Contracting Over Prices, Shurojit Chatterji, Sayantan Ghosal Dec 2012

Contracting Over Prices, Shurojit Chatterji, Sayantan Ghosal

Research Collection School Of Economics

We define a solution concept, perfectly contracted equilibrium, for an intertemporal exchange economy where agents are simultaneously price takers in spot commodity markets while engaging inefficient, non-Walrasian contracting over future prices. Without requiring that agents have perfect foresight, we show that perfectly contracted equilibrium outcomes are a subset of Pareto optimal allocations. It is a robust possibility for perfectly contracted equilibrium outcomes to differ from Arrow-Debreu equilibrium outcomes. We show that both centralized banking and retrading with bilateral contracting can lead to perfectly contracted equilibria.


Money And Asset Prices With Uninsurable Risks, Nicolas L. Jacquet, Serene Tan Dec 2012

Money And Asset Prices With Uninsurable Risks, Nicolas L. Jacquet, Serene Tan

Research Collection School Of Economics

We develop a model where the coexistence of money and a higher yielding asset is endogenously obtained when no restriction is placed on the use of either object as a medium of exchange. Due to the presence of uninsurable risks, agents have, in equilibrium, di⁄erent relative valuations of the asset to money, and hence, the use of money as a means of payment is strictly preferred. This endogenous di⁄erence in the willingness of agents to use money over the asset implies that money carries a greater liquidity premium than the asset. We obtain that the asset strictly dominates money in …

Detecting Bubbles In Hong Kong Residential Property Market, Matthew S. Yiu, Jun Yu, Lu Jin Aug 2012

Detecting Bubbles In Hong Kong Residential Property Market, Matthew S. Yiu, Jun Yu, Lu Jin

Research Collection School Of Economics

This study uses a newly developed bubble detection method (Phillips, Shi and Yu, 2011) to identify real estate bubbles in the Hong Kong residential property market. Our empirical results reveal several positive bubbles in the Hong Kong residential property market, including one in 1995, a stronger one in 1997, another one in 2004, and a more recent one in 2008. In addition, the method identifies two negative bubbles in the data, one in 2000 and the other one in 2001. These empirical results continue to be valid for the mass segment and the luxury segment. However, the method finds a …


Off The Cliff And Back? Credit Conditions And International Trade During The Global Financial Crisis, Davin Chor, Manova Kalina May 2012

Off The Cliff And Back? Credit Conditions And International Trade During The Global Financial Crisis, Davin Chor, Manova Kalina

Research Collection School Of Economics

We examine the collapse of international trade flows during the 2008-2009 global financial crisis using detailed data on the evolution of monthly U.S. imports over the November 2006 - April 2009 period. We show that credit constraints and the reduction in the availability of external capital were an important channel through which the crisis affected trade volumes. We identify the effects of credit tightening by exploiting the variation in the cost of capital across countries and over time, as well as the variation in financial dependence across sectors. We find that countries with higher interbank interest rates and thus tighter …


Out Of Sight, Out Of Mind: The Value Of Political Connections In Social Networks, Quoc-Anh Do, Yen Teik Lee, Bang Dang Nguyen, Kieu-Trang Nguyen May 2012

Out Of Sight, Out Of Mind: The Value Of Political Connections In Social Networks, Quoc-Anh Do, Yen Teik Lee, Bang Dang Nguyen, Kieu-Trang Nguyen

Research Collection School Of Economics

This paper investigates the impact of social-network based political connections on firm value. We focus on the networks of university classmates and alumni among directors of U.S. public firms and congressmen. Comparing firms connected to elected versus defeated politicians in the Regression Discontinuity Design of close elections from 2000 to 2008, we provide evidence that political connections enhance firm value. However, the value of political connections varies in a more complex way than expected. While connections to powerful members of the Senate generate strong positive impact on firm value, connections to newly elected congressmen are less valuable to firms than …


Beyond Catch-Up To New Growth Sources, Hian Teck Hoon Feb 2012

Beyond Catch-Up To New Growth Sources, Hian Teck Hoon

Research Collection School Of Economics

SMU Professor of Economics Hoon Hian Teck gave his take on the impact of the Budget announced last Friday and wrote that the 2012 Budget, in essence, recognises that Singapore is now making a transition from a phase of catch-up growth to being a mature economy. In this mature phase, Singapore needs new sources of growth, and policy interventions are necessary to boost the employability and wage earnings of low-wage and older workers. Professor Hoon is also Associate Dean at the SMU School of Economics.


Micro-Finance Competition With Motivated Mfis, Brishti Guha, Prabal Roy Chowdhury Feb 2012

Micro-Finance Competition With Motivated Mfis, Brishti Guha, Prabal Roy Chowdhury

Research Collection School Of Economics

In this paper we examine the effect of increased MFI competition, focusing on its implications for borrower targeting, both in the presence and the absence of double-dipping. In the absence of competition we find that the loans are more likely to go to relatively richer borrowers whenever inequality is not too large, and the technology is sufficiently convex. In the presence of competition, the results depend on whether double-dipping is feasible or not. In case double-dipping is not feasible, we find that the MFIs necessarily target the richer borrowers. Interestingly, it turns out that double-dipping may encourage the MFIs to …


Bayesian Hypothesis Testing In Latent Variable Models, Yong Li, Jun Yu Feb 2012

Bayesian Hypothesis Testing In Latent Variable Models, Yong Li, Jun Yu

Research Collection School Of Economics

Hypothesis testing using Bayes factors (BFs) is known not to be well defined under the improper prior. In the context of latent variable models, an additional problem with BFs is that they are difficult to compute. In this paper, a new Bayesian method, based on the decision theory and the EM algorithm, is introduced to test a point hypothesis in latent variable models. The new statistic is a by-product of the Bayesian MCMC output and, hence, easy to compute. It is shown that the new statistic is appropriately defined under improper priors because the method employs a continuous loss function. …
