Demand Variation

COVID-19 disease shocked global economic activity and affected the electricity markets due to lockdown and work-from-home policies. Therefore, this study proposes an empirical analysis to identify the electricity spot price response during the preventive and mandatory insulation in Colombia, where the economic contraction caused the largest decrease in the electricity demand, especially in the industrial sector. The methodology applied was quantile regression to quantify the non-linear effect on the spot price returns, and two sample periods were selected to contrast the results: 2018 and 2019. The main findings showed that regulated demand variation caused the highest variability on the spot price dynamic during the strict quarantine. However, the price could not fully capture the effects of the demand change due to the short duration of the shock and, also, the price variability in 2019 was higher than 2020 by an El Niño shock.

A Site

In the COVID-19 pandemic, people’s dwellings suddenly became a predominant site of economic activity. We argue that, predictably, policy-makers and employers took the home for granted as a background support of economic life. Acting as if home is a cost-less resource that is free for appropriation in an emergency, ignoring how home functions as a site of gendered relations of care and labour, and assuming home is a largely harmonious site, all shaped the invisibility of the imposition. Taking employee flexibility for granted and presenting work-from-home as a privilege offered by generous employers assumed rapid adaptation. As Australia emerges from lockdown, ‘building back better’ to meet future shocks entails better supporting adaptive capabilities of workers in the care economy, and of homes that have likewise played an unacknowledged role as buffer and shelter for the economy. Investing in infrastructure capable of providing a more equitable basis for future resilience is urgent to reap the benefits that work-from-home offers. This article points to the need for rethinking public investment and infrastructure priorities for economic recovery and reconstruction in the light of a gender perspective on COVID-19 ‘lockdown’ experience.

Economic Outlook

If I were an Irishman, I should find much to attract me in the economic outlook of your present government towards greater self-sufficiency. (J.M. Keynes)The 1930s were years of political turmoil and economic crisis and change in Ireland. Economic activity had peaked in 1929, and the last years of the Cumann na nGaedheal government (in power since the establishment of the Irish Free State in 1922) saw substantial drops in output, trade and employment. The policies pursued after Fianna Fáil’s victory in the election of February 1932 were therefore influenced both by immediate economic pressures and by the party’s ideological commitments. The highly protectionist measures associated with de Valera and Lemass — key men of the new régime — sought both to create jobs quickly and to build more gradually a large indigenous industrial sector, producing primarily for the home market.Political controversy complicated matters. De Valera was regarded as a headstrong fanatic by the British establishment. His government’s refusal to hand over to Britain the so-called ‘land annuities’ — a disputed item in the Anglo-Irish settlement of 1921 — led to an ‘economic war’, in which the British Treasury sought payment instead through penal ‘emergency’ tariffs on Irish imports. The Irish imposed their own duties, bounties and licensing restrictions in turn. The economic war hurt Irish agriculture badly; the prices of fat and store cattle dropped by almost half between 1932 and mid-1935. Farmers got some relief through export bounties and the coal-cattle pacts (quota exchanges of Irish cattle for British coal) of 1935-7, but Anglo-Irish relations were not normalised again until the finance and trade agreements of the spring of 1938, and the resolution of the annuities dispute did not mean an end to protection. The questions ‘Who won the economic war?’ and ‘What was the impact of protection on the Irish economy?’ are analytically distinct, but they are not that easy to keep apart in practice.

Optimization And Simulation

The VIRTUS project aims to create a Virtual Power Plant (VPP) prototype coordinating the Distributed Energy Resources (DERs) of the power system and providing services to the system operators and the various players of the electricity markets, with a particular focus on the industrial sector agents. The VPP will be able to manage a significant number of DERs and simulate realistic plants, components, and market data to study different operating conditions and the future impact of the policy changes of the Balancing Markets (BM). This paper describes the project’s aim, the general structure of the proposed framework, and its optimization and simulation modules. Then, we assess the scalability of the optimization module, designed to provide the maximum possible flexibility to the system operators, exploiting the simulation module of the VPP.

Refined Classification

In this study, we investigate the subtle temporal dynamics of California 1999–2000 spot price series based on permutation min-entropy (PME) and complexity-entropy causality plane. The dynamical transitions of price series are captured and the temporal correlations of price series are also discriminated by the recently introduced PME. Moreover, utilizing the CECP, we provide a refined classification of the monthly price dynamics and obtain an insight into the stochastic nature of price series. The results uncover that the spot price signal presents diverse temporal correlations and exhibits a higher stochastic behavior during the periods of crisis.

Lockdowns imposed around the world to contain the spread of the COVID-19 pandemic are having a differential impact on economic activity and jobs. This paper presents a new index of the feasibility to work from home to investigate what types of jobs are most at risk. We estimate that over 97.3 million workers, equivalent to about 15 percent of the workforce, are at high risk of layoffs and furlough across the 35 advanced and emerging countries in our sample. Workers least likely to work remotely tend to be young, without a college education, working for non-standard contracts, employed in smaller firms, and those at the bottom of the earnings distribution, suggesting that the pandemic could exacerbate inequality. Crosscountry heterogeneity in the ability to work remotely reflects differential access to and use of technology, sectoral mix, and labor market selection. Policies should account for demographic and distributional considerations both during the crisis and in its aftermath.
