Are Preferences for Environmental Quality Sensitive to Financial Funding Schemes? Evidence from a Marine Restoration Programme in the Black Sea

This paper uses a non-market valuation study to elicit consumers’ preferences for a marine restoration programme in the Black Sea aiming to reduce the level of public health risk from bathing and improve water quality and the overall level of marine biodiversity. In this context, we administer a stated choice experiment in coastal settlements in Ukraine and Turkey and employ two tax revenue reallocation schemes as payment vehicles. One proposes the financing of the marine restoration programme by the reduction of the public budget for renewable energy and the second by the reduction of the public budget on training for civil servants. We examine the stated preferences and the subsequently derived economic value estimates in the two treatments with the aim to investigate whether the trade-off implied by the funding scheme has implications for the valuation outcome. Results reveal that preferences and marginal rates of substitution between the non-price attributes under consideration differ significantly. In the civil servants’ budget reallocation scheme, the reallocation coefficient is positive, implying that ceteris paribus redistribution of public financial resources from this source is utility-enhancing. The magnitude of the results differs in the two considered countries mirroring their heterogeneity in political and cultural dimensions.Non-Market Valuation; Stated Choice Experiment, Payment Vehicle, Tax Revenues Reallocation, Marine Resources, Black Sea, Marine Biodiversity, Developing Countries

Joint Energy Efficient and QoS-aware Path Allocation and VNF Placement for Service Function Chaining

Service Function Chaining (SFC) allows the forwarding of a traffic flow along a chain of Virtual Network Functions (VNFs, e.g., IDS, firewall, and NAT). Software Defined Networking (SDN) solutions can be used to support SFC reducing the management complexity and the operational costs. One of the most critical issues for the service and network providers is the reduction of energy consumption, which should be achieved without impact to the quality of services. In this paper, we propose a novel resource (re)allocation architecture which enables energy-aware SFC for SDN-based networks. To this end, we model the problems of VNF placement, allocation of VNFs to flows, and flow routing as optimization problems. Thereafter, heuristic algorithms are proposed for the different optimization problems, in order find near-optimal solutions in acceptable times. The performance of the proposed algorithms are numerically evaluated over a real-world topology and various network traffic patterns. The results confirm that the proposed heuristic algorithms provide near optimal solutions while their execution time is applicable for real-life networks.Comment: Extended version of submitted paper - v7 - July 201

Assessing the Direct Economic Effects of Reallocating Irrigation Water to Alternative Uses: Concepts and an Application

Irrigation water reallocations are playing an increasingly important role in both developed and developing countries. With growing urban and environmental water demands, rising costs for the development of new water supplies, and irrigated agriculture usually including the least economically valuable use of water, transfers of irrigation water to alternative uses are increasing. However, such reallocations are often controversial, and it is often questioned whether the benefits resulting from these transactions are large enough to outweigh the associated costs. This paper reviews the experience with irrigation water transfers, including the involvement of the World Bank. It discusses the problems of assessing the direct economic effects of reallocations, with a focus on the foregone direct benefits in irrigated agriculture. Because foregone direct benefits cannot easily be directly observed, they need to be estimated. However, assessments have shown widely differing estimates -- even when the same methodology was used. The paper reviews the methodologies and model specifications used for estimating foregone direct benefits; illustrates the impact of different model specifications on the magnitude of estimates of foregone direct benefits based on an application in an example case; and draws conclusions with regard to future efforts in assessing reallocation effects, including calculating adequate compensation for farmers. Because estimating the direct benefits of irrigation expansion is methodologically equivalent to estimating foregone direct benefits from reduced irrigation water supplies, the findings have implications for a broader range of water allocation decisions

Pollution and the State: The Role of the Structure of Government

Government spending has significant environmental implications. This paper analyzes the effect of the allocation of government spending between public goods broadly defined and private goods or non-social subsidies on air and water pollution. The theoretical model predicts that a reallocation of expenditures from private subsidies to public goods improves environmental quality by reducing production pollution. We estimate an empirical model that shows that such a reallocation causes a significant reduction in air pollutants namely sulfur dioxide and lead and an improvement in water quality measures including dissolved oxygen and biological oxygen demand.

Markets and Growth

This paper studies key markets (financial, labor, natural resource, and product) to assess how they are facilitating or constraining growth. First, we draw on the body of existing theoretical and empirical literature to discuss the links between markets and growth. Second, we present four stylized scenarios of the process of growth, which summarize market infrastructure and efficient factor reallocation in response to shocks appear to be among the most important growth determinants. We highlight the relative lack of research on the relationship between labor markets and growth, as opposed to the relationship between human capital production and growth. Finally, we combine suggestions of Topel (1999) and Pritchett (2000) to argue that country-specific markets should be a principal focus of future research on growth. This paper provides a framework for such studies.http://deepblue.lib.umich.edu/bitstream/2027.42/39766/3/wp382.pd

Comparing Tax and Tax Reallocations Payments in Financing Rail Noise Abatement Programs: Results from a CE valuation study in Italy

The paper examines the use of choice experiments (CE) to assess the economic value of alternative rail noise reduction interventions on the so-called Brennero railway, Italy. The novelty of this paper is threefold. To our knowledge, this is the first study on the valuation of noise conducted in Italy and it is the first example of CE applied in the field of rail noise valuation. Second, we consider not only the economic value assessment of noise reduction but also how this reduction is achieved, ranging from policy instruments such as barriers or train technology. Third, the paper provides an original contribution in the valuation literature since we test formally the econometric robustness of the CE estimates under three payment vehicles. In fact, we consider (a) a special regional tax, (b) reallocation of financial resource within the provincial budget on the public transport sector, and (c) reallocation of financial resource of the provincial budget from the administration and entertainment sector. Test results are mixed. Welfare analysis and policy implications of valuing rail noise reduction programs using different payment vehicles are discussed.Choice Experiment, Noise Abatement, Tax, Tax Reallocation, Formal Testing, Welfare Analysis
