Representatives have more effective incentives to cater to the preferences of the majority of citizens when they are elected in districts with few rather than many seats. We investigate this hypothesis empirically by matching Swiss members of parliament’s voting behavior on legislative proposals with real referendum outcomes on the same issues for the years 1996 to 2008. We thus identify the impact of district magnitude on representatives’ incentives to adhere to citizens’ revealed preferences. We find systematic, statistically significant and economically relevant evidence that individual representatives from districts with few seats vote more often in line with majority preferences. 相似文献

The burial of a body can affect plant communities through mechanical disturbance and nutrient balance alteration. We performed an experimental trial using five swine carcasses buried in an open site in Italy. Vegetation dynamics was monitored recording monthly every plant individual on a regular sampling grid during 1 year on the graves, on an empty control grave, and on an undisturbed plot. Plant species composition and cover were significantly different between the disturbed and the undisturbed plots. Disturbed plots showed the increase in ruderal species and the reduction in stress-tolerant ones. Graves and the control grave could not be distinguished from each other. Disturbance was the main factor affecting plant cover, while the presence of a buried body did not affect vegetation dynamics. However, disturbance could be easily detected; the functional approach seems promising for the identification of dynamic patterns to be used in different biogeographic and ecological contexts. 相似文献

Different policies aimed at protecting intellectual property are not equally efficient. This paper provides support in favour
of those policies affecting the unit value of damage produced by infringers, contrarily to those policies aimed at reducing
the frequency of infringements. The finding has practical spillovers both in terms of policy and in terms of further research. 相似文献

We performed an experimental investigation to assess whether the “restricted auction” mechanism proposed by Berkovitch, Israel
and Zender in 1997 works effectively as an optimal bankruptcy law or not. An optimal bankruptcy law is a commitment device
that implements efficient choices both before (ex ante) and after (ex post) financial distress, even if moral hazard is binding.
We designed an experiment focused on ex ante efficiency and we found that the restricted auction mechanism was able to direct
an optimal amount of effort toward entrepreneurial activities. This result confirms the theoretical predictions. Nonetheless,
we found that under a plain unrestricted auction mechanism our experimental subjects chose to allocate into their firms a
larger amount of effort than that predicted by theory. Although difficult to justify on theoretical grounds, this experimental
evidence is robust. Our behavioral interpretation is that this result is due to “moral sentiments”, such as the natural propensity
of subjects toward socially desirable behaviors. In fact, we show that it vanishes once these motives are removed. 相似文献

In this introduction to the special issue on ‘Women's work in changing labour markets’, we argue that a combination of digital advances, notably the digitization of individual- and contextual-level data, the creation of internationally comparable occupation-based classifications, and the development of statistical models allowing for contextually informed analysis, has brought us to the brink of new developments in the field of women's work. Census and vital registration data contain more information on occupations of women than previously thought, and when used in combination with other digitized sources they allow one to assess the possible under-registration of women's work, as illustrated by some of the contributions to this special issue. Other contributions show how standardizing occupation-based classifications allows for temporal and regional comparisons of women's work and makes it feasible to study how community or regional characteristics influence that work. None of these developments – large-scale digitization of individual-level data, standardization of occupational titles and measures of stratification, and contextually informed analyses – is completely new; in some cases they are actually rooted in a venerable research tradition. However, in combination they might well constitute a cascade in the history of working women. 相似文献

Important work has been done to measure legislative effectiveness in the U.S. Congress and to explain the individual characteristics that drive it. Much less attention, however, has been devoted to study the extent to which legislative effectiveness depends on the legislators' social connections. We address this issue with a new model of legislative effectiveness that formalizes the role of social connections, and we test its predictions using the network of cosponsorship links in the 109th–113th Congresses. We propose a new empirical strategy that addresses network endogeneity by implementing a two-step Heckman correction based on an original instrument: the legislators' alumni connections. We find that social connections are a significant determinant of legislative effectiveness. We also study the influence of legislators' characteristics in shaping the network effects. In doing so, we provide new insights into how social connectedness interacts with factors such as seniority, partisanship, and legislative leadership in determining legislators' effectiveness. 相似文献

The discovery of mummified bodies in domestic settings is not unusual in the medico‐legal context. It is often a marker of social isolation, even in our urban modern society, and usually occurs among elderly people living alone or in precarious conditions. However, bereaved subjects can sometimes be found managing their grief by deliberately keeping the corpses of their loved ones at home. Investigation of these atypical cases can be challenging and often requires a multidisciplinary effort by different forensic specialists. We report two cases of people who lived for several months with the mummified remains of a relative. In both cases, the judge ordered a forensic psychiatry assessment of the survivors’ competency and the reasons for this peculiar behavior, which is regarded as abnormal in our society. Case 1 describes a shared psychosis, which developed out of a condition of extreme seclusion of the entire family. Case 2 shows that even a mild personality disorder on which a series of traumatic events operates can trigger psychotic decompensation, causing extreme denial of the reality of death. The analysis of these cases contributes to our knowledge of the scantly studied phenomenon of “Living with the Dead” and raises questions about the psychopathology behind it. It is useful to identify subjects who are more prone to developing this “deviant” behavior, in order to distinguish people with mental illness from those who merely want to profit from the death of a loved one. 相似文献

Ausgehend von den Reaktionen auf zwei ähnliche Ereignisse – die "Massaker" in Genf und Zürich im Jahre 1932 – formuliert der Artikel Hypothesen über die Erfolgsbedingungen eines bürgerrechtsorientierten Diskurses in der Öffentlichkeit. In Genf konnte sich dieser Diskurs hegemonial ausbreiten, während sich in Zürich ein Law-and-Order Diskurs durchgesetzt hat. Die Ausrichtung der Diskurse wird anhand eines politischen Modells erklärt. Die diskursiven Strategien der politischen Parteien richten sich nach a) den Allianzen mit sozialen Bewegungen, b) ihrer Position im politischen System (Regierung oder Opposition) und c) dem Wahlprozess, welchem eine Validierungsfunktion der diskursiven Optionen zukommt. Die Autoren argumentieren, dass die diskursiven Strategien der 1930er Jahre zu wichtigen und bindenden symbolischen Ressourcen für die politischen Akteure in den 70er Jahren wurden, als die Auseinandersetzung um die öffentliche Ordnung mit dem Aufkommen der neuen sozialen Bewegungen wieder auf der politischen Agenda erschien. 相似文献
