A Sufficient Condition For The Tops-Only Property Of Strategy-Proof Social Choice Functions In The Case Of Two Voters, Huaxia Zeng

Dissertations and Theses Collection (Open Access)

In this thesis, we consider the standard voting model with a finite set of alternatives A and 2 voters, and address the following question: besides Domains D satisfying the

Property T (Chatterji & Sen (2011) ), what are other characteristics of domains that induce every strategy-proof and unanimous social choice function f : Dn → A to satisfy the tops-only property? We impose a minimal richness condition which ensures that for every alternative a ∈ A, there exists a preference ordering where a is maximal. We identify a more general condition on domains that is sufficient for strategy-proofness …

This paper analyses the Singapore foreign exchange market from a microstructure approach. Specifically, by applying and modifying the empirical methodology designed by Bollerslev and Melvin (1994), we examine the relationship between bid-ask spreads and the underlying volatility of the USD/SGD. Our data set comprises high-frequency USD/SGD tick data of three separate years (April-June 1989, April-May 2006, April-May 2009). We found that for the USD/SGD: i) the size of bid-ask spreads are positively related to the underlying exchange rate volatility; ii) the magnitude of the dependence on underlying volatility increases as tick volume increases; and iii) the size of the bid-ask …

Effects Of Free Trade Areas In Trade Promotion: Gravity Model Approach, Mona Jit Mui Lim

Dissertations and Theses Collection (Open Access)

Since the early 1990s, the world has seen a proliferation of Free Trade Agreements (FTAs). One of the key objectives of FTAs is to expand trade between or amongst its signatories. This study explores the intra-FTA and extra-FTA trade expansion capability of 3 types of FTA: North-North FTA (European Union (EU)-15 as a representative), North-South FTA (North America Free Trade Agreement (NAFTA) as a representative) and South-South FTA (Association of Southeast Asia Nations (ASEAN ) Free Trade Agreement (AFTA) as a representative). The study made an attempt to address the spread of such FTA-led trade expansion amongst the members and …

Testing Heterogeneity In Panel Data Models With Interactive Fixed Effects, Qihui Chen

Dissertations and Theses Collection (Open Access)

This paper proposes a test for the slope homogeneity in large dimensional panel data models with interactive fixed effects based on a measure of goodness-of-fit (R²). We first obtain, for each cross-sectional unit, the R² from the time series regression of residuals on the constant and observable regressors and then construct the test statistic R² as an equally weighted average of the cross-sectional R²'s. R̄² is close to 0 under the null hypothesis of homogenous slopes and deviates away from 0 otherwise. We show that after being appropriately centered and scaled, R^{2 …}
