We analyze Chinese listed firms (2010–2018) using a Crépon–Duguet–Mairesse recursive framework, a three-equation causal chain that links regulation, innovation, and productivity. We find that a variety of environmental policies raise compliance costs, crowding-out average R&D investment. Non-green innovation yields higher productivity returns in low-pollution firms and exhibits a U-shaped return pattern across the productivity distribution, whereas green innovation's returns follow an inverted-U-shaped profile, peaking at medium-high productivity—where, for high-pollution firms, they exceed those of non-green innovation, boosting TFP. These results provide mechanism-based evidence for the strong Porter hypothesis as a context-dependent reconfiguration of technological and productive efficiency under regulatory stimuli. Policy support for green innovation should be targeted at high-pollution, mid-to-high-productivity firms based on verifiable outcomes, turning the crowding-out of R&D into productive reallocation.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"155 ","pages":"Article 107418"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145789950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explore hybrid dynamic stochastic general equilibrium (DSGE)-agent-based modeling (ABM) macrodynamics in which firms periodically revise (and possibly switch) pricing strategies. Firms choose a pricing heuristic from a set of alternatives encompassing a cost-based heuristic with a standard markup, a cost-based heuristic with a quality-adjusted markup, and a heuristic of following competitors’ pricing behavior. For illustration, we employ a simulated method of moments to calibrate the model with quarterly data for the United States. The model qualitatively replicates several empirical facts about firms’ strategic pricing behavior, particularly with respect to the frequency and magnitude of price adjustments. Two key findings are price stickiness and persistent heterogeneity in pricing behavior, with no single pricing rule becoming dominant. A local sensitivity analysis was conducted on selected key micro-level and macro-level parameters, with results indicating that price stickiness and persistent heterogeneity in firms’ pricing behavior are driven by a combination of both micro- and macroeconomic factors. Embedding some tenets of the ABM approach such as introducing heterogeneous firms evolutionarily learning and adapting to the environment into the DSGE model enables us to qualitatively reproduce the persistent heterogeneity in pricing behavior across firms without compromising its ability to reproduce several stylized macroeconomic facts. A key broad policy implication is that the microdiversity and macrodynamics of the economy are inherently co-evolutionary phenomena.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"155 ","pages":"Article 107387"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145537070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While prior studies have focused primarily on traditional policy instruments and firm-level characteristics, the role of place-based digital policies in fostering corporate DTI remains insufficiently understood. Exploiting the establishment of national new-generation artificial intelligence innovation and development pilot zones (AIPZs) in China as an exogenous policy shock, and using a sample of Chinese A-share listed firms, we employ a multi-period difference-in-differences approach to identify the causal effect of the AIPZs policy on corporate DTI. The results show that the AIPZs policy significantly enhances firms' digital technology innovation. This effect is further strengthened by firms' digital transformation and executives’ digital backgrounds and operates through increased R&D investment, improved human capital, and reduced operating costs. Overall, these findings provide empirical evidence on the effectiveness of place-based digital policies and deepen our understanding of policy-driven digital innovation ecosystems.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"155 ","pages":"Article 107459"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145883711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using an overlapping generations (OLG) model with endogenous longevity, we examine how environmental conditions influence the effectiveness of green taxes. A key endogenous mechanism links changes in environmental quality to the economy through health effects, shaping the policy–environment boundaries for dynamics and output maximization. The model predicts that regions with low environmental carrying capacity (ECC) and low green tax rates will experience environmental and economic cycles, leading to intergenerational inequality, and fail to maximize output. These cycles can be avoided, and output maximized, if such regions raise their green tax rates. By contrast, in regions with higher ECC, the green tax rate that maximizes output may not eliminate cycles. Our findings provide insights into two dimensions of compatibility: (1) the alignment between policy stringency and environmental conditions, and (2) the compatibility of policy objectives aimed at eliminating cycles and maximizing output.</div></div>","PeriodicalId":48419,"journal":{"name":"Economic Modelling","volume":"155 ","pages":"Article 107415"},"PeriodicalIF":4.7,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145684379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their combined labour market <em>effects</em> have not been estimated so far. We feed all three intensities into the theoretical framework of a labour market matching function to estimate their impact on the job finding rate – effects which are not settled a priori.

For measuring the search and placement intensities, we use big data on online activity obtained from the job exchange of the German Federal Employment Agency and from its internal placement-software. The results show that all three intensities significantly contribute to the variation in job findings beyond vacancies and unemployment.
