Earlier studies that investigated the relation between exchange rate and domestic output employed panel data. In this paper we improve upon the traditional approaches of the existing econometric literature on contractionary devaluation or depreciation by applying panel unit root and panel...

Previous research seeking to assess the short-run and long-run effects of currency depreciation on the UK trade balance has employed either aggregate trade data between U.K. and the rest of the world or bilateral trade data between U.K. and one of its major trading partners, the US. Neither...

The J-Curve effect is a concept used to describe the short-run effects of currency depreciation on the trade balance, i.e., an initial deterioration of the trade balance followed by an improvement. A concept close to the J-Curve is the S-Curve introduced by Backus, et al (1994) who found that...

Earlier studies that investigated the impact of devaluation on domestic production relied upon the aggregate demand analysis. They argued that by making a country?s exports cheaper and imports expensive, devaluation is said to stimulate the aggregate demand and thus, domestic production. In this...

A rich literature argues that stock repurchases often serve as positive economic signals beneficial to investors. Yet due to their inherent flexibility, open-market repurchase programs have long been criticized as weak signals lacking commitment. We evaluate whether some managers potentially use...

An important problem for the homeless service sector is understanding the size of homeless populations, which has implications on planning services and social policy. The aim of this study is to apply capture-recapture methods to count the primary homeless population in the Adelaide city council...

The trust of sellers and transactions is a very important issue in e-commerce and e-service environments. At some e-commerce websites (such as eBay1), the trust management mechanism can compute a trust value of a seller, which is based on the ratings of past transactions given by buyers. This...

In this paper, we consider a single-machine common due-window assignment scheduling problem with deteriorating jobs. Jobs’ processing times are defined by function of their starting times and job-dependent deterioration rates that are related to jobs and are not all equal. The objective is to...

We consider the single machine job sequencing problem with release dates. The main purpose of this paper is to investigate efficient and effective approximation algorithms with a bicriteria performance guarantee.
