The relevance of imperfect competition for models of aggregate economic fluctuations has received increased attention from researchers in both macroeconomics and industrial organization. Measuring properly the size of industry markups of price over marginal cost is important both for assessing...

Each of the main explanations of procyclical labor productivity, or short-run increasing returns to labor (SRIRL), is closely associated with a competing theory of the business cycle: Real business cycle theorists attribute SRIRL to procyclical technological shocks, proponents of recent theories...

This paper examines the seasonal cycle in the manufacturing sector of the U.S. economy. we present estimates of the seasonal patterns in monthly data for 2-digit industries, and we demonstrate the similarity of the seasonal cycle and the business cycle in manufacturing with respect to several...

This paper investigates whether U.S. government spending multipliers differ according to two potentially important features of the economy: (1) the amount of slack and (2) whether interest rates are near the zero lower bound. We shed light on these questions by analyzing new quarterly historical...

The NBER's pre-WWI chronology of annual peaks and troughs has the remarkable implication that the U.S. economy spent nearly every other year in recession, although previous research has argued that the post-Civil War dates are flawed. This paper extends that research by redating annual peaks and...

Economic policy uncertainty affects decisions of households, businesses, policy makers and Financial intermediaries. We first examine the impact of economic policy uncertainty on aggregate bank credit growth. Then we analyze commercial bank entity level data to gauge the effects of policy...

We develop a new methodology for quantifying the tasks undertaken within occupations using over 3,000 verbs from more than 12,000 occupational descriptions in the Dictionary of Occupational Titles (DOTs). Using micro-data from the United States from 1880-2000, we find an increase in the...

Industrial revolution in the United States first took hold in rural New England as factories arose and grew in a handful of industries such as textiles and shoes. However, as factory scale economies rose and factory production techniques were adopted by an ever growing number of industries,...
