This paper uses a reform in Illinois that reduced the monthly subsidy offered to relatives asked to provide foster care as a plausibly exogenous change in the cost of caring for related children. Families offered a 30% lower wage were 15% less likely to provide care, with especially large declines for children who require mental health services, infants and teenagers. One innovation is a sample...

This paper exploits the introduction of a pro-natalist transfer policy in the Canadian province of Quebec that paid up to C$8,000 to families having a child. I implement a quasi-experimental strategy by forming treatment and control groups defined by time, jurisdiction, and family type. The incentive was available broadly, rather than to a narrow population as studied in previous work, providin...

Distributed generation with solar photovoltaic (PV) technology is economically competitive if net metered in the U.S. Yet there evidence that metering misrepresenting true value of distributed so (VOS) becoming preferred method for evaluating economics grid-tied PV. VOS calculations are challenging and widespread disagreement literature on methods data needed. To overcome these limitations, thi...

Previous models of growers' decision-making during epidemics have unrealistically limited disease management choices to just two options. Here, we expand previous game-theoretic grower include three control options: a crop that is tolerant, resistant or susceptible disease. Using tomato yellow leaf curl virus (TYLCV) as case study, investigate how growers can be incentivized use different optio...

This article attempts to evaluate the My Electricity program concerning increasing renewable energy production in photovoltaic (PV) prosumer sources (PV micro-installations) Poland. The assessment is made from perspective of beneficiaries, business, and local community. One may also find an answer question how this should be modified so that it continues support development PV systems Moreover,...
