DUCROIRE: Politic risqs very low Trade risks: Moderately high (B on a scale from A to C) Payment conditions : The political and economic situation in Australia is therefore very good. Payment behavior of companies is very reassuring, with a low probability of default. Main French investments in Australia (Firms) : The Australian firms’ presence in France is still weak. Among the very few Australian investors in France, we find: 1. ERG ( cartes à puce). 2. Billabong (sportswear) 3. BHPbiliton

the derived Treasury spot rates. The estimated values seem are consistent with previous findings as well as with financial theory. The spreads increase in magnitude as we move down the credit ratings, indicating, ceteris paribus, a higher default probability for lower grade bonds. Of interest as well is that, except for AAA spreads, the slope of the credit spreads increases with maturity. This term premium increases monotonically as credit quality decreases. We now select the variables to represent

philosophical commitments can be of use in explaining why Frank Knight closes down the distribution controversy, proposing instead a reconstruction of economics as a rational choice science.

The probability is expressed as a value ranging from zero to 1. ex post Means after the event. An ex post budget, or standard, is set after the end of a period of activity, when it can represent the optimum achievable level of performance

exports is the largest single influence on the risk of conflict and the effect is non-linear. These authors also argue, for instance, that a country with no natural resources has a probability of civil conflict of 0.5 percent, but that a country with a share of natural resources in GDP of 25 percent has a probability of civil conflict of 23 percent. The presence of a centrally controlled pool of wealth also encourages unproductive rent-seeking behavior in other sectors of the economy. Natural resource

dispensed with and the validity of a more general proposition on the irrelevance of financial structure, within a general equilibrium context, could easily be established, provided only that firms do not issue so much debt that they incur a positive probability of bankruptcy (Stiglitz, 1969). The restated theorem asserted simply that, if there is an equilibrium with a firm having a particular debt-equity ratio and market value, there exists another equilibrium with the firm having any other debt-equity
