The ecological value of cultivated land carries clear intergenerational implications, requiring a fair allocation mechanism across the full life cycle to address market failures caused by intergenerational externalities. This study constructs an intergenerational allocation model of cultivated land ecological value based on the Diamond framework. The intra-generational consumption elasticity coefficient is derived using the Tapio decoupling theory, with the ratio of cultivated land quantity change to per capita net income change as the core indicator. Statistical data from Lezhi County (1984–2022) are used for empirical analysis. The fitted elasticity coefficient shows a steady decline and eventually converges to zero, indicating a weakening willingness of the current generation to consume ecological value, thus supporting the logic of preserving value for future generations. A simplified Pearl growth curve is then used to construct the development stage coefficient, representing the evolving realization of ecological value among future generations. Engel coefficient forecasts based on the GM(1,1) model enable year-by-year estimation of ecological value allocation to future generations. The results show that (1) the ecological value of cultivated land in Lezhi County is estimated at CNY 65,498,230/ha, (2) the proposed model effectively simulates intergenerational value allocation, (3) decoupling theory supports the hypothesis of equal intergenerational sharing, and (4) the development stage coefficient curve provides a dynamic perspective on long-term ecological value realization. This research offers a data-driven modeling approach that enhances both the fairness and the efficiency of land governance, contributing methodological support for sustainable cultivated land protection and ecological compensation policies.

The simplified tax system is the most common special tax regime in the Russian Federation in terms of the number of taxpayers. Tax revenues from the simplified tax system account for 6% of the structure of tax revenues of the consolidated budgets of the constituent entities of the Russian Federation and more than 93% of the structure of tax revenues from special tax regimes. The purpose of this study is to identify and assess the factors influencing tax revenues from the tax levied in connection with applying the simplified system of taxation (taxable object—income reduced by the amount of expenses). The objective of this study is to determine a set of factors used by economists to model the level of tax revenues and to conduct a corresponding econometric analysis of the influence of the selected factors on the dependent variable to identify characteristics of the simplified taxation system functioning in the Russian Federation. The object of this study is the per capita tax revenue from the tax levied in connection with applying the simplified system of taxation (the object of taxation is income reduced by expenses) in the Russian Federation. The subject of the research is a set of economic relations, which arise because of tax-legal relations between tax authorities and taxpayers in relation to the calculation of the tax levied in connection with the application of the simplified taxation system. This study’s hypothesis is that the amount of tax revenues is influenced by factors characterizing the economic situation and development of small and medium businesses in the constituent territories of the Russian Federation. This study was conducted in 83 constituent territories of the Russian Federation in 2020–2022. The research methods are statistical analysis and econometric modeling on panel data. During this study, six econometric models were constructed. Based on the results of specification tests, the least squares dummy variables model was selected. The results of the modeling show that the tax rate, the number of taxpayers, and the real average per capita monetary income of the population have a statistically significant impact on the per capita tax revenue under the simplified tax system (the object of taxation is income reduced by the number of expenses). As a result, the focus of economic policy at both macro and meso levels should be on the support of small and medium-sized enterprises in the early stages of their life cycle, as well as on the increase of the purchasing power of the population. Based on the results obtained, it is possible to forecast the revenue side of the budgets of the constituent entities of the Russian Federation. Full article

The environmental and occupational risk we confront from agricultural chemicals increases as their presence in natural habitats rises to hazardous levels, building a major part of the exposome. This is of particular concern in low- and middle-income countries, such as Brazil, known as a leading producer of agricultural commodities and consumer of pesticides. As long as public policies continue to encourage the indiscriminate use of pesticides and governments continue to support this strategy instead of endorsing sustainable agricultural alternatives, the environmental burden that damages epithelial barriers will continue to grow. Chronic exposure to environmental contaminants in early life can affect crucial barrier tissue, such as skin epithelium, airways, and intestine, causing increased permeability, leaking, dysbiosis, and inflammation, with serious implications for metabolism and homeostasis. This vicious cycle of exposure to environmental factors and the consequent damage to the epithelial barrier has been associated with an increase in immune-mediated chronic inflammatory diseases. Understanding how the harmful effects of pesticides on the epithelial barrier impact cellular interactions mediated by endogenous sensors that coordinate a successful immune system represents a crucial challenge. In line with the epithelial barrier hypothesis, this narrative review reports the available evidence on the effects of pesticides on epithelial barrier integrity, dysbiosis, AhR signaling, and the consequent development of immune-mediated inflammatory diseases.

This paper establishes an empirical relationship between CO₂ emissions from burning fossil fuels and household consumption of nondurable goods and services. Using a typical life cycle-permanent income hypothesis framework, we reject the hypothesis that inclusion of CO₂ emissions in the consumption function is not supported by the data. Furthermore, our results suggest the existence of a distaste effect or negative state dependence effect. This result has important policy implications as it suggests that decarbonizing the economy would ultimately stimulate household consumption. Our results also have implications for both the cyclical behavior and the smoothing process of consumption, which depend on the branch of the environmental Kuznets curve that the country is on as well as on the prevalence of intertemporal dependent preferences.

The invasion success of non-native fish, such as Pyrenean gudgeon Gobio lozanoi in several Iberian rivers, is often explained by the expression of its life history traits. This study provides the first insights into the reproductive traits, fish condition, and energy allocation (protein and lipid contents of tissues) of this species, along a longitudinal gradient in one of the most regulated river basins in the Iberian Peninsula, the Segura river. Larger sizes of first maturity, higher fecundity and larger oocytes were found in fluvial sectors with the most natural flow regimes, characterised by a low base flow with high flow peaks in spring and autumn. A delay in the reproductive period, lower fish condition and no differences in sex-ratio were observed in fluvial sectors with a high increase in base flow and notable inversion in the seasonal pattern of flow regime. Lipid contents in the liver and gonads were stable during the reproductive cycle and decreases in muscle were noted, whereas ovarian and liver proteins increased. In relation to energy allocation for G. lozanoi, an intermediate energy strategy was observed between income and capital breeding. Our results support the hypothesis that the high plasticity of G. lozanoi population traits plays a significant role in its success in a highly regulated Mediterranean river basin. Understanding the mechanisms by which flow regulation shapes fish populations in Mediterranean type-rivers could inform management actions. Full article

Background: The stimulus coupon plan is one of the economic relief plans used to boost Taiwan’s slumping economy in the aftermath of the COVID-19 pandemic outbreak. In order to obtain prior information to understand whether or not the stimulus coupon plan would effectively revive the economy in advance, the purpose of this study is to learn lessons from Taiwan’s consumption voucher scheme initiated during the 2007–2009 global financial crisis through evaluating the effect of the consumption voucher scheme on private consumption expenditure. Methods: The smooth time-varying cointegration analysis was applied to estimate the income elasticity of consumption, indicating the individual’s reaction to consumption vouchers in terms of private consumption expenditure, and then the multiple structural change model was estimated to identify endogenous regime changes of the income elasticity of consumption. Results: We found that the income elasticity of consumption dramatically decreased after 2007Q1, a period that covered the subprime mortgage crisis in 2007–2009 and the time of issuance of the consumption vouchers in 2009. Conclusions: We concluded that Taiwan’s consumption voucher scheme might have had either no or little effect on stimulating the economy, so policymakers should be cautioned concerning the potential ineffectiveness of the stimulus coupon plan in the future.

It is of vital importance to examine the relationship between pensions and household consumption/saving because this forms a link between social policy and economic development. Based on theories of absolute income, permanent income, and the life-cycle hypothesis, this paper constructs panel data models to investigate the effect of public pension participation and benefit level on household consumption. Evidence from the China Health and Retirement Longitudinal Study (CHARLS) 2011 and 2013 survey data shows that, compared with those not covered by any public pension program, individuals enrolled in the public pension system tend to consume more within respective income-quantile groups. Moreover, for the retired population, we found lower income groups have a higher marginal propensity to consume than higher income groups. In other words, lower income groups are likely to spend a higher proportion of any increase in pension benefit on consumption than higher income groups. To achieve a virtuous cycle between public pension, household consumption, and economic growth and, thus, a social-economically sustainable development, we suggest that China’s pension system should be extended to cover all in the lowest income group, and the benefit level should be increased gradually to secure a stable expectation for the future and motivate current consumption.

This article aims to investigate the environmental and economic sustainability of five dairy farms in the Umbria Region (Italy). The study also provides an assessment of aggregate sustainability, which is less investigated with reference to cattle milk both globally and in Italy, through the analysis of the relationship between economic and environmental performance. Primary data were collected through a direct survey carried out in 2014. The environmental assessment was conducted with a Life Cycle Assessment (LCA) “cradle to farm gate” approach, while the economic dimension was evaluated by determining the direct and indirect costs related to the factors involved in the production process. A correlation analysis and a linear regression were performed in order to study the relationship between the carbon footprint (CF) and operating income. The average operating income amounted to 0.03 Euro/L of milk. The CF values of the five companies are contained within a variation range comprised between 0.90 and 1.76 kg CO₂ eq/L of milk. The existence of an inverse relationship between the CF of milk and operating income confirms the hypothesis regarding the possibility of implementing strategies aimed at improving performance in both investigated dimensions at the same time, thus increasing the aggregate sustainability.
