This paper argues that skill formation is a life-cycle process and develops the implications of this insight for Scottish social policy. Families are major producers of skills, and a successful policy needs to promote effective families and to supplement failing ones. Targeted early...

We develop an endogenous growth model to quantify how permanent structural policy changes that enhance the fiscal policy mix, markets' functioning, and public institutions' quality affect long-term growth and welfare. The reforms include increased public investment, reduced market power through...

This paper studies the aggregate and distributional implications of Markov-perfect taxspending policy in a neoclassical growth model with capitalists and workers. Focusing on the long run, our main findings are: (i) it is optimal for a benevolent government, which cares equally about its...

The stylized facts suggest a negative relationship between tax progressivity and the skill premium from the early 1960s until the early 1990s, and a positive one thereafter. They also generally imply rising tax progressivity, except for the 1980s. In this paper, we ask whether optimal tax policy...

Nonparametric unit-root tests are a useful addendum to the tool-box of time-series analysis. They tend to trade off power for enhanced robustness features. We consider combinations of the RURS (seasonal range unit roots) test statistic and a variant of the level-crossings count. This combination...

This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that...

This paper develops a dynamic general equilibrium model to highlight the role of human capital accumulation of agents differentiated by skill type in the joint determination of social mobility and the skill premium. We first show that our model captures the empirical co-movement of the skill...

This paper analyses optimal income taxes over the business cycle under a balanced-budget restriction, for low, middle and high income households. A model incorporating capital-skill complementarity in production and differential access to capital and labour markets is de-veloped to capture the...

This paper analyzes the relationship between stock returns and exchange rate changes in international markets and examines how well exchange rate volatility explains movements in stock market returns. The model-based predictions are evaluated on several cost functions. Results from such analysis...
