A prospective analysis of labour market status and self-rated health in the UK and Russia

Comparing prospective data from the UK and Russia, this paper analyzes whether the association of labour market status, and particularly unemployment, with subsequent health varies by the level of state protection provided to the unemployed. While the UK's unemployment welfare regime is classified as providing minimal protection, the Russian regime is sub-protective. Employing Cox duration analysis upon data from the Russian Longitudinal Monitoring Survey and the British Household Panel Survey for the period 2000–2007, this study finds that labour market status and economic circumstances independently predicted individual-level declines in self-rated health and, contrary to expectations, the associations of unemployment with health decline were similarly sized in the two countries.     

AIDS mortality and its effect on the labor market: Evidence from South Africa

This paper investigates how HIV/AIDS has impacted the labor market in South Africa, focusing on its effect on wages and employment. This is done by matching individual level data with group specific cumulative AIDS mortality rates. Exploiting the panel nature of the data, I remove individuals whose productivity is most likely impacted by HIV/AIDS, and find evidence that cumulative AIDS mortality has led to reductions in wages of between 3 and 6% for the African population group (Black South Africans). Furthermore, I also find evidence that the epidemic has lowered employment in South Africa. This result is concentrated among those with the lowest levels of education and employment. Although not large in magnitude, these effects are widespread across a significant portion of the population, contributing to a substantial loss of income throughout the South African economy.     

Human capital externalities Evidence from the transition economy of Russia1

The paper tests for the existence of human capital externalities using a micro‐level approach: the Mincerian wage regression augmented with the average level of education in cities. To solve identification problems arising from the endogeneity of average education, the study exploits a natural experiment provided by the process of economic transition: average education at the end of communism can be seen as exogenous in respect of wages prevailing after the start of transition. Our empirical results based on the RLMS data show that a 1 percentage point increase in the share of city residents with a university degree results in an increase of wages of city residents by about 1 percent.     

Death and prices

Most experts agree that alcohol abuse has been a major cause of Russia’s soaring mortality rate. But why have ever more Russians been drinking themselves to death? Some attribute this to despair in the face of painful economic change. I present evidence that, in fact, the surge in alcohol‐related deaths – and premature deaths in general – was fuelled by a dramatic fall in the real price of vodka, which dropped 77 percent between December 1990 and December 1994. Variation in vodka prices – both over time and across Russia’s regions – closely matches variation in mortality. Although market competition and weak excise collection help explain the fall in prices, the main reason appears to be populist price regulation during inflationary periods.     

Social evaluations when populations differ in size

Assessments of “social welfare” do not usually take into account population sizes. This can lead to serious social evaluation flaws, particularly in contexts in which policies can affect demographic growth. We develop in this paper a little‐known though ethically attractive approach to correcting the flaws of traditional social evaluations, an approach that is sensitive to population sizes and that is based on critical‐level generalized utilitarianism (CLGU). Traditional CLGU is extended by considering arbitrary orders of welfare dominance and ranges of “poverty lines,” as well as values for the “critical level” of how much a life must be minimally worth to contribute to social welfare. We apply these social evaluation methods to rank Canada across 1976, 1986, 1996 and 2006 and to estimate normatively and statistically robust lower and upper bounds of critical levels over which these rankings can be made.     

Relative Price Changes and Households' Welfare in Italy

The entrance of Italy in the Euro area in 2001 has given rise to a wide debate about the perception of inflation on households' well‐being. However, most of the debate has involved the measurement of the “correct” consumer price index at the national level. Much less analysis has been carried out on the distributional consequences of inflation on every household. The paper addresses this issue by performing a microsimulation analysis of the impact of inflation on Italian households in the period 1997–2007. It is shown that the impact of inflation has an ambiguous path over the period, with a large concentration of welfare losses around the introduction of the Euro currency. In particular, it is found that poorer and larger households are severely hurt by inflation and that the prices of gas and gasoline are largely responsible for determining the living conditions of Italian households.     

Does the Welfare State Destroy the Family? Evidence from OECD Member Countries

We study the effect of the size of the welfare state on demographic trends in OECD member countries. Exploiting exogenous variation in public social spending, due to varying degrees of political fractionalization (i.e., the number of relevant parties involved in the legislative process), we show that an expansion in the welfare state increases fertility, marriage, and divorce rates with a quantitatively stronger effect on the marriage rate. We conclude that the welfare state supports family formation in the aggregate. Further, we find that the welfare state decouples marriage and fertility, and therefore alters the organization of the average family.     

Food security in Kenya: Insights from a household food demand model

This paper evaluates the household food security situation in Kenya in terms of access to food. We apply a quadratic almost ideal demand system (QUAIDS) model to nationally representative household survey data from Kenya, and estimate and interpret price and expenditure elasticities as indicators of household sensitivity to market shocks. Our estimation results show positive expenditure elasticities, close to unity, while all compensated and uncompensated own-price elasticities are negative and smaller in magnitude. A complementary welfare analysis shows high compensated variations in the long run, ranging between 34% and 131% across food groups. This suggests that rising relative food costs have led to deterioration of the food security situation in Kenya, and the most severely affected households seem to be those that rely on informal markets and reside in rural areas. To improve food security, targeted income support could be a more effective policy than price support, given the much higher estimated expenditure elasticities.     

On Clustering in the Location of R&D: Statics and Dynamics

Empirical analyses of research and development find strong evidence that these activities tend to cluster geographically. Clusters are thought to emerge from the presence of localized positive externalities. This paper presents a model of this clustering behaviour. We find that phase changes in clustering exist both as the strength of local externalities changes and as the degree of heterogeneity among firms changes. The dynamics of the system are examined as it responds to shocks to the size of the market for R&D output, and the length scale of the spatially dependent externalities. Dynamic responses take place in two distinct stages: a rapid response to the change in market systems which takes place throughout the space, with litlle regard to externality effects; followed by a slow re-agglomeration process as producers change their spatial decisions to lower the costs of the new production level.
