In recent decades, American workers have faced a rising college premium, a narrowing gender gap, and increasing wage volatility. This paper explores the quantitative and welfare implications of these changes. The framework is an incomplete-markets life cycle model in which individuals choose education, intrafamily time allocation, and savings. Given the observed history of the U.S. wage structure, the model replicates key trends in cross-sectional inequality in hours worked, earnings, and consumption. Recent cohorts enjoy welfare gains, on average, as higher relative wages for college graduates and for women translate into higher educational attainment and a more even division of labor within the household.

Why do firms cluster near one another? We test Marshall's theories of industrial agglomeration by examining which industries locate near one another, or coagglomerate. We construct pairwise coagglomeration indices for US manufacturing industries from the Economic Census. We then relate coagglomeration levels to the degree to which industry pairs share goods, labor, or ideas. To reduce reverse causality, where collocation drives input-output linkages or hiring patterns, we use data from UK industries and from US areas where the two industries are not collocated. All three of Marshall's theories of agglomeration are supported, with input-output linkages particularly important. (JEL L14, L60, O33, R23, R32)

ABSTRACT: This study investigates whether individual top executives have incremental effects on their firms’ tax avoidance that cannot be explained by characteristics of the firm. To identify executive effects on firms’ effective tax rates, we construct a data set that tracks the movement of 908 executives across firms over time. Results indicate that individual executives play a significant role in determining the level of tax avoidance that firms undertake. The economic magnitude of the executive effects on tax avoidance is large. Moving between the top and bottom quartiles of executives results in approximately an 11 percent swing in GAAP effective tax rates; thus, executive effects appear to be an important determinant in firms’ tax avoidance.

ABSTRACT Motivated by the literature on investment flows and optimal trading, we examine intraday predictability in the cross‐section of stock returns. We find a striking pattern of return continuation at half‐hour intervals that are exact multiples of a trading day, and this effect lasts for at least 40 trading days. Volume, order imbalance, volatility, and bid‐ask spreads exhibit similar patterns, but do not explain the return patterns. We also show that short‐term return reversal is driven by temporary liquidity imbalances lasting less than an hour and bid‐ask bounce. Timing trades can reduce execution costs by the equivalent of the effective spread.

ABSTRACT: FIN No. 48, Accounting for Uncertainty in Income Taxes (FASB 2006), requires firms to disclose tax reserves and to record changes in tax reserves at adoption of FIN No. 48 as cumulative effect adjustments in stockholders’ equity. We predict that between the enactment and adoption of FIN No. 48, relative to historical levels, firms settle disputes more often to potentially decrease visibility to the IRS and release reserves more often to reduce scrutiny and increase earnings (as opposed to retained earnings). We analyze 2005 and 2006 10-Qs and 10-Ks for the 100 largest nonfinancial, nonutility firms followed by analysts. Between enactment and adoption of FIN No. 48, relative to historical levels, firms report more settlements with tax authorities and release reserves more frequently. In addition, firms with higher IRS deficiencies are more likely to settle disputes. Between enactment and adoption of FIN No. 48, firms increased earnings by releasing $4.4 billion of tax reserves, nearly equaling the $4.5 billion released at adoption.
