Abstract:
We use machine learning algorithms to construct a novel news-based index of US environmental and climate policy uncertainty (EnvPU) available on a monthly basis over the 1990-2019 period. We find that the EnvPU index spikes during the environmental spending disputes of the 1995-1996 government shutdown, in the early 2010s due the failure of the national cap-and-trade climate bill and during the Trump presidency. We examine how elevated levels of environmental policy uncertainty relate to investments in the low-carbon economy. In firm-level estimations, we find that a rise in the EnvPU index is associated with a reduced probability for cleantech startups to receive venture capital (VC) funding. In financial markets, a rise in our EnvPU index is associated with higher stock volatility for firms with above-average green revenue shares. At the macro level, shocks in our index lead to declines in the number of cleantech VC deals and higher volatility of the main benchmark clean energy exchange-traded fund. Overall, our results are consistent with the notion that policy uncertainty has adverse effects on investments for the low-carbon economy hindering progress to address the urgency of climate action.

Abstract:
We re-examine the effects of negative weather anomalies during the growing season on the decision to migrate in rural households in five sub-Saharan African countries. To this end we combine a multi-country household panel dataset with high-resolution gridded precipitation data. We find that while the effect of recent adverse weather shocks is on average modest, the cumulative effect of a persistent exposure to droughts over several years leads to a significant increase in the probability to migrate. The results show that more frequent adverse shocks can have more significant and long-lasting consequences in challenging economic environments.

Abstract:
We investigate the impact of competition between legal regimes on the number of authoritative acts and amount of fines occurring in rural Sierra Leone. We model state and traditional legal systems as competing authorities with a potential for overlap in their jurisdictions. We are interested in the sign and magnitude of the legal pluralism externality in this region of overlapping authority. We then test the model and estimate the size of the externality coefficient in the context of post-conflict Sierra Leone. Our results show a negative externality between regimes for civil disputes—that is, an increase in the cost of apprehending a person. We also show that there is a reduction in the amount of fines per dispute collected in this shared space. Overall, this indicates that a potential benefit to the local people from multiple competing regimes is a reduction in expected authoritative expropriation.

Abstract:
We examine the relationship between environmental regulation and competitiveness in China. Exploiting exogenous changes in national pollution standards for three industries—ammonia, paper and cement—we test whether environmental regulation increases industry productivity. Our results show that the strong version of the Porter hypothesis does not hold, but that regulation might reallocate productivity spatially. We show that regulated industries that are located in newly developing cities see an increase in their productivity as compared to the same industries in other cities. This means that environmental regulation is more likely to drive the spatial distribution of productivity changes than it is to drive the pace and direction of technological change.

Institution:

Abstract:
This paper uses product-level data from the UK refrigerator market to evaluate the impact of electricity prices on product innovation. Our best estimate is that a 10% increase in the electricity price reduces the average energy consumption of commercialized refrigerator models by 2%. A large share of this reduction is explained by a reduction of freezing space. We also show that the exit of energy-inefficient products contributes more to energy reduction than the launch of new energy-efficient models. These findings suggest that innovation – the development of better technologies embodied in new products – does not respond strongly to energy price variations.

Centre for International Environmental Studies, The Graduate Institute (IHEID)
Abstract:
We propose a novel theoretical framework to study how environmental regulation shapes economic development in a developing country such as China. We develop a dynamic tax competition model in which local governments, located in development zones, use variation in taxes to attract workers to their jurisdictions. Their objective is to maximize tax revenue less local health costs that are proportional to local pollution. Our main result is that competition generates a reallocation of productive factors when national regulation is introduced. Local governments in more productive regions set greater production taxes than in other regions. This makes workers and output to shift from more to less developed regions of the country.

Abstract:
Expressive law is said to induce compliance with stated principles without a price on noncompliance. We empirically assess this proposition, by attempting to dis-entangle the impacts of a legal change (a 5p charge on use of plastic bags), on individual choices. We do so by measuring both behaviours and attitudes across the first two months of the legal change, and by comparing the impacts across neighboring jurisdictions both with and without the change. Using mediation analysis, we find that the self-reported change in internal motivation explains only about 10% of the change in behaviour. Interestingly, we find that the scale of the sanction (charge) is both irrelevant (because jurisdictions without sanctions still exhibit changed behaviour) and important (because the size of the sanction signals the reasonableness of the law).

Abstract:
Are environmental regulations imposed on downstream firms effective in spurring innovation in clean technologies by upstream firms? We use a novel firm-level dataset of global scope to study whether environmental regulations have percolated up the automotive global value chain, and led to innovation (measured by patenting in abatement technologies) by suppliers at different levels of the chain. Using a Poisson estimation methodology, we find that suppliers worldwide have responded to increasingly stringent emission standards imposed on automobile manufacturers (also known as original equipment manufacturers, or OEMs) by undertaking more innovation in clean abatement technologies; additionally, we find that the smaller the gap between the average environmental regulation suppliers face from the OEMs, and that in the country where the firm is located, the more the firm innovates. In addition, we provide evidence of a spread of these positive effects of regulation on innovation, with suppliers at different upstream levels responding positively to the downstream standards. This paper has important policy implications for the design of environmental policy instruments to induce innovation in clean technologies by firms along the value chain.

Abstract:
This paper analyses how labour institutions and ethnic identity shape favouritism and discrimination among workers. We conduct an experiment with union and non-union South African mineworkers from various ethnicities. We examine in-group and out-group behaviour, emphasizing the relative ranking of these groups and their interaction. We find that unions create both in-group and out-group favouritism towards co-ethnic members and members of ethnic majorities. This favouritism is however undermined by unionised subcontract workers who experience precarious conditions. Furthermore, union members discriminate against non-unionised ethnic minorities. Finally, non-union members (primarily subcontract workers) discriminate against union members, particularly after negative shocks.

Abstract:
We look at the diffusion of seed technology among Ugandan farmers. We present a targetinput model to conceptualize the adoption decisions of a new technology in which the best use of inputs is unknown. In this framework, there is path dependency in the adoption process. We show that the group of innovators is well-defined but too small to overcome the system’s inertia. We find little evidence that seed policy reforms implemented in Uganda in the past 20 years boosted agricultural productivity, largely on account of a lack of local experimentation and inadequate use and diffusion of new seed varieties.

11. The Impact of Green Innovation on Energy Intensity: An Empirical Analysis for 14 Industrial Sectors in OECD Countries

Abstract:
This paper analyses the impact of green innovation on energy intensity in a set of 14 industrial sectors in 17 OECD countries over the 1975-2005 period. We create a stock of green patents for each industrial sector and estimates a translog cost function to measure the impact of green innovation on energy intensity, next to other factors such as input substitution and autonomous technical change. We find that green innovation has contributed to the decline in energy intensity in the majority of sectors: the median elasticity of energy intensity with respect to green patenting is estimated at -0.03 in our sample. Hence, a 1% increase in green patenting activities in a given sector is associated with a 0.03% decline in energy intensity. The magnitude of the effect is larger in energy-intensive sectors and in more recent years. We also find that the impact of an additional green patent on energy intensity is larger than an average non-green patent. Our results are robust to alternative definitions of patents.

12. Environmental Regulations and Competitiveness: Evidence based on Chinese firm data

Content Type:
Working Paper
Institution:
Centre for International Environmental Studies, The Graduate Institute (IHEID)
Abstract:
This paper provides empirical evidence in support of the Porter hypothesis that tighter environmental regulations can increase productivity under certain circumstances. It builds on a theoretical model in which environmental regulations induce firms to adopt more efficient technologies. Using Chinese firm-level data covering a ten-year period, the empirical study examines the effects of two specific policy instruments - the pollution levy and regulatory standards - on firm productivity. It finds a bell-shaped relationship between pollution levies and the total factor productivity of firms, indicating that an increase in the pollution levy rate can be associated with higher productivity. In addition, the study investigates the effect of pollution emission standards on firm productivity and identifies an initial negative effect which diminishes after a period of two to three years.

Abstract:
Why give aid to resource-rich autocrats? We find that the interaction between natural resources and most forms of international aid results in enhanced political instability in most autocratic countries. Interestingly, some types of government aid (notably humanitarian aid) do not have this effect, indicating that the impact of aid varies with its form. Furthermore, we find that only aid structured in the form of loans (rather than grants) is more likely to flow toward resource-rich autocracies. This combination of loans with any political instability they may induce, can create speculative rights (for the donor) in the resource-riches of the recipient country. This potential claim on resources provides one important strategic reason to give aid to resource-rich autocrats. Aid can act as a form of foreign intervention in the pursuit of regime change, and claims on resources.

14. Using discrete choice experiments to regulate the provision of water services: Do status quo choices reflect preferences?

Author:

Publication Date:

Content Type:
Working Paper
Institution:

Abstract:
Discrete choice experiments (DCE) are increasingly used to quantify the demand for improvements to services provided by regulated utility companies and inform price controls. This form of preference elicitation, however, often reveals a high frequency of status quo (SQ) choices. This may signal an unwillingness of respondents to evaluate the proposed trade-offs in service levels, questioning the welfare theoretic interpretation of observed choices and the validity of the approach for regulatory purposes. Using the methodology for DCE in the regulation of water and sewerage services in England and Wales, our paper contributes to the understanding of SQ choices in several novel dimensions. First, we control for the perception of the SQ and the importance of attributes in day-to-day activities. Second, we use a split sample design to vary both the description of the SQ and the survey administration mode (online vs. in-person). Third, the service attributes can both improve or deteriorate, so that the SQ is not necessarily the least-cost option. Fourth, we examine SQ choices in individual choice tasks and across all tasks so as to identify the determinants of serial SQ choices. Our results suggest that individual SQ choices mostly reflect preferences and thus represent important information for the regulator. However, serial SQ choices are mainly driven by cognitive and/or contextual factors, and these responses should be analysed as part of standard validity tests.

Abstract:
Using a dual-market sorting model of workers’ location decisions, this paper studies the capitalization of air pollution in wages and property prices across Chinese cities. We exploit quasi-experimental variations in particulate matter (PM10) concentration induced by a policy subsidizing coal-based winter heating in northern China, specifying a regression discontinuity design based on cities’ location relative to the policy boundary. We estimate that the elasticity of wages and house prices with respect to PM10 concentration is 0.41 and -0.71 respectively. Our results are robust to the use of an alternative source of exogenous variation in PM10 concentration (sandstorms), supporting the view that the local effect we measure provides policy-relevant information on the value of air quality improvements in China.

16. Emissions Trading in the Presence of Price-Regulated Polluting Firms: How Costly Are Free Allowances?

Author:

Publication Date:

Content Type:
Working Paper
Institution:
Centre for International Environmental Studies, The Graduate Institute (IHEID)
Abstract:
We study whether to auction or to freely distribute emissions allowances when some firms participating in emissions trading are subject to price regulation. We show that free allowances allocated to price-regulated firms effectively act as a subsidy to output, distort consumer choices, and generally induce higher output and emissions by price-regulated firms. This provides a cost-effectiveness argument for an auction-based allocation of allowances (or equivalently an emissions tax). For real-world economies such as the Unites States, in which about 20 percent of total carbon dioxide emissions are generated by price-regulated electricity producers, our quantitative analysis suggests that free allowances increase economy-wide welfare costs of the policy by 40-80 percent relative to an auction. Given large disparities in regional welfare impacts, we show that the inefficiencies are mainly driven by the emissions intensity of electricity producers in regions with a high degree of price regulation.

Abstract:
This paper explores international productivity patterns in agriculture. We test whether countries higher productivity growth has been experienced by countries that were initially further from the technological frontier. Based on a panel of 84 countries at various levels of development, we find support for convergence among OECD countries but divergence in our sample at large over the period 1960-2010. We then test whether technological catch-up is conditional on absorptive capacities and domestic investments in R&D. While agricultural research intensity has a significant effect on labor productivity growth, the size of this effect decreases the further the country is from the frontier. We calculate a threshold level for the effectiveness of research intensity: increased R&D contributes to catching up to the frontier for those countries with a distance to the frontier less than 22. We also test for additional factors affecting productivity growth, and find that secondary education plays a strong role in less developed countries, while trade openness appears to have had a positive effect on productivity in middle income countries. On the other hand, there is little evidence of much effect, either positive or negative from IPR protection. Of perhaps greater interest is the apparent impact of economic growth outside of agriculture in driving agricultural productivity improvements.

18. Avertive expenditures, endogenous quality perception, and the demand for non-market goods: An instrumental variable approach

Author:
Bruno Lanz
Publication Date:
08-2015
Content Type:
Working Paper
Institution:
Centre for International Environmental Studies, The Graduate Institute (IHEID)
Abstract:
In response to the perceived quality of a non-market good, households may choose to incur avertive expenditures as a substitute to its aggregate provision, thereby revealing an (inverse) demand function. When unobserved heterogeneity affects both perceived quality and avertive behavior, identification is plagued by a problem of endogeneity. In this paper, I propose to use a first stage model of perceived quality as a function of objective quality to address the endogeneity problem. The exclusion restriction is theoretically motivated, and requires people to have well-formed perceptions of the quality of the good. Moreover, the first stage quantifies the relationship between perceived and objective quality measures, so that this approach can provide micro-consistent marginal willingness to pay estimates for changes in the policy-relevant objective level of provision. As an illustration, I employ data on avertive expenditures for two qualitative aspects of household tap water supply: water hardness and aesthetic quality in terms of taste and odor.

Abstract:
We examine the effect of the introduction of uniform water-charging for aquifer management and provide evidence using a survey-based choice experiment of agricultural water users in rural Tunisia. Theoretically, we show that the implementation of the proposed second-best regulation would result both in efficiency gains and in distributional effects in favour of small landholders. Empirically, we find that resistance to the introduction of an effective water-charging regime is greatest amongst the largest landholders. Resistance to the regulation of common resources may be rooted in the manner in which heterogeneity might determine the distributional impact of different management regimes.

20. Multinational Firms and the Internationalization of Green R&D: A Review of the Evidence and Policy Implications

Author:

Content Type:

Institution:

Abstract:
This paper presents novel empirical evidence on the internationalization of green R&D by multinational firms (MNCs), as measured by patents data. Using data on inventors’ addresses for the set of 1,200 MNCs firms patenting in green technologies over the 2004-2009 period, we find that about 17% of green patents result from MNCs R&D investments conducted outside their home countries. MNCs tend to locate their foreign green R&D activities in other OECD markets and in China, in particular in lightings and solar technologies. The empirical analysis reveals that the probability of conducting green R&D abroad increases with the host country’s stringency of environmental regulation, market size and (green) R&D intensity. Also, relatively lower wages for scientists and engineers, and stronger protection for intellectual property rights in the host country increase the likelihood for MNCs to offshore green R&D. The paper concludes by discussing the policy implications of this changing global innovation landscape.
