Temporal causality and the dynamics of democracy,emigration and real income in Fiji

This study is the first to explore temporal causality between democracy, emigration and real income in Fiji within a multivariate cointegration model. We find three long run relationships between democracy, emigration and real income. In the long run there is evidence that migration and democracy Granger cause real GDP in Fiji; real GDP and democracy Granger cause migration from Fiji and that real GDP and migration Granger cause democracy in Fiji. In the short run we find unidirectional Granger causality running from migration to real GDP and from democracy to real GDP, but neutrality between democracy and migration in the short run. We also extend the analysis to examine the degree of exogeneity of the variables beyond the sample period through considering the decomposition of variance and impulse response functions.     

WHAT DETERMINES MIGRATION FLOWS FROM LOW‐INCOME TO HIGH‐INCOME COUNTRIES? AN EMPIRICAL INVESTIGATION OF FIJI–U.S. MIGRATION 1972–2001

This article examines the long-run and short-run determinants of migration from Fiji to the United States between 1972 and 2001 using a human capital framework, which is extended to take account of political instability in Fiji. In the long-run the authors find that differences in income levels, disparities in police strength, disparities in the number of doctors, costs of moving, and political instability in Fiji are all statistically significant with the expected sign. In the short run the cost of moving, lagged migration, political instability, and differences in both police strength and medical care are the main determinants of Fiji–United States immigration.

Effect of World Fertility Scenarios on International Living Standards

This paper applies a two good, multi-region Ramsey-Solow model of the world economy to determine the impact that alternative world fertility rates would have on international capital markets and living standards. Notable features of the model include: relative consumption demands and relative employment efficiencies that vary by age, traded and non-traded goods, vintage technology, outward-looking reference consumption, a proportion of non-optimising rule-of-thumb consumers and imperfect capital mobility due to asymmetric information. The model suggests that projected demographic change will imply a flow of international capital from the ageing regions to the younger regions; and that the world interest rate will fall. The lower world interest rate will cause a loss in living standards for ageing regions, the lenders, and a gain for the younger regions, who are borrowers.     

ARE LABOUR FORCE PARTICIPATION RATES NON‐STATIONARY? EVIDENCE FROM 130 YEARS FOR G7 COUNTRIES*

This paper applies a unit root test with a non‐linear threshold to examine whether labour force participation rates are mean reverting for G7 countries using annual data over a 130 year period. We find some evidence of mean reversion for just over half the sample; however, this result is sensitive to regime shifts. We also examine whether the labour force participation rate is trend reverting through employing a lagrange multiplier (LM) unit root test with one and two structural breaks in the intercept and slope. The LM unit root test provides no additional evidence in support of stationarity. On the basis of the unit root tests for mean reversion we conclude that there is at best mixed evidence that long‐term changes in unemployment rates translate into long‐term changes in employment rates and that the unemployment rate is a useful indicator of joblessness.     

What Determines Research Output of Academic Economists?

This paper looks at the characteristics that explain research productivity in a cross section of academic economists. From a sample of 150 economists, we obtained data on a range of human capital variables, teaching loads and research funding. The results suggest that human capital variables, particularly the grade of honours and the nature and location of the PhD., are especially important in explaining a quality-weighted research output measure. Teaching loads are also significant. In particular, we find that a 10 per cent increase in the number of teaching hours may reduce research output by as much as 20 per cent, whereas a 10 per cent increase in the number of grants held per year may raise output per year by as much as 15 per cent.     

New Institutional Economics in the Post-Socialist Transformation Debate

The paper suggests that there is a tension between the basic tenant of New Institutional Economics (NIE) and the manner in which it has been applied in the debate on post-socialist transformation. This tension is explored in the context of four main perspectives on NIE: (i) property rights, (ii) transaction costs economics, (iii) new economic history, and (iv) evolutionary economics. There are two main arguments. The first is that the transformation phase should be seen as 'open-ended' rather than a 'closed process' where the 'pure market' is the inevitable end result. The second is that, although the NIE literature touches on most of the issues which are relevant to post-socialist transformation, the insights that it offers are still too general for policy guidance.     

The Introduction of Choice of Superannuation Fund: Results to Date

Commonwealth legislation providing for choice of superannuation fund has now been in operation since 1 July 2005. This paper explores the extent to which employees have exercised choice in the period immediately following the implementation of fund choice. The data available suggest that choice of fund has had only a modest impact. However, while community awareness of superannuation has increased and the level of member attachment to the main superannuation fund has increased, a downturn in investment returns, and subsequently in member sentiment, could have a significant impact on member preparedness to choose another fund     

A Measure of Competition Based on 10‐K Filings

In this paper we develop a measure of competition based on management's disclosures in their 10‐K filing and find that firms’ rates of diminishing marginal returns on new and existing investment vary significantly with our measure. We show that these firm‐level disclosures are related to existing industry‐level measures of disclosure (e.g., Herfindahl index), but capture something distinctly new. In particular, we show that the measure has both across‐industry variation and within‐industry variation, and each is related to the firm's future rates of diminishing marginal returns. As such, our measure is a useful complement to existing measures of competition. We present a battery of specification tests designed to explore the boundaries of our measure and how it varies with the definition of industry and the presence of other measures of competition.
