China’s telecommunications evolution,institutions, and policy issues on the eve of 5G: A two-decade retrospect and prospect

Over the past two decades, China’s telecommunications industry has witnessed drastic market reform, steadfast institutionalization, and volatile technological changes, which have driven exponential industry expansion. This paper offers an updated longitudinal and comprehensive review on this reform process on the eve of 5G (the fifth generation mobile communications networks). First, the paper segments the two-decade reform crusade into discernible phases, each of which is embedded with different policy drives. These reform phases are then pattern-matched against the subtleties of the overall institutional, technological, and market backdrop. A series of policy issues are identified through a systematic examination of industry phenomena over the reform course. Finally, the status of research is assessed regarding China’s telecom industry and reform, based on which, knowledge gaps are identified and future research agenda suggested. Conclusions are made regarding future reform and research imperatives. The paper advances the understanding of China’s telecom reform, development, and the underlying policy issues. It updates and expands previous works on similar topics. Overall, this study provides important theoretical, managerial, and policy implications.

结构变化下中国股市单位根现象研究

本文使用含结构变化的单位根检验理论来分析上证综指、上证A指、上证B指和深证成指日收盘价格对数过程的特征.本文的实证结果表明,上证综指、上证A指、上证B指和深证成指日收盘价格对数过程存在结构变化,结构中断点位置表明交易费用调整事件和利率调整事件对A股市场有较深刻影响,这和一些文献将"1995年01月01日实行T 1交易制度"或"1996年12月16日实行涨跌停板"作为分界点有所不同;在考虑结构变化因素后,深市的有效性不如沪市.     

Determinants of the 1991–1993 Japanese recession: Evidence from a structural model of the Japanese economy

The objectives of this paper are to determine the extent to which various factors contributed to the most recent recession in Japan and to assess whether the recent behavior of the Japanese economy differs from that in previous recessions. Toward that end, we develop a small, structural macroeconometric model of the Japanese economy and estimate it using data from 1971 Q1 to 1991 Q1, the period just prior to the recent downturn. The important results can be summarized as follows. First, the severity of the recent recession probably does not reflect structural economic changes. Second, the poor economic performance in 1991–1993 period was to some extent predictable, reflecting the unwinding of imbalances that developed during the preceding expansion. Finally, unpredictable movements in exchange rates, land prices, and stock prices occurring after 1991 played an important, but not predominant, part in accentuating the downturn, while unusually stimulative fiscal and monetary policies appear to have contributed substantially to GDP during the recession.     

Nominal shocks and the current account: A structural VAR analysis of 14 OECD countries

This paper provides some empirical evidence on one of the most controversial theoretical implications of the new open economy literature, which refers to the role of the current account in the international monetary transmission mechanism. In order to throw some light on this issue, two structural VAR models are estimated separately for 14 industrialized countries. The main empirical results highlight the importance of the role of nominal disturbances for current account fluctuations. Additionally, it is found that expansionary nominal shocks generate temporary current account surpluses, whose size is positively correlated with the openness of the individual countries. JEL no.

Policy matters. The long run effects of aggregate demand and mark-up shocks on the Italian unemployment rate

This paper estimates a VAR including labor productivity, real wage and unemployment rate, to identify the dynamic effects of technology, demand, and mark-up shocks, respectively, on the Italian labor market. Identification is achieved by imposing recursive restrictions on the matrix of long run multipliers. Our results show that both mark up and aggregate demand shocks permanently reduce the unemployment rate. Finally, technology shocks do not significantly affect the unemployment rate in the long run. These findings convey important policy implications: expansionary aggregate demand and deregulation policies reducing the mark up permanently decrease the Italian unemployment rate.Jel classification: C32, E32, J29This paper has been produced as part of a CEPR Research Network on New Approaches to the Study of Economic Fluctuations.

Informal economy, wage goods and accumulation under structural adjustment theoretical reflections based on the Tanzanian experience

Economic development in sub-Saharan Africa under structuraladjustment witnessed the upsurge of informal sector development—thedevelopment of unregulated labour-intensive activities, in partexport-oriented. This paper argues that two factors played animportant role in shaping the dynamics of informal sector development:(1) the process of the relative cheapening of wage goods asa result of their importation, partly financed through foreignaid, thereby lowering unit-labour costs in labour-intensiveproduction, and (2) the processes at work of subsidising realwages by other forms of economic security as a result of multiple,diversified and spatially extended livelihood strategies. Whilethese factors undoubtedly brought a new vitality to economicdevelopment, this paper questions the long-run sustainabilityof this new trend for two reasons. One is its dependence onforeign aid to finance imports. The other is that it does notappear to propel endogenous increases in productivity by achievinggreater synergy in intersectoral linkages between agricultureand industry.     

Information reduction via level crossings in a credit risk model

This paper provides an alternative credit risk model based on information reduction where the market only observes the firm’s asset value when it crosses certain levels, interpreted as changes significant enough for the firm’s management to make a public announcement. For a class of diffusion processes we are able to provide explicit expressions for the firm’s default intensity process and its zero-coupon bond prices.      

我国公共基础设施的规模效应及结构效应分析——基于1996-2010的制造业行业数据

基于三要素的成本函数,本文利用1996—2010年20个制造业行业的面板数据,考察了以能源、交通以及邮电通讯为代表的公共基础设施对产业部门的要素投入数量以及要素投入结构的影响。结果表明:公共基本设施投入不仅具有降低行业平均成本的作用,而且对行业成本结构具有显著影响。相对于劳动投入,要素投入更加向资本和中间品倾斜。     

Structural and executional drivers of downstream revenue

Revenue flows that occur at other related organizational units and over time are an important part of customer profitability analysis and resource planning. This study analyzes downstream revenue generated from establishing a series of additional organizational units. The setting is a central hospital which established a group of specialty outreach clinics. Using a specially-collected time-series database I show two distinct patterns, depending on the clinic's specialty. One type triggers immediate incremental downstream revenue to the clinic's sponsoring department. The other type of clinic generates revenue that is smaller in value, later in time and mostly in departments not associated with the sponsoring department's medical specialty. Structural and executional clinic characteristics such as distance and clinic frequency differentially affect the amount of revenue generated, implying a need for tailoring performance measures to “clinic type”. Overall, my results suggest caution in developing performance measures that include financial impact in other organizational units – context matters even in a relatively homogenous setting of specialty clinics in one hospital system.
