Estimates of the steady state growth rates for selected Asian countries with an extended Solow model

This paper develops an extended version of the Solow (1956) growth model in which total factor productivity is assumed a function of two important externalities viz., learning by doing and openness to trade. Using this framework we show that these externalities have played an important role to improve the long run growth rates of six Asian countries viz., Singapore, Malaysia, Thailand, Hong Kong, Korea and the Philippines. A few broad policies to improve the long run growth rates of these countries are suggested.     

我国基本养老保险基金收支失衡的原因及对策

当前,我国基本养老保险基金存在严重的收支不平衡问题,其原因：一是基本养老保险基金覆盖面窄,基金征缴率低,缴费工资基数小;二是政府尚未承担制度转轨债务的责任,使得养老保险基金严重缺乏补充基金;三是制度外支出的随意扩大,严重增加了养老保险基金的负担。解决这个问题的主要对策：首先,要扩大养老保险覆盖面,提高征缴率,严格核实缴费工资基数,扩大基本养老保险基金的收入来源;其次,要逐步延长退休年龄,严禁提前退休,开源节流,缓解基本养老保险基金收支失衡的矛盾;再次,要明确国家对“老人”、“中人”养老金权益中相当于“个人账户”金额的偿还责任,加大政府投入,弥补养老保险基金的不足。     

美国金融监管体系改革的启示与借鉴

在本轮全球金融危机的演进过程中,金融监管制度性缺陷、监管漏洞和监管效率低下等是危机深化的重要因素;在危机的救援和金融体系的改革中,加强金融监管体系改革成为英美等国的重大政策举措.为了防范风险,夯实应对金融危机的体制和政策基础,中国应该着力加强和改进金融监管,努力维护金融体系的稳健与安全,促进金融经济与实体经济的有效融合,进而保障金融安全和经济平稳较快发展.     

绿色并购有助于重污染企业塑造绿色形象吗？

以2008—2021年我国A股重污染行业上市公司并购事件为研究对象,实证检验绿色并购对企业绿色形象的塑造作用、影响机制和作用场域。研究发现：绿色并购显著提升了重污染企业的绿色形象。进一步研究发现：绿色并购可通过提升绿色创新和社会责任水平塑造重污染企业的绿色形象;绿色并购塑造绿色形象存在明显的作用场域,主要发生于高管有绿色经历、上市公司位于环境重点城市和上市公司属于高质量人才密集型企业的情境下。将绿色并购与绿色形象相结合,不仅可拓展绿色并购的理论框架,同时,对企业践行绿色发展理念、树立良好形象亦具有重要参考意义。     

MONEY AND GROWTH IN A RICARDO-VON NEUMANN-LEWIS WORLD

It is well known (Tobin (1965)) that in a monetary economy with full employment the monetary growth rate uniquely determines the steady-state capital intensity of the economy. This paper demonstrates that portfolio balance in a Ricardo-Von Neumann-Lewis world implies that the steady-state growth rate of the economy (the rate of capital accumulation) is uniquely determined by the rate of monetary growth. An increase in the monetary growth rate increases the steady-state inflation rate which, through its effect on savings, increases the equilibrium growth of the economy.     

Who should practice price discrimination using rebates in an asymmetric duopoly?

Price discrimination is generally thought to improve firm profits by allowing firms to extract more consumer surplus. In competition, however, price discrimination may also be costly to the firm because restrictive incentive compatibility conditions may allow the competing firm to gain market share at the discriminating firm’s expense. Therefore, with asymmetric competition, it may be the case that one firm would let the other firm assume the burden of price discrimination. We investigate optimal segmentation in a market with two asymmetric firms and two heterogeneous consumer segments that differ in the importance of price and product attributes. In particular, we investigate second-degree price discrimination under competition with explicit incentive compatibility constraints thus extending prior work in marketing and economics. Focusing on the managerial implications, we explore whether it would be profitable for either or both firms to pursue a segmentation strategy using rebates as a mechanism. We identify conditions under which one or both firms would want to pursue such segmentation. We find that segmentation lessens competition for the less price-sensitive consumer segment and that this results in higher profits to both firms. A key to understanding this result is that segmentation leads to consumer remixing. We establish the key result that if firms are asymmetric in their attractiveness to consumers, the disadvantaged firm in our model is more likely to pursue a segmentation strategy than its rival in equilibrium. We then ask whether this result prevails in practice. To this end, we explore competitive segmentation empirically and are able to verify that disadvantaged firms indeed pursue segmentation through rebates with greater likelihood.

Leverage-reducing exchange offers and bondholder–stockholder wealth transfers: A re-evaluation

This paper re-examines the intersecurity wealth effects of leverage-reducing exchange offer (LREO) announcements. We show that previous studies may have been confounded by not distinguishing between two types of LREOs – swaps and exchange offers – and by the limited availability of bond data to properly test the wealth transfer effect. Contrary to extant research, we find evidence supportive of the wealth transfer hypothesis in the case of exchange offers but not swap offers. More detailed analysis of LREO exchange offers reveals a systematic relationship between bond returns and certain attributes that capture managerial inclination to accede to bondholder interests, consistent with a wealth transfer effect.
