This article examines non-farm employment in the context of Chinese rural institutional change, based on evidence from discrete-time logistic models for event history analysis using the Life History and Social Change survey. We find the transition to non-farm sector rose rapidly during the Great Leap Forward and market reform, while the Cultural Revolution saw it reach the lowest ebb. While male advantage prevailed exclusively during the Cultural Revolution and early marketization, education possessed a stable positive effect in all historical periods. Although the returns to different kinds of political capital vary along with institutional dynamics, intergenerational reproduction was greatly reduced after the Cultural Revolution.  相似文献

ABSTRACT

The paper presents a new combined annual cost of living and consumer price index for Norway covering 1492–2018, indicating that Norwegian price history has to be revised. The new historical price index is constructed on a significantly richer data material, which also makes it cover a longer period of price history than the existing one. This is made possible by the compilation of quantitative data from numerous sources, mostly originating from the eighteenth, nineteenth and early twentieth centuries, with grain prices stretching back to 1492. The new combined cost of living and consumer price index is constructed by a Laspeyres approach with shifting baskets for commodities and expenditure groups.

The index makes it possible to follow annual inflation and deflation in Norway for a period of 526 years. When comparing to existing indices, the new series reveals that revisions are needed in Norwegian price history. These make the historical price development more in line with those of the neighbouring countries and more in line with the pattern of wholesale prices.  相似文献

With regional science now into its seventh decade, it is timely to step back and look at what regional science is about, the past challenges it has faced, particularly its relevance, and to identify some of the challenges it has confronted in the past and at present. The paper demonstrates regional science research has had, and continues to have, policy relevance, as well as being relevant for business, and has addressed important issues. It provides an overview of recent commentaries on issues regional scientists might now be addressing.  相似文献

Following the approach of interpolation, this paper proposes the multiple exponential decay model to fit yield curves for both the U.S. TIPS market and the conventional Treasury security market. Several estimation methods, including the unconstrained/constrained nonlinear minimization, quadratic programming, and the iterative linear least squares, are applied to estimate the unknown parameters according to different curve‐fitting purposes. Comparisons between the proposed model and the alternatives show that the multiple exponential decay successfully (1) adapts to a variety of shapes associated with yield curves, (2) (partially) keeps in line with the economic interpretations of Nelson–Siegel summarized by Diebold and Li ( 2006 ), and (3) dominates the competing models in curve‐fitting performance measured by mean fitted‐price errors over the sample period. In addition, the exact specification of a nonparametric interpolation model is pinned down by applying three statistical tools, which enable us to jointly take into account validity, optimality, and parsimoniousness of the proposed model.  相似文献

This article challenges both contemporary and classic urban theory by analyzing the historical case of coastal Ecuador. Working from primary and secondary sources, I track the urbanization of coastal Ecuador during the long nineteenth century, when cacao exports determined not only the economic wellbeing of the city of Guayaquil, but of the entire tropical lowland region. I argue that this extended urban geography was both experienced and practiced as an unbounded economic and cultural region. As the value of cacao exports skyrocketed, capitalists in the city invested in infrastructural projects and financial instruments, divorcing money‐making from cacao production. After the Gran Incendio (great fire) of 1896, the city was rebuilt according to the ideals of modern liberal planning that further separated the city from the country symbolically, despite their continued material interconnection. This work suggests that long histories of capitalist urbanization provide material and theoretical support for critiquing bounded urban theory both past and present, by moving beyond the city and highlighting the processes undergirding spatial production under capitalist social relations. Likewise, this historical case study argues that city‐centrism, rather than being constituted epistemologically, was tied to liberal notions of the urban based on nineteenth‐century ideologies of modernization and progress.  相似文献

A tale of two Italies: ‘access-orders’ and the Italian regional divide   总被引:1,自引:0,他引:1  
ABSTRACT

This paper uses the ‘access orders’ paradigm developed by North, Wallis, and Weingast [(2009). Violence and social order: A conceptual framework for interpreting recorded human history. Cambridge: Cambridge University Press] to analyse the case of the Italian North–South economic divide. In line with their framework, we collect and discuss several social and political indicators over the long-run, at the regional level. Firstly we looked at data on the pre-conditions for the establishment of an open-access order, such as murders per capita (a proxy for control over violence), voting turnout and referendums participation (proxies for political legitimacy), and the impersonality of exchange. We then showed evidence of different access orders in the North and in the South, using the information on human capital formation, women participation in the labour market, and referendum results. On the basis of this evidence, we argue that, despite being part of the same State and subject to the same formal institutions, the North of the country progressively developed into an open-access order, while the South remained a form of limited access order.

Institutional differences are linked to specific aspects of the economic performance of the two areas, thus the ‘access order’ paradigm appears to be an effective conceptual scheme to explain the North–South economic divide.  相似文献

We examine investment in bank branches on the Indian subcontinent in 1939 and 1946. In 1947, the states of India and Pakistan were created from the erstwhile colony of British India. Partition was destabilizing to both economies. We use branch expansion as a proxy for entrepreneur's pre‐partition predictions of the future of these regions. Our results indicate there were no premonitions of economic dislocation. Banks tended to deepen their presence in regions which were already developed. But controlling for the level of 1931 development, branch placement was highest in exactly those regions, Bengal and the Punjab, which were to experience the greatest negative consequences from political division. After 1947, multiple banks failed; most failing banks were registered in the Punjab or Bengal region. In United India, businessmen saw as much promise in regions which were to become Pakistan as in regions which were to become India. After partition, the Pakistan regions were immediately more economically fragile. This event provides a general lesson. Economic integration had intensified over the years of British rule. The abrupt stop to integration harmed especially the smaller, less diversified region. Politicians should be wary of politically dividing regions which have evolved to function as integrated economic units.  相似文献

为了消除在构建谱聚类算法的相似矩阵时,高斯核函数中尺度参数的波动影响,构建了一种自适应相似矩阵,并应用到谱聚类算法中。自适应相似矩阵中数据点间的距离度量采用测地距离算法,相距较近的两点间的距离近似于欧氏距离,相距较远的两点则先根据欧氏距离得到每个数据点的k个近邻点,然后累加近邻点的测地距离,由此得到每对数据点间的最短距离。两点间的局部密度用共享近邻的定义来表示,更好地刻画了数据集的本征结构。在5个人工数据集和国际通用UCI数据库中的5个真实数据集上进行实验。实验结果表明,所提算法的聚类准确率高于对比算法的准确率,对复杂分布数据有很强的自适应能力。研究成果为数据挖掘及机器学习提供了思路和方法。  相似文献

This paper investigates how shared history affects customers' cultural and personal values and impacts their perception of services’ responsiveness and satisfaction in a high-contact service setting (retail banking) from two countries with a shared history (France & Lebanon). Data were collected from 171 French and 141 Lebanese bank customers. Findings reveal that both cultural and personal values moderate the relationship between responsiveness and satisfaction, and that their impact is independent of each other. Further, findings show that in countries with a shared history, existing cultural models in literature may not be detailed enough to explain cross-cultural differences and similarities.  相似文献
