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 order to reduce the finite sample bias and improve the rate of convergence, local polynomial estimators have been introduced into the econometric literature to estimate the regression discontinuity model. In this paper, we show that, when the degree of smoothness is known, the local...

We review Hildreth's algorithm for computing the least squares regression subject to inequality constraints and Dykstra's generalization. We provide a geometric proof of convergence and several enhancements to the algorithm and generalize the application of the algorithm from convex cones to...

This paper is a user's guide to a set of Gauss procedures developed at the Bank of Canada for estimating regime-switching models. The procedures can estimate relatively quickly a wide variety of switching models and so should prove useful to the applied researcher. Sample program listings are...

This paper explores two very different models which might account for stock market crashes. A key innovative feature of our paper is that we use the models to show how their implications for stock market crashes may be tested using switching-regression econometrics. We are careful to show that...
