A dynamic model of utility-maximizing agents explains why scarce, durable commodities are typically monetary. The model provides quantitative criteria for distinguishing between monetary and non-monetary durables, and is also used to analyze symmetallic equilibria.The model is then extended to analyze commodity-backed paper money. It is demonstrated that the backing generates trust in the paper money in the dynamic-consistency sense. The model predicts regular devaluations as an equilibrium phenomenon, but finds such behavior to be efficient. Finally, the results are integrated to make a technical point about dynamic models of pure fiat money.  相似文献

In a classical conjoint choice experiment, respondents choose one profile from each choice set that has to be evaluated. However, in real life, the respondent does not always make a choice: often he/she does not prefer any of the options offered. Therefore, including a no-choice option in a choice set makes a conjoint choice experiment more realistic. In the literature, three different models are used to analyze the results of a conjoint choice experiment with a no-choice option: the no-choice multinomial logit model, the extended no-choice multinomial logit model, and the nested no-choice multinomial logit model. We develop optimal designs for the two most appealing of these models using the D-optimality criterion and the modified Fedorov algorithm and compare these optimal designs with a reference design, which is constructed while ignoring the no-choice option, in terms of estimation and prediction accuracy. We conclude that taking into account the no-choice option when designing a no-choice experiment only has a marginal effect on the estimation and prediction accuracy as long as the model used for estimation matches the data-generating model.  相似文献

Information and communication technology (ICT) has a wide ranging impact on business. One of the effects is on the 'make or buy decision'. This is analysed from the perspective of transactzon cost economm (TCE). On the one hand ICT reduces transaction costs by reducing search costs, by facilitating monitoring and control of performance and by yielding a greater flexibility of production, which reduces the transaction specificity of assets. These efiects, favour the decision to 'buy'. On the other hand, ICT reduces economies of scale, in some areas of production, which makes outside production i n a specializedfirm less attractive. Also, ICT may be used to impose switching costs between suppliers and buyers, thereby miszng transaction costs. But such ploys appear to be feasible only temporarily, with a pressure from users and competitors towards standardization and open systems. Thus the effects of ICT are diverse, but on the whole it tends to favour the option to contract out.  相似文献

The impact of multinational firms on the domestic agricultural sector in developing countries is controversial, in particular in India. Relying on a unique set of household‐level data from the state of Punjab, we study the biggest dairy company in the world (Nestlé) in India and compare its vertical spillover effects on upstream suppliers to other market channels (informal sector and cooperatives). We find that farmers that supply informal channels are less efficient and earn lower profits per dairy animal than farmers supplying the cooperative and the multinational sector. Furthermore, we find that farmers using the multinational channel are more efficient than farmers in the cooperative channel, but equally profitable. Hence, we do not find that supplying the cooperative channel is more beneficial for local dairy farmers than supplying the multinational channel. Overall, however, dairy productivity and profitability levels are still dramatically low, with substantial scope for dairy development.  相似文献

Recent contributions to growth theory stress the importance of localized innovation for the performance of more backward countries. In earlier papers, analyses by means of DEA techniques confirmed this intuition. In this paper, we extend this type of analysis by relaxing the macroeconomic viewpoint adopted until now. New databases on output, labor and capital input in the agricultural and manufacturing sectors are developed for 40 countries. Using intertemporal DEA, it is found that changes in the global production frontier are localized at high levels of capital intensity. This result is stronger in agriculture than in manufacturing. Further, a decomposition of labor productivity growth in eight Asian countries for the period 1975–1992 into the effects of capital intensification, learning and innovation is made. The results suggest that there is a particular development path in which increases in capital intensity appear to be a prerequisite to benefit from international technology spillovers.JEL Classification: O14, O30, O40, O47  相似文献

Edward Peter Stringham’s book Private Governance: Creating Order in Economic and Social Life (2015) is a compelling defense of the proposition that private governance is more widely used and more effective than most people think. Stringham looks to history to see how people solved problems of fraud and cheating without government intervention and provides example after compelling example to contradict the strong claim that a government or any third-party enforcer is necessary for voluntary exchange. While Stringham doesn’t take on the tough problem that private governance is not sufficient for its task, his book is intended to be the beginning, not the end, of thinking about private governance.  相似文献

This paper focuses on the organization of new product development in large, R&D‐intensive firms. In these firms, research and development activities are often separated. Research is conducted in dedicated research projects at specialized research labs. Once research results are achieved by research projects, they are transferred to business units for further development and commercialization. We investigate the speed whereby research projects transfer their first research results to business units (hereafter: transfer speed). In particular, we analyze the antecedents and performance implications of transfer speed. Based on data of 503 research projects from a European R&D intensive manufacturing firm, our results suggest that a fast transfer speed (as measured by the time it takes for a research project to develop and transfer its first research result to business units) is associated with a better research performance (as measured by the total number of transfers the research project generates). Moreover, we find that different types of external R&D partners—science‐based and market‐based partners—play distinct roles in speeding up project first research transfers. While market‐based partnerships (i.e., customers and suppliers) generally contribute to a faster transfer of first research results, science‐based partnerships (i.e., universities and research institutions) only speed up first research transfers of technologically very complex projects. Our results also show that early patent filings by research projects accelerate first research transfers.  相似文献
