Abstract: The adoption of green technology in developing countries is essential for sustainable development. However, willingness-to-pay (WTP) for green technology remains low in many of these regions. Traditional WTP assessments do not adequately capture the complexities of credit-based purchases, where payments are distributed over time and agents are time-inconsistent and credit-constrained. This study outlines a novel theoretical framework to evaluate WTP for credit-based purchases in Kenya, focusing on an affordable clean energy solution - portable solar lamps. Utilizing the Bayesian Adaptive Choice Experiment (BACE), this study evaluates small business owners' WTP for credit-based purchases of solar lamps by varying down payment and repayment amounts. Exploiting a randomized controlled trial (RCT) that offers owners a traditional subsidy on the down payment or a proposed tailored subsidy where an equivalent amount of subsidy is applied on the down payment or the repayment,  this study examines the impact on small business owners' adoption and business performances. By understanding how small business owners value credit purchases, we can better design and implement green technology initiatives and subsidy policies targeting similar clean-energy products to promote sustainable energy transitions in the developing world.

Abstract: Local politicians are essential in allocating public resources and managing regional economic activities, particularly within decentralized systems. Existing studies have extensively documented evidence of hometown favoritism influencing investment activities and the distribution of public goods. However, there is scant evidence regarding the influence of local favoritism on the allocating public bads. This paper investigates the impact of local regulators' hometown favoritism on pollution regulation, firm pollution responses, and performance in China's water pollution context. We use georeferenced data on polluting firms, matching them to prefectural city boundaries and river networks. Leveraging the hometown link variation across bordering areas within the same jurisdiction city caused by exogenous prefectural city leader turnover, we examine the differences in pollution response and performance between firms located upstream of local leaders' hometowns and those located upstream of non-hometown areas. We further consider the heterogeneity in local regulators' incentives and firm size.

Abstract: This paper examines how the new round of Land Certification Reform (LCR) in rural China that formalizes land use rights affects farmers’ rental market participation as well as their intra-household decisions about living arrangements and eldercare.  Exploiting the village-level staggered implementation, I find that this reform increases the likelihood of farmers renting out their land and therefore leads to a higher income. Also, elderly parents are less likely to coreside with and receive companionship from their children, especially sons, after the reform; this is mainly driven by landed households. Moreover, households subject to this reform are more likely to receive transfers from children and there is an overall positive impact on the net amount of transfers. I find no evidence that this reform affects the mental health of elderly parents.
