Housing expenditure and neighbourhood economic development

In low-income neighbourhoods, with limited commercial and industrial development possibilities, the only major local investment opportunities tend to be associated with housing and environmental upgrading. However, when these investments take place the typical experience is that the residents of the area enjoy only limited employment and training benefits from the works carried out. This paper assesses a number of initiatives where serious attempts have been made to secure long-term employment and training gains for local people in association with environmental and housing expenditure programmes in their locality. It shows that modest benefits can be achieved and discusses the longer run potential for such initiatives.     

THE DECOMPOSITION OF INCOME INEQUALITY: AN ANALYSIS BASED ON THE NORTHERN IRELAND FAMILY EXPENDITURE SURVEY FOR 1985

This paper conducts an empirical investigation into the issue of inequality decomposition, using the 1985 FES micro data tapes for Northern Ireland. It is hoped that it makes three contributions. First, by using the raw data, it permits a fairly rich disaggregation of individuals. The disaggregation employed in this paper viz. by individuals belonging to different'family types'and individuals of different'economic status'seems particularly relevant to social policy. Second the data also permits a disaggregation of total income by type of income: this permits one to assess, for example, how much of total inequality is caused by inequality in the distribution of income from different sources. Finally, the analysis is consistent with the existing theoretical literature on inequality decomposition.
The main results may be summarized briefly. When the FES sample was divided by subgroups of family type or economic status, then, in 1985, most of income inequality in NI was due to within group rather than to between group inequality. When total income was disaggregated by income type, then inequalities in the distribution of wages and salaries made the largest contribution to the inequality of total income. Prosperous families in NI tended to contain within them a far greater proportion of secondary workers than did the less well off families. It was not implausible therefore that the distribution of employment between families made a major contribution to wage inequalities between them.     

Regulation Fair Disclosure and Earnings Information: Market, Analyst, and Corporate Responses

With the adoption of Regulation Fair Disclosure (Reg FD), market behavior around earnings releases displays no significant change in return volatility (after controlling for decimalization of stock trading) but significant increases in trading volume due to difference in opinion. Analyst forecast dispersion increases, and increases in other measures of disagreement and difference of opinion suggest greater difficulty in forming forecasts beyond the current quarter. Corporations increase the quantity of voluntary disclosures, but only for current quarter earnings. Thus, Reg FD seems to increase the quantity of information available to the public while imposing greater demands on investment professionals.
