Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under reasonable modifications for this field. An open subset of economies where(More)
Sniffer tools capture protocol data. Kernelprofiling tools track function calls and events occurring in the kernel. These two types of tools help us observe external and internal behaviors of networking protocols, respectively. We need both types of data for a comprehensive view of protocol behavior. However, few tools perform these two tasks in an(More)
Agglomeration can be caused by asymmetric information and a locational signaling effect: The location choice of workers signals their productivity to potential employers. The cost of a signal is the cost of housing at that location. When workers’ marginal willingness to pay for housing is negatively correlated with their productivity, only the(More)
This paper characterizes the properties of equilibrium location patterns in an Anderson-Neven-Pal model and uses these characteristics to comprehensively find the subgame perfect Nash equilibria, most of which are not yet found in the literature. Since the external competition effect may be exactly canceled out, or internal competition strictly dominates(More)
An (A) expected (strong) bubble is said to exist if it is mutual knowledge that the price of the asset is higher than the expected (possible) dividend. By requiring common knowledge instead of mutual knowledge, the new concept of common expected bubble (common strong bubble) is developed. In a simple …nite horizon model with asymmetric information and short(More)
BACKGROUND AND PURPOSE Patients with chronic obstructive pulmonary disease (COPD) are at higher risk of stroke than those without COPD. This study aims to explore the impact of inhaled pharmacotherapy on stroke risk in COPD patients during a three-year follow-up, using a nationwide, population-based study and a matched cohort design. METHODS The study(More)
