基于AD9361的掌上型LTE RRU设计与开发

当前小体积远端射频单元（Remote Radio Unit,RRU）主要是皮站级别的Pico-RRU，其重量和体积仍然难以满足掌上型的要求。为此，采用高集成度的AD9361芯片来实现长期演进（Long Term Evolution，LTE）宽带收发信机功能，配合时钟同步模块、放大器模块和控制接口电路等一起构建低成本的掌上型RRU。主要解决了基于AD9516的时钟同步、低相位噪声设计和高灵敏度接收机设计三个技术难点，成功实现了掌上型、高性能、低成本的设计目标。整个RRU样机尺寸为18 cm×10 cm×2 cm，质量约500 g，量产成本千元以内。测试表明，该RRU下行误差向量幅度（Error Vector Magnitude，EVM）小于3%，优于3GPP要求的8%；10 MHz带宽时上行接收机灵敏度优于3GPP要求的-93.5 dBm。     

Unemployment insurance benefits and income smoothing

Labor unemployment insurance reduces unemployment concerns. We argue that these benefits moderate incentives to smooth earnings to reduce employees’ concerns about unemployment risk. Using exogenous variations in unemployment insurance benefits, we find evidence consistent with this argument. We also find that the link between unemployment insurance benefits and income smoothing is stronger when there is higher unemployment risk and when the firm is likely to employ more low-wage workers, who find unemployment insurance benefits especially useful. Our paper contributes to the literature by showing that public policy decisions such as unemployment insurance have significant, albeit probably unintended, externalities on corporate financial reporting.

A MODEL OF BUREAUCRACY AND CORRUPTION*

We analyze bureaucracy and corruption in a market with decentralized exchange and “lemons.” Exchange is modeled as a sequence of bilateral, random matches. Agents have private information about the quality of goods they produce and can supplement trade with socially inefficient bribes. Bureaucracy is modeled as a group of agents who enjoy centralized production and consumption. Transaction patterns between the bureaucracy and the private sector are fully endogenous. Centralized production and consumption in the bureaucracy give rise to low power incentives for the individual bureaucrats. As a result, private agents might bribe bureaucrats, whereas they do not bribe each other. An equilibrium with corruption and an equilibrium without corruption can coexist. We discuss some welfare implications of the model.     

Fiscal decentralization, revenue and expenditure assignments, and growth in China

Theory suggests that a close match between revenue and expenditure assignments at sub-national levels benefits allocative efficiency, and hence economic growth. That is, a convergence of revenue and expenditure assignments at sub-national levels of government should, according to the theory, be positively associated with a higher growth rate. In the case of China, this paper shows, divergence, rather than convergence, in revenue and expenditures at the sub-national level of government is associated with higher rates of growth. A panel dataset for 30 provinces in China is used to examine the relationship between fiscal decentralization and economic growth over two phases of fiscal decentralization in China: (1) 1979–1993 under the fiscal contract system, and (2) 1994–1999 under the tax assignment system. The seeming contradiction between the theory and evidence in the China case is reconciled by taking into account the institutional arrangements that prevailed during the two phases of fiscal decentralization, in particular the inconsistency between the assumptions of the theory of fiscal decentralization and the institutional reality of China.     

论当代中国私营资本原始积累的社会功效

伴随中国私营经济而发生的私营资本原始积累,对中国的经济社会发展,对加速中国的社会主义现代化建设,是功绩卓著的。中国之所以能在20世纪末达到小康,私营资本原始积累是立下汗马功劳的。在中国今后的全面小康社会建设中私营资本原始积累必将发挥越来越大的功效。     

广西农村居民消费结构数量分析

在对居民消费结构进行定量研究中,扩展线性支出系统模型被广泛采用.运用扩展线性支出系统模型对广西农村居民的消费结构进行数量分析表明：广西农村居民的恩格尔系数呈现明显下降态势,广西农村居民总的边际消费倾向为0.625,广西农村居民各项需求的收入弹性均为正值,说明随着收入水平的提高,需求量随之增加.总之,目前广西农村居民消费水平低下,消费结构不合理.     

中国资本账户自由化的战略

资本账户开放,过去一直被认为是跻身国际金融社会的先决条件,而现在却不再被认为是绝对必要的,至少,资本账户开放不再被认为是每个国家都急切希望实现的经济政策目标。认识到资本账户开放在20世纪90年代一些国家的货币和金融危机中可能扮演了增加金融脆弱性的角色之后,[1]对自由化速度的主流看法发生了微妙的变化。即使在长期资本账户开放仍然是一个希望达成的目标,但大多数经济学家都开始认为,对于从一个压抑的金融体系到一个完全自由化的体系的转型过程的处理必须慎之又慎。如果转型不是一蹴而就的,那么顺序问题就变得至关重要。整个转型…
