Potato cultivation accounts for 5.71 percent in total cropped area of the Punjab province and it supplements the diet of the growing population at lower prices as compared to grains, meat and chicken. Data from 100 farmers, 50 each from the districts of Okara and Kasur during the year 2002-2003 (the autumn crop) has been collected. The study estimates the technical efficiency in potato production by employing the Cobb-Douglas stochastic production frontier approach. The null hypothesis of no technical inefficiency in the data is rejected. Our results indicate that potato farmers are 84 percent technically efficient, implying significant potential in potato production that can be developed. By shifting the average farmer to the production frontier, the average yield would increase from 8.33 tons per acre to 9.92 tons per acre using the available resources. The additional quantity of potatoes gathered through efficiency improvements would generate Rs. 990.81 ($16.51) million of revenue each year. Consultation with extension workers significantly contributes to the improvement of technical efficiency and implies that the extension department should be one of the major targeted variables from the policy point of view in order to improve technical efficiency in potato production.

This paper investigates the technical efficiency of selected manufacturing industries of Bangladesh using a stochastic frontier production function approach suggested by Battese and Coelli (1992) applied to panel data. A feasible Cobb-Douglas stochastic frontier production function, which has time-varying technical inefficiency effects, was estimated. Two alternative distributions were used to model the random inefficiency term: a truncated normal distribution and a half-normal distribution. The estimated average technical efficiency for four groups of industries of Bangladesh over the reference period was 40.22% of potential output for the truncated normal distribution, whereas it was 55.57% of potential output for the half-normal distribution.

This study, which is among the first in Pakistan to value recreational benefits, estimates the benefits of the Margalla Hills National Park near Islamabad. The study examines how much park visitors are willing to pay to visit the park. Annual benefits from the park are considerable—the total annual consumer surplus or economic benefit obtained from recreation in the park is approximately Rs. 23 million (US $ 0.4 million). Various factors influence the value visitors obtain from the park — these include travel cost, household income, and the quality of the park. Improvements in the quality of the park are estimated to increase recreational benefits by 39%. The study recommends that a park entrance fee of Rs. 20 per person be introduced, which could be utilized for park management. This would generate nearly Rs. 11 million in revenues annually, a sizable amount of money that represents about 4% of the annual budget allocated to the environment sector in Pakistan.

This paper examines the existence of a long-run relationship between population and per capita income in Pakistan for the period 1960-2001 using cointegration analysis. Unit root results show that population is integrated of order zero while per capita income is integrated of order one; further, Johansen’s procedure show that no long-run cointegrating relationship exists. Thus, population growth neither causes per capita income growth nor is caused by it. A corollary is that population growth neither stimulates per capita income growth nor reduces it.

This study examines the regulatory intervention in India and Pakistan in response to episodes of excessive market volatility and manipulation and its effectiveness in achieving declared objectives. Our empirical analysis indicates that while the Indian regulatory agencies seem to have achieved their objectives in curtailing manipulative and speculative behavior, there appears to be little impact on such behavior in the case of the Karachi Stock Exchange. Significant differences in the regulatory effectiveness and industry structure may explain the difference in the market behavior outcomes following regulatory interventions. A stronger competitive environment in India, because of the existence of multiple organized exchanges, seems to facilitate effective enforcement of public policy.

This paper focuses on the role of the financial futures market in the volatility of Pakistan’s stock market and determines whether the stock futures price is capable of providing some relevant information for predicting the spot price. The Generalized Autoregressive Conditional Heteroscedasticity (GARCH) approach is used to measure volatility in the spot and the futures market and to analyze the relationships between spot and futures market volatility. Causality and feedback relationships between the two markets are analyzed and determined through the Vector Error Correction Model (VECM). Empirical results support the evidence that spot prices generally lead the futures prices in incorporating new information, and that volatility in the futures market does not increase volatility in the spot market. Rather the study finds more consistent support for the alternative hypothesis that volatility in the futures market may be an outgrowth of the volatile spot market.

This paper investigates the calendar anomalies in the Singapore stock market over the recent period from 1993-2005. Specifically, changes in stock index returns are examined surrounding January (the January effect), on different days of the week (the day-of-the-week effect), around the turn of the month (the turn-of-the-month effect) and before holidays (the pre-holiday effect). The findings reveal that these anomalies have largely disappeared from the Singapore stock market in recent years. The disappearance of these anomalies has important implications for the efficient market hypothesis and the trading behavior of investors.

Consistent with asymmetric information arguments, prior research has shown that the financial market typically responds negatively to the announcement of a seasoned equity offering (SEO). Korajczyk and Levy (2003), however, suggest that while some firms time the issuance of their common stock to take advantage of outside investor overvaluations, financially constrained firms do not. We examine whether prior information on how financially constrained a firm is along with its growth prospects influences the financial market’s response to the firm’s announcement to sell common stock. We find evidence that the financial market does condition its response upon such information using a sample of SEOs from the U.S. Our results also have implications for the financial market’s reaction to SEOs/rights offerings in emerging markets.

This paper is an ethnographic study defining and assessing the organizational culture exhibited by Small and Medium Enterprises (SMEs). It primarily focuses on four cultural categories: clan, adhocracy, hierarchy and market-driven. These conceptual domains have been examined by the Organizational Culture Assessment Instrument. Results from a sample of 162 SMEs in the Rawalpindi/Islamabad area indicate that SME culture lacks creativity, innovation, freedom and risk taking. SMEs are not looking to change in the future, preferring the status quo. The most important finding is that SMEs exhibit a market- oriented culture focusing on results, competition and achievements.

This note discusses the workings of the Dispute Settlement Process (DSP) of the WTO, and the major problems concerning the implementation of decisions in the DSP. It provides some suggestions in order for the DSP to work for the benefit of all. It maintains that the ability to extend dispute settlement across agreements is one of the strengths of the World Trade Organization. The author concludes that substantial reform can be undertaken in the DSP if concerted efforts are made to quantify economic damages for working out the suspension of concessions.
