Optimal retail location and CO2 emissions

In this paper, the p-median model is used to find the location of retail stores that minimizes CO2 emissions from consumer travel. The optimal location is then compared with the existing retail location,and the excess CO2 emissions compared with the optimal solution is calculated. The results show that by using the environmentally optimal location, CO2 emissions from consumer travel could be reduced by approximately 25percent. 

The effects of taxing truck distance on CO2 emissions from transports in retailing

To finance transportation infrastructure and to address social and environmental negative externalities of road transports, several countries have recently introduced or consider a distance based tax on trucks. In the competitive retail market such tax can be expected to lower the demand and thereby reduce CO2 emissions of road transports. However, as we show in this paper, such tax might also slow down the transition towards e-tailing. Considering that previous research indicates that a consumer switching from brick-and-mortar shopping to e-tailing reduces her CO2 emissions substantially, the direction and magnitude of the environmental net effect of the tax is unclear. In this paper, we assess the net effect in a Swedish regional retail market where the tax not yet is in place. We predict the net effect on CO2 emissions to be positive, but off-set by about 50% because of a slower transition to e-tailing.

Are central bank independence reforms necessary for achieving low and stable inflation?

Using data on the occurence of central bank independence (CBI) reforms in 131 countries during 1980-2005, we test whether they were important in reducing inflation and maintaining price stability. CBI reforms are found to have reduced inflation on average 3.31% when countries with historically high inflation rates are included. But countries with lower inflation have reduced it without institutional reforms granting central banks more independence, undermining the theoretical time-inconsistency case for CBI. There is furthermore no evidence that CBI reforms have helped reduce inflation variability.

When IKEA enters : Do local retailers win or lose?

IKEA is one of the world’s largest retailers, but little is known about how IKEA impact incumbent retailers when deciding to enter a local market. Previous studies on the effects of big-box entry on surrounding retailers have also generated inconclusive results, and mainly been focused towards entry of Wal-Mart in the United States. We contribute to this literature by investigating the effects of IKEA entry on revenues and employment for incumbent retail firms in three Swedish municipalities during 2000-2010. Our results indicate that a new IKEA store increases average revenues for incumbent retailers within the entry municipality by 11%, but also that the effect is highly heterogeneous within the municipality. Retailers that were located up to 1 km from IKEA experienced a 26% increase in revenues when IKEA entered the municipality. However, the positive spillover effect of a new IKEA store on retail revenues diminished with the distance to IKEA, and turned insignificant for retailers in the city centers and those that were located 5-10 km from IKEA. The effects on employment were much less pronounced, and in most cases statistically insignificant.

Vår bästa tid är nu? : Om tidsuppfattning och politisk självförståelse

Our best time is now? On conception of time and political self-understanding This study regards time as a horizon for action and argues that conception of time has great implication for political self-understanding. In the study, the modern conception of time, with its orientation towards the future, is contrasted with the late modern conception of time, which is characterized by a de-legitimization of utopian thinking and by an orientation towards the present. Political action is changing, from a transformation of the present into the future, to a management of the present. In this situation the future is not perceived as something qualitatively different than present, but is, as Helga Nowotny puts it, reduced to an ‘extended present’. Or, to speak with Luhmann, the future is a ‘present future’ where only one ‘future present’ is conceivable. The future is in that sense increasingly closed. The paper argues that the current pragmatization of politics is partly due to changes in temporal representations, and suggests that more attention should be given to temporal semantics in political analysis.

Measuring CO2 emissions induced by online and brick-and-mortar retailing

We develop a method for empirically measuring the difference in carbon footprint between traditional and online retailing (“e-tailing”) from entry point to a geographical area to consumer residence. The method only requires data on the locations of brick-and-mortar stores, online delivery points, and residences of the region’s population, and on the goods transportation networks in the studied region. Such data are readily available in most countries, so the method is not country or region specific. The method has been evaluated using data from the Dalecarlia region in Sweden, and is shown to be robust to all assumptions made. In our empirical example, the results indicate that the average distance from consumer residence to a brick-and-mortar retailer is 48.54 km in the studied region, while the average distance to an online delivery point is 6.7 km. The results also indicate that e-tailing increases the average distance traveled from the regional entry point to the delivery point from 47.15 km for a brick-and-mortar store to 122.75 km for the online delivery points. However, as professional carriers transport the products in bulk to stores or online delivery points, which is more efficient than consumers’ transporting the products to their residences, the results indicate that consumers switching from traditional to e-tailing on average reduce their CO2 footprints by 84% when buying standard consumer electronics products.

Predicting entry of Swedish wholesale firms into local markets

Applying microeconomic theory, we develop a forecasting model for firm entry into local markets and test this model using data from the Swedish wholesale industry. The empirical analysis is based on directly estimating the profit function of wholesale firms. As in previous entry studies, profits are assumed to depend on firm- and location-specific factors,and the profit equation is estimated using panel data econometric techniques. Using the residuals from the profit equation estimations, we identify local markets in Sweden where firm profits are abnormally high given the level of all independent variables included in the profit function. From microeconomic theory, we then know that these local markets should have higher net entry than other markets, all else being equal, and we investigate this in a second step,also using a panel data econometric model. The results of estimating the net-entry equation indicate that four of five estimated models have more net entry in high-return municipalities, but the estimated parameter is only statistically significant at conventional levels in one of our estimated models.

Osynliga jobbskapare : En tillväxtpotential för svensk detaljhandel?

Den stora merparten av alla detaljhandelsföretag karakteriseras av ingen eller en marginell tillväxt av antalet anställda. Dessa företag betraktas ofta som en homogen grupp bestående av företag med inga tillväxtambitioner och som näringspolitiken inte bör inriktas gentemot. I denna rapport visar vi dock att de företag som inte växer i själva verket är mycket heterogena. Mer än tio procent av alla detaljhandelsföretag som inte växer under en treårsperiod kännetecknas av en relativt hög lönsamhet. Dessa företag kallar vi för de sovande gasellerna eftersom tidigare studier har visat att hög lönsamhet är en viktig faktor för en långsiktigt hållbar framtida tillväxt av antalet anställda. Andelen sovande gaseller inom detaljhandeln är cirka 1,5 till 2,35 procentenheter fler än i ekonomin som helhet. Hälften av dessa detaljhandelsföretag kommer inte heller att öka antalet anställda i kommande perioder, trots att de fortsätter att ha en hög lönsamhet eller en lönsamhet i paritet med det genomsnittliga företaget. Detta visar att det finns en dold tillväxtpotential inom detaljhandeln i Sverige som inte har realiserat. Resultaten från studien visar också att de sovande gasellerna inom detaljhandeln inte är slumpmässigt dragna ur företagspopulationen, utan att det framförallt är små företag som väljer att inte expandera verksamheten mellan två treårsperioder. De sovande gasellerna är inte heller slumpmässigt fördelade geografiskt i Sverige. De kommuner som har en hög andel sovande gaseller inom detaljhandeln under en tidsperiod tenderar att även ha det i kommande tidsperioder, vilket indikerar att det finns geografiska förklaringar till varför vissa företag inte växer trots att de har en god lönsamhet. Avsaknaden av tillväxt hos dessa företag kan antingen förklaras av att de inte har några tillväxtambitioner, oavsett villkoren för företagande; alternativt att de vill växa, men inte under rådande förutsättningar. Om den senare förklaringen är giltig kan reformer som minskar tillväxtbarriärer för detaljhandelsföretagen generera många nya arbetstillfällen.

Manlig utsatthet för våld i nära relationer : En kvalitativ studie om socialsekreterares arbete med män som utsätts för våld i nära relationer

Syftet med denna studie är att undersöka om socialarbetare tillämpar genusmedvetenhet i arbetet med personer som är utsatta för våld i nära relationer, och hur det i så fall uttrycker sig i mötet med dessa klienter. För att besvara dessa frågeställningar har en kvalitativ ansats tillämpats, med vinjettintervjuer som metod. Den hypotetiske klienten var för tre av informanterna en våldsutsatt man och för tre informanter en våldsutsatt kvinna. Informanternas svar jämfördes sedan och analyserades med hjälp av tidigare forskning på området samt teorier om genus, stereotyper och institutionalisering. De slutsatser vi kunnat dra genom denna studie är att socialarbetare till viss mån påverkas av könsstereotypa föreställningar och att man gör skillnad mellan könen vad gäller insatser, bedömningar och bemötande. Dock har vi även sett att det alltid finns en vilja att hjälpa klienten om behovet finns, i den mån det är möjligt utifrån bland annat det politiska och ekonomiska läget.

Sleeping gazelles : High profits but no growth

Among 104,231 limited liability firms in Sweden with at least two employees during 1997- 2010, almost 10% did not hire new employees in any given 3-year period despite having high profits. Nearly half of these firms continued to have high or medium profits in the next threeyear period, but still no growth. Regression analysis indicates that these firms were not randomly distributed; rather they were small and young, did not belong to an enterprise group, and operated in local markets with high profit-opportunities. We conclude that it might be more beneficial to focus policy towards these firms instead of towards a few high-growth firms that, having just grown exponentially, may not be best positioned to grow further.
