This study examines the impact of corporate tax, a fiscal measure along with trade liberalization and research and development on total factor productivity for a panel of 153 industrial firms listed on the Pakistan Stock Exchange over the period 1997-2017. For empirical analysis, we employ the system generalized method of moment estimator. In the first step, we estimate industrial production function and the results reveal that raw material, industrial labour force and energy play vital role in enhancing industrial production. Whereas, industrial capital exerts negative impact on industrial output. We also measured total factor productivity using the production elasticities. In the second step, we examine the impact of corporate tax, trade liberalization and research and development on total factor productivity. The results indicate that higher level of corporate tax exerts negative impact on total factor productivity. The findings reveal that higher corporate taxation discourages industrial firms to undertake research and development thereby exerting adverse impact on total factor productivity of firms. The impact of trade liberalization proxied by average tariff is positive while customs duty and sales tax negatively impact firm-level total factor productivity. These findings provide useful insights for managers, investors and policy makers in Pakistan.

This Study investigates evaluation policies for goodwill under the current tax law and suggests improvements as follows. First, even though not appear on the financial statements of acquiree at the date of acquisition, the current corporate tax raw regulates that firms need to estimate purchased goodwill including acquisition amount and additionally recognizable intangible property right with no distinction. According to this rule, purchased goodwill from business combination under the current tax raw has a drawback in overestimating. So, there is need of further improvement on the current related purchased goodwill regime to distinguish additionally recognized intangible property right from purchased goodwill. Second, in the consideration of internally generated goodwill, suggested in the current inheritance and gift tax act as a supplementary evaluation technique, the estimated value of goodwill may contain some bias, since the current regulation uniformly applies to all the companies with no industry characteristics. This may particularly become problematic while computing abnormal earnings, uniformly applying the 10% normal return to all the companies since the normal return is not likely to reflect industry characteristics and thus the computed abnormal earnings may be biased. Therefore, there is need to revise the current regulation relating to the normal return, to convert from the existing 10% rule to the industry average rate of return method.

This paper presents an integrated analysis of supply chain and financing decisions of multi-national corporation. We construct a model in which multiple currency storage units are installed to manage the currency flows associated with multi-national supply chain activities such as raw material procurement, process operation, inventory control, transportation and finished product sales. Core contribution of this study is to quantitatively investigate the influence of macroscopic economic factors such as exchange rates and taxes on operational decisions. The supply chain is modeled by the Process-Storage Network with recycle streams. The objective function of the optimization is minimizing the opportunity costs of annualized capital investments and currency/material inventories minus the benefit to stockholders interpreted by home currency. The major constraints of the optimization are that the material and currency storage units must not be depleted. A production and inventory analysis formulation, the periodic square wave (PSW) model, provides useful expressions for the upper/lower bounds and average levels of the currency and material inventory holdups. The expressions for the Kuhn-Tucker conditions of the optimization problem are reduced to a subproblem and analytical lot sizing equations. The procurement, production, transportation and financial transaction lot sizes can be determined by analytical expressions after the average flow rates are already known. We show that, when corporate income tax is taken into consideration, the optimal production lot and storage sizes are smaller than is the case when such factors are not considered typically by 20 %.
