We investigate the effect of climate change on population growth in 18th and 19th century Iceland. We find that annual temperature changes help determine the population growth rate in pre-industrial Iceland: a year 1 degree Celsius cooler than average drives down population growth rates by 1.14%. We also find that 18th and 19th century Icelanders adapt to prolonged changes in climate after 20 years. These adaptations reduce the short run effect of annual change in temperature by about 60%. Finally, a 1 degree Celsius sustained decrease in temperature decreases the steady state population by 10% to 26%.

In this comment, it is argued that a balanced-budget rule may cause underinvestment. As a consequence, such a rule is not ex ante efficient: in order to achieve the ex ante optimal outcome, it would be necessary to add an extra rule for the level of public investment. Unfortunately, however, such an investment rule is likely to be very difficult to implement in practice. When there are no rules to prevent underinvestment, it is no longer clear whether a balanced-budget rule is beneficial or not. In some cases, the cost of low levels of investment outweigh the benefits of a balanced budget.

It has long been hypothesized that individuals' migration propensities depend on their risk attitudes, but the empirical evidence has been limited and indirect. We use newly available data from the German Socio-Economic Panel to measure directly the relationship between migration and risk attitudes. We find that individuals who are more willing to take risks are more likely to migrate. Our estimates are substantial compared to unconditional migration probabilities, as well the effects of conventional determinants of migration, and are robust to controlling for a variety of demographic characteristics. We find no evidence that our results are the result of reverse causality.

Although the increase in non-GAAP earnings metrics has drawn unfavorable attention from regulators and standard setters, it can provide valuable experience for investors. We investigate whether experience with non-GAAP earnings metrics influences investors’ pricing of non-GAAP exclusions. We measure experience as the frequency with which managers or analysts provide non-GAAP earnings over the prior eight quarters and find that experience aids in the pricing of non-GAAP exclusions. Absent prior experience with non-GAAP earnings metrics, investors appear to overestimate the persistence of exclusions at the earnings announcement, which corrects in the following months. Cross-sectional tests suggest that experience facilitates investors’ pricing of non-GAAP exclusions by reducing their information processing costs.

We investigate whether multiemployer defined-benefit pension plan (MEPP) underfunding is priced by shareholders and creditors. Prior to the FASB's new MEPP standard (effective December 2011), when the disclosures on such plans were sparse, we find evidence (some evidence) that our estimate of a firm's share of MEPP underfunding is credit (value) relevant. We also find some evidence that a proxy for the funded status of a firm's MEPPs is incrementally value relevant over and above the firm's cash contributions, but no evidence that it is credit relevant. Furthermore, an estimate of MEPP underfunding that incorporates the additional disclosures required under the new MEPP standard is value and credit relevant, both individually and incrementally, over and above our old estimate. Overall, our findings suggest that shareholders and creditors view MEPP underfunding as a debt-like obligation and that the additional MEPP disclosures under the new standard are useful to market participants.

We argue that reductions in shareholder taxes should lower the cost of equity capital more for financially constrained firms than for other companies. Consistent with this prediction, we find that, following the 1997 (TRA) and the 2003 (JGTRRA) cuts in U.S. individual shareholder taxes, financially constrained firms enjoyed larger reductions in their cost of equity capital than did other firms. The results are consistent with the incidence of the tax reductions falling mostly on firms with both pressing needs for capital and disproportionate ownership by individuals, the only shareholders who benefited from the legislations. The paper provides a partial explanation for the seemingly puzzling finding that, following the unprecedented 2003 reduction in dividend tax rates, non-dividend-paying firms outperformed dividend-paying firms. The results suggest that it was not dividend status that mattered, but financial constraint, a common attribute of non-dividend-paying companies. Data Availability: Data are available from public sources identified in the study.

We show that collateral constraints restrict firm entry and postentry growth, using French administrative data and cross‐sectional variation in local house‐price appreciation as shocks to collateral values. We control for local demand shocks by comparing treated homeowners to controls in the same region that do not experience collateral shocks: renters and homeowners with an outstanding mortgage, who (in France) cannot take out a second mortgage. In both comparisons, an increase in collateral value leads to a higher probability of becoming an entrepreneur. Conditional on entry, treated entrepreneurs use more debt, start larger firms, and remain larger in the long run.

Asset prices contain information about the probability distribution of future states and the stochastic discounting of those states as used by investors. To better understand the challenge in distinguishing investors' beliefs from risk‐adjusted discounting, we use Perron–Frobenius Theory to isolate a positive martingale component of the stochastic discount factor process. This component recovers a probability measure that absorbs long‐term risk adjustments. When the martingale is not degenerate, surmising that this recovered probability captures investors' beliefs distorts inference about risk‐return tradeoffs. Stochastic discount factors in many structural models of asset prices have empirically relevant martingale components.
