This paper extends two different metafrontier models proposed by O’Donnell et al. (2008) and Huang et al. (2014) to the input-oriented distance functional form which has been mentioned by O’Donnell et al. (2008, p250) but has not been done so far partly due to endogenous problem. As noted by Kumbhakar (2013, p465), there are a few industries such as public utilizes and banks where the hypothesis of exogenous outputs is satisfied. Thus, the metafrontier framework can be used in those industries without the problem of endogeneity. The extended model is then applied to a panel of Chinese urban water utilities. The estimated results show that the average technical efficiency for Chinese urban water utilities as a whole is below 60%, indicating the presence of much technical inefficiency. Our findings also show that the ownership reform happened in China cannot guarantee the efficiency growth in public utilities. Thus, Chinese regulatory agents should deepen the reform and change the current rate of return regulation to a more incentive-based one and require utilities to improve their efficiency before applying for raising water price.
本文将O 'Donnell et al.(2008)和Huang et al.(2014)提出的两种不同的元前沿模型扩展到O 'Donnell et al. (2008, p250)提到的输入导向的距离函数形式,但由于内生问题,迄今尚未完成。正如Kumbhakar (2013, p465)所指出的,有少数行业如公共设施和银行满足外生产出假设。因此,元前沿框架可以在这些行业中使用,而不会出现内生性问题。将扩展模型应用到中国城市自来水公司的面板上。估算结果表明,我国城市自来水企业整体平均技术效率低于60%,存在较多的技术低效。我们的研究结果也表明,中国的所有制改革并不能保证公用事业效率的提高。因此,中国的监管机构应该深化改革,将现行的回报率监管转变为更基于激励的监管,并要求公用事业公司在申请提高水价之前提高效率。

This research offers a basis for spatial data management case in point that the land governance strategy denoting as a routine of digital spatial data legacy development is a major stipulation to the “land resources” and the “community services”. Until 2015, Ontario’s municipalities cover just 17% of its landmass where the municipal affairs pace complications in land use reckoned to the seven provincial plans. The Greater Golden Horseshoe Growth Plan often cloaks the multi-jurisdictional constraints, for example, the amendment of the municipal zoning ordinance, land registry and surveys, land claims and conciliations, and housing options and taxations. The emphasis is to contour: first, identification of the key attributes and entity-sets; second, structuring of the geo-relational database connecting the local activities at the dissemination areas; and finally, the thematic features of each municipality and their contiguity. On the contrary, responsible land governance in municipal affairs is obviously substance at least to the three central obligations such as approach in integrated land management, shared periphery negotiation for economic and environmental growth moratoria, and digital data automation properties and protocols. The suggestion is that a massive development of digital spatial data is necessary to readdress the municipal affairs toward responsible land governance.
土地治理战略作为数字空间数据遗产开发的一种常规,是对“土地资源”和“社区服务”的重大规范,为空间数据管理提供了实证依据。直到2015年,安大略省的自治市只覆盖了其国土面积的17%,市政事务在土地使用方面的复杂性被认为是七个省级计划的一部分。大金马蹄铁增长计划往往掩盖了多司法管辖区的限制,例如,修订市政分区条例、土地登记和调查、土地索赔和调解、住房选择和税收。重点是轮廓:首先,关键属性和实体集的识别;第二,构建连接传播地区当地活动的地理关系数据库;最后,每个城市的主题特征及其相邻性。相反,在市政事务中负责任的土地治理显然至少是三个核心义务的实质内容,如综合土地管理方法,经济和环境增长暂停的共享外围谈判,以及数字数据自动化属性和协议。建议是大规模发展数字空间数据是必要的,以解决市政事务向负责任的土地治理。

Fee Simple Obsolete Fee Simple已废弃
Pub Date : 2016-07-17 DOI: 10.2139/ssrn.2717111
L. Fennell
Urbanization has dramatically altered the way in which land generates and forfeits value. The dominant economic significance of patterns of land use and the opportunity costs of foregone complementarities have made the capacity to reconfigure urban property essential. Yet the architecture of our workhorse tenure form — the fee simple — is ill-suited to meet these challenges. The fee simple grants a perpetual monopoly on a piece of physical space — an ideal strategy when temporal spillovers loom large, interdependence among parcels is low, most value is produced within the four corners of the property and cross-boundary externalities come in forms that governance strategies can readily reach. But times have changed. Categories of externalities that were once properly ignored by the fee simple have become too important to continue neglecting. This paper argues for alternative tenure forms that would move away from the endless duration and physical rootedness of the fee simple.
城市化极大地改变了土地产生和丧失价值的方式。土地使用模式的主要经济意义和放弃互补性的机会成本使得重新配置城市财产的能力至关重要。然而,我们的主力终身聘用制的架构——简单收费制——并不适合应对这些挑战。当时间溢出效应明显、地块之间的相互依赖性较低、大部分价值是在地块的四个角落内产生的、跨境外部性以治理策略容易达到的形式出现时,这种收费模式是一种理想的策略。但是时代变了。曾经被简单主义者适当忽视的外部性类别,已经变得太重要了,不能再继续忽视了。本文提出了另一种终身教职形式,这种形式将摆脱终身教职的无限持续时间和物理根基。

Labour Market Dynamics Following a Regional Disaster 区域性灾难后的劳动力市场动态

The 2010/2011 Canterbury earthquakes caused major upheaval to the people of the region. The second major quake killed 185 people, forced many from their homes, and closed Christchurch’s central business district. This paper examines the consequential effect on jobs and accumulated earnings for workers in Canterbury. In addition, we examine concurrent decisions about employment location, including job-to-job transitions and regional migration. While Canterbury workers’ employment outcomes were adversely affected in the short-run, those workers were more likely to have jobs three years later (relative to a matched control group), and to have higher accumulated earnings. At the same time, they were less likely to be at the same employer, and more likely to have migrated to jobs in other New Zealand regions. Impacts vary substantially by worker characteristics and by the naturally-induced geographic variation in the severity of the shock. We show that the Earthquake Support Subsidy appears to have influenced the extent of outward migration decisions, at least for most types of workers, though not the long-term retention of the pre-quake job under which the subsidy was gained. We interpret these findings as evidence that the subsidy achieved its goal of delaying involuntary job loss and, as a result, fewer workers made immediate decisions to leave the region – decisions that persisted over the long-run.
2010/2011年的坎特伯雷地震给该地区的人民带来了巨大的动荡。第二次大地震造成185人死亡,许多人被迫离开家园,并关闭了基督城的中央商务区。本文考察了对坎特伯雷工人的就业和累积收入的相应影响。此外,我们还研究了关于就业地点的并发决策,包括工作到工作的转换和区域迁移。虽然坎特伯雷工人的就业结果在短期内受到不利影响,但这些工人更有可能在三年后找到工作(相对于匹配的对照组),并且积累了更高的收入。与此同时,他们不太可能在同一个雇主工作,更有可能迁移到新西兰其他地区工作。冲击因工人的特点和自然引起的冲击严重程度的地理差异而有很大差异。我们表明,地震支持补贴似乎影响了向外迁移决策的程度,至少对大多数类型的工人来说是如此,尽管对获得补贴的地震前工作的长期保留没有影响。我们将这些发现解释为补贴实现了延迟非自愿失业的目标的证据,因此,更少的工人立即决定离开该地区——这些决定长期存在。

Private Rental-Led Gentrification in England: Displacement, Commodification and Dispossession 英国私人租赁主导的中产阶级化:流离失所、商品化和剥夺
Pub Date : 2015-12-01 DOI: 10.2139/ssrn.2717489

While central to early gentrification studies, the idea that social and tenure changes were inseparably linked to displacement has recently fallen out of research in the field. This has led to difficulties in the context of a recent shift in the tenure trajectory associated with gentrification. While the process has historically been linked to an increase in home ownership in the UK, the situation today is marked by the return of the private rental sector, a return associated with the rise of buy-to-let investors, the loss of social housing and quickly escalating rents. Gentrification operating in the UK today must thus be thought of as private rental-led gentrification ? transitions to private rental in the context of social upscaling. This is shown through a detailed comparison of small-area social and tenure data from the 2001 and 2011 UK Censuses. While this tenure shift has been documented in gentrifying areas over the years, little is known about its impacts on local neighbourhoods. This is a dangerous blind-spot as private rental-led gentrification is more pernicious than gentrification linked to ownership: it is currently more widespread and likely to displace poorer residents, creates commodified spaces and its production dispossesses low-income owners.
虽然这是早期中产阶级化研究的核心,但社会和土地使用权的变化与流离失所有着不可分割的联系,这一观点最近已经从该领域的研究中消失了。这在最近与士绅化相关的任期轨迹转变的背景下导致了困难。虽然这一过程在历史上与英国房屋所有权的增加有关,但今天的情况是以私人租赁部门的回归为标志的,这种回归与购买出租投资者的增加、社会住房的损失和租金的迅速上涨有关。因此,今天在英国进行的中产阶级化必须被认为是私人租赁主导的中产阶级化?在社会升级的背景下向私人租赁的过渡。这是通过2001年和2011年英国人口普查的小区域社会和使用权数据的详细比较显示的。虽然这种权属转换多年来一直记录在高档化地区,但人们对其对当地社区的影响知之甚少。这是一个危险的盲点,因为以私人租赁为主导的中产阶级化比与所有权相关的中产阶级化更有害:它目前更普遍,更有可能取代较贫穷的居民,创造商品化的空间,其生产剥夺了低收入业主。

Gentrification and the Rising Returns to Skill 中产阶级化和技能回报的上升
Pub Date : 2015-11-01 DOI: 10.3386/W21729
L. Edlund, Cecilia Machado, María Micaela Sviatschi
In 1980, housing prices in large US cities rose with distance from the city center. By 2010, that relationship had reversed. We propose that the inversion can be traced to more hours worked by the skilled. Scarce non-market time downgrades the importance of residential space and upgrades that of proximity to work, factors favoring the central-city location. Geo- coded census micro data covering the 27 largest US cities and the period 1980-2010 support our hypothesis: full-time skilled workers are more likely to locate in the city center and their growth can account for the observed price changes.
1980年,美国大城市的房价随着距离市中心的距离而上涨。到2010年,这种关系发生了逆转。我们认为,这种倒置可以追溯到熟练工人工作的时间更长。稀缺的非市场时间降低了居住空间的重要性,并提升了靠近工作地点的重要性,这些因素有利于市中心的位置。覆盖美国27个最大城市和1980-2010年期间的地理编码人口普查微观数据支持我们的假设:全职技术工人更有可能位于市中心,他们的增长可以解释观察到的价格变化。

The Robustness of the Effects of Public Investment in Infrastructure on Private Output: Evidence for Germany 基础设施公共投资对私人产出影响的稳健性:以德国为例

This paper investigates the effects of public investment in infrastructure on private output for Germany. Using a multivariate framework we explore the impact of a diverging selection of variables on the ensuing estimates and document confidence intervals computed following the bootstrap procedure. Our results suggest that the effect of public investment in infrastructure is positive on GDP and private investment while the labor market is negatively affected. However, the size of the estimated effects strongly depends on the choice of the variables. Furthermore, an investigation of a recursive estimation reveals that the estimated effects decrease over time.

Does Public Transit Reduce Car Travel Externalities? 公共交通能减少汽车出行的外部性吗?
Pub Date : 2015-01-20 DOI: 10.2139/ssrn.2553773
Martin W. Adler, Jos N. van Ommeren
One of the main unanswered questions in the field of urban economics is to which extent subsidies to public transit are justified. We examine one of the main benefits of public transit, a reduction in car congestion externalities, the so-called congestion relief benefit, using quasi-natural experimental data on citywide public transit strikes for Rotterdam. On weekdays, a strike induces car speed to decrease only marginally on the highway ring road (by 3 percent) but substantially on inner city roads (by 10 percent). During rush hour, the strike effect is much more pronounced. The congestion relief benefit is substantial, equivalent to about half of the public transit subsidy. We demonstrate that during weekends, car speed does not change noticeable due to strikes. Further, we show that public transit strikes induce similar increases in number of cyclists as number of car travelers suggesting that bicycling-promoting policies to reduce car congestion externalities might be attractive.
在城市经济学领域,一个悬而未决的主要问题是对公共交通的补贴在多大程度上是合理的。我们使用鹿特丹全市公共交通罢工的准自然实验数据,研究了公共交通的主要好处之一,即减少汽车拥堵的外部性,即所谓的拥堵缓解效益。在工作日,罢工导致高速公路环线上的车速只略微下降(下降3%),但内城道路上的车速却大幅下降(下降10%)。在交通高峰期,罢工的影响更为明显。缓解拥堵的好处是可观的,大约相当于公共交通补贴的一半。我们证明,在周末,由于罢工,汽车速度不会发生明显变化。此外,我们表明,公共交通罢工导致骑车者数量的增加与汽车旅行者数量的增加相似,这表明促进骑自行车的政策减少汽车拥堵的外部性可能是有吸引力的。

Can Local Housing Ordinances Prevent Neighborhood Destabilization? 地方房屋条例能防止社区不稳定吗?
Pub Date : 2014-10-28 DOI: 10.2139/ssrn.2515829
Thomas J. Fitzpatrick, Lisa Nelson, F. Richter, S. Whitaker
This paper assesses the ability of local housing ordinances to prevent neighborhood destabilization. We evaluate the degree to which vacancy registrations and point-of-sale inspection requirements influenced housing market outcomes following the housing crisis. With comprehensive real property data from Cuyahoga County, Ohio, we measure outcomes that characterize housing market distress including foreclosures, sales below the tax-assessed value, bulk sales, flipping, and property tax delinquency. We compare outcomes across properties in regulated and unregulated municipalities using matching procedures on linked data containing property, loan, and transaction characteristics. We find evidence that vacancy registrations substantially reduce foreclosures. Registrations are also negatively associated with tax delinquency and sales below a property’s tax-assessed value in some specifications. In contrast, we find little evidence that point-of-sale inspections reduce undesirable transactions. Rather, properties in cities with inspection requirements displayed higher levels of foreclosure and tax delinquency relative to the control group during the study period.
本文评估了地方住房条例防止邻里不稳定的能力。我们评估了空置登记和销售点检查要求对住房危机后住房市场结果的影响程度。根据俄亥俄州凯霍加县的综合房地产数据,我们衡量了住房市场困境的特征,包括丧失抵押品赎回权、低于税收评估价值的销售、大宗销售、倒卖和财产税拖欠。我们使用包含财产、贷款和交易特征的关联数据的匹配程序,比较了受监管和不受监管城市的财产结果。我们发现有证据表明,空置登记大大减少了丧失抵押品赎回权。在某些规范中,注册也与税收拖欠和低于房产的税收评估价值的销售负相关。相比之下,我们发现很少有证据表明销售点检查减少了不受欢迎的交易。相反,在研究期间,与对照组相比,有检查要求的城市的房产显示出更高的止赎率和税收拖欠率。

We evaluate the degree to which vacancy registrations and point-of-sale inspection requirements influenced housing market outcomes following the housing crisis.

We compare outcomes across properties in regulated and unregulated municipalities using matching procedures on linked data containing property, loan, and transaction characteristics.

Pub Date : 2014-09-15 DOI: 10.2139/ssrn.2548719

The main idea of the article is that the position and state of the municipality are directly related to the lives and prosperity of thousands and even millions of people who are carriers of culture, mentality, and employment potential of the area. Sustainability of the municipality is determined by a number of economic, social, environmental, spiritual and moral factors. The authors’ study has showed the importance of the spiritual and moral aspects of sustainable development in the modern conditions. The system stability is reduced due to dependence on external factors. It determines the need for more efficient use of factors related to the internal effects on the municipality and creates the preconditions for growth through its own potential.
这篇文章的主要思想是,市政当局的地位和状态直接关系到成千上万甚至数百万人的生活和繁荣,他们是该地区文化、心态和就业潜力的载体。城市的可持续性是由一系列经济、社会、环境、精神和道德因素决定的。作者的研究表明,在现代条件下,可持续发展的精神和道德方面的重要性。由于对外界因素的依赖,降低了系统的稳定性。它决定了需要更有效地利用与市政当局内部影响有关的因素,并通过其自身的潜力为增长创造先决条件。
