national currency depreciation or appreciation has always been argued seriously among policymakers since changing in exchange rate could cause improvement or deficit in trade balance. these changes affect the trade volume of a country in both short-run and long-run. long-run effects are recognized as the marshall-lerner condition, while short-run effects are analyzed by two concepts: j-curve an...

Using a vector error-correction model, I explore the short-run dynamics and long-run linkages between financial reform and the mobilization of domestic saving in Morocco. In the short run, financial depth (volume of intermediation) is shown to have a positive influence on private saving, while increases in real interest rates have a negative impact. The effectiveness of financial intermediation...

High jumpers run at moderate speeds and set down the foot, from which they take off, well in front of the body. Long jumpers run up much faster and place the foot less far forward, with the leg at a steeper angle. A simple model, which takes into account the mechanical properties of muscle, predicts optimum take-off techniques that agree well with those used by athletes. These predictions are r...

The claims reserves analysis is performed using a Tweedie distribution. Since the aggregate cost per cell of a run-off triangle is generated by a compound distribution, we show that modelling of the variance is important. Dispersion modelling, as well as double GLM theory are not only used to predict the total amount of reserves, but also the mean square error of prediction of the reserves. A n...
