Labour Market Policy Developments in Japan: Following an Australian Lead?

In recent times, Japan has experienced a rapid expansion in its service sector, increases in casual and part‐time employment and record unemployment. In addition, there has been an associated rise of freeters and NEETs—predominantly young workers with tenuous labour market attachment. While somewhat slow in initiating policy responses, the Japanese government responded to these structural changes by reforming its existing employment policies. In this article we argue that recent changes in the nature of Japan's labour market policies appear to have been driven by some of the same factors which led to the radical overhaul of Australia's own labour market policies.     

Seasonal Migration and Improving Living Standards in Vietnam

We use panel data methods to explore whether households in Vietnam used seasonal migration to increase their living standards during the 1990s. Using per capita expenditures as our primary measure of living standards and historical and latent network variables as instruments for migration, we can attribute 5.2 percentage points of annualized expenditure growth to increased migration. The results are robust to several alternative measures of living standards. As the estimates suggest migration accounts for a 3 percentage point decrease in the poverty headcount, we conclude migration played an important role in the improvement of living standards observed in Vietnam.     

The future of food demand: understanding differences in global economic models

Understanding the capacity of agricultural systems to feed the world population under climate change requires projecting future food demand. This article reviews demand modeling approaches from 10 global economic models participating in the Agricultural Model Intercomparison and Improvement Project (AgMIP). We compare food demand projections in 2050 for various regions and agricultural products under harmonized scenarios of socioeconomic development, climate change, and bioenergy expansion. In the reference scenario (SSP2), food demand increases by 59–98% between 2005 and 2050, slightly higher than the most recent FAO projection of 54% from 2005/2007. The range of results is large, in particular for animal calories (between 61% and 144%), caused by differences in demand systems specifications, and in income and price elasticities. The results are more sensitive to socioeconomic assumptions than to climate change or bioenergy scenarios. When considering a world with higher population and lower economic growth (SSP3), consumption per capita drops on average by 9% for crops and 18% for livestock. The maximum effect of climate change on calorie availability is ?6% at the global level, and the effect of biofuel production on calorie availability is even smaller.     

The relationship between production and unemployment in Japan: Okun's law in comparative perspective

This paper studies the question whether the celebrated ‘Okun's law’, a relation between excess capacity and unemployment, applies to the postwar Japanese economy. Though the fitness of estimation is weak, the coefficient that measures the responsiveness of the output gap to the unemployment rate is very large, reaching 28. This large coefficient can be attributed to the elastic response in the female participation ratio, to flexible working hours, to the slow adjustment in employment, and to changes in industrial structures. The results are compared with those in the United States.     

Population growth and the transfer paradox in an overlapping generations model

This study investigates whether the transfer paradox (donor enrichment and/or recipient impoverishment) occurs when a donor and a recipient have different population growth rates by using a one‐sector, two‐country overlapping generations model. We show that if the population growth rates differ, neither donor enrichment nor recipient impoverishment occurs in the steady state under dynamic efficiency. This result is in stark contrast to the existing results that the transfer paradox might occur when a donor and a recipient country have different marginal propensities to save, assuming that both have the same population growth rate. Furthermore, we present the condition for the transfer problem to occur on the transition path and show that the transfer paradox is less likely to occur as the economy converges to the steady state. Our result shows that the prevailing finding that the transfer paradox can occur in an overlapping generations model is limited to the special case of countries having the same population growth rate.     

An empirical analysis of the relationship between economic development and population growth in China

China has experienced a dramatic demographic transition since the latter half of the twentieth century, and thus, assessing the global economic implications is an important issue. This article uses time-series data on China to estimate the determinants of gross domestic product (GDP) per capita. According to the results of the presented co-integration analysis, population has a significantly negative impact on GDP per capita, while savings rate, total factor productivity and degree of industrialization have significantly positive impacts on GDP per capita. These results suggest that the share of the working-age population relative to the total population does not have a strong influence on GDP per capita. Therefore, the contribution of the working-age population to economic growth might not be as large as previously assumed. It is also possible that an increase in savings, remarkable industrialization and rapid technological progress have all stimulated economic growth in China greatly.
