Langlebigkeit und Altern: Gene oder Umwelt?

Aging is defined as loss of homeostasis which affects all metabolic systems, including DNA. Interspecies comparisons and lessons from the human genetic instability syndromes suggest a correlation between DNA-homeostasis and maximum lifespan, whereas average lifespan depends mainly on environmental factors. Current demographic data suggest a maximum lifespan in humans of 110–115. The average life expectancy at birth has reached 80 years in the wealthy nations and may exceed, at least in females, 90 years by the year 2050. Genetic and biological reasons, but also lifestyle factors, account for the greater longevity of women. Attempt to define a ?longevity“ genotype so far have not been met with success, but carriers of the ApoE4-Allele appear to have a disadvantage. Unlike the situation in model organisms, aging and longevity in humans seem to be influenced by numerous genes and environmental interactions. Most people do not die of old age but of age-related diseases which are frequent because of lack of natural selection against genetic defects that cause late-onset diseases. Moreover, genes causing late-onset diseases show evidence of antagonistic pleiotropy, rendering these genes resistant to removal from our genome. Likewise, thermoinstability of DNA and generation of reactive oxygen species during oxidative phosphorylation are two endogenous sources of genomic instability that limit our lifespan and cannot be overcome without fundamentally altering the biological make-up of our species. Genomic instability causes cancer and accelerates the aging process, as evidenced by the human caretaker gene syndromes which typically show progeroid features. From a genetic point of view, cancer and aging may be moderately delayed and / or mitigated by lifestyle and medical / environmental interventions, but given the constraints of our biological make-up, they cannot be eradicated.     

The Volatility and Price Sensitivities of Managerial Stock Option Portfolios and Corporate Hedging

We use estimates of the Black–Scholes sensitivity of managers' stock option portfolios to stock return volatility and the sensitivity of managers' stock and stock option portfolios to stock price to test the relationship between managers' risk preferences and hedging activities. We find that as the sensitivity of managers' stock and stock option portfolios to stock price increases, firms tend to hedge more. However, as the sensitivity of managers' stock option portfolios to stock return volatility increases, firms tend to hedge less.     

Spreads, Depths, and Quote Clustering on the NYSE and Nasdaq: Evidence after the 1997 Securities and Exchange Commission Rule Changes

This paper examines liquidity and quote clustering on the NYSE and Nasdaq using data after the two market reforms—the 1997 order–handling rule and minimum tick size changes. We find that Nasdaq–listed stocks exhibit wider spreads and smaller depths than NYSE–listed stocks and stocks with higher proportions of even–eighth and even–sixteenth quotes have wider quoted, effective, and realized spreads on both the NYSE and Nasdaq. This result differs from the findings by Bessembinder (1999, p. 404) that "trade execution costs on Nasdaq in late 1997 are no longer significantly explained by a tendency for liquidity providers to avoid odd–eighth quotations," and "odd–sixteenth avoidance has little relevance for explaining post–reform Nasdaq trading costs."

Assessing the international spillover effects of capital income taxation

Changes in capital taxes by one economy spill onto other economies with internationally mobile capital. We evaluate these impacts using a two-region, intertemporal general equilibrium model. The foreign economy's unilateral reduction in corporate income taxation has positive but small effects on U.S. welfare. In contrast, unilateral reductions in personal income taxation impose large negative spillovers. The differences result from CIT being source-based and PIT residence-based. The CIT cut reduces tax burdens to U.S. residents who invest abroad, while the PIT cut reduces foreigners' tax burdens only. Through general equilibrium adjustments neglected in simpler models, the PIT cut lowers U.S. residents' welfare.
