title: Effect of metalloproteinase inhibitors and volatilization temperature on the bond strength, nanoleakage, and collagenolytic activity of adhesive restorations

description: Even with the advance of dental materials and techniques, adhesive restorations have long term limitations. The aim in this study was to evaluate the effect of dentin pretreatment with metalloproteinase inhibitors (chlorhexidine 2% - CHX and glutaraldehyde 5% - GD) and the volatilization temperature (23 and 40ºC) of the solvent of the adhesive system on bond strength (BS), nanoleakage (NL), and collagenolytic activity (CA) of adhesive restorations after 24 h and aging. Thirty-six sound human third molars (n = 6) were collected (CAAE 73605617.4.0000.5515), the teeth had coronary dentin of medium depth exposed, then the acid conditioning was performed, followed by dentin pretreatment with distilled water (control), CHX (Clorhexedina, Villevie) or GD (Gluma, Heraeus Kulzer). In the end, the adhesive system was applied by total acid etching technique, volatilized at 23 or 40ºC, and light cured to posterior confection of a composite resin block. The specimens were cut in 0.8 x 0.8 mm sticks, half of the sticks were evaluated after 24 h and the other half was evaluated after aging (10,000 thermal cycles and 4 weeks of storage in 0.2% collagenase). BS was obtained by the microtensile test using a universal test machine and NL will be analyzed by scanning electron microscopy after infiltration with silver nitrate (n = 6). CA was evaluated by in situ zymography using a confocal laser scanning microscopy. Data were analyzed by tree-way ANOVA for repeated measures and Bonferroni test (a = 0.05). Dentin pretreatment using GD showed higher BS (55.03 ± 7.19 MPa) compared to distilled water (49.18 ± 7.23 MPa), and CHX pretreatment showed intermediate BS value (51.89 ± 6.70 MPa). Volatilization of adhesive at 40ºC increased BS (53.32 ±7.23 MPa) compared to 23ºC (50.46 ± 7.27 MPa) and reduced the NI. After thermal cycling and collagenase storage the BS was reduced (50.23 ± 7.72 MPa) compared to 24 h (54.04 ± 6.62 MPa) and CA increased for all groups, especially for pretreatment with water and volatilized at 23ºC. Aging decreased the BS, but dentin pretreatment using GD and the use of warm air stream for solvent volatilization were effective for improvement of BS and to reduce NL and CA of dental adhesive restorations.

title: Data and Code for: Communication Infrastructure and Stabilizing Food Prices: Evidence from the Telegraph Network in China

description: This paper exploits a unique historical setting — the expansion of the telegraph network in the 19th century China when railroads were limited — to examine whether the reduction of information frictions stabilizes grain prices. Employing a difference-in-differences strategy, we find that the telegraph access: 1) reduced both the magnitude and the incidence of extreme prices; 2) mitigated price responses to local weather shocks, but increased the responsiveness to shocks in other telegraph-connected regions; 3) affected the price volatility in a mean-reverting pattern, i.e. volatility rose in previously price-stable regions and volatility decreased in price-unstable regions.

title: Data and Code for: Hometown Favoritism and the Quality of Government Monitoring: Evidence from Rotation of Chinese Auditors

description: Audits are a standard mechanism for reducing corruption in government investments. The quality of audits themselves, however, may be affected by relationships between auditor and target. We study whether provincial chief auditors in China show greater leniency in evaluating prefecture governments in their hometowns. In city-fixed-effect specifications - in which the role of shared background is identified from auditor turnover - we show that hometown auditors find 38 percent less in questionable monies. This hometown effect is similar throughout the auditor's tenure, and is diminished for audits ordered by the provincial Organizations Department as a result of the departure of top city officials. We argue that our findings are most readily explained by leniency toward local officials rather than an endogenous response to concerns of better enforcement by hometown auditors. We complement these city-level findings with firm-level analyses of earnings manipulation by state-owned enterprises via real activity manipulation (a standard measure from the accounting literature), which we show is higher under hometown auditors.

title: Data and code for: Credit Rationing and Pass-Through in Supply Chains: Theory and Evidence from Bangladesh

description: Traders are often blamed for high prices, prompting government regulation. We study the effects of a government ban of a layer of financing intermediaries in Bangladesh's edible oil supply chain during 2011-12. Contrary to the predictions of a standard model of an oligopolistic supply chain, the ban caused downstream wholesale and retail prices to rise, and pass-through of imported crude oil price changes to fall. These results can be explained by an extension of the standard model to incorporate trade credit frictions, where intermediaries expand credit access of downstream traders.<br>

title: Data and Code for: Migration Networks and Location Decisions: Evidence from U.S. Mass Migration

description: This paper studies how birth town migration networks affected long-run location decisions during historical U.S. migration episodes. We develop a new method to estimate the strength of migration networks for each receiving and sending location. Our estimates imply that when one randomly chosen African American moved from a Southern birth town to a destination county, then 1.9 additional black migrants made the same move on average. For white migrants from the Great Plains, the average is only 0.4. Networks were particularly important in connecting black migrants with attractive employment opportunities and played a larger role in less costly moves.

title: Data and Code for "Minority Salience and Political Extremism"

description: We investigate how the salience of an ethnic minority affects the majority group's voting behavior. We use the increased salience of Muslim communities during Ramadan as a natural experiment. Exploiting exogenous variation in the distance of election dates to Ramadan over the 1980 2013 period in Germany, our findings reveal an increased polarization. Vote shares for both right- and left-wing extremist parties increase in municipalities with mosques when an election takes place shortly after Ramadan. We use survey data to provide evidence on mechanisms: Ramadan increases respondents' perceived share of the foreign-born population and emphasizes cultural dissimilarities, ultimately worsening attitudes towards Muslims.

title: Data and Code for: Uber vs. Taxi: A Driver's Eye View

description: Rideshare drivers pay a proportion of their fares to a ride-hailing platform operator, a commission-based compensation model used by many service providers. To Uber drivers, this commission is known as the Uber fee. By contrast, traditional taxi drivers in most US cities make a fixed payment independent of their earnings, usually a weekly or daily medallion lease, keeping every fare dollar net of lease costs and other expenses. We assess these compensation models using an experiment that offered random samples of Boston Uber drivers opportunities to lease a virtual taxi medallion that eliminates the Uber fee. Some drivers were offered a negative fee. Drivers’ labor supply response to our offers reveals a large intertemporal substitution elasticity, on the order of 1.2, and higher for those who accept lease contracts. At the same time, our virtual lease program was under- subscribed: many drivers who would have benefitted from buying an inexpensive lease chose to sit out. We use these results to compute the average compensation required to make drivers indifferent between rideshare and taxi-style compensation contracts. The results suggest that rideshare drivers gain considerably from the opportunity to drive without leasing.
description: Boston Uber drivers were eligible for inclusion in the experiment if they took at least four trips and drove an average of 5-25 hours per week in the four weeks prior to selection (the last 3 weeks of July and the first week of August 2016). A total of 1600 eligible drivers were selected for inclusion in the experiment. Drivers were selected within strata defined by hours bandwidth (high/low) and 3 groups based on car age and commission (car 2003 or older, newer car & 20% fee, newer car & 25% fee).
description: Uber drivers in Boston who were active on the platform (more than 4 completed trips) in the month leading up to August 16, 2016 and whose weekly hours averaged between 5 and 25 hours/week (excluding 0's) were eligible for the experiment. We randomly selected 1600 of these drivers for inclusion in the experiment. Only data for these drivers was used in the paper.

title: Soil Respiration Along a Hydrological Gradient at Harvard Forest EMS Tower 2003-2006

description: Soil respiration is an important component of the terrestrial carbon budget. Spatial variation of organic matter and plant cover induce temperature and moisture gradations that obscure direct response of soil respiration to radiative forcing. Separation of spatial patterns from microclimate and substrate availability is vital to predict the response to global change. We are measuring temporal and spatial patterns of soil CO2 flux across a hydrological gradient from wetland to upland soils. A system of 8 automated opaque chambers were installed in 2003 along a hydrological gradient on the northeast margin of the "Beaver Swamp" north of the EMS tower (+42.537755,-72.171478). Two additional clear chambers were installed in the wetland in 2006. Each automated chamber closes for a measurement every four hours. The resulting semi-continuous data has been providing a high-temporal density characterization of soil flux during the growing season since 2003. Soil temperature and moisture were recorded in the litter, organic, and mineral soils during 2004 at three locations along the slope. These structures will provide a database of soil respiration flux, temperature, and soil moisture with both high spatial and temporal resolution, across multiple cover types and ground water levels. The analysis will seek to determine the appropriate spatial scale of soil respiration measurement in eastern hardwood forests.

title: Data and Code for: Maternal Depression, Women's Empowerment, and Parental Investment: Evidence from a Randomized Control Trial

description: We evaluate the medium-term impacts of treating maternal depression on women's mental health, financial empowerment, and parenting decisions. We leverage variation induced by a cluster-randomized control trial that provided psychotherapy to 903 prenatally depressed mothers in rural Pakistan. It was one of the world's largest psychotherapy interventions, and it dramatically reduced postpartum depression. Seven years after psychotherapy concluded, we returned to the study site to find that impacts on women's mental health had persisted, with a 17% reduction in depression rates. The intervention also improved women's financial empowerment and increased both time- and money-intensive parental investments by between 0.2 and 0.3 standard deviations.
description: Response Rates: The starting experimental sample consisted of 463 treated and 440 control mothers. At the 7-year follow-up, we located 295 of the control dyads and 289 of the intervention arm dyads, together corresponding to 64.8% of the baseline sample.A third of the attrition was due to child mortality which was not different by treatment status. The non-experimental group interviewed at the 7-year follow-up consisted of 300 mother-child dyads, 150 from each arm.
