- Abstract
- This paper develops a new methodology for simulating fixed-income return distributions. It is shown that a traditional factor risk model, when augmented with reference returns, is capable of generating visually consistent return distributions for a broad range of fixed income instruments such as government and nongovernment instruments in the US dollar and Japanese yen bond markets. The reference returns result from a regime-switching Nelson-Siegel yield curve model following Bernadell, Coche and Nyholm (2005). Empirical results are encouraging: simulated distributions exhibit most characteristics observed in the fixed income markets such as non-normal right-skewed distributions for short maturity instrument while instruments with longer maturity are closer to being normally distributed.

- Abstract
- This paper studies the implications of introducing an explicit policy objective to the management of foreign reserves at a central bank. A dynamic model is developed which links together reserves management and the exchange rate by foreign exchange interventions. The exchange rate is modelled as a mean-reverting autoregressive process incorporating a linear response to interventions. The premise is that it is the objective of the central bank to prevent undervaluation of its currency. Given this objective, the model is formulated in a one- and a multi-period setting and solved to find the optimal asset allocation. The results show that asset allocation can significantly help in achieving the desired policy objective.

- Abstract
- This paper presents a new framework allowing strategic investors to generate yield curve projections contingent on expectations about future macroeconomic scenarios. By consistently linking the shape and location of yield curves to the state of the economy our method generates predictions for the full yield-curve distribution under different assumptions on the future state of the economy. On the technical side, our model represents a regimeswitching expansion of Diebold and Li (2003) and hence rests on the Nelson-Siegel functional form set in state-space form. We allow transition probabilities in the regimeswitching set-up to depend on observed macroeconomic variables and thus create a link between the macro economy and the shape and location of yield curves and their time-series evolution. The model is successfully applied to US yield curve data covering the period from 1953 to 2004 and encouraging out-of-sample results are obtained, in particular at forecasting horizons longer than 24 months.
