Estimating the economic costs of electricity deficit using input–output analysis: the case of Brazil

The objective of this article is to present a methodology to estimate the marginal cost of electric energy deficit in the long-term using input–output (I–O) analysis. We obtain a deficit marginal cost (DMC) curve that is not limited to a small number of levels, such as the curve used currently in Brazil, which is limited to four levels. The marginal cost of deficit is an important exogenous parameter used in the model’s chain to calculate the operation’s marginal cost and short-term market pricing. The electric energy deficit is a temporary lack of continuity in meeting demand, which is usually predictable and involves prior notice to the consumer. The cause of this deficit may be a lack of investment and/or low water inflows that impact the production of hydroelectric power plants. In this study, the marginal cost of the deficit is obtained from restrictions on the provision of electricity for productive sectors and by calculating the corresponding impact on the gross domestic product. The proposed methodology can be used with data from the I–O matrix of any country to estimate its marginal cost of electric energy deficit.     

The financial and green effects of cultural values on mission drifts in European social enterprises

The sustainable social enterprises (SEs) literature shows that SEs have to simultaneously pursue economic, social, and environmental aims. However, tensions between these objectives can make this a challenging task and lead towards mission drift. This work investigates if the cultural dimension can forecast the mission drift. We empirically analyze this relationship in three stages. In the first stage, we identify a homogeneous dataset of 287 sustainable SEs from seven EU countries from 2011 to 2020. Then, in the second stage, we apply the data envelopment analysis (DEA) methodology to calculate the efficiency of the SEs. An efficient SE has to simultaneously achieve social, environmental, and economic aims. We calculate a proxy of the mission drift and generate a dichotomous category variable that assigns value 1 to the SE not affected by mission drift, 0 otherwise. In the last stage, we implement the 2SLS logistic regression between the variable that identifies the SEs affected by mission drift and three cultural dimensions: avoidance of uncertainty, masculinity, and short-term orientation.
