A rise in population caused by increased immigration, is sometimes accompanied by concerns that the increase in population puts additional or differential pressure on welfare services which might affect the net fiscal contribution of immigrants. The UK and Germany have experienced significant...

This paper studies the impact of NAFTA on informality and real wages in Mexico. Using a dynamic industry model with firm heterogeneity, it is predicted that import tariff elimination could reduce the incidence of informality by making more profitable to some firms to enter the formal sector,...

The Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996 represents a dramatic change in the US welfare state. One of its key goals was to move lone mothers, even those with young children, from welfare to work. Early evidence suggests that, in concert with a strong...

We examine whether the information contained in social media (Twitter & Facebook) and web search queries (Google) influences financial markets. Using a multivariate system and focussing on Eurozone’s peripheral countries, the GIIPS (Greece, Ireland, Italy, Portugal and Spain), we show that...

Allowing for a richer information structure than usual, we show that rational traders’ calculation with short-term price fluctuations may heavily influence their behaviour even if the interim price is not influenced by non-rational agents i.e. there is no noise trader risk. Instead, traders...

This paper solves for optimal international portfolio choice in the presence of liquidity constraints and undiversifiable labor income risk. Optimal portfolios are internationally diversified while positive correlation between domestic stock market returns and permanent labor income shocks can...

Motivated by the success of internal habit formation preferences in explaining asset pricing puzzles, we introduce these preferences in a life-cycle model of consumption and portfolio choice with liquidity constraints, undiversifiable labor income risk and stock-market participation costs. In...

This paper shows that in a non-representative agent model in which households face short selling constraints and labor income risk, in the form of both uninsurable shocks and a common aggregate component, small differences in the correlation between aggregate labor income shocks and domestic and...

We solve a model with incomplete markets and heterogeneous agents that generates a large equity premium, while simultaneously matching stock market participation and individual asset holdings. The high risk premium is driven by incomplete risk sharing among stockholders, which results from the...

This paper extends the model proposed by Goodhart, Sunirand, and Tsomocos (2003, 2004a, b) to an infinite horizon setting. Thus, we are able to assess how the model conforms with the time series data of the U.K. banking system. We conclude that, since the model performs satisfactorily, it can be...
