We use newly assembled data on regulation in several sectors of many OECD countries to provide evidence that regulatory reform of product markets is associated with an increase in investment. A component of reform that plays a very important role is entry liberalization, but privatization also has a substantial effect on investment. Sensitivity analysis suggests that our results are robust. (JEL: E22, L5) 相似文献
This study analyzed a post office clerk's tasks, comparing two workstation models. The clerk was facing the client in one, and seated at 45 degrees to the counter in the other. We analyzed the most frequent tasks and those presenting the most critical points: 1) payment of a postal order; 2) accepting a registered letter, breaking them down into subtasks. We used an optoelectronic system for kinematic analysis, and calculated the range of motion of the trunk and arms in the three spatial planes. The 45( position required less torsion of the trunk and head when using the printer, placed to the left of the employee. A larger worktop improved the workstation, leaving more room for equipment and allowing the worker to sit frontally to the monitor. However, this solution involved a shorter distance between the worker and the client with longer extension of the shoulder and elbow and less trunk flexion. These findings suggested a modification in the layout that shortens the distance between the worker and client. 相似文献
This paper presents a social norms interpretation to explain cross-country differences in partnership formation rates. Social norms are modeled as a constraint on the allocation of household labor that diminishes the gains of entering a partnership, especially for highly educated women with a higher opportunity cost of time. Results using individual level data from 7 waves of the European Community Household Panel (1995?C2001) confirm the predictions from the theory. These results are robust to controlling for country varying factors such as childcare policies and divorce rates, and are mostly driven by marriage (as opposed to cohabitation) decisions. Given that household formation is a necessary prerequisite to having children, our results potentially shed light onto the process of below replacement fertility and the economic challenges associated with it. 相似文献
This article analyzes the links between migratory processes and the evolution of nationality legislation in Spain. We argue that this case challenges the theoretical models that link immigration to liberalizing reforms in citizenship law. Despite large‐scale immigration experienced over the last two decades, Spanish nationality law has remained strongly focused on keeping ties with Spanish communities abroad. To account for the high degree of stability of Spanish citizenship law we structure our analysis along three basic lines: the historical conceptions derived from Spain's past as a colonial power, as well as its tradition as a country of emigration; the lack of incentives for political actors to introduce the reform of citizenship law in the political agenda; and the strategies adopted by those political actors in relation to the politicization of immigration. 相似文献
The estimation of the effect of local human capital on wages only might not identify properly human capital spillovers. Appropriate
identification requires considering the joint effect of local human capital on both wages and rents. Empirically, we study
the effects of local human capital on household-level rents and individual-level wages for a sample of Italian local labour
markets. Our results show a positive and robust effect of local human capital on rents, supporting the idea that human capital
generates positive externalities at the local level. Our results also suggest that consumption and production externalities
have a similar impact on wages.
A group of elderly women set up prayer camps in public roundabouts throughout Nicaragua’s capital, Managua, to pray for ‘peace and reconciliation.’ A few miles away, in a humble barrio, escaping sexual discrimination and violence, a 24-year-old transvestite performs a sexually charged act in a circus. Meanwhile, across from the national parliament, hundreds of ex-agricultural workers exposed to the pesticide nemagon exhibit their dying flesh to the nation and the world in order to expose corporate greed and government inaction. These cases, happening under the new Sandinista regime, reflect a plurality of social spaces where theatricality, as the rhetorical manipulation of spaces and bodies aiming to affect publics, has become a mechanism for revealing the interstices of power relations in present day Nicaragua. This work explores various instances of linked and entwined government-sponsored and -sanctioned social performances of power and visibility, as well as other social performances that draw attention to the gap between the rhetoric of the government and social reality. 相似文献
In this paper we propose a methodology to obtain social indicators at a detailed spatial scale by combining the information contained in census and sample surveys. Similarly to previous proposals, the method proposed here estimates a model at the sample level to later project it to the census scale. The main novelties of the technique presented are that (i) the small-scale mapping produced is perfectly consistent with the aggregates -regional or national- observed in the sample, and (ii) it does not require imposing strong distributional assumptions. The methodology suggested here follows the basics presented on Golan (2018) by adapting a cross-moment constrained Generalized Maximum Entropy (GME) estimator to the spatial disaggregation problem. This procedure is compared with the equivalent methodology of Tarozzi and Deaton (2009) by means of numerical experiments, providing a comparatively better performance. Additionally, the practical implementation of the methodology proposed is illustrated by estimating poverty rates for small areas for the region of Andalusia (Spain).
This study aimed to quantify training parameters and analyze the morphological response of aged muscles submitted to resistance training and anabolic steroids. Aged Wistar rats were divided into groups: C – initial control; CF – final control; CAS – control with anabolic steroid, RT – resistance training, and RTA – resistance training with anabolic steroid. Maximum carried load, absolute and relative loads increased significantly in RT and RTA. RTA demonstrated greater relative load than RT. Average total volume, total climbing volume, relative total volume, relative total climbing volume, and mean climbing volume were similar between groups RT and RTA. For soleus, CAS, RT, and RTA enlarged cross-sectional area of type I fibers and nuclear ratio. As for type II fibers, RTA was higher than C and CF. For plantaris, RT and RTA showed significant increases in myofibers type I compared to C and CF. For type II fibers, RTA showed a significant increase compared to C and CF. Regarding the nuclear ratio, RT and RTA showed a higher ratio than C, CF, and CAS. Our results demonstrated that both RT and RTA were not different among the analyzed morphological parameters. This fact can be explained by the absence of differences found in the training variables analyzed. 相似文献
