The Tropical Niche Conservatism hypothesis is a leading explanation for why biodiversity increases towards the equator. The model suggests that most lineages have tropical origins, with few dispersing into temperate regions. However, biotas are comprised of lineages with differing geographical origins, thus it is unclear whether lineages that originated on different continents will exhibit simi...

Using a large sample of listed firms from 17 European countries that mandatorily adopted IFRS over the period 2005-2008, we examine the effect of mandatory IFRS adoption on accounting conservatism defined using Basu’s (1997) differential timeliness (DT) measure. An important distinction of our study is that we avoid the common criticisms of the DT measure by comparing the difference in the DT m...

We develop a model to analyze how corporate governance and managerial optimism affect firms’financial reporting choices, and managers’incentives to manipulate accounting reports. Conservative accounting is advantageous because it enables boards to act on bad news and block investment ideas that are unattractive to shareholders but attractive to management. This feature of conservatism, however,...

The degree to which organisms retain their environmental preferences is of utmost importance in predicting their fate in a world of rapid climate change. Notably, marine invertebrates frequently show strong affinities for either carbonate or terrigenous clastic environments. This affinity is due to characteristics of the sediments as well as correlated environmental factors. We assessed the con...

Analyses of phylogenetic niche conservatism (PNC) are becoming increasingly common. However, each analysis makes subtly different assumptions about the evolutionary mechanism that generates patterns of niche conservatism. To understand PNC, analyses should be conducted with reference to a clear underlying model, using appropriate methods. Here, we outline five macroevolutionary models that may ...

Recent studies show that regression-based tests of the asymmetric timeliness of earnings may be invalid. We develop an econometric model showing that these tests correctly identify whether or not earnings are conservative; however, the inclusion of future rents in equity values causes the regression coefficients to mismeasure the degree of conservatism. This mismeasurement biases cross-sectiona...

In two large samples (combined N 1⁄4 31,045), we found a positive relationship between disgust sensitivity and political conservatism. This relationship held when controlling for a number of demographic variables as well as the ‘‘Big Five’’ personality traits. Disgust sensitivity was also associated with more conservative voting in the 2008 U.S. presidential election. In Study 2, we replicated ...

We reconsider the role of an inflation conservative central banker in a setting with distortionary taxation. To do so, we assume monetary and fiscal policy are decided by independent authorities that do not abide to past commitments. If the two authorities make policy decisions simultaneously, inflation conservatism causes fiscal overspending. But if fiscal policy is determined before monetary ...
