We explore the estimation of origin-destination (OD), city-pair, air passengers, in order to explicitly take into account spatial autocorrelation. To our knowledge, we are the …rst to test the presence of spatial autocorrelation and apply spatial econometric OD ow models to air transport....

This paper analyzes how the stability of the tacit cooperation within a fringe of sev- eral identical ?rms is a¤ected by the presence of a more e¢ cient ?rm which does not take part in their cooperative agreement. The model assumes that the ?rms of the fringe adopt ?stick and carrot?strategies...

This paper presents a theoretical economic model assessing the effects of the level of mandatory genetically modified (GM) / non-GM coexistence regulations on market and welfare outcomes. We assume vertical differentiation of GM and non-GM goods on the consumer side. Producers are heterogeneous...

We provide a generalized definition of evolutionary stability of heritable types in arbitrarily large symmetric interactions under random matching that may be assortative. We establish stability results when these types are strategies in games, and when they are preferences or moral values in...

The World Wide Web was originally a totally English-based medium due to its US origin. Although the presence of other languages has steadily risen, content in English is still dominant, which raises a natural question of how bilingualism of con- sumers of a home country a¤ects production of web...

One of the pervasive problems with means-tested public long term care (LTC) programs is their inability to prevent individuals who could a¤ord private long term services from taking advantage of public care. They often manage to elude the means-test net through strategic impoverishment. We show...

This paper analyzes the impact of labor market competition and skill-biased technical change on the structure of compensation. The model combines multitasking and screening, embedded into a Hotelling-like framework. Competition for the most talented workers leads to an escalating reliance on...

We look at the consequences of allowing public health insurance (PuHI) to be voluntary when its coverage can be supplemented in the market. PuHI redistributes with respect to risk and income, and the market is affected by adverse selection. We argue that making PuHI voluntary does not lead to...
