I empirically study price jumps using high frequency data comprising 5-, 10-, 15- and 30-minute market data on the main indices from the Prague, Warsaw, Budapest and Frankfurt Stock Exchanges for June 2003 to the end of 2008. I use two definitions of price jumps: the price jump index and...

The standard price competition of two or more players leads to Bertrand equilibrium in basic economic theory (if complete information is assumed, there are no capacity constraints, etc.). In reality, even on highly competitive Internet-based markets, the prices of seemingly undifferentiated...

I study the choice of technology adoption in an environment where human capital is transmitted from the old to the young generation, but the young generation can opt out for a new technology. The adoption and matching decisions are made in a sequential intergenerational bargaining. Since...

Electoral fraud has become an integral part of electoral competition both in established democracies and less-than-democratic regimes. In this paper I study electoral fraud in the non-democratic setting. First, I present evidence of fraud sustainability and growth over the lifetime of...

In the paper, I develop a theoretical model of a marriage market that accounts for the effect of aging on agents’ wealth and physical attractiveness. Furthermore, I use the model to analyze how the structure and more importantly the stability of the marriage market is affected by the increased...

Theories of fairness have typically used the assumption of ex-ante known pie size. Pie size, however, is rarely known ex ante. Using three simple allocation problems generally known as dictator, ultimatum and trust games, we explore the influence of ex-ante unknown pie size of varying degrees of...

This paper empirically analysis the price jump behavior of heavily traded US stocks during the recent financial crisis. Namely, I test the hypothesis that the recent financial turmoil caused no change in the price jump behavior. To accomplish this, I employ data on realized trades for 16 stocks...

I estimate the effect of opposite-gender peer drinking on individual risky sexual behavior among Czech youth. The identification strategy relies on two main controls for individual and group-specific unobservables. First, younger schoolmates’ sexual behavior is a control for school-specific...

In absence of a model-based measure of occupational skill-intensity, the litera- ture on wage inequality cannot consistently track technological progress on occu- pational level - a key ingredient of recent theories of labor market polarization. In this paper, I use the March CPS data from 1983...

This paper uses experimental data to investigate possible biases in consumers' choice of pricing schemes when their demand is perfectly inelastic but uncertain. I consider threepart pricing schemes (i.e. fixed fee, included units, extra-unit price). The analysis suggests a strong bias towards...
