The risk return relationship is analysed in bivariate models for return and realised variance (RV) series. Based on daily time series from 21 international market indices for more than 13 years (January 2000 to February 2013), the empirical findings support the arguments of risk return tradeoff,...

While the risk return trade-off theory suggests a positive relationship between the expected return and the conditional volatility, the volatility feedback theory implies a channel that allows the conditional volatility to negatively affect the expected return. We examine the effects of the risk...

This paper provides new evidence on the risk return relationship by jointly analysing index return and realised variance (RV) series. It is argued that the contemporaneous correlation (CC) between the return and RV, which has been largely overlooked in the literature, is a crucial component in...

A growth model, in which economic growth is driven by R&D activities, is constructed to analyse issues related to the riskiness of R&D. It is shown that when R&D are risky strongly-risk-averse behaviour may suffocate the potential growth of a closed economy if risk-sharing arrangements are...
