We study concurrent games with finite-memory strategies where players are given a Büchi and a mean-payoff objective, which are related by a lexicographic order: a player first prefers to satisfy its Büchi objective, and then prefers to minimise costs, which are given by a mean-payoff function. In particular, we show that deciding the existence of a strict Nash equilibrium in such games is decid...

This paper investigates how interest rates on liquid assets and excess returns on risky assets are determined when only safe assets can be used as liquid assets when waiting for an informative signal of future payoffs. In particular, we carefully differentiate between a demand for liquid assets while waiting for new information and a demand for safe assets for precautionary reasons. Employing K...

The paper presents a complete information model of bidding in second price sealed-bid and ascending-bid (English) auctions, in which potential buyers know the unit valuation of other bidders and may spitefully prefer that their rivals earn a lower surplus. Bidders with spiteful preferences should overbid in equilibrium when they know their rival has a higher value than their own, and bidders wi...

Battigalli and Siniscalchi’s [Journal of Economic Theory 106, 356-391 (2002)] notion of “strong belief”in conditional probability systems and Yang’s [Journal of Economic Theory, forthcoming] notion of “weak assumption”in lexicographic probability systems are unified by the same requirements on preferences. Our analysis, hence, reconciles the tension between Battigalli and Siniscalchi’s characte...

Ambiguity preferences are important to explain human decision-making in many areas in economics and finance. To measure individual ambiguity preferences, the experimental economics literature advocates using incentivized laboratory experiments. Yet, laboratory experiments are costly and require a lot of time and administrative effort. This study develops an ambiguity preference survey module th...

Optimal feeding is often constrained by predation avoidance, which may direct feeding to take place on more sheltered, but less profitable, parts of the habitat. Though constrained, feeding preferences and/or digestive capabilities should coevolve with the energetic and nutritional needs of the animal. These needs, as well as risk taking for these goals, may differ between the sexes. We studied...

Coastal lagoons are known to host numerous resident and migrant fish species. Spatio-temporal variation in abiotic biotic conditions these ecosystems results, however, a mosaic of microhabitats that could differently affect juvenile growth survival. To deepen our understanding habitat requirements their spatio-temporal use lagoons, microhabitat characteristics assemblages were monitored jointly...

this study investigated language learning styles of iranian efl learners and their class achievement. to this end, sixty female ad- vanced learners of instruction and different ages (15-30), studying at a language institute in shiraz were asked to take part in the study. a 30- item language learning styles questionnaire developed by reid (1987) was employed to elicit information for the study. ...

—I compared vegetation and substrate characteristics at capture locations of three syntopic species of pocket mice (Chaetodipus: Heteromyidae) to determine differences in microhabitat affinities of these ecologically similar rodents in coastal Baja California, México. Principal components analysis revealed that capture locations of C. spinatus had disproportionately higher cover of medium and l...

The need for dynamic operation in the process industry is described by Backx et al. [1]. The economics are increasingly driven by the market and this requires flexible supply chains. In such an environment it is much harder to optimize economic performance while maintaining the required product quality and honoring operational constraints. Therefore it is expected that the current industrial st...
