We propose two nonparametric transition density-based speciÞcation tests for continuous-time diffusion models. In contrast to marginal density as used in the literature, transition density can capture the full dynamics of a diffusion process, and in particular, can distinguish processes with...

We show why considering a number of education-dependent covariates in the wage equation decreases coefficient of education in the wage equation. We use a meta-analysis of results for Portugal to show, empirically, that this is the case. The coefficient decreases when we use covariates that can...

The paper uses quarterly GDP data for some 30 years up to and including 2001, to examine the identity and development of the European business cycle. Cycles are identified by using a band-pass filter version of the Hodrick-Prescott filter and affiliations are examined using clustering techniques...

We apply different matched-pair methods to evaluate the policy of sustaining the adoption of advanced manufacturing technologies by Swiss firms and we compare it in decomposing the selection bias. In this aim we present the evaluation problem, the decomposition of the selection bias and the...

This study presents an alternative way of estimating credit transition matrices using a hazard function model. The model is useful both for testing the validity of the Markovian assumption, frequently made in credit rating applications, and also for estimating transition matrices conditioning on...

This paper is a substantially revised version of our earlier working paper, "Truth and Robustness in Cross-country Growth Regressions." The most important revisions concern the handling of missing observations in the cross-country data set. In the earlier paper, these had been handled through...

Contemporary actuarial and accounting practices (APN 110 in the South African context) require the use of market-consistent models for the valuation of embedded investment derivatives. These models have to be calibrated with accurate and up-to-date market data. Arguably, the most important...

Market leverage is one of the main determinants for defining the optimal capital structure of the firm, and has a significant impact on several variables that affect the design of the firm's business strategy. This paper is focussed on the potential methodologies exploitable to obtain reliable...

This study investigates the correlation between exports and imports in the case of Pakistan by using the variance decomposing analysis and rolling window bound testing approach to determine the stability of cointegration over the sample. The results from variance decomposition indicate that...
