Computer knowledge and earnings: evidence for Australia

This paper uses data on wage and salary workers in Australia in 1993 to examine the relation between computer knowledge and earnings. A unique feature of the data set that is used is detailed information on the types and levels of computer skills possessed by individual workers. The main objectives of the study are to contribute to understanding the magnitude and sources of the relation between computer knowledge and earnings. Similar to existing research it is found that there is a large and significant return to computer knowledge, but that the magnitude of the return is substantially reduced in regressions that include detailed occupation controls. Using the detailed information on workers’ computer skills the main finding is that earnings are significantly positively related to the number of types of skills and average level of skills possessed by a worker.     

Risk and the public service manager

The Department of Social Security's discussion document on equalizing state pension age is examined and put in context. The authors conclude that it takes too narrow a view of the equality issue, and argue for a more radical reappraisal of state pension provision for the 21st century.     

Foreign issuers in the U.S. PIPE market

We document that the use of private investment in public equity (PIPE) by foreign firms listed on U.S. exchanges is growing even faster than its use by U.S. firms. On average, foreign firm PIPE stock deals represent a similar proportion of the firm's market capitalization to U.S. firm PIPEs, but suffer less of a share price discount than U.S. firm PIPE issuances, a relation that is robust to consideration of exchange, deal size, share turnover and return volatility. We document that hedge funds are only small investors in foreign firm PIPEs issued in the U.S., which tend to be purchased by pensions, government funds and corporations. PIPE, in combination with the reverse merger method of going public, provides a cost-effective means for foreign firms to raise capital in the U.S. capital market.     

Democracy and Growth: Alternative Approaches

This article focuses on two previously unexamined aspects of the relationship between economic growth and democracy. First, the growth experiences of countries that experience significant changes in democracy are examined directly. Countries that democratize are found to grow faster than a priori similar countries, while countries that become less democratic grow more slowly than comparable countries. These differences do not seem to be due to differences in education or investment levels. Second, regression tree analysis suggests that democracy, along with initial income and literacy, contributes to the identification of regimes of countries facing similar aggregate production functions.     

Radical innovations in new product development and their financial performance implications: An event study of US manufacturing firms

At the dawn of the 21st century, global competition continues to increase at an accelerating rate and radical innovation is recognized as a potent weapon for firms to achieve sustainable competitive advantages. Academics, practitioners and consultants share the view that radical innovation is important to the long-term financial success of firms. Nevertheless, empirical studies on the relationship between radical innovation and firm performance have been dominated by survey research, which provided little concrete evidence on the financial impact of radical innovation. In this study we traced the financial performance of publicly traded manufacturing firms in the United States that introduced radical innovations over the period 1986-2000 and examined whether radical innovation could lead to superior financial performance in these firms. We employed the event-study method, matching each sample firm with a control group of firms in the same industry with similar pre-event performance and firm size. Our results show that while radical innovation helps firms maintain sales growth and return on sales (ROS), firm profitability in terms of return on assets (ROA) is not significantly improved. In fact, manufacturers suffer from a decline in profitability upon the introduction of radical innovations in new product development.     

The processes of defining corporate responsibility: a study of Swedish garment retailers' responsibility

Despite extensive research on corporate responsibility, little research exists on how the inter‐organizational processes of defining corporate responsibility develop. In this paper, we present a framework based on actor‐network theory (ANT) for analysing these processes. The developed framework is illustrated in a study of the redefinition of Swedish garment retailers' responsibilities for workers' rights at suppliers' factories between 1996 and 2004. We show that definition processes can be characterized as battles for the right to interpretation, and that traditionally non‐dominant actors can, at least temporarily, win these battles and dictate the development of the processes for defining corporate responsibility. We also show that definition processes can take an exclusionary form prohibiting certain actors from participating. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment.     

Do dividend initiations signal a reduction in risk? Evidence from the option market

We investigate whether dividends convey information about the risk of a company by examining the reaction of implied volatility in the option market to the announcement of a dividend initiation. Implied volatility decreases after the announcement and the magnitude of the decline in volatility is positively related to both the magnitude of cumulative abnormal returns (CAR) in the equity markets and the size of the dividend. Additionally, firms with weaker (stronger) corporate governance experience larger (smaller) declines in implied volatility. Cross sectional analysis shows that a one-standard deviation decline in measures of risk increases the 2-day CAR by 74–137 basis points. Our results suggest that dividend initiations signal declining firm risk.     

Is Democracy a Normal Good? Evidence from Democratic Movements

A frequent assertion of economists and political scientists is that democracy is a normal good, or that higher incomes lead citizens to “desire” more democracy. This assertion, however, has been difficult to test directly. I introduce a data set of democratic movements, and use it to address the relationship between income and the demand for democracy. Logit analysis of the estimated probability that a democratic movement occurs in an authoritarian country suggests that this probability is increasing in income per capita up to a level of approximately $5000. Unlike previous results, this does not suggest that all countries will become democratic once they pass some income threshold.     

Cannabis, Alcohol and Cigarettes: Substitutes or Complements?

This paper uses individual level data from the National Drug Strategy Household Surveys to estimate the price responsiveness of participation in cannabis, alcohol and cigarette use. In addition to own price effects, we estimate cross price effects and the impact of decriminalizing cannabis use. We find that participation is responsive to own prices. There is some evidence that cannabis is a substitute for alcohol and a complement to cigarettes, and that alcohol and cigarettes are complements. The liberalization of cannabis laws in South Australia may have led to a temporary increase in cannabis use among the over-30 age group.
