While numerous empirical papers have investigated the volatility dynamics of Chinese clean energy equity markets, this is among the first studies to assess the impact of climate uncertainty on the risk levels of such assets. Given that China is extensively investing in green projects to achieve carbon neutrality, this strand of research offers important implications for investors and policymakers. Methodologically, we employ the GARCH-MIDAS model to examine the effect of the climate policy uncertainty (CPU) index on the volatility levels of the Chinese clean energy exchange-traded fund (ETF). We compare the effects of the CPU index with leading uncertainty indicators, including the crude oil volatility index, geopolitical risk, and technology sector volatility. The in-sample and out-of-sample analyses show that CPU has significant predictive contents for forecasting the volatility of renewable energy ETF and that the GARCH-MIDAS-CPU process outperforms other approaches. These results offer key implications for policymakers and socially responsible investors.

Inequality: Economic and Social Issues.

Sammanfattning

In ‘Discrimination as a Determinant of Economic Inequality’, Ali Ahmed, Mats Lundahl, and Eskil Wadensjö examine how economic theory can be used to unearth the mechanisms to produce discrimination and inequality, to identify the winners and losers from it, and to construct recipes for the eradication of discrimination. They stress the fact that economics is far from a unified social science and hence the need to apply different theories as different situations call for it. Two notorious cases are examined: the South African apartheid system and the American discrimination of blacks by whites. The chapter ends with an examination of a number of contemporary cases of ethnic discrimination of minorities.

Sammanfattning

Employment is vital for the quality of life and societal integration of disabled people, who often encounter barriers. Programs like Sweden’s state-owned company Samhall are designed to level the playing field. Yet, whether discrimination persists after program participation and ample work experience remains an intriguing question. We investigated whether signaling disability through work experience at Samhall affects employability in Sweden for cleaning roles. A field experiment was conducted in which 768 fictitious job applications were sent to employers with vacant cleaner positions in Sweden. Implied disability, indicated by work experience at Samhall, and gender were randomly varied in the applications. The primary outcome metric was positive employer responses. Disabled applicants received fewer positive responses (28%) than non-disabled applicants (34%). Discrimination was more pronounced for disabled male applicants. The study reveals nuanced discrimination against job applicants with disabilities in Sweden, particularly disabled males, despite their extensive training and experience.

Sammanfattning

This paper presents the first study to investigate ethnic differential treatment in public housing through a correspondence test field experiment. The experiment involved sending inquiries from fictitious couples with Swedish or Arabic names to all public housing companies in Sweden. Four outcomes were examined: whether the public housing companies responded to the inquiries, whether they initiated their response with a greeting, whether they had a priority system in place, and whether they provided information about problematic neighborhoods. The findings revealed disparities in the treatment of the couples. The Swedish couple received greetings and information about problematic neighborhoods at a greater rate than the Arab couple. This study contributes to existing literature on ethnic differences in the housing market by providing evidence of differential treatment within the public housing sector. Additionally, it explores the content and quality of public housing companies’ responses, offering valuable insights for policymakers and housing professionals in designing interventions to promote equality and counteract differential treatment.
