Cross-ownership as a structural explanation for over- and underestimation of default probability

Based on the work of Suzuki, we consider a generalization of Merton’s asset valuation approach in which two firms are linked by cross-ownership of equity and liabilities. Suzuki’s results then provide no arbitrage prices of firm values, which are derivatives of exogenous asset values. In contrast to the Merton model, the assumption of lognormally distributed assets does not result in lognormally distributed firm values, which also affects the corresponding probabilities of default. In a simulation study we see that, depending on the type of cross-ownership, the lognormal model can lead to both over- and underestimation of the actual probability of default of a firm under cross-ownership. In the limit, i.e. if the levels of cross-ownership tend to their maximum possible value, these findings can be shown theoretically as well. Furthermore, we consider the default probability of a firm in general, i.e. without a distributional assumption, and show that the lognormal model is often able to yield only a limited range of probabilities of default, while the actual probabilities may take any value between 0 and 1.     

Comparison of Mean-Risk Efficient Portfolios in Asia-Pacific Capital Markets

In order to analyze the performance of mean-risk efficient portfolios, several methods of portfolio comparison have been developed. In this paper we analyze the second-order stochastic dominance efficiency of portfolios on the mean-risk efficient frontier assuming that the risk is represented by standard deviations and concordance matrices set up on the basis of Pearson's linear correlation, Spearman's rho, or Kendall's tau. Empirical analysis of the market returns of selected Asia-Pacific stock markets is carried out considering both the U.S. dollar and euro as reference currencies, and different periods: before and during the subprime crisis. Measures and portfolios on the mean-risk efficiency frontier that should be of interest to at least one risk-averse investor are empirically documented.     

Evidence on the purchasing power parity in a panel of cities

Evidence is provided on the PPP hypothesis using a sample of 50 Spanish cities for a long time period through the application of panel data unit root tests. Although results suggest non-rejection of the PPP, short-run deviations – as measured by half-lives – indicate that real factors might be causing a slow rate of convergence to a common price index, even in highly integrated economies.     

Evaluating the Impact of Educational Expansion on the Occupational Status of Youth

This paper exploits the remarkable increase in the average educational attainment of Australian youth during the 1980's to evaluate the role of education in labour market performance. Rather than focus on the impact of schooling on wages, however, we examine changes in the occupational distribution of recent labour market entrants. The evidence indicates that the educational expansion appears to move all individuals up the educational ladder without altering their relative position. The results indicate that while the second cohort obtained substantially more education than the first cohort the occupational distribution of the two cohorts were almost identical. Furthermore, there was no evidence that the increased education counterbalanced changes in the structure of labour demand or manifested itself in higher wages.     

The management perception of the strategic outsourcing of services: An empirical examination in the hotel sector

This work will analyse the strategy of outsourcing, or the predisposition on the part of a firm to entrust some of its services to a third party. The research will focus on discovering empirically the role that this strategy plays in hotels, and in order to do this we will carry out an analysis of hotel managers' perceptions regarding outsourcing based on the main advantages as well as the drawbacks and barriers which using the strategy can involve, with a view to determining which of these are related to a predisposition to outsource. The results of the research suggest that the main reasons which determine outsourcing are of a strategic rather that cost-reducing nature. Despite the fact that although current outsourcing is conditioned by the cost factor alone, any future increase in the use of the strategy will be determined exclusively by factors of a strategic nature. With respect to the disadvantages of outsourcing which tend to limit the use of the strategy, we will see that these are related to loss of control and autonomy together with a distrust of external suppliers. This work will enable us to assess the extent of the existing demand for outsourcing main services as well as those factors which determine and limit the outsourcing strategy and which have prevented a large number of services where outsourcing would be applicable from being outsourced to the present date. Finally we will present our main conclusions and recommendations.     

Institutional design and governance of airport regulators: The case of Latin America

This paper offers a cross-country assessment of the governance of airport regulators in Latin America. The analysis links the institutional design of airport regulators, whether in the form of independent regulatory agencies or government departments, to their overall governance. It examines four dimensions of regulatory governance: autonomy, transparency, accountability, and bureaucratic quality. Independent regulatory agencies in the Latin American airport sector seem to provide a better framework for transparency and bureaucratic quality than government departments. It is not conclusively found, however, that independent regulatory agencies contribute to a more autonomous decision-making or to an enhanced accountability of regulators to other branches of government and airport users. Overall, governance indicators of airport regulators in Latin America are well below the threshold that defines good governance.
