This paper uses daily capital flows to the Swedish bond market to analyse the relative information endowment of domestic and foreign investors. Using the standard framework of a noisy rational expectations equilibrium it is shown that foreign investors are, on average, better informed than...

The floating of a number of European currencies in 1992-93 created a new body of data on risk premia on floating exchange rates. In this paper, excess returns to investments in SEK, NOK, FIM, GBP, ITL and EPT against the DEM are investigated. We model the risk premia as functions of time varying...

This paper is concerned with modelling time series by single hidden-layer feedforward neural network models. A coherent modelling strategy based on statistical inference is presented. Variable selection is carried out using existing techniques. The problem of selecting the number of hidden units...

In this paper, which is a substantial extension of the earlier essay Björk (2001), we give an overview of some recent work on the geometric properties of the evolution of the forward rate curve in an arbitrage free bond market. The main problems to be discussed are as follows. <p> 1. When is a...</p>

We consider forward rate rate models of HJM type, as well as more general infinite dimensional SDEs, where the volatility/diffusion term is stochastic in the sense of being driven by a separate hidden Markov process. <p> Within this framework we use the previously developed Hilbert space...</p>

For finite dimensional factor models, the paper studies general quadratic term structures. These term structures include as special cases the affine term structures and the Gaussian quadratic term structures, previously studied in the literature. We show, however, that there are other,...

This paper is a selective survey of new or recent methods to extract information about market expectations from asset prices for monetary policy purposes. Traditionally, interest rates and forward exchange rates have been used to extract expected means of future interest rates, exchange rates...

The main instrument of monetary policy in industrialized countries is currently a short-term interest rate. It typically remains unchanged during long spans of time. This paper tries to answer three questions. Why do Central Banks change targeted interest rates so seldom? How should we estimate...

We summarize some methods useful in formulating and solving Hansen-Sargent robust control problems, and suggest extensions to discretion and simple rules. Matlab, Octave, and Gauss software is provided. We illustrate these extensions with applications to the term structure of interest rates, the...

In this paper we study a fairly general Wiener driven model for the term structure of forward prices. The model, under a fixed martingale measure, Q, consists of two infinite dimensional stochastic differential equations (SDEs). The first system is a standard HJM model for (forward) interest...
