This paper discusses the efforts by the Government of Pakistan to implement a General Sales Tax (GST). First, a history of Pakistani tax reform efforts is presented along with the reforms recommended by the National Taxation Reforms Commission. After this, the design and implementation of the GST is discussed followed by an analysis of the political economy and provincial issues that arise in the process of implementing the GST. Finally, the paper discusses various proposals regarding the determination of the base for the GST. The paper concludes that the splitting of the GST by sectors, given the perspective that the 1930’s style sales tax, is not sensible, and the Pakistani formulation is more unstable than the assignment of the GST on goods.

This paper explores how Pakistan can get out of the low-tax-to-GDP trap and come close to achieving its revenue targets. Examining the trend factors influencing the trend in total and individual tax-to-GDP ratios over a period of twenty years, the paper concludes that partially successful and/or inappropriate tax reforms have put Pakistan in this trap. While highlighting that a period of economic slowdown may not be the best time to make a big push on resource mobilization, the paper presents a strategy which aims at not only enhancing tax revenues but also making the taxation structure more progressive, broad based and balanced.

This paper looks at the Indus Basin Water Strategy for Pakistan. It begins with a historical overview of the Indus Basin Irrigation System (IBIS), the Indus Basin Replacement Works (1960-1980) and the Indus Basin Salinity Control Efforts (1960-2000). The paper then looks at the IBIS irrigation and salinity control investments that have taken place over the last decade (2000-2010). The paper goes on to look at the present situation of the IBIS as well as discuss an IBIS strategy for the next decade. Finally, the paper discusses supply side and demand management strategies for IBIS. Overall, the paper concludes that Pakistan should focus on (1) Creating Additional Surface Storage, (2) Preserving surface water (particularly through lining canals), (3) Controlling Groundwater and controlling salinity (by discouraging excessive tube-well use), (4) Encouraging general efficiency of irrigation water use (through improved land management techniques), (5) Enhancing yields through improved farming practices, and (6) Fully meeting the environmental concerns of the Indus Delta, river systems and wetlands.

This article is an attempt to examine the short and long-run relationship between the trade balance, income, money supply, and real exchange rate in the case of Pakistan’s economy. Income and money variables are included in the model in order to examine the monetary and absorption approaches to the balance of payments, while the real exchange rate is used to evaluate the conventional approach of elasticities (Marshall Lerner condition). The bounds testing approach to cointegration and error correction models, developed within an autoregressive distributed lag (ARDL) framework is applied to annual data for the period 1970 to 2005 in order to investigate whether a long-run equilibrium relationship exists between the trade balance and its determinants. Additionally, variance decompositions (VDCs) and impulse response functions (IRFs) are used to draw further inferences. The result of the bounds test indicates that there is a stable long-run relationship between the trade balance and income, money supply, and exchange rate variables. The estimated results show that exchange rate depreciation is positively related to the trade balance in the long and short run, consistent with the Marshall Lerner condition. The results provide strong evidence that money supply and income play a strong role in determining the behavior of the trade balance. The exchange rate regime can help improve the trade balance but will have a weaker influence than growth and monetary policy.

Using an international dataset on bilateral trade for 137 countries in 2005, we estimate a gravity model to address the question of whether intra-Economic Cooperation Organization (ECO) trade is too low and whether the scale of trade at present is accounted for by regional integration or unilateral liberalization. The results of the gravity model confirm that intra-regional trade is lower than predicted by the gravity equation. The results also validates the theory that the present level of trade is attributed to regional agreements rather than unilateral liberalization, suggesting greater scope for regional cooperation among ECO member countries.

This paper studies the impact of changes in the external balance of Pakistan. We explain why the economic growth achieved during the past decade was highly dependent on improvements in the external balance. Between 2001 and 2007, Pakistan benefited from an increase in remittances, foreign assistance from bilateral and multilateral sources, and a relatively stable exchange rate. After 2007, this performance came under pressure from external price shocks. The rise in the import prices of petroleum, raw materials and other manufactured goods has the potential to reduce the country’s growth performance, impacting the competitiveness of the economy and threatening the gains achieved during past years. We integrate a computable general equilibrium (CGE) model with a microsimulation model to study the effects of changes in foreign savings and import prices faced by Pakistan. An increase in foreign savings leads to an increase in imports and a decrease in exports. The main sectors facing a decline in exports are textiles, leather, cement, and livestock. In this simulation food and oil prices decline and the factors of production that gain are agricultural wage labor and nonagricultural unskilled wage labor. The increase in import prices of petroleum or industrial raw material leads to a reduction in exports. In this simulation the crop sector is negatively impacted and returns to land and profits to farm owners increase, showing a change in favor of agricultural asset owners, while poverty and inequality increase.

A simultaneous-equations model was used to capture the supply and demand functions for Pakistan’s wheat sector at the national level. This model reflects the fact that Pakistan’s domestic wheat supply is priceresponsive and positively affected by the use of nutrient fertilizers. While price appears to be a statistically significant factor on the supply side, it is statistically insignificant on the demand side. Population size appears to be very significant in determining wheat demand. The wheat import supply seems to be influenced by the current world wheat price, current world wheat supplies, Pakistan’s domestic consumption in previous years, and domestic supply in previous years. We recommend that policymakers allow market forces to play a role in the wheat economy in a way that protects producers from adverse market conditions. The availability of various nutrient fertilizers should be central to policies on future inputs use. Work is also needed on wheat alternatives so that the country’s dependence on wheat is eased as much as possible.

This study tests the semi-strong form of market efficiency by investigating the reaction of stock prices to dividend announcements. It analyzes cash, stock, and simultaneous cash and stock dividend announcements of 79 companies listed on the Karachi Stock Exchange from July 2004 to June 2007. Abnormal returns from the market model are evaluated for statistical significance using the t-test and Wilcoxon Signed Rank Test. The findings suggest negligible abnormal returns for cash dividend announcements. However, the average abnormal and cumulative average abnormal returns for stock and simultaneous cash and stock dividend announcements are mostly positive and statistically significant.

In many countries, capital markets are often served by multiple stock exchanges, typically with one national or dominant exchange and several regional or satellite exchanges. While multiple exchanges create a competitive landscape, they also lead to fragmented liquidity and diseconomies in operations. This paper examines the role of the Lahore Stock Exchange (LSE) in comparison with the country’s dominant exchange, the Karachi Stock Exchange (KSE), in four areas: (i) market efficiency in processing information, (ii) transaction costs, (iii) contribution to price discovery, and (iv) market integration. A comparative analysis of the exchange performance indicates the two exchanges to be at par in terms of informational efficiency and transaction costs. There is evidence of informational linkages and interdependencies between the two exchanges; the LSE appears to contribute to price discovery and competes to an appreciable extent. Against the background of proposals to merge the country’s three stock exchanges, a major consideration in evaluating public policy is the relative performance of the LSE and its viability as an effective competitor. Eliminating inter-exchange competition by merging the stock exchanges is predicted to lead to higher transaction costs, lower incentives for regulatory compliance, and diminished motivation for promoting capital market development.
