We consider a single-asset investment fund that in the absence of transactions costs would hold a constant amount of wealth in the risky asset. In the presence of market frictions wealth is allowed to fluctuate within a control band: Its upper (lower) boundary is chosen so that gains (losses)...

We consider a model of daily newspapers’ competition to test the validity of the so called ”theory of the circulation spiral”. According to it, the interaction between the newspapers and the advertising markets drives the newspaper with the smaller readership into a vicious circle, finally...

This paper models UK stock market returns in a smooth transition regression (STR) framework. A variety of financial and macroeconomic series are employed that are assumed to influence UK stock returns, namely GDP, interest rates, inflation, money supply and US stock prices. STR models are...

In this paper we test the effects of temporal aggregation (disaggregation) on the efficiency of portfolio construction using the mean variance optimization approach. Using Monte Carlo techniques and empirical data from the Athens Stocks Exchange we confirm that the use of temporally aggregated...

This paper studies the endogenous structure of incentive contracts that firms' owners offer to their managers, when these contracts are linear combinations either of own profits and own revenues, or of own profits and competitor's profits or, finally, of own profits and own market share. In...

This letter proposes a simple test for the linearity of a time series. We compare the small and large samples properties of the suggested test via Monte Carlo techniques with well known time domain linearity tests. Our results suggest that the suggested test over performs the power of the other...

In a differentiated Cournot duopoly, we examine the contracts that firms' owners use to compensate their managers and the resulting output levels, profits and social welfare. If products are either sufficiently differentiated or sufficiently close substitutes, owners use Relative Performance...

This paper estimates the effects on the Greek export performance that caused by the EU accession. A simultaneous equations model of export demand and export supply has been used in order to avoid the simultaneity problem. Comparative static analysis and the residuals approach have been...

In the context of a homogenous good industry with Cournot rivalry and technological asymmetries among firms, equally skilled workers can be grouped according to their different reservation wages. Under decentralized firm-union bargaining, we show that unions may offer to firms the option to...
