Backward integration and collusion in a duopoly model with asymmetric costs

This paper formalizes the idea that input transactions might be used to implement side payments among colluding firms. A model is proposed to analyze the effect of backward integration on collusive outcomes in a downstream duopoly with asymmetric marginal costs. Vertical integration expands the set of collusive outcomes that are sustainable for a given realization of the discount factor. This is an additional effect of vertical integration that antitrust authorities should consider. Side payments implemented by input sales are more relevant the larger the difference in marginal costs, since they allow for the shifting of production towards the relatively more efficient firms, while maintaining firms’ incentives to collude. A price of the input above that posted by an alternative source or sales of the input below cost may be observed, depending on the realization of downstream firms’ costs.      

城乡一体化的理论渊源及其嬗变轨迹考察

运用历史分析法,以时间为经,以理论为纬,对城乡一体化的理论渊源及其嬗变轨迹进行了系统考察。结果表明:有关城乡联系的早期论述是城乡一体化的理论渊源,马克思恩格斯的城乡融合思想将其推向了一个新的高度,而由二元结构理论衍生的城乡偏向发展观却使城乡联系理论难以为继,可它又在一定程度上为其回归奠定了坚实基础,并使之更加深入发展,从而促成了今天关于城乡一体化的热烈探讨。最后,基于当前中国城乡关系的复杂性和特殊性,从理论和实践两个方面指出城乡一体化理论研究对推进中国城乡一体化进程的启示意义。     

Is Country Diversification better than Industry Diversification?

In this paper, we develop a framework in which one can examine the source of industry and country diversification by examining their underlying return components. We find that the global cash flow factor explains on average 39% of the variation of country cash flows and global discount rates explain 55% of the variation of country discount rates. These are much less than the explanatory power of the two factors over industry cash flow and discount rate variations, which are 72% and 78% respectively. This suggests that global factors are much less important for return components at country level than at the industry level. As a result, both better diversification of expected returns and cash flows across countries determine the larger benefits of country diversification versus industry diversification. Moreover, emerging markets tend to have much smaller co‐movements of both dividends and expected returns with those of the world, suggesting a lower degree of integration with the world goods and financial markets. Our results cast doubt on the prevailing wisdom that country diversification should be replaced by industry diversification.     

Long memory and fractional integration in the housing price series of London and Paris

This article deals with the analysis of house price indexes from a long-range dependence viewpoint. In particular, it estimates the fractional differencing parameter in the London and Paris house price series recognizing in some cases the potential seasonality and allowing for breaks in the data. Moreover, it analyses the stability of the parameters across the sample period examined. It is concluded that the series are nonstationary but mean reverting in some cases and very persistent in others. Policy implications are derived.     

Banking integration in ASEAN-6: An empirical investigation

Banking integration is widely considered as the last stepping stone of economic integration, especially at the regional level. This paper aims to introduce extended measures of banking openness and the overall balanced degree of integration through capital flows. Using the quarterly data from the ASEAN-6 economies (Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) from 1996Q4 to 2016Q4, the obtained empirical results reveal that: (i) the degree of banking openness, which measures the total inflows and outflows divided by the total banking assets of the given country, remains low and even slightly decreases, despite the increasing cross-border banking and greater economic links among ASEAN-6; (ii) the overall degree of balance, which calculates the balance and the diversification of outward and inward integration, fluctuates over time but reaches the well-balanced level. Furthermore, the research highlights main drivers of the banking integration in this region, such as regulatory quality, bank size and the global credit risk. These findings have important policy implications for banking stability and integration in ASEAN-6.
