring a traditional self-employment sector and a modern ...

Macroeconomic Changes with Declining Trend Inflation: Complementarity with the Superstar Firm Hypothesis
Recent studies indicate that, since 1980, the average markup and the profit share of income have increased, while the labor share and the investment share of spending have decreased. We examine the role of monetary policy in these changes as inflation has concurrently trended down. In a simple staggered price model with a non-CES aggregator of differentiated goods, a decline in trend inflation as measured since 1980 can account for a substantial portion of the changes. Moreover, introducing a rise in the productivity of “superstar firms” in the model can better explain not only the ...

Externalities, Endogenous Productivity, and Poverty Traps
We present a version of the neoclassical model with an endogenous industry structure. We construct a distribution of firms? productivity that implies multiple steady-state equilibria even with an arbitrarily small degree of increasing returns to scale. While the most productive firms operate across all the steady states, in a poverty trap less productive firms operate as well. This results in lower average firm productivity and total factor productivity. The distributions of employment by firm size across steady states are consistent with the empirical observation that poor countries have a ...

Cost-Price Relationships in a Concentrated Economy
We use local projections with granular instrumental variables to estimate the aggregate pass-through of costs into prices and how it is affected by industry concentration. On average, we find, prices increase above trend growth for three quarters after an exogenous cost shock, and the price increase is accompanied by a decline in output. The estimated pass-through of the shock into prices one quarter ahead is 0.7. The price response to shocks becomes about 27 percent larger when there is an increase in concentration similar to the one observed over the last 20 years. This differential effect ...

Structural Change and Global Trade
Services, which are less traded than goods, rose from 58 percent of world expenditure in 1970 to 79 percent in 2015. Using a Ricardian trade model incorporating endogenous structural change, we quantify how this substantial shift in consumption has affected trade. Without structural change, we find that the world trade to GDP ratio would be 15 percentage points higher by 2015, about half the boost delivered from declining trade costs. In addition, this structural change has lowered the global welfare gains from trade integration by almost 40 percent over the past four decades. Absent further ...

Accounting for Innovations in Consumer Digital Services: IT still matters
This paper develops a framework for measuring digital services in the face of ongoing innovations in the delivery of content to consumers. We capture what Brynjolfsson and Saunders (2009) call "free goods" as the capital services generated by connected consumers' stocks of IT digital goods; this service flow augments the existing measure of personal consumption in GDP. Its value is determined by the intensity with which households use their IT capital to consume content delivered over networks, and its volume depends on the quality of the IT capital. Consumers pay for delivery services, ...

Cost-Price Relationships in a Concentrated Economy
The US economy is at least 50 percent more concentrated today than it was in 2005. In this paper, we estimate the effect of this increase on the pass-through of cost shocks into prices. Our estimates imply that the pass-through becomes about 25 percentage points greater when there is an increase in concentration similar to the one observed since the beginning of this century. The resulting above-trend price growth lasts for about four quarters. Our findings suggest that the increase in industry concentration over the past two decades could be amplifying the inflationary pressure from current ...

The increasing importance of services expenditures and the dampening effect on global trade
Globalization, particularly through international trade in goods, has helped to foster the creation of tremendous amounts of wealth and prosperity across much of the globe while lifting sizable portions of the world’s population out of poverty. In particular, the latter half of the twentieth century delivered unprecedented rates of increased economic integration among many countries. Access to global markets supported the industrialization of emerging economies and opened up new markets for firms in wealthier countries. As a result of the expansion of international trade and competition, ...

Industrial production and capacity utilization: 1998 annual revision
In late 1998, the Federal Reserve published the results of an annual revision of its measures of industrial production, capacity, and capacity utilization, which cover the nation's manufacturing, mining, and electric and gas utilities industries. The revision involved both the incorporation of newly available and more comprehensive source data and, for some series, the introduction of modified methods for compiling the series. The revised figures show stronger growth of both production and capacity since 1996; however, the overall capacity utilization rate was little changed from the previous ...
