Insurance Derivatives: A New Asset Class for the Capital Markets and a New Hedging Tool for the Insurance Industry

The number and severity of natural catastrophes has increased dramatically over the last decade. As a result, there is now a shortage of capacity in the property catastrophe insurance industry in the U.S. This article discusses how insurance derivatives, particularly the Chicago Board of Trade's catastrophe options contracts, represent a possible solution to this problem. These new financial instruments enable the capital markets to provide the insurance industry with the reinsurance capacity it needs. The capital markets are willing to perform this role because of the new asset class characteristics of securitized insurance risk: positive excess returns and diversification benefits.
The article also demonstrates how insurance companies can use insurance derivatives such as catastrophe options and catastrophe-linked bonds as effective, low-cost risk management tools. In reviewing the performance of the catastrophe contracts to date, the authors report promising signs of growth and liquidity in these markets.     

Audit personnel salaries and audit quality

This study examines the relation between audit personnel salaries and office-level audit quality. We measure audit personnel salaries at the associate, senior, and manager ranks for Big 4 audit offices from 2004 to 2013, using unique individual-auditor-level data obtained from the U.S. Department of Labor. We find that offices that pay lower salaries have a higher percentage of clients that experience restatements. In related analyses, we also find lower levels of audit quality when audit employees are paid less, relative to other lines of service in accounting firms. Finally, we document positive and significant associations between salary and fees, suggesting that audit offices pass some of the cost of higher labor onto their clients. Overall, our findings provide important initial evidence on the role of audit salary and its relation to audit quality and audit fees.     

Ecological integrity as an economic variable: An application to forested landscapes in the southern United States

Ecological integrity is important to fully describe the development of an economy. We calculated an aggregate index that quantifies the closeness of a forested region to a natural state. This naturalness index was based on the diversity of native tree species and sizes for ecological subregions in a seral condition. The index used the spatial–temporal array of sample plots from the Forest Inventory and Analysis (FIA) database of the USDA Forest Service. In the 70 survey units of the southern US between 1961 and 2005 the naturalness of forests generally improved with per capita personal income and population. The increase with income was consistent with the hypothesis of an environmental Kuznets curve for forested landscapes.     

能源博弈与互依共存

一场围绕能源的新的大博弈即将来临。推动这一大变化的最主要力量是全球对于气候变化和能源安全的共同关注。在这场博弈中,国家利益在传统的市场规则中扮演越来越重要的角色。对于生产国和消费国来说,共同的挑战是认清互相依存的现实并为达成谅解而建立组织框架。中国目前的发展正锁定其能源消费模式从而带动未来数十年的能源需求。从消费角度来讲,中国、印度和美国在决定这场全球能源博弈规则的过程中,将扮演最重要的角色。资源民族主义的崛起以及全球寻找能源的行为,正迫使每个国家重新考虑各自的外交政策以及联盟关系。国家石油企业正寻求私营石油公司的技术,二者需要建立起与过去不同的新型合作关系。气候变化和能源安全带来的大变化大挑战,是这场能源大博弈的所有参与者都要面对的。关键在于创建可转化为互相信任和依存关系的利益平衡的理解框架。     

A note on net present value and internal rate of return functions in electronic spreadsheets

Academic accountants are increasing their use of electronic spreadsheets in teaching. The net present value functions of some popular spreadsheets make incorrect calculations. The internal rate of return functions do not handle multiple rates in a standard way.     

Government Supply of Land in a Dual Market

A dual land market is one in which the government owns a significant portion of developable land while real estate development is done primarily by the private sector. This article examines Singapore's experience with its system of government land supply in a dual market, focusing on its response to market signals as well as the interaction with the significant private supply of land. The example is relevant to the general problem of government sales of valuable assets. The private supply of developable land behaves in line with expectations. The government response to price signals differs only modestly from that of private landowners.     

Firm Efficiency Differences and Distribution in the Kenyan Manufacturing Sector

Abstract: This article provides empirical evidence on technical efficiency differences and efficiency distribution for three Kenyan manufacturing subsectors, namely food, metal and textile, using an unbalanced panel data covering two periods. Econometric production frontiers are estimated for each subsector in each period. The confidence predictions for these efficiencies were, however, found to be quite wide. The results indicate variation of technical efficiency estimates of the sampled firms in each period. The technical efficiency distribution for each subsector changed not only in relation to itself, but also in relation to the other subsectors across the two periods of analysis. The efficiency distribution of the firms for both food and textile (metal) subsectors improved (declined) during the study period but with the food subsector firms remaining relatively inefficient. The improvement of the technical efficiency distribution for both the textile and food subsectors is an indication of intra‐plant improvement during the period of analysis. The decline of the technical efficiency distribution for the metal subsector suggests that the market orientation during the structural reform period did not promote firm efficiencies or the firms were slow in responding to the reforms.
