The Weekend Effect In Television Viewership And Prime-Time Scheduling, Jung Won Yeo

Research Collection School Of Economics

The observed drops in the ratings of television programs on Fridays and Saturdays are likely a result of two factors: intrinsic contraction in demand for television watching and endogenous scheduling. I decompose the observed weekend effect into the effects from these two factors. To this end, I estimate a viewer choice model that uses aggregate Nielsen ratings data for prime-time network television shows over 11 years. The long span of the data enables me to control for television series qualities. The estimation results reveal that the estimated weekend effect is dampened as the empirical model accounts for variation in the …

Does "America First" Help America? The Impact Of Country Image On Exports And Welfare, Pao-Li Chang, Tomoki Fujii, Wei Jin

Research Collection School Of Economics

This paper estimates the effects of bilateral and time-varying preference bias on trade flows and welfare. We use a unique dataset from the BBC World Opinion Poll that surveys (annually during 2005-2017 with some gaps) the populations from a wide array of countries on their views of whether an evaluated country is having a mainly positive or negative influence in the world. We identify the effects on bilateral preference parameters due to shifts in these country image perceptions, and quantify their general equilibrium effects on bilateral exports and welfare (each time for an evaluated exporting country, assuming that the exporting …

Random Mechanism Design On Multidimensional Domains, Shurojit Chatterji, Huaxia Zeng

Research Collection School Of Economics

We study random mechanism design in an environment where the set of alternatives has a Cartesian product structure. We first show that all generalized random dictatorships are strategy-proof on a minimally rich domain if and only if the domain is a top-separable domain. We next generalize the notion of connectedness (Monjardet, 2009) to establish a particular class of top-separable domains: connected domains, and show that in the class of minimally rich and connected domains, the multidimensional single-peakedness restriction is necessary and sufficient for the design of a flexible random social choice function that is unanimous and strategy-proof. Such a flexible …

Evaluating The Empirical Performance Of Dsge Models: What Is The Role Of Search And Matching Frictions In The Labor And Capital Markets?, Weng Sam Mok

Dissertations and Theses Collection

A major perspective in explaining involuntary unemployment is to recognize the existence of job market frictions, in particular, job market matching frictions. The workhorse model employed is the Diamond- Mortensen-Pissarides (DMP) model. Similar to the labor market, the market for physical capital markets exhibits the same characteristics with a pool of unsold inventory as well as used capital that is sold and reallocated to other terms. Nevertheless, past research has highlighted several issues of the DMP model in matching the characteristics of the labor market. In a model enriched with labor participation flows and job separation, I evaluate the model …

On The Relationship Between Household Wealth And Entrepreneurship, Jungho Lee

Research Collection School Of Economics

Motivated by a substantial number of startup owners with negative household net worth, I present a model that incorporates credit borrowing into Evans and Jovanovic [1989]. The estimated model generates no relationship between household wealth and the propensity for business entry. Ignoring credit borrowing for potential business owners substantially overstates the efficiency loss from financial constraints in business entry. However, the efficiency loss in investments by the entrants is large even if credit borrowing is allowed. Individuals who start a business once credit borrowing is available are those whose business ideas are of a high-enough quality to compensate high financing …

On Random Assignment Problems, Peng Liu

Dissertations and Theses Collection

This dissertation studies the standard random assignment problem (Bogomolnaia and Moulin (2001)) and investigates the scope of designing a desirable random assignment rule. Specifically, I ask the following two questions:

1. Is there a reasonably restricted domain of preferences on which there exists an strategy-sd-efficient proof, sd-efficient and sd-envy-free or equal-treatment-of-equals rule?

2. Moreover, if the answer is in the affirmative, what is that rule?

As a starting point, attention is restricted to the connected domains (Monjardet (2009)). It is shown that if a connected domain admits a desirable random assignment rule, it is structured in a specific way: a …

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy

Research Collection School Of Economics

We use a household-level panel dataset from Bangladesh to examine the household-level relationship between fertility and the access to electricity. We find that the household's access to electricity reduces the change in the number of children by about 0.1 to 0.25 children in a period of five years in most estimates. This finding also applies to retrospective panel data and is robust to the choice of covariates and estimation methods. Our finding passes falsification test and corroborates with the predictions of our theoretical model on the households' time use and consumption pattern.

Singapore’S Life Program: Actuarial Framework, Longevity Risk And Impact Of Annuity Fund Return, Koon Shing Kwong, Yiu Kuen Tse, Wai-Sum Chan

Research Collection School Of Economics

The Central Provident Fund (CPF) is a defined-contribution savings plan forming the key pillar of the pension system in Singapore. The CPF Lifelong Income For the Elderly (LIFE) program, which provides lifetime income for retirees, is a mandatory pension scheme for all Singapore residents. In this paper we construct an actuarial framework to analyze the LIFE program. We use this framework to study the plan payout outcomes with respect to changes in mortality and annuity fund return assumptions. We also examine the effects of some possible changes in the program on the payouts and bequests.

A Martingale Difference-Divergence-Based Test For Specification, Liangjun Su, Xin Zheng

Research Collection School Of Economics

In this paper we propose a novel consistent model specification test based on the martingale difference divergence (MDD) of the error term given the covariates. The MDD equals zero if and only if error term is conditionally mean independent of the covariates. Our MDD test does not require any nonparametric estimation under the alternative and it is applicable even if we have many covariates in the regression model. We establish the asymptotic distributions of our test statistic under the null and a sequence of Pitman local alternatives converging to the null at the usual parametric rate. Simulations suggest that our …

Love, Money, And Parental Goods: Does Parental Matchmaking Matter?, Fali Huang, Ginger Zhe Xu, Lixin Colin Xu

Research Collection School Of Economics

While parental matchmaking has been widespread throughout history and across countries, we know little about the relationship between parental matchmaking and marriage outcomes. Does parental involvement in matchmaking help ensure their needs are better taken care of by married children? This paper finds supportive evidence using a survey of Chinese couples. In particular, parental involvement in matchmaking is associated with having a more submissive wife, a greater number of children, a higher likelihood of having any male children, and a stronger belief of the husband in providing old age support to his parents. These benefits, however, are achieved at the …

Local And Global Sd-Strategy-Proofness Of Ordinal Mechanisms On Block-Connected Domains, Peng Liu

Research Collection School Of Economics

The adjacency by Monjardet (2009) is weakened to a flip between two adjacently ranked blocks and called block-adjacency. The connectedness defined accordingly, blockconnectedness, covers some interesting unconnected domains. An ordinal mechanism on a block-connected domain is block-adjacent sd-strategy-proof if reporting the true preference always leads to a lottery that stochastically dominates the lottery delivered by reporting any preference block-adjacent to the sincere one.A condition on a block-connected domain called path-nestedness is proposed and shown sufficient for the equivalence between sd-strategy-proofness and block-adjacent sd-strategy-proofness. The sequentially dichotomous domain by Liu (2017) is an application. In addition, we systematically search for the …

Retirement Adequacy Of Mature Workers In Singapore, Rhema Vaithianathan, Stephen Hoskins

Research Collection School Of Economics

In the last decade, the Singapore resident population has grown older with more elderly and fewer younger people. As Singapore Department of Statistics noted, the proportion of residents aged 65 years and over has increased from 9% to 13% over the past ten years. There are now fewer working-age adults to support each resident aged 65 years and over as indicated by the falling resident old-age support ratio from 7.7 in 2007 to 5.1 in 2017. The support ratio is expected to halve to 2.5 by 2030. As Singaporeans are both living and working longer, it is vital for the …
