A survey of network-based analysis and systemic risk measurement

The financial crisis led to a number of new systemic risk measures and a renewed concern over the risk of contagion. This paper surveys the systemic risk literature with a focus on the importance of contributions made by those emphasizing a network-based approach, and how that compares with more commonly used approaches. Research on systemic risk has generally found that the risk of contagion through domino effects is minimal, and thus emphasized focusing on the resiliency of the financial system to broad macroeconomic shocks. Theoretical, methodological, and empirical work is critically examined to provide insight on how and why regulators have emphasized deregulation, diversification, size-based regulations, and portfolio-based coherent systemic risk measures. Furthermore, in the context of network analysis, this paper reviews and critically assesses newly created systemic risk measures. Network analysis and agent-based modeling approaches to understanding network formation offer promise in helping understand contagion, and also detecting fragile systems before they collapse. Theory and evidence discussed here implies that regulators and researchers need to gain an improved understanding of how topology, capital requirements, and liquidity interact.     

Childhood investments and skill formation

The skills needed to ensure good life chances are rising (and changing) and, despite decades of education reforms, there has been little progress in terms of equalizing opportunities. The impact of social origins on child outcomes persists, and may even strengthen. This suggests that the pursuit of more equality and future productivity come together. A major challenge is to minimize the dispersion of skills. The foundations of policy lie in the realization that learning abilities are formed during the first years of childhood. The pursuit of an optimal human capital policy needs to consider three issues: (1) the uneven capacity of parents to invest in children; (2) the impact of mothers’ employment on child outcomes; and, (3) the potential benefits of early pre-school programmes.     

Herstellung von Wettbewerb durch Übertragung der Alterungsrückstellung in der Privaten Krankenversicherung

The system of individual prospective aging reserve enables the insured persons irrespectively of their individual risk to change their Private Health Insurance. Besides the presentation of an implementation concept it is shown that there is no inducement to miscalculate the extent of the individual prospective aging reserve on purpose.     

Borrowing constraints,the cost of precautionary saving and unemployment insurance

When it is costly for individuals to save or to borrow, unemployment insurance (UI) provides an alternative source of liquidity that smooths consumption over time and leads individuals to spend longer unemployed searching for a suitable job. We show in a tractable life-cycle model how the optimal unemployment replacement ratio and the fall in consumption on job loss depend on the cost of self-insurance and the cost of borrowing. This implies that the value of UI depends on age at job loss, consumption needs (such as the presence of children), discount rates, the return on saving, access to credit and the presence of other social insurance programmes. Optimal replacement rates vary substantially with plausible variation in these factors (from less than 20 percent to almost 60 percent).     

Binary response and logistic regression in recent accounting research publications: a methodological note

We review 31 articles in leading accounting journals that performed a logistic regression analysis for a binary dependent variable. Our review shows that many of these articles have ambiguities and errors in the presentation of the logistic regression model. We explain that incorrect presentations of the model, even in conjunction with a correct analysis, may lead to a serious misinterpretation of research findings. Two articles are critiqued to demonstrate the reporting problems. Our note is a call for improvement in model presentation and related statistical analysis in the accounting field.     

Casino Revenues and Retail Property Values: The Detroit Case

We analyze the effects of commercial casinos on retail property values in the Detroit urban area. Accounting for property characteristics and proximity to the casinos, casinos are found to have a significantly positive influence on retail property values. The effect is stronger within a 5-mile radius of the casinos, suggesting that casinos have a complementary, rather than substitution, effect on other businesses. This provides some of the first micro-level empirical evidence to support the “drawing power” of casinos and the impact of consumer spending on surrounding businesses. The model developed and tested in this study can be applied to other casino jurisdictions to gain further evidence on the impact of commercial casinos.     

Zur Integration heuristischer Managementstrategien in die Dynamische Finanzanalyse

Dynamic financial analysis (DFA) has become an important tool in analyzing the financial situation of insurance companies. Constant development and documentation of DFA tools has occurred during the last years. However, several questions concerning the implementation of DFA systems have not been answered in the DFA literature to date. One such important issue is the consideration of management strategies in the DFA context. The aim of this paper is to study the effects of different management strategies on a non-life insurer’s risk and return profile. Therefore, we extend the results of a recent working paper by Eling / Parnitzke / Schmeiser (2007) with two variants and test these variants numerically within a DFA simulation study.     

The impacts of product market competition on the quantity and quality of voluntary disclosures

This study examines how firms’ voluntary disclosure decisions are influenced by product market competition. Using separate measures to capture different dimensions of competition, I show that competition from potential entrants increases disclosure quantity while competition from existing rivals decreases disclosure quantity. I also find that competition enhances disclosure quality mainly through reducing the optimism in profit forecasts and reducing the pessimism in investment forecasts. Moreover, I find that the above association is less pronounced for industry leaders, consistent with industry leaders facing less competitive pressures than industry followers.     

A Note on Utility Maximization with Unbounded Random Endowment

This paper addresses the applicability of the convex duality method for utility maximization, in the presence of random endowment. When the underlying price process is a locally bounded semimartingale, we show that the fundamental duality relation holds true, for a wide class of utility functions and unbounded random endowments. We show this duality by exploiting Rockafellar’s theorem on integral functionals, to a random utility function.     

Flood Hazards and Urban Housing Markets: The Effects of Katrina on New Orleans

This study examines the impacts on consumers’ willingness to pay for certain characteristics of housing in greater New Orleans before and after the flooding of Hurricane Katrina. Single-family home sales from January 2004 to August 2006 are collected and used in a hedonic price function to estimate the changes in the value of amenities, and structural, neighborhood and geographic characteristics, including the mean elevation of each property. Elevation, which buyers did not know for certain prior to the storm, but may now be inferred from water level marks in most neighborhoods, is found to have a positive relationship with selling prices. Results indicate that pre-Katrina, there was a premium of only 1.4% per foot in flood-prone areas, and was insignificant in areas not subject to flooding. This increased to 4.6% for flooded areas after Katrina. These findings are attributed to not only the perceived risk of flooding, but also to the potential of higher compliance costs associated with rebuilding under more stringent National Flood Insurance Program (NFIP) guidelines.
