This study investigates empirically the presence of nonlinearities in the Athens Composite Share Price Index high-frequency returns. A preliminary analysis indicates that volatility exhibits a periodic intraday inverse J-shaped pattern, associated with the opening and closing of the market....

People facing choices under uncertainty, and gamblers in particular, are often subject to statistical fallacies. This paper explores the hypothesis that if lotto players were subject to the 'gambler's fallacy', predictable fluctuations in the number of jackpots would occur. Evidence, based on a...

Initial public offerings in every stock market are offered on the average at a discount. Underpricing is, however, more pronounced in emerging markets where the regulatory environment is more restrictive. In this paper we provide data on Greek IPOs and demonstrate that the extreme underpricing...

Under the assumption of random number selection, higher moments of a lotto ticket payoff seem to exhibit a peculiar behaviour; variance (and probably skewness) rises up to some number of bets before approaching its limit from above. A close inspection of the 'simplest' expression obtained by...

Falling government and donor funding, which has traditionally supported microfinance, is followed by an expansion of financially self-sustainable Microfinance Institutions (MFIs). This development has raised the concern as to whether the social goals of traditional microfinance would be equally...

This paper examines the direction of causality between Venture Capital (VC) and innovation (proxied by patents) in Europe. We test whether causality runs from patents to VC by estimating a linear dynamic panel model and causality from VC to patents by estimating a panel count model. Evidence...

Demand for lotteries has been estimated in several countries, an important issue being whether operators set lottery payouts optimally. The question is tackled by means of a traditional demand equation in effective price and recently by a demand equation variant in jackpots, both specifications...
