Determinants of residential water demand in Germany

We econometrically analyze the impact of several economic, environmental and social determinants for the per capita demand for water in about 600 water supply areas in Germany. Besides prices, income and household size, we consider the effects of population age, the share of wells, housing patterns, precipitation and temperature. We also explore why current per capita residential water consumption in the new federal states is about 30% lower than in the old federal states. Since average cost pricing may cause an endogeneity problem, we apply instrumental-variable procedures in addition to single equation ordinary least squares, but find no evidence that prices are endogenous. Our estimation results suggest that the price elasticity of water demand in Germany is around − 0.24. The income elasticity is positive, decreases with higher income levels and is at least three times higher in the new federal states than in the old federal states. Current differences in prices and income levels explain about one third of the gap in residential water use between the two regions. Household size and the share of wells have a negative impact on per capita water demand, and water use increases with age. Finally, the findings provide some evidence that rainfall patterns rather than total rainfall affect water consumption, while temperature appears to have no impact at all. All outcomes are robust to a log-log and two types of semi-log specifications for the water demand function.     

What triggers environmental management and innovation? Empirical evidence for Germany

It is frequently hypothesized that environmental management systems (EMSs) may improve firms' environmental innovation performance. Whether this hypothesis is true is as critical for environmental policy as questions pertaining to the relevant incentives for (1) a firm's voluntary adoption of an EMS and (2) its environmental innovation behavior. Based on ample empirical evidence for German manufacturing, this paper addresses the simultaneity of these issues on the basis of a recursive bivariate probit model that explores the hypothesis that a facility's decision on innovation activities is correlated with the decision on EMS adoption. Our empirical results, indicating that environmental innovation activities are not associated with EMS implementation nor any other single policy instrument, reflect the perceptions of the survey respondents and, hence, should be interpreted as correlations rather than causal relationships. According to these perceptions, innovation behavior seems to be mainly correlated with the stringency of environmental policy.     

Estimation of the effects of price on apartment water demand using cointegration and error correction techniques

Water price is a key instrument in regulating water demand in the residential sector. Many empirical studies have assessed the effects of price through quantifying the price elasticity of water demand. However, most of these studies have mainly focused on the single-family housing rather the multifamily housing. An in-depth understanding of the price elasticity of multifamily housing water demand is paramount for water planners in order to properly manage water use in the fast growing intensive housing developments in urban areas. This study investigates both the long-term and short-term price elasticities of water demand in the residential apartments in Auckland central city. Using 6 years of monthly time series data, the price elasticities were estimated through cointegration and error correction methods. The results showed that the price elasticities of water demand were ?0.14 and ?0.12 in the short term and the long term, respectively. The price is inelastic yet negative and statistically significant, thus it can play a role in demand management.     

An Economic Analysis of Yard Care and Synthetic Chemical Use: The Case of San Francisco

Yard care is an economically important household production activity that also has potentially significant environmental or health impacts. Of particular concern are the possible negative impacts of using synthetic pesticides and fertilizers. But economic models and empirical analyses of yard care and chemical use are rare. We develop a simple model of household production and consumption to analyze yard care and chemical use. We then estimate a multinomial logit model of these behavioral choices with household data from San Francisco. Attitudes towards the quality of one's outdoor residential environment and time scarcity are important determinants of the odds of chemical use whereas financial variables play the major role in determining the odds that people have and care for yards. These results could help to improve educational or marketing campaigns that aim to reduce potential or actual problems associated with yard chemical use. Better data for models similar to this one are needed for future research.     

Is economic rebalancing toward consumption “greener”? Evidence from visibility in China, 1984–2006

The Chinese government has adopted a rebalancing strategy since 2011, shifting from an investment- to consumption-oriented growth model. An aim of this reform is for a “greener” development mode, but relevant empirical evidence is slim. In this study, we propose an innovative methodology to shed light on the environmental externalities of economic rebalancing. First, we use air visibility across China to reflect air quality during 1984–2006. Second, with the daily visibility data, we propose a weekend-effect regression model to difference out city-specific unobserved heterogeneity. Third, we approximate local consumption intensity with the portion of the residential electricity usage in the total electricity usage. To our surprise, the estimates suggest that the pollution intensity of consumption activities has not only been significant, but also exceeded that of production since the mid-1990s. Hence, rebalancing toward consumption is not necessarily more environmentally friendly according to the recent development experience of China.     

Identifying the sources of energy use change: Multiple calibration decomposition analysis and structural decomposition analysis

Decomposition methodologies are requisite to identify the sources of changes in energy use or carbon dioxide emissions. This paper is an inquiry into the theoretical properties of such decomposition methodologies. The study first presents our new decomposition methodology – the Multiple Calibration Decomposition Analysis (MCDA) – as a tool for the investigation. Then, it theoretically reexamines an established decomposition methodology – the Structural Decomposition Analysis proposed by Casler and Rose (1998). Subsequently, the study empirically investigates the properties of both methodologies, applying them to an actual case: the changes in energy use and carbon dioxide emissions in Japan during the oil crises period, when the oil price had a significant influence on the economy. The result shows that understanding the theoretical properties of decomposition methodologies is essential for a precise interpretation of empirical results.     

Are foreign investors attracted to weak environmental regulations? Evaluating the evidence from China

At the center of the pollution haven debate is the claim that foreign investors from industrial countries are attracted to weak environment regulations in developing countries. Some recent location choice studies have found evidence of this attraction, but only for inward FDI in industrial countries. The few studies of inward FDI in developing countries have been hampered by weak measures of environmental stringency and by insufficient data to estimate variation in firm response by pollution intensity. This paper tests for pollution haven behavior by estimating the determinants of location choice for equity joint ventures (EJVs) in China. Beginning with a theoretical framework of firm production and abatement decisions, we derive and estimate a location choice model using data on a sample of EJV projects, Chinese effective levies on water pollution, and Chinese industrial pollution intensity. Results show EJVs in highly-polluting industries funded through Hong Kong, Macao, and Taiwan are attracted by weak environmental standards. In contrast, EJVs funded from non-ethnically Chinese sources are not significantly attracted by weak standards, regardless of the pollution intensity of the industry. These findings are consistent with pollution haven behavior, but not by investors from high income countries and only in industries that are highly polluting. Further investigation into differences in technology between industrial and developing country investors might shed new light on this debate.     

DETERMINANTS OF ENVIRONMENTAL NONCOMPLIANCE BY PUBLIC WATER SYSTEMS

Whereas a large number of empirical studies have been devoted to analyzing determinants of environmental compliance (EC) by firms, less attention has been paid to EC by public water systems (PWS). To address this gap in the literature, this article uses data on compliance with maximum contaminant levels (MCL) under the Safe Drinking Water Act for 971 PWS in Arizona and identifies the characteristics of PWS that are associated with violation of MCL standards. Three main findings emerge from the analysis. First, larger PWS are more likely to violate MCL standards than smaller PWS. Second, publicly owned PWS have slightly higher probability of violating MCL standards than privately owned systems. Finally, PWS serving residential areas are more likely to violate MCL standards, as opposed to PWS serving school districts or office buildings. The results suggest that for ensuring safe water for people, effectiveness of monitoring policy, and an efficient utilization of resources, the environmental agencies may focus their monitoring and enforcement efforts on these water systems.(JEL K32, Q53)     

The Determinants of Sticky Prices and Sticky Plans: Evidence from German Business Survey Data

So far, there is no consensus on the price adjustment determinants in the empirical literature. Analyzing a novel firm‐level business survey data set, we provide new insights on the price setting behavior of German retailers during a low inflation period. Relating the probability of both price and pricing plan adjustment to time‐ and state‐dependent variables, we find that state‐dependence is important; the macroeconomic environment as well as the firm‐specific condition significantly determines the timing of both actual price changes and pricing plan adjustments. Moreover, input cost changes are important determinants of price setting. Finally, price increases respond more strongly to cost shocks compared to price decreases.     

The effects of environmental taxes and quotas on the optimal timing of emission reductions under Choquet–Brownian uncertainty

The effects of two environmental policy options for the reduction of pollution emissions, i.e. taxes and non-tradable quotas, are analyzed. In contrast to the prior literature this work endogenously takes into account the level of emissions before and after the adoption of the new environmental policy. The level of emissions is determined by solving the firm's profit maximization problem under taxes and fixed quotas. We find that the optimal adoption threshold under taxes is always larger than the adoption threshold under fixed quota, even in a setting characterized by ecological uncertainty and ambiguity – in the form of Choquet–Brownian motions – on future costs and benefits over adopting environmental policies.     

CO2 emissions, research and technology transfer in China

Although the economy of China has grown very strongly over the last few decades, this spectacular performance has come at the expense of rapid environmental deterioration. Amidst animated debate on the issue of global warming, this study attempts to explore the determinants of CO₂ emissions in China using aggregate data for more than half a century. Adopting an analytical framework that combines the environmental literature with modern endogenous growth theories, the results indicate that CO₂ emissions in China are negatively related to research intensity, technology transfer and the absorptive capacity of the economy to assimilate foreign technology. Our findings also indicate that more energy use, higher income and greater trade openness tend to cause more CO₂ emissions.     

Groundwater management under heterogeneous land tenure arrangements

We develop a groundwater extraction model that considers the Marshallian inefficiency associated with sharecropping and use data from Pakistan to simulate the impact of an open access regime and of optimal management on groundwater extractions, the state of the aquifer, and annual net benefits through time. We also evaluate a price instrument as a mechanism of inducing optimal extractions. Under both open access and optimal management, we observe notable differences in groundwater extractions and the water table level between the tenure model (which considers the behavior of both owner cultivators and sharecroppers) and the baseline model (which includes the behavior of only owner cultivators). We also find a modest difference in the aggregate net benefits generated by the two models. The results offer new insights—vis-à-vis land tenure heterogeneity—into the evaluation of more effective policies for groundwater management and aquifer sustainability.     

SHEDDING LIGHT ON THE LIGHT BULB PUZZLE: THE ROLE OF ATTITUDES AND PERCEPTIONS IN THE ADOPTION OF ENERGY EFFICIENT LIGHT BULBS

Despite the potential energy savings and economic benefits associated with compact fluorescent light bulbs, their adoption by the residential sector has been limited to date. In this paper, we present a theoretical model that focuses on the agents' ability to perceive the correct cost of lighting and on the role of environmental attitudes as key determinants of the adoption decision. We use original data from Ireland to test our theoretical predictions. Our results emphasize the importance of education, information and environmental awareness in the adoption decision.     

SPACE AND TIME: A COMPETING RISKS ANALYSIS OF THE IMPACT OF PROPERTY TAXES AND ZONING RESTRICTIONS ON RESIDENTIAL DEVELOPMENT

Property taxes and zoning restrictions are prevalent tools for managing land use. We combine microlevel data on residential subdivision development from the Baltimore, Maryland, metro area from 1994 to 2007 with a competing risks model to examine how both policies influence the density and timing of residential development. Consistent with theory, we demonstrate that the impact of both policies on optimal density and timing depends on whether density and time are substitutes or complements in the profit function. Our results have important implications as they provide key empirical insights into how property taxes and zoning interact to influence development patterns.     

Shadow prices, environmental stringency, and international competitiveness

Empirical tests of the relationship between international competitiveness and the severity of environmental regulations are hampered by the lack of pollution abatement cost data for non-U.S. countries. The theory of the firm suggests that environmental stringency can be measured by the difference between a polluting input's shadow price and its market price. We make a first attempt at quantifying such a measure for two industries located in nine European OECD countries. Overall, we provide (i) a new approach to measure cross-country regulatory differences in that we use a theoretically attractive measure of industry-specific private compliance cost, and (ii) empirical estimates that are an attractive tool for researchers and policymakers who are interested in examining how economic activity is influenced by compliance costs.     

Stimulating different types of eco-innovation in the UK: Government policies and firm motivations

In this paper, we adopt a recent OECD framework and examine the role of external policy tools and internal firm specific factors for stimulating three different types of eco-innovations that range on a spectrum of lower to higher technological and environmental impacts: End-of-Pipeline Pollution Control Technologies, Integrated Cleaner Production Technologies and Environmental R&D. Using a novel firm-level dataset from a DEFRA survey, we estimate a Tobit model, which provides empirical evidence showing that these eco-innovations are motivated by different external policy tools and internal firm specific factors. Our findings indicate that End of Pipeline Technologies and Integrated Cleaner Production Technologies are mainly driven by equipment upgrade motives with a view of improving efficiency while environmental regulations are effective in stimulating the End-of-Pipeline technologies and Environmental R&D. Interestingly, alongside government induced regulations, we find that market factors, mainly motivated by cost savings, are effective in driving Environmental R&D. Finally, ISO14001 certification is effective in strengthening the positive impact of environmental management systems on both End-of-Pipeline technologies and Environmental R&D while CSR policies have no significant impact on motivating any of the eco-innovations.     

The elusive effects of trade on growth: Export diversity and economic take‐off

The hallmark of the voluminous growth determinants literature is the absence of a clear‐cut effect of trade on growth. Numerous candidate regressors have been motivated by alternative theories and tested by a multitude of empirical studies, but not one trade regressor has been robustly related to growth. In this paper, we leverage Melitz's (2003) insights regarding sectoral export dynamics and Feenstra and Kee's (2008) approach to productivity and sectoral export diversity to propose a structured approach to trade and growth determinants. Instead of relying on aggregate trade measures as previous studies have done, we examine the diversity of sectoral exports and the development of broad‐based comparative advantage as a potential growth determinant. Controlling for model uncertainty and endogeneity, we find that export diversity serves as a crucial growth determinant for low‐income countries, an effect that weakens with the level of development.     

Evaluating the carbon-macroeconomy relationship: Evidence from threshold vector error-correction and Markov-switching VAR models

This paper studies the nonlinear adjustment between industrial production and carbon prices – coined as ‘the carbon-macroeconomy relationship’ – in the EU 27. We model carbon price returns and industrial production as nonlinear and state-dependent, with dynamics depending on the sign and magnitude of past realization of returns and the growth of industrial production. Our findings show that (i) macroeconomic activity is likely to affect carbon prices with a lag, due to the specific institutional constraints of this environmental market; (ii) the joint dynamics of industrial production and carbon prices seem adequately captured by two-regime threshold vector error-correction and two-regime Markov-switching VAR models compared to linear models as main competitors. The regime-switching models proposed are profoundly checked for their economic content and statistical congruency, and are found to provide a sound statistical framework for a comprehensive analysis of the carbon-macroeconomy relationship.     

Environmental justice and enforcement of the safe drinking water act: The Arizona arsenic experience

Environmental justice is concerned with the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies. A wide variety of empirical studies have concluded that disparate-impact discrimination does in fact exist since minority and low-income communities are at disproportionate risk for environmental harm. In this paper we examine these issues in the context of enforcing the safe drinking water act (SDWA). Specifically, we focus on the association between race, income, and hazardous levels of arsenic concentration and analyze the broad equity implications of implementing the new arsenic regulation by examining the relationship between community-level exposure to arsenic and socioeconomic and demographic characteristics of the population in Arizona. The results provide no support for the contention that continued selective implementation and enforcement of the revised SDWA arsenic standard is likely to disadvantage minority or low-income groups disproportionately in Arizona.
