The Law Of General Average, Luca Anderlini, Joshua C. Teitelbaum

Georgetown Law Faculty Publications and Other Works

Part of a ship's cargo is jettisoned in order to save the vessel and the remaining cargo from imminent peril. How should the loss be shared among the cargo owners? The law of general average, an ancient principle of maritime law, prescribes that the owners share the loss proportionally according to the respective values of their cargo. We analyze whether the law of general average is a truthful and efficient mechanism. That is, we investigate whether it induces truthful reporting of cargo values and yields a Pareto efficient allocation in equilibrium. We show that the law of general average is …

A Robust Optimization Approach To Mechanism Design, Jiangtao Li, Kexin Wang

Research Collection School Of Economics

We study the design of mechanisms when the mechanism designer faces local uncertainty about agents’ beliefs. Specifically, we consider a designer who does not know the exact beliefs of the agents but is confident that her estimate is within ϵ of the beliefs held by the agents (where ϵ reflects the degree of local uncertainty). Adopting the robust optimization approach, we design mechanisms that incentivize agents to truthfully report their payoff-relevant information regardless of their actual beliefs. For any fixed ϵ, we identify necessary and sufficient conditions under which requiring this sense of robustness is without loss of revenue for …

The Effect Of Crime On Tourism In Indonesia, Muhammad Farhan, Hera Susanti

Journal of Strategic and Global Studies

Tourism sector is widely known as one of economic sectors that can be the engine of economic growth in an effort to reduce poverty in a country. However, growth in the tourism sector can be influenced by safety factors. Tourists tend to avoid tourism destination areas with high crime rates in order to avoid becoming victims of crime. This study aims to analyze the effect of crime on the number of tourist arrivals in Indonesia by using four proxies of crime, which are total crime rate, property crime rate, violent crime rate, and fraud crime rate. This study utilizes a …

Cross-Cultural Interactions And Equilibrium Selection In Stag Hunt Games, Gabriele Camera, James Gilmore, Marilyn Giselle Hazlett, Jason Shachat, Bochen Zhu

ESI Working Papers

We study within-and cross-culture interaction in a Stag Hunt game, using a controlled online experiment with participants from a Chinese and a U.S. university. We investigate if cross-culture interactions support less coordination on the riskier but Pareto efficient Nash equilibrium. Our study mimics the experimental design of previous studies testing this hypothesis, but includes participants from two geographically-separated universities instead of subgroups within a single western university thus providing a stronger delineation between two cultures. Counter to previous studies, we find that cross-culture interactions can have a positive impact on efficiency. Participants from the U.S. university, particularly females, more frequently …

The Examination Of The Mathematical Calculation On Premium Reserve Modifications For Endowment-Life Insurance Products, Farisa Salwa Fatimah, Debrina Ferezagia, Wira Darmiza

Jurnal Administrasi Bisnis Terapan

Insurance offers numerous advantages in managing the diverse dangers it encounters. The level of compensation provided is contingent upon the magnitude of the premium remitted. A fraction of the premium collected by the company must be allocated as a premium reserve to ensure that the company will not have any challenges in settling future claims. The calculation of premium reserves is performed through the utilization of prospective and retrospective reserve methods, which rely on net premiums as the foundation for the computation. The premium reserve calculation approach employs both the Canadian and Full Preliminary Term methodologies. The objective of this …

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.

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 …

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 …

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 …

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 …
