Since the REIT industry is relatively new in Singapore, the objective of this research is to examine the operation efficiency among firms in the industry through the method of Data Envelopment Analysis (DEA). In addition, the method of Tobit regression is applied to investigate the impact factors on efficiency. The results are as follows. First, none of 14 firms analyzed performs relatively efficiently based on the average efficiency scores over the sample periods of 2007 to first quarter of 2015. Nevertheless, it is found that First REIT and Suntec REIT are the most efficient and least efficient REITs respectively. Second, ROA is positively correlated to efficiency scores while the negative relationship is found with the debt ratio. Third, regarding property-type, retail REITSs perform better than commercial ones on average. However, the most efficient group is "others" which consists of one hospitality/residential REITs, one healthcare REITs, and three industrial REITs. Fourth, geographical diversification may not affect REIT's efficiency. Meanwhile, REITs holding more properties overseas perform better than their counterparts on average. Last, in regards to size, small-size REITs significantly perform better in efficiency than those in other categories. Especially, medium-size and largesize REITs do not have significant differences on average in efficiency.

The objective of this research is to conduct an empirical analysis of the relationship between Economic Growth and Regional trading in the CARICOM region. In this research Economic growth is measured by annual Gross Domestic Product (GDP) and annual Gross National Income (GNI) which is employed as the dependent variable. The economic index variables also applied in this study are the unemployment rate, import, export, total regional trade value, population, and classification. The study's findings indicated a positive relationship between Total Regional Trade value and GDP in the Caribbean region. The study also indicated a positive relationship between Regional Trade Flow and GNI. Additionally, there was a positive relationship between imports and the unemployment rate. However, exports had no impact on the unemployment rate. Also, a country’s categorization had no impact on total trade value. Throughout the investigation, the implications of the discoveries are thoroughly discussed.

Commercial loan borrowers meet random cash needs via multi-period loans from the bank, but fluctuations in interest rates may justify paying off some outstanding loans before they mature. The objective is to minimize the expected present value of the interest and prepayment penalties paid to the bank subject to a liquidity constraint. From Chiang (2005), it is shown that a firm should not inventory cash if contingent opportunities are ignored. By extending her article, it is also found that if a borrower is not risk neutral, a more risk-averse borrower prepays a larger amount.
