Prediction of future security returns is possible by decomposing a securities price into weighted superpositions of underlying basis states, given stationary distributions of the basis states. The (ensemble) Hilbert-Huang transform (HHT) is an empirical two-step online methodology which carries...

We develop a model that captures the basic characteristics of competitively authoritarian regimes. An incumbent (government) faces a challenge from a rival (opposition). There is also an agent (bureaucracy) who can shirk and can interfere in this contest. Shirking is costly to the incumbent. The...

This study examines return and risk properties arising from the construction of fund of funds (FoF) portfolios utilising actively managed Greek equity mutual funds. The evidence documents that while average return remains constant as the number of funds included in the FoF increases, risk is...

A new method is introduced for panel-data models. Asymptotic robustness is used for a multivariate model with latent variables for a family of estimators. It is shown numerically that in comparison to standard methods we obtain: 1) better predictions in out-of-sample occasions; 2) smaller...

A recent literature has analysed the Central Bank's credibility nature and determinants. In general, a Central Bank with higher credibility can implement a more efficient monetary policy, which is expressed through lower social costs in terms of volatility of relevant variables, such as output...

This paper presents the general economic equilibrium model of the Republic of Kazakhstan. The model includes eight macroagents. Four of the macroagents, Household, Producer, Bank, Owner, are described by optimisation problems. The other four macroagents follow prescribed scenarios. All agents...
