Degrees of Displacement: The Impact of Household PV Battery Prosumage on Utility Generation and Storage

Reductions in the cost of PV and batteries encourage households to invest in PV battery prosumage. We explore the implications for the rest of the power sector by applying two open-source techno-economic models to scenarios in Western Australia for the year 2030. Household PV capacity generally substitutes utility PV, but slightly less so as additional household batteries are installed. Wind power ...

The Accumulation of Wealth in Marriage: Over-Time Change and Within-Couple Inequalities

This study examines the accumulation of personal wealth of husbands and wives and investigates the development of within-couple wealth inequalities over time in marriage. Going beyond previous re- search that mostly studied the marriage wealth premium using household-level wealth data and that conceptualized marriage as an instantaneous transition with uniform consequences over time, we argue that ...

The Economic Costs of Hybrid Wars: The Case of Ukraine

With more than ten thousand casualties, the ongoing hybrid Ukrainian war between pro-Russian separatists and the government in the Donbass region, Ukraine’s productive core, has taken a severe toll on the country. Using cross-country panel data over the period 1995–2017, this paper estimates the causal effects of the Donbass war on Ukraine’s GDP. Our counterfactual estimation by the synthetic control ...

Hartz and Minds: Happiness Effects of Reforming an Employment Agency

Since the labor market reforms around 2005, known as the Hartz reforms, Germany has experienced declining unemployment rates. However, little is known about the reforms’ effect on individual life satisfaction of unemployed workers. This study applies difference-in-difference estimations and finds a decrease in life satisfaction after the reforms that is more pronounced for male unemployed in west Germany. ...

Global Economy: Slow Recovery Following Deep Recession: DIW Economic Outlook

The coronavirus pandemic caused a global market crash in the first half of 2020. Following a massive slump of around four percent in the first quarter, global GDP decreased in the second by five percent. Lower rates of new infections, together with far-reaching monetary and fiscal policy measures to dampen the economic impact of the pandemic, ensure that production and the trust of consumers and firms ...

German Economy: On the Long, Slow Road to Normality: DIW Economic Outlook

The German economy has bottomed out, but its recovery is going to be long and arduous. Nevertheless, following the almost two-digit slump in economic output in the second quarter of 2020, recovery is likely to be accompanied by above-average rates. However, it is assumed that a second wave will not occur and lockdown-like measures will not be reimplemented. Private consumption in particular will markedly ...

Center-Based Care and Parenting Activities

We estimate effects of center-based care on parenting activities using time use data for Germany. Our estimates imply that center-based care reduces the overall time that parents spend with the enrolled child, but has only small negative effects on time spent doing activities together. Correspondingly, center-based care increases activities as a share of the time spent together with the child. The ...

US and EU secure vaccine production on home soil

The deployment of a safe and effective vaccine for Covid-19 will be central to lifting containment measures. In a bid to speed up vaccine deployment, governments are entering into ‘Advance Purchase Agreements’ (APAs) with vaccine companies to secure access to vaccine doses. We document and compare the vaccine procurement strategies of the US and the EU. Most notably, we find that both...
