LOCAL RISK MINIMIZATION FOR DEFAULTABLE MARKETS

We study the local risk minimization approach for defaultable markets in a general setting where the asset price dynamics and the default time may influence each other. We find the Föllmer-Schweizer decomposition in this general setting and compute it explicitly in two particular cases, when default time depends on the risky asset's behavior and when only a dependence of discounted asset price on default time is occurring.     

Financial integration, productivity and capital accumulation

Understanding the mechanism through which financial globalization affects economic performance is crucial for evaluating the costs and benefits of opening financial markets. This paper is a first attempt at disentangling the effects of financial integration on the two main determinants of economic performance: productivity (TFP) and investment. I provide empirical evidence from a sample of 70 countries observed between 1975 and 1999. The results for both de jure and de facto indicators suggest that financial integration has a positive direct effect on productivity, while it does not directly affect capital accumulation. I also control for indirect effects of financial globalization through financial development and banking and currency crises. While financial integration does not systematically increase domestic financial depth, it may raise the likelihood of banking crises, though only to a minor extent. Yet, the overall effect of financial liberalization remains positive for productivity and negligible for investment.     

The Role of Market Size in the Formation of Jurisdictions

Administrative and political reorganization is being actively debated even in the mature, stable economies of Western Europe. This paper investigates the possibility that such a reorganization is tied to the integration of economic markets. The paper describes a model where heterogeneous individuals form coalitions for the provision of a public good and shows that the number and composition of these jurisdictions depend on the overall size of the market. The range of economic activities engaged in by jurisdiction members increases when the size of the market increases, and so does the range of their preferences over the public good. The result is a change in the endogenous borders of the jurisdictions, and a reorganization of all coalitions. The optimal number of jurisdictions is unique and increases with market size. In the absence of compensating transfers, however, the decentralized equilibrium need not be optimal and is not unique, although     

Long-run consequences of finite exchange rate bubbles

This paper draws on the literature on exchange rate instability and on sunk-cost hysteresis to analyze the long-run effects of exchange rate bubbles. To address the issue, after discussing the implications of sunk-cost hysteresis for aggregate supply, we propose two versions of the Dornbusch (1976) model of exchange rate determination. We modify it so as to allow for endogenous adjustment in productive capacity, with the aggregate investment function being linear with respect to the exchange rate in one version and non-linear in the other. For both versions, we provide solutions for a Blanchard-type bubble developing on the foreign exchange market. We find that, if capacity adjusts non-linearly, such a bubble will affect the steady state of the economy.     

The hidden work of coping: gender and the micro-politics of household consumption in times of austerity

Abstract

This article explores the coping strategies of women in 10 middle-class Italian families facing economic crisis. We investigate food provision revealing the ceaseless extra work that goes into meal preparation. Adopting anthropological theories of thrift and sacrifice, we unpack participants’ micro-coping strategies, observing their tendency to redirect resources towards their loved ones and abnegating their own needs for the greater good of the family. This sacrifice is done out of necessity, reinforcing traditional gender inequalities in the home. However, there is also evidence that women take pride in their coping, developing new competencies and maintaining control over meal provision and thus the wider patterning of family life. We explore the significance of recessionary times for the constitution of female subjectivities at home.     

Do illegal migrants compete with national workers?

Conclusion  Some evidence regarding the effects of illegal or irregular immigrants on the receiving country's labour market is available but it is very limited considering the complexity entailed. It is clear that foreign irregular labour damages native workers more than regular foreign labour, but irregularity in employment is very difficult to pursue in countries with a large informal sector. Destination countries should first fight complete illegality in the country and in the job at any cost, and leave the labour office with the responsibility of providing incentives to get a legal job through frequent controls and high penalties.     

Firms’ growth: Does the innovation system matter?

The paper investigates the effects of external sources of knowledge on firm growth. In line with the knowledge spillovers literature, we focus on the relationship between firms and universities, considered as a crucial source of knowledge. To this purpose, we analyse a sample of UK public companies in the period 1995 to 2006. Our findings confirm that both universities’ knowledge input and output are important determinants of the growth of entrepreneurial firms.
