title: Data and code for: Informed Enforcement: Lessons from Pollution Monitoring in China

description: This project provides the data and code accompanying the article "Informed Enforcement Lessons from Pollution Monitoring in China"<br><br>Abstract: Government regulations are often imperfectly enforced by public officials. In this study,
we exploit the introduction of air pollution monitors in China to investigate if realtime monitoring of policy outcomes affects enforcement of existing regulations. Using assignment criteria established by the central government and new geo-referenced data on local enforcement activities, we show that monitoring: 1) increases enforcement against local firms, 2) improves the targeting of enforcement, and 3) reduces aggregate pollution. These effects are driven by officials facing performance incentives and are stronger when there is limited scope for data manipulation, suggesting that real-time monitoring improves top-down accountability.<br>

title: Data and Code for: The Impact of Youth Medicaid Eligibility on Adult Incarceration

description: The materials here will replicate all of the tables and figures in "The Impact of Youth Medicaid Eligibility on Adult Incarceration" (Arenberg, Neller, and Stripling, 2022).<br><br>This paper identifies an important spillover associated with public health insurance: reduced incarceration. In 1990, Congress passed legislation that increased Medicaid eligibility for individuals born after September 30, 1983. We show that Black children born just after the cutoff are 5 percent less likely to be incarcerated by age 28, driven primarily by a decrease in incarcerations connected to financially motivated offenses. Children of other races, who experienced almost no gain in Medicaid coverage as a result of the policy, demonstrate no such decline. We find that reduced incarceration in adulthood substantially offsets the initial costs of expanding eligibility.

title: Lake Sediment Pollen and Charcoal from Doe Pond in Westfield MA from 13684 BP to Present

description: Aim
 We analyzed a dataset composed of multiple palaeoclimate and lake-sediment pollen and charcoal records from New England to explore how postglacial changes in forest composition and spatial patterns of vegetation and fire were controlled by regional-scale climate change, a subregional environmental gradient, and landscape-scale variations in soil characteristics.
 
 
 Location
 The 120,000-km2 study area includes parts of Vermont and New Hampshire in the north, where sites are 150-200 km from the Atlantic Ocean, and spans the coastline from southeastern New York to Cape Cod and the adjacent islands, including Block Island, the Elizabeth Islands, Nantucket, and Martha’s Vineyard.
 
 
 Results
 Boreal forest featuring Picea and Pinus banksiana was present across the region when conditions were cool and dry 14,000-12,000 calibrated 14C yrs before present (ybp). Pinus strobus became regionally dominant as temperatures increased between 12,000 and 10,000 ybp. The composition of forests in inland and coastal areas diverged in response to further warming after 10,000 ybp, when Quercus and Pinus rigida expanded across southern New England, while conditions remained cool enough in inland areas to maintain Pinus strobus. Fire severity was high during 10,000-8000 ybp. Increasing precipitation allowed Tsuga canadensis, Fagus grandifolia, and Betula to replace Pinus strobus in inland areas during 9000-8000 ybp, and also led to the expansion of Carya across the coastal part of the region beginning at 7000-6000 ybp. Abrupt cooling at 5500-5000 ybp caused sharp declines in Tsuga in inland areas and Quercus at some coastal sites, and the populations of those taxa remained low until they recovered around 3000 ybp in response to rising precipitation. Throughout most of the Holocene, sites underlain by sandy glacial deposits were occupied by Pinus rigida and Quercus.
 
 
 Main conclusions
 Postglacial changes in the composition and spatial pattern of New England forests were controlled by long-term trends and abrupt shifts in temperature and precipitation, as well as by the environmental gradient between coastal and inland parts of the region. Substrate and soil moisture shaped landscape-scale variations in forest composition. Climate and fuels largely controlled fire severity in New England during the postglacial interval.

title: Data and Code for: The Marginal Returns to Distance Education: Evidence from Mexico’s Telesecundarias

description: This paper analyzes a large-scale and long-running distance
education program in Mexico. We estimate marginal treatment effects (MTEs) for
learning in math and Spanish in telesecundarias relative to traditional Mexican
secondary schools using an empirical framework that allows for unobserved
sorting on gains. The estimated MTEs reveal that school choice is not random
and that the average student experiences significant improvements in both math
and Spanish after just one year of attendance in telesecundarias. We find that
the existing policy reduces educational inequality, and our policy-relevant
treatment effects show that expanding telesecundarias would yield significant
improvements in academic performance.

title: Data & Code For: Is it Who You Are or What You Get?

description: Is the type of financial support provided to businesses more important than which businesses receive it? Loans and grants can lead to differences in optimal investments and in scope for moral hazard. We randomize 3,293 business-loan applicants into receiving a loan, cash grant, in-kind grant or nothing. All treatments equally increase income, yet there are large differences within a treatment group with impacts concentrated at the top of the distribution. Those who succeed with loans are observationally equivalent to those who succeed with grants, showcasing that owner heterogeneity is more important than the type of support received in microenterprise development.

title: Code for: Increasing the Cost of Informal Workers: Evidence from Mexico

description: We estimate the effect of increasing the cost of informal jobs on formal firms’ and workers’ outcomes. We combine administrative records and household surveys, and exploit exogenous variation in the cost of informality generated by over 480,000 random work- site inspections in Mexico. For informal workers, inspections temporarily increase the probability of being formalized at the inspected firm, but separations also rise. For formal workers, we find temporary increases in the probability of remaining formally employed at the inspected firm and in monthly wages. At the firm level, increasing the cost of informal jobs leads to persistently lower formal employment.

title: Data and Code for: Employer Concentration and Wages for Specialized Workers

description: This paper studies how
wages respond to a sudden change in employer concentration by using the
deregulation of the Swedish pharmacy industry. The reform involved a
substantial and policy driven increase in the number of employers that varied
by local labor market. Exploiting this variation, elasticities of wages with
respect to labor market concentration are estimated to be between -0.025 and
-0.061. The positive wage effects from reduced employer concentration are most
prevalent for more mobile workers, as well as younger and foreign born workers.
Overall, the paper finds that employer concentration matters for wages in a
context where skills are industry-specific.

title: Time resolved fullfield imaging of ferroelectric domains of KxNa1-xNbO3 thin films

description: This proposal is a continuation of HC-4354. We study the dynamics of phase transitions, in particular the transition from the ferroelectric monoclinic (Mc-) phase to the ferroelectric orthorhombic (c-) phase in Potassium Sodium Niobate K0.7Na0.3NbO3.
Instead of performing scanning imaging diffraction experiments as in previous beamtimes we plan to resort to time-resolved fullfield imaging. We expect a reduction of the measurement time from 10 hours per delay point to only 20 minutes.
