This paper analyzes the impacts of timing errors, capital flows and economic openness on the behavior of the balancing item. We choose Norway, Sweden, Philippines and South Africa as sample countries where the size of the balancing item is often excess the IMF's criterion of ‘smallness'. The empirical results show that the sources of the volatility of the balancing item are different among these four countries.Balancing item, Balance of payments
The strong decays of charm-strange baryons up to N=2 shell are studied in a
chiral quark model. The theoretical predictions for the well determined
charm-strange baryons, Ξc∗(2645), Ξc(2790) and Ξc(2815), are in
good agreement with the experimental data. This model is also extended to
analyze the strong decays of the other newly observed charm-strange baryons
Ξc(2930), Ξc(2980), Ξc(3055), Ξc(3080) and Ξc(3123).
Our predictions are given as follows. (i) Ξc(2930) might be the first
P-wave excitation of Ξc′ with JP=1/2−, favors the $|\Xi_c'\
