This article builds a simple theoretical model for the optimal expected length of a franchise contract. The main outcome is
that fixed specific investment positively impacts contract duration confirming previous theoretical conjectures. Additionally,
other variables such us the price–cost margin of the franchise, the brand name or the discount factor also play a relevant
role. The empirical analysis using a large sample of franchises operating in Spain confirms the main conclusions of the model.
However, the connection found between investment and duration, although statistically robust, is weak from an economic point
of view. This result suggests the possibility that, in general, most franchisees are not in equilibrium because of the high
standardization of this contract term across franchises. In these cases, the expectation of renewal is likely to be a crucial
element of adjustment. 相似文献

The purpose of this paper is to determine how NAFTA influenced the Mexican tourism sector and its effects on the environment.
The linkage between the tourism sector and NAFTA is done through the analysis of foreign direct investment and cross-border
trade in services. The quantitative section of the paper focuses on analyzing commercial presence in the form of hotels and
restaurants, as well as the use of services abroad. The paper concludes that NAFTA represented greater certainty to investors
but was not the main driver behind the investments in tourism services. The analysis of visitors from US and Canada in Mexico
recognizes that NAFTA did not have significant impact on the tourism flow. NAAEC, on the other hand, serves in this research
as a qualitative connection between tourism sector and the environment for attending to citizen submissions on failures in
environmental law enforcement in Mexico regarding tourism projects. It is included with an economic-environmental balance
in Cancun—which shows that the greatest environmental impact is of global importance: CO2 released into the air by air transportation, followed by the local impact of water consumption, waste generation, and electricity
usage, in that order. 相似文献

In view of urgent social and environmental problems, it is important to understand the political dynamics that may promote
sustainable development and to identify the agents that make changes in this direction happen. We examine the role and authority
of a new type of actor that has recently emerged on the global stage—the social entrepreneur, who tackles social and ecological
problems with entrepreneurial means. We consider them as agents that perform functions and provide services that have been
considered to be the sole authority of states. For instance, the provision of water services has long been considered an exclusive
task of the state. The water sector therefore serves as a good example to explore how these agents come up with their own
missions and political agendas. Via an illustrative sample of social entrepreneurs from around the world, we explore their
relation to water governance in general and the hydraulic mission in particular. We propose that their innovative potential
serves as their main source of authority. Their local embeddedness along with their educational efforts, participatory goals,
and accreditation as “social entrepreneur” provide additional sources of authority. 相似文献

The major issues of medico-legal relevance in fatal falls from a height are the manner of death and the reconstruction of the event. We present a peculiar case of a fatal fall from a height of about 9 m, involving a 27-year-old woman. At the death scene investigation, no suicide notes, housebreaking marks, or signs of fight were found, thus weakening both the suicide and homicide hypotheses. Combining circumstantial, autopsy and toxicology data, the kinematic analysis of the jump/fall, and the histological evidence of a myocardial sarcoidosis involving the left ventricle, we hypothesized that the young woman might have accidentally fallen from the window because of a sudden loss of consciousness related to cardiac disease undiagnosed during life. We believe that our brief report is a good example of the powerful additional information that histological investigations can offer for reconstructing the dynamics of the event in falls from a height and other traumatic fatalities. 相似文献

The "coffin fly,"Conicera tibialis Schmitz (Order: Diptera, Family: Phoridae), is well known for its frequent occurrence on buried corpses, in some cases after postmortem intervals of even 3-5 years. The present report describes the presence of a large amount of individuals of C. tibialis inside the coffin of a buried human corpse exhumed 18 years after death in central Spain. Adults, some of them newly emerged, and empty puparia were found in connection with the remains. Such postmortem interval is significantly longer than previously known for this species and raises the question on the current state of knowledge about the use of insects for estimating the postmortem interval in old, buried remains. 相似文献

Numerous empirical studies have investigated the direction of causality between democracy and economic growth (as well as the level of income per capita), but this empirical work has been paralleled by relatively few theoretical models that endogenize the institutional structure of the regime. Moreover, the different types of autocratic regimes have received relatively little attention. This paper develops a game-theoretic model of endogenous economic policy in autocratic regimes facing a revolt or an insurgency. In this model, there are three players: the regime, the rebels, and the masses. There are three stages in the game. In the first stage, the regime determines the level of infrastructure and the tax rate. In the second stage, the masses allocate their time between production and helping the rebels. In the third stage, the regime and the rebels simultaneously choose their fighting effort levels in a contest, in which the probability of survival of the regime is determined. It is found that autocratic regimes facing a revolt endogenously sort themselves into “tinpot” regimes that maximize their consumption at the cost of their survival, and (weak and strong) “totalitarian” regimes that maximize their probability of survival at the expense of their consumption. Empirical implications of the model are derived, and the relevance of the model to public policy is discussed. 相似文献

This article examines the legal responses to infectious tuberculosis in England and France. Given that tuberculosis has re-emerged as a public health threat in both countries, the differing jurisprudence and legal frameworks of disease control in the two jurisdictions warrant examination. Two questions arise in that respect: firstly, what is the role of the State in the protection of public health in the context of tuberculosis, and secondly, to what extent can the law intervene to coerce individuals to undertake health measures for the protection of society at large. These issues reveal the tensions that exist between the individual and public interest. France and England differ greatly in their responses to such tensions. Paradoxically, France, that has traditionally embraced strong State intervention, has been reluctant to curtail individual freedoms for the benefit of public health. Conversely, England, that has tended to be more closely associated with liberalism, has been ready to accept and even promote restrictions to individual freedoms in the collective interest. 相似文献
