Koldioxidinfångning direkt ur luften, dyrt idag – billigt i framtiden?
- 2019
-
Rapport (populärvet., debatt m.m.)abstract
- Sammanfattning i punktform:Om DAC med dagenskostnad skulle användas för uppfångning av koldioxid motsvarande världens årliga utsläpp, skulle det årligen kosta en summa motsvarande en fjärdedel av världsekonomin.Av de fåtal företag som bedriver direktuppfångning av atmosfärisk koldioxid (DAC) har bara ett av dessa offentliggjort sina kostnader. Företaget redovisar idag en kostnad som uppgår till 5600 SEKper insamlat ton.•Det finns dock stor potential för minskade kostnader över tid.Osäkerheten i denna potential är mycketstor eftersom innovation, lärkurvor och energipriser generellt är svåra att uppskatta på längre sikt.Efter en bästa gissning baserat på liknande kostnadsminskningar som för ex. solceller och vindkraft uppskattar vi kostnaderna för DAC att sjunka till ca. 750 SEK/tCO2 år 2050, eller någonstans mellan 168–2092 SEK.Med utvecklingstakten ovan blir DAC samhällsekonomiskt lönsamt omkring år 2045.För att nå denna potential krävs kraftiga investeringar i stöttande infrastruktur för snabb uppskalning och ekonomiska incitament för infångande (och senare lagring) av koldioxid.Koldioxidskatter och andra typer av policyåtgärderpåverkar när DAC:s blir lönsam.

Entrepreneurship and income inequality
- 2018

Tidskriftsartikel (populärvet., debatt m.m.)abstract
- Entrepreneurship research highlights entrepreneurship as a simultaneous source of enhanced income mobility for some but a potential source of poverty for others. Research on inequality has furthered new types of models to decompose and problematize various sources of income inequality, but attention to entrepreneurship as an increasingly prevalent occupational choice in these models remains scant. This paper seeks to bridge these two literatures using regression-based income decomposition among entrepreneurs and paid workers distinguishing between self-employed (SE) and incorporated self-employed (ISE) individuals in Sweden. We find that the proportion of self-employed in the workforce increases income dispersion by way of widening the bottom end of the distribution, whereas the proportion of incorporated self-employed contributes to income dispersion at the top end of the distribution. Implications for research are discussed. (C) 2017 The Authors. Published by Elsevier B.V.

Entreprenörskap och inkomstspridning : hur företagare påverkar ojämlikheten
- 2017
-
Ingår i: Ekonomisk Debatt. - Stockholm, Sverige : Nationalekonomiska Föreningen. - 0345-2646. ; 45:1, s. 53-59
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Forskningen om inkomstojämlikhet har utvecklat modeller för att analysera inkomstspridning men har underlåtit att inkludera entreprenörskap – ett allt vanligare yrkesval. Vi undersöker hur antalet och typen av företagare påverkar inkomstskillnaderna i Sverige. Vi finner en tydlig polariseringseffekt av andelen företagare i arbetskraften: Egenföretagare ökar inkomstspridningen genom att flertalet har låga inkomster relativt löntagare, medan det omvända gäller för aktiebolagsföretagare. Påverkan sker således främst i svansarna av fördelningen, och den tycks vara som störst för egenföretagare.

Globalization and Uncertainty : Earnings Volatility in Sweden, 1985-2003
- 2010
-
Ingår i: Industrial Relations. - 0019-8676 .- 1468-232X. ; 49:2, s. 165-189
-
Tidskriftsartikel (refereegranskat)abstract
- Earnings volatility has been linked to economic integration only through contradictory conjectures. We assess globalization's role by examining volatility trends in manufacturing, private services, and public services. If trade increases uncertainty, volatility trends should differ markedly across industries since manufacturing, in contrast to especially public services, is exposed to international competition. We analyze earnings trajectories in Sweden 1985–2003, a country and period evincing accelerating trade, finding no indications of greater volatility increases in manufacturing.

Does size of local labour markets affect wage inequality? : a rank-size rule of income distribution
- 2008
-
Ingår i: Journal of Economic Geography. - : Oxford University Press (OUP): Policy F. - 1468-2710 .- 1468-2702. ; 8:2, s. 211-237
-
Tidskriftsartikel (refereegranskat)abstract
- The questions addressed in this paper are: (i) does wage inequality increase with local population size, and if so, (ii) what are possible factors behind this increase? In a cross-section analysis of Swedish local labour markets using unique full population data, the article shows that urban scale, i.e. size of local population, has significant positive effects on wage inequality. Testing for potential explanations, labour market diversification, human capital, migration, age structure and employment are shown to be significantly associated with inequality. Given these effects, the article raises the question of how to understand and incorporate scale effects into models of long-term change in wage inequality.

Human Capital Theory and Internal Migration : Do Average Outcomes Distort Our View of Migrant Motives?
- 2013
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Empirical studies on internal labor migration are usually based on observed patterns of net flows into local labor markets with relatively lower unemployment and relatively higher real wages. Evidence here suggests that internal migrants move to enhance returns to their labor. In contrast, major surveys in the USA, the UK and Australia show that less than a third of internal migrants are motivated primarily by employment reasons. A possible explanation for this disconnect revolves around average and individual outcomes from migration. Using a sample of 39 000 Swedish regional migrants, this paper addresses this disconnect by examining the distribution of short and long term migrant income changes, and the factors that predict their placement within this distribution. We show that returns to migration do matter, especially for the more educated migrants. Overall, however, about a third of all migrants had negative short term returns to migration and about 40 percent make below median gains even in the long run. The data support a view that average outcomes are an insufficient way to measure the role of human capital motivated migration.

Human capital theory and internal migration: Do average outcomes distort our view of migrant motives?
- 2017
-
Ingår i: Migration Letters. - : Transnational Press London. - 1741-8992 .- 1741-8984. ; 14:2, s. 237-250
-
Tidskriftsartikel (refereegranskat)abstract
- By modelling the distribution of percentage income gains for movers in Sweden, using multinomial logistic regression, this paper shows that those receiving large pecuniary returns from migration are primarily those moving to the larger metropolitan areas and those with higher education, and that there is much more variability in income gains than what is often assumed in models of average gains to migration. This suggests that human capital models of internal migration often overemphasize the job and income motive for moving, and fail to explore where and when human capital motivated migration occurs. © Transnational Press London.
