Much recent political economy and political science literature views democracy in terms of political rights. This view, often referred to as electoral democracy, is particularly pronounced in the empirical literature. We reincorporate the role of civil liberties, which are at the core of modern democracy, in two ways. We identify four fundamental sources of potential differences in the evolution of political rights and civil liberties. We present systematic, robust and varied empirical evidence on the direct impact of two of these potential sources of differences using cross-national panel data and accounting for the modernization hypothesis. We obtain two noteworthy empirical results: civil liberties exhibit greater persistence than political rights in affecting subsequent outcomes; and, our main result, civil liberties are complementary to political rights when affecting subsequent outcomes, while the reverse is not the case. Consequently, one must incorporate civil liberties as a determinant of electoral democracy. More generally, both dimensions must be considered to understand the setbacks recently experienced by many democracies, despite their holding of free and fair elections.  相似文献

In an earlier study of the plague in Colyton, Devon, the household distribution of deaths was studied to see whether this provided a method of identifying the causative disease. In this article, a known epidemic of plague in the Swedish parish of Bräkne‐Hoby was studied as a means of testing out the generality of the household distribution of deaths. It was discovered that, in this case, the very heavy mortality was due to two radically different means of spreading the disease, initially the classic bubonic one through the rat flea, and latterly, and somewhat surprisingly, the pneumonic one, through the infection of the inhabitants by their own friends and neighbours.  相似文献

This paper examines the comprehensive IRS data set of state-state migration flows for evidence that differences in state income tax rates are associated with migration patterns. Using annual data on moves between every pair of states, pooled time-series cross-section regressions indicate that in the 1992–2010 period states with higher top marginal income tax rates experienced relatively greater outmigration of taxpayers and gross income. To illustrate the magnitude of the tax effect, we estimate that by 2010 cumulative losses since the enactment of New Jersey’s 2004 “millionaires’ tax” were as much as 42,000 taxpayers and $6.9 billion in annual adjusted gross income. These results suggest that sustained, relatively high income tax rates could gradually erode a state’s population and revenue base.  相似文献

In this essay, we propose the notion of real existing ‘lived’ regionalism as a rejoinder to the normative and ideological debates around new regionalism. Regional forms have shown little convergence in this age of globalized regionalization. Instead of an ideational construct or set of predictable practices, we argue that regionalism is a contested product of discourses (talk), territorial relationships (territory) and technologies (material and of power). The concept of real existing regionalism confronts the tensions between the discursive constructions and normative interventions characterizing much current regionalist debate and the territorial politics and technologies reflecting, generating and directing new state spatial strategic choices. The essay demonstrates the utility of the real existing regionalism framework through an analysis of the greenbelt, transport planning and post‐ suburbanization in Southern Ontario. We argue that regulatory institutions capture the Toronto region in a mix of rhetorical and technological change that complies with neither preconceived notions of regionalization nor the pessimism of total regional dysfunctionality. Rather, the lived experience of regionalization illuminates the emergent assemblages, multiplicity of everyday flows and ongoing multiscalar negotiations of diverse communities that produce the real existing region.  相似文献

We investigate transitions between unemployment, low‐paid employment and higher‐paid employment using dynamic panel data methods applied to household panel data. We find state dependence in both unemployment and low‐paid employment and evidence of a low‐pay no‐pay cycle. However, we also find significant differences in effects across population subgroups. Typically, the young and better‐educated face lower penalties from unemployment and low‐paid employment. Further, low‐paid employment is preferable to unemployment for women regardless of their demographic characteristics, but for men who have only completed secondary schooling, low‐paid employment actually decreases the chances of entering higher‐paid employment by more than does unemployment.  相似文献

Our aim in this paper is to evaluate the causal effect of foreign acquisition on research and development (R&D) intensity in targeted domestic firms. We are able to distinguish domestic multinational enterprises (MNEs) and non‐MNEs, which allows us to investigate the fear that the change in ownership of domestic MNEs to foreign MNEs leads to a reduction in R&D activity in the country. Overall, our results give no support to the fears that foreign acquisition of domestic firms leads to a relocation of R&D activity in Swedish MNEs. Rather, in this paper, we find robust evidence that foreign acquisitions lead to increasing R&D intensity in acquired domestic MNEs and non‐MNEs.  相似文献
