Case1: Exchange Rate Projections. Casullo Financial Services (CFS). Zhen Qi

Outline  Purpose of this Case  Models used for this Case Study  Test the forecasting skills of the models for USD to GBP, JPY, MXN, and KOW  Out-of-sample forecasts of the Models for USD to GBP, JPY, MXN, and KOW  Select the "best" model  Project the exchange rate for the GBP and JPY through 2012:2 using the best Model

Purpose of this Case  Select the "best" model among (A) Forward exchange rates. (B) Ad-hoc economic models. (c) PPP. (D) Monetary approach.  Forecasting Exchange rate for USD to GBP, JPY, MXN, and KOW (Korean Won) for the time period 2011:3~2012:2

Models used for Case Study 1. Forward exchange rates, Linear IRP approximation: F t,T  S t [1 + (i d - i f ) x T/360], 2. Ad-hoc economic model S d/f,t = a 0 + a 1 (I d – I f ) t + a 2 (y d – y f ) t + ε t 3. Relative PPP simplified Model s t,T  e f,T PPP  I d – I f 4. Monetary approach s t,T = y f,T - y d,T + m Sd,T - m Sf,T

Test the forecasting skills  The forecasting skills of these 4 models were tested based on the information available at the end of 2010:2.  The in-sample performance of the models were evaluated by evaluating the signs, the t-statistics, and the R-squared coefficients.  The above tasked were tested using the data available for the USD/GBP, USD/JPY, USD/MXN, and USD/KOW
