Emigration State: Race,Citizenship and Settler Imperialism in Modern British History,c. 1850–1972

What role did migration play in the making of modern Britain? We now have a good sense of how ethnicity, class, religion and gender structured immigrants' experience and what impact they had on Britain's culture, society and economy. But as Nancy Green pointed out almost two decades ago, scholars of migration must focus on exit as well as entry. Such a call to study ‘the politics of exit’ is especially apposite in the case of the UK. For in every decade between 1850 and 1980 (with the exception of the 1930s), the UK experienced net emigration year on year. This article analyses this outflow of migrants to reveal a new vision of the UK as an ‘emigration state’. The article employs this concept to make a new argument about the formation of migration policy in the UK and offers a revised account of the geographical boundaries of the modern British state.     

Government Debt and Excess Sensitivity of Private Consumption: Estimates from OECD Countries

This article investigates the role of government debt in the degree of excess sensitivity of private consumption to current disposable income. Because this type of excess sensitivity is generally attributed to liquidity constraints, this amounts to a test of the impact of government debt on the amount of credit extended to individuals. Controlling for financial liberalization we find that, for a panel of OECD countries in the 1990s, a high government debt leads to more excess sensitivity. This result supports the idea that a high government debt induces lenders to tighten credit conditions. Our findings survive several robustness checks.

Pension reform, employment by age, and long-run growth

We study the effects of pension reform on hours worked by three active generations, education of the young, the retirement decision of older workers, and aggregate growth in a four-period OLG model. The model explains important facts well for many OECD countries. Our simulation results prefer an intelligent pay-as-you-go system above a fully funded private system. Positive effects on employment and growth are the strongest when the pay-as-you-go system includes a tight link between individual labor income and the pension, and when it attaches a high weight to labor income earned as an older worker to compute the pension assessment base.     

No overall effect of urbanization on nest-dwelling arthropods of great tits (Parus major).

Urbanization has been shown to strongly affect community composition of various taxa with potentially strong shifts in ecological interactions, including those between hosts and parasites. We investigated the effect of urbanization on the composition of arthropods in nests of great tits in Flanders, Belgium. These nests contain taxonomically and functionally diverse arthropod communities including parasites, predators, detritivores and accidental commensals. Using a standardized hierarchical sampling design with subplots (200 m?×?200 m) nested in plots (3 km?×?3 km) of varying urbanization levels, we collected arthropods from nests of resident great tits after the young had fledged. Arthropods were extracted, identified to Primary Taxonomical Groups (PTG) and counted. Using generalized linear mixed models (GLMMs) we found diverging effects of urbanization on PTG occurrences and abundances at various levels, but we did not find an overall signal in arthropod diversity or richness. Also, visual inspection of non-metric multidimensional scaling (NMDS) plots did not reveal any community differences between urbanization levels at plot or subplot scales. Land use and environmental variables at different distances around nestboxes did not contribute much to the variation between communities. Our results indicate that arthropod nestbox communities are generally not adversely affected by urbanization, and even city gardens and parks harbor comparable communities to forests and suburban areas. We thus found no evidence for a parasite release effect due to urbanization, nor an increased risk of parasitism in human-dominated environments.

     

Real versus Nominal Convergence: National Labour Markets and the European Integration Process

ABSTRACT: This paper investigates the role of national labour market characteristics for the chances of successful transition to EMU in Europe as well as for its viability The conclusions are rather pessimistic Although overlooked by the Maastricht Treaty the need for real convergence (I e convergence of real macroeconomic variables like unemployment) is emphasized as a major condition for success However current labour market characteristics in the EC make it quite unlikely that this condition will be fulfilled We show that the implementation of the Maastricht programme might turn into an obstacle to monetary unification     

Sensitivity analysis for variance parameters in Bayesian simplex mixed models for proportional data

In this article, we present a Bayesian modeling for response variables restricted to the interval (0, 1), such as proportions and rates, using the simplex distribution for cases in which data have a longitudinal form, taking random effects into account. In order to investigate the stability of posterior distribution, we study through sensitivity analysis, the effect of three different uniparametric prior distributions for variance parameters of random effect on the final estimation. For this purpose, we consider homogeneous and heterogeneous structures for parameters in location and dispersion submodels. Models and results are illustrated with simulated and real data application.
