Evidence from a Cross-Country Analysis Kumara, A.S. This study employs the instrumental variable two-stage least squares regression approach for the data for 121 countries to explore the impact of a country’s political environment on its level of corruption. The study provides strong evidence that a higher degree of rule of law, press freedom, readiness and capacity to handle e-governance practices, and urbanization are associated with a lower level of public sector corruption across all 121 countries. The colonial dummies and having a presidential government are found to be valid instruments for rule of law in addressing the issue of endogeniety embedded in it. Further, to a certain degree, landlocked countries are relatively more corrupt than coastal countries. Finally, policy implications are discussed based on the findings of the study. 2014-01-01T00:00:00Z http://dr.lib.sjp.ac.lk/handle/123456789/5327 Evolution of the Methodology of Technical and Allocative Efficiency Studies in Economics: A Review of Literature Rathnayake, R.M.A.K.; Amarathunge, S.P.P. Efficiency measurements have been a great concern of researchers with an aim to study the efficiency levels of almost all economic activities. Empirical estimation and identifying the determinants of efficiency are the major tasks in efficiency analysis. The main objective of this study is to investigate major changes taken place in the methodology of technical and allocative efficiency in economics. The historical approach is used as the methodology of this study. There was no accepted statistical methodology to measure economic, technical and allocative efficiencies until the study of Farrell (1957); “The Measurement of Productive efficiency”. In economics, economic efficiency has two components which are referred to as technical efficiency and allocative efficiency. Technical efficiency is associated with the ability to produce on the frontier isoquant, while allocative efficiency refers to the ability to produce at a given level of output using the cost-minimizing input ratios. Few alternative parametric methods are available in literature such as production, cost, profit, revenue and distance functions to analyze efficiency by estimating production technology. The nonparametric methodology involves mainly the use of linear programming techniques. According to available literature, it is clear that various approaches to efficiency analysis have been developed by two parallel traditions, the econometric method and the non-parametric data envelopment analysis. Each of these traditions incorporate its inherent merits and demerits. Findings of the study reveal that input distance function is the best methodology for measuring allocative efficiency if inputs quantities do not significantly vary across units of studies. 2014-01-01T00:00:00Z http://dr.lib.sjp.ac.lk/handle/123456789/5326 Investigating the Existing Level of Tourists’ Destination Satisfaction; a Case of Tourists’ Travel Experience in Sri Lanka Lakmali, A.A.I.; Warnakulasooriya, N.B.F. Tourists’ designation satisfaction on destination attributes plays an important role in marketing tourism products and services. Therefore, determinants of tourists’ destination satisfaction are an ongoing debate in academic literature since destination attributes available in different destinations are heterogeneous. Thus, the objective of this research is to provide empirical evidence on tourists’ existing level of satisfaction on destination attributes in Sri Lanka. The study applies an empirical model with five destination attributes; Destination attractions, Food & Beverage Services, Tourism Price Level, Hospitality, Political and Social Factors to determine tourists’ destination satisfaction in Sri Lanka. Judgmental sampling technique was utilized to select 251 tourists from seven countries who had recently visited Colombo, Galle and Kandy locations in Sri Lanka. Data were collected via a researcher administrated questionnaire. One sample T test, Mean scores and ANOVA were used to analysis the tourist destination satisfaction. Further, analysis involved statistical methods such as reliability and validity tests. The results revealed that tourist are moderately and highly satisfied with on destination attributes; destination attractions, tourism price level and food & beverage services, hospitality and social and political factors in terms of the tourists’ country of origin. The implications were tourists who visited Sri Lanka were satisfied with the five attributes used for this study. Further, tourists’ country of origin has impact on tourists’ satisfaction with destination attributes. Therefore, tourism authorities should be strategically identified that what are the destination attributes seek by tourists’ in terms of their country of origin and improve them. 2014-01-01T00:00:00Z http://dr.lib.sjp.ac.lk/handle/123456789/5325 Determinants of Interest Rates: The Case of Sri Lanka Peiris, H.R.I.; Jayasinghe, P. Many studies have looked in to the determinants of interest rate in developed countries. The objective of this paper is to examine the determinants of interest rates in Sri Lanka. The model employed in this study is based on the framework developed in Edwards and Khan (1985) and a few modifications suggested in Cavoli (2007), Cavoli and Rajan (2006), Berument, Ceylan and Olgun (2007) and Zilberfarb (1989). The model nests the interest rate parity theory, liquidity preference theory and the Fisher hypothesis augmented with inflation uncertainty. We employ Autoregressive Distributed Lag (ARDL) approach to capture long-run relationships among the variables involved. Quarterly data from 2001:1 to 2012:2 has been used. There are a few important findings. First, there is no evidence for inflation uncertainty in Sri Lanka during the sample period concerned. Second, the ARDL bound testing approach suggests that there is no long-run impact of the national income, money supply, inflation, foreign interest rates and net foreign assets on the domestic interest rate. Third, apart from the interest rate parity conditions, neither the liquidity preference theory nor Fisher effect is useful in explaining short-run interest rate changes in Sri Lanka during the period in question. 2014-01-01T00:00:00Z
