Enforcement mechanisms for SEC reporting deadlines

SEC filing deadlines accelerated for many firms over the past decade; nevertheless, the percentage of late 10-K filings has decreased by historical standards. From 2000 to 2007, six percent of 10-Ks are late but remain SEC compliant (via a Form 12b-25 filing). An additional 2.5 percent of all 10-K filings are both late and non-compliant. When analyzing all 10-K filings (i.e., both timely and late filings), we find that (1) relatively large stock exchanges, (2) greater analyst coverage, and (3) larger audit firms are each associated with improved timeliness and compliance in 10-K report filings.     

State intervention for food price stabilisation in Africa: Can it work?

Although its arguments may have more general applicability, this paper discusses the desirability and options for the stabilisation of staple food prices principally in Eastern and Southern Africa. It addresses three broad questions: (i) why is stabilisation of food (grain) prices desirable? (ii) what is technically feasible? and (iii) can the governance and trade issues thrown up by suggested mechanisms be solved? It considers a number of options for price stabilisation, assessing the strengths and weaknesses of each and suggesting situations in which each may be appropriate.     

Reason, Rationality, and Fiduciary Duty

This paper argues that since the last decades of the twentieth century the discipline of modern finance has directed fiduciaries to act "rationally"—that is, in the sole financial interest of their funds--downplaying the effects of their investments on others. This approach has deemphasized a previous, more "reasonable" interpretation of fiduciary duty that drew on a conception of prudence characterized by wisdom, discretion and intelligence—one that accounts to a greater degree for the relationship between one's investments and their effects on others in the world. The reasonable approach allows fiduciaries to a greater degree to assess the objective well-being of beneficiaries, to recognize fundamental sources of investment reward in the economy, and to fulfill their obligations to allocate benefits impartially between current and future generations. Reason and rationality can work in a complementary fashion to make investment long-term in its perspective and beneficial to society and the economy as well as to specific funds or portfolios. Determining how to accomplish this challenging task is part of the obligation of fiduciaries as they seek to realize the full potential of the investment assets entrusted to their care.     

PRICE-LEVEL TARGETING AND STABILISATION POLICY: A SURVEY

Abstract.  This paper surveys recent articles on the costs and benefits of price-level targeting, focusing its use as a tool for stabilisation policy. It discusses how price-level targeting can affect the short-run trade-off between output and inflation variability by influencing inflation expectations. It reviews how assigning an explicit price-level target to a central bank that is unable to commit to its future policies can improve economic performance. It surveys other potential benefits and costs. Among the costs, it underlines the importance of perfectly rational expectations for the optimality of price-level targeting, and an exacerbation of the time inconsistency problem.

Ubiquitous interactive visualization of 3D mantle convection using a web-portal with Java and Ajax framework

We have developed a new strategy and espouse a novel paradigm for large-scale computing and real-time interactive visualization. This philosophy calls for intense interactive sessions for a couple of hours at a time at the expense of storing data on many disk drives during regular or heroic runs on massively parallel systems. We have already carried out successfully real-time volume-rendering visualization by employing hundreds of processors for a grid with over 25 million unknowns. Both Cartesian and spherical 3D mantle convection are visualized. The volume-rendered images are viewed on a large display device, with many panels holding around 13 million pixels. We will employ a software strategy involving an hierarchical rendering service, which will have as software an Ajax interface for interactive visualization of large data sets on many different platforms from desktop PC’s to hand-held devices, such as the OQO and the Nokia N-800. An option for stereo viewing is also implemented. We have installed a user interface as web application, using Java and Ajax framework in order to achieve over the Internet reasonable accessibility to our ongoing runs. Our goal is to expand the array of interactive devices, which will make it feasible to carry out ubiquitous visualization and monitoring of large-scale simulations or onsite events and to allow for collaborations across oceans.
