Abstract We construct a tractable neoclassical growth model that generates Pareto’s law of income distribution and Zipf’s law of firm size distribution from idiosyncratic, firm-level productivity shocks. CEOs invest in risk-free assets as well as their own firms’ risky stocks, through which their assets and incomes depend on firm-level shocks. Using the model, we evaluate how changes in tax rat...

In the context of current concerns about replication in psychological science, we describe 10 findings from behavioral genetic research that have replicated robustly. These are "big" findings, both in terms of effect size and potential impact on psychological science, such as linearly increasing heritability of intelligence from infancy (20%) through adulthood (60%). Four of our top 10 findings...

Access to Britain’s highly-resourced private schools matters because of concerns surrounding social mobility. Using the UK Family Resources Survey, we document a high and mostly stable income concentration school access since 1997. Nevertheless, some low-income participation persists. Bursaries are income-progressive but cannot account for this participation. Housing wealth is, however, found b...

R ecently, a National Science Foundation grant enabled us to establish the Center for Empirically Based Software Engineering. CeBASE seeks to transform software engineering as much as possible from a fad-based practice to an engineering-based practice through derivation, organization, and dissemination of empirical data on software development and evolution phenomenology. The phrase “as much as...

When exercising in a town or city, make use of parks, public spaces and trails with low emission zones as much as possible. A growing amount of research is showing that greenspaces contribute to our health and wellbeing.

Based upon past experience, when undertaking a large, complex, systems project, the realistic expectation should be that the project will fail. In particular, business process reengineering (BPR) projects have an even higher failure rate because of their expanded scope. Hiring a large, established consulting company is no guarantee of success; neither is buying packaged software and implementin...

I've known about conversational implicature a lot longer than I've known Larry. In 1967 I read Grice's " Logical and Conversation " in mimeograph, shortly after his William James lectures, and I read its precursor " (Implication), " section III of " The Causal Theory of Perception " , well before that. And I've thought, read, and written about implicature off and on ever since. Nevertheless, I ...
