Behavioral Science Interventions Could Increase Snap Comprehension And Awareness Among Military Families, Colleen Heflin, Hannah Patnaik, Leonard M. Lopoo, Siobhan O'Keefe Nov 2023

Behavioral Science Interventions Could Increase Snap Comprehension And Awareness Among Military Families, Colleen Heflin, Hannah Patnaik, Leonard M. Lopoo, Siobhan O'Keefe

Population Health Research Brief Series

Food insecurity is more common among military families than the general population, and the transition from active service to civilian life is a time of heightened risk. The Supplemental Nutritional Assistance Program (SNAP) is designed to support food security among low-income families. Many eligible military and veteran families do not enroll in SNAP due to a lack of information, stigma, and administrative barriers. This brief highlights findings from a survey experiment conducted in 2022 and 2023 to assess how small changes to SNAP informational flyers, such as simplifying information provided about SNAP, highlighting that other veterans use SNAP, and emphasizing …


Book Review: Kings, Conquerors, Psychopaths: From Alexander To Hitler To The Corporation, Tim Bakken Nov 2023

Book Review: Kings, Conquerors, Psychopaths: From Alexander To Hitler To The Corporation, Tim Bakken

Genocide Studies and Prevention: An International Journal

The book Kings, Conquerors, Psychopaths is a survey of a vast amount of human wrongdoing. It lays bare the motivations of aggressors who wish to subjugate nations or groups of people and corporate executives and government bureaucrats who make discretionary decisions that harm people. Along with cataloging mass killings by despots and soldiers, the book includes stories about Ponzi-schemers and the deaths of automobile drivers and passengers who were killed by vehicle defects known to the manufacturer. The book posits that “[p]owerful, elite forces are trying to force us backward toward a non-democratic state, one where power, wealth, and prerogative …


An Economic Evaluation Of The Use Of Non-Combusted Alternatives Using A Cost Of Illness Approach: The Philippine Case, Christopher James R. Cabuay Nov 2023

An Economic Evaluation Of The Use Of Non-Combusted Alternatives Using A Cost Of Illness Approach: The Philippine Case, Christopher James R. Cabuay

Angelo King Institute for Economic and Business Studies (AKI)

Smoking continues to be one of the leading causes of death and disability around the world. Recent health studies, however, have reported that these diseases are more likely to be due to the smoke from burning rather than the actual nicotine content. This study uses a cost of illness approach in estimating the cost of smoking-related illness in the Philippines and calculating the potential reduction in costs if a significant portion of the adult smoking population switches to the exclusive use of non-combusted alternatives (NCAs), which drastically reduces the risk of contracting smoking-related diseases. This study finds that cost reductions …

Will The Philippine Development Plan 2023-2028 Targets Be Met?, Jesus Felipe

Angelo King Institute for Economic and Business Studies (AKI)

EARLY THIS YEAR, President Ferdinand Marcos, Jr. signed the Philippine Development Plan 2023-2028 (PDP). The document contains hundreds of targets. Some of the key targets to be attained by 2028 are as follows (in fact, the Plan provides yearly targets):

1.) an annual growth rate of 6.5-8% (since 2024); 2.) a gross national income per capita of $6,044-$6,571 (50% higher than that in 2023); 3.) inflation between 2%-4% (from 2.5%-4.5% in 2023); 4.) a government fiscal deficit of 3% (from 6.1% in 2023); 5.) a debt-to-GDP ratio of 48%-53% (from 60%-62% in 2023); 6.) an unemployment rate of 4%-5% (from …


A Brief Comparison Of Two Early Neighborhoods: Consumerism And Social Class In 20th Century Lincoln, Nebraska, Mariska Molnar Nov 2023

How Tiktok “Locks In” Its Users With Reference To What Happened In The Homeland Version Douyin Application, Yang Yang, Li Zi'ang, Zhigen Zhao, Sabrina (Zi Tong) Peng, Liyu Dou, Changyu Li, Yinqi Wang Nov 2023

How Tiktok “Locks In” Its Users With Reference To What Happened In The Homeland Version Douyin Application, Yang Yang, Li Zi'ang, Zhigen Zhao, Sabrina (Zi Tong) Peng, Liyu Dou, Changyu Li, Yinqi Wang

Research Collection School Of Economics

In October 2022, Douyin, the homeland version of TikTok, introduced a new rule requiring all its users to promote only Douyin-approved products during their live-streaming events and in their non-live short-videos. This requirement essentially restricts its users to monetize their content strictly through Douyin-approved products, as promoting products has become the most important source of income for Douyin users. This requirement essentially creates a lock-in effect.

The University of Jordan was selected as the research site due to its size and prominence in Jordan. The study sought to explore female participants’ perspectives on the current economic situation in Jordan, migration aspirations, and desired destinations. Interviews were conducted with undergraduate students at the University of Jordan. Of these ten participants, six expressed clear labor migration aspirations, three expressed aspirations to stay, and one expressed ambivalent migration aspirations. Nearly all participants expressed negative views of …


Tackling Misperceptions About Immigrants With Fact-Checking Interventions: A Randomized Survey Experiment, Syngjoo Choi, Chung-Yoon Choi, Kim Oct 2023

Tackling Misperceptions About Immigrants With Fact-Checking Interventions: A Randomized Survey Experiment, Syngjoo Choi, Chung-Yoon Choi, Kim

Research Collection School Of Economics

We conduct a randomized online survey experiment to study the impact of fact-checking offers and financial incentives on misperceptions about immigrants. We find that natives overestimate the number of immigrants and the social and economic costs of immigration. Offering a free check of the factual information about immigrants reduces these misperceptions; it becomes more effective when combined with financial incentives. However, more than half of the participants never took up offers to check factual information. Using a model of information search with limited attention, we identify the presence of non-negligible costs of information search and processing, which limits the effectiveness …

Economics Faculty Articles and Research

The MECHANISMS study investigates how social norms for adolescent smoking and vaping are transmitted through school friendship networks, and is the first study to use behavioral economics methodology to assess smoking-related social norms. Here, we investigate the effects of selection homophily (the tendency to form friendships with similar peers) and peer influence (a social process whereby an individual’s behavior or attitudes are affected by peers acting as reference points for the individual) on experimentally measured smoking and vaping norms, and other smoking outcomes, in adolescents from high and middle-income settings. Full school year groups in six secondary schools in Northern …


Why The Public Discourse On Education Is Wrong, Jesus Felipe Sep 2023

Why The Public Discourse On Education Is Wrong, Jesus Felipe

Angelo King Institute for Economic and Business Studies (AKI)

ONCE upon a time, the Philippines was praised for its relatively well-educated labor force. Not anymore. The situation seems to have reversed: policymakers and commentators single out education as one of the primary causes for the country’s poor performance (lack of competitiveness) and the unemployability of many of its workers.

To put the discussion in the correct context, I will start by arguing that the relevant measure of progress for a developing nation like the Philippines is productivity. Without productivity increases, there cannot be increases in income. Productivity in the Philippines is low in general. Is education the key to …


Are There Differences In Household Borrowing Across Religions?, Seth Dunn Aug 2023

Are There Differences In Household Borrowing Across Religions?, Seth Dunn

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This study explores the relationship between religion and economic behavior, specifically asking whether variations in household borrowing can be attributable to identification with different Christian religious traditions across the United States. The hypothesis of different borrowing behaviors across religions is motivated historically and theoretically. Historical data from l967 and 1971 are used in ordinary least squared and logistic regression analyses. Density of religious affiliations and relevant controls are used to predict households’ debt and attitudes towards different reasons for borrowing. Some differences across religions are found. This research contributes to a broader literature exploring the impact of religion on economic …


Understanding Factors Influencing Electric Vehicle Adoption: Evidence From Panel Data Analysis, Ryker Brian Aug 2023

Understanding Factors Influencing Electric Vehicle Adoption: Evidence From Panel Data Analysis, Ryker Brian

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This paper investigates the factors influencing the adoption of electric vehicles (EVs) using panel data from California. The analysis employs a panel data model with within effects to examine the relationship between EV adoption rates and various socio-economic factors. The continued analysis gives out-of-sample forecasted results for the 4 counties with the highest share of electric vehicles registered in 2021. Additionally, the paper explores the influence of supply-side issues and complementary infrastructure on EV adoption. An introduction to Hidden Markov Methods is then given as the next step in the research.


Assessing Determinants Of Participation In Conservation Programs In The U. S., Manita Ale Aug 2023

Assessing Determinants Of Participation In Conservation Programs In The U. S., Manita Ale

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The United States Department of Agriculture (USDA) has implemented conservation programs through Natural Resources Conservation Service (NRCS) and Farm Service Agency (FSA). Conservation Reserve Program (CRP), Conservation Stewardship Program (CSP), and Environmental Quality Incentives Program (EQIP) are some of them. These programs provide financial and technical assistance to farmers and ranchers to adopt land management practices that generate environmental benefits. In this study, we explore the determinants of participation in conservation programs (CRP, CSP, EQIP) in Iowa, Kansas, and Nebraska. For this, we use a unique survey-based data set comprising observations from row crop farmers in these states. We are …


Does Fertility Matter For Middle Aged And Older Adults’ Risk Attitudes?, Christine Ho, Bussarawan Teerawichitchainan, Joanne Tan, Eugene Rui Le Tan Aug 2023

Does Fertility Matter For Middle Aged And Older Adults’ Risk Attitudes?, Christine Ho, Bussarawan Teerawichitchainan, Joanne Tan, Eugene Rui Le Tan

Research Collection School Of Economics

Given that risk attitudes influence many decisions, it is important to understand the factors that shape such attitudes in late adulthood, when individuals face important risky decisions. While research finds that parenthood tends to correlate with lower risk tolerance in western countries, there is a lacuna on whether such associations persist in late adulthood, and are applicable to the Asian context, where children are conventionally considered a linchpin of old age support. Data for middle aged and older individuals come from the nationwide Singapore Life Panel (N = 6,740). Multivariate statistical analyses are employed to estimate the associations between willingness …


Beef And Dairy Substitution Effects Associated With Carbon Labeling And An Information Intervention, Sara Gardner Hedgecock Aug 2023

Beef And Dairy Substitution Effects Associated With Carbon Labeling And An Information Intervention, Sara Gardner Hedgecock

Graduate Theses and Dissertations

Understanding consumer perceptions of carbon emissions in agriculture is a critical step to help increase the sustainability of food consumption. According to the Food and Agriculture Organization of the United Nations, 14.5 percent of all global anthropogenic GHG emissions are estimated to be represented by livestock (FAO), and cattle, raised for beef and milk, are the largest animal species responsible for emissions, comprising over 60 percent of the livestock sector’s emissions. This motivates this study’s analysis of beef and dairy milk products and alternatives. To better understand how consumers may substitute meat and milk products when provided with information about …


Monetary Policy And Stagflation: A Trade-Off Between Price Stability And Economic Growth?, Leef H. Dierks Jul 2023

Monetary Policy And Stagflation: A Trade-Off Between Price Stability And Economic Growth?, Leef H. Dierks

Journal of New Finance

Several euro area economies are likely to experience a stagflation in 2023. This situation is characterized by a combination of economic stagnation, i.e., GDP growth falling below its potential growth rate, and a pronounced increase in inflation as was last observed during the 1970s’ oil crisis. A stagflation presents the European Central Bank with a dilemma. Should it further tighten its monetary policy in an attempt to align euro area inflation (expectations) with its target of two per cent p.a. in the medium term? Or should the ECB re-adopt a more accommodative stance so as to stimulate economic growth in …


Search Models Of Money: Alternative Means-Of Payment And Consumer Behaviour With Credit, Kheng Tat Marcus Tan Jul 2023

Search Models Of Money: Alternative Means-Of Payment And Consumer Behaviour With Credit, Kheng Tat Marcus Tan

Dissertations and Theses Collection (Open Access)

This dissertation consists of three chapters on Search Models of Money.

The first chapter is a review of recent advances in Search Models of Money. It reviews the Lagos and Wright (2005) framework which is the workhorse of many modern search models with applications to models with Competing Media of Exchange to Fiat Currency, and models with Money and Credit. We trace the history of the development of search models of money from the first generation to present day. We highlight recent developments that address puzzles such as the coexistence of money in an environment where an asset serves as …


Monitoring The Philippine Economy State Of The Economy Report, Mitzie Irene P. Conchada, Lawrence B. Dacuycuy, Jesus Felipe, Desher Edgar Empeño, Brendan Emmanuel A. Miranda Jul 2023

Monitoring The Philippine Economy State Of The Economy Report, Mitzie Irene P. Conchada, Lawrence B. Dacuycuy, Jesus Felipe, Desher Edgar Empeño, Brendan Emmanuel A. Miranda

Angelo King Institute for Economic and Business Studies (AKI)

The Philippine economy recovered from the COVID-19 pandemic during 2022. It posted a very high annual growth rate, 7.6%, although this must be understood in the context of a low base. AKI’s State of the Economy Report focuses on three issues in the context of the new Administration’s 8-Point Socioeconomic Agenda and the Philippine Development Plan 2023-2028: growth, inflation, and the fiscal deficit and national debt. Overall, we have a positive view of the economy over the medium and long-term. However, we argue that:


-The focus of economic policy has to shift decisively toward changing the structure of the economy …


Reflections On Inflation: How Bad Has It Been?, Jesus Felipe Jul 2023

Reflections On Inflation: How Bad Has It Been?, Jesus Felipe

Angelo King Institute for Economic and Business Studies (AKI)

THE increase in prices that countries have experienced since March 2022 has brought old fears about the deleterious impact of inflation. It is true that prices increased after the Russian invasion of Ukraine and this affected a series of commodities that are imported. Yet, it is important to understand how much prices have increased, the nature of inflation we have experienced, and the reaction of central banks.


The Impact Of Upzoning On Housing Construction In Auckland*, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips Jul 2023

The Impact Of Upzoning On Housing Construction In Auckland*, Ryan Greenaway-Mcgrevy, Peter C. B. Phillips

Research Collection School Of Economics

There is a growing debate about whether upzoning is an effective policy response to housing shortages and unaffordable housing. This paper provides empirical evidence to further inform debate by examining the various impacts of recently implemented zoning reforms on housing construction in Auckland, the largest metropolitan area in New Zealand. In 2016, the city upzoned approximately three quarters of its residential land to facilitate construction of more intensive housing. We use a quasi-experimental approach to analyze the short-run impacts of the reform on construction, allowing for potential shifts in construction from non-upzoned to upzoned areas (displacement effects) that would, if …


The Importance Of The First Generic Substitution: Evidence From Sweden, Aljoscha Janssen, David Granlund Jul 2023

The Importance Of The First Generic Substitution: Evidence From Sweden, Aljoscha Janssen, David Granlund

Research Collection School Of Economics

We analyze changes in the willingness to substitute from prescribed pharmaceuticals to more affordable generic equivalents in response to the first experience with a substitution. Using Swedish individual-level data of prescribed and dispensed pharmaceuticals, we em-ploy a dynamic event study and an instrumental variable approach to show that an initial substitution reduces the probability of opposing subsequent substitutions by 39 percent-age points. We recommend that policy-makers target patients with a history of opposed substitution and offer additional discounts to promote substitution as long-term savings outweigh one-time costs.


Revisiting Development Discourse Amidst Informal Sector Crises Covid-19 Pandemic, Anjan Chakrabarti, Pooja Sharma Jun 2023

Revisiting Development Discourse Amidst Informal Sector Crises Covid-19 Pandemic, Anjan Chakrabarti, Pooja Sharma

International Journal on Responsibility

Amid the COVID-19 pandemic, India has experienced a severe catastrophe of the informal sector, related to both health and livelihood. The informal sector and migrant workers are closely linked and they became easy prey during the nationwide lockdown at the onset of the COVID-19 pandemic. The informal sector, primarily a fallout of the prevailing dual economy, makes it highly imperative to revisit not only India’s growth and development process but also the distribution. The paper attempts to evaluate the development process adopted by developing countries and their relevance in terms of growth and inequality. The study finds the missing link …


The Economic Value Of Sea Otters And Recreational Tourism In A California Estuary, Jessica A. Fujii, Charles S. Colgan, Anthony Castelletto, Michelle M. Staedler, Amy G. Wolfrum, Kyle S. Van Houtan Jun 2023

The Economic Value Of Sea Otters And Recreational Tourism In A California Estuary, Jessica A. Fujii, Charles S. Colgan, Anthony Castelletto, Michelle M. Staedler, Amy G. Wolfrum, Kyle S. Van Houtan

Journal of Ocean and Coastal Economics

The recovery of marine megafauna can lead to improved ecosystem function and services, but not all stakeholders may benefit equally. Quantifying the local economic value of a species’ presence may appeal to broader range of stakeholders when developing conservation strategies. This study aims to examine the economic effect recreational activities can have on a local region, and to determine what role the presence of southern sea otters (Enhydra lutris nereis) had on the value visitors placed on the visit and the area’s preservation. We surveyed visitors to Elkhorn Slough, a small estuary in California known for diverse wildlife, …

Optimal Contest Design When Policing Damaging Behavior, Scott M. Gilpatric, Ye Hong Jun 2023

Optimal Contest Design When Policing Damaging Behavior, Scott M. Gilpatric, Ye Hong

Economics Faculty Publications and Presentations

Abstract

We consider the design of a contest in which the prize may motivate not only productive efforts, but also some damaging aggressive behavior by contestants. The organizer must choose prizes and an enforcement regime defined as a limit on how much aggressiveness will be tolerated and the probability of inspection. When the value of contestants’ output is low, it may be optimal to motivate much less effort than first best because the prize spread necessary to induce higher effort necessitates a high level of enforcement, which is not worth the cost. On the other hand, when the output value …


Fiscal Decentralization And Economic Performance In Selected Developing Federal Econom, Samuel Onyeka Okonkwo, Walter Okwudili Ugwuoke Phd Jun 2023

Fiscal Decentralization And Economic Performance In Selected Developing Federal Econom, Samuel Onyeka Okonkwo, Walter Okwudili Ugwuoke Phd

Bullion

Extant literatures on fiscal decentralization in most developing countries show more concerns on revenue allocation principle/sharing. Contrary to extant studies, this paper undertakes analysis of fiscal decentralization and economic performance in five emerging federal economies. The curiosity is to ascertain if poor economic performance in most emerging economies could be attributed to ill - structured fiscal decentralization. This objective was addressed using Panel Vector Autoregressive technique and impulse response function. The results showed that all the measures of fiscal decentralization such as revenue measure denoted as (FDC1), spending measure denoted as (FDC2) and revenue — spending measure or Simultaneity measure …

Four significant areas will be examined to trace this trajectory. Firstly, the paper examines the effects of calligraphy/typography on Lloyd J. Reynolds. Secondly, it delves into Steve Jobs’ …


Dynamic Effect Of Exchange Rate Gap Shocks On Stock Market Deepening: Evidence From Nigeria, Kareem Abidemi Arikewuyo Jun 2023

Dynamic Effect Of Exchange Rate Gap Shocks On Stock Market Deepening: Evidence From Nigeria, Kareem Abidemi Arikewuyo

CBN Journal of Applied Statistics (JAS)

The study examines the exchange rate gap shock–stock market deepening nexus in Nigeria using the structural VAR-X (SVAR-X) technique for the period 1986Q1 to 2018Q4. Findings reveal that exchange rate gap shock has a negative but statistically not significant effect on stock market deepening in Nigeria. It was also found that exchange rate passed–through interest rate from second to thirteen quarter, and further through financial openness whose effect, like exchange rate gap, was negative. This implies that exchange rate gap is significantly and negatively related to interest rate and financial openness in Nigeria. It is therefore recommended that the monetary …


Modelling The Impact Of Government Expenditure On Economic Growth In Nigeria: The Moderating Effects Of Oil And Non-Oil Revenue, Victor U. Ijirshar, Gaius M. Asombo, Florence D. Bundepuun, Ashifa Tersugh, Ayila Ngutsav Jun 2023

Modelling The Impact Of Government Expenditure On Economic Growth In Nigeria: The Moderating Effects Of Oil And Non-Oil Revenue, Victor U. Ijirshar, Gaius M. Asombo, Florence D. Bundepuun, Ashifa Tersugh, Ayila Ngutsav

CBN Journal of Applied Statistics (JAS)

This study examines the relationship between government expenditure and economic growth and assesses the moderating effects of oil revenue and non-oil revenue in Nigeria from 1981 to 2021. The study uncovered short-term asymmetry in the government expenditure-economic growth nexus while the long-term relationship was symmetric. The study found that government expenditure is a significant determinant of economic growth in Nigeria and that oil and non-oil revenue influences the nexus between government expenditure and economic growth in Nigeria positively. The study recommends efficient management of oil revenue, directing investments during high revenue periods and ensuring fiscal sustainability. Government should also establish …


Improving The Efficiency Of Exponential Ratio-Type Estimator For Population Median: A Calibration Weight Adjustment Approach, Mathew J. Iseh, Kufre J. Bassey Jun 2023

Improving The Efficiency Of Exponential Ratio-Type Estimator For Population Median: A Calibration Weight Adjustment Approach, Mathew J. Iseh, Kufre J. Bassey

CBN Journal of Applied Statistics (JAS)

This paper modifies the Bahl and Tuteja exponential ratio-type estimator for population median under simple random and stratified sampling schemes using calibration weight adjustment technique with supplementary information to vary the stratum weights. The bias and mean square error of the modified estimator were obtained up to the second-order approximation, which satisfies the necessary conditions for efficiency. The findings show that the new estimator surpasses existing estimators in efficiency gain. This suggests the appropriateness of calibration weight modification in boosting the efficiency of a population parameter estimator under stratified random sampling especially where the population parameter of the auxiliary variable …
