This paper considers the size effect, where volatility dynamics are dependant upon the current level of volatility within an stochastic volatility framework. A non-linear filtering algorithm is proposed where the dynamics of the latent variable is conditioned on its current level. This allows...

Farmers\' exposure to pesticides is high in developing countries. As a result they suffer from ill-health, both short and long term. Deaths are not uncommon. The paper examines the cause of this high exposure by estimating farmers’ expenditure on precautions taken using the avertive behaviour...

In this paper, we propose to study the synthesis of Gegenbauer processes using the wavelet packets transform. In order to simulate 1-factor Gegenbauer process, we introduce an original algorithm, inspired by the one proposed by Coifman and Wickerhauser [CW92], to adaptively search for the...

This paper is concerned with some corporate governance issues related to newly listed firms in China based on a sample of 329 firms commencing listing on Shanghai Stock Exchange (SHSE) and Shenzhen Stock exchange (SZSE) during the period from 1998 to 2000. We first investigate the impact of...

In this study, productivity growth in thirty-five Australian universities is investigated using nonparametric frontier techniques over the period 1998 to 2003. The inputs included in the analysis are full-time equivalent academic and non-academic staff, non-labour expenditure and undergraduate...

In the business cycle literature researchers often want to determine the extent to which models of the business cycle reproduce broad characteristics of the real world business cycle they purport to represent. Of considerable interest is whether a model’s implied cycle chronology is consistent...

Conservation of biodiversity is a complex issue. Apart from the creation of nature reserves, there is a plethora of other factors that are part of this complex web. One such factor is the public knowledge of species. Since public funding is imperative for the conservation of species and creation...

We propose an endogenous growth model that incorporates the importance of business contacts and informal contacts. In our model, sold output increases with the stock of business contacts. The modelling of contact creation is based on matching theory. The cost of creating contacts decreases with...

This paper examines the welfare costs of inflation within a monetary dynamic general equilibrium framework with human capital that incorporates endogenous, ex ante skill heterogeneity among workers. Numerical experiments indicate that, overall, welfare costs are more likely to decrease with...

The paper demonstrates the drawbacks on using official data and binary indices when attempting an interstate comparison of output and productivity growth. The use of official data in one’s national currency still requires a numerary currency due to price variations across states. Even with the...
