Income tax breaks for elderly taxpayers are sizable, widespread, and potentially affect growth through migration and other behaviors. We provide the first investigation into the growth effects of differential tax policy by age, taking a multi-pronged empirical approach to US state-level data since 1977. Some analyses include panel error-correction models combined with variation in state-level policies over time. Alternative analyses use how changes in federal tax law manifest at the state-level. Results suggest that taxes on lower income taxpayers, of any age, decrease growth the most, while taxing the high income elderly—those targeted recently—has little effect.  相似文献

This paper reviews recent educational initiatives in science, technology, engineering and math (STEM) education in the United States, asking to what extent experiential learning methods are being incorporated into STEM education. We draw on a combination of qualitative and quantitative evidence. The quantitative evidence is from an analysis of the proposal abstracts for all 11,406 of the STEM education and workforce development-related projects funded by NSF grants from the end of 2018 to the beginning of 2022. The qualitative portion of the paper analyzes results from a number of scholarly studies of local initiatives from the last 10 years drawn from a range of published and conference papers, reports and media stories, and project websites, drawn from education research databases, secondary literature, and websites of specific organizations. We seek to classify and describe patterns observed among the projects examined, identifying common patterns and combinations of features. We believe that the paper represents the first comprehensive study of efforts to employ experiential learning methods in STEM education to link formal and informal aspects of learning.  相似文献

Feedback withdrawal mechanisms in online markets aim to facilitate the resolution of conflicts during transactions. Yet, frequently used online feedback withdrawal rules are flawed and may backfire by inviting strategic transaction and feedback behavior. Our laboratory experiment shows how a small change in the design of feedback withdrawal rules, allowing unilateral rather than mutual withdrawal, can both reduce incentives for strategic gaming and improve coordination of expectations. This leads to less trading risk, more cooperation, and higher market efficiency.  相似文献

The interest-minimizing strategy to paying multiple debts is to make all minimum payments and allocate remaining funds to the debt with the highest interest rate. However, cognitive biases such as debt account aversion and financial advisors encourage borrowers to instead allocate remaining funds to debts with lower outstanding balances, a strategy known as the Debt Snowball. The author uses the 2016 Survey of Consumer Finances to quantify the pecuniary costs for American households of following the Debt Snowball and finds that the average household pays an additional 1.8%–4.3% in interest, leading to an aggregate transfer of wealth from borrowers to lenders of between $46.2 and $53.9 billion in excess of what would occur if borrowers instead minimized interest accrual. Due to differences in household debt structure, the Debt Snowball strategy imposes greater pecuniary penalties on low-income households, on Black households, and on households with more initial debts.  相似文献

As research on venture accelerators develops, different models have emerged in the literature. These focus on the goals of the accelerator, which range from creating profit for managers and building support for business platforms to promoting regional economic development, as well as on its organizational form based on its for-profit or non-profit status. This article examines a novel model, the networked venture builder model, which offers an alternative perspective on the acceleration process. Using the example of the Alacrity Global Ecosystem (AGE), this article explores how the venture builder model includes characteristics of multiple accelerator types, which has helped it both rapidly grow new ventures and achieve substantial economic development goals. Synergies between the different aspects of the AGE’s organizational design help it support multiple missions. Drawing on interviews with key stakeholders and entrepreneurs within the AGE, this article describes the history of the AGE and its present form, providing new insights into a novel, but increasingly common, accelerator design and laying the basis for further research on its emerging organizational form.

Over the last four decades, the relative price of investment goods in Africa has gone through a relatively large decrease, resulting in a steady convergence towards the levels recorded in high-income countries. This fact begs the following question: To what extent might the relative price decrease be a driving force behind the economic performance of this continent? The paper addresses this question from the perspective of a panel ARDL approach, using the Solow growth model—augmented with barriers to investment—as a framework. The results reveal that a one-unit decrease in the relative price of investment leads, in the long term, to a 4% increase in per capita GDP, an increase that could be neutralised by a 6.5 percentage points decrease in the savings rate. The findings contribute to the case for a policy mix that combines policies geared towards reducing investment distortions with those promoting savings mobilisation.  相似文献
