Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...

This paper examines the relationship between the level of democratization and stock index returns in a sample of 74 countries. Compared with democracies, autocratic states are characterized by lower returns despite exhibiting higher return volatility. Even though this higher volatility can be...

Firm size is an essential factor in examining the relation between returns and idiosyncratic volatilities. This paper documents that, when the idiosyncratic volatility is specified by firm size, the size-portfolio idiosyncratic volatility is statistically significant in explaining the future...

This paper estimates economic returns to physical capital and inherent ability among Indonesian fishermen using a natural experiment. By exploiting the quasi-random variation in the length of fishing boats generated by an aid program among survivors of the 2004 Indian Ocean tsunami, it is found...

Our paper studies the impacts of the Dieselgate scandal on the required rate of return on equity investments into VW, Daimler, and BMW. The object of investigation is the beta coefficient that determines the risk premium in the Capital Asset Pricing Model (CAPM). Our research takes a deep dive...
