The multilevel ordinal logistic mixed-effects method applied is proposed as a support tool to management in basketball teams helping to identify the game-related statistics that discriminate the final ranking in a regu-lar season classification. A sample of 10684 games that cover 10 seasons and reach sample of 752 cases were evaluated from the two main Spanish basketball lea-gues (male and female). The multilevel analysis applied identifies the marginal effects of the main variables regularly evaluated by coaches and managers in bas-ketball leagues, which may help them improve the per-formance of their teams. The results revealed that in Re-legation zone the marginal contribution of field shots, defensive rebound, steals and turnovers percentage are 8.3 percentage points (pp), 7 pp, 9.6 pp and 8.6 pp res-pectively, higher than in Play-off zone (p

The intention of this research is to solve the statistical difficulty when statistical economic series are spliced. Therefore, this paper discusses the scope of the various methods of splicing in the literature. Also presents an additional method, which considers a process of maximization for structural interpolation. Since Venezuela does not escape the problem of the statistical joints in on accounts, this work also presents a complete series of Gross Domestic Product by productive economic activity and by expenditure components, from 1950 until 2005, expressed in base year prices 1997.

This paper delves into the asymmetries of the exchange rate pass-through on prices in the case of Venezuela, extending the analysis of Mendoza (2004) the prices of goods and services. The data used is monthly for the period 07/90 -12/04. We find that pass-through in services is less than pass-through in goods. This result may reflect the presence of a major component of non-tradables in the former than the latter. For both groups there is evidence of price asymmetries associated mainly to the behavior of oil prices, the misalignment of the real exchange rate and monetary expansions or contractions.

Esta investigación presenta una propuesta para medir el indicador de presión del mercado cambiario para el caso de Venezuela, haciendo uso de análisis de componentes principales. Por su parte, se presenta un modelo monetario ampliado con la riqueza del sector no financiero y la dinámica entre las tasas de interés domésticas y foráneas, para contrastar empíricamente, a través de método econométrico de retardos distribuidos, los determinantes de la presión del mercado cambiario venezolano dentro de la dinámica de la política monetaria en Venezuela entre los años 1984 y 2003.

We try to establish which is the structure that best defines the venezuelan foreign exchange market. Asking ourselves whether there exist a group of agents able to exert market power. We assume that the flow of currency between banks follows a first order stochastic Markov process of first order, in which competition is understood as a dynamic process of rivalry for trading the largest volume of currency under free convertibility. We use daily aggregate currency flows across banks to estimate probabilities of transition, which can be interpreted as approximations to the degree of rivalry between banks. In addition competition for currencies transactions was studied in a dynamic way.
