Sediment flux from Lesser Zab River in Dokan Reservoir: Implications for the sustainability of long‐term water resources in Iraq

Prudent management of Iraqi water resources under climate change conditions requires plans to be based on actual figures of the storage capacity of existing reservoirs. With the absence of sediment flushing measures, the actual storage capacity of Dokan Reservoir (operated since 1959) has been affected by the amount of sediment delivered during its operational life leading to an undetermined reduction in its storage capacity. In consequence, there has not been an update on the dam's operational storage capacity curves. In this research, new operational curves were established for the reservoir based on a recent bathymetric survey undertaken in 2014. The reduction in reservoir capacity during the period between 1959 and 2014 was calculated by the mean of the difference between the designed storage capacity and the storage capacity which was concluded from the 2014 bathymetric survey. Moreover, the rate of sediment transported to the reservoir was calculated based on the overall quantities of accumulated sediment and the water discharge of the Lesser Zab River into the reservoir. The results indicate that the dam capacity is reduced by 25% due to sedimentation of an estimated volume of 367 million cubic metres at water level 480 m.a.s.l. The annual sedimentation rate was about 6.6 million cubic metres, and the sediment yield was estimated to be 701.2 t?km^?3?year.     

Evidence on the efficacy of interest-rate risk disclosures by commercial banks

This paper documents evidence on the efficacy of maturity-gap disclosures of commercial banks in indicating their net interest income that is exposed to interest-rate risk. For the large sample of banks that filed call reports from 1990 to 1997, a period that includes a wide range of interest rate movements, we find that (i) one-year maturity gap measures are significantly related to the one-year- and three-years-ahead change in net interest income, (ii) fixed-rate and variable-rate instruments differ in explanatory ability, and (iii) the one-to-five-year aggregate gap measures also have some power in explaining three-year-ahead changes in net interest income. These findings hold after controlling for the ex post growth in assets as well as the amount of rate-sensitive assets and liabilities (a competing set of explanatory variables). Because the Securities and Exchange Commission (SEC)'s [Securities and Exchange Commission (SEC), (1997). Disclosure of accounting policies for derivative financial instruments and derivative commodity instruments and disclosure of qualitative and quantitative information about market risk inherent in derivative financial instruments, other financial instruments, and derivative commodity instruments. Release Nos. 33-7386; 3438223; IC-22487; FR-48; International Series No. 1047; File No. S7-35-95 (January 31, 1997), Washington, DC] tabular disclosures are finer than maturity-gap data, our findings mitigate concerns about the usefulness of the SEC's market-risk-disclosure requirements. Furthermore, they suggest contrary to the claims of certain banks that the omission of prepayment and early withdrawal risk from gap measures does not totally compromise the ability of gap data to indicate interest-risk exposures.     

FTPL-Perspective on Tradable Deficit Permits in the EMU

The Growth and Stability Pact restricts member states in their fiscal policy but also causes inflexibility in the pursuit of wide-ranging economic and social reforms. Tradable deficit permits allow more flexibility for individual member states and provide a stick for those who exceed the deficit limit but also a carrot to those who stay below it. But does the trade in deficit permits affect the monetary objectives of the European Central Bank (ECB)? We argue that from a perspective of fiscal theory of the price level, trade in deficit permits can lead to higher inflation depending on the growth rate and the debt/GDP ratio of the member states.     

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.     

Déjà Vu: The Effect of Executives and Directors with Prior Banking Crisis Experience on Bank Outcomes around the Global Financial Crisis

We investigate the effect of executives and directors with prior banking crisis experience on bank outcomes around the global financial crisis (GFC). Executives and directors with previous experience leading banks through a bank crisis may have been uniquely able to understand the risks, recognize the warnings signs early, and thus respond more effectively to the GFC. Controlling for other executive, director, and bank‐level characteristics, we examine whether bank performance, risk taking, and accounting quality in the period immediately before and during the GFC are affected by having executives or directors who previously served as bank executives or directors during the 1980s/1990s banking crisis (80s/90s crisis). Overall, we find that banks led by these crisis‐experienced executives and directors exhibit stronger performance, lower risk taking, and higher accounting quality in the period around the GFC. These effects are strongest among bank leaders for whom the 80s/90s crisis was most salient. Results are robust to propensity‐matched samples and other analyses performed to rule out alternative explanations. Our results suggest these individuals were able to learn from prior crisis experience.     

Historical path of traditional and modern idea of ‘conscious universe’

What this study shows is that although the ‘idea of conscious universe’ is given further advance by some discoveries of modern sciences, it was articulated by many ancient and previous thinkers. Philosophically, the idea of ‘Consciousness’ can be traced back to ancient times and can be proven through historical documents in various traditions, cultures and religions. In this study, the ideas are provided from perspectives of West, East and Islam. Simply, the term ‘awareness’ and the concept of ‘ability to be aware of the environment’ imply the notion of ‘Consciousness’ in linguistic and psychology. In a comparative study, we show that philosophical and scientific views in the past and contemporary period highly recommended the existence of ‘Consciousness’ attribute. In fact, all of the mentioned studies are talking about the same ideology based on the qualitative perceptions. However, there are some differences in parts, but the major theme is same.     

Does insurance‐growth nexus hold for Malaysia?

The study investigates the impact of insurance activities on economic growth in Malaysia over the period 1990–2015. Combined cointegration in the presence of identified structural breaks was used to confirm the existence of long‐run relationships among economic growth, insurance activities, human capital, physical capital, and industrial production. The findings indicate feedback effects between insurance activities and economic growth in the long run. The study provides new insights for policymaking to enhance economic growth via insurance activities.     

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.     

Reforming the Urban Water Supply and Sanitation (UWSS) Sector in Yemen

In the early 1990s, Yemen suffered from low service coverage and national tariffs that were too low to cover public expenditure, as well as an inadequate level of service provided by the centralized National Water and Sanitation Authority. In 1996, a reform study recommended that the UWSS sector should embrace a policy of decentralization, corporatization, commercialization, the separation of service delivery and regulatory functions, as well as public-private partnerships. The government approved this reform agenda as a Council of Ministers Decree in 1997. Awareness campaigns and consensus-building among stakeholders and political leaders and local demand supported the reform process. Currently, 95% of the total urban population related to utility towns is attended by independent utilities.     

How costly is the Sarbanes Oxley Act? Evidence on the effects of the Act on corporate profitability

The Sarbanes-Oxley Act (SOX) was intended to protect investors by improving the accuracy and reliability of corporate disclosures. However, critics have argued that the costs of SOX far outweigh its intended benefits. Prior studies based on stock-price reactions to SOX-related events document mixed evidence on the expected impact of SOX. In contrast, we provide evidence on the net realized costs of SOX by examining its impact on operating profitability. We find that average cash flows decline by 1.3% of total assets after SOX. These costs are more significant for smaller firms, for more complex firms, and for firms with lower-growth opportunities. Annually, these costs range from $6 million for smaller firms to $39 million for larger firms. Further, we document that net SOX-related costs are not limited to one-time expenses associated with internal-control design and implementation. In aggregate, for the 1428 firms in our sample, these costs amount to about $19 billion per year. Profitability is lower for up to four years post-SOX. To our knowledge, ours are the first estimates of the realized net costs imposed by SOX.
