A theoretical review Perera, W.; Kulendran, N. Attached; Prior studies have examined initial public offering (IPO) market performance in two different periods-short run and long run-in terms of two phenomena: the underpricing or short-run market phenomenon and the underperformance or long-run market phenomenon. Tofind out the possible theoretical reasons for the underperformance phenomenon, this study reviews the past literature on the long-run market performance ofIPOs. The evidence on long-run underperformance of IPOs is not as widespread as that of short-run underpricing ofIPOs. The previous researchers have explained long-run performance using behavioural theories, methodological issues and short-run underpricing theories. Some researchers have found that IPOs underperform marginally or have no abnormal performance in the long run; thus, they do not reject the market efficiency hypothesis in the long run. Others have reported that IPOs overperform or do not underperform in the longrun market. Still others have argued that underperformance disappears when different performance measures or methodologies are used. The rest have found that' IPOs underperform considerably in the long-run IPO market. However, the long-run underperformance ofIPOs is a debatable issue amongfinancial researchers because of their studies Iconflicting results and controversial findings.

Attached; This study estimates the technical and allocative efficiency o f paddy farming in Sri Lanka. Household-specific technical efficiencies were computed using cross-sectional data collected from the household survey conducted in 2014 using a Stochastic Frontier approach. The Cobb-Douglas functional form was adopted for the frontier production function and the distributional assumption made for the inefficiency term was half normal. The results o f this study show that the estimated mean technical efficiency of the farmers is 78.32 percent, suggesting there is a scope o f 21.68 percent to increase paddy productivity using present technology. The estimated Returns to Scale is 0.2806, which implies that a proportional increase in all factors o f production leads to a less than proportional increase in paddy productivity. Age, schooling, alcohol consumption, agricultural training, farmers' attitudes, and the distance between the land and the main watercourse are significant determinants o f technical efficiency. According to the analysis o f allocative efficiency, there exists inefficiency in allocating resources, where land and machinery resources are underutilised while labour is over utilised.
