The Influence Of System Optimization On Improving The Quality Of Administrative Services In The Ministry Of Education, Culture, Research And Technology, Mohammad Ridha, Dhini Novia Azaria

Jurnal Administrasi Bisnis Terapan

ABSTRACT

Correspondence and record management are crucial components of a company or institute. Although often considered as things that do not require primary attention, these two components can have a very important role in the occurrence of an event. Along with the development of technology, the management of correspondence and archives is also growing. Generally, the development of this management is in the form of the emergence of an application that can accommodate the needs of correspondence and archives of a company or institute. In Ministry of Education, Culture, Research, and Technology, the application is called "Sistem Naskah Dinas Elektronik" …

Rank-Guaranteed Auctions, Wei He, Jiangtao Li, Weijie Zhong

Research Collection School Of Economics

We propose a combinatorial ascending auction that is “approximately” optimal, requiring minimal rationality to achieve this level of optimality, and is robust to strategic and distributional uncertainties. Specifically, the auction is rankguaranteed, meaning that for any menu M and any valuation profile, the ex-post revenue is guaranteed to be at least as high as the highest revenue achievable from feasible allocations, taking the (|M| + 1)th-highest valuation for each bundle as the price. Our analysis highlights a crucial aspect of combinatorial auction design, namely, the design of menus. We provide simple and sufficient menus in various settings.

Two Essays On Asset Prices Around Securities Class Action Lawsuits, Sounak Saha

Theses and Dissertations in Business Administration

Essay 1: Prior studies on securities class action lawsuits have found that there are large negative abnormal returns and an increase in short-selling activity in the days preceding the lawsuit filing. These findings have largely been attributed to anticipatory inference and private information. However, our analysis of a large sample spanning 2009-2019 reveals that more than half of the lawsuits had a public announcement about the law firm investigation in the days leading up to the lawsuit filing. Strikingly, we find that the average cumulative abnormal return during the 10-day pre-filing period was: (1) over -17% for lawsuits with a …

Coarse Revealed Preference, Gaoji Hu, Jiangtao Li, John K-H Quah, Rui Tang

Research Collection School Of Economics

We propose a novel concept of rationalization, called coarse rationalization, tailored for the analysis of datasets where an agent’s choices are imperfectly observed. We characterize those datasets which are rationalizable in this sense and present an efficient algorithm to verify the characterizing condition. We then demonstrate how our results can be applied through a duality approach to test the rationalizability of datasets with perfectly observed choices but imprecisely observed linear budget sets. For datasets that consist of both perfectly observed feasible sets and choices but are inconsistent with perfect rationality, our results could be used to measure the extent to …

The Effect Of The Claim Recovery Process On Claim Payments In Insurance, Aulia Yasmin, Karin Amelia Safitri, Fachri Muslim

Jurnal Administrasi Bisnis Terapan

The policies and tactics used by an insurance company to effectively handle and recover claims are referred to as the claim recovery process policy. Ensuring total operational stability, preserving customer satisfaction, and limiting financial losses all depend on this approach. The recovery process policy is covered in this study along with how it affects how well a corporation manages risk. A review of the literature and interviews with many employees are part of the research methodology. It was discovered that one of the insurance companies in Indonesia still needed to improve (digitize) its current policy regarding the recovery process. This …

Comparison Of Value At Risk Using Historical And Monte Carlo Methods On Pt Xyz Stock Portofolio, Eka Fitriani, Yulial Hikmah, Ira Rosianal Hikmah

Jurnal Administrasi Bisnis Terapan

One way to achieve profits in a company is through investment activities. However, everything has risks. Investing can also be risky. Therefore, the relationship between risk and investment is important because it will influence the determination of investment selection. The problem faced by investors is choosing an efficient portfolio, or a portfolio that provides the smallest risk. This risk can be done by measuring risk, one of which is using the Value at Risk (VaR) measure. Measurement using Value at Risk has several methods that are quite popular, namely the Historical Method, Variance-Covariance, and Monte Carlo. In this research, the …

Who Helps Tsimane Children And Adults?, Eric Schniter, Daniel K. Cummings, Paul L. Hooper, Jonathan Stieglitz, Benjamin C. Trumble, Hillard S. Kaplan, Michael D. Gurven

ESI Working Papers

We examine various forms of helping behavior among Tsimane Amerindians of Bolivia, focusing on the provision of shelter, childcare, food, sickcare, cultural influence, and traditional story knowledge. Kin selection theory traditionally explains nepotistic nurturing of youth by closely related kin. However, less attention has been given to understanding the help provided by individuals without close genetic relatedness. To explain who provides various forms of help, we evaluate support for several predictions derived from kin selection theory. Our results show that helpers who are most often closely related and from an older generation tend to provide more costly forms of help …

Minimum Wage: Theoretical And Empirical Debates, Ghofran Alrebh

Electronic Theses and Dissertations

This thesis aims to explore the evolution of research methodologies in the minimum wage debate, focusing on the contrasting perspectives of the neoclassical and institutional models. By examining the changes in research methodologies employed by economists from these two schools, this study seeks to shed the light on the shifting paradigms and the impact of these changes on our understanding of minimum wage policies and their implications. This highlights the limitations of relying on one economic school of thought in understanding socio-economic phenomena complexations and policy decisions. As well as it creates the necessity to critical evaluation of the method …

Institutional And Structural Evolution Of The U.S. Financial System 1945-2023: The Long-Wave Financial Cycle And The Role Of Thwarting Mechanisms, Shaun K. Brog

Electronic Theses and Dissertations

This thesis develops a theoretical framework that attempts to explain the dynamic interactions that lead to episodes of severe financial instability. Adapting Minsky’s Financial Instability Hypothesis to the specific characteristics of financial intermediaries and building on Ferri and Minsky’s ideas regarding the role of thwarting institutions, I propose that financial fragility is the result of a long-wave cycle in financial relations characterized by significant institutional and structural evolution within the U.S. financial system. This evolution results in a preponderance of financial activity undertaken outside the regulatory umbrella while margins-of-safety are eroded, newly innovated financial assets proliferate, and financial intermediaries become …

Refugees Insertion And Labor Market Outcomes And: An Analysis Of The Egyptian Context, Salma Ebrahim

Theses and Dissertations

This thesis examines the association between the inflow of refugees to Egypt and labor market outcomes during the period 2012-2018, using data from the Egyptian Labor Market Panel Survey (ELMPS). By applying Difference-in Differences and Probit models, the study compares labor market outcomes between Greater Cairo, characterized by high refugee inflow, and the Suez Canal region, which has a very low inflow. The labor force outcomes analyzed wages, formality and labor force participation. The results indicate that the refugee influx is associated with a decline in wages for both formal and informal workers in the treatment group compared to the …

Comedy Tonight? Maximizing Theatre Audiences Using A Game Theory Model, Emma Lavaune Johnson

Quantitative Social Science Undergraduate Senior Theses

Existing theatre industry literature is comprised of several arguments regarding the amount of literature on the theatre industry. Several scholars argue that the theatre industry is not extensively studied in economics due to misconceptions about the profitability of theatre, the misalignment between artists’ actions and economic “rationality,” and the contributions of the arts industries to the broader U.S. economy. Beyond this academic debate, economic research on the theatre industry explores the nuances of theatre demand and the influence of audience preferences and demographics on theatre ticket demand.

This paper presents a game-theoretic model to study the strategic season selection decisions …

We Cannot Labor Our Way Out Of Oppression: An Exploratory Study Of Wealth Through Black Women’S Lived Experience, Tiffany N. Younger

Dissertations, Theses, and Capstone Projects

An exploratory qualitative phenomenological study was used to explore Black women’s experiences with wealth accumulation. The aims of this study were to better understand how Black women navigate financial obligations as heads of households and the impact of the wealth gap on their lives. The research on the wealth gap, informed by U.S. values and culture, has assumed the accumulation of wealth is the baseline/default goal or aspiration for all individuals. More specifically the subaims of this study sought to examine the extent to which the structural, interpersonal, disciplinary, and hegemony impacts Black women’s wealth status. Furthermore, this study sought …

Value Added Tax Rate Variation, Import Demand And Sectoral Output In Nigeria, Joshua K. Nomkuha, Aondoawase Asooso, Philip T. Abachi

CBN Journal of Applied Statistics (JAS)

This study employs computable general equilibrium (CGE) model to estimate the effect of increase in value added tax (VAT), from 5 per cent to 7.5 per cent, on import demand and sectoral output in Nigeria. The study uses 2020 as the base year for the data analysis. The results show that increase in VAT affects import demand negatively, based on import penetration ratios, with mixed effect across six sectors. The implication of the result is that the VAT policy discourage consumption of foreign products, and constitute excess burden to consumers of such products in Nigeria. The results further reveal that …

Trade Liberalization, Non-Oil Export And Economic Growth In Nigeria, Jerome T. Andohol, Terhemen Tarzoor, Dennis T. Nomor

CBN Journal of Applied Statistics (JAS)

The study examines the impact of trade liberalization and non-oil exports on economic growth in Nigeria from 1986 to 2021. The study utilizes an autoregressive distributed lag model and found the combined effect of trade liberalization and non-oil exports to be positive and statistical significant. While trade liberalization alone may have negative consequences, its synergy with a robust non-oil export can drive sustainable economic growth. The study recommends that strategies to enhance non-oil exports should be encouraged to support the effectiveness of trade liberalization in promoting growth.

The Effectiveness Of Monetary Policy Transmission In Nigeria: Evidence From The Monetary Policy Rate And The Cash Reserve Ratio, Abdulrahman A. Nadani, Auwal Isah

CBN Journal of Applied Statistics (JAS)

This paper investigates the effectiveness of the Monetary Policy Rate (MPR) and Cash Reserve Ratio (CRR) as policy instruments in Nigeria. A structural VAR model is employed to simulate two distinct models measuring shocks from the MPR and the CRR using monthly data from January 2006 to December 2023. Findings show that contractionary monetary policy impulses using MPR and the CRR contract output and credit to the private sector, inflation remains largely positive in the two models, known as the “price puzzle”, but the puzzle is more persistent in the MPR equation. Moreover, shock to MPR strongly influences short-term interest …

Stock Market Volatility In The United Kingdom: Simulating Post-Covid-19 Recovery, Bala A. Dahiru, Mohammed Shuaibu, Najibullah Hassanov

CBN Journal of Applied Statistics (JAS)

This paper investigates the time it would take for the FTSE-100 index to reach its post-COVID-19 peak. The paper utilises an exponential generalised autoregressive conditional heteroscedasticity (EGARCH) model that accounts for leverage effect and asymmetries. The preferred models amongst competing variants was the Autoregressive Moving Average (ARMA)-EGARCH(2,1) specification and was used to predict daily FTSE-100 data from 5th January 2000 to 21st June 2024. The empirical exercise showed that the COVID-19-induced financial crisis negatively affected the United Kingdom’s stock market performance. The results show that the FTSE100 index could reach its post-pandemic peak around 27th August, 2024 (two months after …

Impact Of Covid-19 Pandemic On Performance Of Nigerian Stock Market, Shafiu Ibrahim Abdullahi

CBN Journal of Applied Statistics (JAS)

This study analyzes the effect of COVID-19 pandemic on the performance of Nigerian stock market. The study uses a number of models that include autoregressive distributed lag, vector auto regression, exponential generalized autoregressive conditional heteroskedasticity and multivariate generalized autoregressive conditional heteroskedasticity models. Findings show that reported cases of COVID-19 have causal effect on daily returns of the Nigerian stock market. The results also show that Nigerian stocks are good for portfolio diversification. The results of variance decomposition confirm the declining importance of COVID-19 cases and deaths as the pandemic slows down. Further results show that, for the duration of the …

Impact Of Fiscal Policy On Financial Inclusion And Development In Nigeria, Okwanya Innocent, Taiwo A. Olusegun, Aimua E. Peace

CBN Journal of Applied Statistics (JAS)

This paper examines the effect of fiscal policy on financial inclusion and development in Nigeria. The study employs the Autoregressive Distributed Lag (ARDL) model and impulse response function (IRF) to determine the extent and response of financial inclusion and development to fiscal policy changes in Nigeria. The study derives a financial inclusion index from three core indicators: access, usage and quality of financial services, while financial development is measured as the ratio of money supply to GDP (M2/GDP). The results show that government expenditure has a significant positive effect on financial inclusion and development, while tax revenue exerts a negative …

Ideology And Economic Change, Jared Rubin, Debin Ma

ESI Working Papers

This paper revisits the old theses of the contrasting paths to modernization between Japan and China. It develops a new analytical framework regarding the role of ideology and ideological change—Meiji Japan’s decisive turn towards the West pitted against Qing China’s lethargic response to Western imperialism—as the key driver behind these contrasting paths. Our framework and historical narrative highlight the contrast between Tokugawa Japan’s feudal, decentralized political regime and Qing China’s centralized bureaucratic system as a key determinant driving the differential patterns of ideological realignment. We argue that the 1894-95 Japanese naval victory over China could not be justified under the …

Moral Content Diminishes Preference Falsification, Maxine Bonneau, Tanya O'Garra, Praveen Kujal

ESI Working Papers

We examine how the moral (or neutral) content of an issue influences the tendency to falsify attitudes, given varying social and monetary incentives to engage in such ‘preference falsification’. We conduct an incentivized two stage online experimental study where, in a prior first stage, attitude strength over moral and neutral issues is elicited. Then, in the second stage participants in groups of ten were asked to express their preferences regarding the moral or neutral issues for each possible combination of supporters and opposers in their group, each associated with varying monetary payoffs. More than half of the participants falsify their …

Preference Conflict And Peace Studies: The Line Between Disagreement And Violence, Frederic R. Kellogg

Peace and Conflict Studies

Broadening the definition of conflict defines more comprehensively the condition of peace, focusing on how unresolved shared disagreements can lead to, or avoid, polarization and violence. The line between general disagreement and violent conflict lies in the adjustment of shared preferences. Matters like reproductive rights, medically assisted death, race and gender discrimination, while subject to political polarization, are open to peaceful redress through what John Dewey called the transformative continuum of inquiry, in which the crucial social response to shared problems includes dispute and conflict. Resolution of controversial social problems requires preference adjustment and habit change, often, if not always, …

On The Stability Of Norms And Norm-Following Propensity: A Cross-Cultural Panel Study With Adolescents, Erik O. Kimbrough, Erin L. Krupka, Rajnish Kumar, Jennifer M. Murray, Abhijit Ramalingam, Sharon Sánchez‑Franco, Olga L. Sarmiento, Frank Kee, Ruth F. Hunter

Economics Faculty Articles and Research

Norm-based accounts of social behavior in economics typically reflect tradeoffs between maximization of own consumption utility and conformity to social norms. Theories of norm-following tend to assume that there exists a single, stable, commonly known injunctive social norm for a given choice setting and that each person has a stable propensity to follow social norms. We collect panel data on 1468 participants aged 11–15 years in Belfast, Northern Ireland and Bogotá, Colombia in which we measure norms for the dictator game and norm-following propensity twice at 10 weeks apart. We test these basic assumptions and find that norm-following propensity is …

Match Stability With A Costly And Flexible Number Of Positions, James Gilmore

Behavioral and Computational Economics (MS) Theses

One of the objectives of two-sided matching mechanisms is to pair two groups of agents such that there is no incentive for pair deviation. The outcome of a match can significantly impact participants. While much of the existing research in this field addresses the matching with fixed quotas, this is not always applicable. We introduce the concept of slot stability, recognizing the potential motivation for organizations to modify their quotas after the match. We propose an algorithm designed to create stable and slot stable matches by employing flexible, endogenous quotas to address this issue.

The Lottery Colonel Blotto Game With Draws, Jingzhi Liu

Behavioral and Computational Economics (MS) Theses

This study presents a novel exploration of the lottery Colonel Blotto game. This adaptation introduces the possibility of draws or ties, moving beyond the traditional winner-take-all framework. The inclusion of the possibility of a draw allows for a more realistic depiction of contests where players may arbitrarily split the value of a battlefield in the absence of a decisive victory. Our model is characterized by the number of battlefields, battlefield values that may vary across battlefields, but are symmetric across players, the distinct player shares of each battlefield value captured in the event of a draw, the potentially asymmetric budgets …

Economic Anomalies Following The Handover Of Hong Kong, Nathan Martin

Economics Undergraduate Honors Theses

This paper seeks to examine and provide a possible explanation for economic anomalies in Hong Kong following its handover to China. Hong Kong was on a 99-year lease to the United Kingdom from China before being handed back over July 1^st, 1997. Due to the “one country, two systems” policy espoused in the handover agreement that was to be implemented for fifty years, this event marks a rare natural experiment of a peaceful regime change without a significant change in governance. This paper seeks to understand the impact of the act of regime change on selected key macroeconomic …

A Red Awakening: An Analysis Of China’S Quest For Global Dominance Through Economic Alternative Warfare Methods, Sarah Beddingfield

Senior Honors Theses

In the 2023 annual meeting of China’s parliament, Chinese President Xi made it clear to his political leaders and the world that he was preparing for war. This should come as no surprise after analysis of China's grand strategy points clearly to the intent to surpass the U.S. as the premier global superpower in all respects. China has been building towards this goal for years through untraditional methods of warfare, forcing the national security community to reevaluate its own strategy and assess the Chinese threat through a different lens. This thesis seeks to address one specific area in which China …

Industrialized environments, despite benefits such as higher levels of formal education and lower rates of infections, can also have pernicious impacts upon brain atrophy. Partly for this reason, comparing age-related brain volume trajectories between industrialized and non-industrialized populations can help to suggest lifestyle correlates of brain health. The Tsimane, indigenous to the Bolivian Amazon, derive their subsistence from foraging and horticulture and are physically active. The Moseten, a mixed-ethnicity farming population, are physically active but less than the Tsimane. Within both populations (N = 1024; age range = 46–83), we calculated regional brain volumes from computed tomography and compared …

Incorporating Institutions And Ideology: Why Covid Didn't Change Anything, Cullen Kendrick

Departmental Honors & Graduate Capstone Projects

In this paper, I investigate the aftermath of the COVID-19 pandemic through an economic and philosophical lens to try and understand why government aid was removed. Looking at the problem as solely a structural issue, with Jurgen Habermas’ Between Facts and Norms and Douglas North’s Institutions, Institutional Change, and Economic Performance guiding my understanding, provides useful insights. Namely, how the informal and formal structures of society interact, and their cyclical nature. However, that perspective does not provide a complete picture. And so, I developed an understanding of ideology to investigate the origins of informal societal structures. To do this I …

Cooperation In Temporary Partnerships, Gabriele Camera, Alessandro Gioffré

ESI Working Papers

The literature on cooperation in infinitely repeated Prisoner’s Dilemmas covers the extreme opposites of the matching spectrum: partners, a player’s opponent never changes, and strangers, a player’s opponent randomly changes in every period. Here, we extend the analysis to settings where the opponent changes, but not in every period. In these temporary partnerships, players can deter some deviations by directly sanctioning their partner. Hence, relaxing the extreme assumption of one-period matchings can support some cooperation also off equilibrium because a class of strategies emerges that are less extreme than the typical “grim” strategy. We establish conditions supporting full …

Despertando Del Sueño Americano: U.S. Policies Influencing Cartel Profitability From Undocumented Border Crossing, Gisela Martinez Acosta

Undergraduate Theses

Due to U.S. border policies limiting safe and lawful passage, cartels have developed an industry in the U.S.-Mexico border that supplies crossing services to migrants, utilizing coercive means to regulate the market and profiting from migrant’s desperation to enter the country. This study combines economic and ethnographic research to describe the human smuggling industry and the impact it has in the migrant journey. Scarcity, inelastic demand, black markets, and monopolies are economic concepts used to understand the operations of these services. Observational research and interviews conducted in the Sonoran Desert are also included to present this topic humanely. Background on …
