Dampak Jumlah Kredit Yang Dimiliki Rumah Tangga Terhadap Kekerasan Dalam Rumah Tangga (Kdrt) Pada Anak Di Indonesia, Anjar Maulitfiani, Dwini Handayani

Jurnal Kebijakan Ekonomi

This study examines the impact of intensity of household debt on domestic violence (DV) towards children in Indonesia. There is a positive relationship between the amount of household debt and the likelihood of domestic violence towards children based on literature review. This research uses a quantitative method with multinomial logistic regression analysis. The results of this study indicate that households with more than one household debt are correlated with an increased likelihood of both psychological and physical domestic violence towards children compared to the likelihood of no domestic violence, both before and after controlling variables added.

Exploring Successful Financing Strategies For Developing Real Estate In Cameroon, Esoh Etebe Elah

Walden Dissertations and Doctoral Studies

Financing constraints have become a significant problem for leaders of small and medium-sized enterprises (SMEs) developing real estate in Cameroon. Cameroon SME real estate development leaders often lack knowledge of financing strategies to mitigate financial barriers and improve business sustainability. Grounded in the financing constraint theory, this qualitative pragmatic inquiry project was to explore the successful financing strategies Cameroon SME real estate development leaders used. Seven leaders of Cameroon real estate development SMEs were interviewed, and public documents were reviewed. The semistructured interview and document data were analyzed using thematic analysis, resulting in five themes: (a) financing strategies, (b) funding …

Estimation Of Serially Correlated Error Components Models Using Whittle’S Approximate Maximum Likelihood Method, Badi H. Baltagi, Georges Bresson, Jean-Michel Etienne

Center for Policy Research

This chapter studies the estimation of error components models with serial correlation of the 𝐴𝑅𝑀𝐴(𝑝, 𝑞) type using Whittle’s (Whittle, 1953) approximate maximum likelihood method. This is done for the one-way and two-way error components panel data model. Monte Carlo simulations are performed that investigate the small sample performance of this method.

Essays On Operational Issues Of Online Medical Consultation Platforms, Jinxin Zhang

Lingnan Theses (MPhil & PhD)

The increased demand for Online Medical Consultation (OMC) services has accelerated the development of Online Medical Consultation Platforms (OMCPs). OMCPs are third-party digital platforms on which patients can access medical consultation services with comparatively less effort and lower cost, while physicians can expand their service coverage and benefit financially from the provision of paid OMC services in their spare time. Although OMCPs have attracted a growing interest in academia, the role of various decision-making behaviors of physicians on these platforms on their patients and themselves remains unclear. To fill this research gap, we conduct two empirical studies based on proprietary …

Abundance Strategies Should Promote Abundant Jobs In Distressed Places, Timothy J. Bartik

Upjohn Institute Policy Papers

A prominent recent policy debate is about “abundance policies”: policies to make it easier to build housing or infrastructure, deliver government services more quickly and more efficiently, and expedite the public funding of the most innovative and socially impactful research. In this essay, I argue that abundance advocates often mistakenly ignore or have a negative attitude toward “place-based policies.” These place-based policies would seek to increase employment rates, particularly in good jobs, in two types of distressed places that lack abundant job opportunities: distressed local labor markets and distressed neighborhoods. Both the goals and means of place-based policies fit into …

Impacts Of U.S. Environmental Regulations On Industry, Xiao Ji, Mengyu Wang, Tianyi Zhang

Sim Kee Boon Institute for Financial Economics

This paper analyzes the impacts of U.S. environmental regulations on industry, focusing on command-and-control environmental regulations (CCER) and market-based environmental regulations (MBER). Drawing on empirical data from the Environmental Protection Agency (EPA) spanning over four decades, we examine key legislation such as the Clean Water Act (CWA), Clean Air Act (CAA), and the Resource Conservation and Recovery Act (RCRA), while also discussing more recent frameworks like the Inflation Reduction Act (IRA). Our findings suggest that although penalties under CCER contribute to immediate compliance, they often fail to elicit long-term changes in corporate behavior. In contrast, MBER, exemplified by the IRA, …

Nowcasting Disruptions To Human Capital Formation: Evidence From High-Frequency Household And Geospatial Data In Rural Malawi, E. J. Tennant, Aleksandr Michuda, J. B. Upton, A. Chamorro, R. Engstrom, M. L. Mann, D. Newhouse, M. Weber, C. B. Barrett

Economics Faculty Works

Exposure to extreme weather events and other adverse shocks has led to an increasing number of humanitarian crises in developing countries in recent years. These events cause acute suffering and compromise future welfare by adversely impacting human capital formation among vulnerable populations. Early and accurate detection of adverse shocks to food security, health, and schooling is critical to facilitating timely and well-targeted humanitarian interventions to minimize these detrimental effects. Yet monitoring data are rarely available with the frequency and spatial granularity needed. This paper uses high-frequency household survey data from the Rapid Feedback Monitoring System, collected in 2020–23 in southern …

Regulatory Impacts On Us Hazardous Waste Exports, Xiaofan Ji, Mengyu Wang, Tianyi Zhang

Sim Kee Boon Institute for Financial Economics

This paper examines the impact of key domestic and international regulations on US hazardous waste exports, focusing on shifts in export destinations and waste types from 2002 to 2023. Since 2005, OECD countries and US Trade Agreement Partners have become primary destinations for US hazardous waste, with significant surges after 2018 and a notable decline in 2022. An analysis of the regulatory landscape reveals that, while international frameworks such as the Basel Convention of 2021 have had a relatively limited impact on reducing US hazardous waste exports, domestic policies—particularly those in California—have more directly influenced export behaviors. Additionally, the US …

Risk, Uncertainty, World Business Cycles, And The U.S. Stock-Oil Relationship, André Varella Mollick

Economics and Finance Faculty Publications

We examine in this paper the transmission of geopolitical risks (GPR), VIX, economic policy uncertainty (EPU), and “macro uncertainty” shocks to real WTI oil and U.S. stock returns (S&P 500). Structural vector autoregressions (SVAR) are applied to monthly data from 1990:1 to 2023:6 with identification based on long-run restrictions of impulse responses from risk/uncertainty measures to world industrial production. The main results are: First, oil prices respond positively to shocks in GPR and macro uncertainty in the short-run, but not to shocks in VIX and EPU. Second, stock returns respond negatively and for longer to both GPR and VIX shocks. …

Growth With Firm-To-Firm Trade, Samuel Kortum, Bernardo Ribeiro

Cowles Foundation Discussion Papers

We explore how connections between buyers and suppliers of intermediate inputs evolve over time to promote firm growth. To formalize this process we develop a dynamic model of a granular endogenous production network, making stark assumptions that yield a tractable parsimonious framework. In the model, producers gradually build up a network of contacts by meeting other producers and source an intermediate input from their cheapest contact at any moment. They retain full recall, so can always switch to a producer contacted previously, even if they never bought from it before. Through this process the production network itself becomes an endogenous …

Max-Share Misidentification, Liyu Dou, Paul Ho, Thomas Lubik

Research Collection School Of Economics

While max-share identiffcation has become increasingly popular in a wide range of applications, we show that its validity requires necessary and suffffcient conditions that are rarely satisffed in practice—the target variable’s response to the target shock must be (i) orthogonal to its responses to untargeted shocks and (ii) larger than combinations of those responses. Imposing additional restrictions on the target shock weakens but does not fully eliminate these conditions. We show that in practice, the weight max-share places on an identiffed untargeted shock can be obtained by projecting the response to that shock on the max-share response. We also theoretically …

Speculative Bubbles In The Recent Ai Boom: Nasdaq And The Magnificent Seven, Rerotlhe B. Basele, Peter C. B. Phillips, Shuping Shi

Research Collection School Of Economics

The recent artificial intelligence (AI) boom covers a period of rapid innovation and wide adoption of AI intelligence technologies across diverse industries. These developments have fueled an unprecedented frenzy in the Nasdaq, with AI-focused companies experiencing soaring stock prices that raise concerns about speculative bubbles and real-economy consequences. Against this background, this study investigates the formation of speculative bubbles in the Nasdaq stock market with a specific focus on the so-called Magnificent Seven (Mag-7) individual stocks during the AI boom, spanning the period from January 2017 to January 2025. We apply the real-time PSY bubble detection methodology of Phillips et …

Learning Camp, Language Of Instruction, And Education Outcomes: Evidence From A Field Experiment In Malawi, Hyuncheol Bryant. Kim, Kim

Research Collection School Of Economics

We conducted a randomized experiment to study the impacts of a summer learning camp and the language of instruction on education outcomes. The program, covering social studies and mathematics, provided additional high-quality learning time for 4th and 5th graders in Malawi. The program significantly increased test scores in social studies and mathematics (0.24–0.36 standard deviations). We find suggestive evidence that the impact on test scores in social studies was greater for students instructed in Chichewa, the local language, than for those instructed in English. However, we find no such evidence of differential impacts on test scores in mathematics by the …

Policy Evaluation With Nonlinear Trended Outcomes: Covid-19 Vaccination Rates In The United States, Lynn Bergeland Morgan, Peter C. B. Phillips, Donggyu Sul

Research Collection School Of Economics

This paper discusses pitfalls in two way fixed effects (TWFE) regressions when the outcome variables contain nonlinear and possibly stochastic trend components. If a policy change shifts trend paths of outcome variables, TWFE estimation can distort results and invalidate inference, especially in a context of evolving policy decisions. A robust solution is proposed by allowing for dynamic club membership empirically using a relative convergence test procedure. The determinants of respective club memberships are assessed by panel ordered logit regressions. The approach allows for policy evolution and shifts in outcomes according to a convergence cluster framework with transitions over time and …

A General Test For Functional Inequalities, Jia Li, Zhipeng Liao, Wenyu Zhou

Research Collection School Of Economics

This paper develops a nonparametric test for general functional inequalities that include conditional moment inequalities as a special case. It is shown that the test controls size uniformly over a large class of distributions for observed data, importantly allowing for general forms of time series dependence. New results on uniform growing dimensional Gaussian coupling for general mixingale processes are developed for this purpose, which readily accommodate most applications in economics and finance. The proposed method is applied in a portfolio evaluation context to test for “all-weather” portfolios with uniformly superior conditional Sharpe ratio functions.

(Wp 2025-05) Expanding Black Reparations With Human And Social Capital Investments, John B. Davis

Economics Working Papers

Disadvantaged social groups in the US suffered disproportionately in the covid pandemic and Great Recession, worsening high levels of inequality associated with their post-1980 declining intergenerational income mobility. For black Americans this reflects the long history of racial discrimination beginning with slavery. Reparations paid to descendants of enslaved individuals to eliminate the black-white wealth gap is a step toward addressing this history. A further needed step is to build predominantly black communities human and social capital through public investments in community health care centers (CHCs) and historically black colleges and universities (HBCUs). There is considerable evidence that investments in early …

Forgoing Nuclear: Nuclear Power Plant Closures And Carbon Emissions In The United States, Luke Petach

Faculty Scholarship

This paper examines the effect of nuclear power plant decommissioning on electricity generation and carbon emissions in the United States. Using data on nuclear reactor closures in the United States between 1993 and 2022 and data on state-level carbon emissions and electricity generation from the Energy Information Administration (EIA), this paper adopts a difference-in- differences (DiD) approach to estimate the effect of nuclear decommissioning. Two-way fixed-effects (TWFE) DiD estimates suggest a nuclear plant closure increases annual state-level per capita carbon emissions between 6% and 8%. The increase in state-level carbon emissions is driven by a substitution toward fossil fuel electricity—particularly …

Horses And The Transition From Feudalism To Capitalism., Thomas E. Lambert

Faculty and Staff Scholarship

Many scholarly articles and books have been written about the transition from feudalism to capitalism over the decades. The various points of views on what is the “main driver” or “prime mover” of the transition have been debated in various forums by historians and economic historians with a different major factor being advocated by different proponents or schools of thought. This paper tries to offer another analysis of how the horse could have been an important “means to an end” in the development of capitalism, and this analysis possibly can lead to support for more than one view of what …

(When) Can Trade Wars Be Good?, Henry S. Gao, Weihuan Zhou

Research Collection Yong Pung How School Of Law

‘Trade wars are good, and easy to win,’ tweeted Donald Trump in 2018. The US–China trade war that followed proved otherwise – especially when confronting a major economic power. Yet, can trade wars ever be good? While the academic consensus holds they harm all participants, we argue that under certain circumstances they can produce positive outcomes. Set against the backdrop of the Liberation Day tariffs announced on April 2, 2025, this paper examines the limits of the Ricardian free trade model underpinning the current multilateral trading system, identifies when trade wars may serve strategic goals, and explores alternative rules to …

Robust Ai Solutions For Financial Markets Through Generative Modeling, Dynamic Graph Learning, And Reinforcement-Based Portfolio Optimization, Jingyi Gu

Dissertations

Financial markets are inherently uncertain and dynamic, driven by complex factors such as macroeconomic signals, investor sentiment, and evolving inter-asset relationships. While machine learning has advanced financial modeling, existing approaches often fall short in addressing the real-world intricacies of finance. This dissertation confronts two critical challenges, human-driven stochasticity and risk-intensive decision-making under real-world trading constraints, while seizing a pivotal opportunity, the structural dynamics of evolving financial systems. These elements are foundational to advancing robust and practical financial intelligence.

To this end, this dissertation develops a unified framework for robust financial modeling and decision-making. The framework is architected as a progressive, …

The Concept Of Maqāṣid Al-Sharī‘Ah And Maṣlaḥah In The Classical And Contemporary Tafsîr, Yusuf Wibisono, Femmy Roeslan

International Journal of Islamic Economics and Business Sustainability

A contemporary mufassir (Qur’anic exegete) employs the principle of al-‘ibrah bi maqāṣid al-sharī‘ah—that interpretation must refer to the objectives of Islamic law—in an effort to uncover the true meaning of the Qur’anic text. A purely literal reading of the Qur’an, without an understanding of its maqāṣid (objectives), faces many limitations. The maqāṣid approach emphasizes not only the wording of the text but also its underlying purposes and goals. The greatest strength of maqāṣid-based tafsīr (interpretation) lies in its ability to render the Qur’an always relevant, adaptable, and universally applicable. As an interpretive approach not strictly tied to …

Pipeline Vs. Choice: The Global Gender Gap In Stem Applications, Isaac Ahimbisibwe, Adam Altjmed, Georgy Artemov, Andres Barrios-Fernandez, Aspasia Bizopoulou, Martti Kaila, Jin-Tan Liu, Rigissa Megalokonomou, José Montalban, Christopher Neilson, Jintao Sun, Sebastian Otero, Xiaoyang Ye

Cowles Foundation Discussion Papers

Women account for only 35% of global STEM graduates, a share unchanged for a decade. We use administrative microdata from centralized university admissions in ten systems to deliver the first crossnational decomposition of the STEM gender gap into a pipeline gap (academic preparedness) and a choice gap (first-choice field conditional on eligibility). In deferred-acceptance platforms where eligibility is score-based, we isolate preferences from access. The pipeline gap varies widely, from -19 to +31 percentage points across education systems. By contrast, the choice gap is remarkably stable: high-scoring women are 25 percentage points less likely than men to rank STEM first.

Cooling Protocols Impact On Nickel-Titanium Rotary Instruments Cyclic Fatigue Resistance Under Extreme Curvatures And Sodium Hypochlorite, Palak Ravjibhai Ranparia, Chintan Joshi, Mona Somani, Aashray Patel, Urooj Desai, Janki Prajapati

Methods: A 90° curved stainless-steel block was used for cyclic fatigue tests on 60 randomly selected rotary instruments, divided into two groups of 30: body temperature (n = 10) and body temperature with cooling (n = 10). Instruments were further subdivided into 6 groups of 3 different instruments. Cooling protocol group instruments received 5-second spray cooling every 30 seconds, along with continuous 5% …

Neutral Zone Vs. Conventional Denture Fabrication: A Randomized Crossover Study On Denture Performance, Karthik Kannaiyan, Arunima Chauhan, Vijayendranath Nayak, Riyshmaa Devendaran, Dashmita Peterson, Pavittra Kanesan, Vityaa Lakshmi

Journal of Dentistry Indonesia

Objectives: It is challenging to achieve satisfactory outcomes in a complete denture for patients with resorbed residual ridges. Utilization of neutral zone techniques to guide posterior denture tooth arrangement and denture base contouring has been considered for many decades. However, the evidence is still not enough to revise protocols. This study aimed to compare patient satisfaction and stability of neutral zone denture with conventional denture. Methods: A crossover clinical trial was conducted among patients with resorbed mandibular ridges. Each participant received two sets of dentures: one fabricated using the neutral zone technique and one using the conventional method, in a …

Revisiting Kin And Ethnic Favoritism In The Bribery Experiment, Mahsa Akbari, Duman Bahrami-Rad, Erik O. Kimbrough

Economics Faculty Articles and Research

We report a conceptual replication of Akbari et al. (2020), who study the impact of co-ethnicity and kinship on behavior in an experimental “bribery game”. In the game, player A can offer a bribe to B, who can help A by inefficiently transferring resources from passive third-party C. We replicate the finding that by varying the relatedness of A, B and C, we can substantially modulate the willingness of A to offer the bribe and the willingness of B to reciprocate the bribe by harming C. The findings are consistent with theories of kin altruism and ethnic favoritism.

The Cost Of Capital Calculation In The Project Finance Settings, Paweł Mielcarz, Dmytro Osiichuk, Adrian Struciński

Journal of Banking and Financial Economics

The paper aims at elucidating and solving the methodological problems around the estimation of the cost of capital in the project finance settings. By convention, capital budgeting analysts evaluate project finance ventures using the free cash flow for equity (FCFE) method, whereby cash flows, including cash, whose distribution is limited by debt covenants, are discounted with the project’s cost of equity. We argue that this approach is erroneous. From the standpoint of the sponsor company, only distributable cash flows should be taken into consideration when evaluating project finance ventures. In turn, the discount rate should be equal to the weighted …
