The development of the longbow in late medieval England and ‘technological determinism’

Traditional understandings of the development of the medieval English longbow and its role in the fourteenth-century ‘infantry revolution’ have recently been challenged by historians. This article responds to the revisionists, arguing based on archaeological, iconographic and textual evidence that the proper longbow was a weapon of extraordinary power, and was qualitatively different from – and more effective than – the shorter self-bows that were the norm in England (and western Europe generally) before the fourteenth century. It is further argued that acknowledging the importance of the weapon as a necessary element of any credible explanation of English military successes in the era of the Hundred Years War does not constitute ‘technological determinism’.     

Representing Structural Change in U.S. Migration Patterns

This paper focuses on the identification of three sets of relationships exhibited by a time series of age-specific national migration rates and multiregional transition probability matrices: the relationship across time for the same age group, as defined by period (temporal) transformation coefficients or matrices; the relationships across age at a particular moment in time, as defined by age transformation coefficients or matrices; and the relationships across time and age, as defined by cohort transformation coefficients or matrices. Given any two of these relationships one can solve for the third. This feature of age-period-cohort relationships has a practical application in the development of improved methods for representing structural change in migration patterns over time and for indirectly estimating migration patterns using inadequate data.     

Evaluating marital stability in late-Victorian Camberwell

What was the extent of marital breakdown and separation in a society where divorce was unlikely to be an option? This article investigates the status and longevity of the marriages of a group of parents whose children were admitted to the care of the poor law authorities in Camberwell in the latter part of the nineteenth century. It finds that spousal death or misfortune, rather than marital breakdown, were the primary reasons for a parent to send a child to the poor law authorities, and that most of the marriages of the parents in the sample remained intact. It also explores whether those who separated formed new co-residential relationships.     

LEADERS,FOLLOWERS, AND ASYMMETRIC LOCAL TAX POLICY DIFFUSION

Complementing recent theoretical models of tax competition with endogenous leadership, we empirically model local policy diffusion as a dynamic asymmetric process. Using a setting where local option sales taxes rapidly transitioned from nonexistence to ubiquity, we construct a policy leadership index to classify jurisdictions as leaders or followers. Using models that control for vertical tax competition effects, we show how asymmetric leader–follower dynamics characterize horizontal tax competition over the three decades that follow. A placebo test further supports our main conclusions. This methodological approach could be adapted to other settings where policies exhibit both extensive and intensive margins.
