    Violence against women occurs predominantly in the family and domestic context. The Covid-19 (Sars-COV-2) pandemic led Brazil to recommend and, at times, impose social distance, with a partial closure of economic activities, schools, and restrictions on events and public services. As a result, there was an intensification of the presence of families in their residence. Preliminary evidence shows that intense coexistence increases domestic violence. At the same time, quarantine may have prevented access to public networks and services and deprivation of information and help. We propose an agentbased model (ABM), called VIDA, to illustrate and examine multi-causal factors that influence events that generate violence. The formalization of the effects allows testing the presence or absence of deterrence systems and increasing the intensity of the stay at home. A central part of the model reflects the creation of a multi-causal stress indicator, which functions as the probability of an attack occurring in the family environment. At the same time, a deterrent system based on reporting, requesting protection and accusing the perpetrator was implemented. VIDA was calibrated for the numbers of notifications of violence collected by the Federal Senate in 2011. After a sensitivity analysis, two tests are performed: i) absence or presence of the deterrence system and forced quarantine. VIDA presents orders of magnitude for Areas of concentration and weighting areas for these tests. VIDA indicates that quarantine may have increased violence against women by about 10%. The results of simulations with VIDA suggest that more populated sites have comparatively fewer attacks per hundred thousand women than less populous capitals or rural areas of urban concentrations. The paper’s contributions include the formalization of a model of domestic violence through agent-based modeling, which, it seems, does not exist in the literature, which illustrates socioeconomic, demographic, educational, gender and color factors, with detailed data at the intra-urban and for all major Brazilian population agglomerations. In addition, a whole process of generation of an artificial population for the simulation was created and is available, as well as all the model code, with free access, in a public repository, on the internet.

    We investigate the relationship between farm level competitiveness and environmental performance using Stochastic Frontier Analysis (SFA). We use an Irish panel of farm level financial data for the years 2000-2017 to analyse the link between EU Common Agricultural Policy environmental payments, and dairy and beef production from economic and environmental views. Our estimates identify a positive relationship between technical efficiency and environmental payments in place in recent years, although not for early versions of these payments. We simulate increases in the Green, Low-Carbon, Agri-Environment payments targeted to farms with low stocking rates, financed through reductions in decoupled payments. We find that under this stylised scenario, competitiveness and environmental gains are achieved for dairy farms. However, under this scenario, we do not identify gains for beef farms. We also find a reduction in income inequality under this scenario for both farm types.

    With an increasing number of electric vehicles, the strategic planning of public charging infrastructure becomes more important. In this work, the infrastructure of the charging stations in a large city is simulated. Here, various influencing factors such as number of users, charging time, charging frequency, type of the charging station and billing model are modified in order to obtain the optimal construction and operation of public charging infrastructure. The results illustrate conditions under which a system for public charging infrastructure becomes unstable as the number of users increases. In addition, it is shown, which measures should be used to improve the system characteristics. The results of the simulation reveal that with an increasing number of users a switch of the billing model can be more effective than the construction of additional charging station. Furthermore, it makes sense to construct distributed single charging points in a city at the beginning of the development phase and to switch to satellite systems with more charging points once the number of users has increased sufficiently.

    Understanding the economic and social effects of the recent global trends of rising market concentration and market power has become a policy priority. To fill this knowledge gap, this paper introduces a simple simulation method, the Welfare and Competition tool (WELCOM), to estimate with minimum data requirements the direct distributional effects of market concentration through the price channel. Using this simple yet novel tool, this paper illustrates the likely distributional effects of reducing concentration in two markets in Mexico that are known for their high level of concentration: mobile telecommunications and corn products. The results show that increasing competition from four to 12 firms in the mobile telecommunications industry and reducing the market share of the oligopoly in corn products would achieve a combined reduction of 0.8 percentage points in the poverty headcount as well as a decline of 0.32 points in the Gini coefficient.

    The recent boom in house prices in many countries during the Covid-19 pandemic and the possibility of household financial distress are of concern among some central banks. We revisit the empirical modelling of house prices and household debt with a policy-oriented perspective using Norwegian data over the last four decades within the cointegrated VAR model. Our findings suggest, in line with previous work, a long-run mutually reinforcing relationship between these financial magnitudes, and thus the potential for the build-up of financial instabilities and spillover effects to the real economy. Applying a control analysis, we find that both house prices and debt are controllable magnitudes to some pre-specified target levels through the mortgage interest rate, which enables the central bank to reduce large fluctuations and bubble tendencies in the housing market. The present control analysis thus provides some useful policy implications from empirically relevant representations of two important financial factors entering the decision process of the policy maker.

    Up-to-date, nationally representative household income/expenditure data are crucial to estimating poverty during the COVID-19 pandemic and to policy-making more broadly, but South Africa lacks such data. We present new pandemic poverty estimates, simulating incomes in prepandemic household surveys using contemporary labour market data to account for job losses between 2020 Q1 and 2021 Q4. Improving on much of the existing literature, we use observed rather than simulated shocks and allow for uneven impacts of the pandemic by employment sector and demographic characteristics. We present three updating methods, using the National Income Dynamics Study (NIDS) Wave 5, the Living Conditions Survey 2014/15, and the Quarterly Labour Force Survey (QLFS). Giving primacy to NIDS Wave 5 produces the largest estimate of pandemicperiod job-loss-induced poverty: a headcount ratio increase at the upper-bound poverty line of 5.2 percentage points (3.1 million people/13 per cent) and poverty gap increase of 3.8 percentage points (21 per cent). Giving primacy to QLFS data produces the lowest estimated change: a headcount ratio increase of 3.0 percentage points (1.8 million people/7 per cent) and poverty gap increase of 2.5 percentage points (12 per cent). Simulating receipt of the Special COVID-19 Social Relief of Distress social grant substantially mitigates poverty effects, with a poverty headcount increase of 1.1-3.4 percentage points and a poverty gap increase of 0.2-1.5 percentage points.

    Here we respond to a recent article in this journal by Leonardo Ambasciano, in which he offers a high-level critique of “big data,” artificial intelligence, and computational approaches in the study of religion. The main thrust of his argument is that these approaches are fundamentally problematic both because of their negative effect on the humanities and because they inappropriately rely on “neoliberal philanthrocapitalist” funding. In our response, we refer to our experience working with computational scientists and humanities scholars in collaborative teams, where they stand shoulder to shoulder in equal collaboration with one another, each side relying on the distinctive value that the other provides as they attempt to create clearer and more valid descriptions, analyses, and explanations of complex human behaviors. We correct several errors of fact in Ambasciano’s article, focusing first on ideological and ethical issues and then on methodological and epistemological issues. We conclude by emphasizing several points on which we agree with his assessment.

    We analyze persistence in marijuana consumption utilizing data from the 1997 cohort of the National Longitudinal Survey of Youth (NLSY97). We allow for three sources of persistence: pure state dependence, time invariant unobserved heterogeneity and persistence in idiosyncratic, time-varying shocks. We also consider intensity of consumption based on days of use per month and estimate a dynamic ordered Probit model using simulated Maximum Likelihood. We consider a Polya model that generalizes the more commonly used Markov models. The results show that there is a causal eect of previous use. However, ignoring unobserved heterogeneity and serially correlated shocks signicantly exaggerates the state dependence.
