Cosmological and astrophysical limits on brane fluctuations

We consider a general brane-world model parametrized by the brane tension scale $f$ and the branon mass $M$. For low tension compared to the fundamental gravitational scale, we calculate the relic branon abundance and its contribution to the cosmological dark matter. We compare this result with the current observational limits on the total and hot dark matter energy densities and derive the corresponding bounds on $f$ and $M$. Using the nucleosynthesis bounds on the number of relativistic species, we also set a limit on the number of light branons in terms of the brane tension. Finally, we estimate the bounds coming from the energy loss rate in supernovae explosions due to massive branon emission.Comment: 26 pages, 6 figures, LaTeX. Final version with minor corrections.

An econometric model of the monetary sector in Indonesia

Aims to develop an econometric model of the Indonesian monetary sector over the period, 1969-80. Before such a model was constructed, the hypothesis that there is a causal relationship between money supply and the aggregate price index was tested, using quarterly data. The hypothesis of a causal relationship from prices to money was supported while the hypothesis of contemporaneous causality could not be easily dismissed. In the model, both money supply and the aggregate price index were used as endogenous variables and they were decomposed into several disaggregates. The possibility of a structural break after the oil price shock (post-1973) was examined using forecasting criteria. The predictive performance for 1969-73 is better than for 1974-80.-Author
