Pair-copulas modeling in finance 总被引:1,自引:0,他引:1

This paper concerns itself with applications of pair-copulas in finance, and bridges the gap between theory and application.
We provide a broad view of the problem of modeling multivariate financial log-returns using pair-copulas, gathering together
for this purpose theoretical and computational results from the literature on canonical vines. From the practitioner’s viewpoint,
the paper shows the advantages of modeling through pair-copulas and makes clear that it is possible to implement this methodology
on a daily basis. All the necessary steps (model selection, estimation, validation, simulations, and applications) are discussed
at a level easily understood by all data analysts. 相似文献

This study analyzes the impact of the gender composition of political institutions on the political budget cycle (PBC) and on the size and structure of public expenditure. An instrumental variable approach is implemented to evaluate the influence of female politicians in municipal councils. The introduction of gender quotas for Italian municipalities is used as an exogenous variation in female participation in politics. The results show that: (i) fluctuations in local public spending are only slightly affected by the presence of a wider female representation; (ii) an increase in the number of elected women reduces the overall amount of public expenditure; (iii) this reduction involves fields typically affected by PBC (e.g., roads' maintenance) except those related to females' needs (e.g., kindergarten, primary education, and social care). 相似文献
