Given the slowdown in labor productivity growth in the mid-2000s, some have argued that the boost to labor productivity from IT may have run its course. This paper contributes three types of evidence to this debate. First, we show that since 2004, IT has continued to make a significant contribution to labor productivity growth in the United States, though it is no longer providing the boost it did during the productivity resurgence from 1995 to 2004. Second, we present evidence that semiconductor technology, a key ingredient of the IT revolution, has continued to advance at a rapid pace and...

The decline in U.S. real GDP growth volatility after the mid 1980s was an outcome of more risk efficient and more diversified sectoral allocations. Using a portfolio approach, I distinguish between the two determinants of GDP growth volatility: sectoral covariances and sectoral allocations. I use the sectoral growth and covariances to compute the growth-volatility frontier of the economy. I define the efficiency of the actual sectoral allocation as the distance of the economy from the frontier, measured in the (volatility, growth) space. There are three main findings. 1) The frontier has...

This paper offers two contributions to the literature on taxpayer perceptions of the tax system. Our first contribution is that we develop a model that generates predictions over how taxpayers update their beliefs about their marginal tax rates when they experience an unexpected change in their tax liability. Our model is an extension of a standard full information, rational agent model that allows for imperfect knowledge of the income tax schedule. In the model, a household is subject to a linear tax schedule that changes from year to year. The household perceives innovations to the tax...

What are the consequences of a potential fire sale stemming from the exemption of repurchase agreements (repos) from automatic stay? This paper shows that repo's exemption from stay alters firms' financing and investment decisions ex ante. Specifically, a stay exemption changes firms' investment opportunity set, enabling them to purchase assets of defaulted firms at fire sale prices. Fire sales arise endogenously because of limited capital available to purchase collateral posted by insolvent firms, i.e., cash-in-the-market pricing. A fire sale effectively creates a premium for holding on to...

We examine the effects of government policy uncertainty on cross-border capital flows. FDI flows from US companies to foreign affiliates drop significantly during the period just before an election. The election effect for FDI is larger than election cycles in domestic investment. The electoral patterns in FDI flows are more pronounced in countries with higher propensities for policy reversals and when election outcomes are more uncertain. Our identification strategy compares variation in different types of capital flows into the same country around the timing of national elections. The...

This book presents the first comprehensive test of whether well-known conflicts of interest at bond rating agencies importantly influence their actions. This hypothesis is tested against the alternative that rating agency actions are primarily influenced by a countervailing incentive to protect their reputations as delegated monitors. These two hypotheses generate a number of testable predictions regarding the anticipation of credit-rating downgrades by the bond market, which we investigate using a new data set of about 2,000 credit rating migrations from Moody's and Standard & Poor's, and...

The Federal Reserve Board tested and found supporting evidence for the precautionary motive hypothesis of liquidity hoarding for U.S. commercial banks during the recent financial crisis. They also found that banks held more liquid assets in anticipation of future losses from securities write-downs. Exposure to securities losses in their investment portfolios and expected loan losses (measured by loan loss reserves) represent key measures of banks' on-balance sheet risks, in addition to off-balance sheet liquidity risk stemming from unused loan commitments. Furthermore, unrealized securities...
