Capitalization of Flood Insurance and Risk Perceptions in Housing Prices: An Empirical Agent‐Based Model Approach

Federally regulated or insured lenders in the United States are mandated to require flood insurance on properties that are located in areas at high risk of flooding. Despite the existence of this mandatory flood insurance requirement, take‐up rates for flood insurance have been low, and the federal government's exposure to uninsured property losses from flooding remains substantial. Meanwhile, the value of capital at risk varies significantly with flood events and changing risk perceptions, which necessitates mechanisms that stabilize these dynamics. In this article we discuss how a scenario of complete insurance uptake, under various risk attitudes, affects the value of properties in the 100‐year and 500‐year flood zones. Our results indicate that an increase in flood insurance uptake may provide such a mechanism by lowering the value of capital at risk in the flood zone consistently, independent of homeowners' risk attitudes. We apply an empirical adaptive agent‐based model to examine the capitalization of insurance costs, risk premiums, and their interaction in housing prices. Our approach combines widely‐used empirical hedonic analysis with the computational economic framework. We highlight the usefulness of our method in capturing the marginal implicit price of homeowners' preferences that may change over time and separately assess the effect of various factors and policies on property values, illustrating the agent‐based modeling as a valuable complement to traditional hedonic analysis.     

Reasonable and Risk‐Based? Replacing NFIP Generally Subsidized Rates with a Means‐Tested Subsidy

The National Flood Insurance Program was created to seek two often conflicting goals: (i) shifting risks from federal taxpayers to those who choose to live in flood plains and (ii) ensuring flood insurance is available to everyone at “reasonable” rates. Efforts to accomplish the second goal currently take the form of subsidies based on location and the date a home was constructed. The resulting revenue from subsidized insurance premiums is not sufficient to cover the true cost of flood insurance, and federal taxpayers have paid the difference: $30 billion to date. Based on a detailed survey of households in the high‐risk flood zones of New York City (NYC), we find that replacing existing premium subsidies with risk‐based prices and a subsidy for low‐income housing‐burdened households could better meet both goals by ensuring low‐income individuals have access to affordable flood insurance while still saving the federal taxpayer up to $183 million per year in NYC alone.     

中国企业研发经费投入现状及国际比较

企业是开展创新活动的重要主体,加强企业研发经费投入对提升企业技术创新能力至关重要。本文基于《欧盟产业研发投资记分牌(2019)》和调研数据,从研发经费投入及结构视角分析了我国企业创新活动现状,并与世界主要创新型国家进行了国际比较分析。研究发现:我国企业研发经费投入规模不断扩大,企业已经是研发经费投入主体和执行主体;相比国有企业,民营企业更具研发投资动力,是企业研发经费投入主体;我国企业研发经费投入增速较高,但研发经费投资规模和强度低于世界主要创新型国家;我国企业科学研究经费布局明显低于世界主要创新型国家,严重制约企业自主创新能力提升;我国企业基础研究占比偏低与创新特性、企业使命、发展阶段、企业能力、体制机制等因素有关,新时代应重点引导和激励更多企业向"爱迪生象限"和"巴斯德象限"跃升。     

基于系统动力学的研发投资预算研究

研发投入是一种高风险的投资,研发投入过多或过少都不利于企业的发展,而如何在企业资源有限的情况下,合理安排研发投入以获取持续的竞争能力是企业研发管理的重点。应该说,研发投入系统是一种复杂的系统,本文首先对研发投资预算的方法进行了回顾,继而提出了运用系统动力学编制研发投资预算的思路并构建了基于系统动力学的研发投资预算模型,该模型将研发系统分为研发流程、研发团队和现金流等三个子模块并描述了研发投资预算的影响因素及其作用过程,最后,以电子产品为例运用该模型模拟了四种不同研发投资预算方案的效果。     

美国2011年财政研发预算重点与趋势分析

An investigation of issues relating to where energy should enter the production function

This paper examines the impact of imposing different separability assumptions in the specifications of the standard hierarchical KLEM production function in a computable general equilibrium (CGE) model. The appropriate means of introducing energy to production functions has been a source of debate for a number of years. However, while modellers often subject results to parametric sensitivy analysis regarding the values associated with elasticities of substitution between inputs, it is rarely the case that the structure of the production function is subjected to testing. However, the chosen structure reflects the modeller's view about elasticity between different inputs and will have implications for model results wherever there are changes in relative prices. We illustrate our argument by introducing a simple demand shock to a CGE model of the Scottish economy (targeted at the energy supply sector) under different assumptions regarding the structure of the KLEM production function and separability assumptions therein.     

A direct test of hyperbolic discounting using market asset data

This paper introduces a framework that generalizes exponential discounting in a net present value model by including a quasi-hyperbolic discount parameter in the asset valuation equation. Using observed market asset data, a statistically significant quasi-hyperbolic parameter is obtained, thus rejecting exponential discounting.
