Do preoffer target stock price runups increase bidder takeover costs? We present model‐based tests of this issue assuming runups are caused by signals that inform investors about potential takeover synergies. Rational deal anticipation implies a relation between target runups and markups (offer value minus runup) that is greater than minus one‐for‐one and inherently nonlinear. If merger negotiations force bidders to raise the offer with the runup—a costly feedback loop where bidders pay twice for anticipated target synergies—markups become strictly increasing in runups. Large‐sample tests support rational deal anticipation in runups while rejecting the costly feedback loop.

From 1994 to 1998, Bradshaw (2004) finds that analysts' stock recommendations relate negatively to residual income valuation estimates (scaled by current price) but positively to valuation heuristics based on the price-to-earnings-to-growth ratio and long-term growth. These results are surprising, especially considering that future returns relate positively to residual income valuation estimates and negatively to heuristics. Using a large sample of analysts for the 1993–2005 period, we consider whether recent regulatory reforms affect this apparent inconsistent analyst behavior. Consistent with the intent of these reforms, we find that the negative relation between analysts' stock recommendations and residual income valuations is diminishing following regulations. We also show that residual income valuations, developed using analysts' earnings forecasts, relate more positively with future returns. However, we document that stock recommendations continue to relate negatively with future returns. We conclude that recent regulations have affected analysts' outputs—forecasted earnings and stock recommendations—but investors should be aware that factors other than identifying mispriced stocks continue to influence how analysts recommend stocks.

We use the Ohlson (1995, 1999) and Feltham and Ohlson (1999) valuation models to investigate the market's perception of the economic effect of employee stock options (ESOs) on firm value for a sample of 85 profitable computer software companies. Our results suggest that the market appears to value these firms' ESO expense not as an expense but as an intangible asset (even after controlling for the endogeneity bias arising from the mechanical relation between ESOs and the underlying stock prices). However, we also find a conflict between: (1) the positive manner in which investors appear to value ESO expense, and (2) the negative relation between current ESO expense and future abnormal earnings. This conflict not only could be an artifact of the restrictiveness of the abnormal earnings forecasting equation we estimate, but it also calls into question whether investors assess correctly the effect of ESOs on profitable software firm value.

Using a random judge design and panel data from Norway, we estimate that imprisonment discourages further criminal behavior, with reoffense probabilities falling by 29 percentage points and criminal charges dropping by 11 over a 5-year period. Ordinary least squares mistakenly reaches the opposite conclusion. The decline is driven by individuals not working prior to incarceration; these individuals increase participation in employment programs and raise their future employment and earnings. Previously employed individuals experience lasting negative employment effects. These findings demonstrate that time spent in prison with a focus on rehabilitation can be preventive for a large segment of the criminal population.

Two identical firms who start exporting in different months, one each in January and December, will report dramatically different exports for the first calendar year. This partial-year effect biases down first-year export levels and biases up first-year export growth rates. For Peruvian exporters, the partial-year bias is large: first-year export levels are understated by 54 percent and the first-year growth rate is overstated by 112 percentage points. Correcting the partial-year effect dramatically reduces first-year export growth rates, raises initial export levels, and almost doubles the contribution of net firm entry and exit to overall export growth.

In 1940 the labor force participation rate for married women, husband present, was 14 percent. By 1970 it had increased 26 percentage points to 40 percent. The supply and demand variables associated with this increase have been widely investigated. However, there has been ve'ry little research on the economic effects of wives' labor force participation. (See R. Agarwala and J. Drinkwater, Margaret Carroll, Robert Holbrook and Frank Stafford, Lucy Mallan and Jacob Mincer.) This paper analyzes two economic effects: the effect on the ratio of consumption to income (CIY) and the effect on the ratio of durable goods purchases to income (DurlY). The primary question addressed is: Controlling for total family income and several other variables, what are the differences (if any) in the ratios of CIY and DurlY for working-wife (W-W) and nonworking wife (N-W-W) families? Looked at in another way, the question may be rephrased: How do W-W families use wives' income?

We show that, among college graduates, earnings differentials across field of study have increased substantially since the early 1990s. We study the degree to which this increase can be accounted for by changes in the labor market return to skills associated with a major. To do so, we define major-specific measures of the relative importance of abstract, routine, and manual tasks on the job, by linking majors to the occupations they typically lead to. Changes in the relationship between earnings and these measures can account for about two-thirds of the rise in inequality.

This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and that product adding and dropping induce large changes in firm scope. The behavior we observe is consistent with a natural generalization of existing theories of industry dynamics that incorporates endogenous product selection within firms. Our findings suggest that product switching contributes to a reallocation of resources within firms toward their most efficient use.

Economywide Implications from US Bioenergy Expansion by Mark Gehlhar, Agapi Somwaru, Peter B. Dixon, Maureen T. Rimmer and Ashley R. Winston. Published in volume 100, issue 2, pages 172-77 of American Economic Review, May 2010

This paper provides empirical evidence about the effect of unearned income on earnings, consumption, and savings. Using an original survey of people playing the lottery in Massachusetts in the mid-1980's, we analyze the effects of the magnitude of lottery prizes on economic behavior. The critical assumption is that among lottery winners the magnitude of the prize is randomly assigned. We find that unearned income reduces labor earnings, with a marginal propensity to consume leisure of approximately 11 percent, with larger effects for individuals between 55 and 65 years old. After receiving about half their prize, individuals saved about 16 percent.
