Labour Research Conference 2018: Upskilling Of Mature Workers, Stephen Hoskins, Luca Facchinello

Research Collection School Of Economics

Many developed countries are approaching an era of ageing population due to an increase in longevity and decrease in fertility rates. Singapore is no exception, having one of the fastest ageing populations in Asia, which is driven by low fertility rates and the third longest life expectancy in the world. The number of elderly citizens, defined as those aged 65 and above, is expected to triple to 900,000 by 2030, making up about 28% of the total population in Singapore (Population SG, 2016). This changing population age profile, combined with a competitive labour market, means it makes business sense to …

The Impact Of In-House Unnatural Death On Property Values: Evidence From Hong Kong, Zheng Chang, Jing Li

Research Collection School Of Economics

The occurrence of in-house unnatural death could negatively affect the value of housing property. This study evaluates the geographic and temporal scope of the impact of unnatural death on property values in Hong Kong. By exploiting the spatial and intertemporal variation of the shock in a difference-in-differences approach, we find significant negative externalities of unnatural death incidence on neighborhood housing values. On average, units in which an unnatural death occurred experience a 25% drop in value following the death. Nearby units on the same floor also show a significant price drop of 4.5%. Prices of units on other floors of …

On Strategy-Proofness And The Salience Of Single-Peakedness, Shurojit Chatterji, Jordi Masso

Research Collection School Of Economics

We consider strategy-proof social choice functions operating on a rich domain of preference profiles. We show that if the social choice function satisfies in addition tops-onlyness, anonymity and unanimity then the preferences in the domain have to satisfy a variant of single-peakedness (referred to as semilattice single-peakedness). We do so by deriving from the social choice function an endogenous partial order (a semilattice) from which the notion of a semilattice single-peaked preference can be defined. We also provide a converse of this main finding. Finally, we show how well-known restricted domains under which nontrivial strategy-proof social choice functions are admissible …

News Co-Occurrence, Attention Spillover, And Return Predictability, Li Guo, Lin Peng, Yubo Tao, Jun Tu

Research Collection School Of Economics

We examine the effect of investor attention spillover on stock return predictability. Using a novel measure, the News Network Triggered Attention index (NNTA), we find that NNTA negatively predicts market returns with a monthly in(out)-of-sample R-square of 5.97% (5.80%). In the cross-section, a long-short portfolio based on news co-occurrence generates a significant monthly alpha of 68 basis points. The results are robust to the inclusion of alternative attention proxies, sentiment measures, other news- and information-based predictors, across recession and expansion periods. We further validate the attention spillover effect by showing that news co-mentioning leads to greater increases in Google and …

Estimating Switching Costs With Market Share Data: An Application To Medicare Part D, Jung Won Yeo, Daniel P. Miller

Research Collection School Of Economics

Choice inertia and switching frictions are well-documented features of the demand for health insurance. In this paper, we estimate switching costs in the Medicare Part D market with aggregate market share data using standard discrete choice models for differentiated products. We consider various modelling assumptions: myopic and forward-looking consumers, and with and without random coefficients. Both myopic and forward-looking consumer models with no random coefficients yield switching cost estimates that closely match the actual average switching frequency, with implied dollar-valued switching costs of $1600 to $2000. We find the inclusion of random coefficients to the myopic consumer model results in …

On Incentive Compatible, Individually Rational Public Good Provision Mechanisms, Takashi Kunimoto, Cuiling Zhang

Research Collection School Of Economics

This paper characterizes mechanisms satisfying Bayesian incentive compatibility (BIC) and interim individual rationality (IIR) in the classical public good provision problem. Many papers in the literature obtain the results in the so-called standard model of ex ante identical agents with a continuous, closed interval of types. Although the standard model and more generally a continuum type space are widely used in the literature, it is nonetheless an abstraction of reality. Given that the public good provision problem has occupied a central application in the theory of mechanism design, we propose a "stress test" for the results in the standard model …

Specification Tests Based On Mcmc Output, Yong Li, Jun Yu, Tao Zeng

Research Collection School Of Economics

Two test statistics are proposed to determine model specification after a model is estimated by an MCMC method. The first test is the MCMC version of IOSA test and its asymptotic null distribution is normal. The second test is motivated from the power enhancement technique of Fan et al. (2015). It combines a component (J1) that tests a null point hypothesis in an expanded model and a power enhancement component (J0) obtained from the first test. It is shown that J0 converges to zero when the null model is correctly specified and diverges when the null model is misspecified. Also …

Estimation Of Large Dimensional Factor Models With An Unknown Number Of Breaks, Shujie Ma, Liangjun Su

Research Collection School Of Economics

In this paper we study the estimation of a large dimensional factor model when the factor loadingsexhibit an unknown number of changes over time. We propose a novel three-step procedure to detect the breaks if any and then identify their locations. In the first step, we divide the whole time span into subintervals and fit a conventional factor model on each interval. In the second step, we apply the adaptive fused group Lasso to identify intervals containing a break. In the third step, we devise a grid search method to estimate the location of the break on each identified interval. …

Entrepreneurship, College, And Credit: The Golden Triangle, Roberto M. Samaniego, Juliana Yu Sun

Research Collection School Of Economics

We develop a model to evaluate the aggregate impact of college finance in an environment with entrepreneurship. The calibrated model captures the stylized fact that entrepreneurs with college are more common and more profitable in the United States. The calibration indicates this is mainly because higher labor earnings allow college‐educated agents to ameliorate credit constraints if and when they eventually become entrepreneurs. Changes in financing constraints on entrepreneurs can thus affect college attendance, and changes in financing constraints on college can affect entrepreneurship rates as well.

Strategic Sequential Bidding For Government Land Auction Sales – Evidence From Singapore, Sumit Agarwal, Jing Li, Ernie Teo, Alan Cheong

Research Collection School Of Economics

This paper studies the extent to which equilibrium auction prices are pushed up sequentially due to strategic bidding behaviors in government land auction sales. Using a unique dataset that covers the universe of tendering prices submitted by all developers for all residential land auction sales in Singapore, we find that a tenderer’s bids are significantly higher where there was a previous land parcel sold within two years and located within four kilometers. The elevated price margin decreases with time and geographic distance. Tracking sequential bids submitted by same developers over time, we find that the incumbent winner of a previous …

An Examination Of The Stock Market’S Effect On Economic Inequality, Nicholas J. Golina

Undergraduate Economic Review

The literature on economic inequality has shown that stock markets can negatively impact aggregate demand because it indicates a higher concentration of wealth in the hands of the top 10% as opposed to the middle class. The stock market could be one of the factors leading to increased inequality. This study contributes to the literature by analyzing stock markets in OECD countries. Building on Tsountas et al (2015), the results showed that stock markets can have a positive impact on inequality, but with weak economic significance. It is recommended that policymakers should focus on factors that more greatly impact inequality.

Breaking The Poverty Trap In Africa: A Comparative Perspective On Poverty Alleviation, Abu Girma Moges

International Journal of African Development

An increasing number of African countries have recently registered improved rates of economic growth. Translating economic growth into poverty reduction, however, requires putting into place policies and institutions that promote a sustainable and shared economic growth process. The degree of success in poverty reduction depends largely on balancing the process of economic growth and the judicious pattern of income distribution so that an increasing share of the population benefits from the growth process and engages in more productive endeavors. Building the necessary policy and institutional framework to promote sustainable and shared economic growth is central in breaking the poverty trap …

Indigenous Knowledge And The Development Debate In Africa, Fidelis Ewane, Samson Ajagbe

International Journal of African Development

This research employs Bourdieu’s theory of habitus to explain the disposition of the donor community to integrate indigenous knowledge systems and practices into development projects. The theory’s objectivist perspective specifies the mechanism that links structural conditioning to social practice and regularities. It holds that power is culturally and symbolically created, and it is constantly re-legitimized through the interplay of agency and structure. This facilitates an analysis of the development field as social space characterized by indigenous and donor power relations. It argues that the reinforcement of indigenous knowledge as the main channel for development will generate transferable local capacities and …

Does Inclusive Growth Matter For Regional Integration In Africa? An Empirical Assessment, Mohammed Shuaibu, Mamello Nchake

International Journal of African Development

Inclusive growth is an important channel through which African countries can foster higher regional integration especially through trade. This is because many African countries are characterized by exclusive growth, small and fragmented domestic markets that are landlocked and often prone to external shocks. Using an augmented gravity specification, this paper conducts an empirical investigation of the relationship between regional integration and inclusive growth in Africa. The adapted model is estimated using ordinary least squares, Pseudo Poisson maximum likelihood estimator and the Blundell-Bond system generalized method of moment estimator. The empirical results reveal that inclusive growth plays a vital role towards …

The Impact Of Motivation On Employee Performance In Selected Insurance Companies In Nigeria., Oluwayomi A. Ekundayo Mr.

International Journal of African Development

Motivation refers to a complexity of forces that inspires a person at work to intensify his desire and willingness to use his potentialities to perform in order to achieve organizational goals or objectives. This study investigates the relationship between motivation and the level of employee performance as applied to some selected insurance companies in Lagos. The study has three main objectives: to evaluate the effects of motivation on employee performance in some selected insurance companies, to assess motivational factors that can influence employee performance, and to recommend possible policies and innovations for better performance of the employees and increased profitability. …

Sustainable Energy Transitions: Changing The ‘Business As Usual’ Trajectory In Sub-Saharan African Urban Areas, Mark Borchers, Megan Euston-Brown, Simon Bawakyillenuo, Alex Ndibwami, Simon Batchelor

International Journal of African Development

This paper describes a novel approach to helping municipal authorities address the sustainable energy challenges associated with rapidly growing urban populations in Sub-Saharan Africa. Population in Africa is expected to double between 2010 and 2040, and substantial urban growth is expected in small and medium-sized cities where local government capacity constraints are most serious. A long-term partnership between municipal authorities, NGOs, and academics can build capacity, and a prescribed strategy can lead to progress on the ground. In order to contribute to future action, the paper argues for a greater role of local government in sustainable energy transitions, and presents …

The Tigray Identity And The Paradox In The Securitization Of The Oromo And Amhara Identities In Ethiopia, Anwar Hassen Tsega

International Journal of African Development

Tigray’s ethnic nationality is the minority identity in the ruling Ethiopian People’s Revolutionary Democratic Front (EPRDF), a coalition of four political parties under the leadership of the Tigray People’s Liberation Front (TPLF). For decades, the ruling party has governed by pitting the Oromo and Amhara against one another. Accordingly, the Oromo-Amhara solidarity is the greatest threat to the Ethiopian government. Within the framework of the Copenhagen school, we analyzed the securitization of the two majority identities. This essay is split into two sections. The first examines why and how the Oromo and Amhara identities have been securitized by the dominant …

Initiative 427: Nebraska Medicaid Expansion, J. David Aiken

Cornhusker Economics

This article summarizes information regarding Initiative 427–the Medicaid expansion question on the November 6, 2018 ballot. It reprints the actual ballot language and the Nebraska Secretary of State’s summary of arguments for and against Initiative 427.

Background. Originally Medicaid covered the elderly, the disabled, children in low-income families, and low-income pregnant women. In 2010 Medicaid coverage was expanded by Congress to include the working poor. In 2012 the U.S. Supreme Court ruled that the provision of the Affordable Care Act (ACA) requiring states to expand Medicaid was unconstitutional. This made it a state option whether or not to expand Medicaid. …

Are Mexican And U.S. Workers Complements Or Substitutes?, Raymond Robertson

Mission Foods Texas-Mexico Center Research

Fears of NAFTA in the United States were largely based on the belief that Mexicans and U.S. workers were substitutes: lowering barriers would allow competing products into the United States and investment outflows that would cause U.S. workers to lose their jobs to Mexico. While this may have been true when NAFTA first went into effect, subsequent production specialization between Mexico and the United States may suggest that Mexican and U.S. workers are now complements. In particular, NAFTA may have induced production restructuring throughout North America to generate integrated value chains in which workers in the three NAFTA countries work …

Separating Between Unobserved Consumer Types: Evidence From Airlines, Diego Escobari, Manuel A. Hernandez

School of Economics and Finance Faculty Publications

We propose an alternative approach to identify unobserved consumer types and assess whether firms price discriminate. Unlike other screening schemes that rely on quantity discounts or product differentiation, in our finite mixture structure individuals have unit demands and the product is homogeneous. We implement the model using an original U.S. airlines data set. The results support the existence of two demand types. The high-type “business” traveler is less price sensitive, has a higher valuation, and pays a higher price than the low type “tourist.” The proportion of high types also increases as the departure date nears. (JEL C23, L93, …

Impact Of Airplane Crashes On Firm's Credit Risk Under The Creditgrades Model, Alexandros Bougias

Undergraduate Economic Review

The paper examines the impact of airplane accidents with 40 or more fatalities, on airline's firm credit risk. The sample contains 20 airplane crashes for the period 2000-2017. The analysis proposes the CreditGrades model introduced by Finger et al. (2002) , which is an extension of the first passage time model of Black and Cox (1976). The study concludes that airplane accidents lead to a statistically significant increase in airline's Probability of Default. The results are both significant and robust under the t-Test and the non-parametric Wilcoxon Signed-rank test.

Agglomeration And The Extent Of The Market: An Experimental Investigation Into Spatially Coordinated Exchange, Jordan Adamson

ESI Working Papers

How and why do agglomerations emerge? While economic historians emphasize trade and economic geographers emphasize variety, we still don’t understand the role of coordination. I fill this gap by extending the model of Fudenberg and Ellison (2003) to formalize Smith’s (1776) theory of agglomeration. I then test the model in a laboratory experiment and find individuals tend to coalesce purely to coordinate exchange, with more agglomeration when there is a larger variety of goods in the economy. I also find that tying individuals to the land reduces agglomeration, but magnifies the effect of variety.

Modeling The Determinants Of Handle: Standardbred Racing At Woodbine And Mohawk, Steven S. Vickner Ph.D., National Thoroughbred Racing Association

Faculty and Staff Scholarship

Using data for 2,742 races over 241 race days from the 2009 Standardbred racing season at the Woodbine and Mohawk Racetracks, all sources single-leg handle (win, place, show, exacta, trifecta, superfecta) per race was modeled with explanatory variables controlling for field size, field quality and race conditions, and seasonality.

Promise Scholarship Programs And Local Prosperity, Michelle Miller-Adams, Edward Smith

Upjohn Institute Policy Papers

We argue that place-based college scholarships, if designed intentionally and leveraged effectively, can foster local economic development. Since the introduction of the Kalamazoo Promise in 2005, a growing number of communities have applied the place-based approach to investments in human capital through the creation of college scholarship programs. Reviewing the existing literature on educational and economic outcomes associated with Promise programs reveals that they can expand students’ postsecondary aspirations, improve a school district’s college-going culture, and increase college enrollment and degree attainment while promoting in-migration of residents and positive growth in housing prices. Therefore, these programs can serve a broader …

Nebraska Monthly Economic Indicators: October 24, 2018, Eric Thompson

Leading Economic Indicator Reports

The Leading Economic Indicator – Nebraska (LEI-N) 1 fell by 0.35% during September of 2018. The decline in the LEI-N, which is designed to predict economic activity six months into the future, suggests that Nebraska economic growth will slow in the coming months. Initial claims for unemployment insurance rose in Nebraska during September, while building permits for single-family and airline passenger counts both declined. Business expectations were a bright spot for the Nebraska economy. Respondents to the September Survey of Nebraska Business reported plans to increase both sales and employment at their businesses over the next six months. Manufacturing hours-worked …

Foreign Capital Inflows And Economic Well-Being: A Statistical Analysis Of 46 Sub-Saharan African Countries From 1995-2015, Alexander M. Csanadi

Undergraduate Economic Review

Variation in the economic well-being among sub-Saharan African countries is among the highest of any region in the world. This paper attempts to address this disparity by exploring the role of foreign capital inflows. This project extends the concept of well-being beyond GDP growth, to include measures of poverty and inequality. A multivariate regression analysis finds that the observed capital inflows have significant effects on all three measurements of well-being. Findings suggest that the level of affluence of the domestic population has significant effects on the ability of those populations to translate diaspora remittances into improvements in well-being.
