CONVERTIBLE BOND PRICING MODELS

Convertible bonds are an important segment of the corporate bond market, with worldwide outstandings approaching US$235 billion. Simple pricing models value a convertible bond as being equivalent to a straight bond with an embedded option that enables the bond holder to convert to a specific amount of common stock. The straight bond is subject to both interest rate and credit risk, whereas the option to convert is dependent on the underlying stock price, which exposes the convertible bond holder to equity risk. The complexity of these features means that convertible bonds tend to be treated casually in major derivatives and corporate finance textbooks. This paper presents a survey of the theoretical and empirical aspects of convertible bond pricing. The limitations of these studies are highlighted to identify those areas of research that may improve the valuation process and facilitate the application of these securities for corporate financing.     

Changing Perceptions of Maturity Mismatch in the U.S. Banking System: Evidence from Equity Markets

We use the sensitivity of bank holding company equity returns to market interest rates as an indicator of perceived maturity mismatch. Based on data from 1990 to 2009, there is only weak evidence that market participants perceived banks to be effectively short‐funded. However, looking at 1990–1996 and 1997–2009 subsamples separately, our results suggest that U.S. commercial banks were perceived as short‐funded during the earlier time period but not the later. During this time of changing perceptions of maturity mismatch, banks were increasing their holdings of real estate loans as a share of total assets. We present evidence that, subsequent to 1996, market participants perceived real estate loans as having become effectively shorter‐term.     

Proving regularity of the minimal probability of ruin via a game of stopping and control

We reveal an interesting convex duality relationship between two problems: (a) minimizing the probability of lifetime ruin when the rate of consumption is stochastic and the individual can invest in a Black–Scholes financial market; (b) a controller-and-stopper problem, in which the controller controls the drift and volatility of a process in order to maximize a running reward based on that process, and the stopper chooses the time to stop the running reward and pays the controller a final amount at that time. Our primary goal is to show that the minimal probability of ruin, whose stochastic representation does not have a classical form as does the utility maximization problem (i.e., the objective’s dependence on the initial values of the state variables is implicit), is the unique classical solution of its Hamilton–Jacobi–Bellman (HJB) equation, which is a non-linear boundary-value problem. We establish our goal by exploiting the convex duality relationship between (a) and (b).     

International deflation risks under alternative macroeconomic policies

We use a version of the Global Projection Model covering the United States, Euro area and Japan to assess options for dealing with the looming risk of international deflation. The zero floor to interest rates constrains monetary policy. Confidence intervals, derived from stochastic simulations, indicate ranges of uncertainty. The results suggest a high probability of a declining price level for a couple of quarters in 2009. Suitable policy adaptations reduce the risk that this might turn into a prolonged, global deflation. These include: a price level path target for monetary policy, which would respond to previous, as well as expected, shortfalls from the desired inflation rate; a more stimulative fiscal policy; and an increase in the long-run target for inflation.     

From plan to market: financial statements and economic transition in the East German enterprise

This article examines the changing role of financial accounting in the former East Germany as that country underwent the transition from a centrally planned to a market-driven economy. The German government's insistence on a sales model of privatization in preference to some form of mass privatization, combined with legal requirements to make up equity shortfalls in eastern German enterprises, resulted in a highly centralized and interventionist approach to accounting change. The article reviews and analyses the historical, technical, economic and political aspects of this change process.     

Is there a case for replacing parking charges by road user charges?

The price of parking is often considered an important tool with which to influence transport choice but, since many local authorities have limited control over off-street charges and since parking charges have no direct impact on through traffic, its influence on overall travel demand may be limited. Road user charges, on the other hand, do appear to offer an effective means of influencing overall demand. The problem is that public acceptance of such charges is low unless some obvious “carrot” can be identified. This paper explores the possibility that the removal of parking charges might be that “carrot”. Our analysis suggests that, although the removal of parking charges would reduce revenues and dilute the reduction in demand caused by the introduction of road charges, the combined effect might, in certain circumstances, be more beneficial to the local economy and might still yield a net increase in revenue. Given the incidence of impacts, it also appears that a combined scheme would be more equitable and might stand a greater chance of achieving public acceptance than a more conventional road charging scheme. The paper identifies the circumstances in which a combined scheme might work well and outlines the detailed analysis that would be necessary to confirm this.     

A theoretical framework for the studio as a learning environment

In this article we describe a holistic, ecological framework that takes into account the surface structures and pedagogical approaches in the studio and how these elements are connected to the construction of design knowledge: epistemology. In our development of this framework, we came to understand how disciplinary underpinnings and academic culture shape the ways that studio is enacted. Using practice theory, we illustrate our framework with two examples—one in Industrial Design and another in Human Computer Interaction—that demonstrate the ways in which the studio can act as a bridge between academic and professional communities. We came to see the studio as a unique practice community that connects academic and professional contexts. We argue that successful implementation of studio-based learning involves an awareness of disciplinary canons, ontological approaches to knowledge, and the academic constraints on studio-based approaches to learning.
