The Impact of Unemployment, Inflation, and the Exchange Rate on Economic Growth in South Africa (1994–2022)

International Studies of Economics, EarlyView.
ABSTRACT South Africa's macroeconomic environment continues to be shaped by persistent structural imbalances, including high unemployment, inflationary pressures, and exchange rate fluctuations, all of which have important implications for the country's long‐term economic performance.

Deniers and Compliers: Unpacking the Heterogeneous Effectiveness of U.S. Stay‐at‐Home Mandates During the COVID‐19 Pandemic

Journal of Applied Econometrics, EarlyView.
ABSTRACT While existing work shows COVID‐19 stay‐at‐home (SAH) policies decreased mobility on average, we lack evidence regarding heterogeneity in policy effectiveness across US counties. To uncover potential heterogeneity, we implement a novel two‐stage approach.

Agent‐based versus correlative models of species distributions: Evaluation of predictive performance with real and simulated data

Methods in Ecology and Evolution
Species distribution models (SDMs) have been widely used in ecology to understand how species relate to environmental variation. Most SDMs are correlative, and they lack explicit reference to the underlying processes, and therefore, the reliability of ...

Using Distribution Regression Difference‐in‐Differences to Evaluate the Effects of a Minimum Wage Introduction on the Distributions of Wages, Earnings, and Working Hours

Journal of Applied Econometrics, EarlyView.
ABSTRACT We estimate the causal effects of the introduction of the minimum wage in Germany on the distributions of hourly wages, monthly earnings, and hours worked, combining rich large‐scale data sources. We compare linear and non‐linear versions of distribution regression difference‐in‐differences (DR‐DiD) and also estimate bivariate DR‐DiD.

Economies of Scale to Consumption in Collective Households

Journal of Applied Econometrics, EarlyView.
ABSTRACT Browning et al. (2013) model collective‐household economies of scale in goods consumption by having each good be partly shared, instead of each good being public or private. We modify their model to achieve simple point identification and estimation of the economies of scale of consumption of each good, and we provide a new index of household ...

School Starting Age and the Gender Pay Gap Over the Life Cycle

Journal of Applied Econometrics, EarlyView.
ABSTRACT This paper replicates and extends the evidence on the lifetime effects of school starting age on earnings by Fredriksson and Öckert (2014) for Sweden. Using German data for individuals born between 1945 and 1965, we examine a more rigid system of ability tracking in secondary education, a potential driver of long‐term effects.

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Guidelines for Meta‐Analytic Structural Equation Modeling: Steps, Resources, and Illustrations

Psychology &Marketing, EarlyView.
ABSTRACT The goal of science is to build incremental, structured, and reliable knowledge over time. Yet, many strands of marketing and related disciplines exhibit symptoms of cumulative stagnation, including lack of replicability and weak theoretical integration. Existing remedies such as replication studies, multistudy investigations, and open science

Optimal Experimental Design for Fast and Accurate Relaxation Time Measurements in Magnetic Resonance

Magnetic Resonance in Chemistry, EarlyView.
We apply D‐optimal experimental design to relaxation constant estimation in NMR relaxometry. The resulting sampling schedules concentrate measurements where the signal is most sensitive to the relaxation constant. Compared with conventional linear or logarithmic spacing, D‐optimal designs achieve better estimation accuracy and precision with fewer ...
