The Impact Of State Insulin Copayment Caps On Diabetics In The United States, Ryan C. Meyer
All Theses
Insulin is a life-saving medication for people with diabetes that helps regulate blood glucose levels throughout the body. A Type 1 diabetic cannot survive without insulin, and a Type 2 diabetic’s quality of life greatly diminishes without access and use of this drug. Currently, many diabetics skip, ration, or abstain from insulin due to financial barriers. As of June 2026, 29 states have enacted insulin copayment caps for state-regulated commercial health insurance plans to reduce the financial burden of insulin costs. This study examines the impact of these caps on all commercially insured diabetics in the United States, particularly on …
Semiparametric Cointegrating Rank Selection For Curved Cross-Section Time Series,

Semiparametric Cointegrating Rank Selection For Curved Cross-Section Time Series, Peter C. B. Phillips
Research Collection School Of Economics
Cointegrating rank selection is studied in a function space reduced rank regression where the data are time series of cross-section curves. Consistent cointegrating rank estimation is developed using information criteria extended to curve time series environments. The asymptotic theory involves two-parameter Gaussian processes that generalise the standard limit processes involved in cointegrating regressions. Simulations provide evidence of the effectiveness of consistent rank selection by the BIC criterion and the tendency of AIC to overestimate order as in standard lag order selection in autoregression, as well as in reduced rank regression with multiple time series.

Generosity After Negative Random Shocks, Hernán Bejarano, Joris Gillet, Ismael Rodriguez-Lara
ESI Working Papers
We report the results of three preregistered experiments examining the effects of negative random endowment shocks on generosity. Using a dictator game, we show that generosity is greater towards those who experience a negative random shock, and this effect is larger than the effect inequality has on giving. Our data provide evidence that people do not expect this additional level of generosity after a shock and that injunctive norms cannot explain it either. Taken together, our findings suggest that the (high) level of generosity observed after negative random shocks is unexpected and exceeds what people consider to be socially appropriate. …
Identity-Dependent Externalities Can Mitigate Overbidding In Tullock Contests: Theory And Evidence,

Identity-Dependent Externalities Can Mitigate Overbidding In Tullock Contests: Theory And Evidence, Dan Kovenock, Jian Song, Francesco Trevisan
ESI Working Papers
We investigate how identity-dependent externalities infuence bidding behavior in Tullock lottery contests. While experimental studies of standard contests, in which losers are indiferent to the winner’s identity, consistently document overbidding, the role of identity-dependent preferences remains less explored. We address this gap by frst showing that the class of three-player Tullock lottery contests with identity-dependent externalities considered here can be mapped into a standard Tullock lottery contest with appropriately chosen prize valuations and endowments, yielding identical Nash equilibrium predictions. We then use this mapping to design a laboratory experiment that directly compares the two “equilibrium-equivalent” contest formats. In our three-player …

Jurnal Ekonomi dan Pembangunan Indonesia
Digitalization has become a key pillar in driving economic, social, and governance transformation in Indonesia. However, it is necessary to verify whether digitalization has supported sustainable development goals. This study evaluates the impact of digitalization on sustainability dimensions at the district/city level in Indonesia using the Propensity Score Matching (PSM). The results show that digitalization has a significant negative impact on environmental quality. Conversely, the impact on the economy and social welfare is not statistically significant, indicating that the benefits of digitalization are not evenly distributed and tend to be concentrated among groups that already have digital access and capabilities.

Indonesia’s economic challenges are characterized by stagnant economic growth and regional development disparities. This study analyzes the achievement and convergence of infrastructure development across provinces in Indonesia during 2011–2021 through the construction of an Infrastructure Development Index (IPI). The study employs panel data from 33 provinces, using factor analysis to construct the IPI and the First Difference Generalized Method of Moments (FD-GMM) to examine convergence and its determinants. The results show that many provinces still have IDI scores below the national average. Furthermore, the FD-GMM model shows that σ-convergence and β-convergence occur in Indonesia. In addition, GRDP per capita, inflation, …

This study examines determinants of village economic independence (PADes) in Indonesia, focusing on infrastructure, social capital, and leadership. Using 2024 PODES census data (N=84,240) and clustered logistic regression, results show road infrastructure as the strongest factor (OR: 2.27). A “leadership paradox” emerges, where higher education of village heads negatively correlates with PADes formation. Geographic analysis reveals infrastructure effectiveness depends on topography, with lowland areas gaining the greatest structural advantage. Findings highlight the need for topography-based policy differentiation to strengthen fiscal independence in rural Indonesia.

Conflict-Mediated Group Size Regulation: A Theory Of Supraoptimal And Suboptimal Group Size, Eric Schniter
ESI Working Papers
Observed group sizes rarely match the size that would maximize what each member gets from belonging. We propose a two-part theory in which group size is regulated by two related conflicts: insider-outsider conflict over admission, and within-group conflict as crowding, competition, and social tensions intensify with size. Three strategies are available: admission, exclusion, and fission. The first part shows that even when exclusion is unavailable, fission dynamics alone drive group size away from the optimum in both directions, with the pattern set by how prospective joiners encounter groups and by the geometry of fission. When joiners compare groups across a …

Firm Level Labour Productivity Drivers And Export Status In Tanzania, Mgeni E. Msafiri, Vincent Leyaro, Rosemary Taylor
Tanzanian Economic Review
This study analysed the drivers of firm-level labour productivity by export status and estimated the counterfactual gains from exporting. Using the 2022 nationally representative Tanzania Enterprise Survey and an endogenous switching regression model, results revealed significant differences in the drivers of labour productivity between exporting and non-exporting firms. The productivity of exporting firms was positively associated with business linkages with small and medium-sized enterprises, foreign ownership, access to finance, and capital intensity. Similar factors were associated with labour productivity among non-exporting firms, alongside linkages with large firms. However, access to finance had asymmetric patterns: exporting firms benefited from greater financial …

Bulletin of Monetary Economics and Banking
This study analyzes the Exchange Rate Pass-Through (ERPT) on export and import prices in Indonesia’s manufacturing trade with ASEAN Plus-three countries (China, Japan, and South Korea) using monthly data from 2016 to 2022. Employing the Nonlinear (NARDL) models, we examine the degree and asymmetry of ERPT across five key manufacturing sectors for each partner. The NARDL model confirms asymmetric price responses to currency appreciation and depreciation in several sectors. The findings reveal significant sectoral and country-specific variations. Some export sectors experience complete pass-through in the short term but shift to negative complete passthrough in the long run. Meanwhile, imports from …

Hierarchical Bayesian Evidence On Cbdc Adoption: The Case Of Indonesia’S Digital Rupiah, Akbar Syahid Rabbani, Jongsu Lee
Bulletin of Monetary Economics and Banking
This study analyzed accessibility, privacy, transferability, and interest rates related to the adoption of Digital Rupiah, Indonesia’s Central Bank Digital Currency (CBDC), among rural and urban consumers. Findings from a hierarchical Bayesian model show that mobile applications are the main acquisition channel, and enhanced transferability with bank accounts and electronic money boosts consumer utility. However, there are concerns about fully anonymous transactions, differentiated by socio-demographic profiles (age, income, education, and knowledge). Scenario analysis suggests the potential CBDC adoption rate in Indonesia could range from 38% to 55%, influenced by privacy levels and the central bank’s interest rates.

Is Fdi A Panacea? Unveiling Spillover Effects On Efficiency And Risk In Indonesian Manufacturing, Fichrie Fachrowi Adli, Dyah Wulan Sari, Dian Enggar Lintang Pertiwi, Mohammad Zeqi Yasin
Bulletin of Monetary Economics and Banking
This study builds on Javorcik (2004), who argues that countries attract Foreign Direct Investment (FDI) with the expectation that spillovers will benefit local firms. However, empirical evidence on this effect remains inconsistent. This research addresses the gap by examining the impact of horizontal spillovers not only on production efficiency but also on production risk. It also accounts for firm heterogeneity in the manufacturing sector by classifying technological intensity using unsupervised machine learning, specifically K-means clustering, into three categories based on OECD (2011): High Technology (HT), Medium Technology (MT), and Low Technology (LT). The study uses data from Statistik Industri (SI) …

Parental Gender Bias In Youth Employment Standards: Evidence From Upper Egypt, Mahmoud Saeed
Theses and Dissertations
Youth unemployment remains a critical challenge in Egypt, with female labor force participation among the lowest globally. While structural factors such as limited job creation and public sector contraction are well-documented, the role of family-level decision-making in constraining women's labor market entry has received limited quantitative attention. This thesis examines parental gender bias in employment standards in Upper Egypt, investigating whether and how parents impose systematically different job requirements for daughters compared to sons. Using primary survey data from 17,284 unemployed youth aged 18-35 across six governorates, paired with responses from their parents, this study analyzes parental preferences across six …

Testing Potential Correlations Between Childhood Lead Exposure And Authoritarianism In Adulthood, Kragen Anderson
University Honors Theses
A significant body of research links lead exposure during childhood to negative effects ranging from increased impulsivity to societal level effects such as an increased likelihood of committing violent crime in adulthood. Due to exposure vectors such as lead water pipes, lead solder, lead based paints, and leaded gasoline there was significant lead exposure during childhood for large portions of the American population. This paper tested and found a statistically significant association between average population level lead exposure in childhood and likelihood of voting for candidate Trump later in life.

The Dictatorial Public Goods Game, Gabriele Camera, Gary Charness, Nir Chemeya, Ro'i Zultan
ESI Working Papers
We propose a novel game, the Dictatorial Public Goods Game, to study the interplay between collective resource generation and centralized provision of public goods. After making choices in a standard Voluntary Contribution Mechanism (VCM), one player is selected from the group to administrate the contributions: either provide the public good or expropriate the collected resources for personal gain. We find that adding this centralized mechanism reduces efficiency compared to the standard VCM. Although higher contributions increase the material incentive to expropriate, they lead to more provision. Thus, pro-social choices in the contribution and in the provision stages act as …

Beyond The Shelf: How Reallocating Shelf Space To Emerging Brands Enhances Store Performance Through Dynamic Brand-Level Effects, Jesse Core, Ho Kim
Journal of Applied Marketing Theory
This study examines the effects of reallocating shelf space from established to emerging brands in the flavored malt beverage category, a fast-moving, impulse-driven product category. Using a 13-week field experiment in 16 U.S. grocery stores (six treated, ten control), we reallocated one shelf facing from an established to an emerging brand for four weeks before reverting the shelves to their original configuration. Then we analyzed weekly SKU-level data on sales with fixed-effects panel regressions. Results show that the shelf-space reallocation increased category sales by 21.2% during treatment and 27.6% after reversion, revealing persistent gains. At the brand level, emerging brands …
