    Designing biodiversity conservation policies requires not only estimating social benefits but also confirming that results exhibit sensitivity to scope — a necessary methodological condition for validity. This means that willingness to pay (WTP) should increase monotonically with the size or quantity of the goods. This study evaluates that effect in the economic valuation of biodiversity conservation in Manu National Park, Peru, based on specific attributes. A total of 2,240 choice experiments were conducted with household heads in Lima through face-to-face surveys, and logit models were applied to estimate marginal WTP. Results show that the most valued attributes are reducing endangered plant species (PEN 5.08/month) and reducing deforestation (PEN 4.69/month); however, no attribute showed sensitivity to range. Latent class analysis identified two heterogeneous preference groups regarding biodiversity conservation in this protected area. The “pro-conservation” group (78.3%) assigned positive and significant values to all attributes except the reduction from 24 to 8 endangered fauna species. This lack of scope sensitivity may stem from Peru’s status as a megadiverse country, where the inherent non-use value of biodiversity alone could justify in situ conservation policies involving modest costs for relatively few species or specific charismatic habitats.

    POLICY DISCLOSURE AS A PREDICTOR OF ENVIRONMENTAL BEHAVIOUR: EVIDENCE FROM THE CHILEAN RETAIL SECTOR
    This study examines the relationship between corporate environmental policy disclosures and firms' environmental investments. Using an endogenous switching probit (ESP) model to mitigate potential endogeneity issues, this study serves two purposes. Initially, it estimates the influence of six organizational characteristics-size, age, manager gender, export orientation, family ownership, and corporate group affiliation-on the probability of firms declaring pro-environmental policies. Subsequently, we test whether such policy disclosures are reliable predictors of environmental investment. We use the retail sector as a case study because of its pivotal role as an intermediary between primary producers, manufacturers, and consumers, thereby holding a uniquely influential position in driving sustainable consumption and production. Our results show a positive relationship between size, manager gender, export orientation, family ownership, and corporate group affiliation. In addition, we find that declaring an environmental policy positively affects the likelihood of businesses investing in environmental protection. This study contributes to the existing literature in three significant ways: it increases the evidence supporting a causal relationship between environmental policy disclosure and environmental investments; it is the first to explore this relationship within the retail industry; and it broadens our understanding of this dynamic in the context of developing countries.

    <jats:title>Abstract</jats:title><jats:p>Stated preference approaches, such as contingent valuation, focus mainly on the estimation of the mean or median willingness to pay (WTP) for an environmental good. Nevertheless, these two welfare measures may not be appropriate when there are social and political concerns associated with implementing a payment for environmental services (PES) scheme. In this paper the authors used a Bayesian estimation approach to estimate a quantile binary regression and the WTP distribution in the context of a contingent valuation PES application. Our results show that the use of other quantiles framed in the supermajority concept provides a reasonable interpretation of the technical nonmarket valuation studies in the PES area. We found that the values of the mean WTP are 10–37 times higher than the value that would support a supermajority of 70 per cent of the population.</jats:p>

    Understanding the role of institutions and economic context on entrepreneurial value creation choice
    <jats:p>Research background: The observable discrepancies in entrepreneurship activity across countries have motivated both researchers and policymakers to comprehend the sources of these variations. Certain scholars have suggested that the answer to this empirical puzzle lies in the macrolevel processes that influence entrepreneurial endeavours. Purpose of the article: As the understanding of macrolevel processes that shape entrepreneurial behaviour is limited, this research aims to answer how institutions and the economic context influence entrepreneurial value creation choices (i.e., for-profit, non-profit, and mixed). Methods: Using a cross-country sample of 7,891 entrepreneurs in 58 countries, we employ a multilevel ordered probit to evaluate a novel conceptual framework. Our analysis models the direct impact of the regulative framework, the normative pillar, and the cultural pillar, alongside the moderating influence of income inequality and economic uncertainty on value creation choices. Findings &amp; value added: Our findings show that the regulative framework has a positive marginal effect on for-profit and mixed-value creation, but a negative effect on non-profit value creation. Meanwhile, the normative pillar has a negative marginal effect on for-profit and mixed-value creation, but a positive effect on non-profit value creation. The cultural pillar has a negative marginal effect on for-profit and mixed-value creation, but a positive effect on non-profit value creation. Furthermore, income inequality moderates positive the relationship between normative pillar and for-profit and mixed-value creation, while economic uncertainty moderates negative the relationship between normative pillar and for-profit and mixed-value creation. Our research contributes to the literature by providing a nuanced understanding of how institutional pillars can act as drivers or barriers for different entrepreneurial forms, evidence of how uncertainty interacts with institutional forces to shape value creation decisions, and insights into the distinctive attributes of different entrepreneurial forms. Our findings have implications for public policy development.</jats:p>
