Human-induced earthquakes,risk salience,and housing values

Oklahoma’s households have recently faced several thousand higher-probability but low-impact earthquakes induced by nearby shale gas development. This type of seismic activity is different from natural-occurring earthquakes, which are generally constituted by one, high-loss event. We investigate the mechanisms through which earthquakes may influence household perceptions of risk by modeling changes to property values in and out of seismically-active zones. We estimate that the induced earthquakes are spatially concentrated, which is partially influenced by governmental limits placed on natural gas production and wastewater injections. Additionally, we explore the underlying measure of earthquake intensity and identify its importance in modeling seismic impacts. Controlling for the stock-flow dynamics of seismicity through time, we estimate that Oklahoma County’s cumulative experience of earthquakes led to a diminution of property values. The impacts are further exacerbated by risk-saliency effects, as reflected in declining values associated with nearby wastewater injections and natural gas production.     

独立董事能否抑制大股东的“掏空”?

本文以大股东占用上市公司资金作为研究对象,考察了在中国证券市场上,独立董事的引入能否有效抑制大股东的掏空行为。与以往研究类似,在OLS回归中,我们未能发现独立董事比例与大股东资金占用之间存在显著相关关系。进一步分析表明,中国上市公司的独立董事变量具有内生性,在控制独立董事内生性情况下,我们发现独立董事变量与大股东资金占用显著负相关。这表明以往研究未能发现独立董事能够抑制大股东掏空,很可能源于模型设定偏误。在稳健性分析部分,我们采用了多种指标来反映大股东的资金占用行为,本文结论仍然成立。     

Information regulation: Do the victims of externalities pay attention?

Individuals living in metropolitan areas are exposed to a large number of industrial risks. Information regulation is a new tool to manage such risks. We ask if large-scale information initiatives directed at the general public can affect individual risk perceptions. The answer is affirmative. Using the publication of the Toxics Release Inventory as a case study, we find a decline in predicted property values when new information on pollution became available, indicating that homebuyers adjusted their risk perceptions upward. The response, however, is limited to sources of toxic emissions that are located at a moderate distance from the properties in our sample.      

Rural light pollution from shale gas development and associated sleep and subjective well-being

The shale oil and gas boom has had large economic, environmental, and social impacts on rural communities in the United States. This study provides novel estimates of the impacts of shale oil and gas development on light pollution in rural areas of the United States. Using nationwide, time-calibrated DMSP-OLS database from 2000 to 2012, we find robust evidence that the shale oil and gas boom significantly increased light pollution in rural areas. We then assess associations between horizontal drilling and subjective self-rated health using nationwide data from the Behavioral Risk Factor Surveillance System (BRFSS) from 2000 to 2012. Our findings suggest that insufficient sleep and poor health (physical or mental) are associated with increased drilling in rural areas. These results provide support for drilling-related light pollution as an additional environmental pathway of concern for public health beyond the mechanisms of air or water pollution.     

THE IMPACT OF STADIUM ANNOUNCEMENTS ON RESIDENTIAL PROPERTY VALUES: EVIDENCE FROM A NATURAL EXPERIMENT IN DALLAS-FORT WORTH

We investigate the impact of a potential new sports venue on residential property values, focusing on the National Football League's Dallas Cowboys' search for a new host city in the Dallas-Fort Worth area. We find that residential property values in the city of Dallas increased following the announcement of a possible new stadium in the city. At the same time, property values fell throughout the rest of Dallas County, which would have paid for the proposed stadium. These patterns reversed when the Dallas stadium proposal was abandoned. Subsequently, a series of announcements regarding a new publicly subsidized stadium in nearby Arlington, Texas, reduced residential property values in Arlington. In aggregate, average property values declined approximately 1.5% relative to the surrounding area before stadium construction commenced. This decline was almost equal to the anticipated household sales tax burden, suggesting that the average expected amenity effect of hosting the Cowboys in Arlington was not significantly different from zero.

THE PROPERTY VALUE PREMIUM OF A PLACE OF WORSHIP

Using a unique data set of residential housing values, we improve on previous hedonic pricing and event studies literature to estimate the amenity effects of a new religious structure on local property values. We improve on previous research by extending our analysis with a pre‐ and post‐treatment model. Using a pre‐ and post‐treatment model, we do not find that the religious structure that we examined influenced the value of surrounding properties in the period after its completion. The results suggest that previous research using only post‐completion data may mischaracterize the amenity effects of religious structures. (JEL R3)     

Evaluating the risk premium in the U.S.A. natural gas market: evidence from low-price regime

In recent years, the U.S.A. natural gas market has seen enormous changes. The expectations of abundant supply of shale gas and the slow U.S.A. economic recovery have pushed gas prices below US$ 4 MMBtu. Although shale gas is a new promising source of unconventional energy, investors face uncertain investment plans. In this study, we investigate the risk premium by comparing behaviour before and after the change point in agents risk perception. Unlike traditional empirical research on risk premium, we use the parametric, two-factor model of Schwartz and Smith (2000) to evaluate the implied risk premium term structure from futures prices traded on the New York Mercantile Exchange (NYMEX). We compare our findings with other empirical results and find that the change point lies at the beginning of the low-price regime. When we compare periods before and after the change point, we observe that the risk premium changed, not only in sign, but also in magnitude.     

Do shale gas and oil productions move in convergence? An investigation using unit root tests with structural breaks

This paper investigates the long-run trends of shale gas and shale oil productions by applying univariate and panel Lagrange Multiplier (LM), GARCH-based, and PANICCA unit root tests to discover the mean-reverting behaviors. We employ monthly data from January 2007 to December 2016 of shale gas withdrawals and shale oil productions in the U.S. The empirical results both on specific state/oil well and panel data show that most structural breaks emerge around 2007–2011, during which shale energy was massively produced in the U.S. and the global financial crisis and energy shock occurred. Our results also indicate that most external shocks are transitory and the trends soon converge, and that cross-state/well factors have greater potential as temporary shocks than the state-specific/well-particular components. For robust analysis, we conduct additional LM tests of natural gas and crude oil productions for a comparison with the unconventional shale energy. The unit root test of Narayan and Popp (2010) on shale gas and shale oil productions help us to find more stationary evidence. Overall, we present powerful findings of the mean-reversion property and propose critical implications for authorities and market participants.     

Impacts of natural resource management technologies on agricultural yield and household income: The system of rice intensification in Timor Leste

Natural resource management (NRM) technologies, such as the system of rice intensification (SRI), have been proposed to tackle agricultural challenges such as decreasing productivity growth and environmental degradation. Yet, the benefits of NRM technologies for farmers are often debated. Impacts seem to be context-specific, which are especially relevant in the small farm sector with its large degree of agroecological and socioeconomic heterogeneity. This was not always considered in previous research. We analyze the impacts of SRI adoption on rice yield and household income among smallholder farmers in Timor Leste. Heterogeneity is accounted for in an endogenous switching regression framework. Comparing mean yield and income levels, we find no significant differences between SRI adopters and non-adopters. This is due to negative selection bias; SRI seems to be adopted more on plots and by farmers with less than average yields. Controlling for this bias reveals significant yield and income gains. Poor and non-poor households benefit from SRI adoption; small farms benefit more than larger farms. The results also suggest that in the context of Timor Leste SRI may not be beneficial when compared to conventional rice grown under favorable conditions. Some implications for future research are discussed.     

Time consuming resource extraction in an overlapping generations economy with capital

For worldwide fisheries production, two major trends emerge for the next decades: a significantly larger role for aquaculture and reduced output due to climate change impacts. While the former leads to an increase in cost, the latter affects natural regeneration. To address both impacts, we investigate the relevance of resource extraction costs for a private property fishery in an intertemporal general equilibrium model with capital accumulation, commodity production and a labor market. We show how the extraction cost parameter—in addition to time preference, technology and natural regeneration—matters for the existence (and stability) of an economically feasible, nontrivial stationary state. Higher extraction costs increase the equilibrium resource stock, while a reduced regeneration rate (e.g. due to climate change) decreases the stock. Moreover, resource extraction overshoots its new equilibrium value after the cost shock while after a regeneration shock extraction levels adjust monotonically towards the new equilibrium.     

环境规制工具与环境友好型技术创新：知识产权保护的双门槛效应

环境规制对技术创新的影响是当前学术界研究热点,已有大量基于“波特假说”的实证研究。然而，对于环境规制工具是否以及如何影响环境友好型技术创新，学术界尚未达成共识。而且，从理论上讲，“波特弱假说”涉及双重外部性问题，即技术创新的正外部性和环境污染的负外部性，需要环境规制和知识产权保护合力解决，而知识产权保护未引起普遍重视。采用中国内地30个省、市（区）2004－2019年面板数据，构建基于知识产权保护强度的动态门槛模型，实证检验知识产权保护在环境规制工具影响环境友好型技术创新中的作用机理。研究发现：3类环境规制工具对环境友好型技术创新的影响存在以知识产权保护强度为门槛的双重门槛效应。具体而言，市场激励型环境规制工具随着知识产权保护强度跨过第一门槛值呈现由负向抑制到正向促进的阶段性突变趋势；命令控制型环境规制工具随着知识产权保护强度跨过第二门槛值呈现由正向促进到负向抑制的阶段性突变趋势；公众参与型环境规制工具在知识产权保护强度介于两个门槛值之间时，对环境友好型技术创新的促进效应显著。     

A shaky business: Natural gas extraction,earthquakes and house prices

The production of natural gas is strongly increasing around the world. Long-run negative external effects of extraction are understudied and often ignored in (social) cost-benefit analyses. One important example is that natural gas extraction leads to soil subsidence and subsequent induced earthquakes that may occur only after a couple of decades. We show that induced earthquakes that are noticeable to residents generate substantial non-monetary economic effects, as measured by their effects on house prices, also when house owners are fully compensated for damage to their houses. To address the issue that earthquakes do not occur randomly over space, we use temporal variation in the occurrence of noticeable earthquakes while controlling for the occurrence of earthquakes that cannot be felt by house owners. We find that earthquakes that are noticeable with peak ground velocities of above half a cm/s lead to price decreases of 1.9 percent. The total non-monetary costs of induced earthquakes for Groningen are about €170 million (about €600 per household). These results indicate that the non-monetary costs are in the same order of magnitude as the monetary damage costs.     

Who Wins from Emissions Trading? Evidence from California

Researchers and environmental policy advocates have raised questions regarding the distributional impacts of emissions trading programs, a.k.a. “cap-and-trade”. While previous research has been careful to identify the causal effect of emissions trading on emissions reductions (Fowlie et al. in Am Econ Rev 102(2):965–993, 2012, hereafter FHM), we argue that existing estimates of differential impacts on demographic groups have relied on unrealistic assumptions regarding pollution dispersion. In this paper, we estimate the emissions reduction due to the RECLAIM cap-and-trade program in Southern California following the identification strategy of FHM, but we relax the assumption of uniform dispersion surrounding point sources. We model the transport of effluents using a state-of-the-science dispersion model to determine the areas impacted by emissions from each source. Importantly, conditional on race and ethnicity, we find that higher income areas receive larger reductions in pollution under cap-and-trade. Furthermore, conditional on income (or poverty rates), we find that Blacks benefit while Hispanics lose relative to whites under RECLAIM.     

过程、结果维度的环境治理与企业财务绩效

目前国内外对于环境治理与企业财务绩效之间关系的研究,结论不一致且不能有效比较,可能是由于没有区分环境治理的不同维度,而高成本的环境治理过程与环境治理结果之间的关系尚不明确。本文基于2009—2017年A股公司年报手工搜集企业环境治理数据,基于权衡理论、自然资源理论和TLGT效应等,检验了环境治理过程和结果与企业财务绩效之间的非线性关系。结果发现:环境治理过程正向影响环境治理结果,而环境治理过程和结果两个维度都与企业财务绩效呈U型关系,较差的环境治理过程和结果均负向影响财务绩效,而较好的环境治理过程和结果均正向影响财务绩效,并且环境治理结果在环境治理过程和企业财务绩效之间发挥非线性中介作用。进一步检验发现,过程维度的环境治理仅通过成本效应路径影响财务绩效,而结果维度的环境治理同时通过成本效应路径和差异化效应路径影响财务绩效。本文基于中国的制度背景将环境治理划分为治理过程和治理结果两个维度,为企业环境治理与财务绩效之间的关系提供了经验证据,并对促进中国企业环境治理提供了一定启示。     

Precautionary saving under many risks

This paper studies precautionary saving when many small risks are considered. We first introduce two simultaneous risks: labor income and interest rate risks. We show that, in this context, sufficient conditions for precautionary saving are weaker than in similar models. Moreover, we find that, unlike previous literature, precautionary saving can occur in the case of negative covariance between the two risks and in the case of imprudence. We then extend our analysis to a three-risk framework, where a background risk is included. We derive sufficient conditions for precautionary saving which are interpreted in the light of the previous literature.     

The effects of low income housing tax credit developments on neighborhoods

This paper evaluates the impacts of new housing developments funded with the Low Income Housing Tax Credit (LIHTC), the largest federal project based housing program in the U.S., on the neighborhoods in which they are built. A discontinuity in the formula determining the magnitude of tax credits as a function of neighborhood characteristics generates pseudo-random assignment in the number of low income housing units built in similar sets of census tracts. Tracts where projects are awarded 30% higher tax credits receive approximately six more low income housing units on a base of seven units per tract. These additional new low income developments cause homeowner turnover to rise, raise property values in declining areas and reduce incomes in gentrifying areas in neighborhoods near the 30th percentile of the income distribution. LIHTC units significantly crowd out nearby new rental construction in gentrifying areas but do not displace new construction in stable or declining areas.     

The Amenity Value of English Nature: A Hedonic Price Approach

Using a hedonic property price approach, we estimate the amenity value associated with proximity to habitats, designated areas, domestic gardens and other natural amenities in England. There is a long tradition of studies looking at the effect of environmental amenities and disamenities on property prices. But, to our knowledge, this is the first nationwide study of the value of proximity to a large number of natural amenities in England. We analysed 1 million housing transactions over 1996–2008 and considered a large number of environmental characteristics. Results reveal that the effects of many of these environmental variables are highly statistically significant, and are quite large in economic magnitude. Gardens, green space and areas of water within the census ward all attract a considerable positive price premium. There is also a strong positive effect from freshwater and flood plain locations, broadleaved woodland, coniferous woodland and enclosed farmland. Increasing distance to natural amenities such as rivers, National Parks and National Trust sites is unambiguously associated with a fall in house prices. Our preferred regression specifications control for unobserved labour market and other geographical factors using Travel to Work Area fixed effects, and the estimates are fairly insensitive to changes in specification and sample. This provides some reassurance that the hedonic price results provide a useful representation of the values attached to proximity to environmental amenities in England. Overall, we conclude that the housing market in England reveals substantial amenity value attached to a number of habitats, designations, private gardens and local environmental amenities.     

The economic impact of shale gas extraction: A review of existing studies

Recent advances in drilling technology have allowed for the profitable extraction of natural gas from deep underground shale rock formations. Several reports sponsored by the gas industry have estimated the economic effects of the shale gas extraction on incomes, employment, and tax revenues. None of these reports has been published in an economics journal and therefore have not been subjected to the peer review process. Yet these reports may be influential to the formation of public policy. This commentary provides written reviews of several studies purporting to estimate the economic impact of gas extraction from shale beds. Due to questionable assumptions, the economic impacts estimated in these reports are very likely overstated.     

Economic Analysis for the UK National Ecosystem Assessment: Synthesis and Scenario Valuation of Changes in Ecosystem Services

We combine natural science modelling and valuation techniques to present economic analyses of a variety of land use change scenarios generated for the UK National Ecosystem Assessment. Specifically, the agricultural, greenhouse gas, recreational and urban greenspace impacts of the envisioned land use changes are valued. Particular attention is given to the incorporation of spatial variation in the natural environment and to addressing issues such as biodiversity impacts where reliable values are not available. Results show that the incorporation of ecosystem services and their values within analyses can substantially change decisions.     

Impacts of transportation infrastructure on single-family property values

New or long-standing public infrastructure such as highways, airports, and ports of entry (POE) can increase adjacent property values generating a value premium for private developers and adjacent property owners. States and local governments aim to determine the geographic footprint and anticipate the economic value created by transportation infrastructure proximity and accessibility since it represents an opportunity to capture some infrastructure costs. Hence, it is desirable to understand the degree of correlation between transportation infrastructure proximity and changes in real property values in a spatial context particularly when defining economic development zones where transportation investments are planned and where governments expect to recover some of the infrastructure cost from increases in real property values. This research applies geographically weighted regression (GWR) analysis to determine the geographic footprint and quantify the impacts of transportation infrastructure proximity and accessibility on real property values in El Paso, Texas using a 2013 cross-sectional data set. The presence of spatial nonstationarity and heterogeneity confirms that transportation infrastructure proximity and accessibility might generate premiums on real property values, but that such premiums are not always positive and are occasionally negative. GWR shows that benefits from a transportation facility can be capitalized by non-adjacent parcels. Finally, GWR maps can help better policy development by estimating how much value is added by infrastructure proximity and accessibility throughout particular locations.
