Impact of media attention on corporate green innovation: What is the role of dual environmental regulation?

This study explores the intricate interplay between media attention, dual environmental regulation, and corporate green innovation quality using a comprehensive dataset of Chinese A-share listed companies. Thus, our rigorous empirical analysis reveals that media visibility significantly affects corporate environmental sustainability efforts, with formal and informal environmental regulations moderating its impact. Media attention acts as a powerful catalyst for green innovation during growth and mature stages of a company's lifecycle; however, its effect diminishes during recessions. We determine significant heterogeneity across industry types and ownership structures. Non-high-polluting industries and non-state-owned enterprises show stronger positive responses to media scrutiny in their green innovation efforts than high-polluting sectors and state-owned enterprises. Furthermore, formal environmental regulations amplify the positive effect of media attention on green innovation, suggesting a synergistic potential that encourages companies to exceed baseline environmental standards. In contrast, while having no direct impact on green innovation, informal environmental regulation significantly moderates the relationship between media attention and innovation quality. These findings add to the literature on environmental innovation by demonstrating the conditional effectiveness of media attention and the critical role of regulatory frameworks in fostering sustainable corporate practices across industries and ownership contexts, with implications for policymakers, corporate strategists, and environmental advocates.

Managing Growth of Product Lifecycle at Maturity Level: A Systematic Literature Review

Through the synthesis and analysis of 64 papers, from JSTOR, ScienceDirect, and Google Scholar data bases, include 2010-2024 of 15 years duration paper works. this systematic literature review identified major themes and provided insights into growth management strategies, marketing tactics, challenges, and opportunities, benefits, that managers confront in their quest to sustain competitiveness and profitability in mature markets. Product diversification, market segmentation, innovation management, cost-effective lifecycle planning, price strategies, market expansion, client retention, alliances, and collaboration are a few examples of important tactics. The difficulties include growing rivalry, market saturation, shrinking profit margins, and shifting consumer tastes. To maintain competition, there are nevertheless still chances to take advantage of economies of scale, brand equity, and customer loyalty. The review's insights deepen our understanding of how businesses may best manage opportunities and overcome obstacles to maximize product lifecycle management at various stages of maturity. By providing a comprehensive understanding of the existing body of knowledge, this review offers valuable insights for practitioners, managers, and researchers aiming to enhance product lifecycle management (PLM) strategies at the maturity level, ultimately contributing to the development of more resilient and adaptive business models and research gaps have identified that enabled to provide future research directions.

Carbon Sequestration Through Forestry: A Differential Equation Approach

Carbon sequestration through forestry represents a promising approach to partially counteract anthropogenic greenhouse gas emissions driving climate change. Tree growth naturally removes carbon dioxide from the atmosphere, storing it as biomass. Sustainably managed forests can effectively function as carbon sinks. However, determining optimal forestry policies involves balancing complex ecological dynamics with economic constraints. This study develops differential equation models quantitatively capturing forest growth, timber harvesting, and carbon sequestration dynamics. Logistic models are first adapted to simulate biomass accumulation of representative tree species. Lifecycle growth patterns spanning juvenile to mature phases are incorporated, along with climate effects. Biomass levels are proportionally related to carbon dioxide removal rates from the atmosphere. Deforestation impacts are analyzed by incorporating harvesting-induced biomass reductions. Sustainability constraints are implemented to ensure minimum viable tree densities across harvest rotations. Optimization techniques then identify management guidelines maximizing economic returns given ecological stability considerations. The goal is providing quantitative insights into rotation lengths, planting densities, and allowable cuts upholding both climate change mitigation and commercial demands. Findings can inform science-based forestry policies to leverage forests as sustainable natural carbon sinks.

The looming fiscal reckoning: Tax distortions, top earners, and revenues

How should the U.S. confront the growing revenue needs driven by higher spending requirements? We investigate the mix of potential tax increases that generate a given revenue need at the minimum welfare cost and evaluate its macroeconomic impact. We do so in the context of a life-cycle growth model that captures key aspects of the earnings and wealth distributions and the non-linear shape of taxes and transfers in place. Our findings show that a proportional consumption tax combined with a lump-sum transfer to all households and a reduction in income tax progressivity consistently emerges as the best alternative to minimize welfare costs associated with a given increase in revenue. A 30% long-run increase in Federal tax revenue requires a consumption tax rate of 27.8%, a transfer of about 12% of mean household income to all households, and a reduction of top marginal income tax rates of more than 5 percentage points—output declines by 7.9% in the long run. While transfers are substantial, smaller transfers can accomplish most of the reduction in welfare costs. We find no role for wealth taxes in increasing revenues or minimizing welfare costs.

The Size and Life-Cycle Growth of Plants: The Role of Productivity, Demand, and Wedges

Abstract What determines the distribution of establishments in terms of size and life-cycle growth? How are those determinants related to aggregate productivity? We provide novel answers by developing a framework that uses price and quantity information on establishments’ outputs and inputs to jointly estimate the demand and production parameters, and subsequently, establishments’ quality-adjusted productivity, deriving both micro-level and aggregate implications. We find that the dominant source of variation in establishment size is variation in quality/product appeal but that variation in technical efficiency plays an important supporting role. Multiple factors dampen dispersion in establishment size including dispersion in input (quality-adjusted) prices, markups, and residual wedges. Relatively moderate dampening factors induce large aggregate allocative efficiency losses relative to their absence. We show that joint estimation of the parameters of the demand and production function crucially affects inferences on the determinants of the size distribution of firms and their implications for aggregate productivity.

Job Creation in Colombia Versus the USA: ‘Up‐or‐out Dynamics’ Meet ‘The Life Cycle of Plants’

One of the most striking contrasts between the anatomies of the business sectors in higher‐ versus lower‐income economies is the overwhelming dominance of very small production units in the latter. Contrasting manufacturing sector data for Colombia and the USA, we show that weaker ‘up‐or‐out’ dynamics are behind this pattern and behind weaker average lifecycle growth. Dampened growth dynamics, not only in terms of upward mobility but also for exit and downward mobility, characterize both micro‐establishments and young establishments in Colombia relative to their US counterparts. These patterns lead to a more dominant role of small older businesses in accounting for employment. Since dynamic selection among startups is a crucial driver of productivity growth in the USA, our findings point to a shortage of high‐growth entrepreneurship and a relative high likelihood of long‐run survival for small, likely unproductive plants, as two key elements at the heart of the development problem. We also show that analysis of establishment lifecycle dynamics based solely on cross‐sectional data substantially underestimates lifecycle growth.

New product development in micro, small, and medium-sized enterprise-based agriculture products: a valuation technology approach

The innovation from university can assist Micro, Small, and Medium-sized Enterprises (MSMEs) in growing their business. However, because the technology has not been tested, MSMEs are still hesitant to adopt it. As a result, the objective of the research is value the innovation produced by the researcher at university that can add value to MSME products and business development. We employ a technology valuation application as a decision-making tool for valuing and predicting license prices for innovative technology to be commercialized. The use of mangosteen rind powder as a natural preservative on the physicochemical characteristics of coconut sugar had a risk factor of 0.4277, with a technology class of moderate risk, and was located in the technological life cycle's growth area and the product life cycle's diffusion area. The technology license price was IDR 302,042,177 and the diffusion of new technical consumer features was a growing field of innovation. As a result, to attract late adopters, it was necessary to project a positive image of technology beneficial to their health. The study's relevance is based on the patient-oriented technology valuation system, which can anticipate the price of new technology that has the potential to be commercialized.

Corporate investment and growth opportunities: The role of R&D-capital complementarity

How does the interaction of uncertainty and R&D impact corporate investment? We provide evidence that R&D significantly increases corporate investment responsiveness to PVGO news and uncertainty shocks. These results are consistent with predictions from the R&D-based real options model of corporate investment. To establish credible causal results we combine new measures of systematic and firm-specific PVGO shocks, for which we utilize stock price and option data, with exogenous measures of R&D capital stocks derived from panel variation in state R&D tax credits. We also rule out a number of potentially competing explanations for our results, including firm-level differences in lumpiness of investments, financial frictions, lifecycle growth opportunities or moral hazard-implied asset substitution or risk shifting.

Mobility of arsenic in the growth media of rice plants (Oryza sativa subsp. japonica. ‘Koshihikari’) with exposure to copper oxide nanoparticles in a life-cycle greenhouse study

The increasing arsenic (As) concentration in agriculture media poses increasing risks to both environment and human health. Arsenic mobility determines its bioavailability and entry into the food chain. Nanoparticle application may help to control As mobility in crop cultivation media, and thus decreasing As bioavailability for plants. This research studied the adsorption kinetics of As(V) on copper oxide nanoparticles (nCuO) and nCuO dissolution in a hydroponic solution, and the effects of nCuO on As mobility in a greenhouse system exposed to As(V) addition of 10 mg/kg and nCuO at 0.1–100 mg/L for a life-cycle growth of rice. Arsenic adsorption was dependent on both the total mass and the concentration of nCuO as well as the initial concentration of As(V), while nCuO dissolution was mainly dependent on nCuO concentration regardless of As(V). Arsenic in the simulated paddy was quickly mobilized from soil to aqueous phase during week 1, and further interacted with components in water phase, sediment-water interfacial transition and rice plants. Copper (Cu) and As speciation in the soil were observed by X-Ray Absorption Near Edge Spectrometry. Dissolved Cu was complexed with organic ligands. As(V) was adsorbed to kaolinite, or reduced to As(III) and adsorbed to ferrihydrite. Percent As removal from water phase in the growth container was determined by both nCuO application and As(V) initial concentration. Based on our previous finding that As accumulation in rice grains was significantly decreased by nCuO at 50 mg/L and the results of this study on As adsorption capacity of nCuO and As removal from water due to nCuO application, nCuO at 50 mg/L was proposed to be an appropriate application in rice paddy to immobilize As. Further research is needed in actual agriculture to verify the appropriate nCuO application and get an integrated beneficial effect for rice plants and humans.

The Size and Life-Cycle Growth of Plants: The Role of Productivity, Demand and Wedges

We develop a framework that uses price and quantity information on both establishments' outputs and inputs to assess the roles, on establishment dynamics and welfare, of technical efficiency, input prices, demand/quality, idiosyncratic markups, and residual wedges. Our strategy nests previous approaches limited by data availability. In our application, demand/quality is found to dominate the cross sectional variability of sales and sales growth, while quality-adjusted input prices and residual wedges play dampening roles, especially at birth. Markups play only a modest role for cross-sectional variability of sales and sales growth but are important in explaining welfare losses from revenue productivity dispersion.

Contracts, Firm Dynamics and Aggregate Productivity

We construct a framework of firm dynamics to evaluate the impact of the enforcement of contracts between final goods producers and their intermediate goods suppliers on firm life-cycle growth, technology accumulation and aggre-gate productivity. We build upon the tractable contracts model of Acemoglu et al. (2007), where the final goods firm chooses technology in contractible activi- ties conducted by suppliers of intermediate inputs. Suppliers select investments in noncontractible activities, anticipating the pay offs of a bargaining game with the producer of the final goods. We show that contractual incompleteness im-plies a wedge on profits for producers of final goods, potentially dependent on the level of technology of the firm, which disincentives technology accumulation at the firm level in our dynamic model. We evaluate this mechanism in general equilibrium to analyze its quantitative implications. Our model accounts for differences in output per worker of up to 33 percent across economies with complete and incomplete contracts. The impact on firm life-cycle growth, the age and size distribution of firms is quantitatively significant.

Clusters’ Impact on Firm Performance in the Growth and Sustainment Stages of the Cluster Lifecycle

Crack Growth Life Estimating for MSD Panel

The problem of multiple site damage (MSD) has got more attention in ageing structures. Cumulative effects of interacting cracks may significantly degrade the damage tolerance capacity of structures. Cracks caused by MSD are extremely difficult to detect and greatly reduce the residual strength, fatigue life and overall structural integrity of aircraft panels. This paper presents a simple numerical method, which use the principles of fracture mechanics and the computation results, to predict the fatigue crack growth life of MSD structure. Comparing with calculating crack growth life cycle by cycle, this method will save much time. To verify the validity of the proposed method, experiment was conducted and reported with simulation specimen of representative MSD structure with 5 details. The comparison between the calculated a-N curves and the crack growth lives and the test results shows that the prediction result with this fast method is acceptable. A discussion was carried out by numerical analysis; in with typical MSD structures with different initial crack length were adopted. Crack interaction effect was found obviously, but it occurred mainly in the last part of the crack growth lives. The relative size of MSD cracks depends significantly on the distribution of the initial cracks.

Lifecycles and crisis points in SMEs: a case approach

Reports on a study of the business activities and the emergence of the learning of marketing skills by eight entrepreneurial small businesses: four in the British Isles and four in the mid‐west of the USA. Using a qualitative methodology, a case approach is taken to study the obstacles to growth in a sample of these firms. Details these obstacles and reports how such obstacles were negotiated and overcome, enabling the firms to continue on the entrepreneurial growth curve. Also examines the nature of marketing development as a company grows from a small business to a medium‐sized one. Offers observations and conclusions on lifecycle growth in SMEs. As a small business reaches a given size where the costs of its internal administration and selling activities make it less viable, the SME is forced to look for new ways of growing through additional financial help, broadening its customer base and developing greater skills at corporate presentation.

Optimal Taxation in Life-Cycle Economies

We use a very standard life-cycle growth model, in which individuals have a labor-leisure choice in each period of their lives, to prove that an optimizing government will almost always find it optimal to tax or subsidize interest income. The intuition for our result is straightforward. In a life-cycle model the individual's optimal consumption–work plan is almost never constant and an optimizing government almost always taxes consumption goods and labor earnings at different rates over an individual's lifetime. One way to achieve this goal is to use capital and labor income taxes that vary with age. If tax rates cannot be conditioned on age, a nonzero tax on capital income is also optimal, as it can (imperfectly) mimic age-conditioned consumption and labor income tax rates.

The Consumption Tax and the Saving Elasticity

It is often assumed that if an income tax is converted to a consumption tax, the resulting change in the capital/labor ratio of the economy depends on the saving elasticity (the response of individual saving to the interest rate). In one standard life-cycle growth model, we show that, though this is correct in the short run, it is incorrect in the long run: conversion to a consumption tax always raises the steady-state capital/labor ratio, and the increase is the same regardless of the saving elasticity (positive, zero, or negative). In this model, a particular steady state is compatible with very different saving elasticities.

Role of akinetes in the development of cyanobacterial populations in the lower Murray River, Australia

Planktonic populations and benthic resting stages (akinetes) of the common bloom-forming cyanobacteria Anabaena circinalis Rabenhorst and Anabaena flos-aquae f. flos-aquae (Lyngb.) Komárek were monitored in the Murray River near Nildottie and in adjacent floodplain wetlands (lagoons) from 1995 to 1997, to determine the extent of sporulation and the contribution of recruitment from the sediments to seasonal development of blooms. Physical and chemical characteristics of the water in the river and the lagoons were examined in relation to the succession of key life-cycle stages and growth. The warm, shallow lagoons supported considerably higher populations of Anabaena in the summer than did the river, with correspondingly higher incidence of sporulation. Viable akinetes were abundant in the sediments of both the river channel and the lagoons, providing a potentially significant inoculum for cyanobacterial growth. The apparent germination of akinetes early in summer and immediately following sporulation in mid summer indicated a strategy for both initiation and maintenance of populations. A. circinalis also persisted as a planktonic population throughout winter. Germination is considered more likely to occur in the shallow lagoons than in the main channel, principally because of frequent resuspension of sediments containing resting stages to the euphotic zone or because of direct penetration of light to the sediments.
