Theories can be produced by individuals seeking a good reputation of knowledge. Hence, a significant question is how to test theories anticipating that they might have been produced by (potentiallyâ€¦ (More)

We propose a new econometric estimation method for analyzing the probability of leaving unemployment using uncompleted spells from repeated cross-section data, which can be especially useful whenâ€¦ (More)

In this paper, we prove that, under full rank, every perfect public equilibrium payoff (above some Nash equilibrium in the two-player case, and above the minmax payoff with more players) can beâ€¦ (More)

Wnt/Î²-catenin pathway plays an important role in initiation and progression of colorectal oncogenesis. The aim of this study was to determine expression and localization of E-cadherin, Î²-catenin andâ€¦ (More)

We introduce a class of strategies which generalizes examples constructed in two-player games under imperfect private monitoring. A sequential equilibrium is belief-free if, after every privateâ€¦ (More)

The difficulties in properly anticipating key economic variables may encourage decision makers to rely on expertsâ€™ forecasts. The expertsâ€™ forecasts, however, may not be accurate. So, their forecastsâ€¦ (More)
