Identifying Government Spending Shocks: It's all in the Timing*

Quarterly Journal of Economics 2011 126(1), 1-50 open access
Do shocks to government spending raise or lower consumption and real wages? Standard VAR identification approaches show a rise in these variables, whereas the Ramey-Shapiro narrative identification approach finds a fall. I show that a key difference in the approaches is the timing. Both professional forecasts and the narrative approach shocks Granger-cause the VAR shocks, implying that the VAR shocks are missing the timing of the news. Simulations from a standard neoclassical model in which government spending is anticipated by several quarters demonstrate that VARs estimated with faulty timing can produce a rise in consumption even when it decreases in the model. Motivated by the importance of measuring anticipations, I construct two new variables that measure anticipations. The first is based on narrative evidence that is much richer than the Ramey-Shapiro military dates and covers 1939 to 2008. The second is from the Survey of Professional Forecasters, and covers the period 1969 to 2008. All news measures suggest that most components of consumption fall after a positive shock to government spending. The implied government spending multipliers range from 0.6 to 1.1.

Competition and Product Quality in the Supermarket Industry

Quarterly Journal of Economics 2011 126(3), 1539-1591 open access
This article analyzes the effect of competition on a supermarket firm's incentive to provide product quality. In the supermarket industry, product availability is an important measure of quality. Using U.S. Consumer Price Index microdata to track inventory shortfalls, I find that stores facing more intense competition have fewer shortfalls. Competition from Walmart—the most significant shock to industry market structure in half a century—decreased shortfalls among large chains by about a third. The risk that customers will switch stores appears to provide competitors with a strong incentive to invest in product quality.

The effects of bank relations on stock repurchases: Evidence from Japan

Journal of Financial Intermediation 2011 20(1), 94-116 open access
This paper examines the effects that bank relations have on stock repurchases in Japan. Similar to US evidence, we find that stock repurchase announcements in Japan have positive announcement period returns. Announcement returns are positively related to equity ownership by main banks, but are negatively related to nonbank debt ratios. In contrast, bank debt ratios do not have such a negative relation. Announcement returns are also negatively related to future growth opportunities, suggesting that repurchase announcements are greeted more positively by investors when repurchasing firms have lower growth opportunities. We also find that firms with high leverage are less likely to repurchase stocks, whereas firms with high equity ownership by main banks are more likely to do so. Overall, these results are consistent with the views that banks, particularly main banks, are effective monitors of agency costs and financial distress risk, and that their presence as dual stakeholders are value-enhancing.

Pension plan accounting estimates and the freezing of defined benefit pension plans

Journal of Accounting and Economics 2011 51(1-2), 115-133
This study provides evidence that, when “hard” freezing their defined benefit pension plans, employers select downward biased accounting assumptions to exaggerate the economic burden of their benefit plans. Downward biased expected rates of return and discount rates allow managers to increase reported pension expenses and, for discount rates, allow managers to increase reported pension liabilities. We find that prior to the Sarbanes-Oxley Act, both rates are downward biased when firms freeze their plans, whereas after SOX the bias is lower. This finding is consistent with managers opportunistically biasing pension estimates to obtain labor concessions during periods of reduced regulatory scrutiny.

Institutional tax clienteles and payout policy

Journal of Financial Economics 2011 100(1), 68-84
This paper employs heterogeneity in institutional shareholder tax characteristics to identify the relation between firm payout policy and tax incentives. Analysis of a panel of firms matched with the tax characteristics of the clients of their institutional shareholders indicates that “dividend-averse” institutions are significantly less likely to hold shares in firms with larger dividend payouts. This relation between the tax preferences of institutional shareholders and firm payout policy may reflect dividend-averse institutions gravitating towards low dividend paying firms or managers adapting their payout policies to the interests of their institutional shareholders. Evidence is provided that both effects are operative. Plausibly exogenous changes in payout policy result in shifting institutional ownership patterns. Similarly, exogenous changes in the tax cost of institutional investors receiving dividends results in changes in firm dividend policy.

Self-fulfilling Credit Market Freezes

Review of Financial Studies 2011 24(11), 3519-3555
[This article develops a model of a self-fulfilling credit market freeze and uses it to study alternative governmental responses to such a crisis. We study an economy in which operating firms are interdependent, where their success depends on the ability of other operating firms to obtain financing. In such an economy, an inefficient credit market freeze may arise in which banks abstain from lending to operating firms with good projects because of their self-fulfilling expectations that other banks will not be making such loans. Our model enables us to study the effectiveness of using alternative measures as a means of getting an economy out of an inefficient credit market freeze. In particular, we study the effectiveness of interest rate cuts, an infusion of capital into banks, direct lending by the government to operating firms, and the provision of government capital or guarantees to encourage privately managed lending. Our analysis provides a framework for analyzing and evaluating the standard and nonstandard instruments used by authorities during the 2008-2009 financial crisis. Our analysis also provides testable implications for how firms, banks, and economies can be expected to be affected by shocks to the banking system.]

A Theory of Debt Market Illiquidity and Leverage Cyclicality

Review of Financial Studies 2011 24(10), 3369-3400
[We analyze determinants of secondary debt market liquidity, identifying conditions under which a large investor can profitably buy stakes from small bondholders and offer unilateral debt relief to a distressed firm. We show that endogenous trading by small bondholders may result in multiple equilibria. Some equilibria entail vanishing liquidity and sharp increases in yields absent changing fundamentals. In turn, anticipation of illiquid equilibria induces firms to eschew public debt financing, since such equilibria create higher bankruptcy costs and debt illiquidity discounts. The model thus offers a rational micro-foundation for stylized facts commonly attributed to investor sentiment and CFO market timing. Finally, we show that the vulnerability of debt markets to multiple equilibria is highest during downturns, when small bondholders face severe adverse selection.]

How Q and Cash Flow Affect Investment without Frictions: An Analytic Explanation

Review of Economic Studies 2011 78(4), 1179-1200 open access
We derive a closed-form solution for Tobin's Q in a stochastic dynamic framework. We show analytically that investment is positively related to Tobin's Q and cash flow, even in the absence of adjustment costs or financing frictions. Both Q and investment move in the same direction as expected revenue growth, so changes in expected revenue growth induce Q and investment to comove positively. Similarly, shocks to current cash flow, arising from shocks to the user cost of capital in our model, cause investment and cash flow per unit of capital to comove positively. Furthermore, we show that this alternative mechanism for the relationship among investment, Q, and cash flow delivers larger cash flow effects for smaller- and faster-growing firms, as observed in the data. Moreover, the empirically small sensitivity of investment to Tobin's Q does not imply implausibly large adjustment costs in our model (since there are no adjustment costs). Calibrating the model generates values of Q similar to those in the data; investment is more sensitive to cash flow than it is to Q, and both responses are of empirically plausible magnitudes.
