We estimate the disaggregate import demand functions for three basic classes of goods as defined in the System of National Accounts (SNA): capital goods, intermediate inputs, and final consumption goods, and use the findings to shed light on the effects of China's economic growth on its current account. The results showed that as China switches from exports to domestic demand as a key driver for economic growth, China's trade surplus would be expected to shrink rather quickly.  相似文献

With the dramatic increase in federal and state environmental regulation in the 1970s, the cost of compliance also rose. While compliance costs have been discussed elsewhere, the implications for the competitiveness of markets have been evaluated using case studies of specific law changes and specific industries. This study examines the role of environmental regulations as barriers to entry using a panel of industries over ten years. The results indicate that environmental costs increase the value of q for the top quartile of firms, which suggests that compliance cost constitutes a barrier to entry and creates rents for larger existing firms.  相似文献

The returns management process is gaining increasing importance both in academia and among supply chain professionals, not only as a tool in the practice of sustainability, but also for its strategic role in many economic sectors. Several studies show how efficiently returns management can reduce costs and provide a competitive advantage to companies. Likewise, electronic commerce, or e-commerce, has shown significant growth in many countries and, due to its very nature, it presents much higher return rates than traditional trade. However, despite the importance of returns management operation for electronic commerce, few studies explore this theme in the literature. The aim of this paper is to describe the process of returns management of the largest online retailer of the Brazilian market, showing its evolution and analysing its performance, as well as identifying its main shortcomings. We conclude with suggestions for improvements and the implementation of a more efficient system.  相似文献

In this study, the sustainability of the Bretton Woods system from the standpoint of purchasing power parity is discussed. The paper uses wholesale price indexes of the group of seven industrialized countries (G‐7) and examines when persistent price disparities among the countries occurred by applying the panel unit root tests. It is found that the price indexes of G‐7 countries began to diverge in the first half of the 1960s. Evidence from international price differences suggests that the price indexes may have signaled the breakdown of the Bretton Woods system before the inflation rate in the USA accelerated.  相似文献

This study focuses on the relationship between age structure and trade openness. We hypothesise that a higher share of the working‐age population in the total population increases trade openness, because the dependent population tends to spend more than the working‐age population on non‐tradable goods such as education and medical services. We estimate the effects of age structure on trade openness using panel data for 85 countries from 1991 to 2010. The empirical results show that the share of the working‐age population has a positive effect on trade openness. An increase in the share of the working‐age population is considered to be one factor that contributed to an increase in trade openness in the sample period.  相似文献

Eichberger et al. (2007)  characterize the full Bayesian update rule for capacities. This paper shows that a conditional preference relation represented by the Choquet expected utility with respect to the updated capacity through the rule does not satisfy the axiom of Conditional Certainty Equivalence Consistency. A counterexample is provided and it is proved that a relaxation of the axiom maintains their results.  相似文献

A barrier option is one of the most popular exotic options which is designedto give a protection against unexpected wild fluctuation of stock prices.Protection is given to both the writer and holder of such an option.Kunitomo and Ikeda (1992) analytically obtained a pricing formula forexponential double barrier knockout options. Since the logarithm of theirproposed barriers for the stock price process S(t), whichisassumed to be geometric Brownian motion, are nothing but straight lineboundaries, the protection provided by them is not uniform over time. Toremedy this problem, we propose square root curved boundaries±btfor the underlying Brownian motion process W(t). Since thestandarddeviation of Brownian motion is proportional to t, theseboundaries(after transformation) can be made to provide more uniform protectionthroughout the life time of the option. We will apply asymptoticexpansions of certain conditional probabilities obtained by Morimoto (1999)to approximate pricing formulae for exponential square root double barrierknockout European call options. These formulae allow us to computenumerical values in a very short time (t < 10–6sec), whereas it takesmuch longer to perform Monte Carlo simulations to determine optionpremiums.  相似文献

This study considers the macroeconomic effects of retailer market concentration and buyer‐size discounts on inflation dynamics. During Japan's “lost decades”, large retailers enhanced their market power, thus increasing the exploitation of buyer‐size discounts in the procurement of goods. We incorporate this effect into an otherwise standard New Keynesian model. Calibrating to the Japanese economy during the lost decades, we find that these developments led to a deflation of approximately 0.1% annually.  相似文献
