In new microbial-biogeochemical models, microbial carbon use efficiency (CUE) is often assumed to decline with increasing temperature. Under this assumption, soil carbon losses under warming are small because microbial biomass declines. Yet there is also empirical evidence that CUE may adapt (i.e., become less sensitive) to warming, thereby mitigating negative effects on microbial biomass. To a...

This will enable an evaluation of the Return On Investment (ROI) using the new concept of Yield Index “e-lYI” (e-learning Yield Index), introduced in this study. The Yield Index “e-lYI” suggests an original way to evaluate the implementation of e-learning methodologies into campus based environments; still, the new index will help professionals involved in the management of the transition from ...

This study investigates whether personal taxes are related to asset valuations. The effective tax rate of investment income fluctuated considerably since federal income taxes were introduced. The main result of the paper demonstrates that there is an economically and statistically significant relationship between asset valuations and personal tax rates. Stock valuations tend to be higher when t...

sustained is by omitting any reference to the sensation novels thronged with palpably nervous middle-class bodies which gave rise during the 1860s to a fury of indignation. "The reader's nerves are affected like the hero's", Margaret Oliphant stridently complained in a review of the most famous of them all, Wilkie Collins's The woman in white (1860). Such omissions make Nerves and narratives, a...

This paper quantitatively examines the empirical plausibility of equilibrium indeterminacy and sunspot-driven cyclical fluctuations in a real business cycle model with two distinct production sectors that yield consumption and investment goods, together with separable or non-separable preferences. When calibrated to match the observed progressivity of the U.S. federal individual income tax sche...

Taxation and risk taking are examined in a general equilibrium mode/ that incorporates uncertain government revenue and allows the government to influence risk through portfolio investments as well as through tax r policy. It is demonstra ted that each of a wide range of taxes can be decomposed into some combina tion of a wage tax, an ex ante wealth tax, and a modification of the government’s i...
