Comparative statics in the multiple-partners assignment game

Malaysia is contemplating removal of most of her subsidy support measures including subsidies on cooking oil which is largely palm oil based. This paper aims to examine the effects of cooking oil subsidy removals on the competitiveness of the oil palm subsector and related markets. This is done by developing and applying a comparative static, multi-commodity, partial equilibrium model with multi-stages of production function for the Malaysian perennial crops subsector which explicitly links different stages of production, primary and intermediate input markets, trade, and policy linkages. Results partly suggest that export of cooking oil will increase by 0.2 per cent due to a 10 per cent cooking oil subsidy reduction, while domestic output of cooking oil may eventually see a net decline of 1.97 per cent. The results clearly point out that the effect of reducing cooking oil subsidies is relatively small at the upstream levels and therefore it only induces minute effects on factor markets. Consequently, the market for other agricultural crops is projected to change very marginally. Keywords: Multicomodity, comparative statics, partial equilibrium model, output supply-factor markets linkages, effects of cooking oil subsidy removals.

Sexual Sensation Seeking

Background: STIs, principally HIV/AIDS, are public health problems that are transmitted by sexual risk behaviours, which have been associated with the sexual sensation seeking (an specific personality factor). In South American context, there are no measurement instruments with psychometric evidence for their use and, in other contexts, only the Sexual sensation seeking scale (Kalichman et al., 1994) is available, which is outdated in content and validity evidence. The purpose of this work is development a scale, in accordance with contemporary psychometric standards, to assess sexual sensation seeking for South Americans young people and adults. Method: instrumental study, with time-space sampling (n=813) of undergraduate students from the two Chilean cities with the highest rates of HIV. Results: Final scale have 8 items to assess two dimensions: 1) sexual emotions seeking; and 2) tendency to sexual boredom. The identified structure provides adequate levels of reliability (ω> .8; α> .7), presents validity evidence, based on the internal structure of the test, using CFA and ESEM (CFI> .95, TLI> .95, RMSEA <. 06), and based on the convergence with other measures (sexual activity with multiple partners, inadequate or insufficient use of protective barriers and sexual activity under the influence of alcohol or drugs). Conclusions: The Multidimensional Scale of Sexual Sensation Seeking evidence adequate psychometric properties to evaluate the search for sexual sensations in equivalents samples.

The present paper is a contribution to the building blocks of an investmentmodel within the framework of an integrated macroeconomic model of anIslamic economy. Investment behavior in the model is guided by an Islamicethicalvalue system and profit-sharing financial contracts. The typical firm’sinvestment decision is believed to emerge from a dynamic inter-temporalmaximization exercise within an infinite time horizon. The method of Calculusof Variations is applied to arrive at the optimal investment and employmentcriteria for the firm. The result is then incorporated into a macroeconomicmodel to study the behavior of key endogenous variables like national incomeand the rate of profit-share. Comparative statics exercised within a generalequilibrium framework reveal the potency of monetary policy but the neutralityof fiscal policy with respect to output and employment.IntroductionThe past decade has witnessed a tremendous outpouring of interest aswell as effort in the formalization of economic models based on profit-sharingfinancial arrangements as an Islamic alternative to the conventional interestbasedeconomic system. Several macroeconomic models for interest-freeeconomies have been proposed (Anwar 1987; Habibi 1987; Metwally 1981& 1983). The rigor of an integrated approach to such macroeconomic modelhgdepends on the rigor of the component models, namely, the consumption,investment, monetary, and fiscal relationships. Economists have writtenextensively on different aspects of consumer behavior in Islamic societies.Kahf (1978) and Khan (1984), among others, have contributed to the conceptualand analytical formulation of the consumption function under ...
