Assessing the impact of AIDS on the growth path of the Malawian economy

More than 1% of people of sub-Saharan Africa aged 15-49 years are infected with HIV, with over half likely to develop AIDS in the next decade. As rates of HIV infection continue to climb, there will be staggering financial consequences to bear in the years ahead in terms of high medical treatment costs and crippled macroeconomies. The authors employ a modified Solow growth model to simulate the impact of the AIDS epidemic on output capacity and other key macroeconomic aggregates in Malawi. They compare a counterfactual no-AIDS scenario to medium and extreme AIDS projections and find that average real GDP growth over the 1985-2010 period will be 0.2-0.3 percentage points lower in the medium case and 1.2-1.5% lower in the extreme case relative to the no-AIDS case. The size of the economy by 2010 will therefore be reduced from a real GDP of 5.03 billion (constant 1985) Kwacha without AIDS to 4.81-4.77 and 3.80-3.46 billion Kwacha in the medium and extreme scenarios, respectively.     

Bank Capital and the Credit Crunch: The Roles of Risk-Weighted and Unweighted Capital Regulations

We investigated whether in recent years banks have increased their holdings of securities at the expense of their holdings of business loans in response to shortfalls of their capital relative to risk-weighted capital standards and relative to a capital standard that made no explicit allowance for credit risk. We estimated that bank credit fell by about $4.50 for each $1 that a bank's capital fell short of the unweighted capital standard. Banks that had less capital than required by the risk-weighted standard appear to have shifted away from assets with low risk weights (securities and single-family mortgages) and to have shifted toward assets with higher risk weights (commercial real estate and commercial and industrial loans). When we included both shortfall variables in a regression, shortfalls relative to the unweighted capital standard significantly affected bank credit, while shortfalls of capital relative to the risk-weighted standard did not. We found no significant effects of capital shortfalls at other, local-competitor banks on bank portfolios. Delinquencies in a given category of a bank's loans generally had significantly negative effects on that bank's holdings of loans in that category. In contrast, banks tended to increase holdings of loans in categories in which local-competitor banks were experiencing higher delinquency rates.     

Value Creation in the Insurance Industry

Using the insights of current research in corporate finance and financial institutions, the authors briefly present a consistent economic framework for looking at insurance. Shareholders of insurance companies provide risk capital that is invested in financial assets and therefore earns the market return of the assets it is invested in. However, due to the legal and fiscal environment insurance companies are in, they have a competitive disadvantage at investing, and this gives rise to frictional capital costs. The core competence of insurers is in managing the size of these frictional capital costs. Insurers must ensure that they can sell insurance for a price in excess of what they need to produce the cover they sell and compensate the incurred frictional costs on risk capital. It is through the ability to do so that insurers create shareholder value.     

Identifying Decision Useful Information with the Matrix Format Income Statement

We conduct an experiment to investigate the potential benefits of an alternative format for the income statement, the matrix format, initially developed by the International Accounting Standards Board (IASB) and UK Accounting Standards Board in their joint project on performance reporting. Sophisticated financial statement users (financial analysts and professional accountants) and less sophisticated financial statement users (MBA students) were asked to extract information from a set of financial statements that included an income statement either in the IAS 1 format or in the matrix format. We find that the matrix format improves the accuracy with which users extract financial information. This result is driven by greater accuracy, for all user groups, on “below‐the‐line” items. Furthermore, despite lack of familiarity with the matrix format, its use did not appear to affect the time taken, the ease of extracting financial information, or users' task completion confidence; further experience with the matrix format could lead to benefits along these lines as well. Our findings may assist the FASB and IASB in their joint project on financial statement presentation.     

The Metamorphosis of Australian Industrial Relations

This article outlines the current processes of change in Australian industrial relations - processes whose ultimate direction and effects are unforeseeable. The traditional dominance of conciliation and arbitration tribunals is giving way to more devolved arrangements. Some protagonists of change envisage a move towards collective bargaining, with trade unions having a pervasive and secure role; others believe the place of unions is in question. The impulse for change comes partly from market-oriented ideology, but this is not extensively discussed, A second source is the desire of the Australian Council of Trade Unions and the Labor Government to determine wage policy jointly, with the role of the Australian Industrial Relations Commission being essentially that of implementation. Also important is a widely held view that reform of industrial relations is a path to better productivity performance. The paper discusses the justification for that view. Various questions remain to be answered. These include the possibility for enduring wages policy; the legal framework necessary for bargaining; the nature of the industrial relations system of non-union enterprises; and the congruence of enterprise bargaining with the structure of trade unionism.     

Keeping up or Falling behind? The Impact of Benefit and Tax Uprating on Incomes and Poverty*

Each year, the government decides how much to raise benefits and tax allowances. In the UK, the basis for these upratings is rarely debated, yet has major long‐term consequences for the relative living standards of different groups as well as for the public finances. This paper considers the medium‐term implications of present uprating policies, which vary across parameters of the tax–benefit system. Continuing these policies for 20 years, other things staying the same, would result in a near doubling of the child poverty rate alongside a substantial gain to the public finances. At the same time, pensioners are largely protected by the earnings indexation of pensioner benefits including, in time, the basic state pension. We show how difficult it will be to meet the UK child poverty targets unless the greater inequality inherent in the current regime for uprating payments and allowances is redressed.     

Variance of the CTE Estimator

Abstract

The Conditional Tail Expectation (CTE), also called Expected Shortfall or Tail-VaR, is a robust, convenient, practical, and coherent measure for quantifying financial risk exposure. The CTE is quickly becoming the preferred measure for statutory balance sheet valuation whenever real-world stochastic methods are used to set liability provisions. We look at some statistical properties of the methods that are commonly used to estimate the CTE and develop a simple formula for the variance of the CTE estimator that is valid in the large sample limit. We also show that the formula works well for finite sample sizes. Formula results are compared with sample values from realworld Monte Carlo simulations for some common loss distributions, including equity-linked annuities with investment guarantees, whole life insurance and operational risks. We develop the CTE variance formula in the general case using a system of biased weights and explore importance sampling, a form of variance reduction, as a way to improve the quality of the estimators for a given sample size. The paper closes with a discussion of practical applications.
