This paper presents a neoclassical growth model comprising education and child labor with a focus on developing and aid-receiving countries to demonstrate cyclical growth and bifurcation in economic development. The appearance of multiple equilibria has often been attributed to the internal affairs of recipient countries, such as technology in production, subsistence minimum in consumption, and liquidity constraints in investment. The main argument of this paper is that the aid allocation policy employed by donor countries, thereby the motive of aid-providers, leads to divaricated and cyclical development in the recipient countries. 相似文献

We formally analyze the pattern and volume of trade by embedding quasilinear preferences in the standard perfectly competitive, two‐factor, two‐good, two‐country trade model. Quasilinear preferences deliver a natural partition of the two goods into a luxury and a necessity, and preserve the validity of the Heckscher–Ohlin and Heckscher–Ohlin–Vanek theorems. In addition, the predicted factor content of trade under quasilinear preferences is smaller (larger) than the predicted factor content of trade under homothetic preferences if and only if the luxury good is capital (labor) intensive. This result offers a novel explanation for the “missing‐trade” mystery. 相似文献

Abstract. The effects of change in the market (inverse) demand function are systematically analysed for Cournot oligopoly without product differentiation. The general comparative-static results are stated using the original data on firms' cost functions and inverse demand function. Three special models are examined in light of our results. The stability condition is shown to be insufficient for determinate comparative statics. 相似文献

We study how the quality of hospital management and medical care both affect efficiency in Japanese local public hospitals. The efficiency is estimated by a stochastic frontier analysis (SFA) and is regressed against the quality scores in hospital accreditation by the Japan Council for Quality Health Care (JCQHC). We find that rule-based hospital management relates to high efficiency, while the suitable management of beds and supplies relates to low efficiency. 相似文献

While it is generally accepted that Information Technology (IT) has a self-propagating function which ensures that the more widespread its use, the greater its functionality, its emerging dynamism remains a black box.This paper attempts to shed some light on this dynamism through utilizing monthly trend data for the number of Japan's mobile phone subscribers over the last 12 years. A bi-logistic growth model demonstrating the diffusion trajectory initiated by both generations of mobile phones was constructed, with the goal of identifying the increase in the functionality development in the transition from traditional mobile phones with a simple communication function (1st wave mobile phone) to mobile phones with an Internet protocol function (2nd wave mobile phone).Through an empirical analysis utilizing the bi-logistic growth model, it was determined that the 2nd wave mobile phone emerged at an earlier stage of diffusion trajectory than the 1st stage mobile phone, which enabled a sustainable functionality development in Japan's mobile phones over the decade.Factors governing a dramatic decrease in mobile phones prices were analyzed, utilizing the result of the measurement of functionality development. This led to the discovery that while an increase in functionality development enhanced the price of mobile phones, this increase accelerated self-propagating diffusion, thereby enabling a dramatic reduction in prices through the effects of learning exercise and economies of scale.Based on the foregoing findings, the driving forces of self-propagating functionality development were analyzed, and it was determined that effective utilization of potential resources in innovation (e.g., assimilation of spillover technology and learning effects) is the key driving forces behind self-propagating functionality development. 相似文献

This paper uses a dynamic general equilibrium model with money to investigate theoretically under what conditions deflation impinges on a government's fiscal standing. Focus is placed on an upper bound that is compatible with a no Ponzie game condition for the government and an equilibrium. A comparative dynamics analysis demonstrates that if a government's fiscal deficit is not so high, deflation has a negative impact on the upper bound, while if a government's fiscal deficit exceeds a critical level, deflation rather improves it. The critical level depends on a time stream of disposable real incomes and a preference parameter. 相似文献

Many industries are made up of a few big firms, which are able to manipulate the market outcome, and of a host of small businesses, each of which has a negligible impact on the market. We provide a general equilibrium framework that encapsulates both market structures. Due to the higher toughness of competition, the entry of big firms leads them to sell more through a market expansion effect generated by the shrinking of the monopolistically competitive fringe. Furthermore, social welfare increases with the number of big firms because the procompetitive effect associated with entry dominates the resulting decrease in product diversity. 相似文献
