    Abstract The Keenjhar Lake, Pakistan’s largest freshwater lake and a Ramsar site, is located in the Lower Indus Basin of the Indus Ecoregion. Global 200, which scientifically ranks outstanding terrestrial and aquatic ecosystems in 238 ecoregions worldwide, the Indus Ecoregion is one of the 40 priority Ecoregions. This study uses a single-site truncated count data travel cost method to estimate the access values of visitors to Keenjhar Lake. Policy makers may use these estimates on the recreational value of the lake to assess the returns on conservation investments. A basic version of the model applied to a subset of visitors using charter transportation allows analysis of impacts on welfare measurement from altering assumptions about embarkation points. This study finds the assumption that this category of visitor does not incur travel and time costs before boarding charter transport to be both unrealistic and simplifying, leading in turn to an underestimate of consumer surplus values. The strongest argument in favour of revising data collection and processing strategies in this regard is perhaps the finding that shared and rented transportation is common in developing countries, while cost coefficients tend to figure prominently in welfare measurement irrespective of the functional form.

    Abstract Exchange rate behaviour does not follow very obvious and predicted pattern. Many attempts have been made to predict its behaviour as much as possible. This research re-examines the Dornbusch’s model of exchange rate overshooting caused by price rigidities. Dornbusch’s assumption of full employment in economy has been violated in this research which creates the possibility of exchange rate undershooting. In response to positive monetary shock, interest rate decreases and exchange rate undershoots its long run equilibrium. This research explains the dynamics of anti-intuitive exchange rate undershooting. Apart from theoretical formations of exchange rate undershooting, this research also analyses Pakistani data for exchange rate undershooting or overshooting in response to increase in money supply. Quarterly data of twenty three years for exchange rate, nominal interest rate, price, real output and money have been taken and vector autoregressive technique has been used. Evidence of exchange rate undershooting in response to positive money supply shock was found. It also gives an important insight into policy making by identifying some probable behaviour of exchange rate.

    An Indigenous Technique of Water Conservation for Food Security in Gilgit-Baltistan, Pakistan

    Abstract Climate change and disruption in the water cycle patterns are leading to water scarcity. This unsustained water provision is drastically affecting the areas of limited water resources. This research has studied the impacts of climate change on water availability and the localized indigenous technique of glacier grafting for sustained water provision. This adaptation strategy helps the water-stressed locality to conserve water for food security. For this reason, 160 self-administered questionnaires were deployed at the household level, and the primary data were analyzed through STATA Software for ordinal logit regression to estimate the results for both restricted and unrestricted models, against the three dependent variables of glacier grafting, glacier melt water and food security. It is found that glacier grafting ensures sustained water provision for irrigation. It increases fertile land and agricultural production to achieve food security. The income of the households from non-/agricultural products leads to afford a better standard of living. The extension of the glacier grafting strategy to curb climatic effects can help global societies to address the food insecurity issue for sustained living.

    Abstract Tukey’s boxplot is very popular tool for detection of outliers. It reveals the location, spread and skewness of the data. It works nicely for detection of outliers when the data are symmetric. When the data are skewed it covers boundary away from the whisker on the compressed side while declares erroneous outliers on the extended side of the distribution. Hubert and Vandervieren (2008) made adjustment in Tukey’s technique to overcome this problem. However another problem arises that is the adjusted boxplot constructs the interval of critical values which even exceeds from the extremes of the data. In this situation adjusted boxplot is unable to detect outliers. This paper gives solution of this problem and proposed approach detects outliers properly. The validity of the technique has been checked by constructing fences around the true 95% values of different distributions. Simulation technique has been applied by drawing different sample size from chi square, beta and lognormal distributions. Fences constructed by the modified technique are close to the true 95% than adjusted boxplot which proves its superiority on the existing technique.
