The present study examines the assumptions, modeling structure, and results of DICE-2023, the revised Dynamic Integrated Model of Climate and the Economy (DICE), updated to 2023. The revision contains major changes in the treatment of risk, the carbon and climate modules, the treatment of nonindustrial greenhouse gases, discount rates, as well as updates on all the major components. Noteworthy changes are a significant reduction in the target for the optimal (cost-beneficial) temperature path, a lower cost of reaching the 2 °C target, an analysis of the impact of the Paris Accord, and a major increase in the estimated social cost of carbon.

Residential owned solar panels mounted on roof-tops generated 1.4% of the U.S. electricity supply in 2022. Utilities compensate residential customers using a net metering system by which each kilowatt-hour generated by the customer reduces the customer's bill by the amount the utility charges for one kilowatt. Despite the small impact of roof-top solar on the total market, in 2022, thirty-two states conducted ninety-four proceedings investigating whether to change the net metering system. In these proceedings, utilities advocated changing the rates to discourage residential investment in solar panels. Utilities argue that net metering provides a subsidy to solar customers because the rate the utility pays is greater than the avoided cost of energy. That excess payment allows solar customers to avoid paying for the distribution network. The cost of the distribution network is shifted to non-solar customers. This article will evaluate these claims. It will show that if the social cost of carbon were in the calculation, it would generate a Kapp cost shift from solar customers to non-solar customers. The size of the Kapp cost shift is greater than the cost of distribution networks, reversing any private cost shift that utilities have estimated. [ABSTRACT FROM AUTHOR]

This study is a critical review of locus's paper (١٩٩٠) on internationalcapital mobility. The key question that he addresses is:" Why doescapital not flow from rich to poor countries?" The author deals withthe subject by critically reviewing Lucas's work, and his choice ofmodel and analytical objective, and tries to investigate crudely thenecessary issues which were either neglected or did not receive dueattention, such as: reverse human capital, inconsistent rules andregulations, and high investment risks in poor countries.Finally, in addition to the concluded remarks, primary suggestionsare made with respect to reduction of political risk, development andapplication of proper rules to prevent money laundering and financialcorruption…

Sustainability measurement in economics includes assessment of environmental and economic effects in an integrated manner. In this study, system level economic data are integrated with environmental impacts determined from a life cycle assessment (LCA) of a common product. We adopt a costing methodology that captures conventional costs, but additionally incorporates externality costs to present a convenient, easily interpretable metric. Green Net Value Added (GNVA) is a type of full cost accounting that incorporates total revenue, the cost of production, depreciation, and environmental externalities. We present externality costs disaggregated by upstream sectors, full cost of production, and GNVA to evaluate the relative sustainability of Bounty ® paper towels manufactured at two production facilities. We found that the longer running, more established line had a higher GNVA. The predominant components contributing to externality costs come from the stationary sources in the supply chain: electricity generation (27–35%), refineries (20–21%), pulp and paper making (15–23%). Health-related externalities from Particulate Matter (PM2.5) and Carbon Dioxide equivalent (CO2e) emissions are to a great extent driven by electricity usage and emissions by the facilities, followed by pulp processing and transport. Supply chains for other facility purchases, product distribution, and end-of-life management contribute the least to the environmental health-related costs. [ABSTRACT FROM AUTHOR]

This study aims to explore the structure of the households' social capital of rural Vietnam households with secondary data from 2008 to 2018. This paper applied the fundamental theories (resource and network theories) and the Bayesian network to estimate the interaction of proxies to explore the structure of social capital. Results showed that the triangle structure in household social capital with the core point is organization participation. The connections show the tendency from organization participation, linking to household networks. Alongside that, linking social capital and Organization participation are determinants of social capital indicators (social events, social cost). Therefore, this paper suggests employing proxies such as structured indicators for integrating social capital into the livelihood papers. [ABSTRACT FROM AUTHOR]

This paper examines big data analytics implications on the central banking financial system's technological progress. A digital technological progress framework and model is established to analyze the economy's aggregate supply via covering the monetary policy, big data analytics, pollutants emissions as independent variables and the economy's aggregate demand as a moderating variable in a modified extensive growth theory framework and model to compute the productivity indicators and the total factor productivity (TFP) as the central banking technological progress that combined the mentioned variables qualities contribution. Besides, data analytics positive and negative externalities that include data analytics shortcomings as unpriced undesirable output in the form of cybersecurity and pollutants' emissions among other proxies are internalized in the framework and the model to integrate the digital technology innovation with digital technology shortcomings and climate change. This revised extensive theory framework and model is a remarkable technique comprehensive of the technological progress matters and sustainable economic development and is considered one of the most important sustainable development and long-run economic growth proportions in the central banking financial system functions to manage the economy's aggregate supply and demand that unnoticed by previous studies.

The increased usage of navigation technologies has caused conflicts in local traffic management, resulting in congested residential areas among other challenges for residents. This paper uses content analysis to investigate such negative social externalities within local communities and neighbourhoods. Through a corpus of 90 news articles about traffic incidents caused by navigation technologies, we identified negative traffic and safety-related externalities, including congestion, damage, pollution, and accidents. We also report on countermeasures by local communities and governments, including street closures, speed limit reduction, and turn bans. Based on our results, we discuss the implications for designing mobile navigation technologies that reduce negative social externalities. [ABSTRACT FROM AUTHOR]

Platforms are a dominant model for coordinating complex economic interactions. Platforms are distinguished by growth through network effects: an increase in the number (N) of platform actors (or complements produced by them) on one side makes the platform more valuable for an actor on the same or other side (and vice versa). This paper unbundles the network effect—the feedback loop—into directional and distinct types of network externalities that define the value received by each platform side. For example, value from a network externality may relate to variety (e.g., Google Play apps) or availability (e.g., Uber rides). Furthermore, at times, network externalities can have a negative impact. Although the existing literature recognizes some of these constituents, we lack an integrative framework. To address this gap, we first distinguish the heterogeneity and persistence of platform value units to identify a 2 × 2 typology of four positive and negative network externalities: quantity versus rivalry, accumulation versus fragmentation, variety versus choice overload, and utility versus degradation. Second, we generalize network connectivity and horizontal complementarity as two types of network externality amplification. Third, we demonstrate how all these dynamics play together in interactions that ultimately underscore the platformvalue and growth. [ABSTRACT FROM AUTHOR]

This paper investigates Samuelson's [Samuelson, P. A. 'Where Ricardo and Mill Rebut and Confirm Arguments of Mainstream Economists Supporting Globalization.' Journal of Economic Perspectives, 18(3), 2004, 135-46] argument that technical progress of the trade partner may hurt the home country. We illustrate this prospect in a simple Ricardian model for situations with outward knowledge spillovers. Within this framework Samuelson's Act II effects may occur. Based on industry level panel data for 17 OECD countries for the period 1973-2000 we show econometrically that the outflow of domestic knowledge via exports or foreign direct investment (FDI) to the rest of the world may have a negative impact on industry output in the home country. This is particularly so when exporting to technologically less advanced countries and, more specifically, China. ( JEL F10, F11, F14, O30) [ABSTRACT FROM AUTHOR]

Using daily data since 2017, we disentangle China-specific structural shocks driving Chinese financial markets and examine spillovers across global markets. The novelty of this paper consists of simultaneously identifying China shocks with shocks emanating from the United States and shocks to global risk sentiment - two major forces driving global financial markets - to ensure that China spillover estimates do not reflect common factors. Our results show that shocks originating in China have material impacts on global equity markets, although spillovers are much smaller than those following shocks in the United States, or those triggered by shifts in global risk sentiment. By contrast, shocks from China account for a significant proportion of variation in global commodity prices, more on a par with those of the United States. Nevertheless, spillovers from China can be significantly amplified in an environment of heightened global volatility, or when the shocks are large. [ABSTRACT FROM AUTHOR]

Purpose: This paper aims to propose a methodology for assessing an optimal portfolio of investment instruments that minimise the social costs of decarbonising economic activity while improving the environmental objectives proposed in EU legislation. Design/methodology/approach: The methodology defines the net social cost of decarbonisation related to a portfolio of four instruments: installation of solar PV and wind generation, thermal insulation of households and deployment of heat pumps. The social cost is minimised by restricting it to the minimum level of the targets proposed in the Spanish National Energy and Climate Plan to reduce greenhouse gas emissions, increase generation from renewable sources and reduce energy consumption. The empirical approach also includes differences between regions according to the expected effect for instruments. Findings: The application of this methodology to the environmental objectives defined in the current Spanish National Energy and Climate Plan for 2030 concludes that it is clearly possible to reduce the social cost of decarbonisation while improving environmental performance through a reorientation of investment instruments. In this case, such a reorientation would be based on a minimisation of efforts in thermal insulation of households and a maximisation of measures aimed at the installation of heat pumps. Originality/value: The paper proposes a novel methodology for a social cost assessment that improves the allocation of a portfolio of environmental instruments. This portfolio could be extended in further work to include instruments related to transport or support for industrial decarbonisation, such as the deployment of renewable hydrogen, among others.

The rapid growth of on-demand ride service platforms has made it increasingly important for these platforms to efficiently match services by understanding driver characteristics and consumer preferences. This paper aims to investigate the pricing strategy by considering the impact of consumer preference heterogeneity and the different service types offered by drivers. The findings of this study reveal the need for the platform to strike a balance between service cost and the benefits of high-quality drivers, which can be referred to as the "cost-performance ratio". If the "cost-performance ratio" that attracts high-quality drivers is high, the platform will attract high-quality drivers or drivers of all types to participate while offering differentiated services. Otherwise, the platform will only provide services through low-quality drivers. Furthermore, the platform will also consider when to offer differentiated services based on network externalities and service quality. When the network externalities of the two types of services are similar, the platform will differentiate them based on service quality differences. Overall, considering consumer preference heterogeneity, drivers of service types, and network externalities, this paper provides guidance for platforms to make optimal decisions that enhance their service offerings and improve overall customer satisfaction.

An important share of the social housing stock in Flanders is outdated, resulting in a high energy demand for heating. Energetic renovation is hence urgently needed. The current economic model, however, does not stimulate this due to a split incentive. As energy prices have increased in the past few years, more tenants have suffered from energy poverty. This paper investigates three alternative economic models aiming at increasing the incentive for renovation, while financially protecting the tenants. In the first alternative model, tenants are protected by inducing a maximal cost of living based on their income. In the second alternative model, a fixed rent is applied, while the third alternative model proposes to share the cost benefits of the energetic renovation. The paper analyses the alternative models by assessing the costs and income for social housing companies and the costs for tenants for an unrenovated building, a renovation with a low investment cost and a deep energetic renovation. The results show that limiting the cost of living based on income seems most interesting as this is beneficial for the tenants and gives an incentive for the social housing companies to renovate. To reduce energy poverty, a deep renovation is necessary. [ABSTRACT FROM AUTHOR]

The objective of this research was to determine whether willingness to bear the negative externality from water quality impairment differs between those who do and those who do not receive economic benefit from the impairment source. Differences were tested using a hedonic analysis of ambient water quality in two discrete housing markets in the Pigeon River Watershed, which have been polluted by the operation of a paper mill. The results suggest that North Carolina residents residing in subwatersheds with impaired portions of the Pigeon River, who experience economic benefit from the paper mill in addition to its harmful effects on water quality, do perceive the pollution as a negative externality. In contrast, the effects of both the degraded river and its contributing streams on property values are perceived as negative externalities by watershed residents in Tennessee who experience only harmful effects from the pollution. Differences in willingness to bear the water-impairment externality were not indicated by variables representing view of and proximity to impaired water bodies. The results suggest that the perception of water quality to which property owners implicitly apply value should be considered when establishing water-quality regulations. [Copyright &y& Elsevier]

In the ongoing debate about the feasibility of enforcing a transition to decentralized energy conversion systems, arguments are often presented that lack scientific rigor. Granted, the issue is multi-faceted and fundamentally multi-disciplinary, and possible solutions strongly depend on the selection of location as well as on local climate and demographics. Furthermore, decentralizing the final energy distribution leads to potential socio-economic considerations that involve value judgements. However, the most serious problem is that media have appropriated the topic and are often publishing opinion papers authored by non-specialists and even by representatives of interest groups. The present paper proposes an approach that is innovative on two counts: first, it treats "final energy" as any other commodity and therefore expands the field of investigation to the problems arising from the decentralization of a generic production line or technological chain; second, it argues that a method solidly rooted in Thermodynamics, the Extended Exergy Accounting, may be used to quantify the total amount of primary exergy resources requested by a decentralized strategy (as opposed to a centralized one), so that a comparison can be performed and discussed on a rational, unbiased and scientific basis. This is an introductory paper that reports some theoretical results of the method: realistic applications are perforce excluded because the idea is that the procedure must be drafted in such a way to be applicable to different socio-economic scenarios and locations and to remain valid under a broad range of boundary conditions.

Food reserve is the cornerstone of national strategic security. China strives to build a complementary reserve system between government and enterprises, and how to improve the efficiency of food reserves is a matter of great concern to the government and society. Based on the analysis of the connotation of food reserve efficiency, this paper constructs the revenue function and the cost function of food reserve in an emergency and uses the cost-benefit method to explore the best ratio of government reserve, corporate social responsibility reserve, and commercial inventory when maximizing the efficiency of food reserve. This ratio is closely related to the total food reserve, the scale of supply interruption, the reserve cost of food stored by enterprises, and the government's subsidy cost for the social responsibility reserve. The unit subsidy cost of government to social responsibility reserve is inversely proportional to the proportion of corporate social responsibility reserve to corporate reserve. Doing a good job in the social responsibility management of food enterprises is an effective way to improve the efficiency of food reserves. To expand the scale of social responsibility reserves and realize "storing food in enterprises," the subsidies given by the government for corporate social responsibility reserves should not be too high. Taking food social responsibility reserve as an important part of corporate social responsibility, it's the key to promoting enterprises to actively undertake food social responsibility reserves. The conclusion of this paper provides a theoretical basis and decision-making reference for how to improve the efficiency of food reserves. [ABSTRACT FROM AUTHOR]

The high-quality development of tourism aims to improve tourists’ sense of well-being and fulfillment. The improvement of tourists’ sense of well-being will not only enable tourists to obtain positive emotional experiences but is also an important way to improve their quality of life. However, the existing research has not yet reached a clear conclusion on how tourists’ sense of well-being is formed, whether tourists’ sense of well-being will spill over (i.e., knowledge sharing) after tourists obtain it, and whether the destination familiarity brought by the spillover of sense of well-being (i.e., knowledge sharing) will affect other tourists. Therefore, based on the experience marketing theory and the embodiment theory, this paper empirically examines the formation and spillover effect of tourists’ sense of well-being through structural equation modeling (SEM). The research shows that: (a) Subject presence has a positive effect on tourists’ sense of well-being, which further promotes knowledge sharing and realizes the spillover of tourists’ sense of well-being, and tourists’ sense of well-being plays a mediating role between subject presence and knowledge sharing; (b) Destination familiarity resulting from the spillover of sense of wellbeing (i.e., knowledge sharing) plays a negative moderating role in the positive impact of subject presence on tourists’ sense of well-being. This paper not only expands the boundaries of research on tourists’ sense of well-being and embodiment theory to some extent but also provides theoretical support and countermeasures for the high-quality development of China’s tourism and even service industry.

Abstract: This exercise examines the possibility of using shadow prices to calculate transfer prices between divisions of the multi-division or conglomerate firm and of basing divisional profit statements on transfer prices derived in this way. In order to demonstrate the proposal, a well known Harvard Buisiness School case is modified in two ways so that two different linear programming solutions can be derived. Divisional income statements are then computed which indeed do exactly distribute the total profit of the firm each time, but these statements are found to have several unsatisfactory features for purposes of income determination. The exercise concludes by suggesting extensions for study and problem solving for the student. [ABSTRACT FROM AUTHOR]

The author comments on the paper "Economies of Scale of Financial Institution," by George Benston published in the May 1972 issue of the "Journal of Money, Credit and Banking." It is the author's goal to sharpen Benston's research, and to do so, several questions are presented regarding his study. The author explains that Benston ignores externalities, but he does mention externalities in bank costs. The author also questions why Benston does not present a discussion on costs of capital employed in banking.

This paper studied the impact of high-speed railway linesonagricultural outputin the regions along their routes. It also investigated the heterogeneity of this impactbased on the terrain characteristics. The results of empirical testsusing county-level data show that ahigh-speed railway line can bring higher agricultural "dividends" to counties along the line. Notably, low altitude areas and regionswith gentle terrain exhibit a more pronounced promotional effect on local agricultural output. High-speed railways mainly promote agricultural output by promoting the mechanization of agriculture in counties along the route, thus reinvigorating the agricultural population and the development of specialty agriculture. Ourfindingsprovide quasi-microscopic evidence of the potential benefits of transportation infrastructure construction to break down geographical barriers and facilitate production factor flow, and providesa theoretical basis for the economic spillover effects of high-speed railway construction.

This paper provides a brief overview of China's capital controls, external asset holdings and the real interest rate, and analyzes the quantitative effects of China's macroeconomic policies between 2000 and 2015, including capital controls, interest rate policy, exchange rate policy and fiscal policy, on the dynamics of China's trade balance vis-a-vis the United States and the world real interest rate. In my analysis, I take into account the demographic differences between the countries, which affect the external imbalances directly and indirectly by affecting the transmission of the macroeconomic policies. Capital controls in China remain stringent even though they have somewhat eased in 2010s, and its gross external asset holdings differ from its peer countries both in terms of the largest functional categories and by type of investment. The average interest rate spread with the US has narrowed down. According to my analysis, the macroeconomic policies overall, and mainly the undervaluation of the real exchange rate, have had a positive impact on China's trade balance. The impact of the macroeconomic policies on the real interest rate has been positive, countering the negative trend induced by demographic factors. [ABSTRACT FROM AUTHOR]

Interactions between people and large carnivores on shared landscapes can have harmful social and ecological consequences. Human–carnivore coexistence depends on an assemblage of sociological factors including effective management institutions that address the social costs of carnivore conservation and promote tolerance toward wildlife. In East Africa, large carnivores are particularly troublesome for herders who depend on livestock for subsistence and wellbeing. This paper provides an overview of human–hyena conflict in the Tarangire ecosystem of northern Tanzania. It presents descriptive results from a questionnaire survey (n = 1076) administered as part of an anthropological study (2019–2020; 2022; 2023) of human–wildlife interactions across twelve villages inhabited by Maasai agropastoralists. The survey instrument was designed through community-based participatory research methods to convey herder concerns about the impacts of spotted hyenas (Crocuta crocuta) on the livestock economy. Based on the perceptions and local ecological knowledge of Maasai interlocutors, the paper provides an overview of the spatial and temporal patterns of human–hyena interactions. Perceived frequencies of hyena attacks on kraaled livestock were unevenly distributed geographically, with those homesteads surrounding Manyara Ranch most heavily affected. Based on herder-reported livestock losses, the costs of depredation by spotted hyenas across the study area were estimated at approximately USD 904.84 per household per year. Most homesteads lacked fortified bomas and would benefit from the provision of lights and fencing materials to improve kraal structures. The paper's central finding is that spotted hyenas represent a pressing, everyday concern for local pastoralists. Unsurprisingly, herders despise hyenas and are intolerant of sharing landscapes with them. For carnivore conservation outside protected areas to thrive in Tanzania, conservationists and policy makers must engage more meaningfully with the lived experiences of local herders who bear the brunt of conservation costs on their livelihoods.

This paper tackles the challenges inherent in crowdsourcing dynamics by introducing the CROWDMATCH mechanism. Aimed at enabling crowdworkers to strategically select suitable crowdsourcers while contributing information to crowdsourcing tasks, CROWDMATCH considers incentives, information availability and cost, and the decisions of fellow crowdworkers to model the utility functions for both the crowdworkers and the crowdsourcers. Specifically, the paper presents an initial Approximate CROWDMATCH mechanism grounded in matching theory principles, eliminating externalities from crowdworkers' decisions and enabling each entity to maximize its utility. Subsequently, the Accurate CROWDMATCH mechanism is introduced, which is initiated by the outcome of the Approximate CROWDMATCH mechanism, and coalition game-theoretic principles are employed to refine the matching process by accounting for externalities. The paper's contributions include the introduction of the CROWDMATCH system model, the development of both Approximate and Accurate CROWDMATCH mechanisms, and a demonstration of their superior performance through comprehensive simulation results. The mechanisms' scalability in large-scale crowdsourcing systems and operational advantages are highlighted, distinguishing them from existing methods and highlighting their efficacy in empowering crowdworkers in crowdsourcer selection.

This paper studies a novel social commerce practice known as "help-and-haggle," whereby an online consumer can ask friends to help her "haggle" over the price of a product. Each time a friend agrees to help, the price is cut by a random amount, and if the consumer cuts the product price down to zero within a time limit, she will get the product for free; otherwise, the product reverts to the original price. Help-and-haggle enables the firm to promote its product and boost its social reach as consumers effectively refer their friends to the firm. We model the consumer's dynamic referral behavior in help-and-haggle and provide prescriptive guidance on how the firm should randomize price cuts. Our results are as follows. First, contrary to conventional wisdom, the firm should not always reduce the (realized) price-cut amount if referrals are less costly for the consumer. In fact, the minimum number of successful referrals the consumer must make to have a chance to win the product can be nonmonotone in referral cost. Second, relative to the deterministic price-cut benchmark, a random price-cut scheme improves firm payoff, extracts more consumer surplus, and widens social reach. Additionally, in most instances, it also reduces the promotion expense while increasing profit from product sales at the same time. Third, help-and-haggle can be more cost effective in social reach than a reward-per-referral program that offers a cash reward for each successful referral. However, using the prospect of a free product to attract referrals cannibalizes product sales, potentially causing help-and-haggle to fall short. Yet, if consumers are heterogeneous in product valuations and referral costs or face increasing marginal referral costs, help-and-haggle can outperform the reward-per-referral program.

With growing awareness of the environmental, economic, and social costs associated with food waste, there is a concerted effort on multiple scales to recover the nutrient value of discarded food. These developments are positive, but the rapid movement toward alternatives and the complexity of solving problems located at the intersection of economic, social, and environmental systems also have the potential to produce unanticipated risks. This paper draws upon long-term stakeholder-engaged research throughout New England, with a focus on Maine, to develop a transdisciplinary, systems-based model of the potential social, economic, and environmental risks of food waste nutrient cycling. Our effort is intended to help inform the creation of safe, functional, and environmentally benign circular food systems. [ABSTRACT FROM AUTHOR]

The concept of social capital has gained significant attention in recent years due to its potential for improving individual and collective well-being, and for its significance in shaping social, economic, and political structures. This study aims to measure the social capital of rural Vietnam households with data from 2008 to 2016. The authors identified different aspects of household social capital as well as social capital proxies from livelihood papers. This paper applied the fundamental theories (the resource theories and network theories to measure the household social capital in Vietnam. We propose to apply the MIMIC model (multiple indicator multiple cause model) to construct the household social capital along with integrating the indicators in both views of household social capital. Results highlight the importance of understanding the multifaceted nature of social capital, which includes different forms of social networks, social participation, and social costs. The findings suggest that participation in diverse organizations plays a vital role in the formation of household social capital. In addition, the MIMIC model shows that participation in social networks is the most important factor in the formation of household social capital. Therefore, we give some implications for the measurement as well as characteristics in the social capital of households in Vietnam. The study contributes to the existing literature on social capital by emphasizing the importance of understanding the different aspects of social capital and how they interact with each other in shaping the livelihoods of rural Vietnamese households.

The purpose of this paper is to contribute to the theoretical discussion on the best way to define Corporate Social Responsibility. The methodology used is a bibliographic review through a search for articles in different catalogues (Redalyc, Ebsco, JStor, SAGE, Science Direct, and Springer), focusing on articles that addressed the study of definitions of this concept. The different ways of defining it are identified and analysed in order to find a definition can encompass all the others. The paper also proposes that locating this concept at the level of management philosophy (and not simply as a desirable or expected behaviour) facilitates the construction of agreements around a consensual definition, unlike under the predominant behavioural approach of its conceptualisation as corporate behaviour. The paper concludes by proposing to define Corporate Social Responsibility as a management philosophy based on the responsible management of the company's operational externalities on stakeholders, society, and the environment. It is concluded that this definition contributes to the theoretical discussion, strengthens empirical research, and improves the application of Corporate Social Responsibility in the corporate world.

With the change of climate issues and the needs of economic development, the idea of practicing green and low-carbon behaviors sinks deeper and deeper into people's hearts. This paper based on the social cost of carbon (SCC) model, this paper constructs a new carbon social cost model by adding the impact of green low-carbon behavior. Classify climate states, based on Bayesian statistical knowledge, study the posterior probability distribution of climate state transitions, and discuss the optimal carbon policy for different climate states by balancing emission utility costs and utility weighted carbon marginal products. This article also discusses the damage caused by rising temperatures and explores their impact on carbon price policies. then, the paper calculates SCC under four kinds of climate states, which will be visually displayed with graphs. Finally, we compare SCC obtained in this paper with that in other researches. The results show that: (1) Climate status has a significant impact on carbon policy, and carbon price predictions will dynamically change with climate status. (2) Green low-carbon behavior has a positive impact on climate status. (3) There are differences in the impact of the three types of damage caused by rising temperatures on carbon price policies. (4) Green development is conducive to stabilizing the value of SCC. (5) Close monitoring of the climate state helps to update the probability of damage in time so that we can precisely adjust the corresponding policies on SCC. This study provides theoretical and empirical reference for the government to formulate carbon price policies and promote the development of social green behavior. [ABSTRACT FROM AUTHOR]

This paper reviews the literature on foreign direct investment (FDI), productivity, and technology upgrading, with a focus on macroeconomic and microeconomic models. It compares the performance of various models used to study FDI and its effects on firms' productivity, via skill and technology upgrading, offshoring, institutional quality, and other related factors. This review highlights the differences and similarities between macroeconomic and microeconomic models, their empirical strategies, and their ability to provide a comprehensive understanding of the mechanisms through which FDI affects productivity and other variables. The empirical literature on the impact of FDI on the productivity of local firms is derived from association studies, which use a neoclassic production function and an augmented Solow-type equation. These models have been shown to be inadequate in capturing the dynamic and complex nature of FDI and the associated externalities, particularly vertical externalities. This paper identifies three criticisms of the literature on pecuniary externalities, including a lack of models that focus specifically on the mechanism of forward linkages, inadequate measures to assess linkage effects, and the failure to include crucial determinant factors in empirical models. Overall, this paper calls for more comprehensive and nuanced models that incorporate the dynamic and complex nature of FDI and its externalities. [ABSTRACT FROM AUTHOR]

In this paper, we establish a model based on real options theory and fractional Brownian motion (FBM) with jumps to price green bonds, and thus alleviate the externalities of green bonds. We assume that the floating value of green bonds is linked to the carbon price. The carbon emission trading mechanism and government subsidy policy are introduced into this model, and the expression is derived from the stochastic differential utility framework based on the fast Fourier transform method. Based on the numerical analysis and the simulations, this paper analyzes when governments are facing financial and carbon emission constraints and how policymakers balance the allocation between carbon allowances and government subsidies to help green bonds reach the exogenous equilibrium price. Our results have implications in terms of optimizing the distribution of economic resources by the reasonable pricing of green bonds. It is in line with the current theme of global energy conservation and emission reduction, and also has certain guiding significance for the development of the carbon emission trading market.

Heart failure impacts patients' quality of life and life expectancy and significantly affects the daily behaviours and feelings of family caregivers. At the end-of-life, the burden for family caregivers depends on their emotional and sentimental involvement, as well as social costs. Objectives: The aim of this work is to determine whether and how family caregivers' experiences and expectations vary in relation to the places of care and teams involved in heart failure management. Methods: A systematic literature review was conducted, by screening manuscripts dealing with the experience of Family Care Givers' (FCGs) of patients with Advanced Heart failure. Methods and results were reported following the PRISMA rules. Papers were searched through three databases (PubMed, Scopus and Web of Science). Seven topics were used to synthetize results by reporting qualitative information and quantitative evidence about the experience of FCGs in places of care and with care teams. Results: Thirty-one papers, dealing with the experience of 814 FCGs, were selected for this systematic review. Most manuscripts came from the USA (N = 14) and European countries (N = 13) and were based on qualitative methods. The most common care setting and provider profile combination at the end of life was home care (N = 22) and multiprofessional teams (N = 27). Family caregivers experienced "psychological issues" (48.4%), impact of patients' condition on their life (38,7%) and "worries for the future" (22.6%). Usually, when family caregivers were unprepared for the future, the care setting was the home, and there was a lack of palliative physicians on the team. Discussion: At the end-of-life, the major needs of chronic patients and their relatives are not health related. And, as we observed, non-health needs can be satisfied by improving some key components of the care management process that could be related to care team and setting of care. Our findings can support the design of new policies and strategies. [ABSTRACT FROM AUTHOR]

Knowledge accumulation is considered a crucial factor for generating sustained economic growth. Therefore, both knowledge spillovers and externalities are considered drivers of economic development. Standardization is a vital feature of technological progress. It involves triggering adoptions of innovation by reducing market uncertainty between consumers and producers. Standards cannot be implemented without using technology covered by the claims of patents. This paper investigates knowledge spillover through the inward and outward knowledge flow from technology standards. Studies have investigated the quantitative and qualitative effects of technological standards. However, there still exists a lack of understanding regarding the knowledge spillover and externality that results from technological standardization. The aim of this paper is to fill this gap in the literature by elucidating the codified knowledge spillover that underlies patented technologies at the technical, organizational, and industrial standard levels. This paper explores the characteristic patterns of knowledge spillover associated with technology standards. [ABSTRACT FROM AUTHOR]

The outbreak of COVID-19 causes a serious threat to human health and life around the world and puts enormous pressure on the healthcare system. The lockdown policy has effectively reduced the number of cases and suppressed the spread of the COVID-19 epidemic, but it also requires high social and economic costs. In this paper, we aim to use feedback control to help decision-makers establish lockdown policies, which can effectively constrain the spread of the COVID-19 pandemic with minimalfinancial loss. The time-dependent susceptible-infected-removed (SIR) model is used for the dynamics of the COVID-19 pandemic. The feedback control is based on a modified nonlinear active disturbance rejection controller (ADRC) that includes modified nonlinear extended state and nonlinear state error feedback with parameters tuned by particle swarm optimization, and the performances are compared with a well-known proportional- –integral–-derivative (PID) controller. The final simulation results show that the modified nonlinear ADRC has better performances and is more robust against uncertainties in the parameters of the epidemiological model.

Enterprise Zone is an important part of the regional economic development strategy. This paper investigates the impact of overall urban development and construction of the National Big Data (Guizhou) Experimental Area on the housing prices and found out that the construction of the National Big Data (Guizhou) Experimental Area is more conducive to the rise in suburban housing transaction prices. The paper empirically proves that the construction of the National Experimental Zone is more conducive to small family housing and leads to the increase in the suburban housing trading area, which further implies that the National Big Data (Guizhou) Experimental Area project may lead to the migration of residents to the suburbs, thus the increasing the housing price. Such regional planning is conducive to the changing spatial distribution of the residents, relocating the residents to find jobs and live in the suburbs, and increasing the value of suburban areas. This paper provides evidence to quantify the externalities and the premium of the housing prices in the surrounding area and provides empirical evidence on the spatial externalities in the literature.

In this paper, we aim to investigate the collusive stability in the presence of network externalities among firms with relative performance in the firm's objective functions. We demonstrate that collusive stability is increasing (decreasing) in the degree of relative performance, product substitutability and network effect when the network effect is sufficiently large (small). A competition agency might need to provide different guidance for anti-competitive regulation in the network industry. [ABSTRACT FROM AUTHOR]
