External Imbalances and Fiscal Fragility in the Euro Area

This paper presents two views of the European sovereign debt crisis. The first is that countries in the South of the Eurozone were fiscally irresponsible and failed to implement pro-competitive supply side policies. The second view holds that the crisis reflects a deep divide between the external surpluses of the North and external deficits of the South. Basic stylized facts cast doubt on the explanation based on the first thesis alone. A relatively simple model shows how poor fundamentals can create a debt problem independently of fiscal responsibility. The empirical analysis of the determinants of government bond yield spreads relative to Germany suggests that both views in fact provide useful insights into the roots of the current sovereign crisis. However, differences in growth and competitiveness and capital flows between North and South have assumed a much more dominant role since the onset of the global crisis.     

On the Relative Optimality of Environmental Policy Instruments: An Application of the Work of Alberto Alesina

We study the issue of optimality of policies devoted to environmental goals, building upon the recent and interesting work by Alesina and Passarelli (2010) and extending their analysis to the more general framework set up by Weitzman (The Review of Economic Studies 41: 477-491, 1974). We illustrate instruments that governments have at their disposal to reduce polluting emissions, and we point out the economic implications that may arise from the overlapping regulation through both instruments in the European context. We review the literature on political determination of environmental regulation. On the basis of existing literature, we show that political factors are more important than economic ones in explaining why particular instruments are implemented for certain problems (Hepburn et al. Climate Policy 6: 137–160, 2006). We recognize Alesina’s contribution which states that environmental policy, and the decision to adopt one tool instead of another, is subject to a complex political process. Governments are subject to pressure from politicians, households, and firms because their decisions imply winners and losers. Then, we focus in detail on the work by Alesina and Passarelli (2010) who consider which policy tool and at what level would be chosen by majority voting to reduce polluting emissions; they find out that even if a tax is in general superior to quantity based mechanisms (quotas and tradable permits), the majority may strategically choose a quantity mode in order to charge the minority a larger share of the cost for polluting emissions reduction. We extend Alesina’s analysis, focusing on the optimality of price-based mechanisms, since it is not always the case that price instruments are more efficient than quantity instruments. To this aim, we explicitly make use of Weitzman results (The Review of Economic Studies 41: 477–491, 1974), which suggest that if costs are highly nonlinear compared to benefits, then price-type regulation is more efficient, while if costs are close to linear, then quantity-type regulation is more efficient. We cast Alesina’s analysis in the European context, analyzing potential voting outcomes, assuming that EU countries can be arranged according to different criteria. We find that depending on the empirical distribution of voting countries, Alesina’s voting procedure leads to interesting different outcomes.     

Service provision for street-based traders in Pietermaritzburg,KwaZulu-Natal: comparing local findings to lessons drawn from Africa and Asia

South Africa's informal economy absorbs approximately one-quarter of the labour force of 15 million people and is therefore the fastest growing sector of employment. Street-based trading constitutes a major subsector within the informal economy and is continuously expanding through unrelenting proliferation of survivalist micro-enterprises. However, few organisations that support enterprises are accessible or appropriate to survivalist and informal sector micro-enterprises. Interviews were conducted with 98 Pietermaritzburg street-based traders and ten KwaZulu-Natal service providers to determine service provision requirements. The results are compared with findings of four international studies. The findings suggest that for survivalist enterprises to benefit from entrepreneurial education and training services, obstacles with regard to South African traders' understanding of entrepreneurship and cultural limitations to enterprise growth should be overcome. Service institutions also require incentives to serve the informal sector, as well as the capacity to design and deliver appropriate services.     

Mortgage Terminations and Pool Characteristics: Some Additional Evidence

The amount and timing of unscheduled principal amortization determines the ex-post yield to holders of mortgage-backed securities. In this paper, the relationship between pool characteristics and the early return of principal is addressed. Empirical results are based on actual terminations from June 1985 to June 1986 on a sample of all GNMA pools. The relative termination experience of pools with loan rates close to the refinancing rate faced by the underlying borrower is examined in detail. The impact of pool age and size is also considered. Unscheduled termination depends on the refinancing rate, as well as the specific characteristics of a pool.     

THE DIFFERENTIAL EFFECTS OF SINKING FUNDS ON BOND RISK PREMIA

This study analyzes the effect that two options created by the inclusion of a sinking fund clause in a bond indenture have on the bond issue's secondary market risk premium. The impact of market prices that exceed current sinking fund redemption prices, and of par versus premium redemption, is clearly apparent when a set of issue-specific and macroeconomic control variables are incorporated into a model of bond risk premia. Thus, secondary market prices for the large-volume utility bond transactions in the sample reflect knowledge of individual-issue, time-varying indenture characteristics.     

A survey of cross-sectional and time-series literature on factors affecting child welfare

This paper reviews the literature on the socio-economic determinants of child welfare. Cross-sectional evidence is first analysed. The relevant literature is subdivided into four groups of studies depending on the main factors influencing child welfare: demographic; related to family circumstances; related to health care and sanitation; and economic. The very few time-series studies on this subject are then examined. While the existing literature does not allow definitive conclusions to be drawn on the predominance or relative importance of these four sets of factors, this paper identifies three related research areas for which particularly severe gaps seem to emerge and for which additional investigation appears necessary. These are: over-time studies, studies for low-income, high-mortality countries of Africa, for middle-income countries and for high-income, high-mortality countries, and studies measuring impact on the basis of indicators of welfare other than infant mortality rates.
