  • The Macroeconomic Loss Due to Violence against Women and Girls


    Working Paper No. 939 | October 2019
    The Case of Ghana
    Violence against women and girls (VAWG) is a widely recognized human rights violation with serious consequences for the health and well-being of women and their families. However, the wider ramifications of VAWG for businesses, communities, economies, and societies are only recently being recognized. Despite this recognition, there are few studies exploring how the economic and social impacts of VAWG affect economic growth, development, and social stability. In this paper, applying the social accounting approach, we outline the ripple effects of VAWG from the individual micro-level impacts to the macroeconomy. Our analysis shows the loss due to VAWG amounts to about 0.94 percent of Ghanaian GDP and is a permanent invisible leakage from the circular flow of the economy. The analysis also shows that the loss due to violence is not just a one-off leakage from the macroeconomic circular flow and explores the potential consequences of the multiplier loss due to VAWG over a period of time. The cumulative loss is sizeable and inflicts a premium on GDP growth over time—in simple terms, inaction today in addressing VAWG for cost considerations will impose a larger cost premium on economic growth, which will constrain tomorrow’s resources.

  • Macroeconomic and Microeconomic Impacts of Improving Physical and Social Infrastructure


    Research Project Report, September 2019 | September 2019
    A Macro-Micro Policy Model for Ghana and Tanzania
     
    Feminist economics has long emphasized the role of physical and social infrastructure as determinants of the time women spend on household production (the provision of unpaid domestic services and care). Surprisingly, there is a lack of studies that directly investigate how infrastructure improvements affect the time spent on household production and commuting to work, which is another important unpaid activity for most employed individuals. We attempt to fill the lacunae in the research by studying this issue in the context of Ghana and Tanzania utilizing the framework of the Levy Institute Measure of Time and Income Poverty. Separately, while there are several studies (including those done previously at the Levy Institute) on the macroeconomic impacts of government expenditures on care, these assessments tend to be based primarily on employment multipliers along with simple macroeconomic assumptions. We develop a disaggregated and fully articulated macroeconomic model based on the social accounting matrices for the two countries to take account of the intersectoral linkages and external constraints, such as balance of payments, that are particularly important for many developing nations, including Ghana and Tanzania. The macro- and microeconomic aspects are integrated in a unified analytical framework via a top-down disaggregated macroeconomic model with microsimulation that is novel in that it enables the investigation of the gendered economic processes and outcomes at the macroeconomic and microeconomic levels.

  • From Unpaid to Paid Care Work


    Working Paper No. 570 | July 2009
    The Macroeconomic Implications of HIV and AIDS on Women's Time-tax Burdens

    This paper considers public employment guarantee programs in the context of South Africa as a means to address the nexus of poverty, unemployment, and unpaid work burdens—all factors exacerbated by HIV/AIDS. It further discusses the need for genderinformed public job creation in areas that mitigate the “time-tax” burdens of women, and examines a South African initiative to address social sector service delivery deficits within the government’s Expanded Public Works Programme. The authors highlight the need for well-designed employment guarantee programs—specifically, programs centered on community and home-based care—as a potential way to help offset the destabilizing effects of HIV/AIDS and endemic poverty. The paper concludes with results from macroeconomic simulations of such a program, using a social accounting matrix framework, and sets out implications for both participants and policymakers.

  • Hypothetical Integration in a Social Accounting Matrix and Fixed-price Multiplier Analysis


    Working Paper No. 552 | December 2008

    This study proposes a simple modification to a Social Accounting Matrix (SAM) in order to analyze the multiplier effects of a new sector. A different input composition, or technology, of the sector makes a conventional analysis of final-demand injections on existing sectors invalid. Author Kijong Kim shows that the modification—so-called hypothetical integration—is an efficient way to incorporate the difference into the SAM, rather than costly full-scale rebalancing. He applies this method to the case of the Expanded Public Works Programme in South Africa, and demonstrates that the proposed approach effectively represents the labor intensity requirement of the program and a new-factor income distribution.
