It is assumed that performance of production system can be described with the three variables: amount of production equipment -- capital stock $K$ and 'consumption' of labour L and capital services S. It is shown that the production function can be specified as the known Cobb- Douglas production...

In this paper we address the issue of modeling spot electricity prices. After analyzing factors leading to the unobservable in other financial or commodity markets price dynamics we propose a mean reverting jump diffusion model. We fit the model to data from the Nord Pool power exchange and find...

For many economic problems standard statistical analysis, based on the notion of stationarity, is not adequate. These include modeling seasonal decisions of consumers, forecasting business cycles and - as we show in the present article - modeling wholesale power market prices. We apply standard...

A reduction of trade barriers will influence the overall scale of agricultural activities, the structure of agricultural production in different countries, the mix of inputs and outputs, the production technology, and the regulatory framework. These adjustments, in turn, will impact on the...

The interest rate and the rate of economic growth are often regarded as roughly constant as economies grow. Moreover, the agricultural sector and rural population typically shrink. We show that an otherwise standard growth model that includes a backward and an advanced sector can account for...

We consider processes with second order long range dependence resulting from heavy tailed durations. We refer to this phenomenon as duration- driven long range dependence (DDLRD), as opposed to the more widely studied linear long range dependence based on fractional differencing of an $iid$...

The aim of this paper is to provide evidence about the existence or non- existence of structural breaks in exchange rates of European transition economies. We used the testing procedure of Vogelsang (1997) that allows for detecting a break at an unknown date in the trend function of a dynamic...

Since 1970 nearly all-Mediterranean countries of the EC had undertaken measures to regulate their domestic market for ordinary wines, in the context of constant fall in domestic demand for that product. This paper provides an empirical modelling framework for understanding the effect on the...
