ABSTRACT

The purpose of this research is to determine Muslim consumers’ purchase perceptions of Halal products in Pakistan. The research team has integrated different factors such as processing, Halal logo, ingredients, health consciousness, perceived value, food safety concern, and religious factor with Theory of Reasoned Action (TRA), and they investigated their influence on consumers’ attitudes and intentions to purchase Halal food products. A survey was conducted in Islamabad and Rawalpindi city, Pakistan. A total of 282 (56.4%) completed questionnaires were received from 500 respondents. Structural equation modeling technique was used to determine consumers’ purchase intention and behavior regarding Halal products. Except for health consciousness and Halal logo, all factors positively influence consumers’ attitude and purchase intention of Halal food products and, subsequently, their purchase behavior.  相似文献

This paper reviews the expanding financial turmoil that has been triggered by the Asian crisis. It examines the factors behind the crisis, its impact on African countries and the main lessons and policy implications for African countries. The onset of the Asian crisis seems to have taken everybody by surprise because the Asian countries that were hit by the crisis had been among the most successful in sustaining high rates of economic growth, keeping high saving and investment rates and improving the quality of life of their citizens. However, the emerging consensus is that the Asian crisis is a hybrid of structural and policy distortions (macro- and micro-economic) in the affected economies. The impact of the crisis on African countries was mainly transmitted through declines in export prices and volumes. The low demand for primary commodities induced by the crisis and the large depreciation of Asian currencies appear to have played major roles in depressing commodity prices. With only a few exceptions, the commodities that suffered large price declines are those for which Asia constitutes an important market (e.g. oil) and/or those mostly supplied by Asian countries (e.g. copper, timber and rubber). Africa’s oil-exporting countries, which experienced large deterioration in their terms of trade, were the most affected. For the continent as a whole, export proceeds declined by 9.5 per cent between 1997 and 1998. This was the product of a 7 per cent decline in export prices and a 2.5 per cent decline in the volume of exports. The paper estimates that the crisis has caused the growth rate in the region to slide down by 1.2 percentage points, which indicates a loss of US $6.2 billion using aggregate GDP for 1997 as the base. To put this in an order of magnitude, it is about US $2 billion higher than the annual average flow of FDI to the continent in recent years. For the majority of African countries where the inflow of private capital is small and where public debt is dominant, the traditional risk management policies, such as adopting realistic exchange rates and reducing government deficits and inflation rates, should continue to be major policy tools to prevent financial crisis. However, as the role of private capital increases the design of macroeconomic policies would need to heed the lessons emerging from Asia. One basic lesson is that careful sequencing of domestic and external liberalization is needed. In that, restrictions on the capital account, especially on the more volatile capital flows should be lifted only after the domestic financial sector has been strengthened with adequate regulatory and supervisory institutions. This is particularly true because the Asian crisis has shown that reserves, even at very high levels, can be quickly depleted given the scale and volatility of short-term capital flows. Le présent document analyse le développement de la tourmente financière déclenchée par la crise asiatique. Il examine les causes de cette crise, son impact sur les pays africains, les principaux enseignements à en tirer et ses incidences politiques pour l’Afrique. Le déclenchement de la crise asiatique semble avoir pris tout le monde de court. Les pays asiatiques touchés sont parmi ceux qui avaient enregistré des taux de croissance économique des plus élevés, maintenu des taux d’épargne et d’investissement des plus soutenus, et amélioré le plus la qualité de vie de leurs citoyens. Cependant, de l’avis général, la crise asiatique résulte de la conjonction de distorsions d’ordre structurels et politiques (macro et micro économiques) dans les pays touchés. Son impact sur les pays africains a été principalement ressenti é; travers la baisse des prix et du volume des exportations. Le fléchissement de la demande des produits de base et la forte dépréciation des monnaies asiatiques provoqués par la crise ont manifestement joué un rôle déterminant dans la chute des cours des produits de base. A quelques exceptions près, les produits dont les prix ont sensiblement baissé sont ceux pour lesquels l’Asie constitue un important marché (par exemple le pétrole) et/ ou ceux qui sont essentiellement fournis par les pays asiatiques (cuivre, bois, caoutchouc). Les pays africains exportateurs de pétrole, qui ont subi une détérioration marquée de leurs termes de l’échange, ont été les plus touchés. Pour l’ensemble du continent, les recettes d’exportation ont baissé de 9,5 pour cent entre 1997 et 1998. Cette situation résulte de la baisse de 7 pour cent des prix et de la contraction de 2,5 pour cent du volume des exportations. Ce document estime que la crise a entraîné un ralentissement de croissance de 1,2 point de pourcentage, soit une perte de 6,2 milliards de dollars EU, si l’on utilise comme base le PIB global de 1997. Traduit en ordre de grandeur, ce chiffre est d’environ 2 milliards de dollars supérieur au montant des flux moyens annuels d’IDE obtenus par le continent au cours de ces dernières années. Pour la majorité des Etats africains oú l’apport de capitaux privés est faible, et la dette publique écrasante, les politiques traditionnelles de gestion de risque, comme l’adoption de taux de change réalistes et la réduction des déficits publics et du taux d’inflation, doivent demeurer les principaux moyens d’action pour prévenir les crises financières. Cependant, à mesure qu’augmente le rôle des capitaux privés, la conception des politiques macroéconomiques devrait tenir compte des leçons qui se dégagent de l’expérience asiatique. La principale leçon est qu’il faut faire preuve de prudence dans la programmation de la libéralisation interne et externe. Dans cet esprit, la restriction des mouvements des capitaux, notamment ceux de capitaux les plus volatiles, ne doit être levée qu’après la consolidation du secteur financier au niveau interne avec le concours d’institutions compétentes de réglementation et de contrôle. Cette précaution est d’autant plus nécessaire que la crise asiatique a démontré que les réserves, même à des niveaux très élevés, peuvent s’épuiser rapidement du fait de l’ampleur et de la volatilité des flux des capitaux à court terme.  相似文献

The paper investigates the effects of corporate ownership concentration on audit fees in emerging economies, using Bangladesh as a case. Prior studies have indicated that audit fees in Bangladesh are significantly low. Also, the Bangladeshi private sector is dominated by high ownership concentration. Agency theory predicts that in an efficient market, managers in a highly concentrated ownership situation will have sufficient incentives to have more rigorous audits performed. However, managers in emerging economies, where the markets are not as strong, may not have similar incentives. We test whether audit fees in Bangladesh are related to corporate ownership concentration. Our results indicate that audit fees have a significant negative relationship with sponsor and institutional ownership concentrations. This indicates that in Bangladesh, companies actually pay lower audit fees when these are dominated by sponsor and institutional shareholders. For the public shareholders, we find a negative, but statistically insignificant relationship. The results seem to suggest that corporate ownership pattern may be a major factor in explaining the low audit fees in Bangladesh.  相似文献

This study investigates long run overreaction and seasonal effects for Malaysian stocks quoted on the Kuala Lumpur Stock Exchange (KLSE), for the period 1986–1996. Stocks exhibiting extreme returns relative to the market over a three year period experience a reversal of fortunes during the following three years. There is also evidence that employing a contrarian trading strategy may yield excess returns. Of particular interest is the apparent existence of a Chinese New Year effect in both the level of market returns, and the overreaction profile for KLSE stocks. These seasonalities mirror the January-effect observed in US markets.  相似文献

Do family firms care more for different stakeholders than nonfamily firms when operating in a hostile business environment? This study addresses this question and fills the existing void in family business research. It shows that family-controlled firms adopt corporate social responsibility strategies and balance the demands of internal and external interest groups to preserve their socio-emotional wealth while facing fierce competition, resource scarcity, and penurious economic conditions. More specifically, our analysis of an international sample of 956 listed firms from 2006 to 2014 reveals that family firms show a higher level of corporate social responsibility (CSR) performance and better stakeholder orientation than nonfamily firms. Our findings are useful for managers, policymakers, and responsible investors.  相似文献

We investigate the association between voluntary formation of board investment committee (IC) and corporate cash holdings of nonfinancial firms over the corporate life cycle stages for a large sample of Gulf Cooperation Council firms during 2005–2016. We find that IC increases corporate cash holdings in growth and maturity stages of firm, compared to introduction, shake‐out, and decline stages. These results have important implications for investors, policy makers, and regulators. Our findings are robust to various econometrics specifications.  相似文献

Aims: Medicare patients with metastatic or surgically unresectable urothelial carcinoma (mUC) often receive platinum-based chemotherapy as first line of therapy (LOT), but invariably progress, requiring additional LOTs and healthcare resource use (HCRU). To better understand the evolving mUC treatment landscape, the economic burden of chemotherapy-based mUC treatments among US Medicare patients was estimated.

Methods: Newly diagnosed Medicare patients with mUC were identified from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Patients were followed from diagnosis to death, disenrollment, or end of study to characterize LOTs (first [LOT1], second [LOT2], and third or greater [LOT3+]). Kaplan-Meier methods were used to estimate overall survival (OS) by LOT. HCRU and mean costs were reported over the follow-up period, LOT duration, and maximum LOT received.

Results: Among 1,873 eligible patients with mUC (median age?=?77?years; median follow-up?=?7.5?months), 1,035 (55%) received no chemotherapy. Among chemotherapy-treated patients, 61% had LOT1 only, 25% had LOT1 and LOT2 only, and 14% had LOT3+. Median OS was 8.1?months, range was 4.3 (untreated) to 29.8 (LOT3+) months. HCRU frequency increased with additional LOTs. Mean cumulative per-patient cost was $82,912 for all patients, increasing with additional LOTs (untreated?=?$57,207; LOT1?=?$99,213; LOT2?=?$125,190; LOT3+?=?$163,884). Mean per patient per month cost was $18,827 for all patients, decreasing with increasing number of LOTs received (untreated?=?$27,211; LOT1?=?$9,601; LOT2?=?$7,325; LOT3+?=?$6,017).

Limitations: Potential for treatment misclassification when using the algorithm defining LOTs and non-generalizability of results to younger patients.

Conclusions: Over 50% of Medicare patients with mUC received no chemotherapy. Among chemotherapy-treated patients, most received only one LOT. Additional LOTs led to higher mean costs and HCRU, but as patients were followed longer, monthly costs decreased. As treatments evolve to include immuno-oncology agents, these findings provide a clinically relevant economic benchmark for mUC treatment across different traditional LOTs.  相似文献

In this paper we apply a new efficient numerical method for valuing default free bonds and contingent claims within the CKLS interest rate model. Using historical parameter estimates of the CKLS model for Australia, Japan, and the United Kingdom we compare implied bond and contingent claim prices. Our results indicate that default free bond prices and contingent claim prices are sensitive to the underlying interest rate model used.  相似文献

This article examines the out‐of‐sample pricing performance and biases of the Heston’s stochastic volatility and modified Black‐Scholes option pricing models in valuing European currency call options written on British pound. The modified Black‐Scholes model with daily‐revised implied volatilities performs as well as the stochastic volatility model in the aggregate sample. Both models provide close and similar correspondence to actual prices for options trading near‐ or at‐the‐money. The prices generated from the stochastic volatility model are subject to fewer and weaker aggregate pricing biases than are the prices from the modified Black‐Scholes model. Thus, the stochastic volatility model may provide improved estimates of the measures of option price sensitivities to key option parameters that may lead to more effective hedging and speculative strategies using currency options. © 2000 John Wiley & Sons, Inc.
