We model individual careers in sports and games from initial entry to eventual exit or success as a discrete-choice, finite-horizon optimization problem. We apply this model to the international game of chess and study cross-country differences in the relative success of players. While we find...

Building on the models of sticky information, we endogenize the probability of obtaining new information by introducing a switching mechanism allowing agents to choose between costly rational expectations and costless expectations under sticky information. Thereby, the share of agents with...

In this article we derive conditions which ensure the non-negativity of the conditional variance in the Hyperbolic GARCH(p; d; q) (HYGARCH) model of Davidson (2004). The conditions are necessary and sufficient for p < 2 and sufficient for p > 2 and emerge as natural extensions of the inequality constraints derived in...</2>

This paper considers a formulation of the extended constant or time-varying conditional correlation GARCH model which allows for volatility feedback of either sign, i.e., positive or negative. In the previous literature, negative volatility spillovers were ruled out by the assumption that all...

The link between aggregate profits and investment has been widely analysed through the impact of profits on net worth and therefore the firm's ability to borrow, in the presence of credit market imperfections. How the business cycle is affected if profits also affect investment through an impact...

In a two-stage R&D game of process innovation, we investigate the effect of exogenously changing R&D spillovers and market concentration on the equilibrium level of effective cost reduction, total output, profits and social welfare. Interpreting spillover as a measure of patent protection, we...

Governments often subsidize poorer groups in society to ensure their access to new drugs. We analyze here the optimal income-based price subsidies in a strategic environment. We show that asymmetric health systems can arise even though countries are ex-ante symmetric when international price...

We present a new model analyzing the effect of uncertainty faced by bookmakers. It is shown that bettors with inside information or expert analysis decrease the odds set by profit maximizing bookmakers. Data on previously unraced two year old horses and those that have raced previously are used...

The relationship between recessions and productivity has been the focus of an important body of theoretical and empirical research in the last two decades. We contribute to this literature by presenting new evidence on the evolution of productivity in the aftermath of recessions. Our method...
