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...

In recent years, wavelets have become widely used in physics, engineering, and mathematics. They have been used for signal processing, image processing, numerical computation, and data compression. Wavelets have not, however, been used very much in the fields of Economics, Econometrics, and...

We present several Markov chain Monte Carlo simulation methods that have been widely used in recent years in econometrics and statistics. Among these is the Gibbs sampler, which has been of particular interest to econometricians. Although the paper summarizes some of the relevant theoretical...

The essential idea of equilibrium search models of labour market behaviour is that wage policy matters. In contrast, the stylized neoclassical competitive model predicts that firms paying a wage above the competitive equilibrium will disappear; those offering less will attract no workers. The...

We have collected data on the one-year-ahead income expectations of members of American households in our Survey of Economic Expectations (SEE), a module of a national continuous telephone survey conducted at the University of Wisconsin. The income- expectations questions take this form: "What...

The authors examine the issue of lag-length selection in the context of a structural vector autoregression (VAR) and a vector error-correction model with long-run restrictions. First, they show that imposing long- run restrictions implies, in general, a moving-average (MA) component in the...

The notion that lack of knowledge undermines the economic performance of African countries is deeply and widely held to be true. Yet evidence for the basis of that truth is few and far in-between. This paper first describes a production function approach to the creation of knowledge of African...
