Building Bridges: Industrial Trade Unions In A Changing Climate, Nicole Möller Dec 2025

Building Bridges: Industrial Trade Unions In A Changing Climate, Nicole Möller

Dissertations - ALL

This dissertation examines how German industrial trade unions and workers in the automobile and coal industries navigate the profound challenges of the green transition. Workers’ experiences are situated within a broader political-economic context shaped partly by market-led decarbonization efforts, welfare retrenchment/austerity, erosion of progressive institutions in society, and global competition, as well as a global restructuring of value accumulation. The analysis critically engages with unions’ current responses to a market-led transition and their implications for labor’s future. The dissertation develops its argument across three empirical chapters. Chapter 2 investigates workplace-level changes in coal mining and automobile production, analyzing how workers …

On Detecting Change-Points Of A Segmented Logistic Regression Model, Jingwen Li Dec 2025

On Detecting Change-Points Of A Segmented Logistic Regression Model, Jingwen Li

Dissertations - ALL

This dissertation investigates the problem of change-point detection in segmented logistic regression models, where the total number of change-points is unknown. We consider both unconstrained models, which allow discontinuities at change-points, and constrained models, which impose continuity across change-points. The central challenge is to determine the number of change-points and to accurately estimate their locations, while ensuring valid statistical inference for the associated regression coefficients. We begin by introducing a set of regularity assumptions that underlie the theoretical analysis throughout this work. For a given number of change-points, we present algorithms to estimate their locations and obtain the maximum likelihood …


Three Essays On The Supplemental Nutrition Assistance Program (Snap): Examining External Shocks, Protective Effects, And Administrative Challenges, Hyojeong Kim Dec 2025

Three Essays On The Supplemental Nutrition Assistance Program (Snap): Examining External Shocks, Protective Effects, And Administrative Challenges, Hyojeong Kim

Dissertations - ALL

Abstract In this dissertation, I present three studies that examine how different forms of inconsistency—arising from timing disruptions, eligibility structures, and administrative churn—shape the functioning and effectiveness of the Supplemental Nutrition Assistance Program (SNAP). Although SNAP is designed to provide a reliable source of food assistance, access to benefits is not always predictable, continuous, or evenly accessible. The studies show that inconsistencies can emerge through external shocks that alter the timing of benefit delivery, through eligibility rules tied to disability determinations in other programs that may exclude self-reported disabled households from accommodations, and through administrative procedures that generate temporary interruptions …

Do Digital Transformation And Macroeconomic Stability Matter For The Asean's Economic Growth?, Sri Andaiyani, Abdul Bashir, Ichsan Hamidi

Bulletin of Monetary Economics and Banking

This work assesses the association between digital transformation, macroeconomic stability, and economic growth. We employ yearly data from 2010 to 2021 in ASEAN countries. The findings show digital transformation and macroeconomic stability can increase in GDP in the long term. Digital transformation contributes favorably and substantially, while macroeconomic stability negatively and significantly affects economic growth in the short-term. The study reveals causal link between digital transformation and macroeconomic stability, causality from digital transformation to economic growth, and economic growth to macroeconomic stability. This implies that digital transformation is the engine of growth.
