We believe that any adjustment and updating process (AUP) should try to minimize the relative deviation of the new coefficients from the initial ones in a homogeneous way. This homogeneity would mean that the magnitude of this relative deviation is similar among the elements of each row or...

Some authors point to the analysis of enterprise cooperation, as a dynamic process, as a future line of research. Within this context and looking at second grade Andalusian oil cooperative movement, we analyse of there is a positive association between the degree of adherence to the cooperative...

Theoretical models of growth and trade suggest that patterns of international specialisation are inherently dynamic and evolve endogenously over time. Initial comparative advantaged are either reinforced or gradually unwound with the passage of time. This paper puts forward an empirical...

This paper studies irreversible investment decisions of a risl neutral regulated firm which has costs of production and of investment known with certainty and constant over time, but subject to uncertainty on exogenous shocks to demand. These shocks follow a geometric Brownian motion. No...

Let X1,...,Xn be observed random variables generated by a chaotic transformation Y such that Xt=Y(Xt-1,...,Xt-m0). We construct and study an estimate of m0 based on X1,...Xn, using the fact that m0 is a breaking point for the regularity of the distribution of (Xt-1,...Xt-m), m=1,2,.... We...

We develop in this paper simple geometrical methods to study local indeterminacy, bifurcations and stochastic (sunspot) equilibria near a steady state, in nonlinear two dimensional economic models. We present in particular a simple geometrical characterization of the support of stochastic...

This paper uses household survey panel data of 416 rural households to study livestock asset dynamics in the north-east of Ethiopia. The period under examination (1996-2003) was marked by severe environmental shocks, including a series of droughts. Using as point of departure the literature on...
