We develop tests for seasonal unit roots for daily data by extending the methodology of Hylleberg et al. ('Seasonal Integration and Cointegration', Journal of Econometrics, Vol. 44 (1990), No. 1–2, pp. 215–238) and apply our tests to UK and US daily stock market indices. We also investigate...

Using both traditional Mean Variance Efficient Frontier (MVEF) analysis and the Johansen (1988) procedure for the analysis of cointegrated systems we assess he gains available to a sterling based investor from diversifying an equity portfolio between four southern European stock markets –...

Recent research has separately uncovered that stock ownership strongly correlates with both expectations and realizations of stock market returns, as well as with measures of financial literacy, ability or trust.

This paper considers the relationship between congruence and encompassing. Congruence is defined formally, and though it is not testable directly, it can be tested indirectly via tests of misspecification. Empirically more than one model can appear congruent, but that which encompasses its...

Does a competitive equilibrium in a matching market provide adequate incentives for investments made before the market when utility is not perfectly transferable? This paper derives a necessary and sufficient condition for equilibrium investments to maximize surplus conditional on the matching...

We report results from a sender-receiver cheap talk game, which explores whether an individual's decision to deceive is influenced by a concern for relative standing in a reference group. We show theoretically that positively biased senders, who think they are higher in the deception...

A committee is choosing from two alternatives. If required supermajority is not reached, voting is repeated indefinitely, although there is a cost of delay. Under suitable assumptions the equilibrium analysis provides a sharp prediction. The result can be interpreted as a generalization of the...
