Social Trust, Cooperation, And Human Capital, Fali Huang Jan 2004

Social Trust, Cooperation, And Human Capital, Fali Huang

Research Collection School Of Economics

The importance of social trust on economic growth has been suggested by many empirical works. This paper formalizes the concept of social trust and studies its formation process in a game theoretic setting. It provides plausible explanations for a wide range of empirical and experimental findings. The main results of the paper are as follows. For utility-maximizing players, cooperation arises in one-period prisoner’s dilemmas if and only if there is social trust. The amount of social trust in a given game is determined by the distribution of players’ cooperative tendency. Cooperative tendency is in essence a component of human capital …


Congestion Control And Vehicle Ownership Restriction: The Choice Of An Optimal Quota Policy, Winston T. H. Koh Jan 2004

Congestion Control And Vehicle Ownership Restriction: The Choice Of An Optimal Quota Policy, Winston T. H. Koh

Research Collection School Of Economics

Singapore introduced a vehicle quota system (VQS) in 1990 as part of its overall policy to control urban congestion. While the VQS has reduced the annual growth rate of the vehicle population to about 3 per cent, it has created uncertainty in the cost of vehicle ownership due to the fluctuations in licence prices. This paper discusses three issues relating to the optimal design of a VQS: licence transferability, sub-categorisation, and the choice of an auction format. The analysis shows that licence transferability is not unambiguously desirable, sub-categorisation is highly regressive, and an open auction format results in less aggressive …


Open Versus Sealed-Bid Auctions: Testing For Revenue Equivalence Under Singapore's Vehicle Quota System, Winston T. H. Koh, Roberto S. Mariano, Yiu Kuen Tse Aug 2003

Open Versus Sealed-Bid Auctions: Testing For Revenue Equivalence Under Singapore's Vehicle Quota System, Winston T. H. Koh, Roberto S. Mariano, Yiu Kuen Tse

Research Collection School Of Economics

Using data from the auction of vehicle quota licenses in Singapore, we study if revenue equivalence holds when the auction format was switched from a sealed-bid format (May 1990 to June 2001) to an open bidding format since July 2001. Our econometric analysis indicates the change in auction format led to a change in bidding behavior. On average, the quota license premium under the open bidding format is about US$1,000 (about 7.5% of the Category E license price in June 2001) lower, compared to the forecast level that would have prevailed if there had been no change in the auction …


The Shapley-Shubik Index, The Donation Paradox And Ternary Games, Vincent C. H. Chua, H. C. Huang Jun 2003

The Shapley-Shubik Index, The Donation Paradox And Ternary Games, Vincent C. H. Chua, H. C. Huang

Research Collection School Of Economics

In this paper, we show that although the Shapley-Shubik index is immune to the donation paradox in weighted binary games, extension of the index to ternary games along the direction suggested in Felsenthal and Machover (1996, 1997) will cause it to be vulnerable to the paradox and this is the case as long as the number of players in the game exceeds three. This undermines the attractiveness of the Shapley-Shubik index as a measure of a priori voting power.


The General Dominance Of Lottery Over Waiting-Line Auction, Winston T. H. Koh, Zhenlin Yang, Lijing Zhu Sep 2002

The General Dominance Of Lottery Over Waiting-Line Auction, Winston T. H. Koh, Zhenlin Yang, Lijing Zhu

Research Collection School Of Economics

This paper examines the allocative efficiency of two popular non-price allocation mechanisms — the lottery (random allocation) and the waiting-line auction (queue system) — for the cases where consumers possess identical time costs (the homogeneous case), and where time costs are correlated with time valuations (the heterogeneous case). We show that the relative efficiency of the two mechanisms depends critically on the scarcity factor (measured by the ratio of the number of objects available for allocation over the number of participants) and on the shape of the distribution of valuations. We obtain a set of analytical results showing that the …


Optimal Organizational Design In A Dichotomous-Choice Project Selection Model, Winston T. H. Koh Jul 2002

Optimal Organizational Design In A Dichotomous-Choice Project Selection Model, Winston T. H. Koh

Research Collection School Of Economics

This paper studies collective decision making in the context of a project selection model. We derive the optimal decision architecture when marginal decision costs are present, and investigate the circumstances under which the hierarchy and polyarchy exist as optimal sequential architectures. Our analysis extends previous results on optimal committee decision-making to a sequential setting, and further demonstrates the fragility of the hierarchy and polyarchy as optimal architectures.


How Does Spousal Education Matter? Some Evidence From Cambodia, Tomoki Fujii, Sophal Ear Jan 2002

How Does Spousal Education Matter? Some Evidence From Cambodia, Tomoki Fujii, Sophal Ear

Research Collection School Of Economics

An econometric analysis of the World Food Programme Civil Insecurity Baseline Survey (1998) and Cambodia Socio-Economic Survey (1999) data is undertaken to examine the role of education and literacy in explaining household expenditure, as hypothesized in human capital theory where education is an investment with returns in the form of income. Explanatory variables were selected from a large set of observed variables by a systematic procedure to avoid the bias arising from arbitrary model selection. Spousal education and literacy are found to be significant explanatory variables in the determination of household expenditure, exceeding even the coefficients attached to the head …


Mapping The Discipline Of The Olympic Games: An Author Cocitation Analysis, Peter Warning, Rosie Ching, Kristine Toohey Apr 2001

Mapping The Discipline Of The Olympic Games: An Author Cocitation Analysis, Peter Warning, Rosie Ching, Kristine Toohey

Research Collection School Of Economics

The authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the …
