内在货币竞争均衡与时间不一致问题分析

以存款、债券和通货为变量考察内在货币私营发行和政府预算约束对货币竞争均衡和时间不一致问题的影响,可从理论上解决外在货币内在化的可行性,以避免内在货币制度中搞恶性通货膨胀从而实现利润最大化等.随着内在货币竞争加剧、外在货币被逐渐逐出、高通货膨胀率等问题出现,要求政府承诺和声誉机制共同作用解决这些问题,只有人们认为政府承诺可信和竞争性货币有声誉,并且内在货币发行者意识到只有维护企业声誉并维持政府权威才能在竞争中保持利润,时间不一致问题才能得以避免.

Synergy among Seemingly Independent Activities*

“Synergy” implies that the value of activities undertaken jointly is greater than the sum of the values of the individual activities. Reasons cited for synergy include economies of scale, benefits due to vertical integration, and efficiency gains from shared inputs and skills. This paper shows that incentive (control) reasons alone can make activities synergistic. The result is derived in a model of adverse selection with risk‐neutral participants and linear technology. The linearity in the setting removes any obvious benefits to undertaking activities in tandem. Synergy gains are attributed to a convexity in the principal's payoff introduced by the activities' impact on the production versus rents trade‐off.     

The attributes,behavior, and performance of U.S. mutual funds

This article examines the risk and return characteristics of U.S. mutual funds. We employ an equilibrium version of the Arbitrage Pricing Theory (APT) and a principal-components-based statistical technique to identify performance benchmarks. We also consider the Capital Asset Pricing Model (CAPM) as an alternative. We implement a procedure for overcoming the rotational indeterminacy of factor models. This procedure is a hybrid of statistical factor estimation and prespecification of factors. We estimate measures of timing ability for the CAPM and extend it to the APT. We find that this timing test is misspecified due to noninformation-based changes in mutual fund betas. We develop a modification of the timing measure that, under certain conditions, distinguishes true timing ability from noninformation-based beta changes.

Capital theory and the origins of the elasticity of substitution (1932-35)

Elasticity of substitution was introduced into economics duringthe early 1930s. It was discovered independently by Hicks inThe Theory of Wages and by Joan Robinson in The Economics ofImperfect Competition, and then was the centre of a polemicinvolving Kahn and Sraffa, among others. The debate focusedon imperfect competition and capital-theoretical issues. Someelements of the 1950s and 1960s capital theory controversy,such as the idea of capital as a Giffen good or the difficultiesof measuring capital, were already discussed at this early stage.     

基于人力资本价值链理论的中国城市国际人才集聚研究

城市国际人才争夺战由来已久并不断升级，但针对中国城市国际人才集聚水平、影响因素和差异化政策供给的研究鲜见。以“国际人才集聚指数-国际人才集聚影响因素-国际人才集聚政策”为研究主线，以中国36个主要城市为研究对象，创新性地通过构建人力资本“投入-过程-产出”价值链理论模型进行实证研究，结果表明：中国城市国际人才集聚指数排名分为3个差异显著的层级。其中，第二和第三层级之间无较大差距，但与由北京、上海组成的第一层级相比大幅落后。中国城市国际人才集聚影响因素分化明显，第一类城市的主要影响因素为全球城市品牌文化；第二类城市为创新型经济发展；第三类为外资传统工商业企业和产业集聚。对应地，中国城市国际人才集聚政策供给围绕外资传统工商业国际人才集聚、高端生产性服务业国际人才集聚、多样性和包容性国际人才文化氛围营造存在三大差异化选择。首次构建人力资本“投入-过程-产出”价值链模型，为从机理上深入探索中国各类城市国际人才集聚模式及提升路径奠定了基础。     

电子商务时代的技术创新、人力资本与经济增长

本文将技术创新、交易成本和人力资本引入经济增长模型，求出最优人力资本投入．并结合交易成本分析电子商务对经济增长和人力资本的影响。研究发现，在新经济时代．由于技术创新和知识累积使交易成本降低，就长期而言，人们会增加入力资本用于生产的比例．而减少用于教育的比例。在静态均衡分析中，本文进一步讨论人均消费、人均产出和人均资本增长率与交易成本、技术创新及知识累积的关系。     

Toward a Positive Theory of Corporate Financial Policy

This paper offers an alternative theoretical structure to the neoclassical valuation model that has been the cornerstone of theories of finance for a quarter of a century. It begins by outlining the neoclassical model in simple but surprisingly robust terms. More recent extensions and refinements are then discussed. The alternative model, which does not rely on modern financial economic theory but which is consistent with real world empirical behaviour, is developed next. Finally, a new research agenda for finance is proposed.
