This paper aims to explore which macroeconomic factors affect the volatility of the automakers stock prices by employing a multifactor model. The study uses quarterly panel data of 39 automakers quoted on the stock exchanges in the 11 countries. It studies the effects of 19 macroeconomic variables from January 2000 to December 2017, and proposes the mixed-effect model constructed based on employing genetic algorithm and AIC criterion, and compares its explanatory power with the existing multifactor model (El Khoury, 2015 El Khoury, R. M. (2015). Do macroeconomic factors matter for stock returns? Evidence from the European automotive industry. International Journal of Monetary Economics and Finance, 8(1), 71–84. doi: 10.1504/IJMEF.2015.069170 [Crossref] , [Google Scholar] ). This paper suggests that the proposed model can shed more light on explaining the variability of stock prices of the quoted automakers. The findings show there are positive linkages between automaker's stock return volatility and explanatory variables such as stock market development, GDP and unemployment. Conversely, an inverse linkage between the dependent variable and money supply and IPI was found. The study demonstrates that selected macroeconomic factors can also be used as predictors.

This paper examines the effectiveness of implementing carbon taxes to reduce carbon dioxide emissions from transport. Using the system Generalized Method of Moments estimator, we utilize cross-country analysis for the first time to study the impact of carbon taxes on the composition of petrol versus diesel passenger cars sold in 17 countries over the period 2013–2017. The results suggest that increasing carbon taxes affects consumer behavior, causing a significant shift from petrol to diesel fuel vehicles, controlling for factors such as the price of passenger cars, fuel price, interest rates, income level, population density, inflation, and vehicle stock.

The climate crisis and rise in income inequality have created support for progressive taxes with a top marginal tax rate above 50%. Three strands of literature are discussed to show this trend: (1) climate change, (2) income inequality, and (3) taxing the wealthy. Thoughtful flaws are noted in the current paper, especially by giving special attention to growing call for a tax on the wealthy to pay for the fight against climate change and reduce income inequality.
