This paper estimates the causal e ect of perceived job insecurity - i.e. the fear of involuntary job loss - on health in a sample of 22 European countries. We rely on an original instrumental variable approach based on the idea that workers perceive greater job security in countries where...

This article uses graph theory to provide novel evidence regarding market integration, a favorable condition for systemic risk to appear in. Relying on daily futures returns covering a 12-year period, we examine cross- and intermarket linkages, both within the commodity complex and between...

To assess how financial markets and commodities are inter-related, this paper introduces a ‘volatility surprise’ component into the asymmetric DCC with one exogenous variable (ADCCX) framework. We develop an econometric model in which returns and volatility allow to influence pairs of...

The study of tail events has become a central preoccupation for academics, investors and policy makers, given the recent financial turmoil. However, the question on what differentiates a crash from a tail event remains unsolved. This article elaborates a new definition of stock market crash...

The mispricing of the deep-in-the money and deep-out-the-money generated by the Black and Scholes model is now well documented in the literature. In this paper, we discuss different option valuation models on the basis of empirical tests carry out on the French option market. We examine methods...

This article brings new insights on the role played by (implied) volatility on the WTI crude oil spot price. An increase in the volatility subsequent to an increase in the oil price (i.e. inverse leverage effect) remains the dominant effect as it might reflect the fear of oil consumers to face...

This article inves tigates the time evolution of the integra tion of derivative markets through the graph-theory. We focus on three categor ies of underlying as sets : energy and agricultural products , as well as financial assets . Integration is seen as a necessary condition for systemic risk...

In this paper, we are dealing with financial high frequency data; any time an order reaches the market, any time a cancellation or transaction occurs, a new record is made, ending up with a huge amount of data. Hence the time interval between two events is not fixed, forbidding the use of...

The lack of success of past strategies in reducing poverty has raised doubts as to whether these strategies were really an appropriate response to the needs of impoverished populations. Bearing in mind the aims of the new generation of development programmes to "empower" the poor, representative...
