This paper presents the findings of a comparative study on the performance of the initial public offerings (IPOs) of shares listed on the Hong Kong Stock Exchange (HKX), Singapore Exchange (SGX) and Bursa Malaysia (MYX). One indicator of the success of an IPO is its subscription rate, which can be used as a proxy for the level of investor confidence in the stock being offered. This paper examin...

This paper describes the design and implementation of an Internet Telephone Software System which allows real-time full duplex voice communication between two parties through the Internet. The system consists of two main components: Telephone Exchange and Telephone Software. The Telephone Exchange manages a list of active users who are connected to the system, establishes the telephone connecti...

The unprecedented rise in Foreign Exchange Reserves (FER) in some of the Asian countries raises a concern about their optimal size and appropriate utilization. In India too, in recent months, different ways to utilize FER, in particular, to finance infrastructure, have been debated. The Government of India intends to use a part of its FER for infrastructure financing and has announced a scheme ...

The asymptotic stability of positive fractional switched continuous-time linear systems for any switching is addressed. Simple sufficient conditions for the asymptotic stability of the positive fractional systems are established. It is shown that the positive fractional switched systems are asymptotically stable for any switchings if the sum of entries of every column of the matrices of all sub...

This paper considers the pricing decision faced by a seller of bundles composed of a service and an associated product offered to customers on a subscription basis using a two-part tariff scheme. An optimal pricing policy that maximizes the profit of a firm is obtained using a dynamic programming approach and it is found that, in the long run, there is an optimal number of customers associated ...

This paper investigates firms’ decisions to reimburse consumers’ switching costs in network industries. Prior literature finds that switching costs incentivize firms to harvest their locked-in consumers rather than price aggressively for market dominance, thereby resulting in a lower market concentration. Using a dynamic duopoly model, we show that this result is reversed if firms have the opti...

We investigate a new point in the design space of red/green systems [19, 30], which provide the user with a highly-protected, yet also highly-constrained trusted (“green”) environment for performing security-sensitive transactions, as well as a high-performance, general-purpose environment for all other (non-security-sensitive or “red”) applications. Through the design and implementation of the...

We consider Personal Assistant (PA) agents as cognitive agents capable of helping users handle tasks at their workplace. A PA must communicate with the user using casual language, sub-contract the requested tasks, and present the results in a timely fashion. This leads to fairly complex cognitive agents. However, in addition, such an agent should learn from previous tasks or exchanges, which wi...
