However, we show that by ignoring genuine uncertainty and by assuming that profits follow an objectively true and ex ante known probability distribution, the entrepreneur is made redundant. Thus, the theory fails to exhaustively explain innovation, the role of ownership competence, profits, the function of financial markets, wealth and income distribution, and, ultimately, economic growth. These shortcomings risk leading to erroneous or overly narrow policy conclusions by overestimating the importance of supporting R&D investments. Rather, the presence of genuine uncertainty forms a fundamental theoretical basis for the importance of new venture creation as a source of innovation-driven growth; entrepreneurs must establish and expand firms to capture the subjectively perceived profit opportunities. Therefore, tax policy is decisive for the commercialization and dissemination of innovations by providing incentives to uncertainty-bearing, not only for entrepreneurs, but also for intrapreneurs and financiers taking an active part in the governance and development of firms based on innovations characterized by genuine uncertainty. Furthermore, taxation can distort the evolutionary selection of innovations and firms, for instance, by taxing owners and firms differently.","PeriodicalId":21803,"journal":{"name":"Small Business Economics","volume":"59 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143049975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While research suggests that regions benefit economically from a high concentration of niche market leaders, it is still unclear which role locating close to one another plays for their innovation performance. Therefore, we contribute to existing literature that studies external factors of firm-level innovation. We analyze 1372 German niche market leaders and study whether (1) being located in a cluster improves their innovation performance and (2) if the impact of locating in a cluster varies depending on the diversity of industries within the cluster. We measured the spatial agglomeration using the location quotient. Our findings show that being located in a cluster increases the patenting rate by 1.49 times. This effect is more pronounced in clusters with more diverse industries, indicating a lower level of technology specificity. This suggests that technology specificity has an impact on a company’s ability to take advantage of positive knowledge from other companies in the same cluster. Finally, we conducted several tests to ensure the robustness of our analysis. The Modifiable Areal Unit Problem (MAUP) refers to the discretionary choice of the spatial unit, and we tested different spatial unit levels to account for this. Additionally, we used entropy balancing to confirm the positive effect of cluster location on innovation, comparing with a control set of mass-market firms. Our study concludes with implications for both corporate management and public policy.","PeriodicalId":21803,"journal":{"name":"Small Business Economics","volume":"7 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143044113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important issue in the transformation process of agricultural production is the role of small farms. While many authors have looked at this question, one aspect that has received little attention is the role of small farms in the production of nutritious foods, an important topic given the low availability and relatively high prices of nutritious foods and the consequent low level of nutrition security in the continent. Using a unique large‐scale dataset from Ethiopia—one of the largest countries in Africa that has been transforming rapidly—we look at the production of vegetables and dairy products. We find a strong association between farm size and partial productivity measured in terms of output, value of outputs and profit per hectare/cow, with productivity twice to four times as high for larger farms. These farms have substantially higher input expenditures as well as differences in farm technologies compared to small ones. Our findings have important implications for the debate on the role of small farms and nutritional improvements in the continent.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"145 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030739","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}

This is particularly so in lower- and middle-income countries where land is the principal basis of livelihoods and generates substantial but diverse ecosystem services, and tenure arrangements affect both livelihoods and ecosystem provision simultaneously. Despite decades of research on LSLTs, a significant epistemological gap persists between broad quantitative analyses and in-depth case studies, and systematic empirical research investigating the joint economic, social, and environmental outcomes remains rare. We analyze 24 LSLTs in Ethiopia, selected carefully to represent variations in LSLT characteristics and local contexts. Across these 24 cases, outcomes diverge markedly from the pessimistic conclusions identified in much existing empirical research. Considering such diversity, we classify LSLT outcomes into four categories: synergy, tradeoff, struggle, and failure. We then perform qualitative comparative analysis to examine the specific conditions that correlate with these outcomes. Our findings highlight the importance of moving beyond monoconsequential predictions for land tenure changes and of more comparative analysis of LSLTs to attend to variations across social, economic, and environmental outcomes considered in relation to each other. An integrated epistemological approach, our study shows, is necessary to understand the diverse pathways through which land tenure changes drive human-nature interactions and affect the broader landscape of coupled socio-ecological systems.","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":"138 46 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143031441","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}
