Rational inattention,long-run consumption risk,and portfolio choice

This paper explores how the introduction of rational inattention (RI) – that agents process information subject to finite channel capacity – affects optimal consumption and investment decisions in an otherwise standard intertemporal model of portfolio choice. We first explicitly derive optimal consumption and portfolio rules under RI and then show that introducing RI reduces the optimal share of savings invested in the risky asset because inattentive investors face greater long-run consumption risk. We also show that the investment horizon matters for portfolio allocation in the presence of RI, even if investment opportunities are constant and the utility function of investors is constant relative risk aversion. Second, after aggregating across investors, we show that introducing RI can better explain the observed joint dynamics of aggregate consumption and the equity return. Finally, we show that RI increases the implied equity premium because investors under RI face greater long-run consumption risk and thus require higher compensation in equilibrium.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.     

创新视阈下专利许可公司商业模式解构研究

Can the affordable care act provisions explain the recent wave of acquisitions in the health insurance industry?

This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year.     

新疆兵团农户借贷行为及其影响因素的实证研究

本文以新疆兵团农户调查为基础,研究了在新疆兵团特殊的金融供给制度下农户借贷行为特征,并运用TOBIT模型对农户借贷行为的影响因素进行实证分析。研究结果表明:种植规模、农业支出、金融供给制度对农户正规借贷具有正向影响,而地区差异则对其具有负向影响;种植规模、非农业经营支出、家庭资产状况、子女教育支出、借款用途对农户非正规借贷具有正向影响,而非农业经营收入、受教育年限、社会关系则对其具有负向影响。     

科学合理性的建构与解构

科学到底有无合理性是科学哲学的一个核心问题。从古希腊开始,对科学合理性的探讨与争论经历了几种不同的流派,但都只是对科学合理性的一鳞半爪式的理解。这其中的主要原因是以往的探讨都存在着人为上的对科学合理性的分割理解,将本来共处一个整体的合理性分解为对某一合理性层面的解释,这种还原主义最终导致了合理性地位的动摇。从各个流派对科学合理性的不断建构与消解进程中可以看到,作为科学合理性的一体两面的科学工具理性与价值理性应该是更进一步把握合理性问题的努力方向。
