This paper examines the origins, growth, and the development of accounting practices and disclosures in Pakistan and the factors that influenced them. We trace the early days of accounting in the Indian subcontinent and discuss the British colonial influence. We examine the development of accounting in Pakistan through three eras: Independence through 1971, Post 1971-1984, and 1984 to present. We describe how the colonial past and later the international financial institutions such as the Asian Development Bank and the International Monetary Fund played key roles in shaping accounting and reporting practices of the country. Pakistan's adoption of International Financial Reporting Standards as national standards has not led to improvement in the quality of financial reporting. We argue that Pakistan, even though classified as a common law country in literature, exhibits most of the properties of code law countries. We conclude that lack of investor protection (e.g., minority rights protection, insider-trading protection), judicial inefficiencies, and weak enforcement mechanisms are more critical to explaining the state of financial reporting in Pakistan than are cultural factors. This insight has policy implications for developing countries that are making efforts to improve the quality of the financial reporting of their business entities.  相似文献

This paper adopts multilevel analysis to study the agglomeration-performance nexus for domestic firms in sub-Saharan Africa. We show that contextual factors can explain up to 30 % of the variance in firms’ productivity, more than half of which depends on the geographic location. Our results show also that African firms’ productivity is positively correlated to the size of the agglomeration when they locate in larger cities specialized in different sectors, while the relation turns negative when they face direct competition from firms in the same industry. These effects are similar in the services and the manufacturing industries, even if in the latter positive spillovers are found to be conditional to the presence of backward and forward linkages with nearby firms. Finally, we are able to show that these effects are also confirmed when domestic firms locate close to foreign multinationals, especially those coming from the South.  相似文献

Ongoing regulatory reforms have led to several novel spectrum sharing models under the general umbrella of dynamic spectrum sharing. The private commons model introduced by FCC in 2004 allows spectrum licensees to provide secondary access to spectrum on an opportunistic basis while retaining ownership. Since wireless communication systems are typically overprovisioned in order to deliver service-level guarantees to (primary) users under short-term load variations, this model bears significant potential by facilitating utilization of temporal and spatial surplus of capacity through serving secondary users at possibly different service levels. A potential barrier to adoption of the private commons model is the uncertainty about secondary price–demand relationship which is difficult to predict in an emerging market: A selected price for secondary access may be profitable for some values of secondary demand but not for others, leading to a profound uncertainty about ultimate benefit of spectrum sharing. This paper aims to eliminate such an uncertainty by devising concrete guidelines and methods for profitability. The paper establishes that the price of secondary spectrum access can be chosen to guarantee profitability for any value of secondary demand: It is shown that for both the coordinated and uncoordinated commons regimes a profitable price should exceed a threshold value, which can be calculated. Hence profitability of private commons is insensitive to the demand function. This observation has two complementary interpretations: From a business perspective it provides a constructive approach to profitability; and from a regulatory perspective it provides reassurance that private commons is a healthy model. The paper also leverages the insensitivity property and outlines a technique to further enhance revenue via iterative spectrum offerings.  相似文献

The prevailing dollar peg of the Gulf Cooperation Council (GCC) countries and the absence of any significant current and capital account restrictions led some to believe that these countries have lost monetary independence. However, the paper presents evidence that interest rates of the GCC countries did not converge to the interest rates of the US implying that the assets of the GCC countries are not perfect substitutes to the US assets. This imperfect asset substitutability has allowed the GCC countries to manoeuvre their monetary policies and the central banks of the GCC countries have had some control over their money growth rates by sterilising the changes in international reserves. Results indicate that the monetary authorities of these countries used domestic credit policy to attain some domestic policy objective while engaging in sterilised foreign exchange intervention. This result implies that the proposed GCC central bank should be able to maintain the monetary independence as a group and can reap the benefit of monetary efficiency of the proposed Gulf Monetary Union.  相似文献

Abstract

Accident risk analysis for human safety and infrastructural improvement are key requirements of the engineering sector. The purpose of this paper is to identify and prioritize problematic segments of roads based upon the risk evaluation concept and to focus on the severity of accidents regarding human life loss and easy manoeuvring. This study includes the concept of considering road segments as decision-making units for application of data envelopment analysis (DEA) technique which has no compulsion of the distribution function and critical assumptions, unlike the multiple regression models. According to the proposed methodology, a section of Motorway (M-2) Lahore-Islamabad has been analyzed. Out of 200 segments under consideration, 99 segments were selected with at least one accident and one injury or fatality. Furthermore, for risk calculation and ranking of road segments, the DEA technique along with the cross-risk matrix method was applied. This optimization technique could not only be helpful in ranking but also technical decision-making and prioritizations for safety improvement, policymaking and budget allocation.  相似文献

Financial regulations are developed to curb financial and economic fragility costs without undermining the economic contributions of banks to economic development. To understand the impact financial regulations have on reducing the financial fragility of banks we use the probability-of-default of banks as a proxy for bank failure. After analyzing data collected from 15 countries with a dual banking system for the period 2000–2015, we find convincing evidence that not all financial regulations have risk-reducing benefits for banks and the impact of financial regulations on default risk is not the same for conventional banks (CBs) and Islamic banks (IBs). The empirical evidence suggests that regulations that lessen overall default risk have a greater impact on IBs while those increasing default risk have a greater impact on CBs. Based on our findings we recommend that regulators should consider the different natures of CBs and IBs and tailor financial regulations to suit these operationally distinct financial intermediaries.  相似文献
