We study the effects of competition on loan rates and loan portfolio quality in microcredit markets using a new database from rating agencies, covering 379 for-profit and nonprofit microfinance institutions (MFIs) in 67 countries over 2002-2008. First, we find competitive pressures from...

In order to capture observed asymmetric dependence in international financial returns, we construct a multivariate regime-switching model of copulas. We model dependence with one Gaussian and one canonical vine copula regime. Canonical vines are constructed from bivariate conditional copulas and...

This paper introduces and evaluates new models for time series count data. The Autoregressive Conditional Poisson model (ACP) makes it possible to deal with issues of discreteness, overdispersion (variance greater than the mean) and serial correlation. A fully parametric approach is taken and a...

We investigate the informative property of quoting activity, measured by the frequency of price revisions, in the Euro/Dollar foreign exchange market. We use the multivariate double autoregressive conditional Poisson model, designed for time series of count data. We find that dealers' quoting...

We use a sample of banks from 24 European countries to investigate whether the adoption of the Basel II Capital Accord in 2008 affects the market valuation of discretionary loan loss provisions (DLLPs). Although Basel II lowers the incentives of internal ratings- based (IRB) banks to recognize...

We propose a new dynamic model for volatility and dependence in high dimensions, that allows for departures from the normal distribution, both in the marginals and in the dependence. The dependence is modeled with a dynamic canonical vine copula, which can be decomposed into a cascade of...
