Savings and investments in the OECD: a panel cointegration study with a new bootstrap test

In this paper we test for the existence of a stable long-run savings–investments relationship in 18 OECD economies over the period 1970–2007. Although individual modelling provides only very weak support to the hypothesis of a link between savings and investments, this cannot be ruled out as individual time series tests may have low power. We thus construct a new bootstrap test for panel cointegration robust to short- and long-run dependence across units. This test provides evidence of a long-run savings–investments relationship in most of the countries, with USA the most notable exception. However, the elasticities generally smaller than 1 suggest that market imperfections mostly cause only partial home biases.     

A family portrait of Canada's most successful female entrepreneurs

In an attempt to study the factors contributing to the decision to become an entrepreneur, an intensive interview survey of 36 successful women entrepreneurs was conducted. The importance of paternal occupation and psychodynamic interactions with both the mother and father was highlighted. The study revealed mirror images of the patterns found to be correlated with male entrepreneurship.Dr. Belcourt is an Associate Professor, Atkinson College, York University.

Experiments in scientific computation on the PlayStation 3

The Sony PlayStation 3 (PS3) offers the computational power of a parallel processor at low cost, which makes it a great starter unit for development in parallel programming. To explore the capabilities of the unit, we took a simple ray tracing program and extended it to render triangulated height field data across the PS3’s 6 synergistic processing units (SPUs). We also implemented the heat averaging equation as a precursor to CFD analysis on the PS3. In our studies, we found the Cell engine in the PS3 to be a powerful machine, however great care must be taken while developing because its unique platform calls for many levels of optimization to ensure efficiency.     

Special interest groups and the allocation of public funds

I propose a fully rational model of government contracting that explains differences in local government spending from grants and other income. In this model, violations of fungibility arise from dynamic interactions between politicians and interest groups with the ability to raise funds for the local government. The predictions of the model are tested by exploiting unique features of windfalls received by states under a settlement with the tobacco industry. Although windfalls are legally unrestricted, the median state increased spending on tobacco control programs from zero to $2.30 per capita upon receipt of funds. The marginal propensity to spend on such programs is 0.20 from settlement revenue and zero from overall income. States which were not involved in the settlement lawsuits spend less. These results cannot be explained by existing models in the literature.     

High-age implications of postretirement risks

The retirement world of the future is challenging because of the decline in defined benefit plans, low savings rates in the United States, increased longevity and the failure of many people to effectively plan for retirement. Drawing on a variety of studies and public opinion surveys, the authors of this article explain why a system that relies too much on people providing for themselves will have segments of the population who have inadequate retirement incomes due to a number of gaps, which pose the most risk at advanced ages. These gaps can occur because of difficulties in managing postretirement risk, acquiring inadequate savings in the first place and problematic public perceptions about retirement income risks.     

How financial information disclosure affects risk perception. Evidence from Italian investors’ behaviour

This paper investigates how different representations of financial information may be appraised in terms of complexity and usefulness, and how financial disclosure influences individuals’ risk perception. By using a consumer testing analytical approach, we run a survey on a sample of Italian investors: 254 bank customers were submitted 4 different templates, each combining a different typology of data (historical and prospective) and framing (words, numbers and charts) to indicate the same level of risk and return of four real-life financial instruments. Representation formats partially overlap with those mandated by regulators and used within the financial industry. Results show that the perceived riskiness of financial products is affected by the way information is disclosed. Perceived complexity of the financial information disclosure intensifies perception of riskiness of the product solicited. Gender, age, personal traits, behavioural biases and financial knowledge, do also play a role. Overall, given investors’ heterogeneity and behavioural biases, neither simplifying disclosure nor a ‘one-size-fits-all’ approach may be sufficient to ensure correct risk perception and to prevent unbiased investment choices.
