Tax return information is often complex and difficult to interpret. Whether its public availability benefits unsophisticated users remains an empirical question. This study examines whether disclosure of tax affects asymmetry among more- less- sophisticated investors. I investigate the unique setting mandatory three bottom-line income items in Australia. Using a difference-in-difference design ...

The relationship between species number and island area is a fundamental rule in ecology. However, the extent to which interactions with exotic species and how the structure of species interactions is related to island area remain unexplored. Here, I document the relationship between island area and (i) interactions with exotic species and (ii) network structure of species interactions in the c...

We analyze a class of models for unequal crossover (UC) of sequences containing sections with repeated units that may differ in length. In these, the probability of an 'imperfect' alignment, in which the shorter sequence has d units without a partner in the longer one, scales like qd as compared to 'perfect' alignments where all these copies are paired. The class is parameterized by this penalt...

Manual dexterity declines with increasing age, however, the way in which inter-manual asymmetry responds to aging is unclear. Our purpose was to determine the effect of age and practice on inter-manual performance asymmetry in an isometric force pinch line tracing task that varied in difficulty within segments. Thirty right-handed participants, five males and five females in each of three age g...
