This paper looks at the history of money and its modern form from a scientific and mathematical point of view. The approach here is to emphasize simplicity. A straightforward model and algebraic formula for a large economy analogous to the ideal gas law of thermodynamics is proposed. It may be...

The aim of this paper is the realization of a Benchmark analysis about the relative position of the Valencian Innovation System. This comparison has been threefold comparing the Spanish, Mediterranean and European regions. In order to undertake this analysis, on the one hand, for the Spanish...

With around 50% of the urban men between age 15 and 30 unemployed, Ethiopia has one of the highest unemployment rates worldwide. This paper describes the nature of unemployment among young men in urban Ethiopia. We analyse the determinants of incidence and duration and find that most variables...

This paper analyzes the effects of anticipated inflation on the resource allocations between production and financial services. We develop a model with heterogeneous workers and two sectors economy. A manufacturing sector producing a final composite good and a financial sector providing monetary...

Analysis of road fereight transport is hindered by the lack of diecdirect observartions of the handling factor. The handling factor is the frequency of lifts of the tonnes in the supply chain from origin to destination. It is also the number of times that the same tonnes are reported to the...

We consider the situation when there is a large number of series, $N$, each with $T$ observations, and each series has some predictive ability for the variable of interest, $y$. A methodology of growing interest is to first estimate common factors from the panel of data by the method of...

We examine the ability of the simple linear-quadratic model under rational expectations to explain dynamic behaviour of aggregate Canadian imports. In contrast to authors of previous studies who examine dynamic behaviour using the LQ model, we estimate the structural parameters using the Euler...

Accurate estimation of the dominant root of a stationary but persistent time series are required to determine the speed at which economic time series, such as real exchange rates or interest rates, adjust towards their mean values. In practice, accuracy is hampered by downward small- sample...

An econometric methodology is developed for nonparametric estimation of concave production technologies. The methodology, bases on the priciple of maximum likelihood, uses entropic distance and concvex programming techniques to estimate production functions.

El presente trabajo plantea un modelo estadístico flexible que captura paramétricamente la compleja condicionalidad y desvíos de normalidad que caracteriza a la estructura intertemporal de tasas de interés en la economía chilena entre los años 1992 y 2003. El modelo general consiste en una...
