This paper discusses the role of the credit rating agencies during the recent financial crises. In particular, it examines whether the agencies can add to the dynamics of emerging market crises. Academics and investors often argue that sovereign credit ratings are responsible for pronounced...

In this paper, we examine how the structure of an imperfectly competitive input market affects final-good producers’ incentives to form a Research Joint Venture (RJV), in a differentiated duopoly where R&D investments exhibit spillovers. Although a RJV is always profitable, downstream firms’...

This paper uses cointegration and common trends techniques to investigate empirically the expectations hypothesis of the term structure of interest rates for the 10 new EU countries, along with Bulgaria and Romania. The empirical results support the expectations theory of the term structure for...

This paper considers a panel data model with time-varying individual effects. The data are assumed to contain a large number of cross-sectional units repeatedly observed over a fixed number of time periods. The model has a feature of the fixed-effects model in that the effects are assumed to be...

This article examines a tracking problem, similar to the one presented in Pliska and Suzuki (Quantitative Finance, 2004): an investor would keep constant proportions of her wealth in different assets if markets were frictionless; however, in the presence of fixed and proportional transaction...

The present paper develops an econometric model for measuring input-oriented technical efficiency when the underlying technology is characterized by the lack of substitution between inputs. In this instances, Farrell’s radial measure of technical inefficiency is inappropriate as it may be...

Contingent Valuation studies are often characterized by a considerable amount of protest responses, which may have an important effect on the final estimates if the protest responses are not randomly distributed across the sample. If the standard procedure of censoring protest responses is...

This paper investigates whether the nominal euro exchange rate against the currencies of China, Japan, the UK and the USA converges or not to its equilibrium level. Applying cointegration and common trend techniques in the presence of structural breaks in the data, we found a valid long-run...

In this paper we provide an investigation on the potential benefits that may exist for portfolio managers, private and institutional investors from domestic portfolio diversification. We employ daily data for the period 1996-2002 from the Cyprus Stock Exchange, recently established emerging...

This paper discusses three modelling techniques, which apply to multiple time series data that correspond to different spatial locations (spatial time series). The first two methods, namely the Space-Time ARIMA (STARIMA) and the Bayesian Vector Autoregressive (BVAR) model with spatial priors...
