The aim of this study was to analyze the nature of affective relationships between parents and children and to explore representational models in a sample of 111 children aged between 3 and 6, assessed using a projective measure. The results obtained confirm that, globally, security in the representation of attachment is higher with mothers. The figure of the father in the established hierarchy is secondary. The results also reveal a statistically significant relationship between children’s age and the attachment established with their fathers and mothers. The older the child, the greater the security manifested in their relations, and the younger the child, the greater the insecurity.
Given the striking effects of the recent financial turmoil, and the importance of value and growth portfolios for both local and international portfolio allocation, we investigate the effects of systemic jumps on the optimal portfolio investment strategies across value and growth equity portfolios. We find that the cost of ignoring systemic jumps is not substantial, unless the portfolio is highly levered and the average size amplitude of the jump is large enough. From the optimal asset allocation point of view, it seems more important the effects of few but relatively large jumps than highly frequent but small jumps. Indeed, the period in which the value premium is higher coincides with a period of few, but large and positive average size jumps for value stocks, and negative and very large average size jumps for growth stocks.
