Abstract [en]

This paper reports the results of a study that investigates the causal interactions among the entities energy consumption, democracy, income, and CO2 emissions in Bangladesh. Bootstrapping causality and time–frequency domain causality methods were adopted to examine the causal co-movements between the variables, using data series for a period of more than four decades. Results show that time-scale behavior plays an important role. Democracy is an important factor for emissions and national income. The nexus of democracy and CO2 emission is bidirectional. The impact of democracy on CO2 is stronger than vice versa. This study provides new insights for policymakers: democratic practices play an important role in implementing climate change policies, at least in the case of Bangladesh.

Abstract [en]

We used an experiment to investigate whether people’s decisions over employment opportunities are affected by the ethnicity and sex of their potential future coworkers. University students (N = 1,406) were asked to state the lowest hourly wage rate at which they would be willing to accept a job on a campus food truck, where they would work alongside the food truck owner. The ethnicity and sex of the food truck owners were randomized across participants. Results showed no signs of coworker prejudice in terms of the probability of being interested in the job and reservation wage.

Abstract [en]

The purpose of the study presented in this paper was to evaluate the first-mover disadvantage hypothesis. Data from a Swedish television cooking game show was used to test the hypothesis. Each week four contestants on the game show take turns hosting each other at a dinner. Contestants rate each other’s performance and compete for a considerable cash prize. The contestant receiving the highest rating wins the cash prize at the end of the week. The results show that being the first contestant to host the dinner during a week remarkably reduced the chances of winning the cash prize in the end of that week. The results imply that being the first does not always pay off in some circumstances.

Abstract [sv]

Utrikes födda personer särbehandlas i den skriftliga kontakten med landets kommuner. Det visar vårt experiment, där en man med svenskklingande namn fick bättre bemötande och mer information än en man med arabiskt namn. Diskrimineringen kan ge konsekvenser i form av sämre möjligheter till förskoleplats, skriver nationalekonomerna Ali Ahmed och Mats Hammarstedt.

Abstract [en]

We examine causal relationships among the macroeconomic entities tourism and output dynamics in India, using the frequency–domain causality approach. Our results show that there is a bidirectional causality between openness and tourism as well as between output and tourism, at various frequency bands. Hence, this study suggests a multiplier effect of tourism on the Indian economy.

Abstract [en]

This paper presents the findings of a field experiment on hiring discrimination against ex-offenders in the Swedish labor market. Matched pairs of written job applications for fictitious male and female applicants with and without a past conviction of assault were sent to employers for nine different occupations. Results show that discrimination against ex-offenders exists, but the extent of it varies across occupations. The past conviction of assault was associated with 7–18 percentage point lower probability of receiving a positive employer response. Discrimination against ex-offenders was pronounced in female-dominated and high-skilled occupations. The magnitude of discrimination against ex-offenders did not vary by applicants’ sex.

Abstract [en]

We examine the causal relationship between economic growth and CO2 emissions in a panel of 24 European countries from 1980 to 2010. Using an analytical framework that considers pooled mean group estimations in a dynamic heterogeneous panel setting, we show that there is an inverted U-shaped relationship between CO2 emissions and economic growth in the long run and that there is no such relationship in the short run. In particular, we find that biomass energy is insignificantly linked to CO2 emission. However, technological innovation significantly facilitates reduction of CO2 emissions in the investigated countries. Altogether, our study implies that economic growth and environmental quality can be achieved simultaneously, which opens up new insights for policy-makers for sustainable economic development via implementation of renewable energy consumption through technological innovation.

Abstract [sv]

Diskriminering är ett avsevärt hinder på arbetsmarknaden, bostadsmarknaden och andra marknader för personer med utländsk bakgrund. I Sverige finns lagstiftning som förbjuder diskriminering och en myndighet som har tillsyn över problematiken. Men vad säger forskningen om etnisk diskriminering i Sverige? Denna översikt redogör för nationalekonomiska undersökningar som entydigt har funnit belägg för etnisk diskriminering. I ljuset av denna översikt förs en diskussion kring det vi känner till och det vi behöver känna till. Slutligen framförs förslag om hur arbetet mot etnisk diskriminering kan förbättras.
