This paper provides just a generalization of Becker‟s theory of allocation of time, allowing joint production, throughout a 2-step optimization process, compatible and avoiding criticism in the sense of Pollak. The model yields some interesting results, analyzed for the static vision. After doing it, we just expand the vision to a dynamic context, where the stock of time and goods are introduce...

Ireland supports a high diversity and large numbers of high latitude-nesting waterfowl during the non-breeding season. Located at the southern edge of the major flyways of many species, its mild climate ensures that feeding is rarely interrupted by freezing conditions. Some species migrate here, while others use Ireland as a stopover site, while en route to more southerly wintering areas. We th...

Over the past several years, numerous essays have examined the deterrent effects of aggressive police patrol strategies like traffic law enforcement (Jacob and Rich, 1981; Sampson and Cohen, 1988; Wilson and Boland, 1978, 1981). This essay continues this line of research. It reports on the results of a field experiment in Dayton, Ohio, designed to measure the effects of traffic law enforcement ...
