INTERNATIONAL SCHOOL TEST SCORES AND ECONOMIC GROWTH

Hanushek and Kimko's analysis of the relationship between growth and schooling quality, as measured by scores in international tests, suffers from potential endogeneity as schooling quality is not always measured at a date strictly prior to the observed growth. To address this problem we treat the data as a panel, relating growth only to test scores at earlier dates. The estimates of the effect of schooling quality on growth are similar to those obtained from cross‐section regressions.     

Can emerging market central banks bail out banks? A cautionary tale from Latin America

This paper investigates whether emerging market countries can implement monetary policies to cope with financial crises as advanced countries did during the recent global crisis—injecting significant amounts of money into the financial system without facing major short-run adverse macroeconomic repercussions. Using panel data techniques, the paper analyzes episodes of financial turmoil in 16 Latin American countries during 1995–2007. The results show that developing and emerging market countries should be cautious because injecting money on a large scale into the financial system may fuel further macroeconomic instability, increasing the chances of simultaneous currency crises.     

Measuring absorptive capacity constraints to foreign aid

To assist with progress towards the United Nations Millennium Development Goals (MDGs) in developing countries, the international community is scaling-up foreign aid to record levels. Concurrently, there are concerns that additional aid will not be used effectively due to a problem of absorptive capacity in recipient countries. Empirical studies lend support to these concerns with many finding that there are diminishing returns to foreign aid. This paper reviews the extensive aid effectiveness literature to identify the various dimensions of absorptive capacity. It proceeds by devising a composite index of absorptive capacity for individual recipient countries which can assist policymakers in guiding the allocation of their aid. The relevance of the index is confirmed through its employment in a standard empirical model of aid effectiveness. The paper highlights the developing countries that currently receive high levels of aid relative to their estimated level of absorptive capacity.     

The impact of the ‘school run’ on road traffic accidents: A spatio-temporal analysis

Engineering and improved road safety education has resulted in an overall decrease in road traffic accident numbers in Christchurch, New Zealand. The temporal trends of crash data from 1980 to 2004 reveal that lowering of crash rates is not occurring at a uniform rate throughout the day, with comparative increases in crash rates occurring during morning rush hour, and during the ’school run’. No spatial clustering around schools was identified. This suggests that policies to reduce school travel related road accidents need to be focused on reducing overall traffic levels rather than focusing geographically on areas in the immediate vicinity of schools.     

Contrasting paradigms: segmentation and competitiveness in the formation of the chinese labour market

An urban labour market is in the process of being formed in China. The objective of this paper is to analyse the stage that it has reached. A 1999 household survey is used to investigate whether the labour market has three tiers comprised of recently retrenched and re-employed urban workers, non-retrenched urban workers, and rural–urban migrants. It tests whether wage levels and structures differ across these categories of worker. Panel data are used to model the evolution of the wage structure and, specifically, the impact of retrenchment and re-employment. The results indicate that non-retrenched urban workers enjoy a wage premium, although migrants receive similar returns to education. Re-employed workers receive no return to education and appear to have lost out on the wage rises enjoyed by the non-retrenched. There is evidence to suggest that the urban labour market is segmented into these categories, which differ in their openness to market competition. The urban labour market has a long way to go before it is fully competitive.     

Advertising's Sales Effect Can Be Measured and Evaluated Very Well

Not long ago businessmen despaired because they thought that advertising's effects could not be measured at all. Now they despair because they think that measuring advertising's effects must always be a super-complicated mumbo-jumbo of econometrics and other arcane techniques that can only be understood by experts. There is no need to despair.     

Labor market integration policies and the convergence of regions: the role of skills and technology diffusion

We study the role of different labor market integration policies on economic performance and convergence of two distinct regions in an agent-based model. Production is characterized by a complementarity between the quality of the capital stock and the specific skills of workers using the capital stock. Hence, productivity changes in a region are influenced both by the investment of local firms in high quality capital goods and by the evolution of the specific skill distribution of workers employed in the region. We show that various labor market integration policies yield, via differing regional worker flows, to distinct regional distributions of specific skills. Through this mechanism, relative regional prices are affected, determining the shares that the regions can capture from overall consumption good demand. There occurs a trade-off between aggregate output and convergence of regions with closed labor markets resulting in relatively high convergence but low output, and more integrated labor markets yielding higher output but lower convergence. Furthermore, results differ substantially in several respects as distinct labor market opening policies are applied.     

THE EXPECTED SHORTFALL OF QUADRATIC PORTFOLIOS WITH HEAVY‐TAILED RISK FACTORS

Computable expressions are derived for the Expected Shortfall of portfolios whose value is a quadratic function of a number of risk factors, as arise from a Delta–Gamma–Theta approximation. The risk factors are assumed to follow an elliptical multivariate t distribution, reflecting the heavy‐tailed nature of asset returns. Both an exact expression and a uniform asymptotic expansion are presented. The former involves only a single rapidly convergent integral. The latter is essentially explicit, and numerical experiments suggest that its error is negligible compared to that incurred by the Delta–Gamma–Theta approximation.     

Time varying VARs with inequality restrictions

In many applications involving time-varying parameter VARs, it is desirable to restrict the VAR coefficients at each point in time to be non-explosive. This is an example of a problem where inequality restrictions are imposed on states in a state space model. In this paper, we describe how existing MCMC algorithms for imposing such inequality restrictions can work poorly (or not at all) and suggest alternative algorithms which exhibit better performance. Furthermore, we show that previous algorithms involve an approximation relating to a key prior integrating constant. Our algorithms are exact, not involving this approximation. In an application involving a commonly used U.S. data set, we present evidence that the algorithms proposed in this paper work well.     

Information sharing and group efficacy influences on communication and decision quality

Group efficacy has generally been found to have a positive effect on group performance. This study reveals a less favorable consequence of high group efficacy, its tendency to promote inferior group decisions under certain circumstances. Previous studies have found that members in a group generally exhibit bias towards utilizing shared information to make decisions. This study examines the effect of group efficacy on both the process (in terms of communication) and outcomes (in terms of decision quality and deviation from initial individual preference) of group decision-making. When information was not completely shared by group members prior to group discussion, members of low-efficacy groups communicated more and more readily changed their initial decision preferences. In the end, they were able to make objectively better decisions. These effects of group efficacy were even more pronounced when individual group members had conflicting information in the beginning about the issues prior to group discussion.
