New trade theory converges to the old trade theory—An elementary theoretical perspective

AbstractWe introduce factor specificity to reflect the cost of adjustment of reallocating factors between technologies that determine fixed costs and variable costs in a typical Dixit–Stiglitz–Krugman (DSK) model of trade, retaining all other standard specifications of such a framework. We show that such an apparently benign change fundamentally alters the results of the DSK model. The number of varieties and output per variety depends entirely on full employment conditions. Thus, DSK and Heckscher–Ohlin–Samuelson (HOS) models, which represent the major workhorses of old trade theory, converge in the sense that now the number of varieties and outputs per variety are completely determined by factor endowments.

Patient Harm Events and Associated Cost Outcomes Reported to a Patient Safety Organization.

The aims of the study were to describe inpatient harm events detected via an automatic electronic trigger system (ETS) and to consider their financial consequences. Over a 27-month period, inpatient harm events were identified and documented in 1 healthcare system with 37 acute care facilities. Patients who experienced harm (all harm or preventable harm only) were compared with similar patients who did not. Clinical, financial, and demographic data were used to identify labor-adjusted direct variable costs (DVC) and potential differences in length of stay (LOS) associated with all-harm, preventable-harm, and nonharmed cohorts. Age-adjusted Charlson Comorbidity Index, case mix index, diagnosis-related groups, major diagnostic category, sex, age, location, diagnosis, adverse event category and subcategory, preventability, and harm severity were used to compare cohorts. Total harm events reported via the ETS and the health system's voluntary event reporting system were compared. Nearly 93,000 encounters for all-harm (n = 25,665) and nonharmed cohorts (n = 67,217) were compared by random sampling of diagnosis-related group-matched all-harm and nonharmed groups to ensure similar clinical conditions, as measured by Charlson Comorbidity Index and case mix index. Sampling (2 groups, n = 100 and n = 200) showed that increased LOS was associated with harm; yet other clinical comparators were similar across groups. the preventable-harm subcohort had longer LOS (10.7 versus 5.9 days) and higher DVC ($13,442 versus $8024) than the nonharmed cohort. Identification of harm events was nearly 6-fold higher with the ETS than with the voluntary event reporting system. Patients with preventable harm had increased LOS that was associated with higher DVC per preventable-harm encounter in a large US healthcare system.

SOCIOECONOMIC DYNAMICS AND PROFITABILITY DRIVERS IN BROILER CHICKEN PRODUCTION IN SABON GARI LOCAL GOVERNMENT AREA OF KADUNA STATE, NIGERIA

This study investigated the socioeconomic dynamics and profitability drivers in broiler chicken production in Sabon Gari Local Government Area (LGA) of Kaduna State, Nigeria. Multi-stage sampling procedure was used in selecting one hundred and fifty (150) broiler chicken producers. Primary data were collected through the use of a structured questionnaire. Tools of analysis used were descriptive statistics, farm budgetary techniques, and the multiple regression model. The socio-economic characteristics of the producers revealed a mean age of 44 years, with the majority (62.50%) of the producers being male. The broiler farmers had one form of education or another, with a mean flock size of 213 birds. It was found that the percentage contribution of the purchase of feed to the total variable cost of production was the highest (45.79%), with a sum of ₦ 756.06 at average as the total cost incurred in the production of broilers was realized. Consequently, the return on Naira invested of ₦ 1.38 implies that for any ₦ 1 invested in broiler production, the farmers generated 38k. The results from regression analysis revealed that sex, age, farming experience, household size, education, and membership in cooperatives were the determinants of the profitability of broiler chicken production. It was concluded that broiler production in the study area was profitable and that several socio-economic factors significantly influence profitability. It was therefore recommended that producers consider joining cooperative membership to explore the benefits of cooperatives and leverage bulk purchasing discounts and knowledge sharing opportunities, potentially improving profitability for members.

Utilizing Agricultural By-Products for Sustainable Agouti (Dasyprocta leporina) Diets: Evaluating Low-Cost Feed Alternatives in Trinidad and Tobago, West Indies

The agouti (Dasyprocta leporina) is a promising protein source in the Caribbean, Mexico, and South America. This study assessed the impact of three by-product diet formulations on intensively reared agoutis, including a cost analysis and nutritional evaluation as well as the nutritional composition, digestibility, and economic viability of three experimental diets. Sixteen adult male agoutis were individually housed at the University of the West Indies’ Field Station. After a two-week acclimatization, a four-week data collection phase followed. The four treatments included a control diet of commercial rabbit pellets and three experimental diets with varying by-product ratios. Key findings revealed that Treatment 2 had elevated Dry Matter, Crude Fat, and fiber but potentially compromised digestibility due to higher fiber and lignin. Treatment 1 resulted in the highest morbidity and was discontinued after two weeks due to significant weight loss but demonstrated the most cost-effective results, with the lowest variable cost per 45 kg, the lowest feeding cost to reach 3 kg, and the highest gross margin. Treatment 2 effectively maintained animal weight. Treatment 3 showed promising growth due to low levels of Neutral Detergent Fiber (NDF) and Acid Detergent Lignin (ADL). Alternative dietary feedstuffs from agricultural by-products show potential for sustaining body weight in adult male agoutis, but further research is needed to refine nutritional requirements for growing agoutis.

Scenarios on future electricity storage requirements in the Austrian electricity system with high shares of variable renewables

This paper presents three scenarios (policy, renewables and electrification and efficiency) for transitioning to a 100 % renewable electricity sector in Austria, based predominantly on wind and photovoltaics, alongside sector-specific electrification. Considering renewable expansion targets and three distinctive weather years from an overall system perspective, the core objective is to minimize variable costs of electricity storage and dispatchable power plants. The model developed determines their optimal dispatch for meeting the underlying electricity demand each hour. Within the scenarios for renewable expansion, a special focus lies on integrating short-duration (batteries), medium-duration (pumped storage hydro) and long-duration (hydrogen) energy storage. Our analysis reveals the significant impact of weather patterns on renewable electricity generation, particularly the differences between winter and summer generation quantities. This necessitates seasonal balancing and the mitigation of extremes like low wind power events, which require corresponding backup capacities. This contrast is particularly evident when comparing the years 2030–2050, wherein in the latter, certain dispatchable generators are only utilized in one of the three underlying weather years during extreme weather conditions. In our paper, we demonstrate how, especially for hydrogen production and storage, weather conditions influence production levels and the re-electrification demand. The results indicate the feasibility of achieving a fully decarbonized energy system in Austria through suitable policy measures and expanded renewable generation, with long-duration storage playing a crucial role in seasonal balance and compensating for the absence of fossil fuel generation. Strategic planning is essential to aligning the expansion of renewable energy generation with the necessary flexibility.

Exploitation of Mineral Resources in Conditions of Volatile Energy Prices: Technical and Economic Analysis of Low-Quality Deposits

In mining projects and production operations, energy carrier costs (fuel, electricity) constitute the primary component of variable costs. This study outlines a methodology for projecting operating costs in a surface mine or quarry in order to find the optimal configuration of mining equipment to extract low-grade secondary deposits, taking into account volatile energy prices. For illustration, the operating costs of five variants of mining equipment deployed to mine low-grade products were analysed, with the price of energy and fuels being the key cost component and the main risk factor. There were differences between the initial investment outlays and operating costs involved in all analysed variants, whilst the starting point for estimating the technical and economic parameters involved in the respective solutions was the predefined configuration of the mining equipment. Further, the decision to commence or discontinue mining operations could be supported by the simulation procedure based on the economic model. The results provided valuable insights into the cost-effectiveness of low-grade deposit extraction scenarios, depending on the projected unit costs of fuels and energy.

Entry cost, fixed cost and markup: Theory and evidence from the impact of corruption on prices

The welfare costs of markups are large. We analyze the impact of firm’s entry cost, fixed cost, and variable cost on markups using a general equilibrium model. The results show that entry cost induces higher markups, whereas fixed cost reduces markups with a stronger effect in low-income countries and for high-quality goods. As an empirical application, we examine the impact of corruption on the prices of identical products across countries. We find that the prices and markups are higher in more corrupt countries, and the effect is stronger in low-income countries and for high-quality products. These results suggest that corruption causes higher entry costs and fixed costs, leading to a fewer number of firms and more misallocations among firms in equilibrium. Therefore, the model is useful for distinguishing entry and fixed costs empirically, and it highlights the importance of identifying the nature of the cost to better understand their impact on markups and welfare.

Impact of a family support intervention on hospitalization costs and hospital readmissions among ICU patients at high risk of death or severe functional impairment

BackgroundPatients with advanced critical illness often receive more intensive treatment than they would choose for themselves, which contributes to high health care costs near the end of life. The purpose of this study was to determine whether a family support intervention delivered by the interprofessional ICU team decreases hospitalization costs and hospital readmissions among critically ill patients at high risk of death or severe functional impairment.ResultsWe examined index hospitalization costs as well as post-discharge utilization of acute care hospitals, rehabilitation and skilled nursing facilities, and hospice services for the PARTNER trial, a multicenter, stepped-wedge, cluster randomized trial of an interprofessional ICU family support intervention. We determined patients’ total controllable and direct variable costs using a computerized accounting system. We determined post-discharge resource utilization (as defined above) by structured telephone interview at 6-month follow-up. We used multiple variable regression modelling to compare outcomes between groups. Compared to usual care, the PARTNER intervention resulted in significantly lower total controllable costs (geometric mean: $26,529 vs $32,105; log-linear coefficient: − 0.30; 95% CI − 0.49, − 0.11) and direct variable costs ($3912 vs $6034; − 0.33; 95% CI − 0.56, − 0.10). A larger cost reduction occurred for decedents ($20,304 vs. $26,610; − 0.66; 95% CI − 1.01, − 0.31) compared to survivors ($31,353 vs. $35,015; − 0.15; 95% CI − 0.35,0.05). A lower proportion in the intervention arm were re-admitted to an acute care hospital (34.9% vs 45.1%; 0.66; 95% CI 0.56, 0.77) or skilled nursing facility (25.3% vs 31.6%; 0.63; 95% CI 0.47, 0.84).ConclusionsA family support intervention delivered by the interprofessional ICU team significantly decreased index hospitalization costs and readmission rates over 6-month follow-up.Trial registration Trial registration number: NCT01844492

Monopsony Power and Cost Structure: Evidence from the U.S. Hospital Industry

ABSTRACT We examine the association between monopsony power and hospital cost structure using data from more than 2,000 U.S. hospitals. Monopsony characterizes a market with a single buyer and many suppliers. Accordingly, monopsony power is a potentially critical determinant of cost structure because it affects managers’ resource procurement decisions. Results indicate that hospitals with monopsony power adopt more elastic cost structures, and monopsony power magnifies the positive relationship between demand uncertainty and cost elasticity identified in prior research. These findings suggest monopsony power lowers the costs of procuring resources on flexible, short-term, and variable bases as opposed to making long-term commitments. Therefore, due to the high fixed-cost nature of the industry, hospitals with monopsony power choose more variable cost structures and make larger cost structure adjustments in response to demand uncertainty. Although we conduct this research using hospitals, our theory and results have implications for other industries. Data Availability: Data are publicly available from the sources cited in this study. JEL Classifications: D22; D23; I11; M20; M40.

A Case Study on Economic Analysis of Sea Cage Farms in the Black Sea, Türkiye

The main aim of this research is to understand the value chains of enterprises engaged in aquaculture in sea cages in the Black Sea region of Türkiye, to determine production costs and to make a general analysis of the aquaculture sector. Random sampling method was used to ensure that farmers were equally represented in the survey. Data for the survey were randomly selected from 16 separate farms spread throughout 4 different marine cage locations. Furthermore, fish traders and sector stakeholders were interviewed. The businesses examined within the scope of the study are divided into 3 groups: small (250 -500 tons/year), medium (501-999 tons/year) and large (>1000 tons/year), according to their capacities. The most important expense items of enterprises consist of variable costs. Among the variable costs, the purchase of fry fish, feed purchase, and labor costs constitute the most important expenditure items. Among the fixed costs, the most important expense is depreciation costs. The unit cost of one kg of fish varies between 2.7 and 3.0 euros. Considering that the trout (Oncorhynchus mykiss) and seabass (Dicentrarchus labrax) in the Black Sea are at the level of 3.5 Euro, the profit rate of the enterprises is between these levels. Recently, since trout from the Black Sea has been exported to the Far East Country (particularly Japan), its price has also increased. In 2018, the average retail price (including VAT) and medium selling price of seabass and trout were at a level of 5.24 and 5.34 Euros respectively. Despite all these positive developments, climate change continues to pose a threat in terms of disease outbreak and marketing problems.

Diagnosing Incipient Faults for a Faster Adoption of Sustainable Aerospace Technologies

Next-generation aircraft require the development and integration of a deal of innovative green technologies to meet the ambitious sustainability goals set for aviation. Those transformational efforts are associated with a tremendous increase in the complexity of the onboard systems and their multiphysics-coupled behaviors and dynamics. A critical aspect relates to the identification of the coupled faults resulting from the integration of those green technologies, which introduce damage identifiability issues and demand new approaches for the efficient and accurate identification of non-nominal fault conditions. Model-based fault detection and identification (FDI) methodologies have been proven essential to identify onboard the damages affecting the systems from physical signal acquisitions, but existing methods are typically computationally expensive and fail to capture incipient coupled faults, which prevents their adoption and scaling with the increasing complexity of novel multiphysics systems. This work introduces a multifidelity framework to accelerate the identification of fault modes affecting complex systems. An original two-stage compression computes an optimally informative and highly reduced representation of the monitoring signals for the minimum demand of onboard resources. A multifidelity scheme for Bayesian inversion is developed to infer multidomain fault parameters from the compressed signals: variable cost and fidelity models are optimally queried for a major reduction of the overall computational expense. The framework is demonstrated and validated for aerospace electromechanical actuators affected by incipient multimodal faults. Remarkable accelerations of the FDI procedure are observed, and the exact identification of the incipient fault condition was achieved one order of magnitude faster than with standard algorithms.

Comparison of different optimization techniques applied to optimal operation of energy storage systems in standalone and grid-connected direct current microgrids

This study addresses the problem of optimal operation and functioning of lithium-ion batteries in direct current (DC) microgrids with photovoltaic generators, in both urban and rural settings, under an approach that considers three mathematical models as objective functions: reduction of operational costs, reduction of power losses associated with energy transport, and reduction of CO2 emissions produced by conventional generators. After defining the objective functions, six optimization algorithms are integrated as solution methodologies: Equilibrium Optimizer (EO), Salp Swarm Algorithm (SSA), Particle Swarm Optimization (PSO), Sine and Cosine Algorithm (SCA), Black Hole Optimizer (BHO), and the Generalized Normal Distribution Optimizer (GNDO) algorithm. These methodologies are used to determine the hourly power flow through successive approximations, thus evaluating each of the objective functions with the system’s constraints in order to achieve reductions of each objective function and thereby confirm the quality of the solutions applied to the problem under analysis. Where, for the urban case of Medellín, the optimization achieved minimum reductions of 0.163% in fixed costs, 1.436% in variable costs, 7.160% in power losses, and 0.165% in CO2 emissions. In the rural case of Capurganá, the results showed minimum reductions of 0.095% in energy costs and 10.938% in power losses. These numerical results confirm the effectiveness of the applied optimization algorithms in reducing operational costs, power losses, and emissions, thereby validating the quality of the solutions for the analyzed problem.

Contractual Mechanisms in National Park Management: A Multi-Task Principal–Agent Model

In the management of national parks, the principal–agent relationship is key to efficient and effective management. Based on multi-task principal–agent theory, this study examines the dual functions of central government incentives and guidance and the objectives of local National Park Administration offices in environmental conservation and reasonable resource utilization. First, this study constructs a multi-task principal–agent model for central and local governments within the national park management system and identifies effective contractual mechanisms. Second, this study examines the relationship between the intensity of central government incentives and the ecological conservation atmosphere coefficient. Third, by integrating the three stages of national park management system advancement, this study explores the central government’s incentive strategies at different stages. The findings indicate that local governments receive limited ecological conservation support, underscoring the need for long-term central government incentives. The findings also confirm that the effective management of national parks by local governments can only be achieved by eliminating external uncertainties, reducing the variable costs of innovative advancements, and controlling risk aversion in local National Park Administration processes. In addition, this study includes empirical data for sensitivity analyses to understand the robustness of the model under different scenarios. This study offers valuable insights and practical suggestions for enhancing national park management.

تقدير الكفاءة الاقتصادية والفنية لمشاريع تسمين العجول في محافظة واسط للعام 2022

Calf breeding and fattening projects in general are considered the main source of meat production in Iraq. This vital and widespread sector is considered the largest in Wasit Governorate. There are a significant number of fields specialized in raising and fattening calves. Despite the increase in production that the owners of these fields have experienced, these Owners face difficulties in obtaining expensive feed and poor vaccines, veterinary services and treatments imported and controlled by the private sector, which has led to high economic costs. Calf fattening projects have similar social and economic advantages. Calf fattening, which is a sub-sector of the livestock sector, has an important role in transforming... Calves turn into high-quality and efficient beef through economic use. Increased live weight, feed intake, feed efficiency and capacity, and the relationship between profitability are direct factors on calf breeding and fattening projects. The results showed that the total costs (fixed and variable) for the average projects in the sample amounted to approximately (136,779) one hundred and thirty-six million, seven hundred and seventy-nine thousand Iraqi dinars. Through the results, it was shown that the variable costs have a greater relative importance in the calf rearing and fattening projects in the study area than the fixed costs, and the other costs are due to the prices of the calves upon purchase (before the start of the fattening cycle), so their percentage reached (61.46%) of the total total costs, while the cost amounted to (61.46%). Net sale of one calf after fattening (2009000) is two million and nine thousand dinars The economic efficiency and its components for the calf rearing and fattening projects in the study sample were estimated using the DEAP data envelopment analysis method and according to the cost function variables in light of the resources used and their prices assuming changing returns to scale. The economic efficiency and its components, both the technical and Allocative efficiency of the calf breeders in the study sample, were estimated using the data envelopment analysis method (DEAP), and the results of the estimates of economic (EE), technical (TE), and Allocative (AE) efficiency were confirmed. By reviewing these results, it was found that the level of technical efficiency of the study sample ranged Between a minimum of about 72.4%) and a maximum of 100%), with an average of (97.5%). As for the number of fields that achieved full efficiency (100%), it reached 30 fields, and a percentage of (60%) was formed. As for the fields that achieved efficiency between (%80-100%) reached (49) fields, and as for the fields that achieved technical efficiency (72.4%), it was one field.
