"Since you're so rich, you must be really smart": Talent and the Finance Wage Premium
- 2018
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Wages in the financial sector have experienced an extraordinary increase over the last few decades. A proposed explanation for this trend has been that the demand for skill has risen more in finance compared to other sectors. We use Swedish administrative data, which include detailed cognitive and non-cognitive test scores as well as educational performance, to examine the implications of this hypothesis for talent allocation and relative wages in the financial sector. We find no evidence that the selection of talent into finance has improved, neither on average nor at the top of the talent and wage distributions. A changing composition of talent or their returns cannot account for the surge in the finance wage premium. While these findings alleviate concerns about a "brain drain" into finance at the expense of other sectors, they also suggest that finance workers are capturing substantial rents that have increased over time.

- Relative pay in the financial sector has experienced an extraordinary increase over the last few decades. A proposed explanation for this pattern has been that the demand for skilled workers in finance has risen more than in other sectors. We use Swedish administrative data, which include detailed cognitive and non-cognitive test scores as well as performance in high-school and university, to examine the implications of this hypothesis for talent allocation and relative wages in the financial sector. We find no evidence that the selection of talent into finance increased or improved, neither on average nor at the top of the talent distribution. A changing composition of talent or their returns cannot account for the surge in the finance wage premium. These findings alleviate concerns about a “brain drain” into finance at the expense of other sectors, but they also suggest that rents in finance are high, increasing, and largely unexplained.

- AimsAlthough routine invasive management is recommended in NSTEMI patients, the optimal timing of the procedure is not defined. The aim of this study was to assess outcomes in relation to timing of PCI in NSTEMI patients.Methods and resultsThis was an observational, prospective, multicentre cohort study from the SWEDEHEART registry including all Swedish PCI centres. We included 40 494 consecutive PCI-treated patients who were admitted to any coronary care unit from 2006 to 2013. The primary outcome was all-cause death, and secondary outcomes were recurrent myocardial infarction (MI), stent thrombosis, and severe in-hospital bleeding. Outcomes were assessed within 1 year from admission in relation to pre-specified cut-offs to define early PCI: within 1, 2, or 3 days. Patients who received delayed PCI, compared with those who did not, were older, and had a higher prevalence of comorbidities (hypertension, hyperlipidaemia, diabetes, and prior stroke) but showed similar angiographic findings. Cox mixed-effects models showed a lower risk of all-cause death with early PCI across all three cut-offs: HR (95% CI) of 0.88 (0.80–0.98), 0.78 (0.71–0.86), and 0.75 (0.68–0.84), for the 1-, 2-, and 3-day cut-offs, respectively. Early PCI was associated with lower risk of recurrent MI for the 2- and 3-day cut-offs, but not for the 1-day cut-off. The reported rates of severe in-hospital bleeding were low, but tended to be higher in patients receiving delayed PCI.ConclusionIn patients undergoing PCI for NSTEMI, early invasive treatment is associated with lower risk of ischaemic outcomes.

Biodiversity at multiple trophic levels is needed for ecosystem multifunctionality
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Many experiments have shown that loss of biodiversity reduces the capacity of ecosystems to provide the multiple services on which humans depend. However, experiments necessarily simplify the complexity of natural ecosystems and will normally control for other important drivers of ecosystem functioning, such as the environment or land use. In addition, existing studies typically focus on the diversity of single trophic groups, neglecting the fact that biodiversity loss occurs across many taxa and that the functional effects of any trophic group may depend on the abundance and diversity of others. Here we report analysis of the relationships between the species richness and abundance of nine trophic groups, including 4,600 above- and below-ground taxa, and 14 ecosystem services and functions and with their simultaneous provision (or multifunctionality) in 150 grasslands. We show that high species richness in multiple trophic groups (multitrophic richness) had stronger positive effects on ecosystem services than richness in any individual trophic group; this includes plant species richness, the most widely used measure of biodiversity. On average, three trophic groups influenced each ecosystem service, with each trophic group influencing at least one service. Multitrophic richness was particularly beneficial for 'regulating' and 'cultural' services, and for multifunctionality, whereas a change in the total abundance of species or biomass in multiple trophic groups (the multitrophic abundance) positively affected supporting services. Multitrophic richness and abundance drove ecosystem functioning as strongly as abiotic conditions and land-use intensity, extending previous experimental results to real-world ecosystems. Primary producers, herbivorous insects and microbial decomposers seem to be particularly important drivers of ecosystem functioning, as shown by the strong and frequent positive associations of their richness or abundance with multiple ecosystem services. Our results show that multitrophic richness and abundance support ecosystem functioning, and demonstrate that a focus on single groups has led to researchers to greatly underestimate the functional importance of biodiversity.

- Species diversity promotes the delivery of multiple ecosystem functions (multifunctionality). However, the relative functional importance of rare and common species in driving the biodiversity-multifunctionality relationship remains unknown. We studied the relationship between the diversity of rare and common species (according to their local abundances and across nine different trophic groups), and multifunctionality indices derived from 14 ecosystem functions on 150 grasslands across a land-use intensity (LUI) gradient. The diversity of above-and below-ground rare species had opposite effects, with rare above-ground species being associated with high levels of multifunctionality, probably because their effects on different functions did not trade off against each other. Conversely, common species were only related to average, not high, levels of multifunctionality, and their functional effects declined with LUI. Apart from the community-level effects of diversity, we found significant positive associations between the abundance of individual species and multifunctionality in 6% of the species tested. Species-specific functional effects were best predicted by their response to LUI: species that declined in abundance with land use intensification were those associated with higher levels of multifunctionality. Our results highlight the importance of rare species for ecosystem multifunctionality and help guiding future conservation priorities.
