Purpose

The primary objectives of this study are to (1) highlight subsectors and industry groups of the construction sector that are most vulnerable to weather-related disasters (with highest labor cost escalation) and (2) analyze how immediate this labor wage escalation happens in different subsector of the construction sector.

Design/methodology/approach

The research methodology consists of three steps: (i) integrating various data sources to enable measurement of the county-level labor wage changes following large-scale weather-related disasters; (ii) measuring postdisaster labor wage changes at the county level; and (iii) comparing amount and timing of postdisaster labor wage changes among all sub-sectors (and industry groups) of the construction sector.

Findings

The results show that among the three construction subsectors (Heavy and Civil Engineering Construction subsector, Construction of Buildings subsector, and Specialty Trade Contractors sub-sector), Heavy and Civil Engineering Construction subsector is the most vulnerable to weather-related disasters. The industry groups under the Heavy and Civil Engineering Construction subsector showed the same vulnerability level; however, under the Construction of Buildings subsector, Industrial Building Construction industry group showed to be the most vulnerable; and under the Specialty Trade Contractors subsector, the Building Foundation and Exterior Contractors industry group is the most vulnerable. The results also showed that in approximately 75% of the damaged counties, there were increases in wages of all construction labors, over the following three quarter after the disasters. In average, labor wages in Construction of Buildings subsector and the Specialty Trade Contractors subsector decreased by 0.6% and 0.8%, respectively, in the quarter of disaster and gradually increased by 4.4% and 4.6%, respectively, in the following three quarters. On the other hand, Heavy and Civil Engineering Construction’s labor wages did not experience this decrease right after the disasters; wages increased immediately after disasters hit the counties and continually increased by 8.6% in three quarters after the disasters. It is expected that the results of this study will help policy makers, cost estimators and insurers to have a better understanding of the post-disaster construction labor wage fluctuations.

Originality/value

This study is unique in the way it used construction labor wage data. All data are location quotient, which makes the comparison among the affected counties (with different construction size) feasible.

灾后劳工工资波动:美国建筑业不同子行业之间的比较实证分析

目的

这项研究的主要目的是(1)突出显示最容易遭受与天气有关的灾害(劳动成本上升幅度最高)的建筑行业和子行业,以及(2)分析在不同领域中这种劳动工资上升是如何立即发生的。建筑部门的子部门。

设计/方法/方法

该研究方法包括三个步骤:(i)整合各种数据源,以测量与大规模天气有关的灾难后县级劳动力工资的变化;(ii)在县一级衡量灾后劳动力的工资变化;(iii)比较建筑行业所有子行业(和行业组)的灾后劳动力工资变动的金额和时间。

发现

结果表明,在三个建筑分部门(重型和土木工程建设分部门,房屋建筑分部门和专业贸易承包商分部门)中,重型和土木工程分部门最容易受到与天气有关的灾害的影响。重型和土木工程建设子行业下的行业组显示出相同的漏洞级别;但是,在“房屋建筑”子行业中,“工业建筑”行业组显示为最脆弱的群体;在专业贸易承包商分部门下,建筑基金会和外部承包商行业组是最脆弱的群体。结果还显示,在大约75%的受灾县中,所有建筑工人的工资都有所增加,在灾难发生后的接下来的四分之三。平均而言,在灾后季度,房屋建筑分部门和专业贸易承包商分部门的劳动力工资分别下降了0.6%和0.8%,在接下来的三个季度中分别分别增长了4.4%和4.6%。另一方面,在灾难发生后,重型和土木工程建设公司的工资没有出现下降。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。在灾后季度,房屋建筑分部门和专业贸易承包商分部门的劳动力工资分别下降了0.6%和0.8%,在随后的三个季度中分别分别增长了4.4%和4.6%。另一方面,在灾难发生后,重型和土木工程建设公司的工资没有出现下降。灾后县的工资立即增加,灾后四分之三持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动。在灾后季度,房屋建筑分部门和专业贸易承包商分部门的劳动力工资分别下降了0.6%和0.8%,在接下来的三个季度中分别分别增长了4.4%和4.6%。另一方面,在灾难发生后,重型和土木工程建设公司的工资没有出现下降。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。在接下来的三个季度中,灾难季度的收入分别增长了4.4%和4.6%。另一方面,在灾难发生后,重型和土木工程建设公司的工资没有出现下降。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。在接下来的三个季度中,灾难季度的收入分别增长了4.4%和4.6%。另一方面,在灾难发生后,重型和土木工程建设公司的工资没有出现下降。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。灾后县的工资立即增加,并在灾后四分之三内持续增长8.6%。预期这项研究的结果将有助于决策者,成本估算者和保险公司更好地了解灾后建筑工人的工资波动情况。

创意/价值

这项研究在使用建筑工人工资数据方面的独特之处。所有数据都是位置商,这使得在受影响县(具有不同建筑规模)之间进行比较是可行的。
