We derive an approximation to the expectation of the likelihood tatio test for cointegration in the vector autoregressive model. The expression depends on moments of functions of random walk, which are tabulated by simulation, and functions of the parameters, which are estimated. From this...

This paper proposes an expected utility framework for the treatment of theoretical and empirical issues in technical analysis. Circumstances are found in which a technical analysts' behaviour is 'rationalisable' and schemes for learning such rational behaviour are considered. The decision...

This paper develops a framework to test alternative market microstructure models of the bid-ask spread. If, on the one hand, information-based models result in bid and ask quotes that are non-Markovian, and the other hand, the Markov property may hold in equilibrium settings where the market...

We suggest a simple non model based procedure to recover a time series from its temporally aggregated realizations. If additional assumptions on the under lying process are intorduced, it is shown that the procedure is related to many of the former proposals in the literature. It can also be...
