Background (2)
Literature review
 Shale gas and environmental policies:
 Main conclusion: expansion in supply of natural gas in
combination with appropriate carbon polices will help the US
economy to achieve low-carbon standards in future [Brown et
al. (2010), Paltsev (2011), Jacoby (2011)]
 Shale gas and gas exports:
 Gas export will benefit resource owners, negatively affect
energy intensive industry, and increase domestic gas prices
[NERA 2012, Deloitte 2011, Brooks (2012), Ditzel et al. (2013),
Sarica and Tyner (2013)]
 Shale gas and economic impacts:
 Shale gas will improve welfare, positively affect GDP, and
generates job and investment opportunities [IHS Global
Insight Inc (2011), Citi GPS (2012) and Arora (2013)]

Background (3)
Objective of this paper
 Exiting studies are mainly concentered on expansion in
shale gas and have ignored the fact new extraction
technologies will expand supplies of oil and gas jointly,
 They do not provide comprehensive economic and
environmental analyses,
 This paper fills the gap in this area and evaluates
economic and environmental impacts of expansion in
shale oil and gas using a global hybrid modeling
framework through 2035.

sectors,

Experiments
Three main experiments
 Experiment I: Changes in US oil and gas with no
expansion in shale resources,
 Experiment II: Changes in US oil and gas with expansion in
shale resources, while we assume no growth in crude oil
exports,
 Experiment III: Changes in US oil and gas with expansion in
shale resources, with no change in crude oil or natural gas
exports. Petroleum product exports are free to expand,
 For each experiment, we run simulations for the following 5
time segments: 2007-12, 2012-17, 2017-2022, 2022-2027,
and 2027-2035.

Conclusions (1)
 The shale oil and gas boom has a major impact on the US
economy,
 During the time period from 2008 through 2035 the US GDP on
average would be 2.2% higher than its 2007 level with the
expansion in shale resources,
 Without the expansion in shale resources on average the US GDP
will be 1.3% lower than its 2007 level during the same time
period,
 The expansion in shale resources boosts US GDP by 3.5% of its
2007 level during the time period 2008-37.
19
Conclusions (2)
 The welfare gains are also quite large,
 On average the welfare difference between the positive shock and
the negative shock is $473 bil. per year over the time period from
2008 through 2035.
 If we restrict gas exports the magnitude of the annual difference
increases to $487 billion,
 The shale boom creates substantial employment opportunities
with jobs growing on average about 1.8% in the positive shock
and declining about 1.1% in the negative shock for a net of about
+2.9% employment gains.
 All of these figures are compared with 2007.
20
Conclusions (3)
 The expansion in shale resources improves the US energy trade balance
by more than $72 billion in 2035 compared to 2007,
 With no expansion in shale resources the US net energy imports goes up
by $44 billion in 2035 compared to 2007,
 Expansion in shale resources causes a worsening in the overall trade
deficit driven by the increased level of economic activity.
 In the absence of emissions reduction policies, the expansion in shale
resources will increase CO2 by 4.1% between 2007-2035,
 Imposing a restriction on gas exports improves economic welfare but
increases CO2 emissions by 6.9%,
 The expansion in shale resources generates huge opportunities for the
US economy to grow.
