This paper examines the economic impact of selected farmland characteristics on the appraised value of development rights. Price elasticities are estimated for the size and location of farmland parcels, the amount of road frontage, the existence of panoramic views, and the distance to urban centers. Estimated elasticities suggest that parcel characteristics have a substantial impact on the cost of preserving farmland. For example, the per-acre cost of development rights is estimated to be 53 percent higher on farmland parcels that have a panoramic view of water than on parcels that have no water view. Similarly, the per-acre cost of development rights on a typical 25-acre farm is estimated to be 90 percent higher than on a typical 150-acre farm. Results suggest that the net social benefits obtained through farmland preservation programs may be enhanced by considering the impact of farmland characteristics on the marginal costs of purchasing development rights, when selecting among a set of candidate farms.

This chapter examines the economic impact of the diffusion of a new technology as cloud computing. This will allow firms to rent computing power and storage from service providers, and to pay on demand, with a profound impact on the cost structure of all the industries, turning some of the fixed costs in marginal costs of production. Such a change will have a substantial impact on the incentives to create new business, and through this, on: investments and macroeconomic growth, job creation in all industries and job reallocation in the ICT sector, and public finance accounts, through the direct impact on the public sector spending and the indirect one on the tax revenues. In this study, the author investigates the consequences of the diffusion of cloud computing on market structures and competition and tries to disentangle the above mentioned aspects with a particular focus on a simulation run for the European economy.

AbstractThe cost-effectiveness of sequencing pools of individuals (Pool-Seq) provides the basis for the popularity and wide-spread use of this method for many research questions, ranging from unravelling the genetic basis of complex traits to the clonal evolution of cancer cells. Because the accuracy of Pool-Seq could be affected by many potential sources of error, several studies determined, for example, the influence of the sequencing technology, the library preparation protocol, and mapping parameters. Nevertheless, the impact of the mapping tools has not yet been evaluated. Using simulated and real Pool-Seq data, we demonstrate a substantial impact of the mapping tools leading to characteristic false positives in genome-wide scans. The problem of false positives was particularly pronounced when data with different read lengths and insert sizes were compared. Out of 14 evaluated algorithms novoalign, bwa mem and clc4 are most suitable for mapping Pool-Seq data. Nevertheless, no single algorithm is sufficient for avoiding all false positives. We show that the intersection of the results of two mapping algorithms provides a simple, yet effective strategy to eliminate false positives. We propose that the implementation of a consistent Pool-seq bioinformatics pipeline building on the recommendations of this study can substantially increase the reliability of Pool-Seq results, in particular when libraries generated with different protocols are being compared.

Abstract The problem of traffic congestion incurs numerous social and economical repercussions and has thus become a central issue in every major city in the world. For this work we look at the transportation domain from a multiagent system perspective, where every driver can be seen as an autonomous decision-making agent. We explore how learning approaches can help achieve an efficient outcome, even when agents interact in a competitive environment for sharing common resources. To this end, we consider the route choice problem, where self-interested drivers need to independently learn which routes minimise their expected travel costs. Such a selfish behaviour results in the so-called user equilibrium, which is inefficient from the system’s perspective. In order to mitigate the impact of selfishness, we present Toll-based Q-learning (TQ-learning, for short). TQ-learning employs the idea of marginal-cost tolling (MCT), where each driver is charged according to the cost it imposes on others. The use of MCT leads agents to behave in a socially desirable way such that the is attainable. In contrast to previous works, however, our tolling scheme is distributed (i.e., each agent can compute its own toll), is charged a posteriori (i.e., at the end of each trip), and is fairer (i.e., agents pay exactly their marginal costs). Additionally, we provide a general formulation of the toll values for univariate, homogeneous polynomial cost functions. We present a theoretical analysis of TQ-learning, proving that it converges to a system-efficient equilibrium (i.e., an equilibrium aligned to the system optimum) in the limit. Furthermore, we perform an extensive empirical evaluation on realistic road networks to support our theoretical findings, showing that TQ-learning indeed converges to the optimum, which translates into a reduction of the congestion levels by 9.1%, on average.

Rural Amenities

We investigate what farmland preservation programs reveal about the importance of protecting different rural amenities. An extensive content analysis of the enabling legislation of various farmland protection programs suggests wide variation exists in the protection of amenities. An analysis of 27 individual Purchase of Development Rights (PDR) programs’ selection criteria suggests these programs favor preserving amenities that are jointly provided by cropland and livestock operations. These PDR selection criteria also reveal unique preferences regarding the spatial patterns of preserved agricultural lands. Variation in relative weights given to protecting most parcel characteristics in PDR programs is not easily explained by factors that characterize areas experiencing farmland losses.

<p><em>This paper empirically investigates whether there is a negative relationship between the impact of terrorism in a country and national morality. A negative relationship between terrorism and national morality is predicted to exist, because it is reasoned that, in general, greater national morality leads to higher individual and social costs of terrorism, and to lower individual and social benefits from terrorism. Given the standard neoclassical assumption of rationality, an increase in the cost benefit ratio of terrorism due to increased national morality means that, with increased national morality, individuals will rationally choose to engage in less terrorism.The paper uses cross country regression analysis on contemporary data to test these ideas. It regresses the impact of terrorism on national morality and other variables. The results of the empirics of the paper are consistent with the key theoretical hypothesis. They show that the impact of terrorism is negatively associated with national morality. </em></p>

IntroductionThe importance of patient-centered outcome (PCO) evidence is increasingly recognized, but its inclusion in Health Technology Assessment (HTA) submissions remains inconsistent. We explored the impact of PCO evidence on HTA decision-making.MethodsA framework was developed to assess the impact of PCO evidence (excluding EQ-5D) on HTA appraisals. An impact rating was determined by reviewing company, committee and Evidence Review Group (ERG) opinion. This was applied to publicly available appraisal documents (National Institute for Health and Care Excellence [NICE]: 8; Scottish Medicines Consortium [SMC]: 2) in a pilot study. The framework was then refined and applied to a larger dataset.ResultsPCO evidence had ‘substantial impact’ in 3/8 NICE and 1/2 SMC appraisals, and ‘some impact’ in those remaining. PCO evidence informed the cost-effectiveness model in 2/8 NICE and 1/2 SMC submissions, and was considered superior to EQ-5D evidence in one NICE and one SMC submission. The ERG considered PCO evidence relevant to decision-making in 5/8 NICE appraisals. PCO evidence was mentioned in guidance for 7/10 appraisals (deemed relevant in 5/10). In one assessment, committee comments were notably more favorable than ERG comments. Larger dataset analysis results provided further insights to the pilot study.ConclusionsThe framework allows a systematic approach to evaluating the impact of PCO evidence on HTA appraisals.BL, AP, DGB and NY are employees of Symmetron Ltd, which received funding from Pfizer UK in connection with the development of this manuscript.

Abstract. Introduction: Foods dense in micronutrients are generally more expensive than those with higher energy content. These cost-differentials may put low-income families at risk of diminished micronutrient intake. Objectives: We sought to determine differences in the cost for iron, folate, and choline in foods available for purchase in a low-income community when assessed for energy content and serving size. Methods: Sixty-nine foods listed in the menu plans provided by the United States Department of Agriculture (USDA) for low-income families were considered, in 10 domains. The cost and micronutrient content for-energy and per-serving of these foods were determined for the three micronutrients. Exact Kruskal-Wallis tests were used for comparisons of energy costs; Spearman rho tests for comparisons of micronutrient content. Ninety families were interviewed in a pediatric clinic to assess the impact of food cost on food selection. Results: Significant differences between domains were shown for energy density with both cost-for-energy (p < 0.001) and cost-per-serving (p < 0.05) comparisons. All three micronutrient contents were significantly correlated with cost-for-energy (p < 0.01). Both iron and choline contents were significantly correlated with cost-per-serving (p < 0.05). Of the 90 families, 38 (42 %) worried about food costs; 40 (44 %) had chosen foods of high caloric density in response to that fear, and 29 of 40 families experiencing both worry and making such food selection. Conclusion: Adjustments to USDA meal plans using cost-for-energy analysis showed differentials for both energy and micronutrients. These differentials were reduced using cost-per-serving analysis, but were not eliminated. A substantial proportion of low-income families are vulnerable to micronutrient deficiencies.

The size of international trade continues to extend rapidly from day to day as a result of the globalization process. This situation causes an increase in the economic activities of businesses in the trading area. One of the main objectives of the cost system applied in businesses is to be able to monitor the competitors and the changes that can be occured as a result of the developments in the sector. Thus, making cost accounting that is proper according to IAS / IFRS and tax legislation has become one of the strategic targets of the companies in most countries. In this respect, businesses should form their cost and pricing systems according to new regulations. Transfer pricing practice is usefull in setting the most proper price for goods that are subject to the transaction, in evaluating the performance of the responsibility centers of business, and in determining if the inter-departmental pricing system is consistent with targets of the business. The taxing powers of different countries and also the taxing powers of different institutions in a country did not overlap. Because of this reason, bringing new regulations to the tax system has become essential. The transfer pricing practice that has been incorporated into the Turkish Tax System is one of the these regulations. The transfer pricing practice which includes national and international transactions has been included in the Corporate Tax Law and Income Tax Law. The aim of this study is to analyse the impact of goods and services transfer that will occur between departments of businesses on the responsibility center and business performance, and also the impact of transfer pricing practice on the business performance on the basis of tax-related matters. As a result of the study, it can be said that transfer pricing practice has an impact on business performance in terms of both price and tax-related matters.
