title: Mirror-based perception: are male drivers accurately estimating the distance and speed of motorized two-wheelers?

description: Improving safety during interactions between motorized two-wheelers (MTWs) and cars is one of the critical aspects for enhancing the road traffic environment. As reported, the most frequent MTW crashes occur when cars pull out in front of an oncoming MTW, often due to conspicuity issues and driver perception errors. While existing studies have focused on perceptual error estimation from pedestrians’ and drivers’ perspective using static visual images and short video clips, the current instrumented vehicle-based study attempts to examine drivers’ perceptions in estimating distance (<i>Experiment 1</i>) and speed (<i>Experiment 2</i>) of an approaching MTW while checking side- view mirrors in dynamic traffic environments. A total of 28 licensed professional car drivers of varying ages were considered for this study. For data collection a camera was mounted on the MTW; and two cameras, a VBOX data logger with GPS, were installed in the car. The glance duration data were collected using driver-facing camera. Additionally, non-parametric test methods were adopted to analyze the mirror effect on drivers’ perception. The results of the study indicate that drivers generally tend to overestimate distances while underestimating speeds of motorcycles. Both the distance and speed estimation accuracy decrease with increasing driving speed as well as the longitudinal gap between the vehicles. The perception errors are observed to be more significantly noticeable at higher speeds exceeding 40 kmph or when the MTW is in the farthest distance category. Interestingly, our study also indicates that shorter mirror glance duration may contribute to these higher perception errors. The results were consistent for both the side-view mirrors, although the errors were more pronounced in the passenger’s side mirror, highlighting the possible impact of longer eye-to-mirror distance. Due to perception errors, MTW riders often think that they had ample time and space for maneuvers, leading to risky decision-making and increasing potential collisions. Our findings emphasize the effect of mirror usage in decision-making tasks while driving, underscoring the necessity for enhanced driver training programs and redesigned mirror curvature to make a safer road environment.

title: An analysis of drug recognition expert evaluations and comparisons with police issued citations in Maryland, 2017–2021

description: Drug Recognition Expert (DRE) officers utilize standardized evaluations to assess physiological and behavioral indicators of drug impairment. This study analyzed data from Maryland DRE officers (2017–2021), comparing their drug category/ies assessments with blood tests results. DRE evaluation records were linked to citations issued for alcohol/drug-impaired driving, to examine the agreement between charges, DRE evaluation, arrest outcomes, and repeat offenses. Data from 4,931 DRE evaluations were analyzed, involving 4,727 drivers linked to citation records for alcohol/drug-impaired driving offenses. Agreement between DRE opinions and blood test results was quantified by estimating binomial success probabilities with 95% confidence intervals. Citation outcomes and repeat offense rates for DRE and non-DRE cases were also presented. Of 4,931 unique evaluations, blood specimens were collected in 2,118 (42.9%), yielding 1,599 positive drug test results (75.5%). Most evaluated drivers were white (67.6%), male (73.8%), and aged 21–34 years (43.2%). Comparison of DRE opinion with blood test results revealed an overall success probability of 84.2 ± 0.65%. DRE accuracy improved to 91.8 ± 0.85% when none or one drug was detected and decreased to 80.5 ± 0.87% when two or more drugs were involved. When linked to citation data, 3,237 drivers (68.5%) received 36,878 citations, with 88.1% having two or more drug-related offenses and 72.5% having at least one negligent driving offense. Matched DRE drivers were involved in 9,105 traffic stops, with approximately 48.4% receiving over five citations during their first stop. 97.3% were cited for drug impairment, with only 87 drivers avoiding such citations. This study highlights the effectiveness of the DRE program in identifying impaired drivers, providing insights into driver demographics and impairment patterns, while emphasizing need for improved polysubstance impairment data collection. A high degree of agreement between DRE opinions and blood test results for all tested drug categories were statistically established. Despite the program’s success, significant gaps remain in testing methods and integrating alcohol and drug evaluations. Future research should enhance testing protocols, expanding data collection, and examining the link between substance use disorders and impaired driving to strengthen prevention, enforcement, and intervention efforts.

title: Evaluating risk factors associated with fatalities among powered two-wheeler crashes in the United States

description: The objectives of this study are to: (1) evaluate the fatality risk of powered two-wheeler (PTW) riders in collisions with various types of opponent vehicles; (2) estimate the likelihood of different impact orientations between PTWs and other vehicles involved, and (3) develop an initial crash-based speed–fatality prediction model specific to the United States that controls for vehicle orientation. Data was extracted from the National Highway Traffic Safety Administration’s Crash Reporting Sampling System and the Fatality Analysis Reporting System covering 2017–2021. This data was used to estimate the fatality risks associated with various types of opponent vehicles involved in PTW crashes. The vehicles involved in each crash were coupled based on the vehicles’ impact locations, and the effects of different vehicle orientations on fatality were estimated using odds ratio analysis. Multivariate logistic regressions were used to model the relationship between impact speed and fatality risk for front-end collisions involving PTWs. Crashes involving buses and heavy trucks posed a significantly higher risk to PTW riders, with the fatality risk being four times greater compared to collisions with passenger vehicles. This risk varied based on impact orientation; frontal collisions with the front or sides of the opposing vehicle were the most dangerous, with fatality odds approximately four times higher than rear-end impacts. The speed-fatality prediction model showed the fatality risk increased with higher PTW travel speed while accounting for the expected higher fatality risk in crashes involving older riders, heavy vehicles, or un-helmeted riders. The significant influence of opponent vehicle type on fatality risk in crashes involving PTWs highlights the need for further investigation into vehicle-specific crash prevention and mitigation strategies, especially for light and heavy trucks. Similarly, the high variability in fatality odds across different crash configurations underscores the importance of integrating impact orientation surrogate variables into injury prediction models. The speed–fatality prediction model developed in this study provides a foundational framework for evaluating the effectiveness of advanced rider assistance systems and other safety interventions that reduce crash speed. Future research should explore the benefits of such measures through simulation and real-world testing.

title: Code for "Insufficient or Excessive Investment Under Sovereign Default Risk" JIE 2026

description: Replication package for "Insufficient or Excessive Investment Under Sovereign Default Risk",
Conditionally accepted at the Journal of International Economics

Abstract: Private agents do not internalize the impact of their investment decisions on the sovereign’s bond prices and default risk. Therefore, a standard externality argument implies that investment is insufficient and that a subsidy can improve welfare, if financed by non-distortionary means. We contrast this logic with a countervailing force. When the sovereign is impatient relative to households, plausibly due to political economy factors, it finds laissez-faire capital accumulation excessive and might prefer instead to tax it. We embed both mechanisms in a sovereign default model with decentralized capital investment, long-term public debt, and stochastic trend growth, calibrated to salient features of the Spanish economy. We find that the impatience channel dominates quantitatively, to such an extent that laissez-faire is preferable to the government’s ideal fiscal policy, based on households’ welfare.

title: Eco-Morphological Exploration of Avian Communities and Floral Diversity: Bird-Tree Interactions at Waghai (Dang) Forest, South Gujarat, India

description: The tropical deciduous forests of the Dang district in South Gujarat represent one of the most biodiverse regions in Western India. This study was conducted to document the avifaunal diversity and analyze how tree species composition, phenology, and structural complexity influence bird community dynamics. The primary objective was to quantify species richness and abundance while mapping the ecological niches occupied by different bird guilds in relation to specific tree species. Data were collected using point counts and opportunistic observations. For every bird sighting, the following parameters were recorded: species identity (Order, Family, Common Name), number of individuals, activity (e.g., feeding, calling, perching), and detailed substrate information (tree species name, GBH, tree height, and phenology). Canopy positioning was further categorized into vertical (Lower, Middle, Upper) and horizontal (Inner, Outer) strata to understand microhabitat preferences. A total of 1,003 individuals were recorded, representing 68 bird species belonging to 39 families and 16 orders. The study revealed a highly diverse community with a Shannon-Wiener Diversity Index (H') of 3.60, indicating a well-distributed and ecologically stable population. The Order Passeriformes was the most dominant, with the family Leiothrichidae (e.g., Jungle Babblers) showing the highest abundance. Other significant families included Columbidae (Pigeons and Doves) and Estrildidae (Munias). The analysis of feeding guilds showed a predominance of Insectivorous and Granivorous birds. A critical finding was the strong association between bird presence and specific tree species. Acacia nilotica, Tectona grandis, and Ficus species emerged as vital substrates for perching and feeding activities. Phenological data indicated that trees in the Fruiting and Flowering stages attracted significantly higher bird counts, particularly nectarivorous species like the Purple Sunbird (Cinnyris asiaticus) and frugivores. Birds utilized different canopy layers based on their feeding habits. Insectivores were predominantly found in the middle and upper canopies, while granivores were often associated with the lower canopy or ground level. The "Inner" canopy was frequently used for perching and nesting, providing protection, whereas the "Outer" canopy was the primary site for active feeding and calling. The high species richness and diversity index underscore the conservation importance of the Waghai forest region. The significant correlation between tree phenology and bird activity suggests that maintaining a diverse tree species composition is essential for sustaining the avifaunal community. These findings provide a baseline for future conservation efforts and habitat management in the Dang district, highlighting the need to protect old-growth trees and diverse floral species to maintain ecological balance.
