In this paper we investigate whether the empirical regularities of stock returns are independent of each other or whether any one of them implies all the others. If such a regularity exists, it is called 'fundamental' and is usually thought of as a 'deductive explanation' of the others. We...

A model is introduced for the description of natural resources price paths, which, in contrast to the existing literature, captures non-linear trends by means of a simple trigonometric function. This model is then compared by means of a set of model selection criteria with a quadratic trend...

In this paper a Methodology for Integrated Socio-Economic Assessment (MISEA) of the viability and sustainability of different designs of Multi-Use Offshore Platforms (MUOPs) is presented. MUOPs are designed for multi-use of ocean space for energy extraction (wind power production and wave...

While the financial world is experiencing a crisis, the prices of most agricultural commodities have remained high, although exhibiting extreme volatilidy. Motivated by evidence showing that volatility trends are present in agricultural commodity prices, we analyze stochastic processes whose...

This paper aims at identifying the motivating forces that gave birth to the statistical models of asset returns since the beginning of the twentieth century. The major question addressed is: Where do statistical models of asset returns come from?" This central question encompasses a number of...

In this paper we examine whether the real prices of eleven natural resource commodities exhibit stochastic or deterministic trends. A common methodological feature in the relevant empirical literature, most of which published in the Journal of Environmental Economics and Management, has been so...

Statistical models are usually thought of as means for describing statistical regularities. Concerning stock returns, many empirical regularities have been documented in the literature together with their corresponding models. The main task of this paper is to investigate, under the prism of the...
