Economic viability of private commons: Framework and guidelines for profitability

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.     

Sterilisation and Monetary Control by the GCC Member Countries

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.     

Does a one-size-fits-all approach to financial regulations alleviate default risk? The case of dual banking systems

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.     

Accounting development in Pakistan

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.     

A Bibliometric Review of the Special Issues of Psychology & Marketing: 1984-2020

Psychology & Marketing (P&M), an internationally reputed journal, publishes original, peer-reviewed, empirical research on the application of psychological theories and techniques to marketing. The aim of this essay is to provide a bibliometric overview of the leading trends in the special issues of P&M over its history (1984–2020). Using bibliometric techniques, we analyze the impact of the special issues via their most cited papers, most productive authors, affiliated institutions and countries, as well as the best guest editors who contributed to the selection of the most cited special issue articles. Using network analysis VOSviewer software, we also group the special issues into four clusters to identify common themes. Further, we develop graphical visualization of coauthorships, bibliographic coupling, and cocitations. Results show that the most productive contributors are from American institutions and that P&M remains well connected to other leading journals in the marketing and psychology discipline, such as the Journal of Marketing Research, the Journal of Personality and Social Psychology, the Journal of Consumer Research, the Journal of Marketing, and the Journal of Business Research.     

Significance of attitudes,passion and cultural factors in driver’s speeding behavior in Oman: application of theory of planned behavior

Abstract

Traffic accidents and related fatalities have become a major public health problem in the world. This study aims to identify the significant factors that play an important role in the speeding behavior of drivers. A comprehensive questionnaire was designed and conducted with the students and employees of the University of Nizwa. The questionnaire items were designed considering the theoretical background of the theory of planned behavior (TPB) and local socio-cultural aspects of the driving environment. A total of 303 usable samples were obtained. The collected data were analyzed using factor analysis and structural equation modelling technique. The extracted factors of speeding passion and culture, speeding attitudes, subjective norms and perceived behavioral control are significant determinants of drivers speeding behavior in Oman. The driver’s speeding attitudes, speeding culture, and passion have positive association with the drivers’ speeding intentions and behavior, and driver’s perceived behavioral control forms negative relationship with the speeding behavior. This study confirms the application of the TPB in predicting the drivers’ speeding behavior in the context of Oman.     

Resolving the Presidential Puzzle

Many financial economists are puzzled by the fact that stock returns are higher under Democratic than Republican presidencies. In this paper, we test whether this return differential is explained by risk using a conditional version of the Fama and French (1993) model that allows risk to vary across political cycles. We find that the presidential puzzle can be explained when risk is properly taken into account. Much of the return differential can be attributed to the fact that Democratic presidencies are associated with higher market and default risk premiums than their Republican counterparts.     

Education bias of trade liberalization and wage inequality in developing countries

The aim of this article is to examine the impact of increased trade on wage inequality in developing countries, and whether a higher human capital stock moderates this effect. We look at the skilled–unskilled wage differential. When better educated societies open up their economies, increased trade is likely to induce less inequality on impact because the supply of skills better matches demand. But greater international exposure also brings about technological diffusion, further raising skilled labour demand. This may raise wage inequality, in contrast to the initial egalitarian level effect of human capital. We attempt to measure these two opposing forces. We also employ a broad set of indicators to measure trade liberalization policies as well as general openness, which is an outcome, and not a policy variable. We further examine what type of education most reduces inequality. Our findings suggest that countries with a higher level of initial human capital do well on the inequality front, but human capital which accrues through the trade liberalization channel has inegalitarian effects. Our results also have implications for the speed at which trade policies are liberalized, the implication being that better educated nations should liberalize faster.     

Takeover Immunity, Takeovers, and the Market for Nonexecutive Directors

We develop and test two competing hypotheses that relate the market for nonexecutive directors to the level of external monitoring mechanism of the firms they serve. The Reward for Discretion Hypothesis posits that directors are valued more when they display discretion concerning their choice of antitakeover provision (ATP) levels rather than follow a rule. Alternatively, the CEO Risk Aversion Hypothesis implies that CEOs seek directors with inclination for uniform and high ATP levels. We examine how changes in ATP levels and approval of value creating/destroying acquisitions affect the careers of nonexecutive directors. Our results, based on data from about 3,000 listed US companies during 1994-2003, support the Reward for Discretion Hypothesis.
