Effects of interest rate caps on credit access

Journal of Regulatory Economics - We study the liberalization of the microcredit usury rate in Colombia and its effects on loan expansion. In February 2007 the interest rate ceiling for microcredit...     

Adjusting covariance matrix for risk management

The covariance matrix of asset returns can change drastically and generate huge losses in portfolio value under extreme conditions such as market interventions and financial crises. Estimation of the covariance matrix under a chaotic market is often a call to action in risk management. Nowadays, stress testing has become a standard procedure for many financial institutions to estimate the capital requirement for their portfolio holdings under various stress scenarios. A possible stress scenario is to adjust the covariance matrix to mimic the situation under an underlying stress event. It is reasonable that when some covariances are altered, other covariances should vary as well. Recently, Ng et al. proposed a unified approach to determine a proper correlation matrix which reflects the subjective views of correlations. However, this approach requires matrix vectorization and hence it is not computationally efficient for high dimensional matrices. Besides, it only adjusts correlations, but it is well known that high correlations often go together with high standard deviations during a crisis period. To address these limitations, we propose a Bayesian approach to covariance matrix adjustment by incorporating subjective views of covariances. Our approach is computationally efficient and can be applied to high dimensional matrices.     

The age-dependent value of time: a life cycle analysis

A life cycle framework is developed to examine how the value of time (VOT) changes as one ages. We consider two risk-sharing schemes, the Tonti scheme under which wealth is actuarially insured, and the Robinson Crusoe scheme under which insurance institution is entirely absent. For the first time in the literature, we characterize the condition, in terms of key parameters for valuating VOT, under which VOT may increase, decline, or even display more complicated profiles, as one ages. Our analysis reveals the crucial role played by the relative magnitude of the market interest rate to other parameters (including the parameter of time preference, the age-specific mortality and the wage growth rate) in determining the age profile of VOT, and the difference in VOT that is caused by the insurance scheme.      

Triggering the internationalization of Malaysian quantity surveying firms

Although there is an increasing trend of services being traded across borders, quantity surveying (QS) firms in the construction sector remain under-researched. The triggers for the increasing globalization of QS firms are not clear, nor how these triggers are perceived by managers at different levels. A questionnaire was administered in over 84 QS consultancy firms, and the results were analyzed using the repertory grid technique, allowing a comparison between the general respondents and a focus group of senior managers. The findings show that senior managers with significant experience realize the importance of a strong internal capability of the QS firm and the capability to develop innovative offerings, coupled with an awareness of the target market and the ability to secure revenue through key contracts. Firm- and location-specific factors were more important than other competitive advantages or foreign markets’ characteristics when deciding to globalize.     

SMEs and Halal certification

This paper reports on a survey of SMEs and their perception towards Halal certification. Based on 136 SMEs which participated in the study, only 64.9 percent of these SMEs have obtained Halal certification and 44.3 percent of these entrepreneurs are Muslims. A test of association between religion and certification was found to be significant. Although more than 60 percent have ventured internationally, there is no significant association between Halal certification and venturing internationally. Among those that have obtained Halal certification, only 50.7 percent agree that Malaysia has a proper monitoring mechanism on Halal certification compliance and only 38.2 percent of them agree that information on Halal hub in Malaysia is sufficient. This is an implementation gap which needs to be addressed.     

AN ECONOMETRIC ANALYSIS OF THE CANADIAN EGG MARKET

This paper analyzes the market forces - demand, supply, price and trade - operative in the Canadian egg market. Quarterly data for the period 1961–1973 (inclusive) was employed, and Three-Stage least squares procedure was applied to a 12-equation model. Eggs were found to have a very small (–.003) coefficient of direct price elasticity and a negative (–.267) coefficient of income elasticity. At supply level, lagged egg-feed price ratio had an inelastic coefficient. The model was used to forecast for 1974, and was found satisfactory.
Cette étude analyse les forces qui influencent Ie marché des œufs - la demande, l'approvisionnement, les prix et le commerce - au Canada. Les données trimestrielles couvrant la période de 1961 à 1973 (inclusif) fûrent basées sur le système du moindre carré en trois stages sur un modèle à 12 équations. II fut trouvé que les œufs donnent us très petit coefficient (– .003) d'élasticité de prix directe, ainsi qu'un coefficient négatif (–.267) d'élasticité de revenu. Au niveau d'approvisionnement, la proportion ceuf-nourriture retarded avait aussi un coefficient inelastique. Le modéle fut 'employ' pour les predictions de 1974, et fut trouvé satisfaisant.     

FDI and Industrial Restructuring in Post‐WTO Greater PRD: Implications on Regional Growth in China

This paper aims at studying the investment flows in the Greater Pearl River Delta region (Hong Kong‐PRD) in China and its impacts on industrial restructuring at the firm‐level using a business survey with the Hong Kong‐PRD entity acted as a core‐periphery economy. The critical effects of gravity distance on transaction costs in the determination of investment flows are examined statistically by a gravity model by incorporating a hypothetical infrastructural construction project. Survey findings show that the evolution of the cross‐border operations at the main core has directed the outward FDI flows and the subsequent industrial structural adjustments of the core‐periphery economy. This paper has presented a typical illustrative case for further studies of investment flows and its impacts upon industrial adjustments and performance in other regions in China especially after the WTO accession. Its implication on regional economic growth is also discussed.
