This study examines the role of information systems (IS) on environmental sustainability by gaining an understanding of how benefits may be realized from using IS in a green context (a particular IS, regional mesonet (RM) equipped with information- and communication-based technologies and a comprehensive information system) through the use of duel approaches: a survey (218 respondents) and a case study (six interviews of stakeholders of a RM). Our results provide evidence how IS use contributes to different goals at different levels of sustainability and advance knowledge of utilizing IS for providing actual as well as anticipated benefits to sustainability. In addition, our findings provide suggestions on how successful IS might be used to further induce actions and advance goals of environmental sustainability that can contribute to energy policy-making.

With active drilling rigs essential for replenishing oil resources depleted through production, this study examines the potential asymmetries between drilling rig trajectory (vertical, directional, and horizontal), oil prices and oil production in the U.S. within a nonlinear autoregressive distributed lag framework. Based on weekly data, the results reveal long-run symmetry with respect to oil prices irrespective of drilling rig trajectory. However, there is long-run asymmetry for oil production consistent with the capital-intensive nature of drilling and the fixed costs associated with new wells. The results also show short-run asymmetry with respect to both oil prices and oil production consistent with companies taking advantage of upturns quickly and refraining from costly shut-in, plug and abandon, or increased expenditures on improved oil recovery during downturns.

To date, considerable attention has been given to evaluating movements in crude oil and gasoline prices and in determining the significance of fundamental state variables that may influence these prices. This paper differs from the existing literature by identifying the response of the single-product gasoline-crude oil crack spread to unexpected changes in real output growth, inflation, the corporate default risk premium, and the stance of monetary policy utilizing the econometric techniques of vector autoregression and generalized impulse response analysis. The generalized impulse response method does not impose a priori restrictions as to the relative importance each of the state variables may play in the process of transmitting unexpected information from the macroeconomic variables to the crack spread. The results show the extent and the magnitude of the relationship between the crack spread being investigated and macroeconomic factors.

This study evaluates the impacts of energy markets on emerging market mutual funds (EMMFs). In particular, we investigate the volatility transmission between these funds and the oil and natural gas prices. The findings suggest significant risk spillover from the energy markets to EMMFs. Furthermore, we find a large number of EMMFs’ risk transmitting to oil prices and almost all of the EMMFs’ risk transmitting to natural gas prices. By dividing the sample into two (before and after 2008), we find the EMMFs’ influence on the oil market decreasing after this turbulent period. Our results have important implications for mutual fund managers and investors.

This study examines the degree to which the deployment of well service rigs is responsive to changes in commodity prices and operating rigs in terms of long- and short-run estimates of elasticity. Well service rigs respond more to changes in natural gas rigs than oil rigs, and more to real oil prices than to real natural gas prices. In the shorter term, the findings document that the responses of well service rigs to changes in natural gas rigs and real oil prices are highly elastic, with no significant responses to changes in natural gas prices. The error correction model reveals that the change in well service rig usage adjusts to eliminate disequilibrium in the long-run relationship that exists between rigs and commodity prices. This research shows the important role that well service rigs play in the decisions of exploration and production (E&P) companies as they respond to changes in commodity prices.

Due to the nature of oil as a depleting asset, new discoveries of proved reserves are a critical component in the ongoing operations of exploration and production companies. Economic factors such as commodity price and the cost of capital should play a role in the discovery process; however, this role may vary by type of discovery source. This article examines US annual data over the years 1977–2014 to estimate the influence of oil price and interest rate on the ratio of new reserves by source to total proved reserves, controlling for changes in production. Findings from vector autoregression (VAR) models provide evidence that reserve changes respond to economic factors and these responses differ by source of discovery.

Construction projects often require multiple years to complete and the costs of supplies, materials, and labor may increase substantially during a project’s time span. As a result, construction contracts often include an escalation clause to account for cost increases. This article examines the time-series properties of new building construction costs using several producer price indexes. Using a battery of unit root tests, we find substantial evidence that construction cost indexes are generally nonstationary. This finding has implications for the proper specification and use of these series in contract escalation clauses and their respective use in forecasting construction cost increases.

Combination of well-chosen indicators into a composite Hurricane Resiliency Index is proposed to assess and monitor hurricane resiliency level of coastal communities across geographical boundaries and the changing process over time. The index is constructed nonparametrically by assigning fixed standardization factors as weights to each of the indicators. The validation addresses the question of whether the index is representative of the resiliency dimensions of interest. Results from cross-correlation calculation and binary interaction regression model show that Hurricane Resiliency Index has the capability to broadly measure the dynamics of regional economic activities, and a higher value tends to have a greater mitigating effect over the hurricane impacts.

Oil producing exploration and production companies generate revenue from reserves which, from any given well, are depleting over time. The reserve life index measures how long reserves would last at the current production rate if there were no additions to reserves. In this study, we examine the time series behavior of the reserve life index for each of the twelve onshore oil producing districts in Texas. Specifically, we model the relationship between reserve life and the real price of oil within a nonlinear ARDL framework. Among the results, we find evidence of both long-run and short-run asymmetries in the response of reserve life to increases/decreases in real oil prices. Further, the magnitude of the effect is greater for positive changes in real oil prices than for negative changes in real oil prices. The findings are important to operators, investors and policymakers interested in sustainability.

With oil company valuations tied in part to oil well drilling to replace reserves at a rate that exceeds production, understanding the dynamic relationship between the development of oil rigs and oil production is important. This study focuses on the Bakken, Eagle Ford, Haynesville, Marcellus, Niobrara, and Permian regions, historically the six major oil producing regions in the U.S. Specifically, we apply time series econometric techniques of unit root, cointegration, and error correction modeling to examine the dynamic relationship among oil production, rig count, and crude oil prices for each of these six U.S. oil producing regions. The results of this study highlight the importance of identifying the regional variations in oil production, rig count, and crude oil prices and their interactions in both the valuation of oil firms and capital investment projects as it pertains to oil drilling activity.

This paper surveys the literature on the value of current and potentially improved hurricane forecasts from the National Hurricane Center. Research on the societal impacts of hurricanes demonstrates that forecasts are likely generating substantial benefits to society in a variety of uses, including saving lives in the U. S. and across the Carribean and Eastern Pacific, reducing the cost of evacuations, improving supply chain management, and in the transportation and energy production and distribution sectors. The existing literature, however, fails generally to quantify the benefits with rigor sufficient for an academic quality benefit-cost analysis of hurricane forecasts. The paper offers several suggestions for future research to more precisely estimate the benefits attributable to current or improved forecasts.

Hurricanes disrupt business processes and activities, energy distribution and consumption, and services of infrastructure and lead to a reallocation of resources and their uses. This research models the relationship among economic and engineering measures of the state of the built environment in order to provide insight into a region's ability to withstand and recover from a future hurricane. As such, we provide a quantitative approach to modeling and measuring a region's economic resiliency. The findings have implications for developing strategies for long‐term sustainability of economic regions.

This article examines the time-series properties of the US venture capital investments (VCI) to determine whether or not various sectors compete in the same market for venture capital funds. Using a battery of unit root tests, we find substantial evidence that VCI shares are nonstationary. Our findings are consistent with a high degree of rivalry for VCI among the different sectors.
